android.text.method

Provides classes that monitor or modify keypad input.

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:

// 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());
