I am creating a flashlight app...I want to link two layouts in one java file...one layout is when the torch is unlit...and the other layout shows an illuminating torch...I have worked on it and now when i press the button it shifts to the other layout..(the illuminating one)...but does not come back to the first one when i click the button...What to do?Here is the code..My XML1:\[code\] <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:id="@+id/RelativeLayout1"android:layout_width="match_parent"android:layout_height="match_parent"android
