barcodescanner - 无法解析 resumeCameraPreview 方法

Question

我正在使用 barcodescanner 库。

"SimpleScannerActivity"有一个示例代码：

public class SimpleScannerActivity extends Activity implements ZXingScannerView.ResultHandler {
    private ZXingScannerView mScannerView;

    @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) {
        // Do something with the result here
        Log.v(TAG, rawResult.getText()); // Prints scan results
        Log.v(TAG, rawResult.getBarcodeFormat().toString()); // Prints the scan format (qrcode, pdf417 etc.)

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

我已经复制了 class 并且一切正常。但只有重新运行 onResume() 方法的方法不起作用，并出现以下错误消息：

mScannerView.resumeCameraPreview(这个); 无法解析方法‘resumeCameraPreview(com.ads.adstimer.fragment.Registration.Slides,FullScannerActivity)’

我真的不明白我做错了什么以及我该如何解决这个问题，因为我刚刚复制了该代码...

最终解决方案很简单：

从 1.8.3 更改依赖版本：

compile 'me.dm7.barcodescanner:zxing:1.8.3'

到 1.8.4:

compile 'me.dm7.barcodescanner:zxing:1.8.4'
