Java 如何获取条码扫描器android的活动结果？

如何使用zxing库获取自定义扫描仪的条形码扫描结果？“活动结果”不起作用。扫描部分工作正常，得到了满意的结果。但是我在活动结果中没有得到任何数据

public class ScannerActivity extends Activity implements ZXingScannerView.ResultHandler{

ResultHandler resultHandler;
Parameters parameters;
private CaptureManager capture;
private CompoundBarcodeView barcodeScannerView;
private Button switchFlashlightButton;
private ZXingScannerView mScannerView;
BarcodeView test;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_custom_scanner);

    Bundle extras = this.getIntent().getExtras();
    resultHandler = (ResultHandler) extras.getSerializable("RESULT_HANDLER");
    parameters = (Parameters) extras.getSerializable("PARAMETERS");

    barcodeScannerView = (CompoundBarcodeView)findViewById(R.id.zxing_barcode_scanner);
    this.getIntent().putExtra("Result_handle",resultHandler);
    capture = new CaptureManager(this, barcodeScannerView);
    capture.initializeFromIntent(getIntent(), savedInstanceState);
    capture.decode();
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
    Log.d("onActivityResult", "onActivityResult: .");
    if (resultCode == Activity.RESULT_OK) {
        IntentResult scanResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, intent);
        String re = scanResult.getContents();
        String message = re;
        Log.d("onActivityResult", "onActivityResult: ."+ re);
        Result handlerResult = new Result(Result.STATUS_SUCCESS, "qrcode", message);
        resultHandler.onHandleResult(handlerResult);
        this.finish();
    }
    // else continue with any other code you need in the method

}


@Override
protected void onResume() {
    Log.d("onResume", "onResume: .");
    super.onResume();
    capture.onResume();
}

@Override
protected void onPause() {
    Log.d("onPause", "onPause: .");
    super.onPause();
    capture.onPause();
}

@Override
protected void onDestroy() {
    super.onDestroy();
    capture.onDestroy();
}


@Override
protected void onSaveInstanceState(Bundle outState) {
    Log.d("onSaveInstanceState", "onSaveInstanceState: .");
    super.onSaveInstanceState(outState);
    capture.onSaveInstanceState(outState);
}

}

我解决了它。我就是这样做的

我创建了第二个活动CustomsCanneActivity。其中我做扫描部分

public class CustomScannerActivity extends Activity {

private CaptureManager capture;
private CompoundBarcodeView barcodeScannerView;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_custom_scanner);

    barcodeScannerView = (CompoundBarcodeView)findViewById(R.id.zxing_barcode_scanner);
    capture = new CaptureManager(this, barcodeScannerView);
    capture.initializeFromIntent(getIntent(), savedInstanceState);
    capture.decode();

}

@Override
protected void onResume() {
    super.onResume();
    capture.onResume();
}

@Override
protected void onPause() {
    super.onPause();
    capture.onPause();
}

@Override
protected void onDestroy() {
    super.onDestroy();
    capture.onDestroy();
}

@Override
protected void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    capture.onSaveInstanceState(outState);
}

}

然后从第一个活动开始。我从这一个调用了CustomScannerActivity。这样你就可以得到结果了。希望能有帮助。确保您也在清单中声明了活动，以便它能够工作

public class ScannerActivity extends Activity {

ResultHandler resultHandler;
Parameters parameters;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    IntentIntegrator integrator = new IntentIntegrator(this);
    integrator.setCaptureActivity(CustomScannerActivity.class);
    integrator.initiateScan();
}


@Override
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
    Log.d("onActivityResult", "onActivityResult: .");
    if (resultCode == Activity.RESULT_OK) {
        IntentResult scanResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, intent);
        String re = scanResult.getContents();
        String message = re;
        Log.d("onActivityResult", "onActivityResult: ." + re);
        Result handlerResult = new Result(Result.STATUS_SUCCESS, "qrcode", message);
        resultHandler.onHandleResult(handlerResult);
    }
    // else continue with any other code you need in the method
    this.finish();

}

您如何发送结果？请分享你的代码这是结果。但是它来自CaptureManager.java类，它是一个受库保护的void returnResult（BarcodeResult rawResult）{Intent Intent Intent=resultIntent（rawResult，getBarcodeImagePath（rawResult））；activity.setResult（activity.RESULT_OK，Intent）；finish（）；}我想知道是否会有冲突，因为你似乎在同一个活动中要求并收到结果。通常情况下，ActivityA将“startActivityForResult（ActivityA.this，ActivityB.class）”，然后ActivityB将（通过“getIntent（）”）确定它应该做什么，最后调用“setResult（）”和“finish（）”。最后将调用ActivityA的“onActivityResult（）”。如何发送结果？请分享你的代码这是结果。但是它来自CaptureManager.java类，它是一个受库保护的void returnResult（BarcodeResult rawResult）{Intent Intent Intent=resultIntent（rawResult，getBarcodeImagePath（rawResult））；activity.setResult（activity.RESULT_OK，Intent）；finish（）；}我想知道是否会有冲突，因为你似乎在同一个活动中要求并收到结果。通常情况下，ActivityA将“startActivityForResult（ActivityA.this，ActivityB.class）”，然后ActivityB将（通过“getIntent（）”）确定它应该做什么，最后调用“setResult（）”和“finish（）”。最后将调用ActivityA的“onActivityResult（）”。请不要在论坛上乱扔没有解决问题的答案。此应用程序中会有很多问题。。。。一个在manufesto文件中，另一个在接收结果时。。我只是举个例子告诉他。。。。并分享我的git链接以获得更多澄清。。。顺便说一句，谢谢你的建议…请不要在这个论坛上乱扔没有解决问题的答案。这个应用程序会有很多问题。。。。一个在manufesto文件中，另一个在接收结果时。。我只是举个例子告诉他。。。。并分享我的git链接以获得更多澄清。。。顺便说一下，谢谢你的建议。。。
