android:layout_toRightOf resource not found

Question

I have a strange issue after using Eclipse GUI to edit a layout. It is telling me that the resource tvVersionLabel cannot be found. Anything obvious?

        <TextView
            android:id="@+id/tvVersionLabel"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentLeft="true"
            android:layout_alignParentTop="true"
            android:gravity="center"
            android:text="Version: "
            android:textColor="@color/light_gray"
            android:textSize="13dip" />

        <TextView
            android:id="@+id/tvVersionNumber"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_toRightOf="@id/tvVersionLabel"
            android:gravity="center"
            android:text="default"
            android:textColor="#ffffff"
            android:textSize="13dip" />

Answer 1

Change this:

android:layout_toRightOf="@id/tvVersionLabel"

to this:

android:layout_toRightOf="@+id/tvVersionLabel"

The idea is the ids you have declared have different values and that's why the first view cannot be found if you declare it like that. More info (that you may be aware of), can be found here.

Answer 2

simply used @+id/ for android:layout_toRightOf
