This Exception occurred in
slidingMenu.attachToActivity(this, SlidingMenu.LEFT);
line when I try to show some extra information on Mark click. I want to show the content in sliding menu. "this" object refer to MapActivity class(my custom java class) that extends AppCompatActivity class. This method is in My MapActivity class which is responsible for initializing sliding menu:
private void initSlideMenu(){
slidingMenu = new SlidingMenu(this);
slidingMenu.setMode(SlidingMenu.RIGHT);
double dimension = Master.checkDimension(G.currentActivity);
Log.i("dimension", dimension + "");
if (dimension < 4)
slidingMenu.setBehindOffset(100);
else if (dimension >= 4 && dimension <= 5)
slidingMenu.setBehindOffset(300);
else if (dimension > 5)
slidingMenu.setBehindOffset(250);
slidingMenu.setFadeDegree(0.8f);
slidingMenu.setFadeEnabled(true);
slidingMenu.attachToActivity(this, SlidingMenu.LEFT);
if (dimension <= 6) {
slidingMenu.setSlidingEnabled(false);
}
View view = G.inflater.inflate(R.layout.map_details, null);
slidingMenu.setMenu(view);
}
and my layout file:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<fragment
android:name="com.google.android.gms.maps.MapFragment"
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</LinearLayout>
And My Java class:
public class MapActivity extends AppCompatActivity implements OnMapReadyCallback {
GoogleMap googleMap;

public boolean firstTime = true;

ArrayList<Double> yList = new ArrayList<>();

@Override

mapFragment.getMapAsync(this);
}
@Override
public void onMapReady(final GoogleMap map) {
Log.i("Position", "SS");
map.setMyLocationEnabled(true);
final BitmapDescriptor saharsunLocationIcon = BitmapDescriptorFactory.fromResource(R.drawable.saharsun_smal);
final BitmapDescriptor myLocationIcon = BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_RED);
// Check if we were successful in obtaining the map.
map.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() {
@Override

if (marker.getTitle().equals("I'm Hear")) {
MediaPlayer mPlayer2;
mPlayer2 = MediaPlayer.create(G.currentActivity, R.raw.cow_sound);
mPlayer2.start();
initSlideMenu();
Log.i("MARKER", marker.getTitle());
}
Log.i("MARKER", marker.getTitle());
return true;
}
});
if (map != null) {
map.setOnMyLocationChangeListener(new GoogleMap.OnMyLocationChangeListener() {
@Override
public void onMyLocationChange(Location location) {
// TODO Auto-generated method stub
Random random = new Random();
myLocation = new LatLng(location.getLatitude(),
location.getLongitude());
Log.i("Position", location.getLatitude() + " " + location.getLongitude());
if (firstTime) {
map.animateCamera(CameraUpdateFactory.newLatLngZoom(myLocation, 16));
map.addMarker(new MarkerOptions().position(
new LatLng(location.getLatitude(), location.getLongitude())).title("It's Me!")).setIcon(myLocationIcon);
for (int i = 0; i < 5; i++) {
double x = random.nextDouble() / 100 - 0.001 + location.getLatitude();
double y = random.nextDouble() / 100 - 0.001 + location.getLongitude();
xList.add(x);
yList.add(y);
map.addMarker(new MarkerOptions().position(
new LatLng(x, y)).title("I'm Hear")).setIcon(saharsunLocationIcon);
}
firstTime = false;
