How to disable drawer option in specific fragments

问题:

I have an activity with 5 fragments, I used drawer layout in my activity for a drawer, but I want to use(enable) the drawer in only fragment 2 and I want to disable the drawer option in remaining fragments.

Can any one help me how to do this?

Put two methods in the your activity, one to disable the drawer and one to enable it again, like so:

public void lockDrawer() {
    drawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);
}


public void unlockDrawer() {
    drawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED);
}

Then in your fragments onCreateView(...) method put:

fragmentInteractionListener.lockDrawer();

for the fragments where the drawer should stay shut and for the fragments where the drawer should stay open put:

fragmentInteractionListener.unlockDrawer();

P.S: for tutorials in how to correctly implement a fragment interaction listener see:
