Checkbox in listview with Custom SimpleCurser binding

Question

i think ive tried everything(made focusable:false!!) and i cant capture in anyway the selected checkbox on my list item. even OnItemClickListener, doesnt respond to any click.

how can i retrieve checked checkboxes in my list item? my list item inclused: image view, 4 textviews and the checkbox

some code:

this is in my ListActivity class:

final String columns[] = new String[] { MyUsers.User._ID, 
        MyUsers.User.MSG, MyUsers.User.LOCATION }; 

int[] to = new int[] { R.id.toptext, R.id.bottomtext,R.id.ChkBox, R.id.Location};

Uri myUri = Uri.parse("content://com.idan.datastorageprovider/users"); 

Cursor cursor = getContentResolver().query(myUri, columns, null, null, null);   

            startManagingCursor(cursor);   


ListCursorAdapter myCursorAdapter=new ListCursorAdapter(this, 
        R.layout.listitem, cursor, columns, to); 

 this.setListAdapter(myCursorAdapter); 

and this is my Custom Cursor adapter class:

public class ListCursorAdapter extends SimpleCursorAdapter
{

 private Context context; 
 private int layout; 

 public ListCursorAdapter(Context context, int layout, Cursor c, 
    String[] from, int[] to) 
{ 
   super(context, layout, c, from, to); 
   this.context = context; 
   this.layout = layout; 

} 

@Override 
public View newView(Context context, Cursor cursor, ViewGroup parent) 
{ 

   Cursor c = getCursor(); 

   final LayoutInflater inflater = LayoutInflater.from(context); 
   View v = inflater.inflate(layout, parent, false); 
           return v; 
} 

@Override
public void bindView(View v, Context context, Cursor c) 
{ 
    TextView topText = (TextView) v.findViewById(R.id.toptext); 
    if (topText != null) 
    { 
        topText.setText(""); 
    } 

    int nameCol = c.getColumnIndex(MyUsers.User.MSG); 
    String name = c.getString(nameCol); 
    TextView buttomTxt = (TextView) v.findViewById(R.id.bottomtext); 
    if (buttomTxt != null) 
    { 
        buttomTxt.setText("Message: "+name); 
    } 

nameCol = c.getColumnIndex(MyUsers.User.LOCATION); 
name = c.getString(nameCol); 
TextView location = (TextView) v.findViewById(R.id.Location); 
if (locationLinkTxt != null) 
{ 
    locationLinkTxt.setText(name); 
} 

I will appreciate any help! it's really depressing, I've tried many ways. many listeners, can't figure how to capture listener to my checkboxes.

The data I am binding to the list items from the database, isn't concered about the checkbox.. only the textviews.. there isn't any connection between the database and the checkbox I have in the list's item.

Thanks, idan.

Answer 1

I would recommend you use Android's built-in support for multiple-choice lists (CHOICE_MODE_MULTIPLE).

The List11.java SDK sample demonstrates this. You can also find a project from one of my tutorials that uses it here.

You can still use this technique with your own layout, so long as you include a CheckedTextView with android:id="@android:id/text1" as shown in the android.R.layout.simple_list_item_multiple_choice resource, a copy of which ships with your SDK.

check this example it is very good example for custom listview with checkbox.

Answer 3

I want also to select one item in the list (no CHOICE_MODE_MULTIPLE) and retrieve the states of the checkboxes. In my custom ListAdapter, I implemented something like :

    private void bindView(int position, View view) {
      final CheckBox myCheckBox = (CheckBox)view.findViewById(R.id.my_checkbox);

      final MyObject myModelObject = (MyObject)getItem(position);

      myCheckBox.setOnCheckedChangeListener(new OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
          myModelObject.setSelected(isChecked);
        }
    });

And in onItemClick() listener of the ListView, I can retrieve the checkboxes states with :

((MyObject)listView.getAdapter().getItem(n)).isSelected()
