javascript - Android Studio Zxing Scanner，如果QR码的结果是URL，如何重定向到网页？

Question

这是我的代码我正在寻找有关使用 ZXing 扫描仪的 Android 应用程序的帮助。如果结果是 URL，我希望它重定向到一个网站。提前致谢。

以下是我的代码:

公共(public)类 MainActivity 扩展 AppCompatActivity {

private Button button;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    button = (Button) this.findViewById(R.id.button);
    final Activity activity = this;
    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            IntentIntegrator integrator = new IntentIntegrator(activity);
            integrator.setDesiredBarcodeFormats(IntentIntegrator.ALL_CODE_TYPES);
            integrator.setPrompt("Scan");
            integrator.setCameraId(0);
            integrator.setBeepEnabled(false);
            integrator.setBarcodeImageEnabled(false);
            integrator.initiateScan();
        }
    });
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
    if(result != null) {
        if(result.getContents() == null) {
            Log.d("MainActivity", "Cancelled scan");
            Toast.makeText(this, "Cancelled", Toast.LENGTH_LONG).show();
        } else {
            Log.d("MainActivity", "Scanned");
            Toast.makeText(this, "Scanned: " + result.getContents(), Toast.LENGTH_LONG).show();
        }
    } else {
        // This is important, otherwise the result will not be passed to the fragment
        super.onActivityResult(requestCode, resultCode, data);
        public void handleResult(Result result) {
            if(Patterns.WEB_URL.matcher(result.getText).matches()) {
                // Open URL
                Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(result.getText()));
                startActivity(browserIntent);
            }
        }

    }
}

这是要检查的条件:

if(android.util.Patterns.WEB_URL.matcher(result.getContents().trim()).matches() ||  result.getContents().trim().contains("www.")){

      // code to redirect to webview
      launchURL(result.getContents().trim())

}

要重定向到 webview:

1> 使用自定义标签

Add to your gradle

implementation 'com.android.support:customtabs:27.0.2'

Call this function to redirect

void launchURL(String url){
       CustomTabsIntent.Builder builder = new CustomTabsIntent.Builder();
       CustomTabsIntent customTabsIntent = builder.build();
       customTabsIntent.launchUrl(mContext, Uri.parse(url));
       builder.setToolbarColor(ContextCompat.getColor(mContext,R.color.colorPrimary));
   }

或

2>使用 Intent

if (!result.getContents().trim().contains("http")) {
      result.getContents().trim()= "http://" + url;
   }
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(result.getContents().trim()));
