这是我的MainActivity：

公共类MainActivity扩展了Activity {

TextView text;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    text = (TextView)findViewById(R.id.textView1);
    Button mQrcode = (Button)findViewById(R.id.button1);
    mQrcode.setOnClickListener(new OnClickListener() {

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