In my app I have a dialog (dialog1), containing Listview with an ArrayAdapter having 3 string items. I want to set onItemclickListener() on this list,through which I would be able to start different activities on different item click. Please Help.

解决方案

public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setListAdapter(new ArrayAdapter<String>(this,R.layout.new_service_request,LIST));

    ListView lv=getListView();
    lv.setTextFilterEnabled(true);


    lv.setOnItemClickListener(new OnItemClickListener(){



        @Override
        public void onItemClick(AdapterView<?> parent, View v, 
                int position, long id) {   
            // When clicked, show a toast with the TextView text  
            Toast.makeText(getApplicationContext(), ((TextView) v).getText(), 
                Toast.LENGTH_SHORT).show();   
        //  int ITEM_CLICKED = (int)getSelectedItemId();
            switch(position){
            case 0:
                Intent intent1 = new Intent(New.this, Next.class);
                startActivity(intent1);
                break;
            case 1:
                Intent intent2 = new Intent(New.this, List.class);
                startActivity(intent2);
                break;
            case 2:
                Intent intent3= new Intent(New.this, HotCard.class);
                startActivity(intent3);
                break;
