List selector state selected not working [ANDROID]

In my app, i am using a list view to show a list of items that have one text and one image, i have added a list selector attribute to list view so that any list item will be clicked its background color will be changed to a different one.The problem is that when the list item is selected listview's row (that is a text view and a image view) background is not changed however state pressed is working fine.How it will work? Any help will be appreciated

Listview

<ListView
android:id="@+id/list"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:choiceMode="singleChoice"
android:divider="@null"
android:dividerHeight="0dp"
android:listSelector="@drawable/nav_lists_selector"
/>

List Selector

 <?xml version="1.0" encoding="utf-8"?>
   <selector xmlns:android="http://schemas.android.com/apk/res/android"   android:exitFadeDuration="@android:integer/config_mediumAnimTime">
    <item android:drawable="@drawable/list_pressed" android:state_pressed="true"/>
    <item android:drawable="@drawable/list_selected" android:state_selected="true" />
</selector>

List Pressed

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
    <solid android:color="@color/clr_list_pressed"/>
</shape>

List Selected

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
    <solid android:color="@color/clr_list_selected"/>
</shape>

Old topic but I run into the same problem. For some strange reason the android:state_selected="true" and android:state_selected="false" are reversed for me.

So what finally worked was:

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

So now the only question is, why I have to use those two values reversed.

EDIT:

Think I find why it behaved strangely. After I added the android:listSelector="@drawable/list_selector" that I used for the listview to the android:background="@drawable/list_selector" listview's item view the android:state_selected="true" and false work normally as one whould expect in the selector.

   <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/list_selector"
        android:orientation="horizontal">

        <....some Textviews....>
    />

    </RelativeLayout>

In onItemclick of Listview you can get the position of selected item

@Override
        public void onItemClick(AdapterView<?> adapter, View arg1, int position, long id) {
                selectedItem = position;
                adapter.notifyDataSetChanged();
        }

And in the getView() method of adapter you can change the color of sleceted item

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    final View view = View.inflate(context, R.layout.item_list, null);

    if (position == selectedItem) {
        // Your desired color
    }

    return view;
}

And using selector try the below code

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

You need add "normal status" in your List Selector

<item android:drawable="@drawable/normal_list_color_or_image" />

You only was added status selected and pressed, but you don't was added normal status.

"Normal status" is when your component don't have received one action.
