android的Activity之间的数据传递(2)

25                 System.out.println("这里已经执行..."); 

26                 String txt = ""; 

27                 Bundle extras = data.getExtras(); 

28                 if(extras != null){ 

29                     txt = extras.getString("store"); 

30                 } 

31                 setTitle("这里是</SPAN><SPAN style="FONT-SIZE: 13px; LINE-HEIGHT: 19px; FONT-FAMILY: 'sans serif', tahoma, verdana, helvetica; WHITE-SPACE: normal; BACKGROUND-COLOR: #ffffff">Activity1</SPAN><SPAN>:" + txt); 

32             } 

33         } 

34     }</SPAN></P>

 这是Activity2中的代码：

view sourceprint?01 <SPAN>@Override

02     protected void onCreate(Bundle savedInstanceState) { 

03         super.onCreate(savedInstanceState); 

04         setTitle("这是activity2"); 

05         setContentView(R.layout.layout2); 

06         Bundle bundle = getIntent().getExtras(); 

07         if(bundle != null){ 

08             setTitle("这里是Activity2：" + bundle.getString("</SPAN><SPAN style="LINE-HEIGHT: 19px">activity1</SPAN>"));<SPAN>      } 

09           

10         Button btn = (Button) findViewById(R.id.btn2); 

11         btn.setOnClickListener(new Button.OnClickListener() { 

12             @Override

13             public void onClick(View v) { 

14                 Bundle bundle = new Bundle();
