如何在android中创建自定义对话框？

Question

我想创建一个自定义对话框,如下所示

我尝试过以下的事情.

1. 我创建了AlertDialog.Builder的子类,并使用了自定义标题和自定义内容视图并使用了它,但结果并不像预期的那样.

2. 另一种尝试是继承DialogFragment并在onCreateDialog中自定义对话框,但结果不是预期的.

3. 然后我尝试使用普通的Dialog类.结果并不像预期的那样.

在所有三种情况下,问题是当我忽略标题视图时,对话框的大小不是预期的,当我使用标题视图时,结果是内容视图周围有一个粗边框(实际上看起来很糟糕).现在我脑子里有两个问题......

1. 我怎样才能做到这一点？由于我已经尝试了很多东西,因此我们将更加赞赏直接的答案.

2. 在Android应用程序中显示错误或警告对话框的最佳方法是什么？

编辑 Android开发人员文档建议我们应该使用DialogFragments或Dialogs向用户显示错误/警报消息.但有一次他们说......

提示:如果需要自定义对话框,则可以将"活动"显示为对话框,而不是使用"对话框API".只需创建一个活动,并将其主题设置为清单元素中的Theme.Holo.Dialog.

那是什么意思？使用Activity只是为了显示错误消息是不是太多了？

在这里,我创建了一个简单的Dialog,如:

custom_dialog.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="80dp"
    android:background="#3E80B4"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/txt_dia"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:layout_margin="10dp"
        android:text="Do you realy want to exit ?"
        android:textColor="@android:color/white"
        android:textSize="15dp"
        android:textStyle="bold"/>


    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:background="#3E80B4"
        android:orientation="horizontal" >

        <Button
            android:id="@+id/btn_yes"
            android:layout_width="100dp"
            android:layout_height="30dp"
            android:background="@android:color/white"
            android:clickable="true"
            android:text="Yes"
            android:textColor="#5DBCD2"
            android:textStyle="bold" />

        <Button
            android:id="@+id/btn_no"
            android:layout_width="100dp"
            android:layout_height="30dp"
            android:layout_marginLeft="5dp"
            android:background="@android:color/white"
            android:clickable="true"
            android:text="No"
            android:textColor="#5DBCD2"
            android:textStyle="bold" />
    </LinearLayout>

</LinearLayout>

你必须extends Dialog和implements OnClickListener

public class CustomDialogClass extends Dialog implements
    android.view.View.OnClickListener {

  public Activity c;
  public Dialog d;
  public Button yes, no;

  public CustomDialogClass(Activity a) {
    super(a);
    // TODO Auto-generated constructor stub
    this.c = a;
  }

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.custom_dialog);
    yes = (Button) findViewById(R.id.btn_yes);
    no = (Button) findViewById(R.id.btn_no);
    yes.setOnClickListener(this);
    no.setOnClickListener(this);

  }

  @Override
  public void onClick(View v) {
    switch (v.getId()) {
    case R.id.btn_yes:
      c.finish();
      break;
    case R.id.btn_no:
      dismiss();
      break;
    default:
      break;
    }
    dismiss();
  }
}

如何拨打电话？

R.id.TXT_Exit:
CustomDialogClass cdd=new CustomDialogClass(Values.this);
cdd.show();  

更新

很长一段时间后,我的一个朋友让我做了一个透明背景的弯曲形状对话框.所以,我在这里实现了它.

要制作弯曲的形状,您需要创建一个单独的curve_shap.XML,如下所示,

<shape xmlns:android="http://schemas.android.com/apk/res/android" >

    <solid android:color="#000000" />

    <stroke
        android:width="2dp"
        android:color="#ffffff" />

    <corners
        android:bottomLeftRadius="20dp"
        android:bottomRightRadius="20dp"
        android:topLeftRadius="20dp"
        android:topRightRadius="20dp" />

</shape>

现在,curve_shap.XML在主视图布局中添加它.就我而言,我已经习惯了LinearLayout

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="80dp"
        android:background="@drawable/curve_shap"
        android:orientation="vertical" >
...
</LinearLayout>

怎么称呼这个？

CustomDialogClass cdd = new CustomDialogClass(MainActivity.this);
cdd.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
cdd.show();

我希望这对你有用.

