How to send key event to an edit text in android app
<p>For example, send a backsapce key to the edit text control to remove a charactor or send a char code like 112 to append a charactor in the edittext control programatically.</p>

<p>Actually I need a method like</p>

<pre><code>onKeyReceived(int keyCode)
{

// EditText to append the keyCode, I know how to add a visible charator, but what about some special keys, like arrow key, backspace key.

}
</code></pre>
