ListView listSelector seems not working

Question

Using listSelector property to change the list item color whenever user do tap on that, for that i am using

list_selector.xml:

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

    <item
        android:state_selected="true"
        android:state_focused="false"
        android:drawable="@drawable/list_hover" 
        />

    <item 
        android:state_selected="true"
        android:state_pressed="false"
        android:drawable="@drawable/list_hover" />
</selector>

list_normal.xml:

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

list_hover.xml:

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

and finally using list_selector in ListView but seems not working for me don't know why its happening ?

  <ListView 
    android:id="@+id/listView"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"        
    android:listSelector="@drawable/list_selector"/>    

list_adapter.xml:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/LinearLayout1"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="10dp"
    android:background="#ffffff"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/tvName"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignTop="@+id/imageView1"
        android:layout_toRightOf="@+id/imageView1"
        android:textStyle="bold"
        android:maxLines="2"
        android:text="@string/str_list_name"
        android:textColor="@android:color/background_dark"
        android:layout_marginLeft="2dp"
        />

    <ImageView
        android:id="@+id/imageView1"
        android:layout_width="wrap_content"

        android:background="@null"
        android:contentDescription="@null"
        android:src="@drawable/available" />

</RelativeLayout>

Answer 1

Instead of android:state_selected use android:state_enabled in list_selector.xml

Use the correct state according to your requirement..

android:state_pressed

Boolean. "true" if this item should be used when the object is pressed (such as when a button is touched/clicked); "false" if this item should be used in the default, non-pressed state.

android:state_focused

Boolean. "true" if this item should be used when the object is focused (such as when a button is highlighted using the trackball/d-pad); "false" if this item should be used in the default, non-focused state.

android:state_selected

Boolean. "true" if this item should be used when the object is selected (such as when a tab is opened); "false" if this item should be used when the object is not selected.

android:state_enabled

Boolean. "true" if this item should be used when the object is enabled (capable of receiving touch/click events); "false" if it should be used when the object is disabled.

Answer 2

Use the android:state_activated="true" state, instead of the "selected" state. That will work Example

Answer 3

i think the problem is in your list_selector.xml try replace following xml code

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