Question

I have the following code in my accounting application:

// switch View to the Customer layout, widget id's are the same on both layouts
private void hideExpenseView() {
    setContentView(R.layout.customer_invoices);
}

// switch View to the Supplier layout
private void hideIncomeView() {
    setContentView(R.layout.supplier_invoices);
}

The above does not work, as when you switch the ContentView, you lose all variable mappings. You have to map variables after you setContentView() unfortunately.

If this worked, this would be a beautifully simple solution for my app. See, I’ve named the widgets in both xml layouts the same ids. Instead of hiding elements of one xml layout based on different states, I switch the entire View to the appropriate layout – whether entering a Customer sales invoice, or a Supplier expense invoice.

By switching Views, I would have basically 6 lines of code taking care of the UI transition, very simple.

I hope this is still possible in another capacity, can someone please push me in the right direction?

Check out ViewSwitcher : see http://developer.android.com/reference/android/widget/ViewSwitcher.html

That, or base your activities layout in a framelayout that includes supplier_invoices.xml and customer_invoices.xml. Then your homegrown hide-n-show will be g2g. Tho, you might need to change the ids still.
