项目工作正常但我的问题是如何从QR码阅读器导航到特定URL。什么是导航的代码请任何人告诉我并帮助我。 AndroidBarcodeQrExample.java

public class AndroidBarcodeQrExample extends Activity {

    static final String ACTION_SCAN = "com.google.zxing.client.android.SCAN";
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
    public void scanQR(View v) {
        try {
            Intent intent = new Intent(ACTION_SCAN);
            intent.putExtra("SCAN_MODE", "QR_CODE_MODE");
            startActivityForResult(intent, 0);
        } catch (Exception e) {

        }
    }
    public void onActivityResult(int requestCode, int resultCode, Intent intent) {
        if (requestCode == 0) {
            if (resultCode == RESULT_OK) {
                String contents = intent.getStringExtra("SCAN_RESULT");
                String format = intent.getStringExtra("SCAN_RESULT_FORMAT");

                Toast toast = Toast.makeText(this, "Content:" + contents + " Format:" + format, Toast.LENGTH_LONG);
                toast.show();
            }
        }
    }
}

<?xml version="1.0" encoding="utf-8"?>
