This is my code :

   View viewToLoad = LayoutInflater.from(this.getParent()).inflate(R.layout.line_discount, null);
    this.setContentView(viewToLoad); 

   ArrayList<String> productList = new ArrayList<String>();
    int size = products.size()+1;
    String[] proList = new String[size];
    proList[0] = "---Select----";

    for(int i = 1; i< size ;i++){
        productList.add(products.get(i-1).getDescription());
        proList[i] = products.get(i-1).getDescription();
    }

    sp = (Spinner)findViewById(R.id.spProList);
    ArrayAdapter<String> adapter = new ArrayAdapter<String> (LineDiscountActivity.this, android.R.layout.simple_spinner_item, proList);
    sp.setAdapter(adapter);

This is my image:

Problem in TabActivity.Because I have run this part Within the TabActivityGroup. Its was working.When I run this inside the Tab Activity within TabActivityGroup, then its a problem. I have TabActivtyGroup &Within that normal TabActivity.

How can I do in this situation?

Answer 1

I think you have context problem.Try to get context using below method

you can create a new activity and set its theme to dialog theme so that when you start your activity it will display as dialog. For more information about dialog see below post

EDIT2

I found a solution for badTokenExcaption

In your activity's onCreate() method replace the line setContentView(R.layout.XXXXX) by

View viewToLoad = LayoutInflater.from(this.getParent()).inflate(R.layout.XXXXX, null);
this.setContentView(viewToLoad); 

and replace the spinner code by following lines

ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource( this, R.array.medicine_types, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_item);
spDosageType.setAdapter(adapter);
