数据的传递数据

---

第一种：

---

Intent intentSimple = new Intent();  intentSimple.setClass(MainActivity.this,SimpleActivity.class);  Bundle bundleSimple = new Bundle();  bundleSimple.putString("usr", "xcl");  bundleSimple.putString("pwd", "zj");  intentSimple.putExtras(bundleSimple);  startActivity(intentSimple); 

---

接收参数：

Bundle bunde = this.getIntent().getExtras();  String eml = bunde.getString("usr");  String pwd = bunde.getString("pwd");

---

第二种：

---

/传递复杂些的参数

Map<String, Object> map1 = new HashMap<String, Object>();  map1.put("key1", "value1");  map1.put("key2", "value2");  List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();  list.add(map1);  Intent intent = new Intent();  intent.setClass(MainActivity.this,ComplexActivity.class);  Bundle bundle = new Bundle(); 

---

ArrayList bundlelist = new ArrayList();   bundlelist.add(list);   bundle.putParcelableArrayList("list",bundlelist);  intent.putExtras(bundle);                startActivity(intent); 

---

接收参数：

---

Bundle bundle = getIntent().getExtras();            ArrayList list = bundle.getParcelableArrayList("list");
