Question

我在NavigationView隐藏徽章时遇到困难。当我收到任何通知时添加了BottomNavigationNiew位置的徽章，但在点击该位置时无法刷新该批次。

摇篮：

compile 'com.github.ittianyu:BottomNavigationViewEx:1.1.7'
compile 'q.rorbin:badgeview:1.1.0'

MainActivity：

private Badge addBadgeAt(int position, int number) {
        return new QBadgeView(this)
                .setBadgeNumber(number)
                .setGravityOffset(42, 2, true)
                .bindTarget(bottomNavigationView.getBottomNavigationItemView(position)); 
}


@Override
public boolean onNavigationItemSelected(@NonNull MenuItem item) {

    FragmentManager fragmentManager;
    FragmentTransaction fragmentTransaction;

    switch (item.getItemId()) {
        case R.id.menu_conection:

            fragmentManager = getSupportFragmentManager();
            fragmentTransaction = fragmentManager.beginTransaction();
            fragmentTransaction.replace(R.id.container, ConnectionFragment.newInstance("connection"));
            fragmentTransaction.commit();

            break;
        case R.id.menu_me:
            fragmentManager = getSupportFragmentManager();
            fragmentTransaction = fragmentManager.beginTransaction();
            fragmentTransaction.replace(R.id.container, MyProfile.newInstance(ARG_TYPE));
            fragmentTransaction.commit();

            break;

        case R.id.menu_notification:

            fragmentManager = getSupportFragmentManager();
            fragmentTransaction = fragmentManager.beginTransaction();
            fragmentTransaction.replace(R.id.container, NotificationsFragment.newInstance());
            fragmentTransaction.commit();

            break;
    }

    return true;
}

我只想在点击menu_notification

时删除第二个位置的徽章

Answer 1

public static void removeBadge(int position, BottomNavigationViewEx bottomNavigationViewEx, QBadgeView badgeView) {
badgeView.bindTarget(bottomNavigationViewEx.getBottomNavigationItemView(position))
                .hide(true);
    }

Answer 2

调用addBadgeAt函数时，需要将返回的Badge对象赋值给变量：

mBadge = addBadgeAt(2, 1);

然后，当您想删除徽章时，只需拨打hide方法：

即可

mBadge.hide(true);

注意：似乎调用两次隐藏方法会导致徽章再次显示。
