TypedValue的applyDimension，将android的各种单位转换为px的方法

   /**

* @param value The value to apply the unit to.
* @param metrics Current display metrics to use in the conversion --

*
* @return The complex floating point value multiplied by the appropriate
* metrics depending on its unit.

getDimension

方法功能

getDimension()是基于当前DisplayMetrics进行转换，获取指定资源id对应的尺寸。文档里并没说这里返回的就是像素，要注意这个函数的返回值是float，像素肯定是int。
getDimensionPixelSize()与getDimension()功能类似，不同的是将结果转换为int，并且小数部分四舍五入。
getDimensionPixelOffset()与getDimension()功能类似，不同的是将结果转换为int，并且偏移转换（offset conversion，函数命名中的offset是这个意思）是直接截断小数位，即取整（其实就是把float强制转化为int，注意不是四舍五入哦）。
深入分析

getDimension()调用的是TypedValue的complexToDimension方法
getDimensionPixelSize调用的是TypedValue的complexToDimensionPixelSize方法
getDimensionPixelOffset调用的是TypedValue的complexToDimensionPixelOffset方法
使用注意

大家根据实际情况，看看如果是四舍五入就调用getDimensionPixelSize()，如果是取整就调用getDimensionPixelOffset()。千万不要setWidth((int)getDimension()) 这么写哦！

Junk Dimension
A junk dimension is a convenient grouping of typically low-cardinality flags and indicators. By creating an abstract dimension, these flags and indicators are removed from the fact table while placing them into a useful dimensional framework.A
Junk Dimension is a dimension table consisting of attributes that do not belong in the fact table or in any of the existing dimension tables. The nature of these attributes is usually text or various flags, e.g.
non-generic comments or just simple yes/no or true/false indicators. These kinds of attributes are typically remaining when all the obvious dimensions in the business process have been identified and thus the designer is faced with the challenge of where
to put these attributes that do not belong in the other dimensions.
Degenerate Dimension
A degenerate dimension is a key, such as a transaction number, invoice number, ticket number, or bill-of-lading number, that has no attributes and hence does not join to an actual dimension table. Degenerate dimensions are very common when the grain of a
fact table represents a single transaction item or line item because the degenerate dimension represents the unique identifier of the parent. Degenerate dimensions often play an integral role in the fact table's primary key.
e.g. composite keys
