问题
Created i model like in answer. Also added tags in markers:
MarkerTag tag = new MarkerTag();
Marker marker = map.addMarker(new MarkerOptions()
.position(new LatLng(47.045029, 28.861427))
.title("Marker")
.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE))
.snippet("Population: 4,137,400"));
tag.setEmail("first@gmail.com");
tag.setPhoneNumber("+37369490007");
marker.setTag(tag);
Marker marker2 = map.addMarker(new MarkerOptions()
.position(new LatLng(47.000327, 28.867950))
.title("Marker")
.snippet("Population: 4,137,400 fdfsfsfsdfsfdsfsfssfsfsfsfsfs"));
tag.setEmail("second@gmail.com");
tag.setPhoneNumber("+37368750588");
marker2.setTag(tag);
Marker marker3 = map.addMarker(new MarkerOptions()
.position(new LatLng(47.024204, 28.889236))
.title("Marker")
.snippet("Population: 4,137,400 /n dasdasdas d"));
tag.setEmail("three@gmail.com");
tag.setPhoneNumber("+37369339092");
marker3.setTag(tag);
And added my methods:
private void makeCall(Marker marker) {
MarkerTag tag = ((MarkerTag)marker.getTag());
if (tag != null) {
Intent call = new Intent(Intent.ACTION_DIAL);
call.setData(Uri.parse("tel:" + String.valueOf(tag.getPhoneNumber())));
startActivity(call);
}
}
private void sendEmail(Marker marker) {
MarkerTag tag = ((MarkerTag)marker.getTag());
if (tag != null) {
Intent intent = new Intent(Intent.ACTION_SENDTO);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_SUBJECT, "subject");
intent.putExtra(Intent.EXTRA_TEXT, "text");
intent.setData(Uri.parse("email:" + String.valueOf(tag.getEmail())));
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
checkAndStart(this, intent, R.string.action_settings);
}
}
But now when i press on markers i get just one number, this
37369339092 and when i try to send email i catched the error : 233 26548-26548/com.vm.sai E/AndroidRuntime: FATAL EXCEPTION: main Process: com.vm.sai, PID: 26548 java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.Object com.google.android.gms.maps.model.Marker.getTag()' on a null object reference at com.vm.sai.activities.MapsActivity.sendEmail(MapsActivity.java:168) at com.vm.sai.activities.MapsActivity.-wrap1(MapsActivity.java) at com.vm.sai.activities.MapsActivity$2.onClickConfirmed(MapsActivity.java:92) at com.vm.sai.utils.OnInfoWindowElemTouchListener$1.run(OnInfoWindowElemTouchListener.java:84) at android.os.Handler.handleCallback(Handler.java:815) at android.os.Handler.dispatchMessage(Handler.java:104) at android.os.Looper.loop(Looper.java:194) at android.app.ActivityThread.main(ActivityThread.java:5637) at java.lang.reflect.Method.invoke(Native Method) at java.lang.reflect.Method.invoke(Method.java:372) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:959) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:754)

The .setTag()
accept an object
. So, in order to add more information in there you just have to create your own TagObject, lets call it MarkerTag;
public class MarkerTag {
private String email;
private String phoneNumber;
public MarkerTag() {
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getPhoneNumber() {
return phoneNumber;
}
public void setPhoneNumber(String phoneNumber) {
this.phoneNumber = phoneNumber;
}
}
Then you just add it to your marker as a tag:
MarkerTag yourMarkerTag = new MarkerTag();
yourMarkerTag.setEmail("someemail@gmail.com");
yourMarkerTag.setPhoneNumber("+15552345353");
marker.setTag(yourMarkerTag);
Now to get it back you just have to make sure that you are getting the right
if(null != marker.getTag()){
if(marker.getTag() instanceof MarkerTag){
MarkerTag yourMarkerTag = ((MarkerTag)marker.getTag());
Toast.makeText(getActivity, yourMarkerTag.getEmail() , Toast.LENGTH_SHORT).show();
Toast.makeText(getActivity, yourMarkerTag.getPhoneNumber() , Toast.LENGTH_SHORT).show();
}
}
