ANDROID: Highlight/Select with Trackball and when Touched

Question

My Android application currently has TableLayout with several TableRows containing an ImageView then TextView side-by-side.

Clicking any where on a TableRow will load a new activity showing further info.

If I use the trackball, it will work its way through the rows, but I don't see which is currently selected so have no idea which TableRow is selected when I click the button to load the activity.

Likewise, when a user touches the screen with a finger, there is no highlight showing which one they selected.

I've searched with terms such as Highlight, Selected, Focus, but none of the pages I see returned have given me any insight into achieving what I require.

Using a TableLayout is required I guess, it was just what I used and may not even be the best solution!

Any examples out there I can try to get this working??

Thanks! :)

Answer 1

You need to use selectors, for instance you have some view which holds view of you row, then you need to create selector like this

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_focused="true" android:drawable="@drawable/list_viewentry_focused" />
    <item android:state_pressed="true" android:drawable="@drawable/list_viewentry_pressed" />
    <item android:drawable="@drawable/list_viewentry_normal" />
</selector>

and put it in your drawables folder

then you need to set android:background @drawable/drawable_name
