Android: Navigation Drawer with Multiple activities.

Now a days most of the Android application are using Navigation Drawer/Sliding Drawer like view.
Some of them are using library for doing this. Android has also provided Navigation Drawer to achieve this.
http://developer.android.com/training/implementing-navigation/nav-drawer.html

In this above link we can find demo app to add navigation drawer in our app. But we have to use fragment for achieving this and it is recommend to use fragment.

But in case if we don't want to use fragment or we want to add Navigation Drawer in already existing app which contain activities and we don't want to replace them with fragment.

We can achieve same Navigation Drawer with activities too....I am going to add here demo app to add Navigation Drawer with multiple activities.


First of all we have to create on BaseActivity which will contain layout and all the code related to navigation drawer and then we will use this BaseActivity as parent activity to other activities.

We will extends this BaseActivity  to all the other activities rather than directly extending Activity class in our activities. This way our all the activities will contain same Navigation Drawer without adding any extra code in every activity.

About Code:::

First of all we have to create XML file for adding navigation drawer, we will use this layout xml file in our BaseActivity.

navigation_drawer_base_layout.xml

<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" >

    <FrameLayout
        android:id="@+id/content_frame"
        android:layout_width="match_parent"
        android:layout_height="match_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>

As we are already adding layout in BaseActivity we can not add layout in child activity..otherwise it will not work properly so we will add our own layout for the child activity in FrameLayout of above XML.

/* Layout Inflater to add view in frame layout*/
Code Example :: getLayoutInflater().inflate(R.layout.activity_main, frameLayout);
This way we will get our own layout in child activity. Now we can use this as any other normal activity.

------------------------------------------------------------------------------------------------------------
Attaching another demo example here as lots of visitors are getting confused how to add different layout on different activity and how to add icon on navigation list view. 
As well as added header on listview to make it little bit attractive.