Answer 2

这是一个示例对话框,使用xml创建.

下一个代码xml只是一个例子,设计或视图在这里实现:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#ffffffff">

<ImageView
    android:layout_width="match_parent"
    android:layout_height="120dp"
    android:id="@+id/a"
    android:gravity="center"
    android:background="#DA5F6A"
    android:src="@drawable/dialog_cross"
    android:scaleType="fitCenter" />

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="TEXTO"
    android:id="@+id/text_dialog"
    android:layout_below="@+id/a"
    android:layout_marginTop="20dp"
    android:layout_marginLeft="4dp"
    android:layout_marginRight="4dp"
    android:layout_marginBottom="20dp"
    android:textSize="18sp"
    android:textColor="#ff000000"
    android:layout_centerHorizontal="true"
    android:gravity="center_horizontal" />

<Button
    android:layout_width="wrap_content"
    android:layout_height="30dp"
    android:text="OK"
    android:id="@+id/btn_dialog"
    android:gravity="center_vertical|center_horizontal"
    android:layout_below="@+id/text_dialog"
    android:layout_marginBottom="20dp"
    android:background="@drawable/btn_flat_red_selector"
    android:layout_centerHorizontal="true"
    android:textColor="#ffffffff" />

</RelativeLayout>

这行代码是drawable的资源:

android:src="@drawable/dialog_cross"
android:background="@drawable/btn_flat_red_selector"

你可以做一个类扩展Dialog,也是这样的:

public class ViewDialog {

    public void showDialog(Activity activity, String msg){
        final Dialog dialog = new Dialog(activity);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        dialog.setCancelable(false);
        dialog.setContentView(R.layout.dialog);

        TextView text = (TextView) dialog.findViewById(R.id.text_dialog);
        text.setText(msg);

        Button dialogButton = (Button) dialog.findViewById(R.id.btn_dialog);
        dialogButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dialog.dismiss();
            }
        });

        dialog.show();

    }
}

最后是你的Activity上的调用形式,例如:

ViewDialog alert = new ViewDialog();
alert.showDialog(getActivity(), "Error de conexión al servidor");

我希望它为你工作.

另一种简单的方法.

步骤1)创建一个具有正确id的布局.

步骤2)在任何您想要的地方使用以下代码.

LayoutInflater factory = LayoutInflater.from(this);
final View deleteDialogView = factory.inflate(R.layout.mylayout, null);
final AlertDialog deleteDialog = new AlertDialog.Builder(this).create();
deleteDialog.setView(deleteDialogView);
deleteDialogView.findViewById(R.id.yes).setOnClickListener(new OnClickListener() {    
    @Override
    public void onClick(View v) {
        //your business logic 
        deleteDialog.dismiss();
    }
});
deleteDialogView.findViewById(R.id.no).setOnClickListener(new OnClickListener() {    
    @Override
    public void onClick(View v) {
        deleteDialog.dismiss();    
    }
});

deleteDialog.show();

Answer 4

添加以下主题 values -> style.xml

<style name="Theme_Dialog" parent="android:Theme.Light">
     <item name="android:windowNoTitle">true</item>
     <item name="android:windowBackground">@android:color/transparent</item>
</style>

在您的onCreateDialog方法中使用此主题,如下所示:

Dialog dialog = new Dialog(FlightBookActivity.this,R.style.Theme_Dialog);

在xml文件中定义包含标题栏的对话框布局,并将xml文件设置为:

dialog.setContentView(R.layout.your_dialog_layout);

Answer 5

简单首先创建一个类

 public class ViewDialog {

        public void showDialog(Activity activity, String msg){
            final Dialog dialog = new Dialog(activity);
            dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
            dialog.setCancelable(false);
            dialog.setContentView(R.layout.custom_dialogbox_otp);
            dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));

            TextView text = (TextView) dialog.findViewById(R.id.txt_file_path);
            text.setText(msg);

