Presenter 類

//獲取特惠內容：

UI層的fragment
public class OnSaleFragment extends BaseFragment implements IOnSalePageCallback {
@BindView(R.id.on_sale_list)
public RecyclerView onSaleList;
public OnSalePageAdapter onSalePageAdapter;
public OnSalePagePresenter onSalePagePresenter;
@Override
protected void initPresenter() {
super.initPresenter();
/**
這里是有個PresenterManager類里面回傳各個fragment中presenter的單例
*/
onSalePagePresenter = PresenterManager.getInstance().getOnSalePagePresenter();
onSalePagePresenter.registerViewCallback(this);
onSalePagePresenter.getContent();
}
@Override
protected int getRootVireResId() {
/**
*/
Log.d("OnSaleFragment", "fragment_red_packet is created" );
return R.layout.fragment_red_packet;
}
@Override
protected void initView(View rootView) {
setUpState(State.SUCCESS);
onSalePageAdapter = new OnSalePageAdapter();
GridLayoutManager gridLayoutManager = new GridLayoutManager(getContext(),2);
onSaleList.setLayoutManager(gridLayoutManager);
onSaleList.setAdapter(onSalePageAdapter);
}
@Override
public void onContentLoadSuccess(OnSaleContent content) {
//資料回來：
Log.d("OnSaleFragment", "OnSaleContent" + content );
onSalePageAdapter.setData(content);
}
@Override
public void onMoreloaded(OnSaleContent content) {
}
@Override
public void onMoreLoadError() {
}
@Override
public void onMoreLoadEmpty() {
}
@Override
public void onNetworkError() {
}
@Override
public void onLoading() {
}
@Override
public void onEmpty() {
}
}
這邊跟著b站做專案。前面幾個fragment都是照著這么寫的，但是不知道這個為什么我這邊在Presenter類里面的log都打不出來。里面的 int code本來是我用來確認是否連接成功的，結果現在啥也看不到。后續UI那邊設定adapter也不成功是肯定的。請問會有可能是介面改變了所以我這邊什么都沒有嗎？因為怕太長所以沒有全部貼出來，如果有大佬需要看的，我在后面貼出來。謝謝大家。
