Make RelativeLayout checkable

Question

I try to write my own CheckBox using RelativeLayout with TextView and FrameLayout (with selector on background) inside.

Nik's answer is partially right for me, you need added android.R.attr.state_checkable into the STATE_CHECKABLE array, and set the corresponding lenth (2), or else it fails to work.

private static final int[] CHECKED_STATE_SET = {android.R.attr.state_checked, android.R.attr.state_checkable};

@Override
protected int[] onCreateDrawableState(int extraSpace)
{
    int[] result = super.onCreateDrawableState(extraSpace + CHECKED_STATE_SET.length);
    if(mChecked) mergeDrawableStates(result, CHECKED_STATE_SET);
    return result;
}
