java - 扫描仪中的 URL 结果

Question

我在编程方面还是个新手，我尝试为我的项目构建一个代码扫描器。问题是结果只显示文本。无法点击或直接进入浏览器。

public class ReaderActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_reader);
        Button scan_btn = findViewById(R.id.scan_btn);
        final Activity activity = this;

        IntentIntegrator qrScan = new IntentIntegrator(this);

        scan_btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                IntentIntegrator integrator = new IntentIntegrator(activity);
                integrator.setDesiredBarcodeFormats(IntentIntegrator.QR_CODE_TYPES);
                integrator.setPrompt("Scan");
                integrator.setCameraId(0);
                integrator.setBeepEnabled(false);
                integrator.setBarcodeImageEnabled(false);
                integrator.initiateScan();
                view.setOnClickListener(new View.OnClickListener() {

                    @Override
                    public void onClick(View v) {
                        // TODO Auto-generated method stub

                    }
                });

            }
        });
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
        if(result != null){
            if(result.getContents()==null){
                Toast.makeText(this, "You cancelled the scanning", Toast.LENGTH_LONG).show();
            }
            else {
                Toast.makeText(this, result.getContents(), Toast.LENGTH_LONG).show();
            }
        }
        else {
            super.onActivityResult(requestCode, resultCode, data);




        }


    }
}

有人能解决这个问题吗？

您可以检查result.getContents()是否以“http”或“https”开头，使用string.indexOf，获取它并放入您的浏览器。