            Button dialogBtn_cancel = (Button) dialog.findViewById(R.id.btn_cancel);
            dialogBtn_cancel.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
//                    Toast.makeText(getApplicationContext(),"Cancel" ,Toast.LENGTH_SHORT).show();
                    dialog.dismiss();
                }
            });

            Button dialogBtn_okay = (Button) dialog.findViewById(R.id.btn_okay);
            dialogBtn_okay.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
//                    Toast.makeText(getApplicationContext(),"Okay" ,Toast.LENGTH_SHORT).show();
                    dialog.cancel();
                }
            });

            dialog.show();
        }
    }

然后创建custom_dialogbox_otp

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="330dp"
    android:layout_height="160dp"
    android:background="#00555555"
    android:orientation="vertical"
    android:padding="5dp"
    android:weightSum="100">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@drawable/round_layout_otp"
        android:orientation="vertical"
        android:padding="7dp"
        android:weightSum="100">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_weight="60"
            android:orientation="horizontal"
            android:weightSum="100">

            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:layout_weight="80"
                android:gravity="center">

                <ImageView
                    android:id="@+id/a"
                    android:layout_width="50dp"
                    android:layout_height="50dp"
                    android:background="#DA5F6A"
                    android:gravity="center"
                    android:scaleType="fitCenter"
                    android:src="@mipmap/infoonetwo" />

            </LinearLayout>

            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:layout_weight="20">

                <TextView
                    android:id="@+id/txt_file_path"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_gravity="center"
                    android:singleLine="true"
                    android:text="TEXTO"
                    android:textColor="#FFFFFF"
                    android:textSize="17sp"
                    android:textStyle="bold" />
            </LinearLayout>
        </LinearLayout>

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_weight="40"
            android:background="@drawable/round_layout_white_otp"
            android:orientation="vertical"
            android:weightSum="100">

            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:layout_gravity="center"
                android:layout_weight="60">

                <TextView
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:gravity="center"
                    android:text="Do you wanna Exit..?"
                    android:textColor="#ff000000"
                    android:textSize="15dp"
                    android:textStyle="bold" />
            </LinearLayout>

            <LinearLayout
                android:layout_width="match_parent"

                <LinearLayout

                    android:layout_height="match_parent"
                    android:layout_marginRight="30dp"
                    android:layout_weight="50"
                    android:gravity="center|right">

                    <Button
                        android:id="@+id/btn_cancel"
                        android:layout_width="80dp"
                        android:layout_height="25dp"

                        android:text="CANCEL"
                        android:textSize="13dp"
                        android:textStyle="bold"
                        android:textColor="#ffffffff" />

                </LinearLayout>

                <LinearLayout
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:layout_marginLeft="30dp"
                    android:layout_weight="50"
                    android:gravity="center|left">


                    <Button
                        android:id="@+id/btn_okay"
                        android:layout_width="80dp"
                        android:layout_height="25dp"
                        android:background="@drawable/round_button"
                        android:text="OKAY"
                        android:textSize="13dp"
                        android:textStyle="bold"
                        android:textColor="#ffffffff" />

                </LinearLayout>
            </LinearLayout>
        </LinearLayout>
    </LinearLayout>
</LinearLayout>

然后在你的drawable创建xml文件下面.
对于round_layout_white_otp.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >

    <!-- <corners android:radius="10dp" /> -->
    <corners
        android:bottomLeftRadius="18dp"
        android:bottomRightRadius="16dp"
        android:topLeftRadius="38dp"
        android:topRightRadius="36dp" />
    <solid android:color="#C0C0C0" />
    </shape>

对于round_layout_otp.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >

    <!-- <corners android:radius="10dp" /> -->
    <corners
        android:bottomLeftRadius="18dp"
        android:bottomRightRadius="16dp"
        android:topLeftRadius="38dp"
        android:topRightRadius="38dp" />
    <solid android:color="#DA5F6A" />
    </shape>

round_button

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >

    <!-- <corners android:radius="10dp" /> -->
    <corners
        android:bottomLeftRadius="7dp"
        android:bottomRightRadius="7dp"
        android:topLeftRadius="7dp"
        android:topRightRadius="7dp" />
    <solid android:color="#06A19E" />
    </shape>

