I tried the solution in this link, but this did not work for me. Error inflating class android.support.v4.view.ViewPager

activity_main.xml

 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context=".MainActivity" > <android.support.v4.app.ViewPager android:id="@+id/pager" android:layout_width="match_parent" android:layout_height="match_parent" /> </RelativeLayout> 

A fragment layout file consists of just one TextView . The fragment class is as follows:

 public class MyFragment extends Fragment{ int mCurrentPage; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); /** Getting the arguments to the Bundle object */ Bundle data = getArguments(); /** Getting integer data of the key current_page from the bundle */ mCurrentPage = data.getInt("current_page", 0); } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View v = inflater.inflate(R.layout.frag_layout, container,false); TextView tv = (TextView ) v.findViewById(R.id.tv); tv.setText("You are viewing the page #" + mCurrentPage + "\n\n" + "Swipe Horizontally left / right"); return v; } } 

FragmentPagerAdapter Class:

 public class MyAdapter extends FragmentPagerAdapter{ final int PAGE_COUNT = 3; public MyAdapter(FragmentManager fm) { super(fm); // TODO Auto-generated constructor stub } @Override public Fragment getItem(int arg0) { // TODO Auto-generated method stub MyFragment myFragment = new MyFragment(); Bundle data = new Bundle(); data.putInt("current_page", arg0+1); myFragment.setArguments(data); return myFragment; } @Override public int getCount() { // TODO Auto-generated method stub return PAGE_COUNT; } } 

primary occupation:

 public class MainActivity extends FragmentActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); ViewPager pager = (ViewPager) findViewById(R.id.pager); /** Instantiating FragmentPagerAdapter */ MyAdapter pagerAdapter = new MyAdapter(getSupportFragmentManager()); /** Setting the pagerAdapter to the pager object */ pager.setAdapter(pagerAdapter); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); return true; } }

Hi, I just made some changes to your layout file and now it works great.

 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:padding="10dp" > <android.support.v4.view.ViewPager android:id="@+id/pager" android:layout_width="fill_parent" android:layout_height="fill_parent" /> </RelativeLayout> 

you can check this:

The code below is only for your reservation ---->

Your main activity:

 package com.example.viewpage; import android.app.Activity; import android.os.Bundle; import android.support.v4.app.FragmentActivity; import android.support.v4.view.ViewPager; import android.view.Menu; public class MainActivity extends FragmentActivity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); ViewPager pager = (ViewPager) findViewById(R.id.pager); /** Instantiating FragmentPagerAdapter */ MyAdapter pagerAdapter = new MyAdapter(getSupportFragmentManager()); /** Setting the pagerAdapter to the pager object */ pager.setAdapter(pagerAdapter); } @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.activity_main, menu); return true; } } 

Myadapter:

 package com.example.viewpage; import android.os.Bundle; import android.support.v4.app.Fragment; import android.support.v4.app.FragmentManager; public class MyAdapter extends android.support.v4.app.FragmentPagerAdapter { final int PAGE_COUNT = 3; public MyAdapter(FragmentManager fm) { super(fm); // TODO Auto-generated constructor stub } @Override public Fragment getItem(int arg0) { // TODO Auto-generated method stub MyFragment myFragment = new MyFragment(); Bundle data = new Bundle(); data.putInt("current_page", arg0 + 1); myFragment.setArguments(data); return myFragment; } @Override public int getCount() { // TODO Auto-generated method stub return PAGE_COUNT; } } 

MyFragment:

 package com.example.viewpage; import android.os.Bundle; import android.support.v4.app.Fragment; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.TextView; public class MyFragment extends Fragment { private int mCurrentPage; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); /** Getting the arguments to the Bundle object */ Bundle data = getArguments(); /** Getting integer data of the key current_page from the bundle */ mCurrentPage = data.getInt("current_page", 0); } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View v = inflater.inflate(R.layout.frag_layout, container, false); TextView tv = (TextView) v.findViewById(R.id.textView1); tv.setText("You are viewing the page #" + mCurrentPage + "\n\n" + "Swipe Horizontally left / right"); return v; } } 

frag_layout.xml

 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" > <TextView android:id="@+id/textView1" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="Large Text" android:textAppearance="?android:attr/textAppearanceLarge" /> </LinearLayout> 

NOTE. add android-support-v4.jar to the lib folder. add this jar to the Build Path . go to project property-->Build Path--> Order & Export--> select all --> ok . Clear and run.
