Android Custom Dialog Display -

my custom dialog layout has 2 edit text fields.

<edittext     android:id="@+id/e2"     android:inputtype="none"     android:longclickable="false"     android:selectallonfocus="true"     android:textisselectable="true" />  <edittext     android:id="@+id/e2"     android:inputtype="none"     android:longclickable="false"     android:selectallonfocus="true"     android:textisselectable="true" /> 

i implement class using onfocuschangelistener.

my idea when click text field, 1 custom popup dialog appears select pre-defined value.

it work correctly have minor problem.

if click editext 1 => dialog apear (i select button dismisses) => click editext 2 => dialig appear (i select button dismisses).

however, if if click editext 1 => dialog appears (i select button dismisses), click on editext 1 again (even many times try), dialog not show (in expectation, should appear whenever click).

my class

public class user_input extends activity implements onfocuschangelistener { @override public void onfocuschange(view v, boolean hasfocus) {      final edittext edt = (edittext) findviewbyid(v.getid());      if (hasfocus) {          final dialog dialog = new dialog(user_input.this);         dialog.setcontentview(r.layout.input_dialog);         dialog.settitle("select number: ");         dialog.show();          btn1 = (button) dialog.findviewbyid(r.id.val1);         btn1.setonclicklistener(new view.onclicklistener() {             @override             public void onclick(view view) {                 edt.settext("1");                 dialog.cancel();             }         });          btn2 = (button) dialog.findviewbyid(r.id.val2);         btn2.setonclicklistener(new view.onclicklistener() {             @override             public void onclick(view view) {                 edt.settext("2");                 dialog.cancel();             }         });       } }
