Question

这很奇怪，我在我的自定义对话框中有一个timePicker，问题是它在某些版本的android上看起来不错但在android 5.0.2中，它会得到这样的黑色背景颜色：

如您所见，时钟背景已更改，但我没有做任何更改。

final Dialog dialog = new Dialog(SabadKharid_s1.this, R.style.DialogStyler2);
            dialog.setContentView(R.layout.dialogtime);

            timePicker = (TimePicker) dialog.findViewById(R.id.timePicker);
            timePicker.setIs24HourView(true);
            WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
            lp.copyFrom(dialog.getWindow().getAttributes());
            lp.width = WindowManager.LayoutParams.MATCH_PARENT;
            lp.height = WindowManager.LayoutParams.WRAP_CONTENT;
            dialog.show();
            dialog.getWindow().setAttributes(lp);

这是我使用的风格：

                <style name="DialogStyler2" parent="Theme.AppCompat.Light.Dialog.Alert">
    <item name="android:windowSoftInputMode">stateUnspecified|adjustPan</item>
    <item name="android:windowNoTitle">true</item>
</style>

如何解决此问题？

Answer 1

你在屏幕上弹出的内容......对话可能有默认主题。尝试为弹出窗口使用自定义主题...它会更改背景颜色或设置弹出窗口的自定义视图，并将布局设置父背景设置为android:background="@andrid:color/transparent"

Answer 2

我想不出您在对话框中使用时间选择器的原因，您可以直接使用Material Time Pickers。

您可以使用它来获得更简单的解决方案。 https://github.com/wdullaer/MaterialDateTimePicker

 TimePickerDialog timePickerDialog = TimePickerDialog.newInstance(
            new TimePickerDialog.OnTimeSetListener() {
                @Override
                public void onTimeSet(RadialPickerLayout view, int hourOfDay, int minute, int second) {
                  //Do your thing
    );
    timePickerDialog.setOnCancelListener(new DialogInterface.OnCancelListener() {
        @Override
        public void onCancel(DialogInterface dialogInterface) {
            //do your thing for cancel event
        }
    });
    timePickerDialog.setAccentColor(ContextCompat.getColor(mContext, R.color.colorPrimary));

    timePickerDialog.show(getFragmentManager(), TAG);

尝试使用TimePickerDialog。

    // Initialize time picker
    Calendar c = Calendar.getInstance();
    int curHour = c.get(Calendar.HOUR_OF_DAY);
    int curMinute = c.get(Calendar.MINUTE);
    boolean is24HourView = true;

    // Construct time picker dialog
    TimePickerDialog dialogTimePicker = new TimePickerDialog(this,
            new TimePickerDialog.OnTimeSetListener() {

                @Override
                public void onTimeSet(TimePicker view, int hourOfDay, int minute) 
                {

                    // Do something 
                }
            }, curHour, curMinute, is24HourView);


    // Show time picker dialog
    dialogTimePicker.setTitle("Time Picker");
    dialogTimePicker.show();

希望这会有所帮助〜
