1.新建TestFragmen继承Fragment
public class TestFragment extends Fragment {private static final String TAG = "TestFragment";private String hello;// = "hello android";private String defaultHello = "default value";private Map<string, object=""> maplist;static TestFragment newInstance(String s, Map<string, object=""> map) {TestFragment newFragment = new TestFragment();// Bundle bundle = new Bundle();// bundle.putString("hello", s);// newFragment.setArguments(bundle);final SerializableMap myMap=new SerializableMap();myMap.setMap(map);Bundle bundle = new Bundle();bundle.putSerializable("map", myMap);newFragment.setArguments(bundle);return newFragment;}@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);Log.d(TAG, "TestFragment-----onCreate");Bundle args = getArguments(); // hello = args != null ? args.getString("hello") : defaultHello;Bundle bundle = getArguments();SerializableMap serializableMap = (SerializableMap) bundle.get("map");maplist =serializableMap.getMap();}@Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {Log.d(TAG, "TestFragment-----onCreateView");View view = inflater.inflate(R.layout.lay1, container, false);// TextView viewhello = (TextView) view.findViewById(R.id.tv_hello);//viewhello.setText(maplist.get("userid")+"time");ListView lv = (ListView) view.findViewById(R.id.listView3);ContactAdapter hc = new ContactAdapter(getActivity().getApplicationContext(),getContact());lv.setAdapter(hc);lv.setCacheColorHint(0);return view;}private ArrayList<contact> getContact(){ArrayList<contact> hcList = new ArrayList<contact>();for(int i=0;i<10;i++){Contact c0 = new Contact();c0.setTxPath(R.drawable.more_game+"");c0.setName(maplist.get("userid")+" 年龄:"+maplist.get("age"));hcList.add(c0);}return hcList;}@Overridepublic void onDestroy() {super.onDestroy();Log.d(TAG, "TestFragment-----onDestroy");}}</contact></contact></contact></string,></string,>2.MyFragmentPagerAdapter继承FragmentPagerAdapter
