我是Android网络新手。我无法弄清楚为什么我为 phonone
获得空值这是JSON数据的示例:
{
"columns":{ <some data here> },
"rows":[
{
"timestamp":"28/08/2016 14:11:46",
"name":"Mohammed Sohail",
"phoneno.":8142629002,
"event-name":"Roadies",
"branch":"IT",
"year":3
},
{
"timestamp":"28/08/2016 14:13:03",
"name":"Shaik Asaduddin",
"phoneno.":8143026049,
"event-name":"Ted talk",
"branch":"IT",
"year":3
}
}
我能够获得行数组中的每个值,除了“phoneno”它给我的空值
这是我的课程
注册课程:
public class Registration {
private Columns columns;
private List<Row> rows = null;
private Map<String, Object> additionalProperties = new HashMap<String, Object>();
public Columns getColumns() {
return columns;
}
public void setColumns(Columns columns) {
this.columns = columns;
}
public List<Row> getRows() {
return rows;
}
public void setRows(List<Row> rows) {
this.rows = rows;
}
public Map<String, Object> getAdditionalProperties() {
return this.additionalProperties;
}
public void setAdditionalProperty(String name, Object value) {
this.additionalProperties.put(name, value);
}
}
行类:
public class Row {
private String timestamp;
private String name;
private String phoneno;
private String eventName;
private String branch;
private String year;
public String getTimestamp() {
return timestamp;
}
public void setTimestamp(String timestamp) {
this.timestamp = timestamp;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPhoneno() {
return phoneno;
}
public void setPhoneno(String phoneno) {
this.phoneno = phoneno;
}
public String getEventName() {
return eventName;
}
public void setEventName(String eventName) {
this.eventName = eventName;
}
public String getBranch() {
return branch;
}
public void setBranch(String branch) {
this.branch = branch;
}
public String getYear() {
return year;
}
public void setYear(String year) {
this.year = year;
}
}
这是我用来设置文本视图的
的适配器public class RegistrationAdapter extends RecyclerView.Adapter<RegistrationAdapter.RegistrationViewHolder> {
private List<Row> rows;
private Context context;
private int rowLayout;
public RegistrationAdapter(List<Row> rows) {
this.rows=rows;
}
@Override
public RegistrationAdapter.RegistrationViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.registration_item_view, parent, false);
return new RegistrationViewHolder(view);
}
@Override
public void onBindViewHolder(RegistrationViewHolder holder, int position) {
holder.studentName.setText(rows.get(position).getName());
holder.studentPhone.setText(String.valueOf(rows.get(position).getPhoneno()));
holder.studentBranch.setText(rows.get(position).getBranch());
holder.studentYear.setText(rows.get(position).getYear());
}
@Override
public int getItemCount() {
return rows.size();
}
public class RegistrationViewHolder extends RecyclerView.ViewHolder {
LinearLayout studentLayout;
TextView studentName;
TextView studentPhone;
TextView studentBranch;
TextView studentYear;
public RegistrationViewHolder(View itemView) {
super(itemView);
studentLayout=(LinearLayout)itemView.findViewById(R.id.studentLayout);
studentName=(TextView)itemView.findViewById(R.id.studentName);
studentPhone=(TextView)itemView.findViewById(R.id.studentPhoneNumber);
studentBranch=(TextView)itemView.findViewById(R.id.studentBranch);
studentYear=(TextView)itemView.findViewById(R.id.studentYear);
}
}
public RegistrationAdapter( List<Row> rows, int rowLayout,Context context) {
this.rows = rows;
this.rowLayout = rowLayout;
this.context = context;
}
}
答案 0 :(得分:1)
也许是一个错字,但在你的json中,你有&#34; phoneno。&#34;你的行类指定了phoneno。

你可以使用jsonschema2pojo从json对象中生成类。
