Android save Checkbox State in ListView with Cursor Adapter

by

I had the same issue myself: how to toggle multiple select CheckedTextView in a custom layout (i.e not using android.R.layout.simple_list_item_multiple_choice)

The following worked for me. The example I have is a custom view that is provided an adaptor extended from SimpleCursorAdapter.

My custom view (row_contact.xml):

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_height="wrap_content" android:layout_width="fill_parent">

  <CheckedTextView
    android:id="@android:id/text1"
    android:layout_width="fill_parent"
    android:layout_height="?android:attr/listPreferredItemHeight"
    android:textAppearance="?android:attr/textAppearanceLarge"
    android:gravity="center_vertical"
    android:paddingLeft="6dip"
    android:paddingRight="6dip" 
    android:checkMark="?android:attr/listChoiceIndicatorMultiple"
    />

  <TextView
    android:text="@+id/TextView01"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/tvNumber"
    android:layout_gravity="bottom" 
    android:paddingLeft="6dip"
    android:paddingRight="6dip" 
    />

</FrameLayout>

The adaptor is created in ListActivity.OnCreate, which calls setupViews():

  private void setupViews() {
    bOk       = (Button) findViewById(R.id.ButtonOK);
    bCancel   = (Button) findViewById(R.id.ButtonCancel);
    FListView = getListView(); 
    //
    bOk.setText("Select");
    //
    FListView.setItemsCanFocus(false);
    FListView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
    //
    bOk.setOnClickListener(this);
    bCancel.setOnClickListener(this);
    //
    ContentResolver content = getContentResolver();
    Cursor cursor = ApplicationHelper.MobilePhoneContacts(content);
    startManagingCursor(cursor);

    ListAdapter adapter = new CheckedCursorAdapter( SelectContacts.this, R.layout.row_contact, cursor,                
        new String[] {People.NAME, People.NUMBER},               
        new int[] {android.R.id.text1, R.id.tvNumber});          
    setListAdapter(adapter);
  }

The Custom adaptor:

  public class CheckedCursorAdapter extends SimpleCursorAdapter {

    Activity context;
    Cursor c;

    public CheckedCursorAdapter(Activity context, int rowContact, Cursor cursor, String[] strings, int[] is) {
      super(context, rowContact, cursor, strings, is);
      this.context = context;
      this.c = cursor;

    }

    public View getView(int position, View convertView, ViewGroup parent) {
      View row = convertView;
      ContactRowWrapper wrapper;

      if (row == null) {
        LayoutInflater inflater=context.getLayoutInflater();
        row = inflater.inflate(R.layout.row_contact, null);
        //
        wrapper = new ContactRowWrapper(row);
        row.setTag(wrapper);
      } else {
        wrapper = (ContactRowWrapper)row.getTag();
      }
      c.moveToPosition(position);
      wrapper.getTextView().setText( c.getString(c.getColumnIndex(Contacts.People.NUMBER)) );
      wrapper.getcheckBox().setText( c.getString(c.getColumnIndex(Contacts.People.NAME)) );
      wrapper.getcheckBox().setChecked(getListView().isItemChecked(position));
      //
      return row;
    }

  }

The crucial bit of code for for me was to get check boxes working was:

wrapper.getcheckBox().setChecked(getListView().isItemChecked(position));

Hope this helps you or anyone else who stumbles onto this question.

Also, pardon my Java noobness… I’ve only started Java a few weeks ago.
