How to set Ripple effect on a LinearLayout programmatically?

I want to set the background android.R.attr.selectableItemBackground to a LinearLayout. When using XML there are no problems (it works)

<LinearLayout
    android:id="@+id/llMiner"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="?android:attr/selectableItemBackground"
    android:clickable="true" >

... but I have to do this in java code, so I've tried this

llMiner.setClickable(true);
llMiner.setBackgroundResource(android.R.attr.selectableItemBackground);

... and it doesn't work, infact I get a NotFoundException on this second line. So after I've tried this variant thinking that the resource is a Color.

llMiner.setClickable(true);
llMiner.setBackgroundColor(android.R.attr.selectableItemBackground);

This one doesn't launch exception, but... doesn't work (there are no changing of background when pressing, but the state change in pressed as it have to do)... any suggestion?

Solution 1:

You can use this way.

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
    // If we're running on Honeycomb or newer, then we can use the Theme's
    // selectableItemBackground to ensure that the View has a pressed state
    TypedValue outValue = new TypedValue();
    this.getTheme().resolveAttribute(android.R.attr.selectableItemBackground, outValue, true);
    textView.setBackgroundResource(outValue.resourceId);
}
