具有透明背景的DialogFragment

Question

我試圖創建一個全屏（但狀態欄必須仍然可見）與自定義透明（與此答案相同https://stackoverflow.com/a/29482234）的對話框，但我的背景是不透明的。

我浪費了2天的時間嘗試所有的解決方案，但它不會工作。我的目標是顯示一個自定義暗色對話框（而不是默認的黑色）。上面的答案看起來像我所需要的，但我無法實現它的工作。有什麼建議麼？

我的代碼：

<style name="CustomDialogTheme2" parent="@android:style/Theme.Dialog"> 
    <item name="android:windowIsFloating">false</item> 
    <item name="android:windowIsTranslucent">true</item> 
    <item name="android:windowBackground">@android:color/transparent</item> 
</style> 

佈局：

<?xml version="1.0" encoding="utf-8"?> 
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:background="#AAFFFFFF"> 

    <RelativeLayout 
     android:id="@+id/dialog_root" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_gravity="center" 
     android:layout_marginLeft="50dp" 
     android:layout_marginRight="50dp" 
     android:background="#CCFF0000" 
     android:padding="16dp"> 

     <Button 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:text="Button" /> 


    </RelativeLayout> 

</FrameLayout> 

DialogFragment：

public class TestDialogFrag extends DialogFragment { 

    public static TestDialogFrag newInstance() { 

     Bundle args = new Bundle(); 

     TestDialogFrag fragment = new TestDialogFrag(); 
     fragment.setArguments(args); 
     return fragment; 
    } 

    @Override 
    public void onCreate(@Nullable Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setStyle(DialogFragment.STYLE_NO_TITLE, R.style.CustomDialogTheme2); 
    } 

    @Nullable 
    @Override 
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { 
     View view = inflater.inflate(R.layout.test_dialog_frag, container, false); 
     return view; 
    } 


}
