Question

我已将ZXing代码集成到我的应用中。我被告知不要将整个图像复制并粘贴到我的应用程序中，而是采取我需要的部分。我从捕获活动开始，然后将其依赖项复制到我的应用程序中。我将意图过滤器从zxing改为了我的意图过滤器。哦，我必须在capture.xml中更改包名称。

似乎工作正常，当我的活动调用startActivityForResult（）扫描程序启动时。问题是当我扫描QRcode时，扫描结果不会传播回我的调用活动，而是询问如何完成动作，例如短信，电子邮件等。

如何让扫描结果回到我的活动onActivityResult？

先谢谢了

 Button signin = (Button)findViewById(R.id.buttonsignin);

        alpha = new AlphaAnimation(0.3F, 0.8F); //Set opacity - Range 0.0 to 1.0
        alpha.setDuration(0); // Set animation duration
        alpha.setFillAfter(true); // Maintaining the effect to the button
        signin.startAnimation(alpha);
        signin.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                Log.e(TAG, "onclicked sign in");

                Intent intent = new Intent(
                        "com.carefreegroup.SCAN");
                intent.putExtra("SCAN_MODE", "QR_CODE_MODE");

                startActivityForResult(intent, 0);

            }
        });

public void onActivityResult(int requestCode, int resultCode, Intent intent) {
        Log.e(TAG, "in onActivityResult");
        if (requestCode == 0) {
