intent几种传值数组、对象、集合(Array,Object,List)

http://www.cnblogs.com/userbibi/archive/2012/03/29/2423202.html

1.Array

  

private  ArrayList checkList= new  ArrayList();

  Intent intent= new   Intent(mytext. this ,show. class );
  intent.putStringArrayListExtra( "list" , checkList);
  startActivity(intent);

　调用

 

Intent intent= this .getIntent();
 ArrayList list=intent.getStringArrayListExtra( "list" );
 ArrayList> mylist= new  ArrayList>();
 ///listview使用
 ListView listview=(ListView)findViewById(R.id.MyListView);
 for ( int  i= 0 ;i
 {
  HashMap map= new  HashMap();
  map.put( "ItemTitle" , list.get(i).toString());
  mylist.add(map);
 }

SimpleAdapter mSchedule= new  SimpleAdapter( this ,mylist,R.layout.show, new  String[]{ "ItemTitle" , "ItemTitle" }, new  int []{R.id.ItemTitle,R.id.ItemTitle});
listview.setAdapter(mSchedule);

　　

2.对象、列表（object,List）

前面都一样，上遍文章已经讲解，这边补充一下，只讲一个Serializable的。。另一个Parcelable都差不多，各自实现各自的接口，调用的时候可以不用那么麻烦，真心不喜欢用Bundle ,挺多此一举的

改写

如果是List

  List list=new  ArrayList();//搜索结果集合

Intent  intent= new  Intent(LinkMap. this ,MapList. class );
              intent.putExtra( "list" , (Serializable)list);
startActivity(intent);

这边直接强制转化就行了，再接受的时候用(List) getIntent().getSerializable("list")就可以接受到List数据了

Listlist=(List)getIntent().getSerializableExtra("list");

调用起来倒也方便的

具体调用,遍历代码

@Override
 public  void  onCreate(Bundle savedInstanceState) {

     super .onCreate(savedInstanceState);
     setContentView(R.layout.listmain);

  //   List list=(List)getIntent().getSerializableExtra("list");
     //创建适配器
     SimpleAdapter adapter = new  SimpleAdapter( this ,getData(),R.layout.maplist,
             new  String[]{ "name" , "kongwei" , "code" , "addr" },
             new  int []{R.id.name,R.id.kongwei,R.id.code,R.id.addr});

     setListAdapter(adapter);
  // ListView listview=(ListView)findViewById(R.id.SearchList);
//   listview.setAdapter(adapter);



     };


      private  List> getData() {
          List> list = new  ArrayList>();

          //获取参数
         List mylist=(List)getIntent().getSerializableExtra( "list" );

         for ( int  i= 0 ;i
         {
              Map map = new  HashMap();
             map.put( "name" ,mylist.get(i).getPrk_name());
             map.put( "kongwei" , "空位:" +mylist.get(i).getKongwei());
             map.put( "code" , "收费:" + mylist.get(i).getCode());
             map.put( "addr" , "地址:" +mylist.get(i).getPrk_addr());
              list.add(map);
           //   Toast.makeText(this, mylist.get(5).getPrk_name(), Toast.LENGTH_LONG).show();

         }

          return  list;
          }
