Can you please post some code, and clarify what you are trying to say? What is the textview you're referring to? What is the activity you're talking about? Please post more details. — Henry98, Aug 15 '15 at 03:43

Dude go through maps api on android.developer website. Through your second activity send the result back to the 1st one using intents.

Starting every sentence with "dude" is far from professional behavior. Beside that your answer is not a real answer as you mention only what the OP already tries. Voted down. – WarrenFaith Aug 21 '15 at 14:57
