一、lib下的MVP层
M:model接口
package com.example.lib.model;
public interface IModel {
//销毁
void distroy();
}
M:BaseModel类
package com.example.lib.model;
public class BaseModel implements IModel {
@Override
public void distroy() {
}
}
P:presenter接口
package com.example.lib.presenter;
public interface IPresenter {
void distroy();//销毁
}
P:BasePresenter类
package com.example.lib.presenter;
import com.example.lib.model.IModel;
import com.example.lib.view.IView;
public class BasePresenter<M extends IModel,V extends IView> implements IPresenter {
protected M mModel;
protected V mView;
public BasePresenter(M mModel, V mView) {
this.mModel = mModel;
this.mView = mView;
}
@Override
public void distroy() {
}
}
V:view接口
package com.example.lib.view;
public interface IView {
void showToast();//输出数据
}
V:Activity接口
package com.example.lib.view;
public interface IActivity {
int bindLayout();//绑定
void initView();//初始化组件
void initData();//初始化数据
}
V:Fragment接口
package com.example.lib.view;
public interface IFragment extends IActivity {
}
V:BaseFragment类
package com.example.lib.view;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import androidx.annotation.IdRes;
import androidx.annotation.NonNull;
import androidx.annotation.Nullable;
import androidx.fragment.app.Fragment;
import com.example.lib.presenter.IPresenter;
public abstract class BaseFragment<P extends IPresenter> extends Fragment implements IFragment {
protected P mPresenter;
protected View inflate;
public BaseFragment(P mPresenter, View inflate) {
this.mPresenter = mPresenter;
this.inflate = inflate;
}
protected BaseFragment() {
}
@Nullable
@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
inflate = inflater.inflate(bindLayout(), null);
return inflate;
}
@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
initView();
initData();
}
public View findViewById(@IdRes int id) {
return inflate.findViewById(id);
}
}
V:BaseActivity类
package com.example.lib.view;
import android.os.Bundle;
import androidx.annotation.Nullable;
import androidx.appcompat.app.AppCompatActivity;
import com.example.lib.presenter.IPresenter;
public abstract class BaseActivity<P extends IPresenter> extends AppCompatActivity implements IActivity,IView {
protected P mPresenter;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(bindLayout());
initView();
initData();
}
}
二、app实现项目
contract
package com.example.app2.mvp.contract;
import com.example.app2.entity.Food;
import com.example.lib.model.IModel;
import com.example.lib.view.IView;
import retrofit2.Callback;
public interface FoodContract {
interface FoodModel extends IModel{
void getData(Callback<Food> callback,int num);
}
interface FoodView extends IView{
void show(Food food);
}
}
M:model
package com.example.app2.mvp.model;
import com.example.app2.entity.Food;
import com.example.app2.mvp.api.App;
import com.example.app2.mvp.contract.FoodContract;
import retrofit2.Call;
import retrofit2.Callback;
import retrofit2.Retrofit;
import retrofit2.adapter.rxjava2.RxJava2CallAdapterFactory;
import retrofit2.converter.gson.GsonConverterFactory;
public class FoodModel implements FoodContract.FoodModel {
@Override
public void distroy() {
}
@Override
public void getData(Callback callback,int num) {
Retrofit retrofit = new Retrofit.Builder()
.baseUrl("http://www.qubaobei.com/")
.addConverterFactory(GsonConverterFactory.create())
.addCallAdapterFactory(RxJava2CallAdapterFactory.create())
.build();
App app = retrofit.create(App.class);
Call<Food> call = app.getCall();
call.enqueue(callback);
}
}
P:presenter
package com.example.app2.mvp.presenter;
import com.example.app2.entity.Food;
import com.example.app2.mvp.contract.FoodContract;
import com.example.lib.presenter.BasePresenter;
import retrofit2.Call;
import retrofit2.Callback;
import retrofit2.Response;
