为什么我的程序总是挂掉？求解

package com.example.viewpager;

import android.os.Bundle;

import android.support.v4.app.Fragment;

import android.support.v4.app.FragmentActivity;

import android.support.v4.app.FragmentManager;

import android.support.v4.app.FragmentPagerAdapter;

import android.support.v4.app.FragmentStatePagerAdapter;

import android.support.v4.view.ViewPager;

import android.view.ViewGroup;

import android.view.Window;

public class MainActivity extends FragmentActivity {
private int[] layouts={R.layout.page1,R.layout.page2,R.layout.page3};
private ViewPager viewPager;
MyAdapter adapter ;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_main);
viewPager = (ViewPager)findViewById (R.id.vp);
adapter =new MyAdapter(getSupportFragmentManager());

//页面滑动器,调用TranslatePageTransformer函数的transformPage方法，实现页面子控件的加速效果
// viewPager.setPageTransformer(true, new TranslatePageTransformer());

viewPager.setAdapter(adapter);//加入适配器
}

class MyAdapter extends FragmentStatePagerAdapter{//适配器切换Fragment
public MyAdapter(FragmentManager fm){
super(fm);
}

        @Override
public Fragment getItem(int position){
Fragment f =new TranslationFragment();
Bundle bundle=new Bundle();
bundle.putInt("layoutId",layouts[position]);
f.setArguments(bundle);
return f;
}
