CheckBox doesn't change state

1.9k views Asked by At

I have a:

public class MyList extends ListActivity {
    SimpleAdapter simpleAdapter;

Binding to the ListView is done by a ViewBinder:

    simpleAdapter = new SimpleAdapter(this, getData(path),
            R.layout.menu_row, new String[] { 
        ..., "checked" }, new int[] {..., R.id.checkBox1 });

    SimpleAdapter.ViewBinder viewBinder = new SimpleAdapter.ViewBinder() {
        @Override
        public boolean setViewValue(View view, Object data,
                String textRepresentation) {
            if (view.getId() == R.id.checkBox1) {
                                CheckBox checkBox = (CheckBox) view;
                checkBox.setChecked(Boolean.parseBoolean((String) data));

My xml looks like this, clickable and focusable helps that the row behaves seen as one.

<CheckBox
    android:id="@+id/checkBox1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:focusable="false"
    android:clickable="false"
    android:focusableInTouchMode="false"
     />

I also have a:

protected void onListItemClick(ListView l, View v, int position, long id) {

which interacts with the click event. This works good so far, my problem is when I click on a row, the CheckBox doesn't change its visual state. What can I do?

Put a button.setChecked(true) in you're onListItemClick ( or code to toggle back and forth using setChecked).

EDIT

Misunderstood your issue. Have you told the adapter that the dataset has been changed?

I think what you want to look into is a CheckedTextView which shows a check box and when a list item is clicked the check box changes
