实现代码：

public class MyCodeActivity extends BaseActivity implements View.OnClickListener {

private TextView txt_title, txt_right, tvname, tv_accout;private ImageView img_back;

@Overridepublic void onCreate(Bundle savedInstanceState) {        setContentView(R.layout.activity_mycode);super.onCreate(savedInstanceState);    }

@Overridepublic void onClick(View v) {switch (v.getId()) {case R.id.img_back:                Utils.finish(MyCodeActivity.this);break;default:break;        }    }

@Overrideprotected void initControl() {txt_title = (TextView) findViewById(R.id.txt_title);txt_title.setText("我的二维码");img_back = (ImageView) findViewById(R.id.img_back);img_back.setVisibility(View.VISIBLE);tvname = (TextView) findViewById(R.id.tvname);tv_accout = (TextView) findViewById(R.id.tvmsg);    }

@Overrideprotected void initView() {img_back.setOnClickListener(this);    }

@Overrideprotected void initData() {        String id = Utils.getValue(this, Constants.User_ID);tv_accout.setText("微信号：" + id);        User user = GloableParams.Users.get(id);if (user != null && !TextUtils.isEmpty(user.getUserName()))tvname.setText(user.getUserName());        Bitmap qrcode = generateQRCode("[email protected]:" + id);        ImageView imageView = (ImageView) findViewById(R.id.img_code);        imageView.setImageBitmap(qrcode);    }

@Overrideprotected void setListener() {// TODO Auto-generated method stub}

private Bitmap generateQRCode(String content) {try {            QRCodeWriter writer = new QRCodeWriter();// MultiFormatWriter writer = new MultiFormatWriter();BitMatrix matrix = writer.encode(content, BarcodeFormat.QR_CODE, 500, 500);return bitMatrix2Bitmap(matrix);        } catch (WriterException e) {            e.printStackTrace();        }return null;    }

private Bitmap bitMatrix2Bitmap(BitMatrix matrix) {int w = matrix.getWidth();int h = matrix.getHeight();int[] rawData = new int[w * h];for (int i = 0; i < w; i++) {for (int j = 0; j < h; j++) {int color = Color.WHITE;if (matrix.get(i, j)) {                    color = Color.BLACK;                }                rawData[i + (j * w)] = color;            }        }

Bitmap bitmap = Bitmap.createBitmap(w, h, Bitmap.Config.RGB_565);        bitmap.setPixels(rawData, 0, w, 0, 0, w, h);return bitmap;    }}

生成二维码的函数generateQRCode可以重用，使用了zxing的QRCodeWriter。
