recyclerView GridLayoutManager 中的图像显示不正确

Question

我正在尝试在 recyclerview 中显示 3 列的图像....但它们没有正确显示 This is the error

recyclerView = view.findViewById(R.id.recycler_view);
    recyclerView.setHasFixedSize(true);
    LinearLayoutManager mLayoutManager = new GridLayoutManager(getContext(), 3);
    recyclerView.setLayoutManager(mLayoutManager);
    postList = new ArrayList<>();
    myFotosAdapter = new MyFotosAdapter(getContext(), postList);
    recyclerView.setAdapter(myFotosAdapter);

这是recyclerview的xml代码

<androidx.recyclerview.widget.RecyclerView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:clipToPadding="false"

            app:layoutManager="androidx.recyclerview.widget.LinearLayoutManager"
            android:id="@+id/recycler_view"/>

你能试试这个解决方案吗

         <androidx.recyclerview.widget.RecyclerView
         android:id="@+id/recycler_view"/>
         android:layout_width="match_parent"
         android:layout_height="wrap_content"

app:layoutManager="androidx.recyclerview.widget.GridLayoutManager"

         app:spanCount="3" />
