Answer 1

viewToLoad = getLayoutInflater().inflate(R.layout.line_discount, null);
(viewToLoad.getContext(), android.R.layout.simple_spinner_item, proList); adapter.setDropDownViewResource(android.R.layout.simple_spinner_item);

This did the job for me

Answer 2

I tried with code.Its working fine:

 View viewToLoad;
 @Override
 public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    viewToLoad = LayoutInflater.from(getDialogContext(this)).inflate(R.layout.header_discount, null);
    this.setContentView(viewToLoad); 

     ArrayAdapter<String> adapter = new ArrayAdapter<String> (viewToLoad.getContext(), android.R.layout.simple_spinner_item, proList);
     adapter.setDropDownViewResource(android.R.layout.simple_spinner_item);
     headerDisProdCode.setAdapter(adapter);

     headerDisProdCode.setOnItemSelectedListener(new OnItemSelectedListener() {
        public void onItemSelected(AdapterView<?> parent, View view,int arg2, long arg3) {
            seletcedProductName = parent.getSelectedItem().toString();
            seletcedProductCode = (products.get((int) headerDisProdCode.getSelectedItemId())).getProductCode();

        }

        public void onNothingSelected(AdapterView<?> arg0) {

        }
    });

}

ArrayAdapter context I gave like : viewToLoad.getContext() viewToLoad is the inflate

Answer 3

I had this problem as well, but with Fragments, when adding a fragment to a view, and the answer for me was to pass in getApplicationContext(), but I had to do it through a separate method after instantiating the fragment, since it was requiring the use of a Bundle.

I also had to do the following when inflating the view, using the context passed in above:

View v = inflater.from(context).inflate(R.layout.layout_name, ViewGroup container, T/F);

rather than just:

View v = inflater.from(context).inflate(R.layout.layout_name, ViewGroup container, T/F);

Hope this helps somebody struggling with Fragments.

Answer 4

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);

Answer 5

It's obvious from the error message that the problem is with context used for creating the spinner. Try this

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

Or:

viewToLoad = getLayoutInflater().inflate(R.layout.line_discount, null);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, 
                        android.R.layout.simple_spinner_item, proList);
sp.setAdapter(adapter);

Answer 6

When you create your ArrayAdapter you should pass the Context of your ActivityGroup not the Context of your current Activity.

Here is an example of how I get it:

  public class MyActivityGroup extends ActivityGroup{
       pulbic static MyActivityGroup sGroup;

       protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            sGroup=this;
            //...
       }
  }

  // Tab Implementation
  //.....
  ArrayAdapter<String> adapter = new ArrayAdapter<String> (
          MyActivityGroup.sGroup, android.R.layout.simple_spinner_item, proList);
