No resource found that matches the given name for Layout_to_left_of

Question

why the layout_toLeftOf attribute could not find the resource. I did have that id in the layout, and why this happens. I am using Intellij IDEA, even I tried to rebuild the code, the error still exists. Any advice, thanks in advance.

Answer 1

The reason is that list_item_action is defined after it is used. It is defined in the last. It is used before.

As suggested by amit singh - use: @+id => This will define if it is not defined already. Alternatively, move the definition of list_item_action before you use it.

Answer 2

Replace this line-

android:layout_toLeftOf="@id/list_item_action"

with this line-

android:layout_toLeftOf="@+id/list_item_action"
