Custom tabs are not responding to pressed state

<?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/tab_profile_pressed_mdpi" />
    <item android:drawable="@drawable/tab_profile_unselected_mdpi" />
</selector>

And how I set them:

((ImageView)tabHost.getTabWidge开发者_JAVA百科t().getChildTabViewAt(i).findViewById(R.id.single_tab_img)).setImageResource(unselected_img[i]);

You need to use setBackgroundResource not setImageResource. State drawables work on the background image, not the foreground image.

I believe you need another xml file that lays out what will happen when the tab is pressed.

Example: tab.xml

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

tab_bg_selected

<?xml version="1.0" encoding="utf-8"?>

<shape xmlns:android="http://schemas.android.com/apk/res/android"
   android:shape="rectangle">
   <gradient android:startColor="#A8A8A8" android:centerColor="#7F7F7F"
        android:endColor="#696969" android:angle="-90" />
</shape>
