mainactivity.class

package org.me.dailogfrmchildact;


public class MainActivity extends Activity {

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);

        /** Display Custom Dialog */
        CustomizeDialog customizeDialog = new CustomizeDialog(this);
        customizeDialog.show();
// ToDo add your GUI initialization code here        
    }

}

You can't just call setListAdapter in a Dialog because this is a method of Activity. But what you should do is create a ListView in your layout (right now it is called main) and assign it an id:

<ListView
android:id="@+id/list"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>

Now you can find your ListView in the code and set an adapter for it:

ListView list = (ListView) findViewById(R.id.list);
list.setAdapter(new ListViewAdapter(this));

As far as I know, SetListAdapter is a method of the class ListView. So you have to be extending listActivity, or call it from an object of listview

I solved the question, here is the answer. Follow the first answer to create a listview with name as usual.

public CustomizeDialog(Context context) {
        super(context);

// access the context again...


final Context cs=context;

//then use this "cs" to set the adapter...


list.setAdapter(new ListViewAdapter(cs));


//...
}
