如何在活动的特定片段中禁用抽屉选项 [英] How to disable drawer option in specific fragments of an activity

问题描述

我有一个包含5个片段的活动，我在活动中为抽屉使用了抽屉布局，但是我想仅在片段2中使用(启用)抽屉，并且我想在其余片段中禁用抽屉选项.

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.

有人可以帮我怎么做吗?

Can any one help me how to do this?

推荐答案

在您的activity中放入两种方法，一种禁用drawer，另一种再次启用它，如下所示:

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);
}

然后在您的fragments onCreateView(...)方法中放入:

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

fragmentInteractionListener.lockDrawer();

对于fragments，其中drawer应保持关闭状态，对于fragments，其中drawer应保持打开状态，

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

fragmentInteractionListener.unlockDrawer();
