采用Viewpager+Fragment实现

import android.support.annotation.NonNull;

import android.support.v4.app.Fragment;

import android.support.v4.app.FragmentManager;

import android.support.v4.app.FragmentPagerAdapter;

import android.support.v4.view.ViewPager;

import android.view.ViewGroup;

import java.util.ArrayList;

import java.util.List;

public class FragmentAdapter extends FragmentPagerAdapter {

private final List mFragmentSet = new ArrayList<>();

private F mCurrentFragment;

private ViewPager mViewPager;

public BaseFragmentAdapter(FragmentManager fm) {

super(fm);

}

@SuppressWarnings("unchecked")

@Override

public void setPrimaryItem(@NonNull ViewGroup container, int position, @NonNull Object object) {

if (getCurrentFragment() != object) {

// 记录当前的Fragment对象

mCurrentFragment = (F) object;

}

super.setPrimaryItem(container, position, object);

}

public void addFragment(F fragment) {

mFragmentSet.add(fragment);

}

@Override

public void startUpdate(@NonNull ViewGroup container) {

super.startUpdate(container);

if (container instanceof ViewPager) {

// 记录绑定 ViewPager

mViewPager = (ViewPager) container;

}

}

public void setCurrentItem(int position) {

if (mViewPager != null) {

mViewPager.setCurrentItem(position);

}

}

public void setCurrentItem(int position, boolean smoothScroll) {

if (mViewPager != null) {

mViewPager.setCurrentItem(position, smoothScroll);

}

}

------------------- 此处更多代码略 -------------------

}

BaseFragmentAdapter mPagerAdapter = new BaseFragmentAdapter<>(getSupportFragmentManager());

mPagerAdapter.addFragment(new FragmentA());

mPagerAdapter.addFragment(new FragmentB());

mPagerAdapter.addFragment(new FragmentC());

mPagerAdapter.addFragment(new FragmentD());

ViewPager mViewPager ;

mViewPager .setAdapter(mPagerAdapter);

// 限制页面数量

mViewPager .setOffscreenPageLimit(mPagerAdapter.getCount());
