Ich habe ein Problem mit diesem Code, kann Methode getMap() nicht lösen. Ich nicht finden, wo das Problem ist, bitte Hilfe mit Code, ich benutze Android Studio und Marker zu nehmen Standorte von mySQL mit Json.Android, Methode kann nicht aufgelöst werden getMap()
googleMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.googleMap)).getMap();`
Und hier ist voll Code
public class MainActivity extends FragmentActivity {
private GoogleMap googleMap;
private Double Latitude = 0.00;
private Double Longitude = 0.00;
private GoogleApiClient client2;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (Build.VERSION.SDK_INT > 9) {
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
}
ArrayList<HashMap<String, String>> location = null;
String url = "http://www.evil.cl/getLatLon.php";
try {
JSONArray data = new JSONArray(getHttpGet(url));
location = new ArrayList<HashMap<String, String>>();
HashMap<String, String> map;
for (int i = 0; i < data.length(); i++) {
JSONObject c = data.getJSONObject(i);
map = new HashMap<String, String>();
map.put("LocationID", c.getString("LocationID"));
map.put("Latitude", c.getString("Latitude"));
map.put("Longitude", c.getString("Longitude"));
map.put("LocationName", c.getString("LocationName"));
location.add(map);
}
} catch (JSONException e) {
e.printStackTrace();
}
googleMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.googleMap)).getMap();
Latitude = Double.parseDouble(location.get(0).get("Latitude").toString());
Longitude = Double.parseDouble(location.get(0).get("Longitude").toString());
LatLng coordinate = new LatLng(Latitude, Longitude);
googleMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);
googleMap.animateCamera(CameraUpdateFactory.newLatLngZoom(coordinate, 17));
for (int i = 0; i < location.size(); i++) {
Latitude = Double.parseDouble(location.get(i).get("Latitude").toString());
Longitude = Double.parseDouble(location.get(i).get("Longitude").toString());
String name = location.get(i).get("LocationName").toString();
MarkerOptions marker = new MarkerOptions().position(new LatLng(Latitude, Longitude)).title(name);
googleMap.addMarker(marker);
}
client2 = new GoogleApiClient.Builder(this).addApi(AppIndex.API).build();
}
public static String getHttpGet(String url) {
StringBuilder str = new StringBuilder();
HttpClient client = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(url);
try {
HttpResponse response = client.execute(httpGet);
StatusLine statusLine = response.getStatusLine();
int statusCode = statusLine.getStatusCode();
if (statusCode == 200) {
HttpEntity entity = response.getEntity();
InputStream content = entity.getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(content));
String line;
while ((line = reader.readLine()) != null) {
str.append(line);
}
} else {
Log.e("Log", "Failed to download result..");
}
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return str.toString();
}
@Override
public void onStart() {
super.onStart();
client2.connect();

Action.TYPE_VIEW,
