MultiAutoCompleteTextView 不调用 onFocusChanged()

MultiAutoCompleteTextView does not invoke onFocusChanged()

当点击 MultiAutoCompleteTextView 并获得焦点时需要做一些事情,但似乎没有调用侦听器。知道为什么吗?这是代码:

searchbar.setOnFocusChangeListener(new View.OnFocusChangeListener() {
        @Override
        public void onFocusChange(View view, boolean b) {
            if(b) hide();
            else Utils.closeKeyboard(MapsActivity_v2.this, view);
        }
    });

<MultiAutoCompleteTextView
                android:imeOptions="actionDone"
                android:id="@+id/searchbar"
                android:focusable="true"
                android:focusableInTouchMode="true"
                android:background="@android:color/transparent"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:hint="@string/search_hint"
                android:padding="6dp"/>

加入XML:

android:focusable="true"
android:focusableInTouchMode="true"

代码运行正常。
