[英]Google Place Picker on Android - limit area/radius
Is there a way to limit Google Place Picker area that user is able to pick his/her place? 有没有办法限制用户可以选择他/她的位置的Google Place Picker区域?
Something like radius from current location. 像当前位置的半径。
I don't believe there is documentation to control the selection in the actual Place Picker
intent, but you could do it in the `onActivityResult. 我不相信有文档可以控制实际的
Place Picker
意图中的Place Picker
,但你可以在`onActivityResult中完成。 Here is an example: 这是一个例子:
int PLACE_PICKER_REQUEST = 1;
String toastMsg;
Location selectedLocation = new Location(provider);
Location currentLocation = new Location(provider);
double maxDistance = 10;
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == PLACE_PICKER_REQUEST) {
if (resultCode == RESULT_OK) {
Place place = PlacePicker.getPlace(data, this);
selectedLocation.setLatitude(place.getLatLng().latitude);
selectedLocation.setLongitude(place.getLatLng().longitude);
if(selectedLocation.distanceTo(currentLocation) > maxDistance) {
toastMsg = "Invalid selection, please reselect your place";
// Runs the selector again
PlacePicker.IntentBuilder builder = new PlacePicker.IntentBuilder();
startActivityForResult(builder.build(this), PLACE_PICKER_REQUEST);
} else {
// Result is fine
toastMsg = String.format("Place: %s", place.getName());
}
Toast.makeText(this, toastMsg, Toast.LENGTH_LONG).show();
}
}
}
You can change maxDistance
to the maximum distance you want the user's selection to be from their location. 您可以将
maxDistance
更改为您希望用户从其位置选择的最大距离。 Hope it helps! 希望能帮助到你!
