Mapbox在片段上的膨胀视图

sea*_*ean 10 java xml android android-fragments mapbox

我有问题在Android片段上膨胀Mapbox MapView.当我在Activity上使用相同的代码时(除了Activity和Fragment之间的标准差异),我可以正确加载MapView,但不能在Fragment上加载.

Mapbox 在这里也有一个MapFragment类,但我不确定如何在Fragment中正确使用它(该示例仍然在Activity中); 使用Google Maps API,我可以在片段上使用MapView而不会出现问题.

是指Java行:

fragmentLayout = inflater.inflate(R.layout.fragment_map, container, false);
