更新、以下を参照してください。
クラス LocationData と ArrayList listOfObjects を onPostExecute() に返すにはどうすればよいですか? UI で使用したいのですが、現在は AsyncTask のバックグラウンドにあります。また、マーカーを追加したい：
mMap.addMarker(new MarkerOptions()
.position(new LatLng(lati, longi))
.title(name));
各ループの後に新しい場所をそれぞれマップに追加できるようにします。
LocationData クラスを返した後、上記を onPostExecute に配置しますか?
try {
String apples = endpoint.listContactInfo().execute().toString();
JSONObject jObject = new JSONObject(apples);
JSONArray jsonArr = jObject.getJSONArray("items");
for (int i = 0; i < jsonArr.length(); i++) {
JSONObject jsonObj1 = jsonArr.getJSONObject(i);
// Storing each json item in variable
String id = jsonObj1.getString(TAG_ID);
String nameFirst1 = jsonObj1.getString(TAG_FIRSTNAME);
String nameLast1 = jsonObj1.getString(TAG_LASTNAME);
String emailAddress1 = jsonObj1.getString(TAG_EMAIL);
String streetAddress1 = jsonObj1.getString(TAG_ADDRESS);
String phone1 = jsonObj1.getString(TAG_PHONE);
// test to see if made it to string
Log.d("YOUR_TAG", "First Name: " + nameFirst1 + " Last Name: "
+ nameLast1);
address = coder.getFromLocationName(streetAddress1, 5);
Address location1 = address.get(0);
// SET LAT LNG VALUES FOR MARKER POINT
lati = location1.getLatitude();
longi = location1.getLongitude();
Log.d("Location", "Location:" + lati + " " + longi);
class LocationData {
private double lat;
private double longitude;
private String name;
public LocationData(double lat, double longitude,
String name) {
this.lat = lat;
this.longitude = longitude;
this.name = name;
}
public void setLat(double lat) {
this.lat = lat;
}
public void setLongitude(double longitude) {
this.longitude = longitude;
}
public double getLat() {
return lat;
}
public double getLongitude() {
return longitude;
}
public void setName(String name) {
this.name = name;
}
public String getName() {
return name;
}
}
ArrayList<LocationData> listOfObjects = new ArrayList<LocationData>();
listOfObjects.add(new LocationData(lati, longi, nameFirst1));
}
} catch (IOException e) {
e.printStackTrace();
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return (long) 0;
}
// WHAT DO I PUT HERE TO RETURN LocationData Class here
// ADD MARKER TO MAP UI
protected void onPostExecute() {
// mMap.addMarker(new MarkerOptions()

これは基本的なことのように思えるかもしれませんが、私はこのメソッドを作成しました: public ArrayList getLocationData() {
ArrayList<LocationData> listOfObjects = new ArrayList<LocationData>();
listOfObjects.add(new LocationData(lati, longi, nameFirst1));
return listOfObjects;
}
私の LocationData クラス内。次に、LocationData.getLocationData(); を配置しました。onPostExecute を使用すると、LocationData を解決できません。現時点では、コードをまとめると次のようになります。
try {
String apples = endpoint.listContactInfo().execute().toString();
JSONObject jObject = new JSONObject(apples);
JSONArray jsonArr = jObject.getJSONArray("items");
for(int i =0 ; i<jsonArr.length() ;i++ ){
JSONObject jsonObj1 = jsonArr.getJSONObject(i);
// Storing each json item in variable
String id = jsonObj1.getString(TAG_ID);
final String nameFirst1 = jsonObj1.getString(TAG_FIRSTNAME);
String nameLast1 = jsonObj1.getString(TAG_LASTNAME);
String emailAddress1 = jsonObj1.getString(TAG_EMAIL);
String streetAddress1 = jsonObj1.getString(TAG_ADDRESS);
String phone1 = jsonObj1.getString(TAG_PHONE);
//test to see if made it to string
Log.d("YOUR_TAG", "First Name: " + nameFirst1 + " Last Name: " + nameLast1);
address = coder.getFromLocationName(streetAddress1,5);
Address location1 = address.get(0);
// SET LAT LNG VALUES FOR MARKER POINT
lati = location1.getLatitude();
longi = location1.getLongitude();
Log.d("Location", "Location:" + lati + " " + longi);
class LocationData {
private double lat;
private double longitude;
private String name;
public LocationData(double lat, double longitude, String name) {
this.lat = lat;
this.longitude = longitude;
this.name = name;
}
public void setLat(double lat) {
this.lat = lat;
}
public void setLongitude(double longitude) {
this.longitude = longitude;
}
public double getLat() {
return lat;
}
public double getLongitude() {
return longitude;
}
public void setName(String name) {
this.name = name;
}
public String getName() {
return name;
}
public ArrayList<LocationData> getLocationData() {
ArrayList<LocationData> listOfObjects = new ArrayList<LocationData>();
listOfObjects.add(new LocationData(lati, longi, nameFirst1));
return listOfObjects;
}
}
}
} catch (IOException e) {
e.printStackTrace();
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return (long) 0;
}
//WHAT DO I PUT HERE TO RETURN LocationData Class here
// ADD MARKER TO MAP UI
protected void onPostExecute(Long result ) {
//CANT BE RESOLVED
LocationData.getLocationData();
//mMap.addMarker(new MarkerOptions()
//.position(new LatLng(lati, longi))

@Sustain の推奨事項に基づく私の変更は次のとおりです。現在、マップマーカーを取得していないようです。何か見た人いますか？
