How To Close One Fragment When Isvisible

Hello i having an activity with fragment. I can just open one fragment when i click on icon or something like this But i want to close a fragment(or hide) with OnBackPressed method

Solution 1:

Override onBackPressed in your activity. If there is any fragment in backstack than popBackStack() otherwise simply finish() your activity.

private boolean allowedToExit = false; // class level

@Override
public void onBackPressed() {
    int backStackEntryCount = getSupportFragmentManager().getBackStackEntryCount();
    // this is the last item
    if (backStackEntryCount == 1) {
        if (allowedToExit)
            finish();
        else {
            allowedToExit = true;
            Toast.makeText(this, "Press again to exit", Toast.LENGTH_SHORT).show();
            new Handler().postDelayed(new Runnable() {
                @Override
                public void run() {
                    allowedToExit = false;
                }
            }, 1000);
            return;
        }
    }
    // we have more than 1 fragments in back stack
    if (backStackEntryCount > 1) {
        getSupportFragmentManager().popBackStackImmediate();
        // getSupportFragmentManager().beginTransaction().commit();
    } else
        super.onBackPressed();
}
