Android datepicker dialog set background color fails

Question

I have the following date picker

        DatePickerDialog dialog = new DatePickerDialog(
            ctx,
            R.style.DatePicker,
            new DatePickerDialog.OnDateSetListener() {
                @Override
                public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
                    .....dostuff
                }
            },
            year, month, day);

    dialog.show();

In my styles i have setup

    <style name="DatePicker" parent="Theme.AppCompat.Light.Dialog">
       <item name="colorPrimary">@color/primary</item>
      <item name="colorPrimaryDark">@color/primary_dark</item>
       <item name="colorAccent">@color/primary</item>
    </style>

And my colors

    <color name="colorPrimary">#3fb55b</color>
<color name="colorPrimaryDark">#FF247038</color>
<color name="colorAccent">#ece9ea</color>
<color name="colorBackground">#238927</color>

But whenever i show the datepicker it always shows a white background as in the following screenshot

What else do i need to add for the green background to show

Answer 1

Add this lines to your style.xml file

<style name="DialogTheme" parent="Theme.AppCompat.Light.Dialog.Alert">
    <item name="android:background">#000 <!--add you backgroud color here --> </item> 
</style>

Then :

DatePickerDialog dialog = new DatePickerDialog(
            ctx,
            R.style.DialogTheme,
            new DatePickerDialog.OnDateSetListener() {
                @Override
                public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
                    .....dostuff
                }
            },
            year, month, day);

    dialog.show();

Hope this helps

您使用下面的代码更改datepickerdialog背景：

    <style name="datePicker">
    <item name="android:background">@color/custColtransparante</item>
</style>

然后用于将样式设置为datepicker：

private void showDatePicker() {

   Calendar cal = Calendar.getInstance();
    int day = cal.get(Calendar.DAY_OF_MONTH);
    int month = cal.get(Calendar.MONTH);
    int year = cal.get(Calendar.YEAR);

  DatePickerDialog  datePicker = new DatePickerDialog(this, R.style.Snackbar,new DatePickerDialog.OnDateSetListener() {
        @Override
        public void onDateSet(DatePicker view, int mYear, int mMonth, int mDayOfMonth) {
            Log.d("Rail", "Year-" + mYear);
            Log.d("Rail", "Month-" + mMonth);
            Log.d("Rail", "Day-" + mDayOfMonth);
            String dateto = "" + mDayOfMonth + "/" + mMonth + "/" + mYear;
            textView.setText(dateto);

        }
    }, year, month, day);
    datePicker.show();
}
