我可以创建并显示一个自定义警报对话框,但即便如此,我android:layout_width/height="fill_parent"在对话框xml中它只有内容一样大.

我想要的是填充整个屏幕的对话框,除了20像素的填充.然后,作为对话框一部分的图像将使用fill_parent自动拉伸到完整的对话框大小.

您好我正在使用Android应用程序,我用它DialogFragment来显示对话框,但它的宽度非常小.我怎样才能达到这个宽度fill_parent呢？

public class AddNoteDialogFragment extends DialogFragment {

    public AddNoteDialogFragment() {
        // Empty constructor required for DialogFragment
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        getDialog().setTitle(getString(R.string.app_name));
        View view = inflater.inflate(R.layout.fragment_add_note_dialog,
                container);

        return view;
    }


    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        Dialog dialog = super.onCreateDialog(savedInstanceState);

        // request a window without the title
        dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);

        return dialog;
    }
}

fragment_add_note_dialog.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="match_parent"
    android:background="@android:color/white"
    android:orientation="vertical"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin" >

    <EditText
        android:id="@+id/addNoteEditText"
        android:layout_width="match_parent" …

我似乎无法控制对话框的宽度.我有一个像这样简单的布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:theme="@android:style/Theme.Dialog"> 

    <ScrollView 
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent">
        <LinearLayout     android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent">

        <TextView 
            android:id="@+id/name_prompt_view"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="@string/name_prompt"
            android:padding="10dip"/>

        <EditText 
            android:id="@+id/name_inp" 
            android:layout_width="fill_parent" 
            android:layout_height="wrap_content" 
            android:lines="1"
            android:maxLines="1"
            android:maxLength="48"
            android:inputType="text" />

        <TextView 
            android:id="@+id/t1_prompt_view"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="@string/t1_prompt"
            android:padding="10dip"/>

        <Spinner 
            android:id="@+id/t1_inp" 
            android:layout_width="fill_parent" 
            android:layout_height="wrap_content" 
            android:lines="1"
            android:maxLines="1"
            android:maxLength="48"
            android:inputType="text"
            android:singleLine="true"
            android:layout_weight="1"
            android:entries= "@array/t1_allowed_values" />

         </LinearLayout>

    </ScrollView>

</LinearLayout>

由于某种原因,对话框只有足够宽的文本输入字段大约11个字符宽.如何使对话框宽度填满屏幕？

在我的应用程序中,我创建的自定义对话框没有完整的高度,我无法更改和自定义.例如看到这个屏幕截图:

我的代码:

final Dialog contacts_dialog = new Dialog(ActivityGroup.this, R.style.theme_sms_receive_dialog);
contacts_dialog.setContentView(R.layout.dialog_schedule_date_time);
contacts_dialog.setCancelable(true);
contacts_dialog.setCanceledOnTouchOutside(true);
contacts_dialog.show();

布局:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/layoutRoot"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@null"
    android:orientation="vertical" >

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/shape_header_dialog_background"
        android:orientation="horizontal"
        android:padding="4dp" >

        <TextView
            android:id="@+id/TextView21"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:layout_marginRight="5dp"
            android:layout_weight="2"
            android:gravity="center_vertical|right"
            android:text="@string/choose_schedule_time_date"
            android:textColor="#ffffff"
            android:textSize="14sp"
            android:textStyle="bold" />

        <ImageView
            android:id="@+id/ImageView03"
            android:layout_width="50dp"
            android:layout_height="50dp"
            android:layout_marginTop="0dp"
            android:background="@drawable/icon_scudule_time" />
    </LinearLayout>

</LinearLayout>

样式:

<style name="theme_sms_receive_dialog" parent="android:style/Theme.Dialog">
    <item name="android:windowNoTitle">true</item>
    <item name="android:background">@android:color/transparent</item>
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="numberPickerStyle">@style/NPWidget.Holo.Light.NumberPicker</item>
</style>
