自定义搜索以及RecyclerView展示列表

这个是自定义布局完之后搜索展示数据我用的是MVP框架

自定义搜索布局

 <?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    >
   <LinearLayout
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
       android:orientation="horizontal"
       >
       <ImageView
           android:layout_width="50dp"
           android:layout_height="50dp"
           android:src="@drawable/aaa"
           android:id="@+id/mIV"
           />
       <EditText
           android:layout_width="wrap_content"
           android:layout_height="50dp"
           android:layout_weight="15"
           android:hint="请输入您要搜索的内容"
           android:id="@+id/mET"
           />
       <TextView
           android:layout_width="wrap_content"
           android:layout_height="wrap_content"
           android:text="搜索"
           android:textSize="25dp"
           android:id="@+id/mTV"
           />
   </LinearLayout>
<LinearLayout>

自己创建一个类在里面继承LinearLayout

public class SeekTitle extends LinearLayout {

private TextView mTV;
private EditText mET;
private ImageView mIV;


public SeekTitle(Context context) {
    super(context);
}

public SeekTitle(final Context context, AttributeSet attrs) {
    super(context, attrs);
    LayoutInflater.from(context).inflate(R.layout.seek,this);
     mIV = findViewById(R.id.mIV);
     mTV = findViewById(R.id.mTV);
     mET = findViewById(R.id.mET);

      mTV.setOnClickListener(new OnClickListener() {
         @Override
         public void onClick(View v) {
             String s = mET.getText().toString();
             if (s.isEmpty())
             {
                 Toast.makeText(context,"请输入内容",Toast.LENGTH_SHORT).show();
             }else
             {
                 onSeekClickLisenter.mSeek(s);
             }
         }
     });
}

public SeekTitle(Context context,  AttributeSet attrs, int defStyleAttr) {
    super(context, attrs, defStyleAttr);
}
//接口回调
public interface onSeekClickLisenter
{
    void mSeek(String text);
}
//声明接口
public onSeekClickLisenter onSeekClickLisenter;

public void setOnSeekClickLisenter(SeekTitle.onSeekClickLisenter onSeekClickLisenter) {
    this.onSeekClickLisenter = onSeekClickLisenter;
}

然后在Activity布局里面调用你自定定义的那个类这个是我自己定义的类

 <?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent"
    android:layout_height="match_parent">
    <weekone.com.bw.twoweekexam.title.SeekTitle
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/sk"
        ></weekone.com.bw.twoweekexam.title.SeekTitle>
</android.support.constraint.ConstraintLayout>

然后接下来你在你的主布局里面写你自己定义的控件的那个id就行然后就可以在你的Activity里面写展示数据了我用的是RecyclerView展示因为RecyclerView包括三种布局所以要写一下布局管理器

 rlv = view.findViewById(R.id.rlv);
 //布局管理器
LinearLayoutManager  layoutManager=new LinearLayoutManager(getActivity());
rlv.setLayoutManager(layoutManager);
   //实例化presnenter
presenter = new ShowPresenter();

这个是我刚写的自定义搜索 就是写这个监听就是把你写的presnenter传参写这个里面 把你自定义搜索接口回调里面你定义的那个参数传到presnenter里面

sk.setOnSeekClickLisenter(new SeekTitle.onSeekClickLisenter() {
    @Override
    public void mSeek(String text) {
        pa=text;
        presenter.show(pa,page);
    }
});

然后传到presenter层里面在里面定义model层把你自定义搜索的那个值在传给model

 public class ShowPresenter {

    private final ShowModel model;
    private final ShowView showView;

    //在构造方法中实例化model和view
    public ShowPresenter) {
        model = new ShowModel();
  
    }

    public void show(String text, int page) {
        model.showData(text,page);
     }
}

然后在model层里写网络请求我把网络请求写在外面了自己创建了一个utils
这个里面我写了单例模式和拦截器

 public class ShowUtils {
	    //单例模式
	    public  static ShowUtils showUtils;
	
	    private ShowUtils() {
	    }
	
	    public static ShowUtils getInstance()
	    {
	        if (showUtils==null)
	        {
	            //同步锁
	            synchronized (ShowUtils.class)
	            {
	                if (showUtils==null)
	                {
	                    showUtils=new ShowUtils();
	                }
	            }
	        }
	        return showUtils;
	    }
	    //doGet
	    public  void doGet(String url,String ss,int page, Callback callback)
	    {
	        //拦截器
	        HttpLoggingInterceptor httpLoggingInterceptor=new HttpLoggingInterceptor(new HttpLoggingInterceptor.Logger() {
	            @Override
	            public void log(String message) {
	                Log.i("xxx",message);
	            }
	        });
	        httpLoggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
	
	        //创建OkHttpClient
	        OkHttpClient okHttpClient=new OkHttpClient.Builder()
	                .addInterceptor(httpLoggingInterceptor)
	                .build();
	        Request request=new Request.Builder()
	                .url(url+"?keyword="+ss+"&page="+page+"&count=10")
	                .build();
	        Call call = okHttpClient.newCall(request);
	        call.enqueue(callback);
	    }

