Regarding Button Clicking in android
<p>I have an application in Android 2.3.3. There are few buttons in it. I want a functionality (for the buttons) similar to that of qwerty keyboard, where in when we press a key or a letter, that character will be shown for a fraction of a second, just above the place where that character is present in the keyboard.</p>

<p>Do we have any such kind of properties built in?</p>

<p>If there is no such thing, i am using a background color to my buttons and it's hard to get a note of whether the button is clicked or not. Can we somehow make it visible that the button is clicked.</p>
