TextView nameTxt,emailTxt, usernameTxt;
ImageView dataImg;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_detail);

    Button btn_shear =(Button) findViewById(R.id.shear);
    dataImg = (ImageView) findViewById(R.id.iv_preview_image);
