Question

我正在尝试在我的微调器上添加json对象但是按照我的方式给出了正确的结果我跟随https://inducesmile.com/android/populate-android-spinner-data-from-remote-mysql-database/please的tutoreal建议我。

input: "ABC"|"CDS"|""gurgaon""|"ABC"|"CDS"|""gaon""

Output: "ABC"|"CDS"|"/"gurgaon"|"ABC"|"CDS"|"/"gaon

}

@SerializedName("Status")
@Expose
private String status;
@SerializedName("ExpiryDate")
@Expose
private String expiryDate;
@SerializedName("MessagesLeft")
@Expose
private String messagesLeft;
@SerializedName("Users")
@Expose
private List<User> users = null;
@SerializedName("Balance")
@Expose
private String balance;

public String getStatus() {
    return status;
}

public void setStatus(String status) {
    this.status = status;
}

public String getExpiryDate() {
    return expiryDate;
}

public void setExpiryDate(String expiryDate) {
    this.expiryDate = expiryDate;
}

public String getMessagesLeft() {
    return messagesLeft;
}

public void setMessagesLeft(String messagesLeft) {
    this.messagesLeft = messagesLeft;
}

public List<User> getUsers() {
    return users;
}

public void setUsers(List<User> users) {
    this.users = users;
}

public String getBalance() {
    return balance;
}

public void setBalance(String balance) {
    this.balance = balance;
}

导入com.google.gson.annotations.SerializedName;

公共类用户{

import com.google.gson.annotations.Expose;

} 和Adpater Class就是这样。

@SerializedName("username")
@Expose
private String username;

@SerializedName("userid")
@Expose
private String userid;

public String getUsername() {
    return username;
}

public void setUsername(String username) {
    this.username = username;
}

public String getUserid() {
    return userid;
}

public void setUserid(String userid) {
    this.userid = userid;
}

}

Answer 1

您正尝试将列表设置为textview，这是不可能的，请尝试按照代码设置文本

spinnerHolder.spinnerItemList.setText(listData.get(position).getUsers().get(0).getUsername());

Answer 2

您正在尝试将列表数据设置为TextView视图。而不是尝试此状态，其中position将是您要显示的用户位置

spinnerHolder.spinnerItemList.setText(listData.get(position).getUsers().get(position).getUsername());

错误：（51,39）TextView类型中的方法setText（CharSequence）不适用于参数（List <user>）
