Super. OnCreate (savedinstancestate);

Setcontentview (r.layout. Main);

/*find the object by IDs. */

EditText = (edittext) Findviewbyid (r.id. ET);

checkbox = (checkbox) Findviewbyid (r.id. CB);

/* Add a listener to the CheckBox */

Checkbox.setoncheckedchangelistener (new Checkbox.oncheckedchangelistener ()

{

Public void oncheckedchanged (Compoundbutton Buttonview,boolean isChecked)

{

if (Checkbox.ischecked ())

{

/* Show the password*/

Edittext.settransformationmethod (Hidereturnstransformationmethod. GetInstance());
