示例代码

View decorView = getWindow().getDecorView();

// Hide both the navigation bar and the status bar.

// SYSTEM_UI_FLAG_FULLSCREEN is only available on Android 4.1 and higher, but as

// a general rule, you should design your app to hide the status bar whenever you

// hide the navigation bar.

int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION

| View.SYSTEM_UI_FLAG_FULLSCREEN;

decorView.setSystemUiVisibility(uiOptions);

但是,有个问题。

这样的确能隐藏底部虚拟导航栏,但是一旦你点击屏幕,导航栏会出现(持续1秒左右),并且消费掉你的点击事件。如果你要点击一个按钮(导航栏隐藏状态下),你需要连续点两次。因为1秒钟之后,导航栏又消失了,点击屏幕事件会被再次拦截消费。

最终的解决方案

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);

}

}
