话不多少,贴一下fragment的代码,高德地图的jar包导入就不细说了,官方很详细了,

错误报告:The specified child already has a parent. You must call removeView() on the child’s parent first.

if (mapLayout == null) {
            mapLayout = inflater.inflate(R.layout.locationmodesource_activity,
                    null);
            mapView = (MapView) mapLayout.findViewById(R.id.map);
            mapView.onCreate(savedInstanceState);
            if (aMap == null) {
                aMap = mapView.getMap();
                // init();
                setUpMap();
                mLocationErrText = (TextView) mapLayout
                        .findViewById(R.id.location_errInfo_text);
                imgbtn = (ImageButton) mapLayout
                        .findViewById(R.id.imageButton1);
            }
        } else {
            if (mapLayout.getParent() != null) {
                ((ViewGroup) mapLayout.getParent()).removeView(mapLayout);
            }
        }
        return mapLayout;
之前
mLocationErrText = (TextView) mapLayout
                        .findViewById(R.id.location_errInfo_text);
                imgbtn = (ImageButton) mapLayout
                        .findViewById(R.id.imageButton1);

这句放错了位置,导致按钮监听事件失效,
