Question

我有一个Activity，每边有两个NavigationDrawer个。我想清理它并将两个菜单拉出到自己的xml文件中，并使用include在主xml中引用它们。这适用于左侧抽屉，但不适用于右侧。

<include
    android:id="@+id/friendsInclude"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    layout="@layout/friend_feed" 
    android:layout_gravity="start"/>

<!-- Notification Feed -->

<include
    android:id="@+id/notificationInclude"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    layout="@layout/notification_feed"
    android:layout_gravity="end" />

两者都有自己的XML，根布局是相对布局。它们看起来像这样......

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:bootstrapbutton="http://schemas.android.com/apk/res-auto"
    xmlns:fontawesometext="http://schemas.android.com/apk/res-auto"
    xmlns:bootstrapthumbnail="http://schemas.android.com/apk/res-auto"
    android:id="@+id/friendsLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_gravity="start" 
    android:background="#F5F5F5">

和

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:bootstrapbutton="http://schemas.android.com/apk/res-auto"
    xmlns:fontawesometext="http://schemas.android.com/apk/res-auto"
    xmlns:bootstrapthumbnail="http://schemas.android.com/apk/res-auto"
    android:id="@+id/notificationsLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_gravity="end"
    android:background="#F5F5F5" >

在我们的主要活动中，我们在尝试通过操作栏打开右侧抽屉时获得空指针。

@Override
public boolean onOptionsItemSelected(MenuItem item) {

    // Pass the event to ActionBarDrawerToggle, if it returns
    // true, then it has handled the app icon touch event
    if (mDrawerToggle.onOptionsItemSelected(item)) {
        return true;
    }

    if(item.getItemId() == R.id.notifications) {

        if(drawerLayout.isDrawerVisible(notificationsLayout)) { //nullpointer
            drawerLayout.closeDrawer(notificationsLayout);
        } else {
            drawerLayout.openDrawer(notificationsLayout);
            drawerLayout.closeDrawer(friendsLayout);
        }
    }

    if(item.getItemId() == R.id.refresh) {
        new AsyncMainFeed(this).execute("");
        new AsyncFriendFeed().execute("");
        new AsyncNotificationFeed(this).execute("");
    }
    // Handle your other action bar items...

    return super.onOptionsItemSelected(item);
}

我宣布我的布局是这样的

    friendsLayout = (RelativeLayout)findViewById(R.id.friendsLayout);
    notificationsLayout = (RelativeLayout)findViewById(R.id.notificationsLayout);

我有点难过这是来自任何想法的地方？

使用包含两个导航抽屉
