先上一下效果图
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) {

null);
mapView = (MapView) mapLayout.findViewById(R.id.map);
mapView.onCreate(savedInstanceState);

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，
