我的应用程序中有很多警报对话框.这是默认布局,但我在对话框中添加正负按钮.因此按钮获得Android 5(绿色)的默认文本颜色.我试图改变它但没有成功.知道如何改变文字颜色吗？

My Custom对话框:

public class MyCustomDialog extends AlertDialog.Builder {

    public MyCustomDialog(Context context,String title,String message) {
        super(context);

        LayoutInflater inflater = (LayoutInflater) context.getSystemService( Context.LAYOUT_INFLATER_SERVICE );
        View viewDialog = inflater.inflate(R.layout.dialog_simple, null, false);

        TextView titleTextView = (TextView)viewDialog.findViewById(R.id.title);
        titleTextView.setText(title);
        TextView messageTextView = (TextView)viewDialog.findViewById(R.id.message);
        messageTextView.setText(message);

        this.setCancelable(false);

        this.setView(viewDialog);

    } }

创建对话框:

MyCustomDialog builder = new MyCustomDialog(getActivity(), "Try Again", errorMessage);
builder.setNegativeButton("OK", new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialogInterface, int i) {
                            ...
                        }
}).show();

negativeButton是一个默认的对话框按钮,采用Android 5 Lollipop的默认绿色.

非常感谢

我想在Android Studio v1.0.0 rc2中将此库导入我的项目:

https://github.com/navasmdc/MaterialDesignLibrary

但有一个问题.当我将此库添加为模块时,会出现此错误:

错误:依赖项MyApplication.libraries:MaterialDesign:项目应用程序未指定解析为APK归档文件,不支持作为编译依赖项.文件:C:\ ADTBundle\StudioWorkspace\MyApplication\libraries\MaterialDesign\build\outputs\apk\MaterialDesign-release-unsigned.apk

什么是解决这个问题的分步指南？或者这个库的gradle依赖是什么？

有谁知道如何覆盖AlertDialog按钮的默认样式？我已经浏览了Android源代码中的主题和样式,并尝试了不同的东西,但我还没有找到一种有效的方法.

我下面的内容适用于更改背景,但对按钮没​​有任何作用.通过清单myTheme应用于整体<application>.(为清楚起见,删除了其他一些项目,但它们仅与标题栏相关.)

<style name="myTheme" parent="android:Theme">
    <item name="android:buttonStyle">@style/customButtonStyle</item>
    <item name="android:alertDialogStyle">@style/dialogAlertTheme</item>
</style>

<style name="dialogAlertTheme" parent="@android:style/Theme.Dialog.Alert">
    <item name="android:fullDark">@drawable/dialog_loading_background</item>
    <item name="android:topDark">@drawable/dialog_alert_top</item>
    <item name="android:centerDark">@drawable/dialog_alert_center</item>
    <item name="android:bottomDark">@drawable/dialog_alert_bottom</item>
    <!-- this last line makes no difference to the buttons -->
    <item name="android:buttonStyle">@style/customButtonStyle</item> 
</style>

有任何想法吗？

我最近将我的应用程序迁移到了Material Design,我用我的警报对话框偶然发现了这个问题:

我正在应用这样的对话框样式:

<item name="android:alertDialogTheme">@style/Theme.AlertDialog</item>

和Theme.AlertDialog看起来像这样:

<style name="Theme.AlertDialog" parent="Base.V14.Theme.AppCompat.Dialog">
    <item name="colorPrimary">@color/theme_primary</item>
    <item name="colorPrimaryDark">@color/theme_primary_dark</item>
    <item name="colorAccent">@color/theme_accent_dark</item>
</style>

这是在我的Kitkat设备上发生的,它在Lollipop上工作正常.你能帮助我摆脱那个外在的背景吗？

我的应用程序扩展Theme.AppCompat.Light,材质样式的对话框显示为白色背景,黑色文本颜色和绿色按钮(旋转器ProgessDialog也是绿色).

我想改变文本的颜色和字体,以及按钮和微调器的颜色.

我该怎么做？

我发现这篇文章,但XML解决方案对我不起作用,其他答案是没有的第三方库ProgressDialog.

