first you have to put your whole view inside a drawerlayout like this
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
android:id="#+id/drawer_layout"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center_horizontal"
android:gravity="center_horizontal"
android:orientation="vertical">
<include
layout="#layout/activity_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:menu="#menu/activity_main_drawer"/>
</android.support.v4.widget.DrawerLayout>
here activity layout is the main layout with all the views

activity_main.xml should be like this:
<android.support.v4.widget.DrawerLayout
android:id="#+id/drawerLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<FrameLayout
android:id="#+id/container_frame"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"/>
<ListView
android:id="#+id/list_slidermenu"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="#color/list_divider"
android:dividerHeight="1dp"
android:listSelector="#drawable/list_selector"
android:background="#color/list_background"/>
<ListView
android:id="#+id/list"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:divider="#color/list_divider"
android:dividerHeight="1dp"
android:listSelector="#drawable/list_row_selector"
android:background="#color/list_background"/>

add these lines in your onCreate() method
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);

Drawer Layout only takes 2 children.. one is main content and other is the drawer
In your case you just need to modify your layout file like below:
<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">
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="64dp"
android:layout_gravity="left"
android:background="#ffffff"
android:minHeight="?attr/actionBarSize" />
<!-- The main content view -->
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<!-- Add content here -->
</FrameLayout>
</LinearLayout>
<!-- The navigation drawer -->
<ListView android:id="#+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
android:background="#ffffff"/>
</android.support.v4.widget.DrawerLayout>
Your Drawerlayout has to be parent layout and rest 2 childs i.e. linearlayout and listview

fragment transparent and overlay another fragment navigation drawer android

I'm using a navigation drawer in my application with android.support.v4.app.Fragment. The problem is that my navigation menu is always transparent and sometimes when I change the fragment I can see the previous one behind the new one "overlaying" (I said sometimes not always).
This is my main code:
public class Main extends FragmentActivity {
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
private ImageLoader mLoader;
static String destinationFile;
private CharSequence mDrawerTitle;
private CharSequence mTitle;

and for the section i have the below xml :
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"

<TextView
android:id="#+id/navmenusection_label"
style="?android:attr/listSeparatorTextViewStyle"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#BBB"
android:paddingBottom="7dp"
android:paddingTop="7dp"
android:text="Section"
android:textColor="#FFFFFF"
android:textSize="18sp" />
</RelativeLayout>
So how can i add the section in the navigation drawer. ?
i have change the NavDrawerListAdapter.java file :
public class NavDrawerListAdapter extends BaseAdapter {
private Context context;
private ArrayList<NavDrawerItem> navDrawerItems;
public NavDrawerListAdapter(Context context,
ArrayList<NavDrawerItem> navDrawerItems) {
this.context = context;
this.navDrawerItems = navDrawerItems;
}
#Override
public int getCount() {
return navDrawerItems.size();
}
#Override
public Object getItem(int position) {
return navDrawerItems.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
LayoutInflater mInflater = (LayoutInflater) context
.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
convertView = mInflater.inflate(R.layout.drawer_list_item, null);
/*
* convertView = mInflater.inflate(R.layout.navdrawer_section,
* parent, false);
*/
}
ImageView imgIcon = (ImageView) convertView.findViewById(R.id.icon);
TextView txtTitle = (TextView) convertView.findViewById(R.id.title);
TextView txtCount = (TextView) convertView.findViewById(R.id.counter);
imgIcon.setImageResource(navDrawerItems.get(position).getIcon());
txtTitle.setText(navDrawerItems.get(position).getTitle());
// displaying count
// check whether it set visible or not
if (navDrawerItems.get(position).getCounterVisibility()) {
txtCount.setText(navDrawerItems.get(position).getCount());
} else {
// hide the counter view
txtCount.setVisibility(View.GONE);
}
return convertView;
}
}
convertView = mInflater.inflate(R.layout.navdrawer_section,
parent, false);
i have put this in getView() but i am getting the error .

how can i add the section ?

first remove any changes that you have done which causes a null pointer exception then go to drwer_list_item.xml and add text view for your section part, then go to NavDrawerItem.class and add:
private String section;
change your constructor to this:
public NavDrawerItem(String title, int icon,String section){
this.title = title;
this.icon = icon;
this.section= section;
}
you also have to add getters and setters for your private section instanse:
public String getSection(){
return this.section;
}
public void setSection(String section){
this.section = section;
}
then go to navDrewerListAdapter.class and add this:
TextView txtSection = (TextView) convertView.findViewById(R.id.section);
last thing you have to do is to change your navDrawerItems.add from this:
navDrawerItems.add(new NavDrawerItem(navMenuTitles[index], navMenuIcons
.getResourceId(index, -1)));
to this:
navDrawerItems.add(new NavDrawerItem(navMenuTitles[index], navMenuIcons
.getResourceId(index, -1),"String Section"));
hope this will help.

Android: 2 Listviews in NavigationDrawer

I've done a Navigation Drawer in my app and the works ok. But I'm trying to put another Listview below the above but I can not get the new display on the screen. I have put the Navigation Drawer in BaseActivity class. What can be the error? This is my code:
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" >
<LinearLayout
...
</LinearLayout>
<LinearLayout android:layout_width="250dp"
android:layout_height="match_parent"

Have you tried adding layout weight to your ListViews? A ListView will naturally match it's parent's size.
Layout Weight I hope it helps.
