在运行时为对话框选择布局

Question

I need to extend DialogFragment to create dialogs that take user input and store them to be manipulated by another class. There are around six different layouts that could need to be displayed depending on which option the user selects. Extending dialogfragment six times doesnt sit well with me as a devoted initiate into OOP. My question then is how could I pass a layout to the DialogFragment at runtime.

I have tried both creating a class variable and a getter method in AdvantageDialog both to no avail.

It's instantiated like this

    DialogFragment newFragment = new AdvantageDialog();
    newFragment.show(getFragmentManager(), "add_advantage");

but then newFragment.inputScreen nor newFragment.setInputScreen(some int) can be accessed from outside (ie. "setInputScreen(int) is undefined for the type dialogfragment").
I guess it would work if I did AdvantageDialog aD = new AdvantageDialog and then aD.setInputScreen(some int) but then I wouldnt benefit from the DialogFragment handling lifecycle methods. Also as far as I can see also there are no methods in the API for setting the view, only possible to change the view container.

Please any idea how to do this or can you direct me to where exactly my understanding is lacking. It would be greatly appreciated. Andy

Fragment has the setArgument and getArgument method. You can provide the layout id through the bundle that seArgument takes as parameter and getArgument returns, and use this id inside onCreateView to inflate the corresponding view's object
