如何实现点击FloatingActionButton以外的view关闭fab的菜单?

Question

我想实现点击FloatingActionButton弹出菜单后,点击FloatingActionButton以外的view关闭FloatingActionButton弹出的菜单,这是我的布局:
<?xml version="1.0" encoding="utf-8"?>

</android.support.v4.widget.DrawerLayout>我试过监听rootview的单击事件,结果无效    View rootView = ((ViewGroup)this.findViewById(android.R.id.content)).getChildAt(0);
    rootView.setOnClickListener(this);
    @Override
    public void onClick(View v){
        //close fab

Answer 1

你通过判断当前焦点是否在这个FloatingActionButton，如果不在了，就关闭菜单private void findCurrentFocusView() {Window window = getActivity().getWindow();if (window != null) {Log.d(TAG, "Window");View rootView = window.getDecorView();if (rootView != null) {Log.d(TAG, "rootView");printFocusId(rootView);}}}private void printFocusId(final View rootView) {if (rootView != null) {Log.d(TAG, "printFocusId");new Thread(new Runnable() {
@Overridepublic void run() {// TODO Auto-generated method stubfor(int i = 0; ; i++){try {View view = rootView.findFocus();if (view != null) {int id = view.getId();Log.d(TAG, "id == " + id);}Thread.sleep(50);} catch (InterruptedException e) {// TODO Auto-generated catch blocke.printStackTrace();}
}}}).start();}}

我的代码:rootView = getWindow().getDecorView();
if(rootView != null){
    rootView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            View v = rootView.findFocus();
            Toast.makeText(activity,"id = "+v.getId(),Toast.LENGTH_SHORT).show();
        }
    });
}
好像并没有起作用,我在onClick里Log.d(),发现并没有打印日志,是我设置的监听器有问题?
