java自定义ArrayAdapter仅显示最后的信息
我有一个ArrayAdapter
它列出了用户的数据,但它列出了最后一个用户的数据,它显示了正确的行数,如果有5个用户,它显示了5行,但它们都是相同的,最后一个用户
主要活动是:
for(DataSnapshot Ds : dS.getChildren()) {
Object key = Ds.getKey();
String StringKey = String.valueOf(key);
getname(StringKey);
}
private void getname(String ID){
final String IDfinal = ID;
DatabaseReference.addValueEventListener(new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
Name = dataSnapshot.child("Users").child(IDfinal).child("name").getValue(String.class);
Email = dataSnapshot.child("Users").child(IDfinal).child("email").getValue(String.class);
Gender = dataSnapshot.child("Users").child(IDfinal).child("gender").getValue(String.class);
Birthday = dataSnapshot.child("Users").child(IDfinal).child("data_birth").getValue(String.class);
UserInformation ID = new UserInformation(Name,Email,Gender,Birthday);
userInformationsList.add(ID);
list();
Toast.makeText(SearchActivity.this,Name,Toast.LENGTH_SHORT).show();
}
@Override
public void onCancelled(DatabaseError databaseError) {
Toast.makeText(SearchActivity.this,"Error 404",Toast.LENGTH_SHORT).show();
}
});
}
private void list(){
customAdapter customAdapterIntent= new customAdapter(this,R.layout.userslist,userInformationsList);
mListView.setAdapter(customAdapterIntent);
}
}
用户信息。爪哇
public class UserInformation {
private static String Name;
private static String Gender;
private static String Email;
private static String Birthday;
public UserInformation(String Name,String Gender,String Email,String Birthday){
this.Birthday=Birthday;
this.Email=Email;
this.Gender=Gender;
this.Name=Name;
}
public static String getName(){return Name;}
public static String getEmail(){return Email;}
public static String getGender(){return Gender;}
public static String getBirthday(){return Birthday;}
}
自定义适配器。爪哇
public class customAdapter extends ArrayAdapter<UserInformation> {
public customAdapter(Context context, int layoutResource, List<UserInformation> userInformationsList) {
super(context, layoutResource, userInformationsList);
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = convertView;
if (view == null) {
LayoutInflater layoutInflater = LayoutInflater.from(getContext());
view = layoutInflater.inflate(R.layout.userslist, null);
}
UserInformation userInformation = getItem(position);
if (userInformation != null) {
TextView Name = (TextView) view.findViewById(R.id.textNameList);
//name.setText(name[position]);
TextView email = (TextView) view.findViewById(R.id.textEmailList);
//email.setText(Email[position]);
TextView gender = (TextView) view.findViewById(R.id.textGenderList);
//gender.setText(Gender[position]);
TextView birthday = (TextView) view.findViewById(R.id.textBirthdayList);
//birthday.setText(Birthday[position]);
if (Name != null) {
Name.setText(UserInformation.getName());
}
if (email != null) {
email.setText(UserInformation.getEmail());
}
if (gender != null) {
gender.setText(UserInformation.getGender());
}
if (birthday != null) {
birthday.setText(UserInformation.getBirthday());
}
}
return view;
}
}
# 1 楼答案
要设置值,为什么要使用类(UserInformation)而不是类名,请使用其对象UserInformation
还有一件事,使下面的值非静态
