试试这个

yourMapView.setVisibility(View.GONE);// to hide
并展示

yourMapView.setVisibility(View.VISIBLE);// TO SHOW
试试这个

 mMapView.setVisibility(View.INVISIBLE); //To INVISIBLE
在java代码中

布局_2.setVisibility(View.VISIBLE);//显示线性布局

布局_2.setVisibility(View.GONE);//隐藏线性布局

布局_1也一样

在xml代码中

我相信如果您只使用一个
MapView
并更新您显示的信息会更好。。除此之外,如果您想继续使用两个,则应该将它们视为<代码>视图< /代码>,并根据要显示的内容更改可见性。
