Android_实现商品详情的展示页及布局
okhttp封装及logge拦截器:
http://blog.csdn.net/qq_40087961/article/details/78828811
,,记得要导入依赖及权限
商品详情页的model层
public class RecyclerDetailsModel {
//自己定义的方法
public void receive(String pid, final IRecyclerDetailsModel iRecyclerDetailsModel) {
String url="http://120.27.23.105/product/getProductDetail";
HashMap<String, String> hashMap = new HashMap<>();
hashMap.put("pid", pid);
OkHttpUtils.getInstance().doPost(url, hashMap, new CallBack() {
@Override
public void onSuccess(String str) {
if (str != null) {
Gson gson = new Gson();
RecyclerDetailsBean rdBean = gson.fromJson(str, RecyclerDetailsBean.class);
if (rdBean != null) {
iRecyclerDetailsModel.onSuccess(rdBean);
}
}
}
@Override
public void onFailed(String message) {
iRecyclerDetailsModel.onFailed();
}
});
}
} |
商品详情页的model层的借口
public interface IRecyclerDetailsModel {
void onSuccess(RecyclerDetailsBean rdBean);
void onFailed();
} |
商品详情页的view层接口
public interface IRecyclerDetailsPresenter {
void onSuccess(RecyclerDetailsBean rdBean);
void onFailed();
} |
商品详情页的presenter层
public class RecyclerDetailsPresenter implements IRecyclerDetailsModel {
private RecyclerDetailsModel recyclerDetailsModel;
private IRecyclerDetailsPresenter irecyclerDetailsPresenter;
public RecyclerDetailsPresenter(IRecyclerDetailsPresenter irecyclerDetailsPresenter) {
this.irecyclerDetailsPresenter = irecyclerDetailsPresenter;
recyclerDetailsModel = new RecyclerDetailsModel();
}
public void receive(String pid) {
recyclerDetailsModel.receive(pid, this);
}
@Override
public void onSuccess(RecyclerDetailsBean rdBean) {
irecyclerDetailsPresenter.onSuccess(rdBean);
}
@Override
public void onFailed() {
irecyclerDetailsPresenter.onFailed();
}
} |
主要的view层
public class RecyclerDetailsActivity extends AppCompatActivity implements IRecyclerDetailsPresenter,IAddShopCarPresenter{
private int pid = 71;
private RecyclerDetailsPresenter recyclerDetailsPresenter;
private ListView listView;
private RecyclerDetailsBean.DataBean data;
private TextView title;
private TextView price;
private String urlImg;
private String[] split;
private String urlTitle;
private double urlPrice;
private ArrayList<String> lists = new ArrayList<String>();
private ViewPager viewPager;
private DetailsAdapter adapter;
private Button join;
private int pids;
private AddShopCarPresenter addShopCarPresenter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_details);
initview();
//Intent intent = getIntent();
//pid = intent.getIntExtra("pid", this.pid);
//获取商品详情页的p层
recyclerDetailsPresenter = new RecyclerDetailsPresenter(this);
//调用商品详情页的获取pid的方法
recyclerDetailsPresenter.receive(pid + "");
//将商品添加到购物车的p层
addShopCarPresenter = new AddShopCarPresenter(this);
}
/**
* 获取控件的方法
*
* */
private void initview() {
//轮播展示图片的控件
viewPager = (ViewPager) findViewById(R.id.viewPager);
//点击加入购物车的控件
join = (Button) findViewById(R.id.join);
title = (TextView) findViewById(R.id.title);
price = (TextView) findViewById(R.id.price);
}
/*
* 实现成功的方法
* */
@Override
public void onSuccess(RecyclerDetailsBean rdBean) {
/**
* 从集合获取数据,并赋值
*/
data = rdBean.getData();
pids = data.getPid();
urlImg = data.getImages();
split = urlImg.split("\\|");
urlTitle = data.getTitle();
urlPrice = data.getPrice();
title.setText(urlTitle);
price.setText(urlPrice + "");
/**
* 将图片做成无限轮播
* 配置适配器
*/
adapter = new DetailsAdapter(RecyclerDetailsActivity.this, split);
viewPager.setAdapter(adapter);
/**
* 点击加入购物车的按钮
*/
join.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
/*Toast.makeText(RecyclerDetailsActivity.this, ImageLoaderApp.sql.getInt("id", 0)+"", Toast.LENGTH_SHORT).show();*/
//传入加入购物车的字段
addShopCarPresenter.receive("android", 3381+"", pids + "");
}
});
}
@Override
public void onSuccess(String msg) {
Toast.makeText(RecyclerDetailsActivity.this, msg, Toast.LENGTH_SHORT).show();
}
@Override
public void onFailed() {
}
/**
* 跳转购物车
* @param view
*/
public void shopcar(View view){
Intent intent = new Intent(RecyclerDetailsActivity.this, ShoppingCartActivity.class);
startActivity(intent);
}
} |
图片轮播适配器
/**
* 详情页的图片的无限轮播
*/
public class DetailsAdapter extends PagerAdapter {
private Context context;
private String[] split;
public DetailsAdapter(Context context, String[] split) {
this.context = context;
this.split = split;
}
@Override
public int getCount() {
return Integer.MAX_VALUE;
}
@Override
public Object instantiateItem(ViewGroup container, int position) {
//添加图片到布局中
View view = View.inflate(context, R.layout.layout_detailviewpager, null);
ImageView img = view.findViewById(R.id.img);
Glide.with(context).load(split).into(img);
container.addView(view);
return view;
}
@Override
public void destroyItem(ViewGroup container, int position, Object object) {
container.removeView((View) object);
}
@Override
public boolean isViewFromObject(View view, Object object) {
return view==object;
}
} |
RecyclerDetailsActivity 的xml布局
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v4.view.ViewPager
android:id="@+id/viewPager"
android:layout_width="match_parent"
android:layout_height="250dp"></android.support.v4.view.ViewPager>
<TextView
android:id="@+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@id/viewPager"
android:text="标题"
android:textSize="22sp" />
<TextView
android:id="@+id/price"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@id/title"
android:text="价格"
android:textColor="#F00"
android:textSize="22sp" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_alignParentBottom="true"
>
<Button
android:id="@+id/shopcar"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="50dp"
android:text="购物车"
android:onClick="shopcar"
/>
<Button
android:id="@+id/join"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="50dp"
android:text="加入购物车" />
</LinearLayout>
</RelativeLayout> |
适配器的布局
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="@+id/img"
android:scaleType="fitXY"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout> |
