Android上的Google Place Picker - 限制區域/半徑

Question

有沒有辦法限制用戶可以選擇他/她的位置的Google Place Picker區域？

像當前位置的半徑。

我不相信有文檔可以控制實際的Place Picker意圖中的Place Picker ，但你可以在`onActivityResult中完成。 這是一個例子：

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();
        }
    }
}

您可以將maxDistance更改為您希望用戶從其位置選擇的最大距離。 希望能幫助到你！
