我在回收站视图中遇到处理多行布局的问题。我希望有4行不同的布局，这个适配器只显示2个布局，并没有显示下一个2.请帮我修复此问题。我在下面添加了适配器代码：
> package com.example.sikandar.recycler;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
import java.util.ArrayList;
import java.util.List;

private ArrayList<Datalist> dataList;
private static final int TYPE_holder1 = 1;
private static final int TYPE_OPTION_holder2 = 2;
private static final int TYPE_OPTION_holder3 = 3;
private static final int TYPE_OPTION_holder4 = 4;
// Provide a reference to the views for each data item
// Complex data items may need more than one view per item, and
// you provide access to all the views for a data item in a view holder
public static class ViewHolder extends RecyclerView.ViewHolder {
// each data item is just a string in this case
public View view;
public ViewHolder(View v) {
super(v);
view = v;
}
}
// Provide a suitable constructor (depends on the kind of dataset)
public MyAdapter(ArrayList<Datalist> dataList) {
this.dataList = dataList;
}

这是数据主义者
package com.example.sikandar.recycler;
/**

*/
class Datalist {
String email;
String Mobile;
String Phone;
String DegDur;
String Intake;
String enrollment;
String reg;
String classs;
String buemail;
String Padress;
String Cadress;
String FatherName;
String ComWork;
public Datalist(String DegDur,String Cadress,String Paddress,String enroll,String FatherName,String clas,String mobile,String email,String reg,String intake,String Comwork,String buemail){
this.DegDur=DegDur;
this.Intake=intake;
this.ComWork=Comwork;
this.buemail=buemail;
this.FatherName=FatherName;
this.enrollment=enroll;
this.Padress=Paddress;
this.Cadress=Cadress;
this.classs=clas;
this.Mobile=mobile;
this.email=email;
this.reg=reg;
}
public String getDegDur(){
return DegDur;
}
public String getIntake(){
return Intake;
}
public String getComWork(){
return ComWork;
}
public String getBuemail(){
return buemail;
}
public String getFatherName(){
return FatherName;
}
public String getEnrollment(){
return enrollment;
}
public String getPadress(){
return Padress;
}
public String getCadress(){
return Cadress;
}
public String getClasss(){
return classs;
}
public String getEmail(){
return email;
}
public String getMobile(){
return Mobile;
}
public String getPhone(){
return Phone;
}
public String getReg(){
return reg;
}
}
这是在datalist中添加项目的地方
recyclerView = (RecyclerView) findViewById(R.id.scrollableview);
recyclerView.setHasFixedSize(true);
LinearLayoutManager linearLayoutManager = new LinearLayoutManager(this);
recyclerView.setLayoutManager(linearLayoutManager);
email="Sikandar44iqbal@yahoo.com";

Phone="05178601";
DegDur="4 Years";

enrollment="01-134132-180";
reg="3375";
classs="BSCS 5B";
buemail="1234466465@bui.com";
Padress="Houe 03, main college road, F-7/3 Islamabad.";
Cadress="Houe 03, main college road, F-7/3 Islamabad.";
FatherName="Zafar Iqbal";
ComWork="Not Completed!";
ArrayList<Datalist> dataList = new ArrayList<Datalist>();
for (int i = 0; i < 2; i ++ ) {
dataList.add(new Datalist(DegDur,Cadress,Padress,enrollment,FatherName,classs,Mobile,email,reg,Intake,ComWork,buemail));
}
if (simpleRecyclerAdapter == null) {
simpleRecyclerAdapter = new MyAdapter(dataList);
recyclerView.setAdapter(simpleRecyclerAdapter);
}
