<p>Provides classes that monitor or modify keypad input.</p>
<p>You can use these classes to modify the type of keypad entry
for your application, or decipher the keypresses entered for your specific
entry method. For example:</p>
<pre>
// Set the text to password display style:
EditText txtView = (EditText)findViewById(R.id.text);
txtView.setTransformationMethod(PasswordTransformationMethod.getInstance());

//Set the input style to numbers, rather than qwerty keyboard style.
txtView.setInputMethod(DigitsInputMethod.getInstance());

// Find out whether the caps lock is on.
// 0 is no, 1 is yes, 2 is caps lock on.
int active = MultiTapInputMethod.getCapsActive(txtView.getText());
</pre>
