(can't find id reference) No resource matches the given name at

Question

I have the following inside a relative layout.

Answer 1

The layout which you are trying to use as a reference should be defined before it is used as reference i.e. use as 'layout_toLeftOf'.

It is like you have to declare a variable in java before using it. Declare then use it ...

If you need to mention the id before its defined in the file, then you need to use @+id/textView1 instead of @id/textView1
