左边栏的adapter

}

右边栏的adapter

}

左边传值时用的接口

package likuo.bwie.com.fenlei.persenter;/*** date:2018/11/22* author:李阔(淡意衬优柔)* function:*/
public interface onClicklistener {void cid(String cid);
}

右边传值用的接口

package likuo.bwie.com.fenlei.persenter;/*** date:2018/11/22* author:李阔(淡意衬优柔)* function:*/
public interface onsssCliclinstener {void pscid(String pscid);
}

SecondActivity就是只显示了传的值

package likuo.bwie.com.fenlei;import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.widget.TextView;public class SecondActivity extends AppCompatActivity {private TextView text11;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_second);initView();Intent intent = getIntent();String ppp = intent.getStringExtra("ppp");text11.setText(ppp);}private void initView() {text11 = (TextView) findViewById(R.id.text11);}
}

main的布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:app="http://schemas.android.com/apk/res-auto"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"tools:context=".MainActivity"android:orientation="horizontal"><android.support.v7.widget.RecyclerViewandroid:layout_width="0dp"android:layout_weight="2"android:layout_height="match_parent"android:id="@+id/recyclerview"/><ScrollViewandroid:layout_width="0dp"android:layout_weight="5"android:layout_height="match_parent"android:id="@+id/scrollView"><LinearLayoutandroid:layout_width="match_parent"android:layout_height="match_parent"android:id="@+id/linear"android:orientation="vertical"></LinearLayout></ScrollView>
</LinearLayout>

左边需要的子条目的布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:orientation="vertical" android:layout_width="match_parent"android:layout_height="match_parent"><TextViewandroid:layout_width="wrap_content"android:layout_height="wrap_content"android:id="@+id/textview"android:textSize="35sp"/>
</LinearLayout>

右边条目的布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:orientation="vertical"android:layout_width="wrap_content"android:layout_height="wrap_content"><ImageViewandroid:layout_width="80dp"android:layout_height="80dp"android:id="@+id/image"/><TextViewandroid:layout_width="wrap_content"android:layout_height="wrap_content"android:id="@+id/textview1"/>
</LinearLayout>

second的布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:app="http://schemas.android.com/apk/res-auto"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"tools:context=".SecondActivity"><TextViewandroid:layout_width="wrap_content"android:layout_height="wrap_content"android:id="@+id/text11"android:textSize="80sp"/></LinearLayout>

person是左半边的

package likuo.bwie.com.fenlei.bean;import java.util.List;/*** date:2018/11/22* author:李阔(淡意衬优柔)* function:*/
public class Person {private String msg;private String code;private List<DataBean> data;public String getMsg() {return msg;}public void setMsg(String msg) {this.msg = msg;}public String getCode() {return code;}public void setCode(String code) {this.code = code;}public List<DataBean> getData() {return data;}public void setData(List<DataBean> data) {this.data = data;}public static class DataBean {private int cid;private String createtime;private String icon;private int ishome;private String name;public int getCid() {return cid;}public void setCid(int cid) {this.cid = cid;}public String getCreatetime() {return createtime;}public void setCreatetime(String createtime) {this.createtime = createtime;}public String getIcon() {return icon;}public void setIcon(String icon) {this.icon = icon;}public int getIshome() {return ishome;}public void setIshome(int ishome) {this.ishome = ishome;}public String getName() {return name;}public void setName(String name) {this.name = name;}}
}

bean是右边的

public class Beans {private String msg;private String code;private List<DataBean> data;public String getMsg() {return msg;}public void setMsg(String msg) {this.msg = msg;}public String getCode() {return code;}public void setCode(String code) {this.code = code;}public List<DataBean> getData() {return data;}public void setData(List<DataBean> data) {this.data = data;}public static class DataBean {private String cid;private String name;private String pcid;private List<ListBean> list;public String getCid() {return cid;}public void setCid(String cid) {this.cid = cid;}public String getName() {return name;}public void setName(String name) {this.name = name;}public String getPcid() {return pcid;}public void setPcid(String pcid) {this.pcid = pcid;}public List<ListBean> getList() {return list;}public void setList(List<ListBean> list) {this.list = list;}public static class ListBean {/*** icon : http://120.27.23.105/images/icon.png* name : 月饼* pcid : 1* pscid : 1*/private String icon;private String name;private int pcid;private int pscid;public String getIcon() {return icon;}public void setIcon(String icon) {this.icon = icon;}public String getName() {return name;}public void setName(String name) {this.name = name;}public int getPcid() {return pcid;}public void setPcid(int pcid) {this.pcid = pcid;}public int getPscid() {return pscid;}public void setPscid(int pscid) {this.pscid = pscid;}}}
