自定义view订单评价星星

自定义view订单评价星星

最近自定义了评价星星的view,可以直接xml上更改各种属性（评价的类型，评价的星星数量，默认评价的数量）

先看一下效果图：

当设置评价的类型为3种类型，名称为：描述相符，物流服务，服务态度；每种评价的星星数量为5；默认为1颗星

 当设置评价的类型为4种类型，名称为：描述相符，物流服务，服务态度，产品质量；每种评价的星星数量为3；默认为3颗星

实现的原理是：把每一行评价，包括评价类型，评价星星看作是listview中的一个item,每个item中的星星又看作一个小的listview,

下面把代码贴出来：

1. StartSetView:自定义view

public class StartSetView extends LinearLayout {int typs=3;//多少级List<String> names=new ArrayList<String>();//每一级的名称（质量/综合/物流等等）int start_num=5;//每级多少星星int default_num=3;//默认多少星List<StartTypeBean> list=new ArrayList<StartTypeBean>();RecyclerView startTypeLv;StartTypeAdapter typeAdapter;Context context;public StartSetView(Context context,int typs,List<String> names,int start_num,int default_num) {super(context);initView( context,null);ps=typs;this.names=names;this.start_num=start_num;this.default_num=default_t=context;initData();
}public StartSetView(Context context, @Nullable AttributeSet attrs) {super(context, attrs);t=context;initView( context,attrs);initData();}public StartSetView(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {super(context, attrs, defStyleAttr);t=context;initView( context,attrs);initData();}public StartSetView(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {super(context, attrs, defStyleAttr, defStyleRes);t=context;initView( context,attrs);initData();}void initView(Context context,AttributeSet attrs){LayoutInflater.from(context).inflate(R.layout.start_set_view, this, true);startTypeLv=this.findViewById(R.id.start_type_lv);if(attrs!=null) {TypedArray ta = context.obtainStyledAttributes(attrs, R.styleable.startview);typs = ta.getInteger(R.styleable.startview_types, 3);start_num = ta.getInteger(R.styleable.startview_start_num, 5);default_num = ta.getInteger(R.styleable.startview_default_num, 3);String namestr&#String(R.styleable.startview_names);Log.d("Test","types"+typs);Log.d("Test","start_num"+start_num);Log.d("Test","default_num"+default_num);Log.d("Test","namestr"+namestr);if(namestr!=null&&!namestr.equals("")){String[] strs=namestr.split(",");for(int i=0;i<strs.length;i++){names.add(strs[i]);}}ta.recycle();}}void initData(){if(names.size()==0){names.add("质量") ;names.add("综合");names.add("物流");}for(int i=0;i<typs;i++){StartTypeBean startTypeBean=new StartTypeBean();if(i<names.size()) {startTypeBean.(i));}List<StartBean> startBeans=new ArrayList<StartBean>();for(int j=0;j<start_num;j++){StartBean bean=new StartBean();if(j<default_num){bean.setChoose(true);}startBeans.add(bean);}startTypeBean.setStarts(startBeans);list.add(startTypeBean);}if(list!=null&&list.size()>0){typeAdapter=new StartTypeAdapter(context,list);LinearLayoutManager manager=new LinearLayoutManager(context);startTypeLv.setLayoutManager(manager);startTypeLv.setAdapter(typeAdapter);}}}

2.自定义view 布局R.layout.start_set_view

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android=""android:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical">
&lerview.widget.RecyclerViewandroid:layout_width="match_parent"android:layout_height="wrap_content"android:id="@+id/start_type_lv"/>
</LinearLayout>

