此博客展示了一段Android项目代码，包含包导入、类定义等内容。代码涉及RecyclerView、CheckBox、TextView等控件，还引入了适配器和Presenter，用于实现商品列表展示等功能，属于Android开发范畴。

package movie.bw.com.week2moni;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;
import android.view.View;
import android.widget.CheckBox;
import android.widget.CompoundButton;
import android.widget.TextView;

public class MainActivity extends BaseActivity {
@BindView(R.id.recycle)
RecyclerView recycle;
MyAdapter myAdapter;
private CheckBox checkall;
private TextView price;
private ShopPersenter shopPersenter;

@Override
protected void initView(Bundle savedInstanceState) {
    checkall = findViewById(R.id.checkall);
    price = findViewById(R.id.price);
    shopPersenter = new ShopPersenter(new ShopCall());
    shopPersenter.requestData("159","1557736557381159");
    myAdapter = new MyAdapter(this);
    recycle.setAdapter(this.myAdapter);


    LinearLayoutManager manager = new LinearLayoutManager(this);
    manager.setOrientation(LinearLayoutManager.VERTICAL);
    recycle.setLayoutManager(manager);

    myAdapter.setPriceListener(new MyAdapter.PriceListener() {
        @Override
        public void priceListener(double sum) {
            price.setText(sum+"");
        }
    });
    checkall.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
            List<Goods> goodslist = myAdapter.getList();
            for (int i=0;i<goodslist.size();i++){
                Goods goods = goodslist.get(i);
                goods.check=isChecked;
            }
            myAdapter.calculatePrice();
            myAdapter.notifyDataSetChanged();
        }
    });
}

@Override
protected int getLayoutId() {
    return R.layout.activity_main;
}
class ShopCall implements DataCall<List<Goods>> {

    @Override
    public void success(List<Goods> data, Object... args) {
            myAdapter.addAll(data);
            myAdapter.calculatePrice();
            myAdapter.notifyDataSetChanged();
    }

    @Override
    public void fail(Result data, Object... args) {

    }
}

@Override
protected void onDestroy() {
    super.onDestroy();
    shopPersenter.doStory();
}