public class FoodPresenter extends BasePresenter<FoodContract.FoodModel,FoodContract.FoodView> {
public FoodPresenter(FoodContract.FoodModel mModel, FoodContract.FoodView mView) {
super(mModel, mView);
}
public void show(int num) {
mModel.getData(new Callback<Food>() {
@Override
public void onResponse(Call<Food> call, Response<Food> response) {
Food food1 = response.body();
mView.show(food1);
}
@Override
public void onFailure(Call<Food> call, Throwable t) {
}
},num);
}
}
万能适配器
package com.example.app2.adapter;
import android.widget.ImageView;
import androidx.annotation.Nullable;
import com.bumptech.glide.Glide;
import com.chad.library.adapter.base.BaseQuickAdapter;
import com.chad.library.adapter.base.BaseViewHolder;
import com.example.app2.R;
import com.example.app2.entity.Food;
import java.util.List;
public class FoodAdapter extends BaseQuickAdapter<Food.DataBean, BaseViewHolder> {
//大虾串适配器
public FoodAdapter(int layoutResId, @Nullable List<Food.DataBean> data) {
super(layoutResId, data);
}
@Override
protected void convert(BaseViewHolder helper, Food.DataBean item) {
helper.setText(R.id.tv,item.getTitle());
Glide.with(mContext).load(item.getPic()).into((ImageView) helper.getView(R.id.iv));
}
}
实现类
package com.example.app2.fragment;
import android.os.Bundle;
import androidx.annotation.NonNull;
import androidx.fragment.app.Fragment;
import androidx.recyclerview.widget.LinearLayoutManager;
import androidx.recyclerview.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Toast;
import com.example.app2.MainActivity;
import com.example.app2.R;
import com.example.app2.adapter.FoodAdapter;
import com.example.app2.entity.Food;
import com.example.app2.mvp.contract.FoodContract;
import com.example.app2.mvp.model.FoodModel;
import com.example.app2.mvp.presenter.FoodPresenter;
import com.example.lib.view.BaseFragment;
import com.google.gson.Gson;
import com.scwang.smartrefresh.layout.SmartRefreshLayout;
import com.scwang.smartrefresh.layout.api.RefreshLayout;
import com.scwang.smartrefresh.layout.listener.OnRefreshLoadMoreListener;
import java.util.ArrayList;
import java.util.List;
/**
* A simple {@link Fragment} subclass.
*/
public class OneFragment extends BaseFragment<FoodPresenter> implements FoodContract.FoodView {
private SmartRefreshLayout sm;
private RecyclerView rv;
private int num=1;
private FoodPresenter foodPresenter;
private List<Food.DataBean> list=new ArrayList<>();
private FoodAdapter foodAdapter;
public OneFragment(FoodPresenter mPresenter, View inflate) {
super(mPresenter, inflate);
}
public OneFragment() {
// Required empty public constructor
}
@Override
public int bindLayout() {
return R.layout.fragment_one;
}
@Override
public void initView() {
sm = (SmartRefreshLayout) findViewById(R.id.sm);
rv = (RecyclerView) findViewById(R.id.rv);
}
@Override
public void initData() {
foodPresenter = new FoodPresenter(new FoodModel(), this);
foodPresenter.show(1);
// mPresenter.show(1);
}
@Override
public void show(Food food) {
// Toast.makeText(getActivity(), ""+food.toString(), Toast.LENGTH_SHORT).show();
list.addAll(food.getData());
foodAdapter = new FoodAdapter(R.layout.item, list);
rv.setAdapter(foodAdapter);
rv.setLayoutManager(new LinearLayoutManager(getActivity()));
foodAdapter.notifyDataSetChanged();
sm.setOnRefreshLoadMoreListener(new OnRefreshLoadMoreListener() {
@Override
public void onl oadMore(@NonNull RefreshLayout refreshLayout) {
num++;
Toast.makeText(getActivity(), ""+num, Toast.LENGTH_SHORT).show();
foodAdapter.notifyDataSetChanged();
sm.finishLoadMore();
foodPresenter.show(num);
}
@Override
public void onRefresh(@NonNull RefreshLayout refreshLayout) {
list.clear();
num=1;
Toast.makeText(getActivity(), ""+num, Toast.LENGTH_SHORT).show();
foodAdapter.notifyDataSetChanged();
sm.finishRefresh();
foodPresenter.show(num);
}
});
}
@Override
public void showToast() {
}
}