然后最后使用下面的代码来视觉对话:)

ViewDialog alert = new ViewDialog();
        alert.showDialog(ReceivingOTPRegActivity.this, "OTP has been sent to your Mail ");

你的输出:)

        txt_desc.setText(desc);
        txt_startDate.setText(fromDate + "\t to \t" + toDate);
        txt_resions.setText(resions);



        btn_accept = (Button) view.findViewById(R.id.btn_dialog_accept);
        btn_reject = (Button) view.findViewById(R.id.btn_dialog_reject);

创建自定义对话框的最简单方法:

1. 初始化并显示对话框:

    ViewDialog alertDialoge = new ViewDialog();
    alertDialoge.showDialog(getActivity(), "PUT DIALOG TITLE");
   

2. 创建方法:

   public class ViewDialog {
   
     public void showDialog(Activity activity, String msg) {
   
       final Dialog dialog = new Dialog(activity);
       dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
       dialog.setCancelable(false);
       dialog.setContentView(R.layout.custom_dialoge_feedback);
   
       TextView text = (TextView) dialog.findViewById(R.id.text_dialog_feedback);
       text.setText(msg);
   
       Button okButton = (Button) dialog.findViewById(R.id.btn_dialog_feedback);
       Button cancleButton = (Button) dialog.findViewById(R.id.btn_dialog_cancle_feedback);
       final EditText edittext_tv = (EditText) dialog.findViewById(R.id.dialoge_alert_text_feedback);
   
       okButton.setOnClickListener(new View.OnClickListener() {
   
           @Override
           public void onClick(View v) {
               //Perfome Action
           }
       });
       cancleButton.setOnClickListener(new View.OnClickListener() {
           @Override
           public void onClick(View view) {
               dialog.dismiss();
           }
       });
   
       dialog.show();
   
       }
   }

这是创建自定义对话框的非常简单的方法。

对话框.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical">
<!--  Put your layout content  -->
</LinearLayout>

MainActivity.java

ShowPopup(){
LayoutInflater li = LayoutInflater.from(this);
View promptsView = li.inflate(R.layout.dialog, null);
android.app.AlertDialog.Builder alertDialogBuilder = new 
android.app.AlertDialog.Builder(this);
alertDialogBuilder.setView(promptsView);
alertDialogBuilder.setCancelable(true);
AlertDialog alertDialog = alertDialogBuilder.create();
alertDialog.show();
}

创建自定义警报布局 custom_aler_update.xml

然后将此代码复制到 Activity ：

AlertDialog basic_reg;
AlertDialog.Builder builder ;
builder = new AlertDialog.Builder(ct, R.style.AppCompatAlertDialogStyle);
LayoutInflater inflater = ((Activity) ct).getLayoutInflater();
View v = inflater.inflate(R.layout.custom_aler_update, null);
builder.setView(v);
builder.setCancelable(false);
builder.create();
basic_reg = builder.show();

将此代码复制到样式：

<style name="AppCompatAlertDialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
    <item name="colorAccent">@color/colorAccent</item>
    <item name="android:textColorPrimary">@color/primaryTextColor</item>
    <item name="android:background">@color/white</item>
</style>

Answer 10

我发现这是显示自定义对话框的最简单方法。

你有布局 your_layout.xml

public void showCustomDialog(final Context context) {
    Dialog dialog = new Dialog(context);
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    view = inflater.inflate(R.layout.your_layout, null, false);
    findByIds(view);  /*HERE YOU CAN FIND YOU IDS AND SET TEXTS OR BUTTONS*/
    ((Activity) context).getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE | WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
    dialog.setContentView(view);
    final Window window = dialog.getWindow();
    window.setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.WRAP_CONTENT);
    window.setBackgroundDrawableResource(R.color.colorTransparent);
    window.setGravity(Gravity.CENTER);
    dialog.show();
}
