按ISBN搜索图书

Question

我是 Google Books API的新手，我尝试了很多来自 Stackoverflow 和 Youtube 的教程。

我想从多个 API 中搜索 ISBN 的书籍，但我无法弄清楚如何做到这一点。我实施了条形码扫描仪，但我不知道如何将其与 Google Books API 或 Goodreads API

一起使用

这是我获取 ISBN 的地方：

public class ScanFragment extends Fragment {

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

    new IntentIntegrator(this.getActivity());
    IntentIntegrator integrator = IntentIntegrator.forSupportFragment(this);
    // use forSupportFragment or forFragment method to use fragments instead of activity
    integrator.setDesiredBarcodeFormats(IntentIntegrator.ONE_D_CODE_TYPES);
    integrator.setPrompt(this.getString(R.string.scan_bar_code));
    integrator.setResultDisplayDuration(0); // milliseconds to display result on screen after scan
    integrator.setCameraId(0);  // Use a specific camera of the device
    integrator.initiateScan();
}

/**
 * function handle scan result
 * @param requestCode scanned code
 * @param resultCode  result of scanned code
 * @param intent intent
 */
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
    //retrieve scan result
    IntentResult scanningResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, intent);
    ScanResultReceiver parentActivity = (ScanResultReceiver) this.getActivity();

    if (scanningResult != null) {
        //we have a result
        String codeContent = scanningResult.getContents();
        String codeFormat = scanningResult.getFormatName();
        // send received data
        parentActivity.scanResultData(codeFormat, codeContent);

    }else{
        // send exception
        String noResultErrorMsg = "No scan data received!";
        parentActivity.scanResultData(new NoScanResultException(noResultErrorMsg));
    }
}
}

就是这样，因为我不知道如何从多个品牌实施 API'S 。 请帮帮我!!
