java - Android 2.0 模拟器中奇怪的解析日期字符串错误

Question

我有一个简单的测试代码用于测试 SimpleDateFormat。此代码在 Eclipse 和 Android 1.5 模拟器上运行良好，但在 Android 2.0 模拟器上失败。有谁知道为什么？谢谢。

public class TemplateActivity extends Activity {
   /** Called when the activity is first created. */
   @Override
   public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       TextView tv = new TextView(this);
       tv.setText(R.string.hello);
       setContentView(tv);

       SimpleDateFormat format =
           new SimpleDateFormat("EEE, dd MMM yyyy HH:mm:ss zzz");

       String dateStr = "Mon, 17 May 2010 01:45:41 GMT"; 

       try {
           Date parsed = format.parse(dateStr);
           Log.v("Test", parsed.toString());
       } catch (ParseException pe) {
           Log.v("Test", "ERROR: Cannot parse \"" + dateStr + "\"");
       }

   }
}

日志消息:

V/Test(  400): ERROR: Cannot parse "Mon, 17 May 2010 01:45:41 GMT"

回复 Skrud，

我尝试了“EEE，dd MMM yyyy HH:mm:ss z”，但收到了相同的错误消息。

我也尝试过

SimpleDateFormat format =
       new SimpleDateFormat("EEE, dd MMM yyyy HH:mm:ss zzz", Locale.US);

它有效。但是系统每次调用都需要很长时间来加载 en_US 的时区名称:

I/Resources(  471): Loaded time zone names for en_US in 1904ms.
D/dalvikvm(  471): GC freed 10658 objects / 486232 bytes in 88ms
I/Resources(  471): Loaded time zone names for en_US in 1400ms.
I/Resources(  471): Loaded time zone names for en_US in 1260ms.

I/Resources(  471): Loaded time zone names for en_US in 1360ms.
I/Resources(  471): Loaded time zone names for en_US in 1232ms.

I/Resources(  471): Loaded time zone names for en_US in 1228ms.

我应该做什么？
