Android 调用url以按文本字符串打开

好的，我正在制作一个应用程序，在结果上使用qr扫描仪，我有文本显示，带有代码的url，onclick侦听器中有没有办法调用结果中的文本并在浏览器中打开它？如果有，我该怎么做

    Button browser = (Button) findViewById(R.id.ulibutton);
        browser.setOnClickListener(new View.OnClickListener() {

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

                        getString(R.string.contents_text)));

                startActivity(i);

            }
        });

        ImageView barcodeImageView = (ImageView) findViewById(R.id.barcode_image_view);
        if (barcode == null) {
            barcodeImageView.setImageBitmap(BitmapFactory.decodeResource(
                    getResources(), R.drawable.icon));
        } else {
            barcodeImageView.setImageBitmap(barcode);
        }

        TextView formatTextView = (TextView) findViewById(R.id.format_text_view);

        DateFormat formatter = DateFormat.getDateTimeInstance(DateFormat.SHORT,
                DateFormat.SHORT);
        String formattedTime = formatter.format(new Date(rawResult
                .getTimestamp()));
        TextView timeTextView = (TextView) findViewById(R.id.time_text_view);
        timeTextView.setText(formattedTime);

        TextView metaTextView = (TextView) findViewById(R.id.meta_text_view);
        View metaTextViewLabel = findViewById(R.id.meta_text_view_label);
        metaTextView.setVisibility(View.GONE);

        Map<ResultMetadataType, Object> metadata = rawResult
                .getResultMetadata();

            for (Map.Entry<ResultMetadataType, Object> entry : metadata
                    .entrySet()) {
                if (DISPLAYABLE_METADATA_TYPES.contains(entry.getKey())) {
                    metadataText.append(entry.getValue()).append('\n');
                }
            }
            if (metadataText.length() > 0) {
                metadataText.setLength(metadataText.length() - 1);
                metaTextView.setText(metadataText);
                metaTextView.setVisibility(View.VISIBLE);
                metaTextViewLabel.setVisibility(View.VISIBLE);
            }
        }

        TextView contentsTextView = (TextView) findViewById(R.id.contents_text_view);
        contentsTextView.setMovementMethod(LinkMovementMethod.getInstance());
        CharSequence displayContents = resultHandler.getDisplayContents();
        contentsTextView.setText(displayContents);
        // Crudely scale betweeen 22 and 32 -- bigger font for shorter text
        int scaledSize = Math.max(22, 32 - displayContents.length() / 4);
        contentsTextView.setTextSize(TypedValue.COMPLEX_UNIT_SP, scaledSize);
    }
}

 Intent i = new Intent(Intent.ACTION_VIEW,Uri.parse(YourUrl)));
 startActivity(i);
