Android - Navigation Drawer Button

I have integrated Navigation Drawer in my code. but it showing Back button instead 3 line drawer button. any one suggest me how can we add drawer button instead back button
Here is my code:
MainActvity.java
mNavigationDrawerFragment = (NavigationDrawerFragment)
getSupportFragmentManager().findFragmentById(R.id.navigation_drawer);
// drawer_content_padding is set to 0 on handsets and to 240 on tablets,
// so we can use it as a switch for locking the drawer
//mIsDrawerLocked = getResources().getDimensionPixelSize(R.dimen.drawer_content_padding) > 0;
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
// Set up the drawer.
mNavigationDrawerFragment.setUp(
R.id.navigation_drawer,
mDrawerLayout,
mIsDrawerLocked);
ActionBar actionBar = getSupportActionBar();
BitmapDrawable background = (BitmapDrawable)getResources().getDrawable(R.drawable.top_bg);
background.setTileModeX(Shader.TileMode.REPEAT);
actionBar.setBackgroundDrawable(background);
actionBar.setLogo(R.drawable.logo);
actionBar.setDisplayShowHomeEnabled(true);
actionBar.setDisplayUseLogoEnabled(true);
actionBar.setTitle("");

}
public static interface NavigationDrawerCallbacks {
/**
* Called when an item in the navigation drawer is selected.
*/
void onNavigationDrawerItemSelected(int position);
}

The main part is here:
NavigationDrawerFragment .java
...
if(locked) {
mIsDrawerLocked = true;
drawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_OPEN, mFragmentContainerView);
} else {
// set a custom shadow that overlays the main content when the drawer opens
mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
// set up the drawer's list view with items and click listener
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setHomeButtonEnabled(true);
}
I think locked value isfalse so by default actionBar.setDisplayHomeAsUpEnabled(true); is called and show the back button instead logo image.
Hope its helps!

How do I get my Navigation Drawer to work on all Activities?

You need to use a DrawerLayout, much in the same way you are doing it in activity_main.xml. I would actually recommend that you look into the Google I/O App. GitHub - iosched
There's an even simpler way to create Navigation Drawers now. Take a look into this Github project - Cheesesquare.

Change the Arrow Icon in the Drawer Menu?

I am using Android Studio. And I created a new activity with a navigation drawer.
But, It's showing the <- instead of the Hamburger Icon.
How can I modify my code to change <- to the Hamburger Icon????

use android.support.v7.app.ActionBarDrawerToggle instead of
android.support.v4.app.ActionBarDrawerToggle
you will get an error for the constructor of ActionBarDrawerToggle. Use the constructor for ActionBarDrawerToggle v7 with 4 parameters.
Also add this to your styles.xml
<style name="AppTheme" parent="Theme.AppCompat.Light">
<item name="drawerArrowStyle">#style/DrawerArrowStyle</item>
</style>
<style name="DrawerArrowStyle" parent="Widget.AppCompat.DrawerArrowToggle">
<item name="spinBars">true</item>
</style>
4.Apply this theme to your application in the manifest.
Hope this helps.

Add Following code in Your theme.
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="drawerArrowStyle">#style/DrawerArrowStyle</item>
</style>
<style name="DrawerArrowStyle" parent="Widget.AppCompat.DrawerArrowToggle">
<item name="spinBars">true</item>
<item name="color">#android:color/white</item>

The method addView(View, int) is undefined for the type NavigationDrawerFragment

I n my application I am using navigation drawer and action bar. I want to use these both almost in all activity of application. I had declared both in my MainActivity and other activity extends from this MainActivity. Now Action bar is visible. Drawer icon is also visible but on click of drawer icon drawer does not open. Here is my MainActivity

There is a
mUserLearnedDrawer = sp.getBoolean(PREF_USER_LEARNED_DRAWER, false);
change that code to the one of the followings
mUserLearnedDrawer = true;
or
mUserLearnedDrawer = sp.getBoolean(PREF_USER_LEARNED_DRAWER, true);
Or you can remove completely the logic of checking if the drawer is opened or not at the first time when the app runs and the related code to it (mUserLearnedDrawer variable and so on)
if (!mUserLearnedDrawer) {
// The user manually opened the drawer; store this flag to
// prevent auto-showing
// the navigation drawer automatically in the future.
mUserLearnedDrawer = true;
SharedPreferences sp = PreferenceManager
.getDefaultSharedPreferences(getActivity());
sp.edit().putBoolean(PREF_USER_LEARNED_DRAWER, true)
.commit();
