关于ListView的报错

错误例子：

public View getView(int position, View convertView, ViewGroup parent) {

People people = getItem(position);
View view;
if (convertView == null) {
view = LayoutInflater.from(getContext()).inflate(resourceId, null);
} else {
view = convertView;
}

TextView nameView = (TextView) view.findViewById(R.id.name_Id);
TextView ageView = (TextView) view.findViewById(R.id.age_Id);
nameView.setText(people.getName());
ageView.setText(people.getAge());
return view;

}

解决办法：

setText()方法只接受字符串型的数据，所以当要把一个int型数据输出时，需要转换成字符串型

ageView.setText(“” + people.getAge());
