androidandroid-listviewonitemlongclicklistener

ListView onItemClickListener works on part of custom row only

I have a custom ListView where each row consists of 3 items, a TextView (title), an ImageView (placeholder icon), and another TextView (content text). I have an OnItemLongClickListener set on the ListView and it is supposed to be that when a user clicks on the item in the ListView (which should be the entire row of 3 items all together as one), then a dialog comes up giving them the option to delete the whole item, which would then delete all 3 parts of that single list item.

But long clicking on the title view and the image do not trigger the listener. Only if the content TextView is long clicked, does the dialog box come up, which then deletes all 3, but clicking anywhere in the row should do that. However it doesn't. I need to find a solution because the user will not know to only click on the content TextView, they should be able to click anywhere.

I have looked on here to find a solution, and have tried adding these lines, but nothing has worked:

android:descendantFocusability="blocksDescendants" added to my ListView's LinearLayout.

android:clickable="false" to my ImageView.

android:focusable="false" and android:focusableInTouchMode="false" to both TextViews.

I don't have anything else to try. Any ideas?

UPDATE

When I added extra lines, like @Amrit suggested (code in his answer), the whole area when long clicked does now bring up the dialog box, but it creates this strange tint on the area I click, but only if I click the title TextView or the ImageView area. Oddly, that 2nd TextView still looks good and produces the dialog box as it should. Not sure how to get rid of this misaligned tint though:

Solution

  • Set all child views inside listView items to not focusable or clickable.

    android:focusable="false"
android:clickable="false"

    If it is not enough try setting 

    android:descendantFocusability="blocksDescendants

    to text_listview_row.xml linearlayout & 

    android:textIsSelectable="false"

    to textview's inside text_listview_row.xml

    UPDATE

    Actually all that I needed was that one line android:descendantFocusability="blocksDescendants" but inside of my LinearLayout parent of the text_listiew_row.xml (not needed in text_tab.xml). Thank you!
