    //设置图片框架
    GenericDraweeHierarchy build=GenericDraweeHierarchyBuilder.newInstance(context.getResources())
            .setRoundingParams(RoundingParams.asCircle())
            .build();

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    recyclerView=findViewById(R.id.rec);
    present = new Present(this);
    present.getDataPresent("高跟鞋",page,count);
    GridLayoutManager gridLayoutManager=new GridLayoutManager(this,2);
    recyclerView.setLayoutManager(gridLayoutManager);
    cricleView=findViewById(R.id.cricle);
    //自定义框架点击搜素功能
    cricleView.setListener(new CricleView.onListener() {
        @Override
        public void getListener(String x) {
            present.getDataPresent(x,page,count);
        }
    });
    xBanner=findViewById(R.id.banner);
    Present present1 = new Present(this);
    present1.getBannerPresent();
}
//加载数据
@Override
public void getDataView(List<DataBean.ResultBean> dataBean) {
    DataAdapter dataAdapter = new DataAdapter(MainActivity.this, dataBean);
    recyclerView.setAdapter(dataAdapter);
}

@Override
public void getDetailsView(DetailsBean detailsBean) {

}
//加载banner
@Override
public void getBannerView(final List<BannerBean.ResultBean> list) {
    runOnUiThread(new Runnable() {
        @Override
        public void run() {
            xBanner.setData(list,null);
            xBanner.loadImage(new XBanner.XBannerAdapter() {
                @Override
                public void loadBanner(XBanner banner, Object model, View view, int position) {
                    Glide.with(MainActivity.this)
                            .load(list.get(position).getImageUrl())
                            .into((ImageView) view);
