1、新建super

//super提供统一的FragmentActivity入口。 public abstract class SuperFragmentActivity extends FragmentActivity {
      @Override     protected void onCreate(@Nullable Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);         setContentView(R.layout.fragmentlistactivity);         FragmentManager fm=getSupportFragmentManager();         Fragment fragment=fm.findFragmentById(R.id.mainfragment);         if (fragment == null){
              fragment=createFragment();             fm.beginTransaction().add(R.id.mainfragment,fragment).commit();         }     }     public abstract Fragment createFragment(); } //接上一个项目，创建好列表 //FragmentListActivity

public class FragmentListActivity extends SuperFragmentActivity{
      @Override     public Fragment createFragment() {//实现super中的方法         return new StudentListFragment();     } } //创建ListFragment

public class StudentListFragment extends Fragment implements View.OnClickListener {
      private TextView mNameTextView;     private TextView mAgeTextView;     private List
    
      mStudents;     private Student mStudent;     @Nullable     @Override     public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
          super.onCreateView(inflater, container, savedInstanceState);         View view=inflater.inflate(R.layout.recyclistview, container,false);         RecyclerView recyclerView= (RecyclerView) view.findViewById(R.id.recycleview);//Fragment绑定RecycleView         recyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));         recyclerView.setAdapter(new RecycleAdpter());         return view;     }     @Override     public void onClick(View v) {
          startActivity(viewpageActivity.newIntent(getActivity(),mStudent.getNum()));//当被点击时启动启动另一个FragmentActivity     }     private class RecycleAdpter extends RecyclerView.Adapter
     
       {
      @Override     public RecyclerViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
          LayoutInflater inflater=LayoutInflater.from(getActivity());         View v=inflater.inflate(R.layout.studentview,parent,false);         return new RecyclerViewHolder(v);     }     @Override     public void onBindViewHolder(RecyclerViewHolder holder, int position) {
          mStudent=mStudents.get(position);         mNameTextView.setText(mStudent.getName());         mAgeTextView.setText(mStudent.getAge()+"");     }     @Override     public int getItemCount() {
          mStudents=StudentList.get();         return mStudents.size();     } }     private class RecyclerViewHolder extends RecyclerView.ViewHolder{
          public RecyclerViewHolder(View itemView) {
              super(itemView);             mAgeTextView= (TextView) itemView.findViewById(R.id.age_textview);             mNameTextView= (TextView) itemView.findViewById(R.id.name_textview);             itemView.setOnClickListener(StudentListFragment.this);         }     } }
     
    

2、FragmentActivity绑定ViewPage

public class ViewpageActivity extends FragmentActivity {
      private static final String EXTRA_INDEX = "com.example.ting.criminalintentpractise.viewpage";     private ViewPager mViewPager;     private List
    
      mStudentList;     @Override     protected void onCreate(@Nullable Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);         setContentView(R.layout.activity_viewpage);          mViewPager = (ViewPager) findViewById(R.id.viewpage);         FragmentManager fm = getSupportFragmentManager();         int num = getIntent().getIntExtra(EXTRA_INDEX, 0);         mStudentList=StudentList.get();         mViewPager.setAdapter(new FragmentStatePagerAdapter(fm) {//将样式文件中的viewpager绑定到一个fragment             @Override 　　　　　　　　//滚动的位置             public Fragment getItem(int position) {                 return StudentFragment.newInstance(position);             }             @Override 　　　　　　　　//总的滚动页数             public int getCount() {
                  return StudentList.get().size();             }         });         mViewPager.setCurrentItem(num); //设置滚动起始页     }     public static Intent newIntent(Context context, int index) {
          Intent intent = new Intent(context, ViewpageActivity.class);         intent.putExtra(EXTRA_INDEX, index);         return intent;     } } 3、新建Fragment
    

public class StudentFragment extends Fragment {
      private TextView mNameTextView;     private TextView mAgeTextView;     private static String ARG_INDEX = "com.example.ting.criminalintentpractise.student";     private int num;     @Nullable     @Override     public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
          super.onCreateView(inflater, container, savedInstanceState);         View v = inflater.inflate(R.layout.studentview, container, false);//启动自身的样式文件         mNameTextView = (TextView) v.findViewById(R.id.name_textview);         mAgeTextView = (TextView) v.findViewById(R.id.age_textview);         List
    
      list = StudentList.get();         mNameTextView.setText(list.get(num).getName());         mAgeTextView.setText(list.get(num).getAge()+"");         return v;     } //为启动该Fragment封装启动参数     public static StudentFragment newInstance(int index) {
          Bundle bundle = new Bundle();         bundle.putInt(ARG_INDEX, index);         StudentFragment fragment = new StudentFragment();         fragment.setArguments(bundle);//通过Arguments将参数传入Fragment         return fragment;     }     @Override     public void onCreate(@Nullable Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);         num = getArguments().getInt(ARG_INDEX); //接收Activity传入的参数     } }
    

4、心得 Intent和Arguments和Bundle关系 1、Activity间相互传质使用Intent。 2、Activity和Fragment间传值使用Arguments。 3、Intent和Arguments传值都是封装在Bundle中进行的，Bundle是Intent和Argument传值的载体。
