Overview

MultiSpinner is a class with can be used by Android developers that need a spinner widget with multi selection capabilities. When the user touches on the spinner widget a dialog pops up with a checkbox list.

After inserting the widget in your layout add the following code to your activity:

   public class MyActivity extends Activity {
       private MultiSpinner spinner;
       private ArrayAdapter<String> adapter;

       @Override
       protected void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
           setContentView(R.layout.activity_main);
    
           // create spinner list elements
           adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item);
           adapter.add("Item1");
           adapter.add("Item2");
           adapter.add("Item3");
           adapter.add("Item4");
           adapter.add("Item5");
    
           // get spinner and set adapter
           spinner = (MultiSpinner) findViewById(R.id.spinnerMulti);
           spinner.setAdapter(adapter, false, onSelectedListener);
    
           // set initial selection
           boolean[] selectedItems = new boolean[adapter.getCount()];
           selectedItems[1] = true; // select second item
           spinner.setSelected(selectedItems);
       }

       private MultiSpinner.MultiSpinnerListener onSelectedListener = new MultiSpinner.MultiSpinnerListener() {
           public void onItemsSelected(boolean[] selected) {
