我有一个类，它将显示用户的出勤情况，但是我有一个问题，因为我存储在不同的数据库引用中。我如何调用数据库的两个子级，并根据到目前为止的出勤类型在回收者布局中显示某些信息，但我在下面有此内容，但是它不能正常工作。这里的数据库结构是Structure 活动代码为：
ref.addValueEventListener(new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
int size = (int) dataSnapshot.getChildrenCount();
tc.setText("PRESENT :" +size);
list = new ArrayList<>();
list1=new ArrayList<AttendenceList>();
// list2 = new ArrayList<>();
if(dataSnapshot.exists()) {
// StringBuffer stringbuffer = new StringBuffer();
for (DataSnapshot dataSnapshot1 : dataSnapshot.getChildren()) {
// Intent abintent=getIntent();
EmployeeInformation userdetails = dataSnapshot1.getValue(EmployeeInformation.class);
String naame = userdetails.getNaame();
String employeeno = userdetails.getEmployeeno();
String locationla = userdetails.getLocationla();
String locationlo = userdetails.getLocationlo();
String time = userdetails.getTime();
String report = userdetails.getReport();
String captureimage = userdetails.getCaptureImageUrl();
String totalMember = userdetails.getTeamMember();
String timeTaken = userdetails.getTimeCompletion();
String locationaddress = userdetails.getLocationName();
String membername = userdetails.getMemberName();
String locationimage = userdetails.getLocationPic();
String day=userdetails.getDay();
AttendenceList listdata = new AttendenceList(naame, locationla, locationlo, time, report, employeeno, captureimage, timeTaken, locationimage, totalMember, membername, locationaddress ,day);
list.add(listdata);
}
recycler = new FullAttendenceList(FullAttendenceDetailList.this, list,list2);
RecyclerView.LayoutManager layoutmanager = new LinearLayoutManager(FullAttendenceDetailList.this);
// (LinearLayoutManager) layoutmanager).setOrientation(RecyclerView.VERTICAL);
Precyclerview.setLayoutManager(layoutmanager);
Precyclerview.setItemAnimator(new DefaultItemAnimator());
Precyclerview.setAdapter(recycler);
recycler.notifyDataSetChanged();
pd.dismiss();
}else
{
pd.dismiss();
Toast.makeText(FullAttendenceDetailList.this, "No one mark their attendence 1", Toast.LENGTH_LONG).show();
}
}
@Override
public void onCancelled(DatabaseError error) {
// Failed to read value
startActivity(new Intent(FullAttendenceDetailList.this, NetworkSlow.class));
Toast.makeText(FullAttendenceDetailList.this, "Network problem check it", Toast.LENGTH_SHORT).show();
pd.dismiss();
// Log.w(TAG, "Failed to read value.", error.toException());
}
});
ref2.addValueEventListener(new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
int size = (int) dataSnapshot.getChildrenCount();
tc1.setText("ABSENT :" + size);
list2 = new ArrayList<>();
if (dataSnapshot.exists()) {
// StringBuffer stringbuffer = new StringBuffer();
for (DataSnapshot dataSnapshot1 : dataSnapshot.getChildren()) {
EmployeeInformation userdetails = dataSnapshot1.getValue(EmployeeInformation.class);
String naame = userdetails.getNaame();
String employeeno = userdetails.getEmployeeno();
String locationla = userdetails.getLocationla();
String locationlo = userdetails.getLocationlo();
String time = userdetails.getTime();
String report = userdetails.getReport();
String captureimage = userdetails.getCaptureImageUrl();
String totalMember ="-"; //userdetails.getTeamMember();
String timeTaken = "-";//userdetails.getTimeCompletion();
String locationaddress ="-";// userdetails.getLocationName();
String membername ="-";// userdetails.getMemberName();
String locationimage ="-";// userdetails.getLocationPic();
String day="-";//userdetails.getDay();
AttendenceList listdata2 = new AttendenceList(naame, locationla, locationlo, time, report, employeeno, captureimage, timeTaken, locationimage, totalMember, membername, locationaddress ,day);
list2.add(listdata2);
// list1.add(list,list2);
}
recycler = new FullAttendenceList(FullAttendenceDetailList.this,list ,list2);
RecyclerView.LayoutManager layoutmanager = new LinearLayoutManager(FullAttendenceDetailList.this);
//(LinearLayoutManager) layoutmanager).setOrientation(RecyclerView.VERTICAL);
Precyclerview.setLayoutManager(layoutmanager);
Precyclerview.setItemAnimator(new DefaultItemAnimator());

recycler.notifyDataSetChanged();
pd.dismiss();
}else
{
pd.dismiss();
Toast.makeText(FullAttendenceDetailList.this, "No one mark their attendence 2", Toast.LENGTH_LONG).show();
}
}
@Override
public void onCancelled(DatabaseError error) {
// Failed to read value

});
现在的适配器类代码为：
public class FullAttendenceList extends RecyclerView.Adapter<FullAttendenceList.MyHolder>{
List<AttendenceList> attendencelistdata;
List<AttendenceList> attendencelistdata2;
Context context;
public FullAttendenceList(Context context){
this.context = context;
}
public FullAttendenceList(Context context,List<AttendenceList> attendencelistdata ,List<AttendenceList> attendencelistdata2) {
this.context = context;
this.attendencelistdata = attendencelistdata;
this.attendencelistdata2 = attendencelistdata2;
}
@Override
public FullAttendenceList.MyHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.fullattendance_list, parent, false);
FullAttendenceList.MyHolder myHolder = new FullAttendenceList.MyHolder(view);
return myHolder;
}
public void onBindViewHolder(FullAttendenceList.MyHolder holder, int position) {
AttendenceList data = attendencelistdata.get(position);

holder.presentRelative.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {

if (!holder.vday.getText().equals("-")) {
Intent i = new Intent(context, PresentReportingActivity.class);

});
}
@Override
public int getItemCount() {
return (attendencelistdata2.size() );// attendencelistdata2.size();
}
它只显示一个缺席用户列表，但不显示当前用户。我希望它同时显示两个用户
