DialogFragment 设置全屏方法

DialogFragment 设置全屏的几种方法。

方法一：

@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setStyle(STYLE_NO_FRAME, android.R.style.Theme_Holo_Light);
    }

方法二

style

1 <style name="style_dialog" parent="android:style/Theme.Dialog">
        <item name="android:windowBackground">@color/white</item>
        <item name="android:windowNoTitle">true</item>
        <item name="android:windowIsFloating">true</item>
        <item name="android:windowContentOverlay">@null</item>
        <item name="android:scrollHorizontally">true</item>
        <!-- Dialog进入及退出动画 -->
        <item name="android:windowAnimationStyle">@style/BottomToTopAnim</item>
    </style>
    
     <style name="BottomToTopAnim" parent="android:Animation">
        <item name="@android:windowEnterAnimation">@anim/bottom_in</item>
        <item name="@android:windowExitAnimation">@anim/bottom_out</item>
    </style>

bottom_in bottom_out 进入进出动画

<?xml version="1.0" encoding="utf-8"?>

<translate
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="300"
    android:fromYDelta="100%p"
    android:toYDelta="0"/>
    
<?xml version="1.0" encoding="utf-8"?>
<translate
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="300"
    android:fromYDelta="0"
    android:toYDelta="100%p"/>

代码

@NonNull
   @Override
   public Dialog onCreateDialog(Bundle savedInstanceState) {
       
       LayoutInflater inflater = getActivity().getLayoutInflater();
       View view = inflater.inflate(R.layout.view, null);

       final Dialog dialog = new Dialog(getActivity(), R.style.style_dialog);
       dialog.setContentView(view);
       dialog.show();

       Window window = dialog.getWindow();
       window.setGravity(Gravity.BOTTOM); //可设置dialog的位置
       window.getDecorView().setPadding(0, 0, 0, 0); //消除边距

       WindowManager.LayoutParams lp = window.getAttributes();
       lp.width = WindowManager.LayoutParams.MATCH_PARENT;   //设置宽度充满屏幕
       lp.height = WindowManager.LayoutParams.WRAP_CONTENT;
       window.setAttributes(lp);
       return dialog;

   }
