I have a ListView with an ArrayList adapter. The rows are not very complex (an Image on the left, a LinearLayout with TextViews inside, and a CheckBox on the right ... the layout is copied in below.) The goal is to have a QuickAction bar come up if the user clicks on the image or text, and have the CheckBox change state if the user clicks on the CheckBox. I have each part working independently, but not when they're together in the layout - somehow, I'm losing the onItemClick event.
The "QuickAction" bar is activated by OnItemClickListener(), and it works fine - unless I have the CheckBox in the layout, in which case the CheckBox works fine (using onClick()) but the onItemClickListener is never fired if the user clicks in the row but outside the CheckBox. The layout (minus some style stuff) is:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/vw1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<ImageView android:id="@+id/img"
android:layout_alignParentLeft="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<CheckBox android:id="@+id/ckb"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_gravity="right"
android:checked="false" />
<!-- stack text in middle section of the row -->
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
>
<TextView android:id="@+id/text1"
android:layout_width="wrap_content"
android:layout_height="wrap_content""/>
<TextView android:id="@+id/text2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
</RelativeLayout>
The code behind it isn't complicated:
public class ListGroupsActivity extends BaseActivityForList {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_list);
// add QuickAction bar
ListView lv = getListView();
lv.setOnItemClickListener(new QAListener(this));
}
}
//inner classes of the ListGroupsActivity
class CbOnClickListener implements OnClickListener {
// ...
// test the checkbox isChecked() and keep state in 'selectedItems' array
class GroupListAdapter extends ArrayAdapter<Group> {
super(/*...*/)
CbOnClickListener cblistener = null; // common listener for all the CheckBoxes
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// here do normal testing for convertView being null etc
// heres the view inflation from the layout into the ViewHolder
holder.tv1 = (TextView) convertView.findViewById(R.id.text1);
holder.tv2 = (TextView) convertView.findViewById(R.id.text2);
holder.img = (ImageView) convertView.findViewById(R.id.img);
holder.ckb = (CheckBox) convertView.findViewById(R.id.ckb);
Group g = groups.get(position); // this is the data obj for the row
holder.tv1.setText(g.getName());
holder.tv2.setText("child groups");
Bitmap bm = BitmapFactory.decodeFile(g.getIconUri());
holder.img.setImageBitmap(bm);
Integer key = (Integer) g.getId();
holder.ckb.setChecked(selectedItems.contains(key));
holder.ckb.setOnClickListener(cblistener); // hook onClick to cblistener
return convertView;
}
The QAListener is in a superclass for all my list activities:
public class BaseActivityForList extends
OrmLiteBaseListActivity<DatabaseHelper> {
// QAListener inner class, constructs new quick action bar when item clicked
class QAListener implements OnItemClickListener {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// has three ActionItem instances, 'copyAction', 'delAction', 'editAction'
ActionItem copyAction = new ActionItem();
copyAction.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// ... does some stuff
mQuickAction.dismiss();
}
}); // end setOnClickListener
} // end onItemClick
} // end QAListener
} end BaseActivityForList
So, how do I arrange for the Checkbox to pick up the onClick, and the rest of the list item to pick up the onItemClick()?
