创建一个类Api:

public class Api {
     public  static  final  String banner="https://www.zhaoapi.cn/ad/getAd";
     public static final String syfenlei="https://www.zhaoapi.cn/product/getCatagory";
     public static final String ctouxiang="https://www.zhaoapi.cn/file/upload";
}

mainActivity

private static final int CHOOSE_PICTURE = 0;
private static final int TAKE_PICTURE = 1;
private static final int CROP_SMALL_PICTURE = 2;
private static Uri tempUri;

final AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
