具体描述：对准二维码或条形码扫描后，又跳转回扫描框界面（应该跳转到我的Activity），第二次扫描就跳转到我的Activity成功了；另外，我发现在扫描框出现后，我不去扫描选择点击返回，同样需要点击2遍才回到MainActivity。这是怎么回事，如何解决啊。(好像是ZXING3.2.1自带的问题，求解决)
以下是我的代码：
MainActivity下代码（是调用CaptureActivity获取到result，然后传递回我的MainActivity再跳转到ScanResultActivity获取结果）：
intent.setClass(MainActivity.this, CaptureActivity.class);
startActivityForResult(intent, 0);
protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) { final String result = data.getExtras().getString("result");
//定义一个handler对象 final android.os.Handler handler = new android.os.Handler() { public void handleMessage(Message msg) { if (msg.what == 1) {
RetValue retValue = (RetValue) msg.obj; //如果登录成功，转到查询明细 Intent intent = new Intent(MainActivity.this,ScanResultActivity.class);
Bundle data = new Bundle();
data.putString("totalqnty", retValue.getRetData().get(0).toString());
data.putString("detail", retValue.getRetData().get(1).toString()); //以下是查询明细所需条件 data.putString("bspno", result.toString());
intent.putExtras(data);
startActivity(intent);
}
}
}; //定义一个线程，在线程中运行webservice //开始验证登录帐号 new Thread(new Runnable() { @Override public void run() {
Message msg = new Message(); try {
RetValue retScanDetail = ws.GetBoxInfo(result.toString());
msg.obj = retScanDetail; //查询成功，继续获取相关的配置 if (Boolean.valueOf(retScanDetail.getRetValue().toString())) {
msg.what = 1;
} else {
msg.what = 0;
}
} catch (Exception e) {
msg.what = 0;
RetValue retScanDetail = new RetValue();
retScanDetail.setRetMsg(e.getMessage());
} handler.sendMessage(msg);
}
}).start();
}}
zxing CaptureActivity中 handleDecode下代码：
public void handleDecode(Result rawResult, Bitmap barcode, float scaleFactor) { inactivityTimer.onActivity(); beepManager.playBeepSoundAndVibrate();
Intent resultIntent = new Intent();
Bundle bundle = new Bundle();
bundle.putString("result", rawResult.getText());
resultIntent.putExtras(bundle); this.setResult(RESULT_OK, resultIntent);
CaptureActivity.this.finish();}
