如何删除 DatePickerDialog 背景

Question

我想去掉 DatePickerDialog 中多余的背景

这是我的代码

DatePickerDialog dpd = new DatePickerDialog(RegisterActivity.this, android.R.style.Theme_Holo_Dialog, date,
                        myCalendar.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
                        myCalendar.get(Calendar.DAY_OF_MONTH));

Answer 1

您可以像这样覆盖对话框主题：

<style name="TransparentDatePickerDialogTheme" parent="AlertDialog.AppCompat">
    <item name="android:windowBackground">@android:color/transparent</item>
</style>

然后像这样应用主题

DatePickerDialog dpd = new DatePickerDialog(RegisterActivity.this, R.style.TransparentDatePickerDialogTheme, date,
                    myCalendar.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
                    myCalendar.get(Calendar.DAY_OF_MONTH));
