For case: you have multiple buttons and you want make selected only one button. In parent (NOT ROOT, just parent of child) of buttons, in its xml params add
android:splitMotionEvents="false"
And that's it.
Example:
Btw. When you have 2 linearlayout with 3 buttons per layout, you should set this splitMotionEvents in that two layouts and also in parent of that 2 linearLayouts. Otherwise you will be able click only one button per layout (sum = 2 then). I hope you get it. :)
None of the other solutions didn't work for me or was too lame.
