机器人：zxing吧code扫描成功，但是从活动没有返回 [英] android: zxing barcode scan successful but not returning from activity

问题描述

我成功地利用zxing扫描codeS，通过调用安装吧code读者的意图，但是当它发出蜂鸣声，并表示了良好的扫描我希望zxing活动将返回控制，所以我可以处理结果，但坐在那里，并尝试重新扫描。我要preSS后退按钮和然后的返回，我可以做下一步。有一些明显的标志，我很想念我的时候调用扫描仪？

任何建议感激地接受。非常感谢。

下面是我的code：

 公共布尔的onTouchEvent（最终MotionEvent事件）{

    意向意图=新的意图（com.google.zxing.client.android.SCAN）;
    intent.putExtra（com.google.zxing.client.android.SCAN.SCAN_MODE，QR_ code_MODE）;
    startActivityForResult（意向，0）;

    返回true;
    }

公共无效onActivityResult（INT申请code，INT结果code，意图意图）{

    super.onActivityResult（要求code，因此code，意图）;

    如果（要求code == 0）{
        如果（结果code == RESULT_OK）{
            字符串内容= intent.getStringExtra（SCAN_RESULT）;
            字符串格式= intent.getStringExtra（SCAN_RESULT_FORMAT）;

            //处理成功的扫描

            字符串s =htt​​p://www.google.com/search?q=;
            S + =内容;
            意图myIntent1 =新的意图（Intent.ACTION_VIEW，Uri.parse（S））;
            startActivity（myIntent1）;
            }
        其他
            如果（结果code == RESULT_CANCELED）{
                //处理取消
                }
            }
        }
    }
 

解决方案

为什么不使用所提供的 IntentIntegrator 类？这是在项目文档中提到的唯一办法，你看看那些？ HTTP：//$c$c.google.com/p/zxing/wiki / ScanningViaIntent

我创造了它包裹起来发送和解析意向的这些细节，所以你不把错别字。例如，有没有这样的东西作为额外的com.google.zxing.client.android.SCAN.SCAN_MODE。

I am successfully using zxing to scan codes, by calling the installed barcode reader's intent, but when it beeps and indicates a good scan I expect the zxing activity would return control so I can process the result, but it sits there and tries to scan again. I have to press the back button and then it returns and I can do the next step. Is there some obvious flag I'm missing when I call the scanner?

Any advice gratefully received. Many thanks.

Here's my code:

public boolean onTouchEvent(final MotionEvent event) {

    Intent intent = new Intent("com.google.zxing.client.android.SCAN");
    intent.putExtra("com.google.zxing.client.android.SCAN.SCAN_MODE", "QR_CODE_MODE");
    startActivityForResult(intent, 0);

    return true;
    }

public void onActivityResult(int requestCode, int resultCode, Intent intent) {

    super.onActivityResult(requestCode, resultCode, intent);

    if (requestCode == 0) {
        if (resultCode == RESULT_OK) {
            String contents = intent.getStringExtra("SCAN_RESULT");
            String format = intent.getStringExtra("SCAN_RESULT_FORMAT");

            // Handle successful scan

            String s = "http://www.google.com/search?q=";
            s += contents;
            Intent myIntent1 = new Intent(Intent.ACTION_VIEW, Uri.parse(s));
            startActivity(myIntent1);
            }
        else 
            if (resultCode == RESULT_CANCELED) {
                // Handle cancel
                }
            }
        }
    }

解决方案

Why not use the provided IntentIntegrator class? This is the only approach mentioned in the project docs, did you have a look at those? http://code.google.com/p/zxing/wiki/ScanningViaIntent

I created it to wrap up these details of sending and parsing the Intent, so you don't make typos. For example, there's no such thing as extra "com.google.zxing.client.android.SCAN.SCAN_MODE".
