我隔离了我的错误，它似乎来自该行:
mJours.add(new Jour((String.valueOf(cn.get_id()) + " Mars 2016"), cn.get_minimum(), cn.get_maximum()));
我的Java类
Jour的代码是: public class Jour {
private int mTempMin;
private int mTempMax;
private String mDates;
public Jour(String date, int min, int max) {
mTempMin = min;
mTempMax = max;
mDates = date;
}
public String getmDates() {
return mDates;
}
public void setmDates(String mDates) {
this.mDates = mDates;
}
public int getmTempMin() {
return mTempMin;
}
public void setmTempMin(int mTempMin) {
this.mTempMin = mTempMin;
}
public int getmTempMax() {
return mTempMax;
}
public void setmTempMax(int mTempMax) {
this.mTempMax = mTempMax;
}
}
谢谢，
希望我们能找到答案!

public View getView(int position, View convertView, ViewGroup parent) {
View theView = convertView;
if (theView == null) {
theView = mInflater.inflate(R.layout.jour_list_item, parent, false);
}
// Le hero
Jour jour = this.getItem(position);
// Aller chercher les objets
TextView lblMin = (TextView) theView.findViewById(R.id.lblMin);
TextView lblMax = (TextView) theView.findViewById(R.id.lblMax);
TextView lblDate = (TextView) theView.findViewById(R.id.lblDate);
// Assigner les valeurs
lblMin.setText(jour.getmTempMin());
lblMax.setText(jour.getmTempMax());
lblDate.setText(jour.getmDates());
// Retourner la vue
return theView;
}
@Override
public View getDropDownView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
return getView(position, convertView, parent);
}
}
最佳答案
lblMin.setText(jour.getmTempMin());
lblMax.setText(jour.getmTempMax());
您正在调用需要资源ID的
setText(int)。要改为使用setText(CharSequence)，您可以将代码更改为例如lblMin.setText(String.valueOf(jour.getmTempMin()));
lblMax.setText(String.valueOf(jour.getmTempMax()));
