android - 具有背景的 DatePicker

Question

问题是我的日期选择器在日期选择器后面有一个丑陋的白色背景

我只想让那个背景消失

这是我的代码

 public void selectDate(View view) {
    DialogFragment newFragment = new SelectDateFragment();
    newFragment.show(Master_.fragmentManager, "DatePicker");
}

public void populateSetDate(int year, int month, int day) {


        Birthdate.setText(year + "-" + month + "-" + day);

}

public class SelectDateFragment extends DialogFragment implements
        DatePickerDialog.OnDateSetListener {
    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        final Calendar calendar = Calendar.getInstance();
        int yy = calendar.get(Calendar.YEAR);
        int mm = calendar.get(Calendar.MONTH);
        int dd = calendar.get(Calendar.DAY_OF_MONTH);

    DatePickerDialog dialog =new DatePickerDialog(mActivity,R.style.jehadStyle, this, yy, mm, dd);  
    dialog.getDatePicker().setMaxDate(calendar.getTimeInMillis());  

    return dialog ;
    }

    public void onDateSet(DatePicker view, int yy, int mm, int dd) {
        populateSetDate(yy, mm + 1, dd);
    }
}

这是我的风格

 <style name="jehadStyle" parent="@android:style/Theme.Holo.Light.Dialog.NoActionBar">
    <item name="android:textColor">@android:color/black</item>

</style>

Answer 1

dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));

将此添加到您的 DatePickerDialog
