Search view is not working on map API

Search view is not working on map API - android

I'm using this code, and I'm getting false value in

Google map not loading completely in Android fragment (Partial loading issue)

I'm developing an Android application which requires Google maps to be loaded in a fragment.
The map loads only partially. Half of the map remains gray and doesn't load.
Please provide your suggestions. I'm not sure about the issue.
Below are the project files :

View v = inflater.inflate(R.layout.fragment_map, container, false);
mMapView = (MapView) v.findViewById(R.id.mapView);
mMapView.onCreate(savedInstanceState);
mMapView.onResume();// needed to get the map to display immediately
try {
MapsInitializer.initialize(getActivity().getApplicationContext());
} catch (Exception e) {
e.printStackTrace();
}
context = getContext();
DatabaseHelper databaseHelper = new DatabaseHelper(context, null, null, 0);
ArrayList<PropertyDetails> arrayList = databaseHelper.readData();
Log.d("PAVAN", "Details "+arrayList.get(0).getCity());
Log.d("PAVAN", "Details "+arrayList.get(0).getLatitude());
googleMap = mMapView.getMap();
for(int i = 0 ; i < arrayList.size() ; i++) {
// latitude and longitude
String PropertyType = arrayList.get(i).PropertyType;
String Address = arrayList.get(i).Address;
String City = arrayList.get(i).City;
Double LoanAmount = arrayList.get(i).LoanAmount;
Double APR = arrayList.get(i).APR;
Double MonthlyPayment = arrayList.get(i).MonthlyPayment;
Double Latitude = arrayList.get(i).getLatitude();
Double Longitude = arrayList.get(i).getLongitude();
// create marker
MarkerOptions marker = new MarkerOptions().position(
new LatLng(Latitude, Longitude)).title(PropertyType + "<br/>" + Address + "<br/>" +
City + '\n' + LoanAmount + '\n' + APR + "<br/>" + MonthlyPayment).snippet("" + APR).snippet("" + MonthlyPayment);
// Changing marker icon

Your code works perfect. You just have to move your device in the place where gps is available, because the place where you are testing your app may not have exposure to GPS satellite.
onLocationChanged() will be called once GPS is detected by the device

Check your project from there

But i think problem with manifest

I can only test in my device. The map is working fine but i cannot get my position on the center of the screen right away only clicking at the mylocationbutton. Somebody can help me?

Just declare a point where you want to center your point.
LatLng cur_Latlng = new LatLng(21.0000, 78.0000);
gm.moveCamera(CameraUpdateFactory.newLatLng(cur_Latlng));
gm.animateCamera(CameraUpdateFactory.zoomTo(4));
the desired zoom level is in the range of 2.0 to 21.0.

// try this
#Override
public void onLocationChanged(Location location) {
LatLng latlong = new LatLng(location.getLatitude(),
location.getLongitude());
googleMap.animateCamera(CameraUpdateFactory.newLatLng(latlong));
googleMap.animateCamera(CameraUpdateFactory.zoomBy(15));
}

Your min sdk is 8. You should use SupportMapFragment. Your class must extend FragmentActivtiy
Check the line above developers guide heading in the below link
https://developers.google.com/maps/documentation/android/reference/com/google/android/gms/maps/MapFragment
<fragment
class="com.google.android.gms.maps.SupportMapFragment"
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
Use SupportMapFragment
SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
GoogleMap mMap = fm.getMap();
Make sure you have added support library
Also make sure you imported the below
import android.support.v4.app.FragmentActivity;
import com.google.android.gms.maps.SupportMapFragment
To zoom
CameraUpdate update = CameraUpdateFactory.newLatLngZoom(latlong,20);
googleMap.moveCamera(update);

This is working Current Location with zoom for Google Map V2
double lat= location.getLatitude();
double lng = location.getLongitude();
LatLng ll = new LatLng(lat, lng);
googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(ll, 20));

