1.自定义Pager，设置要返回的View的方法为抽象方法，并将返回的View

2.设置ViewPager的Adapter

关键代码如下：

public  abstract  class BasePager {    public Activity mActivity;    public final View view;    public BasePager(Activity mActivity) {        this.mActivity = mActivity;        view = View.inflate(mActivity, R.layout.view_base_pager, null);        FrameLayout flBase = (FrameLayout) view.findViewById(R.id.fl_base_pager);        //将子类必须要实现的方法中返回的View填充到FrameLayout        flBase.addView(initView());    }    //定义为抽象方法，子类继承该类必须要实现的方法    public  abstract  View initView();    //子类继承该类可实现也可不实现    public void initData() {    }}

public class VPAdapter extends PagerAdapter {    private Context mContext;    private List<BasePager> mPagers;    public VPAdapter(Context mContext, List<BasePager> mPagers) {        this.mContext = mContext;        this.mPagers = mPagers;    }    @Override    public int getCount() {        return mPagers.size();    }    @Override    public boolean isViewFromObject(View view, Object object) {        return view==object;    }    @Override    public Object instantiateItem(ViewGroup container, int position) {        BasePager basePager = mPagers.get(position);        container.addView(basePager.view);        return basePager.view;    }    @Override    public void destroyItem(ViewGroup container, int position, Object object) {       container.removeView((View) object);    }}

mVpContent.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {            @Override            public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {            }            @Override            public void onPageSelected(int position) {                BasePager basePager = pagers.get(position);                basePager.initData();            }            @Override            public void onPageScrollStateChanged(int state) {            }        });

public class HomePager extends BasePager {    public HomePager(Activity context) {        super(context);    }    @Override    public View initView() {        TextView tv=new TextView(mContext);        tv.setText("首页");        tv.setTextColor(Color.RED);        tv.setTextSize(20);        tv.setGravity(Gravity.CENTER);        return tv;    }    @Override    public void initData() {        L.d("首页:initData");        mTvHeadTitle.setText("首页");        mIvMenu.setVisibility(View.GONE);    }}
