Show/Hide Fragments and change the visibility attribute programmatically

Question

This is a 2 part problem. What I\'m having is a 3 Fragment layout where the 3\'rd Fragment(FragmentC) is added dynamically when the user taps a button found in another fragm

Answer 1

Create the Instances of fragments and add instead of replace

        FragA  fa= new FragA();
        FragB  fb= new FragB();
        FragC  fc= new FragB();
        fragmentManager = getSupportFragmentManager();
        fragmentTransaction = fragmentManager.beginTransaction();
        fragmentTransaction.add(R.id.fragmnt_container, fa);
        fragmentTransaction.add(R.id.fragmnt_container, fb);
        fragmentTransaction.add(R.id.fragmnt_container, fc);
        fragmentTransaction.show(fa);
        fragmentTransaction.hide(fb);
        fragmentTransaction.hide(fc);
        fragmentTransaction.commit();

suppose we want to to hide and show different fragments based on our action

    fragmentTransaction = fragmentManager.beginTransaction();
    fragmentTransaction.hide(fa);
    fragmentTransaction.show(fb);
    fragmentTransaction.hide(fc);
    fragmentTransaction.commit();
