爲什麼我得到垃圾值作爲我的輸出使用此android-lockpattern庫？

Question

我使用的是Android的鎖模式庫我的一個項目，當我打印舉杯輸出模式我得到的所有垃圾值，例如[C245faa3a8

我得到了圖書館和https://code.google.com/p/android-lockpattern/

這裏的代碼是我的代碼。

public class PatternTest extends Activity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 

     // TODO Auto-generated method stub 
     super.onCreate(savedInstanceState); 
     // This is your preferred flag 

     Intent intent = new Intent(LockPatternActivity.ACTION_CREATE_PATTERN, 
       null, getBaseContext(), LockPatternActivity.class); 
     startActivityForResult(intent, REQ_CREATE_PATTERN); 
    } 

    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     char[] pattern = null; 
     switch (requestCode) { 
     case REQ_CREATE_PATTERN: { 
      if (resultCode == RESULT_OK) { 
       pattern = data 
         .getCharArrayExtra(LockPatternActivity.EXTRA_PATTERN); 

      } 
      break; 
     }// REQ_CREATE_PATTERN 
     } 
     Toast.makeText(getApplicationContext(),pattern.toString(), 
       Toast.LENGTH_LONG).show(); 
    } 
}

使用new String(byte[])代替toString()：

Toast.makeText(getApplicationContext(),new String(pattern), 
      Toast.LENGTH_LONG).show();
