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)));
}
});
}
BUS 事件传递
/**
* 订阅事件 EventBus @Subscribe
*
* @return Result<Xxxx>
*/
@Subscribe
public void tuijianGoodsResponse(MarkRestResponse.TuijianGoodsResponse paramTuijianGoodsResponse)
{
try
{
if ((paramTuijianGoodsResponse.code == 200) && (paramTuijianGoodsResponse.data != null)
&& paramTuijianGoodsResponse.data.list != null)
{
this.lastUpDate = paramTuijianGoodsResponse.data.lastUpDate;
PageManager localPageManager = this.manager;
boolean isLastPage;
if (paramTuijianGoodsResponse.data.isLastPage == 0) {
isLastPage = false;
} else {
isLastPage = true;
}
localPageManager.isLastPage = isLastPage;
this.markContentView.refershRecommendItemList(paramTuijianGoodsResponse.data.list);
if (TextUtils.isEmpty(this.itemUrl)) {
storeMarkrRecords(paramTuijianGoodsResponse.data.list);
}
}
else
{
this.markContentView.refershRecommendItemList(null);
}
}
catch (Exception ex)
{
ex.printStackTrace();
