How to mark a listview item?

Question

I know this has been discussed many times in questions like this question and this one. But I have to say it doesn't work for me.

What I wanted to achieve is to mark a ListView item through my CustomAdapter in a special situation. So, not through the user and click listeners. I have a working solution by setting a background drawable to the convertView.

Now I want to change this and let do a selector the job, which is the cleaner solution. But I can't get it to work. There is no problem to set the behavior for pressing an item and set a different color. But I can't mark it as selected after I pressed the item.

I tried different combinations with my listview_item_selector and listview_selector. And I think, that I have missed something very general. That's why I made a setup just to figure out how to mark an item after it was pressed.

Here's my list_item_selector:

<selector xmlns:android="http://schemas.android.com/apk/res/android"> 
    <item android:state_pressed="true" android:drawable="@android:color/transparent"/>
    <item android:state_selected="true" android:drawable="@android:color/transparent"/>
    <item android:drawable="@drawable/state_normal"/>
</selector>

And my listview_selector setted to the ListView as selector:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true" android:drawable="@drawable/state_pressed"></item>
    <item android:state_selected="true" android:drawable="@drawable/selected_item"/>   
</selector>

As I said state_pressed is working. But state_selected drives me nuts.

At least my layout for the custom items:

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/listview_item"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:background="@drawable/listview_item_selector">

    <TextView 
        android:id="@+id/list_tv1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textColor="#FFFFEE"/>

    <TextView 
        android:id="@+id/list_tv2"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textColor="#FFEEEE"/>
</LinearLayout>

I would appreciate any suggestions.

because you are missing a state, you need to mark the row as activated and have the drawable that indicates the row as selected for the activated state

see my question for an example

Showing the current selection in a listview

then use

listview.setItemChecked(position,true);

Thanks a lot for this! I didn't know about that state and that I have to set the activatedBackgroundIndicator. Saved my day – Steve Benett Sep 19 '13 at 19:02
