【移动开发】Android中Fragment+ViewPager的配合使用 推荐

原本在上一篇博客中要讲解一个Fragment的综合应用，但是中间又想到了滑屏方式，所以就分类在总结了一下

，(http://smallwoniu.blog.51cto.com/3911954/1308959)今天我将继续总结，关于Fragment+ViewPager的使用！

Fragment

FragmentPagerAdapter

FragmentStatePagerAdapter

FragmentPagerAdapter

和

[b]FragmentStatePagerAdapter

[b]这两个类都有简单的代码显示如何构建一个完整的用户界面与他们。

package com.zhf.android_viewpager_fragment;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
/**
* 自定义fragment适配器
* @author ZHF

*/
public class MyFragmentPageAdapter extends FragmentPagerAdapter {
public MyFragmentPageAdapter(FragmentManager fm) {
super(fm);
}
@Override
public int getCount() {
return 3;
}
@Override
public Fragment getItem(int position) {
switch (position) {
case 0:
return MyFragment.newInstance(position);
case 1:
return MyFragment.newInstance(position);
case 2:
return MyFragment.newInstance(position);
default:
return null;
}
}
}

package com.zhf.android_viewpager_fragment;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

/**
* 用于创建Fragment对象，作为ViewPager的叶片

*/
public class MyFragment extends Fragment {

int mNum; //页号
public static MyFragment newInstance(int num) {
MyFragment fragment = new MyFragment();
// Supply num input as an argument.
Bundle args = new Bundle();
args.putInt("num", num);
fragment.setArguments(args);
return fragment;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//这里我只是简单的用num区别标签，其实具体应用中可以使用真实的fragment对象来作为叶片
mNum = getArguments() != null ? getArguments().getInt("num") : 1;
}
/**为Fragment加载布局时调用**/
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {

View view = inflater.inflate(R.layout.fragment_pager_list, null);
TextView tv = (TextView) view.findViewById(R.id.text);
tv.setText("fragment+" + mNum);
return view;
}
}

package com.zhf.android_viewpager_fragment;

import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v4.view.ViewPager;

private ViewPager mViewPager;
private MyFragmentPageAdapter mAdapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mViewPager = (ViewPager) findViewById(R.id.viewpager);

//这里因为是3.0一下版本，所以需继承FragmentActivity，通过getSupportFragmentManager()获取FragmentManager
//3.0及其以上版本，只需继承Activity，通过getFragmentManager获取事物
FragmentManager fm = getSupportFragmentManager();
//初始化自定义适配器
mAdapter =  new MyFragmentPageAdapter(fm);
//绑定自定义适配器
mViewPager.setAdapter(mAdapter);
}
