Android 全屏时dialog中弹出edittext，输入法弹出后不自动隐藏导航栏Navigation

• 在activity中复写onWindowFocusChanged方法

    @Override
    public void onWindowFocusChanged(boolean hasFocus) {
        super.onWindowFocusChanged(hasFocus);
        hideNavigationBar();
    }

• hideNavigationBar()方法隐藏Navigationbar

  //隐藏导航栏
      private void hideNavigationBar() {
          View decorView = getWindow().getDecorView();
          int uiOptions =
                  View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                          | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                          | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                          | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                          | View.SYSTEM_UI_FLAG_FULLSCREEN
                          | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;
          decorView.setSystemUiVisibility(uiOptions);
      }
