intent几种传值数组、对象、集合(Array,Object,List)

1.Array

  

private ArrayList<String> checkList= new ArrayList<String>();       Intent intent= new  Intent(mytext. this ,show. class );    intent.putStringArrayListExtra( "list" , checkList);    startActivity(intent);

　调用

 

Intent intent= this .getIntent();   ArrayList<String> list=intent.getStringArrayListExtra( "list" );   ArrayList<HashMap<String,String>> mylist= new ArrayList<HashMap< String,String>>();   ///listview使用   ListView listview=(ListView)findViewById(R.id.MyListView);   for ( int i= 0 ;i<list.size();i++)   {    HashMap<String,String> map= new HashMap<String,String>();    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<Parking_Info> list=new  ArrayList<Parking_Info>();//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<Parking_Info>) getIntent().getSerializable("list")就可以接受到List<Parking_Info>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<Parking_Info> list=(List<Parking_Info>)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<Map<String, Object>> getData() {                   List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();                               //获取参数            List<Parking_Info> mylist=(List<Parking_Info>)getIntent().getSerializableExtra( "list" );                      for ( int i= 0 ;i<mylist.size();i++)           {                Map<String, Object> map = new HashMap<String, Object>();               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;            }
