【Android】隐藏底部虚拟按键

Google的官方文档是：

1 View decorView = getWindow().getDecorView();
2 // Hide both the navigation bar and the status bar.
3 // SYSTEM_UI_FLAG_FULLSCREEN is only available on Android 4.1 and higher, but as
4 // a general rule, you should design your app to hide the status bar whenever you
5 // hide the navigation bar.
6 int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
7               | View.SYSTEM_UI_FLAG_FULLSCREEN;
8 decorView.setSystemUiVisibility(uiOptions);　　　　

但是，有个问题。

最终的解决方案

/**
* 隐藏虚拟按键，并且全屏
*/
protected void hideBottomUIMenu() {
//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);
} else if (Build.VERSION.SDK_INT >= 19) {
//for new api versions.
View decorView = getWindow().getDecorView();
int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY | View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);
}
}
