在谷歌地圖API V2在android應用程序中工作時,我想有兩個標記一個用於源和一個目標。我將全局引用設置爲兩個標記,當我移動到某個其他位置並使用destinationMarker.remove()
刪除目標標記時,它不適用於我。它不會刪除上一個標記。.remove()不工作在Android谷歌地圖api v2
代碼:
//Global references
Marker sourceMarker;
Marker destinationMarker;
...
...
public void geoLocate(View v) throws IOException{
hideSoftKeyBoard(v);
EditText et = (EditText)findViewById(R.id.editText1);
String Location = et.getText().toString();
if(Location.length() == 0){
Toast.makeText(this, "Please specify a Location", Toast.LENGTH_LONG).show();
return;
}
Geocoder gc = new Geocoder(this);
List<Address> list = gc.getFromLocationName(Location, 1);
Address add = list.get(0);
String locality = add.getLocality();
Toast.makeText(this, locality, Toast.LENGTH_LONG).show();
double lat = add.getLatitude();
double lng = add.getLongitude();
gotoLocation(lat, lng, DEFAULT_ZOOM);
if(destinationMarker != null){
//removing marker if exists
destinationMarker.remove();
}
MarkerOptions options = new MarkerOptions().title(locality).position(new LatLng(lat,lng));
destinationMarker = mMap.addMarker(options);
}
試着用'mMap.clear();' – Rami
我不想清除我的其他標誌物即sourceMarker –
