Android Intent传递对象

Android中Intent中如何传递对象,就我目前所知道的有两种方法，一种是Bundle.putSerializable(Key,Object);另一种是Bundle.putParcelable(Key, Object);

本文只介绍好用的Serializable方法，想知道更多请自行百度。

第一步：新建一个类一个是Person.java实现Serializable接口

Person.java:

[java] view plaincopy

1. package com.tutor.objecttran;
2. import java.io.Serializable;
3. public class Person implements Serializable {
4. private static final long serialVersionUID = -7060210544600464481L;
5. private String name;
6. private int age;
7. public String getName() {
8. return name;
9. }
10. public void setName(String name) {
11. this.name = name;
12. }
13. public int getAge() {
14. return age;
15. }
16. public void setAge(int age) {
17. this.age = age;
18. }
20. }

第二步：发送对象

ObjectTranDemo.java:

[java] view plaincopy

1. package com.tutor.objecttran;
2. import android.app.Activity;
3. import android.content.Intent;
4. import android.os.Bundle;
5. import android.view.View;
6. import android.view.View.OnClickListener;
7. import android.widget.Button;
8. public class ObjectTranDemo extends Activity implements OnClickListener {
10. private Button sButton,pButton;
11. public final static String SER_KEY = "anystring";
12. public void onCreate(Bundle savedInstanceState) {
13. super.onCreate(savedInstanceState);
14. setContentView(R.layout.main);
15. setupViews();
17. }
19. //我的一贯作风呵呵
20. public void setupViews(){
21. sButton = (Button)findViewById(R.id.button1);
22. sButton.setOnClickListener(this);
23. }
24. 
    
25. //Serializeable传递对象的方法
26. public void SerializeMethod(){
27. Person mPerson = new Person();
28. mPerson.setName("H3c");
29. mPerson.setAge(23);
30. Intent mIntent = new Intent(this,ObjectTranDemo1.class);
31. Bundle mBundle = new Bundle();
32. mBundle.putSerializable(SER_KEY,mPerson);
33. mIntent.putExtras(mBundle);
35. startActivity(mIntent);
36. }
38. //铵钮点击事件响应
39. public void onClick(View v) {
40. SerializeMethod();
41. }
42. }

第三步：接收对象

ObjectTranDemo1.java:

[java] view plaincopy

1. package com.tutor.objecttran;
2. import android.app.Activity;
3. import android.os.Bundle;
4. import android.widget.TextView;
5. public class ObjectTranDemo1 extends Activity {
6. @Override
7. public void onCreate(Bundle savedInstanceState) {
8. super.onCreate(savedInstanceState);
10. TextView mTextView = new TextView(this);
11. Person mPerson = (Person)getIntent().getSerializableExtra(ObjectTranDemo.SER_KEY);
12. mTextView.setText("You name is: " + mPerson.getName() + "/n"+
13. "You age is: " + mPerson.getAge());
15. setContentView(mTextView);
16. }
17. }
