Android屏蔽手机虚拟按键

方法一

滑动屏幕可以显示

```

protectedvoidhideBottomUIMenu() {

  //隐藏虚拟按键，并且全屏

  if(Build.VERSION.SDK_INT > 11&& Build.VERSION.SDK_INT < 19) { // lower api

    View v = this.getWindow().getDecorView();

    v.setSystemUiVisibility(View.GONE);

  } elseif(Build.VERSION.SDK_INT >= 19) {

    //for new api versions.

    View decorView = getWindow().getDecorView();

    intuiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION

        | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY | View.SYSTEM_UI_FLAG_FULLSCREEN;

    decorView.setSystemUiVisibility(uiOptions);

  }

}

```
