预期结果（在Android 4.4.2平板电脑上正常工作，代码如下）

实际结果（在操作系统>=8.1.0的多部手机上测试）

尝试使用如下填充：

<RelativeLayout
            android:id="@+id/firstLayout"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:paddingLeft="someDp"   ->>>> Padding
            android:paddingRight="someDp" ->>>> Padding
            android:layout_above="@+id/horizontal_divider"
            android:layout_below="@id/toolbar"
            android:gravity="center">
    <TableLayout
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:id="@+id/tblLayout"
                android:gravity="center"
                android:shrinkColumns="*"
                android:padding="0dip"
                android:layout_margin="0dip"
                android:layout_centerInParent="true"
                android:layout_centerHorizontal="true"
                android:layout_centerVertical="true"></TableLayout>
</RelativeLayout >

填充 android:paddingRight=“someDp”->>>>填充 android:layout_Upper=“@+id/水平分隔符” android:layout_下方=“@id/toolbar” android:gravity=“center”>

我已尝试了您的代码，但无法复制此代码

对我来说，你的代码运行良好，请检查输出

根据我的意见，你应该使用

您应该将

RecyclerView

与

遵循此示例代码

在活动布局xml文件中添加一个recyclerview

创建垂直网格布局管理器

参数

上下文上下文：当前上下文将用于访问资源

spanCount int:网格中的列数

像这样创建一个适配器类

@如果我们想使用tableview。你能指出这个解决方案有什么问题吗？为什么它可以在4个操作系统上工作而不能在8个操作系统上工作？对我来说，你的代码工作得很好检查输出&&&&&@NileshRathod-我使用的映像有问题吗？您的项目中使用的图像尺寸是多少？我使用了64*64 png imageTry和开发者选项->绘图->显示布局边界。在那里你可以看到什么是什么，表格的大小，表格中的视图，蓝色的方块，你可以了解需要修改的内容。
