Android ViewPager Example

Hello Friends Today I will write code for View pager in fragment not in fragment activity.

Step 1 : MainActivity.java

package com.ritesh.viewpagerdemo;

import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentTransaction;

public class MainActivity extends FragmentActivity {

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

FragmentManager fm=getSupportFragmentManager();
FragmentTransaction ft=fm.beginTransaction();
ft.add(R.id.mainlayout, new FragmentMain());
ft.commit();

}


}

Step 2 : activity_main.xml

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="fill_parent"

    android:layout_height="fill_parent"

    android:id="@+id/mainlayout" >

</FrameLayout>

Step 3 : FragmentMain.java

package com.ritesh.viewpagerdemo;

import android.os.Bundle;

import android.support.v4.app.Fragment;

import android.support.v4.view.ViewPager;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

public class FragmentMain extends Fragment

{

public View onCreateView(LayoutInflater inflater, ViewGroup container,

Bundle savedInstanceState) {

// TODO Auto-generated method stub

return inflater.inflate(R.layout.fragmentmain, container, false);

}

      @Override

      public void onActivityCreated(Bundle savedInstanceState) {

 // TODO Auto-generated method stub

 super.onActivityCreated(savedInstanceState);

ViewPager pager = (ViewPager)getActivity().findViewById(R.id.viewPager);

pager.setAdapter(new MyPagerAdapter(getActivity().getSupportFragmentManager()));

      }

}

Step 4 : fragmentmain.xml

<android.support.v4.view.ViewPager

    xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:app="http://schemas.android.com/apk/res-auto"

    android:id="@+id/viewPager"

    android:layout_width="fill_parent"

    android:layout_height="fill_parent"

    />

Step 5:  MyPagerAdapter.java

package com.ritesh.viewpagerdemo;

import android.support.v4.app.Fragment;

import android.support.v4.app.FragmentManager;

import android.support.v4.app.FragmentPagerAdapter;

public class MyPagerAdapter extends FragmentPagerAdapter

{

public MyPagerAdapter(FragmentManager fm) {

super(fm);

// TODO Auto-generated constructor stub

}

@Override

public Fragment getItem(int position) {

switch (position) {

case 0:

return  NewsFragment.newInstance();

case 1:

return  AudioFragment.newInstance();

     }

return null;

}

@Override

public int getCount() {

// TODO Auto-generated method stub

return 2;

}

}

Step 6 : AudioFragment.java

package com.ritesh.viewpagerdemo;

import android.os.Bundle;

import android.support.v4.app.Fragment;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

public class AudioFragment extends Fragment

{

public View onCreateView(LayoutInflater inflater, ViewGroup container,

Bundle savedInstanceState) {

// TODO Auto-generated method stub

return inflater.inflate(R.layout.audio, container, false);

}

@Override

public void onActivityCreated(Bundle savedInstanceState) {

// TODO Auto-generated method stub

super.onActivityCreated(savedInstanceState);

 }

public static Fragment newInstance() {

// TODO Auto-generated method stub

return new AudioFragment();

}

}

Step 7 :  audio.xml

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    android:orientation="vertical" >

    <TextView

        android:id="@+id/textaudio"

        android:layout_width="fill_parent"

        android:layout_height="fill_parent"

        android:layout_alignParentTop="true"

        android:layout_centerHorizontal="true"

        android:textColor="#00FF00"

        android:gravity="center"

        android:textSize="25sp"

        android:background="@android:color/black"

        android:textStyle="bold"

        android:text="Audio" />

</RelativeLayout>

Step 8 : NewsFragment.java

package com.ritesh.viewpagerdemo;

import android.os.Bundle;

import android.support.v4.app.Fragment;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

public class NewsFragment  extends Fragment

 {

 public View onCreateView(LayoutInflater inflater, ViewGroup container,

Bundle savedInstanceState) {

// TODO Auto-generated method stub

return inflater.inflate(R.layout.news, container, false);

    }

 @Override

 public void onActivityCreated(Bundle savedInstanceState) {

// TODO Auto-generated method stub

super.onActivityCreated(savedInstanceState);

      }

 public static Fragment newInstance() {

// TODO Auto-generated method stub

return new NewsFragment();

    }

   }

Step 9 :  news.xml

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    android:orientation="vertical" >

    <TextView

        android:id="@+id/textnews"

        android:layout_width="fill_parent"

        android:layout_height="fill_parent"

        android:layout_alignParentTop="true"

        android:layout_centerHorizontal="true"

        android:textStyle="bold"

        android:textColor="#00FF00"

        android:gravity="center"

        android:textSize="25sp"

        android:background="@android:color/black"

        android:text="News" />

</RelativeLayout>
