EditText Get Focus Listener event _edittext get and lose focus action

Today, when you're doing a search box, it's easy to do something after you've got the focus, and it's a simple way to do it, to bind Onfocuschangelistener events, implement Onfocuschange (View V, boolean hasfocus), The second parameter is to determine the focus or lose focus, so that I can achieve the desired effect, the code is as follows:

EditText Searchview = (EditText) Findviewbyid (R.id.search_text); Searchview.setonfocuschangelistener (  New  Android.view.View.        Onfocuschangelistener () {    @Override    publicvoid  Onfocuschange (View V, Boolean Hasfocus) {        if  (hasfocus) {            ////  Here is the processed content        When the focus is received else  {            //  handle content when the focus is lost         }}    );

The text box has the following method of regain focus

Searchview.setfocusable (true); Searchview.setfocusableintouchmode (true); Searchview.requestfocus (); Searchview.clearfocus (); // loss of Focus searchview.requestfocus (); // Get Focus

EditText et = (EditText) Findviewbyid (r.id.et);        Et.clearfocus ();        Et.setfocusable (false);

Searchedit.setontouchlistener (NewOntouchlistener () { PublicBoolean OnTouch (View V, motioneventEvent) {                //TODO auto-generated Method StubSearchedit.setfocusable (true); Searchedit.setfocusableintouchmode (true);                Searchedit.requestfocus (); Intent Intent=NewIntent (Getactivity (), searchactivity.class);                StartActivity (Intent); return false; }        });
