阅读《Android 中注解的使用》

# 0x01 读完后主要想了解所有的注解。
官方文档[注解支持库](https://developer.android.google.cn/topic/libraries/support-library/features.html#annotations)
转到
(https://developer.android.google.cn/reference/android/support/annotation/package-summary.html)
# 0x02 汉化 annotation 包
## 为 package-summary.html 生成伪翻译文件
```
java -jar "D:\xx\software\program\OmegaT_4.1.2_01_Beta_Without_JRE\OmegaT2.jar" "D:\workspace\TranslatorX\AndroidSdkDocs" --mode=console-createpseudotranslatetmx --pseudotranslatetmx=project_save.tmx --pseudotranslatetype=equal

## 3.1 所有的资源类型
通过 (https://developer.android.google.cn/reference/android/R.html) 知道有
class R.anim
class R.animator
class R.array
class R.attr
class R.bool
class R.color
class R.dimen
class R.drawable
class R.fraction
class R.id
class R.integer
class R.interpolator
class R.layout
class R.menu
class R.mipmap
class R.plurals
class R.raw
class R.string
class R.style
class R.styleable
class R.transition
class R.xml
通地(https://developer.android.google.cn/guide/topics/resources/available-resources.html)了解一下
## 3.1.1 fraction
android.content.res.Resources#getFraction
```
Retrieve a fractional unit for a particular resource ID.
Parameters
id int: The desired resource identifier, as generated by the aapt tool. This integer encodes the package, type, and resource entry. The value 0 is an invalid identifier.
base int: The base value of this fraction. In other words, a standard fraction is multiplied by this value.
pbase int: The parent base value of this fraction. In other words, a parent fraction (nn%p) is multiplied by this value.
```
如果是标准小数，会乘以 base ，如果是 nn%p 的形式，会乘以 pbase。
源码为
```
android.content.res.Resources#getFraction
android.util.TypedValue#complexToFraction
public static float complexToFraction(int data, float base, float pbase)
{
switch ((data>>COMPLEX_UNIT_SHIFT)&COMPLEX_UNIT_MASK) {
case COMPLEX_UNIT_FRACTION:
return complexToFloat(data) * base;
case COMPLEX_UNIT_FRACTION_PARENT:
return complexToFloat(data) * pbase;
}
return 0;
}
```
## 3.1.2 interpolator
(https://developer.android.google.cn/guide/topics/resources/animation-resource.html#Tween) 中有介绍
## 3.1.3 plurals
(https://developer.android.google.cn/guide/topics/resources/string-resource.html#Plurals)
* android.content.res.Resources#getQuantityText
* android.content.res.Resources#getQuantityString(int, int)
* android.content.res.Resources#getQuantityString(int, int, java.lang.Object...)
## 3.1.4 transition
[转换可绘制对象](https://developer.android.google.cn/guide/topics/resources/drawable-resource.html#Transition)
(https://developer.android.google.cn/reference/android/graphics/drawable/TransitionDrawable.html)
## 3.1.5 xml
# 3.2 音标
* dimension
* fraction [ˈfrækʃn]
* interpolator[ɪn'tɜ:pəʊleɪtə]
* plural [ˈplʊərəl]
* quantity [ˈkwɒntəti]
