Android 弹出Dialog时隐藏状态栏和底部导航栏的方法

来源：jb51　　时间：2019/7/3 9:53:31　　对本文有异议

上代码

dialog.getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
dialog.getWindow().getDecorView().setOnSystemUiVisibilityChangeListener(new View.OnSystemUiVisibilityChangeListener() {
     @Override
     public void onSystemUiVisibilityChange(int visibility) {
         int uiOptions = View.SYSTEM_UI_FLAG_LAYOUT_STABLE |
         //布局位于状态栏下方
         View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION |
         //全屏
         View.SYSTEM_UI_FLAG_FULLSCREEN |
         //隐藏导航栏
         View.SYSTEM_UI_FLAG_HIDE_NAVIGATION |
         View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN;
         uiOptions |= 0x00001000;
         dialog.getWindow().getDecorView().setSystemUiVisibility(uiOptions);
     }
});

ps:下面看下Android Dialog弹出时不显示导航栏(沉浸式)

我们的app是全屏沉浸式的，发现activity在设置了全屏后，弹出dialog底部会跳出导航栏虚拟键。具体原因是因为Dialog的Window抢走了焦点，Window 中的 DecorView 状态改变导致了退出。

解决方法，在Dialog中：

private void fullScreenImmersive(View view) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
      int uiOptions = View.SYSTEM_UI_FLAG_LAYOUT_STABLE
        | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
        | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
        | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
        | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
        | View.SYSTEM_UI_FLAG_FULLSCREEN;
      view.setSystemUiVisibility(uiOptions);
    }
  }
 
  @Override
  public void show() {
    this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE, WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE);
    super.show();
    fullScreenImmersive(getWindow().getDecorView());
    this.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE);
  }
