我如何改变默认对话框按钮的文本颜色在安卓5

我有很多警报对话框在我的应用程序。这是一个默认的布局，但我添加了积极和消极的按钮对话框。所以按钮得到Android 5的默认文本颜色(绿色)。我试图改变它，但没有成功。知道怎么改变文字的颜色吗?

自定义对话框:

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();

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

非常感谢

快速简单的方法: 更改res/values/colors.xml中的colorAccent颜色，颜色以十六进制表示，例如#010613为黑色。拜拜

按钮和其他文本的颜色也可以通过主题来改变:

values-21 / styles.xml

<style name="AppTheme" parent="...">
  ...
  <item name="android:timePickerDialogTheme">@style/AlertDialogCustom</item>
  <item name="android:datePickerDialogTheme">@style/AlertDialogCustom</item>
  <item name="android:alertDialogTheme">@style/AlertDialogCustom</item>
</style>

<style name="AlertDialogCustom" parent="android:Theme.Material.Light.Dialog.Alert">
  <item name="android:colorPrimary">#00397F</item>
  <item name="android:colorAccent">#0AAEEF</item>
</style>

结果:

In your app's theme/style, add the following lines: <item name="android:buttonBarNegativeButtonStyle">@style/NegativeButtonStyle</item> <item name="android:buttonBarPositiveButtonStyle">@style/PositiveButtonStyle</item> <item name="android:buttonBarNeutralButtonStyle">@style/NeutralButtonStyle</item> Then add the following styles: <style name="NegativeButtonStyle" parent="Widget.MaterialComponents.Button.TextButton.Dialog"> <item name="android:textColor">@color/red</item> </style> <style name="PositiveButtonStyle" parent="Widget.MaterialComponents.Button.TextButton.Dialog"> <item name="android:textColor">@color/red</item> </style> <style name="NeutralButtonStyle" parent="Widget.MaterialComponents.Button.TextButton.Dialog"> <item name="android:textColor">#00f</item> </style>

使用此方法无需在AlertDialog构建器中设置主题。

这是一个自定义主题，以改变AlertDialog按钮的textColor。它在我的设备上工作-三星ga70 -安卓11

<style name="AlertDialogCustom" parent="Theme.AppCompat.Light.Dialog.Alert">
    <!--Support for other devices, I think so-->
        <item name="android:textColor">@color/yourcolor</item>
        <item name="colorButtonNormal">@color/yourcolor</item>
        <item name="colorAccent">@color/yourcolor</item>
    <!--only this code works on my device-->
        <item name="buttonBarButtonStyle">@style/MyButtonStyle</item>
    </style>

    <!--only this code works on my device-->
    <style name="MyButtonStyle" parent="Widget.AppCompat.Button.Borderless">
        <item name="android:textColor">@color/yourcolor</item>
    </style>

使用styles.xml (value)

非常简单的解决方案，改变colorPrimary作为您的选择，它将改变按钮文本的警告框的颜色。

<style name="MyAlertDialogStyle" parent="android:Theme.Material.Dialog.Alert">


        <!-- Used for the buttons -->
        <item name="colorAccent">@android:color/white</item>
        <!-- Used for the title and text -->
        <item name="android:textColorPrimary">@color/black</item>

        <!-- Used for the background -->
        <item name="android:background">#ffffff</item>
        <item name="android:colorPrimary">@color/white</item>
        <item name="android:colorAccent">@color/white</item>
        <item name="android:windowEnterAnimation">@anim/bottom_left_enter</item>
    </style>

替代方案(使用Java)

 @SuppressLint("ResourceAsColor")
            public boolean onJsAlert(WebView view, String url, String message, final JsResult result) {

                AlertDialog dialog = new AlertDialog.Builder(view.getContext(), R.style.MyAlertDialogStyle)

                        .setTitle("Royal Frolics")
                        .setIcon(R.mipmap.ic_launcher)
                        .setMessage(message)
                        .setPositiveButton("OK", (dialog1, which) -> {
                            //do nothing
                            result.confirm();
                        }).create();

                Objects.requireNonNull(dialog.getWindow()).getAttributes().windowAnimations = R.style.MyAlertDialogStyle;
                dialog.show();
                
                dialog.getButton(AlertDialog.BUTTON_POSITIVE).setTextColor(R.color.white);
                return true;

            }

最简单的解决方案是:

dialog.show(); //Only after .show() was called
dialog.getButton(AlertDialog.BUTTON_NEGATIVE).setTextColor(neededColor);
dialog.getButton(AlertDialog.BUTTON_POSITIVE).setTextColor(neededColor);