Note that the My Location layer does not return any data. If you wish to access location data programmatically, use the Location API.
In your MainActivity (onCreate Method)
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(MainActivity.this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
On method onMapReady
#Override
public void onMapReady(GoogleMap googleMap) {
GoogleMap mMap = googleMap;
// Set blue point on the map at your cuurent location
mMap.setMyLocationEnabled(true);
// Show zoon controls on the map layer
mMap.getUiSettings().setZoomControlsEnabled(true);
//Show My Location Button on the map
mMap.getUiSettings().setMyLocationButtonEnabled(true);
}
on method onConnected
#Override
public void onConnected(Bundle bundle) {
mLastLocation = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);
if (mLastLocation != null) {
LocationListener.latlonInit= new LatLng(mLastLocation.getLatitude(),mLastLocation.getLongitude());
CameraPosition target = CameraPosition.builder().tilt(66.0f).target(LocationListener.latlonInit)
.zoom(MainActivity.ZOOM).build();
mMap.moveCamera(CameraUpdateFactory.newCameraPosition(target));
}
}

You class should extend Fragment Activity
public class MainActivity extends FragmentActivity {
//assign any arbitrary value to GPS_ERRODIALOG_REQUEST
private static final int GPS_ERRORDIALOG_REQUEST = 9001;
GoogleMap googlemap;
}
for Google Service Ok method I would do Following:
public boolean isGooglePlayOk(){
int isAvailable = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);
if (isAvailable == ConnectionResult.SUCCESS) {
return true;
}
else if(GooglePlayServicesUtil.isUserRecoverableError(isAvailable)){
Dialog dialog = GooglePlayServicesUtil.getErrorDialog(isAvailable, this, GPS_ERRORDIALOG_REQUEST);
dialog.show();
}
else {
Toast.makeText(this, "Can't connect to Goolge Play", Toast.LENGTH_SHORT).show();
}
return false;
}
In the .xml file, when you declare the fragment, you need to support Map Fragment since your min skd is 8:
<fragment
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:maps="http://schemas.android.com/apk/res-auto"
android:id="#+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />

activity_map.xml is for displaying map if condition is true for setMap else go to you regular activity_main.xml.
public class MainActivity extends FragmentActivity {
GoogleMap mMap;
if (isGooglePlayOk()) {
setContentView(R.layout.activity_map);
if (setMap()) {
mMap.setMyLocationEnabled(true);
}
else {
//your code
}
}
else {
setContentView(R.layout.activity_main);
}
method for setMap:
private boolean setMap() {
if (mMap == null) {
SupportMapFragment mapFrag =
(SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
mMap = mapFrag.getMap();
}
return (mMap != null);
}

If you want to automatically zoom to some point in google maps v2 u can do like this
private float previousZoomLevel = 13.00f;
LatLng zoomPoint = new LatLng(12.977286, 77.632720);
mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(zoomPoint,previousZoomLevel));
here previousZoomLevel is level of zoom

Android Maps API: Failed resolving interface

I implemented a map method using the Google Maps API. Yesterday, it was working fine. Since then, I've made absolutely no changes whatsoever to eclipse, any map related method (including views and the MapActivity class) or anything in the its corresponding entry in the manifest - the only thing I changed was to add a splash screen, thereby changing the launcher activity from MyLITactivity to SplashActivity.
My API key is in the manifest, and I've included the uses-library entry in the manifest.
When I run the app, logcat shows this:
05-06 16:12:04.855: I/dalvikvm(753): Failed resolving Lcom/mad/mylit/MapActivity; interface 486 'Lcom/google/android/gms/maps/GoogleMap$OnMapClickListener;'

}
}
If I comment out the OnMapClickListener and OnMapLongClickListener implements (and their corresponding methods) the error disappears.

Solved: I removed and re-imported all libraries, fixed project properties and did a clean-build.
Still have no idea why it worked yesterday and not today...

Project running but i cant see my location. I cant find where is may fault. To see Screenshot: http://sdrv.ms/Wyf1Z1 Thank u for helping.

in your layout add your actual 2.0 auth api key in android:apiKey="my api key" />, which you must be reated from api key console .
