ScrollView抛出错误消息

Question

我正在使用以下代码创建视图

    </ScrollView>
</LinearLayout>

我想在视图组中显示文本视图后绘制一条线。我遇到的问题是它会抛出错误scrollview can have only one direct child。但我试图在最后绘制线条。怎么做？当我在模拟器上运行它时，我的图像视图也不可见。

Answer 1

错误解释了自己不能将多个视图作为直接子项滚动视图。您正在将scrolllayout和视图直接放在scrollview中。它只能将一个视图作为直接子视图。所以将最外面的linearlayout包围起来，然后在另一个垂直方向的线性布局中查看

删除ImageView的layout_weight属性，如下所示：

<ImageView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:id="@+id/imageView4"
                android:src="@drawable/ic"
                android:layout_marginRight="10dp"/>
