Android隐藏底部虚拟按键
使用场景:欢迎页 启动页 广告页 展示页...
Google的官方文档是:

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);
}
}
