Question

In my main layout (mainlayout) I am displaying some text and images which are set dynamically based on the actions of the user. For one particular button click I need to display the contents of another layout (secondlayout). I do this using:

 setContentView(R.layout.secondlayout);

On the second layout I have another button that I use to return to the main layout, once again using:

 setContentView(R.layout.mainlayout);

The problem is on displaying the mainlayout again all the text and images I was displaying have now disappeared.

How can I return to the mainlayout and still display the contents I was displaying?

Answer 1

don’t do it that way. setContentView() is meant to be called once in your onCreate() method. however, couple of reasonable ways to do it,

1. encapsulate each layout in a fragment, then show / hide each fragment as needed.
2. bundle both layouts into a single layout, and show / hide each section of the layout by calling setVisibility() on the layout’s outermost container.
