OSM Mapview：在屏幕上显示地理标记中的所有地理位置

Question

我按照这里的示例：How to set screen zoom by geopoints?

但我的问题是我的路线在mapview中非常小。它应该在边界附近结束。

以下代码的外观如下：

private void centerMap(ArrayList<GeoPoint> waypoints) {
    GeoPoint[] geoPoints = new GeoPoint[waypoints.size()];
    for(int i = 0; i<waypoints.size(); i++) {
        geoPoints[i] = waypoints.get(i);
    }

    int minLat = Integer.MAX_VALUE;
    int maxLat = Integer.MIN_VALUE;
    int minLon = Integer.MAX_VALUE;
    int maxLon = Integer.MIN_VALUE;

    //for (Point point : twoPoints) {
    for(GeoPoint point: geoPoints){
        int lat = (int) (point.getLatitude() * 1E6);
        int lon = (int) (point.getLongitude() * 1E6);

        maxLat = Math.max(lat, maxLat);
        minLat = Math.min(lat, minLat);
        maxLon = Math.max(lon, maxLon);
        minLon = Math.min(lon, minLon);
    }

    mapView.getController().zoomToSpan(Math.abs(maxLat - minLat), Math.abs(maxLon - minLon));
    mapView.getController().setCenter(new GeoPoint((maxLat + minLat) / 2, (maxLon + minLon) / 2));
}

<table>
    <thead>
        <tr>
            <th>Loan Type</th>
            <th>Amount Borrowed</th>
            <th>Current Payment</th>
            <th>Current Term</th>
            <th>Total Cost of Loan</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td></td>
            <td></td>
            <td></td>
            <td></td>
            <td></td>
        </tr>
    </tbody>
</table>
<script>
    var myObject = {balance: 10000, monthlyPayment: 98.41810662028588, total: 11810.172794434306};
    $('tbody tr').find('td:nth-child(specfic_tr_number)').html(myObject.balance);
</script>

请注意，在osmdroid中，lat / lon值现在默认为double。
