java - 为什么我使用这个 android-lockpattern 库得到垃圾值作为我的输出？

Question

当我在 toast 中打印输出模式时，我正在为我的项目使用 android 锁定模式库，我得到所有垃圾值，如 [C245faa3a8

我从 https://code.google.com/p/android-lockpattern/ 得到了库和代码

这是我的代码。

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();
