android - Multiple choice list with custom view?

Question

I've seen example com.example.android.apis.view.List11 from ApiDemos. In that example, each row takes the view android.R.simple_list_item_multiple_choice. Each such view has a TextView and a CheckBox.

Now I want each view to have 2 TextViews and 1 CheckBox, somewhat similar to the List3 example. I tried creating a custom layout file row.xml like this:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
    <CheckBox
        android:id="@+id/checkbox"
        android:layout_alignParentRight="true"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent" />
    <TextView
        android:id="@+id/text_name"
        android:textSize="13px"
        android:textStyle="bold"
        android:layout_toLeftOf="@id/checkbox"
        android:layout_alignParentLeft="true"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" />
    <TextView
        android:id="@+id/text_phone"
        android:textSize="9px"
        android:layout_toLeftOf="@id/checkbox"
        android:layout_below="@id/text_name"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" /> 
</RelativeLayout>

Then in Activity's onCreate(), I do like this:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // Query the contacts
    mCursor = getContentResolver().query(Phones.CONTENT_URI, null, null, null, null);
    startManagingCursor(mCursor);

    ListAdapter adapter = new SimpleCursorAdapter(this,
            R.layout.row,
            mCursor, 
            new String[] { Phones.NAME, Phones.NUMBER}, 
            new int[] { R.id.text_name, R.id.text_phone });
    setListAdapter(adapter);
    getListView().setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
}

The result kind of looks like what I want, but it looks like the list doesn't know which item of it is selected. Also, I need to click exactly on the CheckBox. In the List11 example, I only need to click on the item row.

So what do I need to do to make a multiple choice list with my custom view for each row? Many thanks.

Answer 1

You have to make your own RelativeLayout that implements the Checkable interface and have a reference to the CheckBox or to the CheckedTextView (or a list if it's multiple choice mode).
