I've been trying to solve a problem which i been having for past week , i am trying to a access spinner inside different xml layout, all i want is to access the spinner and add array to the spinner.

This is the code i am using and it doesn't work 

setContentView(R.layout.mainreg);
LinearLayout mainLayout = (LinearLayout)findViewById(R.id.main_layout_id);
View view123 = getLayoutInflater().inflate(R.layout.one2reg, mainLayout,false);

Spinner spin = (Spinner) view123.findViewById(R.id.spinnerproblem);
ArrayAdapter<String> adapter = 
    new ArrayAdapter<String> (this, android.R.layout.simple_spinner_item,items);    

adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spin.setAdapter(adapter);
mainLayout.addView(view123);

  • the problem is i cant access the spinner so i can add "item" array also i can add setOnItemSelectedListener to the spinner . the only problem i could think of is just i cant access the spinner . – ben Aug 16 '12 at 13:14
  • What kind of exception do you see in Logcat? Also it's not clear what's the point of adding a spinner the way you do, why not declare it in your mainreg xml file as child of main_layout_id? – Anton Aug 16 '12 at 13:19
  • i want to do it this way is because i got fragment layout which is linked to three different xml layouts. so in my main class i make the fragments so i can slide throw the pages . now i am facing this problem because the spinner is in different xml layout. many thanks Anton – ben Aug 16 '12 at 13:25
  • you should probably utilize the layout trick instead of messing with controls management in code. See [here](http://developer.android.com/training/improving-layouts/reusing-layouts.html) for details – Anton Aug 16 '12 at 14:01
  • I tried that but it didn't work – ben Aug 16 '12 at 14:50

pass true for attach to root while inflating layout, like this.

View view123 = getLayoutInflater().inflate(R.layout.one2reg, mainLayout,true);

  • Sorry.. i think you should remove the following line. mainLayout.addView(view123); – Chitranshu Asthana Aug 16 '12 at 14:55
