更改警报对话框的文本颜色 [英] Change text color of alert dialog

问题描述

我有一个弹出窗口，用于在我的应用程序中下载音频说明.我想做的是将默认文本颜色"OK"更改为蓝色.我尝试了一些东西，但是没有用.这是我的代码:

I have a popup for downloading the audio instruction in my app. What I am trying to do is I want to change the default text color of "OK" to blue. I tried something but its not working. Here is my code:

 private void showDownloadPgmPopup() {

    android.app.AlertDialog.Builder builder = new android.app.AlertDialog.Builder(getActivity());
    builder.setTitle("Download instructional audio?");
    builder.setMessage(ParamConstants.AUDIODOWNLOADPERMISSION);
    builder.setNegativeButton("No", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            WwDatabaseHelper.storeSelectedWeekAndDay(getActivity(), mSelectedWeekDataModel);
            goToMoveScreen();
        }
    });
    builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            AndroidDownloadFileByProgressBarActivity.StartAudioAssetDownload(getActivity());

        }

    }).create();
    // change the text color of download instruction ok button


    final android.app.AlertDialog dialog = builder.show();
    dialog.setOnShowListener( new DialogInterface.OnShowListener() {
                                  @Override
                                  public void onShow(DialogInterface arg0) {
                                      dialog.getButton(AlertDialog.BUTTON_POSITIVE).setTextColor(Color.parseColor("#ff5722"));
                                  }
                              });
    dialog.setCanceledOnTouchOutside(false);
    dialog.show();
}

但是这种变化并不能反映出有人能告诉我我做错了吗?

But the change is not reflecting can anyone tell me what i am doing wrong?

推荐答案

您必须在AlertDialog构造函数中提供自定义样式ID:

You have to provide a custom style id in the AlertDialog constructor:

AlertDialog.Builder(Context context, int themeResId)

和样式文件应类似于:

<style name="AlertDialogCustom" parent="Theme.AppCompat.Light.Dialog.Alert">
    <item name="android:colorAccent">#0000FF</item>
</style>