3.自定义view里面会涉及到两个adapter,外层的和内层的：

3.1：StartTypeAdapter

public class StartTypeAdapter extends RecyclerView.Adapter<StartTypeAdapter.ViewHolder> {Context context;LayoutInflater inflater;List<StartTypeBean> list;public StartTypeAdapter(Context context, List<StartTypeBean> list) {t = context;this.list = list;this.inflater = LayoutInflater.from(context);}@NonNull@Overridepublic ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {View view = inflater.inflate(R.layout.start_type_item_layout, parent, false);ViewHolder viewHolder = new ViewHolder(view);return viewHolder;}@Overridepublic void onBindViewHolder(@NonNull ViewHolder holder, int position) {StartTypeBean bean&#(position);String name&#Name();if(name!=null){holder.nameTv.setText(name);}Starts()!=null){StartAdapter startAdapter=new StartAdapter(Starts());LinearLayoutManager manager=new LinearLayoutManager(context,RecyclerView.HORIZONTAL,false);holder.startsRv.setLayoutManager(manager);holder.startsRv.setAdapter(startAdapter);}}@Overridepublic int getItemCount() {return list.size();}class ViewHolder extends RecyclerView.ViewHolder {@BindView(R.id.starts_rv)RecyclerView startsRv;@BindView(R.id.name_tv)TextView nameTv;public ViewHolder(@NonNull View itemView) {super(itemView);ButterKnife.bind(this,itemView);}}}

布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android=""android:layout_width="match_parent"android:layout_height="match_parent"android:orientation="horizontal"android:padding="10dp"><TextViewandroid:layout_width="wrap_content"android:layout_height="wrap_content"android:text="质量"android:id="@+id/name_tv"/>&lerview.widget.RecyclerViewandroid:layout_width="match_parent"android:layout_height="wrap_content"android:id="@+id/starts_rv"android:layout_marginLeft="10dp"/>
</LinearLayout>

3.2 StartAdapter

public class StartAdapter extends RecyclerView.Adapter<StartAdapter.ViewHolder> {Context context;LayoutInflater inflater;List<StartBean> list;public StartAdapter(Context context, List<StartBean> list) {t = context;this.list = list;this.inflater = LayoutInflater.from(context);}@NonNull@Overridepublic ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {View view = inflater.inflate(R.layout.start_item_layout, parent, false);ViewHolder viewHolder = new ViewHolder(view);return viewHolder;}@Overridepublic void onBindViewHolder(@NonNull ViewHolder holder, int position) {StartBean bean&#(position);if(bean.isChoose()){holder.ivIcon.setImageResource(R.mipmap.pj);//选择的时候亮星星的图片}else{holder.ivIcon.setImageResource(R.mipmap.pj_n);//不选择的时候星星灰色的图片}}@Overridepublic int getItemCount() {return list.size();}class ViewHolder extends RecyclerView.ViewHolder {@BindView(R.id.iv_icon)ImageView ivIcon;public ViewHolder(@NonNull View itemView) {super(itemView);ButterKnife.bind(this, itemView);}}
}

布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android=""android:layout_width="wrap_content"android:layout_height="wrap_content"android:orientation="vertical"android:padding="2.5dp">
<ImageViewandroid:layout_width="15dp"android:layout_height="15dp"android:src="@mipmap/pj"android:id="@+id/iv_icon"/>
</LinearLayout>

4.其中的自定义属性文件&#l

<?xml version="1.0" encoding="utf-8"?>
<resources><declare-styleable name="startview"><attr name="types" format="integer" /><attr name="start_num" format="integer" /><attr name="default_num" format="integer" /><attr name="names" format="string" /></declare-styleable></resources>

5.activity引用：

5.1布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android=""xmlns:tools=""android:layout_width="match_parent"android:layout_height="match_parent"xmlns:app=""android:orientation="vertical">
&stdemoactivity.view.StartSetViewandroid:layout_width="match_parent"android:layout_height="wrap_content"android:id="@+id/start"app:types="4"app:start_num="3"app:default_num="3"app:names="描述相符,物流服务,服务态度,产品质量"/>
</LinearLayout>

5.2:activity:暂时没有添加其他点击的事件，自定义view中也还没有添加

public class StartCommentActivity extends AppCompatActivity {@Overrideprotected void onCreate(@Nullable Bundle savedInstanceState) {Create(savedInstanceState);setContentView(R.layout.start_comment_activity);}
}
