Question

我有一个自定义列表视图，其中微调器作为行的一个组件。我正在使用片段，所以我按照以下方式扩充布局：

this._inflater = LayoutInflater.from(context);

，其中

context = getActivity().getApplicationContext().

我对微调器的布局是：

<Spinner
    android:id="@+id/spTipoDispProteccion"
    android:layout_width="0dp"
    android:textColor="@color/NEGRO"
    android:layout_weight="3.1"
    style="@style/DropDownAltaFacil"
    android:spinnerMode="dialog"
    android:entries="@array/OPCIONES_TIPO_DISP_SEGURIDAD"
    android:layout_height="wrap_content"
    android:gravity="center_vertical"
    android:layout_gravity="center_vertical"
    android:layout_marginLeft="5dp" 
/>

当我选择微调器时，为了选择一个值，它会崩溃并向我显示错误添加窗口标记null。我尝试传递getActivity（）但不起作用。

有什么想法吗？

这是我的日志：
