I am integrating Navigation drawer menu with Google Map fragement. I have a mapactivity it show the directions path from my start & destination value given in screen1. My mapactivity is showing the directions but while switching to another item in navigation menu my application doesn't shows up the next fragment.give me suggestions about map My MapActivity file as shown in below

Tabs should be placed along the top of an app, below the action bar - as stated in the android design guidelines.
Please spend some time looking at these guidelines for tabs here (and the rest of the guidelines), they're essential for developing android apps!

I am working on an app which has drawer layout with fragments.
There is a textview too which says signout in the drawer.
The issue is the signout works well initially. But when i switch to different activity and return back to previous activity then on opening the drawer, signout becomes unclickable as in the content below the drawer is getting clicked instead of signout.
The basic code for drawer layout is
public class MainActivity extends ActionBarActivity {
private DrawerLayout mDrawerLayout;
private LinearLayout drawer_linear;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
// nav drawer title
private CharSequence mDrawerTitle;
// used to store app title

#Override
public void onClick(View v) {
//Do Something
}
});
mTitle = mDrawerTitle = getTitle();
// load slide menu items
navMenuTitles = getResources().getStringArray(R.array.nav_drawer_items);
// nav drawer icons from resources
navMenuIcons = getResources()
.obtainTypedArray(R.array.nav_drawer_icons);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.list_slidermenu);

// adding nav drawer items to array
navDrawerItems.add(new NavDrawerItem(navMenuTitles[0], navMenuIcons.getResourceId(0, -1), true, String.valueOf(unreadCount)));

I'm new to android. My requirement is: I am having a home activity with a drawer layout (Navigation Drawer). I also have fragments with ViewPager.
My issues is, when I select other fragments, the slider works, but when I select the fragment with ViewPager(Fragment2 here in the code) the slider stops working.
My code is as below:
activity_home.xml

I am trying to apply an image header in my listview in the drawer layout.This is what i got so far.
However on clicking on Notifications,it opens School Fragment.Clicking on School opens Whats's hot fragment.
The problem is when inserting the image header which acts as part of the listview.
I need to apply it as a header.
This is the current code i am using:
Java:
View header=getLayoutInflater().inflate(R.layout.header, null);
ImageView pro=(ImageView)header.findViewById(R.id.profile_image);
pro.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), "Clicked", Toast.LENGTH_SHORT).show();
}
});
mDrawerList.addHeaderView(header);
XML:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"

All I needed to do was just add +1 in my position when clicking an item. This will add one more position which was taken by the header. Like this:
public void onItemClick(AdapterView parent, View view, int position, long id) {
// display view for selected nav drawer item
displayView(position+1);
}
I would suggest you to create a ListData.xml and set your the one item view of XML there such as image - text in a tablerow. Than set your ListAdapter to that ListData you've created. Then you should be having 0 issues with this.
You just set ItemClick and set the things you want to see as selected position.

XML for the drawer:

android:divider="#color/list_divider"

</android.support.v4.widget.DrawerLayout>
And Finally XML for the activity which I want to be called -
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView
android:id="#+id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:divider="#null" />
</LinearLayout>
The API for starting an Activity does not change when using a navigation drawer. You still only need to call startActivity() to launch a different Activity.
In this case, your code will look something like this:
private void displayView(int position) {
// update the main content by replacing fragments
Fragment fragment = null;
switch (position) {
case 0: // Or whatever nav item position should start the Activity
startActivity(new Intent(this, HomePage.class));
return;
// The rest of your cases
}
Note that when after calling startActivity() for the homepage item, we return instead of break so that your displayView() doesn't try to replace the displayed Fragment.
Im new to the ActionBarCompat library.I want to develop an app which contains multiple fragments. Here is what i want to do
1.How to open a fragment when user select that from Navigation Drawer.
2.How to set a startup fragment which displays startup layout (example- In Google plus app,first its displays news feeds.when we select profile item from the side menu,then its hide the side menu/Navigation drawer and displays the profile layout)
Currently i have side menu and one fragment.
Here is the tutorial that i used to follow- wptrafficanalyzer
If you are going to use a slide out menu I recommend you use this slidemenu library I use it in my applications and it allows you to place whatever you want in the slide out menu, the menu is just a frame layout and you can put whatever you want in it (Listview, GridView, or even just a picture)
I am assuming by side menu you meant Navigation Drawer. You can find an answer in the below link.
Navigation Drawer with backword compatibility android
Do read
http://developer.android.com/design/patterns/navigation-drawer.html
Fragment is hosted by a Activity. So you need a container in the activity layout.
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"

Initially you don't click any item. So initially add fragment1 to the container.
FragmentTransaction fragTran = getSupportFragmentManager()
.beginTransaction();
Fragment fragment1= new Fragment1();
fragTran.add(R.id.content_frame, fragment1);
fragTran.commit();
On click of listitem based on the position
FragmentTransaction fragTran = getSupportFragmentManager()
.beginTransaction();
Fragment fragment3= new Fragment3();
fragTran.replace(R.id.content_frame, fragment3);
fragTran.commit();
Hi check this code

android actionbarcompat is supported library for below android versions.In this you should do some modifications in code.I am giving some sample code with supported library
code:
