Question

I am working on fragment concepts in andorid.I am adding multiple layouts into one FrameLayout,

FragmentManager fm = getFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
ft.addToBackStack("web");
ft.setTransitionStyle(FragmentTransaction.TRANSIT_ENTER_MASK);
Fragment fragment = new TestFragment();
ft.setCustomAnimations(R.anim.right_to_left_remove, R.anim.right_to_left_add);
ft.add(R.id.test, fragment);
ft.commit();

I clicked the button in fragment1, fragment2 added above with fragment1, when click the same area of fragement2 layouts with no buttons another one fragment added. Fragment1 button clickable in Fragment2, so the fragments multiple time adding.

How do I disable click events in fragment2 layouts??

Thanks,

Try to use ft.replace instead of ft.add

If you want to use ft.add , at lest remove the old fragment:

FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.add(R.id.main, new Fragment1(), "frag1");
ft.add(R.id.main, new Fragment2(), "frag2");
ft.commit();

// Later on
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
// Manually remove fragments
ft.remove(getSupportFragmentManager().findFragmentByTag("frag1"));
ft.remove(getSupportFragmentManager().findFragmentByTag("frag2"));
ft.add(R.id.main, new Fragment1(), "newFrag1");
ft.commit();
