如何解决在公共LocationResult之外访问字符串信息
| 我有如下脚本，从LocationResult获取网址以在httppost中使用public class List extends ListActivity {
int ct_id;
String[] ct_number = null;
String[] ct_address = null;
String[] ct_phone = null;
String[] ct_fax = null;
String[] ct_email = null;
String[] ct_city = null;
String[] ct_province = null;
String[] ct_country = null;
String[] ct_pcode = null;
String[] ct_lat = null;
String[] ct_long = null;
String[] ct_distance = null;
String[] ct_show = null;
String[] ct_listinfo = null;

解决方法
我的建议是尝试使用公共字符串...希望能有所帮助。
, 在上一个问题之后：
public LocationResult locationResult = new LocationResult() {
String latitude = null;
String longitude = null;
public void gotLocation(Location location) {
if (location != null) {
latitude = location.getLatitude() + \"\";
longitude = location.getLongitude() + \"\";
}
}
public String getLatitude() {
return latitude;
}
public String getLongitude() {
return longitude;
}
}
String location = new String (locationResult.getLatitude() + \" \" + locationResult.getLongitude());
gotLocation
public void postURL (String urlString) {
if (urlString == null) return;
HttpPost httppost = new HttpPost(urlString);
// whatever else code you have to handle responses,etc.
}
gotLocation()
TimsList.this.postURL (\"http://mytimmies.myfunhouse.net/app_main_list.php?lat=\" +
location.getLatitude() + \"&long=\" + location.getLongitude());
