错误：不允许使用字符串类型（在'layout\u marginLeft'处，值为'fill\u parent'）。声明不应为此属性提供字符串值。必须以像素/dp/dip为单位给出整数值
ie）布局_marginLeft=“10px”我看到您的按钮呈线性布局。在这种情况下，您可以在子项（按钮）上使用android:layout\u权重设置。诀窍是不要在带有可变按钮数的线性布局上使用android:weightSum。 下面的示例将沿线性布局拉伸按钮。如果希望按钮大小保持不变，请将每个按钮包装在另一个线性布局中（该布局将保留布局权重属性）
我明白这一点-我只是希望它们的间距取决于可用空间的大小（因此它们在不同的屏幕大小上显示正确的间距）
