When Android EditText gets and loses focus, custom handles the content

When Android's EditText gets/loses focus, it needs to customize some of the processing content to listen to the focus of the EditText object.

In the activity, do the following:

1. Get the EditText object.

2. Add Setonfocuschangelistener () to the acquired object, overriding the method inside.

As follows:

EditText loginpwd = (EditText) Findviewbyid (R.id.edittext);

Edittext.setonfocuschangelistener (New Android.view.View.OnFocusChangeListener () {

@Override

public void Onfocuschange (View V, Boolean hasfocus) {

if (Hasfocus) {

What to do when the focus is given here

} else {

What to do when the focus is lost

}

}

});
