Android custom ListView with ImageButton is not getting focus

I am developing an app for android TV. I have a listview with an ImageButton + Textviews as children. As TV does not take touch events but uses D-PAD or trackball remote I have to get focus on all clickable items so that user knows where the focus is. But the problem is I can get focus on list row if I add

android:descendantFocusability="blocksDescendants"

in the custom list row layout but ImageButton in the list row will not get focus. And if I remove above code then ImageButton gets focus but I can't click list row.

Also I added setItemsCanFocus for my ListView but no luck, nothing changed. I read many documents but i could not find a proper answer for this problem. I want focus on both List row as well as ImageButton. Is it possible, if any one knows please help me...

View getting hang up due to multiple views inside row file, to get click You have to add one more property to your main layout of row xml.

android:descendantFocusability="blocksDescendants

But when I write above property then I'm not able to focus ImageButton which is in my row file.

I just tried one way to acheive to get foucus on ImageButton as well as on listview.

To get focus on ImageButton:

1. Create one selector file.
2. Applied on Imagebutton.
3. Added android:focusableInTouchMode="true" to ImageButton.

To get focus on Listview:

1. Add android:descendantFocusability="blocksDescendants to main-layout within row xml.

Now when you click on your ImageButton it will focus with your desire color even it will focus on listview click too.

Selecotor.xml

<?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/transparent" 
        /> <!-- pressed -->    
    <item 
        android:state_focused="true"
        android:drawable="@android:color/darker_gray" 
        /> <!-- focused -->    
    <item 
        android:drawable="@android:drawable/btn_star" 
        /> <!-- default -->
</selector>

Tested in S3 emulator, works well.
