I Found this tutorial realy clear and helpful for creating a Fragment ViewPager:

Check it out, in addiotion please refer to here as well:

ViewPager without tabs:

UPDATE:

First of all remove this part:

<activity android:name="slider.example.Fragment0" android:theme="@android:style/Theme.NoTitleBar" android:screenOrientation="portrait" />
<activity android:name="slider.example.Fragment1" android:theme="@android:style/Theme.NoTitleBar" android:screenOrientation="portrait" />
<activity android:name="slider.example.Fragment2" android:theme="@android:style/Theme.NoTitleBar" android:screenOrientation="portrait" />
<activity android:name=".MyPagerAdapter"></activity>

Not the Fragments or the Adapter are not activities and you shouldn't write them into the manifest file.

and try to change this part:

<activity android:name="slider.example.ViewPagerFragmentActivity"
              android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

To this:

<activity android:name=".ViewPagerFragmentActivity"
              android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

Visit 'Replacing a fragment in a view pager', For view pager transactions. And when you are looking to study for fragments then visit-'http://developer.android.com/guide/components/fragments.html#Lifecycle'

I got doubt regarding Viewpager and Fragment .I want to create swipe view for that i need fragment classes with Viewpager .how could i implement such thing!!

i searched through net got something like this using viewpager!!

   public class ViewPagerFragmentActivity extends FragmentActivity {

    private PagerAdapter mPagerAdapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        super.setContentView(R.layout.viewpager_layout);

        // initialsie the pager
        this.initialisePaging();
    }

    /**
     * Initialize the fragments to be paged
     */
    private void initialisePaging() {

        List<Fragment> fragments = new Vector<Fragment>();
        fragments.add(Fragment.instantiate(this, Fragment0.class.getName()));
        fragments.add(Fragment.instantiate(this, Fragment1.class.getName()));
        fragments.add(Fragment.instantiate(this, Fragment2.class.getName()));
        this.mPagerAdapter = new MyPagerAdapter(super.getSupportFragmentManager(), fragments);

        ViewPager pager = (ViewPager) super.findViewById(R.id.viewpager);
        pager.setAdapter(this.mPagerAdapter);
    }
}

Manifest File:

 <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name="slider.example.ViewPagerFragmentActivity"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name="slider.example.Fragment0" android:theme="@android:style/Theme.NoTitleBar" android:screenOrientation="portrait" />
        <activity android:name="slider.example.Fragment1" android:theme="@android:style/Theme.NoTitleBar" android:screenOrientation="portrait" />
        <activity android:name="slider.example.Fragment2" android:theme="@android:style/Theme.NoTitleBar" android:screenOrientation="portrait" />
<activity android:name=".MyPagerAdapter"></activity>
    </application>

not add all classes in your activity, and then remember all classes are not activity. Where u use fragments as activity, so please study about Activity and what that differs from fragments,adapter classes and so on
Sino Raj about 11 years

Add one fragment,adapter and view pager on layout in your post/question
