onActivityResult 通过case对不同情况进行处理

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    switch (resultCode) {
        case 10:
            Toast.makeText(getActivity(),"haha",Toast.LENGTH_SHORT);
            Bundle a = data.getExtras();
            String url = a.getString("picture");
            String alterusername = a.getString("username");
            Bitmap bm = BitmapFactory.decodeFile(url);
            avatarImg.setImageBitmap(bm);
            UserNameTextView.setText(alterusername);
            break;
        case 1:
            Bundle b = data.getExtras();
            String index = b.getString("servicepointname");
            UserFuWuTextView.setText(index);//设置服务范围的显示TextView
            break;
        case 20:
            Bundle c = data.getExtras();
            String username = c.getString("UserName");
            String userphone = c.getString("UserPhone");
            UserPhoneTextView.setText(userphone);
            UserNameTextView.setText(username);
            break;
    }

    super.onActivityResult(requestCode, resultCode, data);
}