谢谢!

在我的应用程序中,我使用Theme.Holo和Theme.Holo.Light没有任何问题.当使用Holo主题并单击DialogPreference/ListPreference时,弹出的对话框也以Holo为主题.对于Holo.Light来说也是如此.但是,当我的自定义主题(来自Holo.Light)设置了PreferencesActivity样式时,所有对话框都以Holo.Light为主题.我想我在主题中缺少某些东西.谁能帮助我？非常感谢!

对于屏幕较小的特定设备，默认情况下警报消息太大，我想将其设置为自定义dp

我的警报是这样的

OnClickListener addNewItemListener = new OnClickListener() {
                public void onClick(View v) {
                    AlertDialog.Builder alert = new AlertDialog.Builder(
                            MyActivity.this);

                    LinearLayout myLayout= new LinearLayout(MyActivity.this);
                    myLayout.setOrientation(LinearLayout.VERTICAL);

                    alert.setTitle(R.string.add_title);
                    alert.setMessage(R.string.add_message);

                    final TextView t1 = new TextView(MyActivity.this);
                    t1.setText("Name");
                    final EditText input1 = new EditText(MyActivity.this);
                    myLayout.addView(t1);
                    myLayout.addView(input1);
                    alert.setView(myLayout);
                    alert.setPositiveButton(R.string.cancel,
                            new DialogInterface.OnClickListener() {
                                public void onClick(DialogInterface dialog,
                                        int whichButton) {
                                }
                            });
                    alert.setNegativeButton(R.string.ok,
                            new DialogInterface.OnClickListener() {
                                public void onClick(DialogInterface dialog,
                                        int whichButton) {
                                    try {
                                        ....
                                    } catch (RuntimeException e) {
                                        Alerts.DatiErrati(MyActivity.this);
                                    }

                                }
                            });
                    alert.show();
                } …

阅读MaterialComponents 主题警报对话框按钮和https://medium.com/@lcdsmao/material-design-custom-alert-dialog-5a9cab3ade11我设置AlertDialog了新材料主题的按钮和文本颜色。

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.MaterialComponents.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>

    <!-- AlertDialog -->
    <item name="materialAlertDialogBodyTextStyle">@style/MaterialAlertDialogTextTheme</item>
    <item name="materialAlertDialogTheme">@style/MaterialAlertDialogButtonsTheme</item>
</style>

<!-- AlertDialog text -->
<style name="MaterialAlertDialogTextTheme" parent="MaterialAlertDialog.MaterialComponents.Body.Text">
    <item name="android:textColor">@color/colorPrimary</item>
    <item name="android:colorAccent">@color/colorPrimary</item>
    <item name="colorAccent">@color/colorPrimaryitem>
    <item name="android:textSize">14sp</item>
    <item name="android:textStyle">bold</item>
</style>

<!-- AlertDialog buttons -->
<style name="MaterialAlertDialogButtonsTheme" parent="ThemeOverlay.MaterialComponents.MaterialAlertDialog">
    <item name="buttonBarPositiveButtonStyle">@style/AlertDialog.Button</item>
    ...

创建AlertDialogFragment使用后

override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
    super.onCreateDialog(savedInstanceState)

    return MaterialAlertDialogBuilder(context!!).apply {
        ...
    }.create()
} …

我通过以下方式主题:

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/primary</item>
    <item name="colorPrimaryDark">@color/primaryDark</item>
    <item name="colorAccent">@color/accent</item>
    <item name="alertDialogTheme">@style/AppTheme.Dialog</item>
</style>

<style name="AppTheme.Dialog" parent="Theme.AppCompat.Dialog.Alert">
    <item name="colorAccent">@color/accent</item>
</style>

但是,当我在我的应用程序中创建AlertDialogs时,它们根本不是主题.其他组件如ActionBar正在正确着色.我错过了什么吗？

我使用的是AppCompat版本com.android.support:appcompat-v7:23.1.1,我的设备安装了Android 4.4.4.
