Question

I am having problems defining a ListView with a custom adapter and list item xml layout. The problem is that my ListView is not highlight items when pressed. I am doing the following:

I define a drawable selector xml resource file:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:state_pressed="true" android:drawable="@android:color/holo_orange_light" />
    <item android:state_pressed="false" android:drawable="@android:color/white" />
</selector>

I define an item layout xml file:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:background="@drawable/btn_voice_item" 
     >

    <ImageButton
        android:id="@+id/voiceItemFavorite"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:layout_centerVertical="true"
        android:layout_margin="5dp"
        android:background="@drawable/btn_favorite" />

    <TextView
        android:id="@+id/voiceItemText"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerVertical="true"
        android:layout_margin="5dp"
        android:layout_toRightOf="@+id/voiceItemFavorite"
        android:background="@drawable/btn_voice_item" />

</RelativeLayout>

Finally I wrote code in my custom data adapter to inflate and populate then view.

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    if (convertView == null) {
        LayoutInflater inflater = context.getLayoutInflater();
        convertView = inflater.inflate(R.layout.voice_item, null);
    }
    VoiceItem i = getItem(position);
    TextView t = (TextView) convertView.findViewById(R.id.voiceItemText);
    t.setText(i.toString());
    ImageButton b = (ImageButton) convertView.findViewById(R.id.voiceItemFavorite);
    b.setTag(i);
    b.setSelected(i.favorite);
    b.setOnClickListener(new FavoriteClick());
    return convertView;
}

Everything works except when I press items in the list there is no visual indication of the press. I expect the color of the pressed item’s background to transition to the style defined by my drawable selector.

How can I both have a custom view items and retain styling highlighting of items while pressed?

If android:background="@drawable/btn_voice_item" is solid image so it’ll cover the ListView selector. Here is very detail tutorial about custom ListView selector and item backround
