Android ZXING条形码可以将结果值放在字符串中

  删除String声明，而不是将其作为类成员移动

  public void handleResult(Result result) {
              //String resultCode = result.getText();
               resultCode = result.getText();
  

  喜欢：

  myClass extends Activity... {
        String resultCode;
  }
  

  现在您可以在hadnleResult回调中分配结果代码，并在需要时在同一个活动中使用它！

  你有一个内部类，我会摆脱它并直接实现 ZXingScannerView.ResultHandler 接口：

  例：

  public class MainActivity extends AbsRuntimePermission  implements ZXingScannerView.ResultHandler{
  
      private String resultCode;
      private Button getBtn;
      private TextView result;
      private OkHttpClient client;
      boolean doubleTap = false;
      private ZXingScannerView scannerView;
      private static final int REQUEST_PERMISSION = 10;
      Toolbar toolbar;
  
  
      @Override
      protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_main);
          result = (TextView) findViewById(R.id.result);
          getBtn = (Button) findViewById(R.id.getBtn);
          getBtn.setOnClickListener(new View.OnClickListener() {
  
              @Override
              public void onClick(View v) {
                  getWebService();
              }
          });
          client = new OkHttpClient();
  
          Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
          setSupportActionBar(toolbar);
          requestAppPermissions(new String[]{
                          Manifest.permission.CAMERA},
                  R.string.msg, REQUEST_PERMISSION);
      }
  
      @Override
      public void onBackPressed() {
          if (doubleTap) {
              super.onBackPressed();
          } else {
              Toast.makeText(this, "Druk Terug opnieuw om de app te sluiten", Toast.LENGTH_SHORT).show();
              doubleTap = true;
              Handler handler = new Handler();
              handler.postDelayed(new Runnable() {
                  @Override
                  public void run() {
                      doubleTap = false;
                  }
              }, 500);
          }
      }
  
      @Override
      public boolean onCreateOptionsMenu(Menu menu) {
          // Inflate the menu; this adds items to the action bar if it is present.
          getMenuInflater().inflate(R.menu.menu_main, menu);
          return super.onCreateOptionsMenu(menu);
      }
  
      @Override
      public boolean onOptionsItemSelected(MenuItem item) {
          int id = item.getItemId();
          toolbar = (Toolbar) findViewById(R.id.toolbar);
  
          if (id == R.id.action_settings) {
              startActivity(new Intent(this, SettingsActivity.class));
              return true;
          }
          return super.onOptionsItemSelected(item);
      }
  
      public void browser1(View view) {
          Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.suppliance.nl/"));
          startActivity(browserIntent);
      }
  
      public void scanCode(View view) {
          scannerView = new ZXingScannerView(this);
          //scannerView.setResultHandler(new ZxingScannerResultHandler());
          scannerView.setResultHandler(this);
  
          setContentView(scannerView);
          scannerView.startCamera();
      }
  
      //class ZxingScannerResultHandler implements ZXingScannerView.ResultHandler {
          @Override
          public void handleResult(Result result) {
             // String resultCode = result.getText();
             // Toast.makeText(MainActivity.this, resultCode, Toast.LENGTH_SHORT).show();
              resultCode = result.getText();
              setContentView(R.layout.activity_main);
              Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
              setSupportActionBar(toolbar);
              scannerView.stopCamera();
          }
      //}
  
  
  
      private void getWebService() {
  
          Uri.Builder builder = new Uri.Builder();
          builder.scheme("http")
                  .appendPath(getString(R.string.ipadres))
                  .appendPath(getString(R.string.poort))
                  .authority("barcode/")
                  .appendPath(getString(R.id.))
          String URL = builder.build().toString();
  
          final Request request = new Request.Builder().url("http://192.168.17.12:9083/barcode/8712345501006").build();
          client.newCall(request).enqueue(new Callback() {
              @Override
              public void onFailure(Call call, IOException e) {
                  runOnUiThread(new Runnable() {
                      @Override
                      public void run() {
                          result.setText("Mislukt");
                      }
                  });
              }
  
              @Override
              public void onResponse(Call call, final Response response) {
                  runOnUiThread(new Runnable() {
                      @Override

                          } catch (IOException ioe) {

                          }
                      }

  我将使用此类似的东西，具体取决于您处理扫描仪视图的方式

  public class MainActivity extends AppCompatActivity 
                    implements ZXingScannerView.ResultHandler {
  
      private ZXingScannerView mScannerView;
      private String resultCode;
  
      @Override
      public void onCreate(Bundle state) {
          super.onCreate(state);
          mScannerView = new ZXingScannerView(this);   // Programmatically initialize the scanner view
          setContentView(mScannerView);                // Set the scanner view as the content view
      }
  
      @Override
      public void onResume() {
          super.onResume();
          mScannerView.setResultHandler(this); // Register ourselves as a handler for scan results.
          mScannerView.startCamera();          // Start camera on resume
      }
  
      @Override
      public void onPause() {
          super.onPause();
          mScannerView.stopCamera();           // Stop camera on pause
      }
  
      @Override
      public void handleResult(Result rawResult) {
          resultCode = rawResult.getText();
          //now use resultCode
      }
  }
