Question

I have problem in replacing fragments in android.

Both of my fragment layouts are placed in a FrameLayout.

And I have tried replacing two fragment using this code :

  Fragment newFragment = new StatisticsFragment();
        FragmentTransaction transaction = getFragmentManager().beginTransaction();

        transaction.replace(((ViewGroup)(getView().getParent())).getId(), newFragment);
        transaction.addToBackStack(null);

        // Commit the transaction
        transaction.commit();

The problem is that after replacing the Fragment, its layout is not shown although its OncreateView is called.

Please help me.

EDIT : I put the hole code.

I solved my problem by adding background color to my layouts.

Answer 1

This is how I replace frameLayouts with fragments:

 fm = getSupportFragmentManager();
 Fragment_Main main = new Fragment_Main();

 fm.beginTransaction().replace(R.id.mainContainer, main).commit();

Try adding .commit before ending the statement

This method allows you to load any Fragment to any FrameLayout:

/**
 * Function to load a fragment into a inner FrameLayout of auction precap view
 * @param Fragment to load
 * @param If of the container to load fragments to
 */
private void loadInnerFragment(Fragment fragment, int containerId) {
    try {
        FragmentManager childFragmentManager = getChildFragmentManager();
        FragmentTransaction transaction2 = childFragmentManager.beginTransaction();
        transaction2.replace(containerId, fragment);
        transaction2.commit();
    }
    catch (Exception e) {
        e.printStackTrace();
    }
}

Thus, just do:

Fragment newFragment = new StatisticsFragment();
        loadInnerFragment(
                newFragment,
                R.id.container
        );

Where R.id.container is the ID of your FrameLayout

The replaced Fragment layout is not shown
