android - EditText doesn't work inside AlertDialog v7 -

i using alertdialog v7 create custom dialog. inside custom view have edittext inputtype "phone|numberpassword". in case when try type text - doesn't work, mean edittext doesn't show changes, new symbols...

here custom view alertdialog:

<linearlayout     android:id="@+id/ll_login_reglayout"     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:orientation="vertical"     android:visibility="visible"     android:paddingright="@dimen/dialog_padding"     android:paddingleft="@dimen/dialog_padding"     xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:app="http://schemas.android.com/apk/res-auto">     <edittext             android:id="@+id/et_p1"             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:inputtype="phone|numberpassword"             /> </linearlayout> 

here example of code inside fragment:

private void showsetpassdialog(){     alertdialog.builder builder = new alertdialog.builder(getactivity());     view dialogview = layoutinflater.from(getactivity()).inflate(r.layout.dialog_register_pass, null);      builder.setview(dialogview);     builder.setpositivebutton(getstring(r.string.text_dialogpsw_btn_ok_password),             new dialoginterface.onclicklistener() {                 @override                 public void onclick(dialoginterface dialog, int which) {                     if (!chb.ischecked()) {                         string mess = getstring(r.string.error_check_dogovor);                         su_tools.showtoast(getactivity(), mess);                         showsetpassdialog();                     } else {                         mmainlayout.setvisibility(view.visible);                     }                 }             });     builder.show(); } 

you need break how set dialog. try this:

alertdialog alert = new alertdialog.builder(this)     .setview(dialogview)     .setpositivebutton(getstring(r.string.text_dialogpsw_btn_ok_password), null)     .create();  alert.setonshowlistener(new dialoginterface.onshowlistener() {     @override    public void onsow(dialoginterface dialoginterface) {        final button button = alert.getbutton(alertdialog.button_positive);        button.setonclicklistener(your code here);    } });  alert.show();