然后写完回到model层调用utils里面写的网络请求解析我用的是Gson解析

public class ShowModel {
   String url="http://172.17.8.100/small/commodity/v1/findCommodityByKeyword";
   //接口回调
    public interface onShowClickLisenter
   {
       void onResult( ArrayList<Result> results);
   }
   //声明接口
    private  onShowClickLisenter onShowClickLisenter;

    public void setOnShowClickLisenter(ShowModel.onShowClickLisenter onShowClickLisenter) {
        this.onShowClickLisenter = onShowClickLisenter;
    }

    private Handler handler=new Handler()
   {
       @Override
       public void handleMessage(Message msg) {
           super.handleMessage(msg);
           switch (msg.what)
           {
               case 0:
                   String obj = (String) msg.obj;
                   Gson gson = new Gson();
                   JsonBean jsonBean = gson.fromJson(obj, JsonBean.class);
                   ArrayList<Result> results=jsonB ean.getResult();
                    onShowClickLisenter.onResult(results);
                   break;
           }
       }
   };
    public void showData(String text, int page) {
      //创建网络请求
        ShowUtils.getInstance().doGet(url, text,page, new Callback() {
            @Override
            public void onFailure(Call call, IOException e) {

            }

            @Override
            public void onResponse(Call call, Response response) throws IOException {
                String s = response.body().string();
                Log.i("xxx",s);

                Message message = new Message();
                message.what=0;
                message.obj=s;
                //发送消息
                handler.sendMessage(message);
            }
        });
    }
}

因为解析写了接口回调需要在回调到presenter层把数据传给view层

public class ShowPresenter {

    private final ShowModel model;
    private final ShowView showView;

    //在构造方法中实例化model和view
    public ShowPresenter(ShowView view) {
        model = new ShowModel();
        showView = view;
    }

    public void show(String text, int page) {
        model.showData(text,page);
        model.setOnShowClickLisenter(new ShowModel.onShowClickLisenter() {
            @Override
            public void onResult(ArrayList<Result> results) {
                showView.view(results);
            }
        });
    }
}

然后在你Activity里面继承View层他会报错然后你ALT+回车就会出来一个方法
然后在里面写适配器
public class ShowFragment extends Fragment implements ShowView
{
public void view(ArrayList results) {

//适配器
final MyAdapter adapter=new MyAdapter(results,getActivity());
rlv.setAdapter(adapter);
}
}

适配器我写的是多条目

public class MyAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
   ArrayList<Result> results;
   Context context;
   public static int TYPE_ONE=0;
    public static int TYPE_TWO=1;

    public MyAdapter(ArrayList<Result> results, Context context) {
        this.results = results;
        this.context = context;
    }

    @Override
    public int getItemViewType(int position) {
        if (position%2==0)
        {
            return TYPE_ONE;
        }else
        {
            return TYPE_TWO;
        }
    }

    @NonNull
    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {
       if (i==TYPE_ONE)
       {
           View view = LayoutInflater.from(context).inflate(R.layout.item1, null, false);

           final MyViewHolder myViewHolder=new MyViewHolder(view); 
          return myViewHolder;
       }else
       {
           View view1= LayoutInflater.from(context).inflate(R.layout.item2, null, false);

           final MyViewHolder1 myViewHolder1=new MyViewHolder1(view1);
            return myViewHolder1;
       }
    }

    @Override
    public void onBindViewHolder(@NonNull RecyclerView.ViewHolder viewHolder, int i) {
        int type = getItemViewType(i);
        if (type==TYPE_ONE)
        {
            MyViewHolder myViewHolder= (MyViewHolder) viewHolder;
            myViewHolder.text1.setText(results.get(i).getCommodityId());
            myViewHolder.text2.setText(results.get(i).getCommodityName());
        }else
        {
            MyViewHolder1 myViewHolder1= (MyViewHolder1) viewHolder;
            myViewHolder1.item2_text.setText(results.get(i).getCommodityId());
            myViewHolder1.item2_text2.setText(results.get(i).getCommodityName());
            Glide.with(context).load(results.get(i).getMasterPic()).into(myViewHolder1.item2_image);
        }
    }

    @Override
    public int getItemCount() {
        return results.size();
    }
public  class MyViewHolder extends RecyclerView.ViewHolder
    {

        private final TextView text2;
        private final TextView text1;

        public MyViewHolder(@NonNull View itemView) {
            super(itemView);
            text1 = itemView.findViewById(R.id.text1);
            text2 = itemView.findViewById(R.id.text2);
        }
    }
    public  class MyViewHolder1 extends RecyclerView.ViewHolder
    {

        private final TextView item2_text;
        private final TextView item2_text2;
        private final ImageView item2_image;

        public MyViewHolder1(@NonNull View itemView) {
            super(itemView);
            item2_text = itemView.findViewById(R.id.item2_text);
            item2_text2 = itemView.findViewById(R.id.item2_text2);
            item2_image = itemView.findViewById(R.id.item2_image);
        }
    }
