ListView Delete Icon

Question

I am trying to fire a event when a user click the delete icon in the list , But I could not able to do it.I am using a simple cursor adapter with setviewbinder to display items in the list.In the setviewBinder method I set the textview layout clicklistener to be null that's why, view is not clicked when a user click in the textview.When a user is swipe in the list immediately delete icon is appeared.I need to fire a click event in the deleteIcon.Currently, when a user is clicked the delete icon, the whole view is clickable.I need to achieve when a user is clicked the delete icon, need to fired the event, only in the delete icon.

public boolean setViewValue(final View view, final Cursor data, int columnIndex) {
LinearLayout layoutTaskView=(LinearLayout)view.findViewById(R.id.layoutTaskView),
layoutTaskDelete = (LinearLayout) view.findViewById(R.id.LayoutDeleteTask);
boolean crossed = Boolean.valueOf(data.getString(columnIndex));
    if(crossed){
        icon.setImageState(new int[] { android.R.attr.state_checked }, true);
        text1.setPaintFlags(text1.getPaintFlags() | Paint.STRIKE_THRU_TEXT_FLAG);
        text2.setPaintFlags(text2.getPaintFlags() | Paint.STRIKE_THRU_TEXT_FLAG);
        layoutTaskView.setOnClickListener(null);
    }
    }

You need to use android:descendantFocusability = "afterDescendants" parameter to root layout of list item. In your case, the root LinearLayout.

For more information check this link.

EDIT : remove android:clickable="false" from your LinearLayout containing ImageView. Put android:clickable="true" in ImageView. Moreover, you can use ImageButton instead ImageView.

P.S. I have suggested to use android:descendantFocusability in main parent LinearLayout.
