关于使用handle产生The Application has stopped unexpectedly的问题

[lvcn]

源代码如下：

package game.showhand;

import java.util.Timer;   
import java.util.TimerTask; 
import android.app.Activity;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.widget.TextView;

public class showhand extends Activity {
	 /** Called when the activity is first created. */


	 

    @Override
    public void onCreate(Bundle savedInstanceState) {
    	
        super.onCreate(savedInstanceState);       
        setContentView(R.layout.main); 
        final Handler handler = new Handler()
        {  
        	int recLen;
        	TextView recTime = new TextView(showhand.this);
       	@Override
        public void handleMessage(Message msg) 
        {  
        switch (msg.what)
        {      
         case 1:      
         recLen++;
         recTime.setText(recLen);
        break;      
        }      
         super.handleMessage(msg);  
        }    
        };
        TimerTask task = new TimerTask(){  
            public void run() {  
            Message message = new Message();      
            message.what = 1;      
            handler.sendMessage(message);    
            }  
            }; 
        Timer timer = new Timer(true);
        timer.schedule(task,1000, 1000);
    	
        
    }


}

一个简单的例子：

1. package com.ray.test;
2.
3. import java.util.Timer;
4. import java.util.TimerTask;
5.
6. import android.app.Activity;
7. import android.os.Bundle;
8. import android.os.Handler;
9. import android.os.Message;
10.
11. public class TestTimer extends Activity {
12.
13. Timer timer = new Timer();
14. Handler handler = new Handler(){
15.
16. public void handleMessage(Message msg) {
17. switch (msg.what) {
18. case 1:
19. setTitle("hear me?");
20. break;
21. }
22. super.handleMessage(msg);
23. }
24.
25. };
26. TimerTask task = new TimerTask(){
27.
28. public void run() {
29. Message message = new Message();
30. message.what = 1;
31. handler.sendMessage(message);
32. }
33.
34. };
35. public void onCreate(Bundle savedInstanceState) {
36. super.onCreate(savedInstanceState);
37. setContentView(R.layout.main);
38. timer.schedule(task, 10000);
39. }
40. }

楼上的是高手，现在有事，我是做php开发的，先完成早上的任务，下午没事了，我调试好就把分给你

public void handleMessage(Message msg)
{
switch (msg.what)
{
case 1:
recLen++;
recTime.setText(recLen);
break;
}


这段中recTime.setText(recLen);出错。recLen为int值，系统会到res去找对应的String，但是没有，所以报resources not found的错误。

建议将其改成：
recTime.setText(String.valueOf(recLen));

就一切OK了。
