无法在 Android Google 地图中获取 addMarker 上的片段搜索列表

Question

我在如何使用 onQueryTextSubmit 和 onQueryTextChange 方面遇到问题，我想要的是使用我的 addMarker 上的代码段获得可搜索的车牌号。我现在的问题是我的 onQueryTextSubmit 下是区分大小写的错误值。但是，我在列表中添加了我的标记，I am getting always the last value not all values. 请。帮助

        mMapFragment.animateCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(latitude, longitude), 9.0f));

                latitudeG = marker.getPosition().latitude;

                marker.showInfoWindow();

                BottomSheetDialogFragment bottomSheetDialogFragment = new BottomSheetModalFragment(activity);
                bottomSheetDialogFragment.show(getFragmentManager(), bottomSheetDialogFragment.getTag());

    }

    public void onMapReady(GoogleMap googleMap) {
        mMapFragment = googleMap;
 /*       LatLng latlong = new LatLng(12.405888, 123.273419);
        CameraUpdate cameraPosition = CameraUpdateFactory.newLatLngZoom(latlong, 16);
        mMap.moveCamera(cameraPosition);
        mMap.animateCamera(cameraPosition);*/

        new GetVehicles().execute();
        mMapFragment.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(12.405888, 123.273419), 6));
//        mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(12.405888, 123.273419), 13));

        setUpMap();
    }

这里我想将search title="Plate No."经纬度的值传递给LatLng值。

 public boolean onQueryTextSubmit(String query) {
    centerMarker(query);
    for(Marker m : list) {
        System.out.println(m.getSnippet() + m.getTitle() + m.getPosition() + " snippet");
        if(m.getSnippet().equals(query)) {
            Toast.makeText(this, "You searched for: " + query , Toast.LENGTH_SHORT).show();
            mMapFragment.animateCamera(CameraUpdateFactory.newLatLngZoom(m.getPosition(), 9.0f));
            break; // stop the loop
        }
    }
    return true;
}

@Override
public boolean onQueryTextChange(String newText) {
    return false;
}

I am getting always the last value not all values.

您只能得到 一个值（...可能），因为每次调用 createMarker(d, d2, plate_num)

的方法时，您都会创建一个全新的列表

public void createMarker(Double latitude, final Double longitude, String Plate_num) {
        BitmapDescriptor image = BitmapDescriptorFactory.fromResource(R.drawable.bus);

        // list = new ArrayList<Marker>(); // Stop doing this!
