DialogFragments with devices api level < 11

Question

I am in the process of making a honeycomb project/fork backwards compatible with 1.6+.

Based on the documentation provided by Google/Android I decided to build off all my fragments off DialogFragments which worked great for honeycomb...it gives me the flexibility to put anything as a dialog or 'full screen' element.

I've now incorporated the compatibility kit and moved my imports and method calls over to that. Now that I'm on 2.3 I am trying to launch an identical intent but I receive this issue:

java.lang.IllegalStateException: DialogFragment can not be attached to a container view

The documentation for DialogFragment suggests that it can perform as Fragment when you don't desire the dialog/popup functionality.

Answer 1

I managed to fix this properly in DialogFragment.java of the Compatibility Package:

Change line 74: boolean mShowsDialog = false;

Comment out line 232: //mShowsDialog = mContainerId == 0;

Then change the two show methods to this:

public void show(FragmentManager manager, String tag) {
    this.setShowsDialog(true);
    FragmentTransaction ft = manager.beginTransaction();
    ft.add(this, tag);
    ft.commit();
}

// JavaDoc removed
public int show(FragmentTransaction transaction, String tag) {
    this.setShowsDialog(true);
    transaction.add(this, tag);
    mRemoved = false;
    mBackStackId = transaction.commit();
    return mBackStackId;
}

Basically, they did write in support but the toggle to switch between dialog/embedded doesn't work.

So here we default to embedded, and then set to show as a dialog just before we show it.

You can use the android.support.v4.app.DialogFragment version, please check here

Answer 3

I've had the same problem. I never found a "correct" solution, but you can do the same thing by setting the theme of the Dialog in OnCreateDialog(). By setting the theme to android.R.style.Theme_Holo_DialogWhenLarge the dialog will be shown as a dialog on large and xlarge screens, while it'll be shown as a full screen window on small and normal screens.

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setStyle(STYLE_NO_TITLE, android.R.style.Theme_Holo_DialogWhenLarge);
}

I am using a DialogFragment child class and doing this trick in the onCreate() works. I call setShowsDialog() before onCreate() is called (in the onAttachFragment() of my Activity)

public class DialogFragmentHosted extends DialogFragment {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        boolean forceShowDialog = savedInstanceState==null;
        boolean showsDialog = getShowsDialog();
        super.onCreate(savedInstanceState);
        if (forceShowDialog )
            setShowsDialog(showsDialog);
    }
}
