Android - 警告Nested weights are bad for performance

原因: Layout weights require a widget to be measured twice. When a LinearLayout with non-zero weights is nested inside another LinearLayout with non-zero weights, then the number of measurements increase exponentially.

嵌套权值(Nested Weights), 权值会被计算两次, 改变时, 会依照比例进行改变.
