结对项目——电子书ViewPager功能

该功能实现了界面引导

public class ViewPagerActivity extends FragmentActivity {
private ViewPager mVPActivity;
private Fragment1 mFragment1;
private Fragment2 mFragment2;
private Fragment3 mFragment3;
private Fragment4 mFragment4;
private List mListFragment = new ArrayList();
private PagerAdapter mPgAdapter;

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

private void initView() {
	mVPActivity = (ViewPager) findViewById(R.id.vp_activity);
	mFragment1 = new Fragment1();
	mFragment2 = new Fragment2();
	mFragment3 = new Fragment3();
	mFragment4 = new Fragment4();
	mListFragment.add(mFragment1);
	mListFragment.add(mFragment2);
	mListFragment.add(mFragment3);
	mListFragment.add(mFragment4);
	mPgAdapter = new ViewPagerAdapter(getSupportFragmentManager(),
			mListFragment);
	mVPActivity.setAdapter(mPgAdapter);
}

}

ViewPager适配器代码如下所示
public class ViewPagerAdapter extends FragmentPagerAdapter {
private List fragmentList=new ArrayList();
public ViewPagerAdapter(FragmentManager fm) {
super(fm);
}
public ViewPagerAdapter(FragmentManager fragmentManager,List arrayList) {
super(fragmentManager);
this.fragmentList=arrayList;
}
@Override
public Fragment getItem(int arg0) {
return fragmentList.get(arg0);
}

@Override
public int getCount() {
	return fragmentList.size();
}

}
