View:主要负责界面的显示及跟数据无关的逻辑,比如设置控件的点击事件等
Presenter:主要负责View与Model的交互
Model:数据部分
-------
MVP的核心是:
View层不持有Model层对象任何引用,当然参数里面和临时变量里可以有Model层对象,只持有Presenter层对象引用,任何需要更新或者操作数据的,都间接通过Presenter对象去操作数据。而Model层想要操作View层是无法实现的,必须通过Presenter层。
Presenter层持有View层对象的引用,除此之外不持有其他的UI控件等的引用,Model层会把想要更新View的操作委托Presenter去操作,而Presenter层会把更新View操作交给View层对象去操作。
-------
1、view 层,实现:
public class GoodsActivity extends Activity implements ViewPager.OnPageChangeListener, OnPageClickListener, ShoppingMarkContentView {
2、ShoppingMarkContentView :
package com.wbh.mall.views.iviews; import com.wbh.mall.restful.bean.GoodDTO; import com.wbh.mall.restful.bean.UserDataListDTO; import java.util.List; public abstract interface ShoppingMarkContentView { public abstract void refershRecommendItemList(List<GoodDTO> paramList); public abstract void refreshCollectSameMarkUserInfo(UserDataListDTO paramUserDataListDTO); public abstract void refreshItemDetail(GoodDTO paramGoodDTO); public abstract void setFollow(short paramShort); }
3、在GoodsActivity 中实现上面的方法:
@Override
@SuppressLint({"MissingSuperCall"})
protected void onResume() {
super.onResume();
this.markContentPresenter.start();
}
@Override
public void refershRecommendItemList(List<GoodDTO> paramList) {
runOnUiThread(new Runnable() {
@Override
public void run() {
if ((paramList != null) && (!paramList.isEmpty())) {
GoodsActivity.this.recommend_good_container.setVisibility(0);
GoodsActivity.this.recommendGoodListAdapter.goodDTOS.addAll(paramList);
GoodsActivity.this.recommend_good_list_recyclerview.notifyFinish();
}
}
});
}
其实在他上面有个入口:
@Override public void onCreate(Bundle savedInstanceState) { this.markContentPresenter.tuijianGoods(false);
public void tuijianGoods(boolean b) { if (!b) { this.manager.current_page = 1; this.lastUpDate = DateUtil.getCurrentTime(); } int j = this.manager.page_num; int i = this.manager.current_page; long l = this.lastUpDate; String str = this.articleId; if (TextUtils.isEmpty(this.itemUrl) == true) { } StringBuilder sb = new StringBuilder(); sb.append(this.num_iid); sb.append(""); markSource.tuiJianGoods(j, i, l, str, sb.toString()); }
在 public class ShoppingMarkContentPresenter extends Presenter {中定义上面的方法;
4、请求服务器:
public class MarkRestSource extends RestSource {
public void tuiJianGoods(int paramInt1, int paramInt2, long paramLong, String paramString1, String paramString2) { Map localMap = createPhoneInfoMap(); localMap.put("pageSize", Integer.valueOf(paramInt1)); localMap.put("pageNo", Integer.valueOf(paramInt2)); localMap.put("lastUpDate", Long.valueOf(paramLong)); if (!TextUtils.isEmpty(paramString1)) { localMap.put("articleId", paramString1); } if (!TextUtils.isEmpty(paramString2)) { localMap.put("num_iid", paramString2); } cleanNullParams(localMap); this.markApi.tuiJianGoods(localMap).enqueue(new Callback() { @Override public void onResponse(Call call, Response response) { int i = response.code(); if (i == 200) { MarkRestSource.this.storeToken(((MarkRestResponse.TuijianGoodsResponse) response.body()).token); MarkRestSource.this.dataBus.post(response.body()); } else { MarkRestSource.this.dataBus.post(new MarkRestResponse.TuijianGoodsResponse(Integer.valueOf(i))); } } @Override public void onFailure(Call call, Throwable throwable) { MarkRestSource.this.dataBus.post(new MarkRestResponse.TuijianGoodsResponse(Integer.valueOf(2000))); } }); }
