我正在使用places API在我的地图上将地点显示为标记，然后我希望能够点击其中一个标记并将其信息保存到firebase。在我将其保存到firebase的那一刻，它保存了我当前的位置而不是标记lat long。请帮忙:)
mStar是点击的按钮，点击后我想将位置添加到firebase ...
mStar.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//Toast.makeText(NearbyLocations.this, "Rating......", Toast.LENGTH_SHORT).show();
/*latitude = marker.getPosition().latitude;
longitude = marker.getPosition().longitude;*/
LocationInformation locInfo = new LocationInformation(name, latitude, longitude);
FirebaseUser user = mAuth.getCurrentUser();
String userID = user.getUid();
saveLocations.child(userID).child("Locations").setValue(locInfo)
.addOnSuccessListener(new OnSuccessListener<Void>() {
@Override
public void onSuccess(Void aVoid) {
Toast.makeText(NearbyLocations.this, "Location saved", Toast.LENGTH_LONG).show();
}
})
.addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
Toast.makeText(NearbyLocations.this, "Error location not saved", Toast.LENGTH_LONG).show();
}
});
}
});
这是评论中要求的全班..谢谢!!!!!

通过查看你的代码我发现你在latitude中分配longitude和void onLocationChanged(Location location)，这就是为什么你在点击星星时获得当前位置的原因。
你应该在标记的onclick中分配latitude和longitude，如下所示。
mMap.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() {
@Override
public boolean onMarkerClick(Marker marker) {
latitude = marker.getPosition().latitude;
longitude = marker.getPosition().longitude;
return true;
}
});
删除任何其他任务，然后单击星形按钮，您应该获得正确的位置。
