DatePickerDialog显示带有两个边框 [英] DatePickerDialog displays with two borders

问题描述

我对显示DatePickerDialog有一个疑问。

我想创建带有 HoloDialog主题的日期选择器对话框，如下所示：

  DatePickerDialog dpd = new DatePickerDialog（this，android.R.style.Theme_Holo_Dialog，ReservationDate，2014，1，1）; 
  

然后我将看到以下结果：

如您所见，对话框显示为带有两个边框。 / p>

我想创建一个与此处显示的对话框相同的对话框，但是周围有一个边框。

解决方案

假设我正确理解了您的问题，我想我找到了一种方法。在这里，我们匿名地子类化 DatePickerDialog 来覆盖 onCreate（）并为窗口设置透明背景。

  DatePickerDialog dpd = new DatePickerDialog（this，android.R.style.Theme_Holo_Dialog，
 ReservationDate，2014，1，1）{
 @Override 
 public void onCreate（Bundle savedInstanceState）{
 super.onCreate（savedInstanceState）; 
 getWindow（）。setBackgroundDrawable（new ColorDrawable（Color.TRANSPARENT））; 
} 
};

您也可以使用自定义主题。例如：

 < style name = HoloDialog parent = @ android：style / Theme.Holo.Dialog> ; 
< item name = android：windowBackground> @android：color / transparent< / item> 
< / style> 
  

然后在 DatePickerDialog 中传递构造函数：

  DatePickerDialog dpd = new DatePickerDialog（this，R.style.HoloDialog，
 ReservationDate，2014，1， 1）; 
  

I have a question about DatePickerDialog displaying.

I want to create date picker dialog with "HoloDialog" theme like this:

DatePickerDialog dpd = new DatePickerDialog(this, android.R.style.Theme_Holo_Dialog, reservationDate, 2014, 1, 1);

Then I will see this result:

As you can see, dialog is displayed with "two borders" around.

I want to create the same dialog as displayed here, but with one border around. Is it possible?

解决方案

Assuming I understand your question correctly, I think I found a way. Here, we anonymously subclass DatePickerDialog to override onCreate() and set a transparent background for the window.

DatePickerDialog dpd = new DatePickerDialog(this, android.R.style.Theme_Holo_Dialog,
                                            reservationDate, 2014, 1, 1) {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
    }
};

You could also do this with a custom theme instead. For example:

<style name="HoloDialog" parent="@android:style/Theme.Holo.Dialog">
    <item name="android:windowBackground">@android:color/transparent</item>
</style>

Then pass that in the DatePickerDialog's constructor:

DatePickerDialog dpd = new DatePickerDialog(this, R.style.HoloDialog,
                                            reservationDate, 2014, 1, 1);
