Question

i try to work with spinner on dialog

public class data extends Dialog {
.
.
.
String[] iType = { "AA","BB","CC" };
public Spinner TypeSelect;

public void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     setContentView(R.layout.data);
     setTitle("My Heder");

     TypeSelect = (Spinner) findViewById(R.id.spinner2);
     ArrayAdapter<String> TypeAdapter = new ArrayAdapter<String>(this,
       android.R.layout.simple_spinner_item,iType);
        TypeSelect.setAdapter(TypeAdapter);

but i got error on this line:

 ArrayAdapter<String> TypeAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item,iType);

the error:

The constructor ArrayAdapter<String>(data, int, String[]) is undefined

what can be the problem ?

Answer 1

Dialog isn’t a sub-class of Context so you can’t use this in the following…

ArrayAdapter<String> TypeAdapter = new ArrayAdapter<String>(this,
    android.R.layout.simple_spinner_item,iType);

Try using getContext() instead of this.
