所以，我使用 cardview 在我的 android 应用程序的一个页面中创建一个片段页面。我正在使用 cardview 来获得一个整洁的方形布局，但是对于长文本，对于最后一段，它被 1 行截断，而且 layout_marginbottom 似乎也不起作用。发生什么事？

这是我的 fragmentpage.xml

<?xml version="1.0" encoding="utf-8"?>

这是我向下滚动之前和向下滚动之后的屏幕截图。顶部正确地有顶部边距，但底部似乎没有任何边距，并且还切断了一些文本。

您可以像这样插入一个空白视图：

 <View 
      android:layout_width="fill_parent"
      android:layout_height="20dp" />

// 根据您的要求设置高度

将此代码放入滚动视图的布局中（在 start 和 end 处）。

这样做：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

    android:padding="30dp" >
