效果:
想看实例的,感兴趣的能够看之前的一篇文章
部分关键代码:
public class SerializeActivity extends Activity implements Serializable { Button btnlist, btnParcelable, btnSerialze; private final String TAG = "SerializeActivity"; public final static String LIST_KEY = "ArrayList"; public final static String PAR_KEY = "parcelable"; public final static String SER_KEY = "serializable"; private static final long serialVersionUID = 1L; private ArrayList<String> m_list; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_serialize); initView(); initlist(); } /* * 初始化视图 */ public void initView() { btnlist = (Button) findViewById(R.id.btnlist); btnParcelable = (Button) findViewById(R.id.btnParcelable); btnSerialze = (Button) findViewById(R.id.btnSerialze); btnlist.setOnClickListener(btnlistener); btnParcelable.setOnClickListener(btnlistener); btnSerialze.setOnClickListener(btnlistener); } public void initlist() { m_list = new ArrayList<String>(); m_list.add("www.88ios.com"); m_list.add("Android移动开发"); m_list.add("IOS开发入门"); } /* * button点击事件 */ OnClickListener btnlistener = new OnClickListener() { public void onClick(View v) { switch (v.getId()) { case R.id.btnlist: intentList(); break; case R.id.btnParcelable: intentParcelabe(); break; case R.id.btnSerialze: intentShowSer(); break; } } }; /* * */ public void intentList() { Intent list_intent = new Intent(); list_intent.putStringArrayListExtra(LIST_KEY, m_list); list_intent.setClass(SerializeActivity.this, ShowInfo.class); startActivity(list_intent); } /* * */ public void intentParcelabe() { Student m_Student = new Student(); m_Student.setName("88ios.com"); m_Student.setAge(25); m_Student.setSex("男"); Intent p_Intent = new Intent(SerializeActivity.this, ShowParcelabe.class); Bundle mBundle = new Bundle(); mBundle.putParcelable(PAR_KEY, m_Student); p_Intent.putExtras(mBundle); startActivity(p_Intent); } /* * */ public void intentShowSer() { final SerializableMap myMap = new SerializableMap(); List<Map<String, Object>> list = new ArrayList<Map<String, Object>>(); Map<String, Object> maplist; Map<String, Object> paramMap4 = new HashMap<String, Object>(); paramMap4.put("name", "洪生鹏"); paramMap4.put("website", "www.88ios.com"); paramMap4.put("address", "广州"); myMap.setMap(paramMap4); SerializableMap serializableMap = (SerializableMap) myMap; maplist = serializableMap.getMap(); list.add(maplist); Intent mIntent = new Intent(SerializeActivity.this, ShowSer.class); Bundle mBundle = new Bundle(); mBundle.putSerializable("map", (Serializable) myMap); //mBundle.putSerializable("map", (Serializable) list); mIntent.putExtras(mBundle); startActivity(mIntent); } }ShowInfo.java
