I have an expandable list view, where the child view is a custom
layout consisting of 2 text views within a RelativeLayout as follows:
<RelativeLayout .....>
<TextView xmlns:android="http://schemas.android.com/apk/res/android";
android:id="@android:id/text1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingLeft="?android:attr/
expandableListPreferredItemPaddingLeft"
android:textAppearance="?android:attr/textAppearanceMedium"
android:gravity="center_vertical"
/>
<TextView xmlns:android="http://schemas.android.com/apk/res/android";
android:id="@+id/text2"
android:layout_height="fill_parent"
android:layout_width="wrap_content"
android:textAppearance="?android:attr/textAppearanceSmall"
android:layout_alignParentRight="true"
android:layout_centerInParent="true" android:numeric="integer"
android:text="@string/text2"/>
</RelativeLayout>
However, when I click on the child view the onChildClick() is not
getting called.
If I remove the second text view text2 above, then it works fine and
onChildClick() is called.
Can anyone help me identify the problem here?
This is the outline of my code:
ExpandableListView list = (ExpandableListView)
findViewById
(R.id.expandableListView);
list.setVisibility(View.VISIBLE);
Cursor groupCursor = managedQuery(Category.CONTENT_URI,
null, null, null, Items.DEFAULT_SORT_ORDER);
// Set up our adapter
mAdapter = new ShoppingListAdapter(groupCursor,
ShoppingListActivity.this,
R.layout.categories_list,//
android.R.layout.simple_expandable_list_item_1,
R.layout.items_list,//
android.R.layout.simple_expandable_list_item_1,
//android.R.layout.simple_list_item_multiple_choice,
new String[] {Category.NAME}, // Name for group
layouts
new int[] {android.R.id.text1},
new String[] {Items.NAME}, // Number for child
layouts
new int[] {android.R.id.text1});
list.setAdapter(mAdapter);
list.setOnChildClickListener(new OnChildClickListener(){
public boolean
onChildClick(ExpandableListView parent, View v,
int groupPosition, int childPosition, long id) {
// TODO Auto-generated method
stub
showEditQuantityDialog();
return true;
}
});
}
public class ShoppingListAdapter extends SimpleCursorTreeAdapter{
private String mItemsProjection[] = new String[] {
Items._ID, Items.NAME
};
private static final String ITEMS_SELECTION = Items.CATEGORY_ID +
"=?";
public ShoppingListAdapter(Cursor cursor, Context context, int
groupLayout,
int childLayout, String[] groupFrom, int[] groupTo,
String[]
childrenFrom,
int[] childrenTo) {
super(context, cursor, groupLayout, groupFrom, groupTo,
childLayout, childrenFrom,
childrenTo);
}
@Override
protected Cursor getChildrenCursor(Cursor groupCursor) {
// Given the group, we return a cursor for all the children
within that group
Long groupId = groupCursor.getLong
(groupCursor.getColumnIndexOrThrow(Category._ID));
String strGroupId = Long.toString(groupId);
String[] selectionArgs = new String[] { strGroupId };
// The returned Cursor MUST be managed by us, so we use
Activity's helper
// functionality to manage it for us.
return managedQuery(Items.CONTENT_URI, mItemsProjection,
ITEMS_SELECTION, selectionArgs, Items.DEFAULT_SORT_ORDER);
}
}
