I have to click on "A"symbol but at the same position some time "B"symbol is available . so when "B"symbol is available I don’t have to click . I try image exist and click activity but both symbol have same selector . so, it click for both. but I want it only click when “A” SYMBOL IS AVAILABLE.
What is a symbol? is it an image? it is kind of impossible for 2 different things to have the same selector, you can use uiexplorer to further inspect both to see what can be done to differentiate them.
