Question

大家好我正在制作像扫描条形码和二维码一样的android项目，我完成了扫描部分，任何人都可以告诉我如何在出现结果对话后将结果存储在文本视图中。谢谢这是我的代码：

public class MainActivity extends AppCompatActivity implements ZXingScannerView.ResultHandler {

    private ZXingScannerView mScannerView;
    Button scan_code;
    private static final int CAMERA_REQUEST = 1888;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        scan_code = (Button) findViewById(R.id.button);

    }

    public void QrScanner(View view){

        mScannerView = new ZXingScannerView(this);   // Programmatically initialize the scanner view
        setContentView(mScannerView);
        mScannerView.setResultHandler(this); // Register ourselves as a handler for scan results.
        mScannerView.startCamera();         // Start camera
    }

    @Override
    public void onPause() {
        super.onPause();
        mScannerView.stopCamera();   // Stop camera on pause
    }

    @Override
    public void handleResult(Result rawResult) {
        // Do something with the result here

        Log.e("handler", rawResult.getText()); // Prints scan results
        Log.e("handler", rawResult.getBarcodeFormat().toString()); // Prints the scan format (qrcode)

        // show the scanner result into dialog box.
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setTitle("Scan Result");
        builder.setMessage(rawResult.getText());
        AlertDialog alert1 = builder.create();
        alert1.show();

  // If you would like to resume scanning, call this method below:
        // mScannerView.resumeCameraPreview(this);

    }}

试试这个，

在MainActivity.java添加

中

TextView scanResult = (TextView)findViewById(R.id.txtScanResult);

在handleResult

中

scanResult.setText(rawResult.getText().toString);

如何将结果存储在条形码的文本视图中？
