This has been addressed in many posts on StackOverflow. The most recommended solution is to set:
android:descendantFocusability="blocksDescendants"
on the root layout of the list item layout. I've done the following.
android:descendantFocusability="blocksDescendants"
on the root
list item layout.setDescendantFocusability(BLOCK)
on the listView, as well as
each listViewItem.focus=disabled
on the ImageButtonsHowever when one of the child ImageButtons is clicked, I can't get any listeners on the ListView
or ListView
Items to fire.
Below is the "template" I am using to render a list item.
<LinearLayout

Am also setting this descendantFocusability in the code, just to be sure:
public class ReminderItemAdapter extends CursorAdapter {
. . .
@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
View v = mLayoutInflater.inflate(R.layout.reminder_item, parent, false);
parent.setDescendantFocusability(ViewGroup.FOCUS_BLOCK_DESCENDANTS);
((ViewGroup) v).setDescendantFocusability(ViewGroup.FOCUS_BLOCK_DESCENDANTS);
return v;
}
And on the styling of my ImageButton's I've set focusable=false, just for good measure:
<resources>
<style name="HorizontalButton">
<item name="android:layout_width">0dip</item>
<item name="android:layout_weight">1</item>
<item name="android:layout_height">match_parent</item>
<item name="android:fontFamily">sans-serif</item>
<item name="android:textSize">12sp</item>
<item name="android:background">?android:attr/selectableItemBackground</item>
<item name="android:focusable">false</item>
<item name="android:focusableInTouchMode">false</item>
</style>
. . .
I am getting onClick's received when clicking on any part of the list item, including the child TextView elements. However when clicking on any of the ImageButtons, the click's don't get picked up. (BTW I have got OnClickListeners registered with the ImageButtons and they are getting called.)
Have set:
But none of these get called if one of the ImageButtons is clicked.
Any help would be appreciated.
Try using this inside each button layouts
android:focusable="false"
android:focusableInTouchMode="false"
and remove other thing which you are doing for this. Also from listview. Also remove this
android:descendantFocusability="blocksDescendants"
and this too
parent.setDescendantFocusability(ViewGroup.FOCUS_BLOCK_DESCENDANTS);
((ViewGroup) v).setDescendantFocusability(ViewGroup.FOCUS_BLOCK_DESCENDANTS);
Just put
android:focusable="false"
in the row/item.xml of the listView .
It solve all your problem. if you put an event listener on the listView
.. It will not let you click on whole ListView Row. I mean
listView.setOnClickListener(this);
will not be called . because the focus moves to the row/item of the listView
. By adding android:focusable="false"
to the Button or ImageView on which you put an Event . It will lose their focus and the focus is gain by listView. Now you can have listView clickable as well as its descendents rows/item..
In short just put android:focusable="false
in TextView/Button or ImageView
which have event Listeners in the Item/row.xml.
Have you tried adding android:clickable="false" for the buttons? I just ran into a similar issue and that fixed it for me, whereas using android:focusable="false" did not.
Good luck!
