1.实现适配器
public class FragAdapter extends FragmentPagerAdapter {
private List<Fragment> list_fragment;
private List<String> list_title;
public FragAdapter(FragmentManager fm,List<Fragment> list_fragment,List<String> list_title) {
super(fm);
this.list_fragment=list_fragment;
this.list_title=list_title;
}
@Override
public Fragment getItem(int position) {
return list_fragment.get(position);
}
@Override
public int getCount() {
return list_title.size();
}
@Override
public CharSequence getPageTitle(int position) {
return list_title.get(position%list_title.size()); }}
2.按照自己的需求创建Fragment
public class Fragment2 extends Fragment {
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view=inflater.inflate(R.layout.frag2,container,false); List<ItemBean> list=new ArrayList<>();
for(int i=0;i<200;i++){
list.add(new ItemBean(
R.mipmap.ic_launcher,
"标题",
"内容" ));
}
MyAdapter adapter=new MyAdapter(getActivity(),list);
ListView listView=(ListView)view.findViewById(R.id.listview);
listView.setAdapter(adapter);
return view; }}
需要注意的是:
MyAdapter adapter=new MyAdapter(getActivity(),list);
这里通过getActivity()获取页面的context
3.设置ListView的适配器和容器
之前已经写过类似的所以不再重复
4.主界面
public class MainActivity extends FragmentActivity {
private TabLayout tab_FindFragment_title;
private ViewPager vp_FindFragment_pager;
private FragAdapter fAdapter;
private List<Fragment> list_fragment;
private List<String> list_title;
private Fragment1 fragment1;
private Fragment2 fragment2;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tab_FindFragment_title=(TabLayout)findViewById(R.id.tab_FindFragment_title); vp_FindFragment_pager=(ViewPager)findViewById(R.id.vp_FindFragment_pager);
fragment1=new Fragment1();
fragment2=new Fragment2();
list_fragment=new ArrayList<>();
list_fragment.add(fragment1);
list_fragment.add(fragment2);
list_title=new ArrayList<>();
list_title.add("aaa");
list_title.add("bbb");
tab_FindFragment_title.setTabMode(TabLayout.MODE_FIXED);
tab_FindFragment_title.addTab(tab_FindFragment_title.newTab().setText(list_title.get(0)));
tab_FindFragment_title.addTab(tab_FindFragment_title.newTab().setText(list_title.get(1)));
fAdapter=new
FragAdapter(getSupportFragmentManager(),list_fragment,list_title);
vp_FindFragment_pager.setAdapter(fAdapter);
tab_FindFragment_title.setupWithViewPager(vp_FindFragment_pager); }}
步骤:
1.添加fragment对象到fragment列表
2.添加title到title列表
3.从title列表中取出内容放到tabLayout容器中
4.创建并初始化适配器
5.为viewPager设定适配器
6.通过tab_FindFragment_title.setupWithViewPager(vp_FindFragment_pager
将TabLayout和ViewPager关联起来
