Everything works fine only my main image which is coming from database is going slightly upwards, whereas the example which I copied in that the image is looking perfectly.
I don't know why my image is going upwards. The image should render like this :

I tried doing debugging but then also no use, it's so weird problem.

The problem occur for main_content xml . your image is cut off when you use it in you main_activity xml . Use this trick it will work . Simple put margin above your main_content xml
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:layout_marginTop="?actionBarSize"

android:layout_width="match_parent"
android:layout_height="match_parent">
</FrameLayout>

You have to include a custom action bar in your layout.
Please follow this link. It is explained very nicely with the code snaps and in depth. :)

In MainAcitivity you should extends Activity no an AppCompatActivity. AppCompatActivity show a bar

In onNavigationItemSelected method do not create the DrawerLayout again. Simply call the closeDrawer.
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); --> remove this line of code
drawer.closeDrawer(GravityCompat.START);
UPDATE
In your onCreate method change this line of code
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
to
drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
and add this line of code
DrawerLayout drawer
below this line of code
ViewPager mViewPager;
and remove the indicated line of code in onNavigationItemSelected method

if (id == R.id.home) {
fragmentManager.beginTransaction().replace(R.id.content_frame,new HomeFragment()).commit();
} else if (id == R.id.announcement) {
fragmentManager.beginTransaction().replace(R.id.content_frame,new AnnouncementFragment()).commit();
update above code as below :
if (id == R.id.home) {
fragmentManager.beginTransaction().replace(R.id.content_frame,new HomeFragment()).addToBackStack(null).commit();
} else if (id == R.id.announcement) {
fragmentManager.beginTransaction().replace(R.id.content_frame,new AnnouncementFragment()).addToBackStack(null).commit();

in this class i am extending it:
public class Contact extends NavigationActivity implements View.OnClickListener {
private EditText mName,mNumber,mEmail,mMessage;
private FancyButton mSbmt;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_contact);

So, first of all you have to create a base abstract Activity with DrawerLayout:
public abstract class NavigationActivity extends AppCompatActivity {
private DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle mDrawerToggle;
#Override
protected void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (getSupportActionBar() != null) {
getSupportActionBar().setDisplayShowHomeEnabled(true);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowTitleEnabled(true);
getSupportActionBar().setTitle("Title");
}
}
/**
* This method overrides the setContentView method to set DrawerLayout as a main layout.
*
* #param layoutResID Layout, which will be set in DrawerLayout as a content frame
*/
#Override
public void setContentView(final int layoutResID) {
super.setContentView(R.layout.navigation_drawer);
final ViewStub content = (ViewStub) findViewById(R.id.content_frame);
content.setLayoutResource(layoutResID);
content.inflate();
initDrawer();
}
/**
* This method initializes DrawerLayout and DrawerToggle
*/
private void initDrawer() {
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
mDrawerToggle = new ActionBarDrawerToggle(
this,
mDrawerLayout,
null,
R.string.drawer_open,
R.string.drawer_close
) {
public void onDrawerClosed(final View view) {
//invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
public void onDrawerOpened(final View drawerView) {
//invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
}
#Override
protected void onPostCreate(final Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
// Sync the toggle state after onRestoreInstanceState has occurred.
mDrawerToggle.syncState();
}
#Override
public void onConfigurationChanged(final Configuration newConfig) {
super.onConfigurationChanged(newConfig);
// Pass any configuration change to the drawer toggls
mDrawerToggle.onConfigurationChanged(newConfig);
}
#Override
public boolean onOptionsItemSelected(final MenuItem item) {
return mDrawerToggle.onOptionsItemSelected(item) || super.onOptionsItemSelected(item);
}
/**
* This method is called when user presses the back button. If the drawer is opened, it will be closed.
* Otherwise will be called the parent implementation.
*/
#Override
public void onBackPressed() {
if (mDrawerLayout.isDrawerOpen(GravityCompat.START)) {
mDrawerLayout.closeDrawers();
} else {
super.onBackPressed();
}
}
}
Which uses a layout navigation_drawer.xml:
<?xml version="1.0" encoding="utf-8"?>
<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">
<ViewStub
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<RelativeLayout
android:id="#+id/drawer_container"
android:layout_width="#dimen/drawer_width"
android:layout_height="match_parent"
android:orientation="vertical"
android:clickable="true"
android:background="#color/gray_dark"
android:layout_gravity="start">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="This is drawer"/>
</RelativeLayout>
</android.support.v4.widget.DrawerLayout>
After that you can simply create some Activity and set its layout into ViewStub with id "content_frame". It will be done automatically in setContentView method in NavigationActivity
public class MainActivity extends NavigationActivity {
#Override
protected void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
You also have to use a theme with ActionBar:
<resources
xmlns:tools="http://schemas.android.com/tools"
xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light">
<item name="actionBarStyle">#style/MyActionBar</item>
</style>
<style name="MyActionBar" parent="#style/Widget.AppCompat.Light.ActionBar.Solid">
<item name="background">#android:color/white</item>
<item name="android:background" tools:ignore="NewApi">#android:color/white</item>
</style>
</resources>
And set it in your manifest file:
<application
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme">
...

If you want to add navigation drawer to your other activities you can do that by extending DrawerActivity in your TabActivity.
For further reference check this link.
https://stackoverflow.com/a/21406760/4646227

in your drower layout you should add tab layout like this :
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"

android:id="#+id/drawer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:layout_gravity="end"
tools:context=".MainActivity">
<android.support.design.widget.CoordinatorLayout
android:id="#+id/root_view"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/ColorPrimary"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<include

The Volunteer Fragment is not a Fragment as it extends AppCompatActivity. It should extend Fragment.
In the navigation drawer click listener you then should do something like this:
getSupportFragmentManager().beginTransaction().replace(R.id.frame_container, new Fragment_Volunteer()).commit();

you should use only Activity: "MainActivity"
and when you show "Fragment_Volunteer" on item menu put inside switch case:
getSupportFragmentManager()
.beginTransaction()
.replace(R.id.frame_container, new Fragment_Volunteer())
.commit();
use the code next:
Fragment_Volunteer extends Fragment
finally Fragment not use:
protected void onCreate(Bundle savedInstanceState) {}
the code correct is this:
public class Fragment_Volunteer extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.activity_profile, container, false);
return view;
}
}
I hope to help, sorry for my bad english
