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;

          }
