title: Android custom keyboard popup
body: <p>I have a custom android keyboard. On long press popup keyboard is shown how it should. The problem is, when it pops up, the keyboard behind is darkenes.
  How can i disable this, except overriding the default KeyboardView onDraw?</p>
  
  <p>One more thing: how can I make the poped up keyboard buttons selected without pressing on them? In Google keyboard, when you press on a "." key, you just keep moving your finger and it selects the key on the popup. But on the default implementation of KeyboardView, you have to press on the key.</p>
  
  <p>This has been bugging me for a month, hope you can help!</p>
