Navigation Drawer And View Pager In Same Activity

I am trying to implement both navigation drawer and view pager in same activity. Navigation drawer works fine but the view pager is not working, also i am getting null pointer on

Solution 1:

The DrawerLayout should be the root element. Put the ViewPager inside it.

<android.support.v4.widget.DrawerLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.v4.view.ViewPager
        android:id="@+id/viewpager"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" />

    <ListView 
        android:id="@+id/left_drawer"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:background="#111"
        android:choiceMode="singleChoice"
        android:divider="@android:color/transparent"
        android:dividerHeight="0dp" />
</android.support.v4.widget.DrawerLayout>

Solution 2:

<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent" >

<android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent">

</android.support.v4.view.ViewPager>

<ListView
    android:id="@+id/left_drawer"
    android:layout_width="240dp"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:layout_below="@+id/top_bar"
    android:background="@android:color/darker_gray"
    android:choiceMode="singleChoice"
    android:divider="@android:color/background_dark"
    android:dividerHeight="1dp" />

</android.support.v4.widget.DrawerLayout>

Solution 3:

To achieve something like this:

Use simple one:

 <android.support.v4.widget.DrawerLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/drawer_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >    

       <android.support.v7.widget.Toolbar
             android:id="@+id/toolbar"
             android:layout_width="match_parent"
             android:layout_height="?attr/actionBarSize"
             android:background="?attr/colorPrimary"
             app:popupTheme="@style/AppTheme.PopupOverlay"/>

        <android.support.v4.view.ViewPager
             android:id="@+id/viewpager"
             android:layout_width="fill_parent"
             android:layout_height="fill_parent" >
        </android.support.v4.view.ViewPager>

        <ListView
            android:id="@+id/left_drawer"
            android:layout_width="240dp"
            android:layout_height="match_parent"
            android:layout_gravity="start"
            android:background="#111"
            android:choiceMode="singleChoice"
            android:divider="@android:color/transparent"
            android:dividerHeight="0dp" />
    </android.support.v4.widget.DrawerLayout>
