android - How to acces EditText value from AlertDialog Builder from another layout? -


i have code in config activity , dialog activated when press add_count textview, problem seems value on get_cont null, maybe because inflater doesn't work right ? (usernames , passwords arraylists)

add_cont.setonclicklistener(new view.onclicklistener() {      @override     public void onclick(view v) {           alertdialog.builder builder = new alertdialog.builder(config.this);          layoutinflater inflater = config.this.getlayoutinflater();          final view dialog_layout = inflater.inflate(r.layout.dialog_add_cont, null);          builder.settitle("add cont.");          builder.setview(inflater.inflate(r.layout.dialog_add_cont, null))          .setpositivebutton(r.string.create_cont, new dialoginterface.onclicklistener() {                @override                public void onclick(dialoginterface dialog, int id) {                    edittext get_cont = (edittext)dialog_layout.findviewbyid(r.id.username);                    edittext get_pass = (edittext)dialog_layout.findviewbyid(r.id.password);                     string test_cont = get_cont.gettext().tostring();                    string text_pass = getpass.gettext().tostring();                     usernames.add(3, get_cont.gettext().tostring());                    passwords.add(3, get_pass.gettext().tostring());                }            })            .setnegativebutton(r.string.cancel_cont, new dialoginterface.onclicklistener() {                public void onclick(dialoginterface dialog, int id) {                   dialog.cancel();                }            });           alertdialog alertdialog = builder.create();          alertdialog.show();      } });

and dialog_add_cont layout looks this:

<linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="wrap_content" android:layout_height="wrap_content">  <edittext     android:id="@+id/username"     android:inputtype="textemailaddress"     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:layout_margintop="16dp"     android:layout_marginleft="4dp"     android:layout_marginright="4dp"     android:layout_marginbottom="4dp"     android:hint="username" />  <edittext     android:id="@+id/password"     android:inputtype="textpassword"     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:layout_margintop="4dp"     android:layout_marginleft="4dp"     android:layout_marginright="4dp"     android:layout_marginbottom="16dp"     android:fontfamily="sans-serif"     android:hint="password"/>

did got code somewhere wrong ?

you inflating dialog_layout , never using since inflating xml again , setting directly dialog.

your code should this:

  alertdialog.builder builder = new alertdialog.builder(config.this);   layoutinflater inflater = configurare.this.getlayoutinflater();   final view dialog_layout = inflater.inflate(r.layout.dialog_add_cont, null);   builder.settitle("add cont.");   builder.setview(dialog_layout) ....

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
