android串行化getSerializable、getSerializableExtra

android串行化getSerializable、getSerializableExtra 传参 总结

案例1 不用 Bundle 封装数据

提交activity

 lst.setOnItemClickListener(new OnItemClickListener() {

    public void onItemClick(AdapterView<?> parent, View view,

      int position, long id) {

     HashMap map=(HashMap) parent.getItemAtPosition(position);

     Intent intent=new Intent();

     intent.setClass(btsAllinfoActivity.this,btsMapActivity.class);

     intent.putExtra("bts_map", map);

     startActivity(intent);

    }

   });

接收数据activity

Intent intent=getIntent();

map=(HashMap)intent.getSerializableExtra("bts_map");

  System.out.println("");

  System.out.println(map.get("bt_id"));

  System.out.println(map.get("bt_name"));

  System.out.println(map.get("bt_lon"));

  System.out.println(map.get("bt_lat"));

  System.out.println("");
 

案例二 用Bundle封装数据

提交activity

HashMap map=(HashMap) parent.getItemAtPosition(position);

     Intent intent=new Intent();

     intent.setClass(btsAllinfoActivity.this,btsMapActivity.class);

     Bundle bundle = new Bundle();

     bundle.putSerializable("bts_map", map);

     intent.putExtras(bundle);

     startActivity(intent);

接收activity

Bundle bundle = getIntent().getExtras();

  map=(HashMap)bundle.getSerializable("bts_map");

  System.out.println("");

  System.out.println(map.get("bt_id"));

  System.out.println(map.get("bt_name"));

  System.out.println(map.get("bt_lon"));

  System.out.println(map.get("bt_lat"));

  System.out.println("");
