TextView【练习】之自定义九键与全键盘

效果图

全键盘： 六排LinearLayout+每排6个TextView则完成布局。
九键： 三排LinearLayout+每排3个自定义的NineKeyboardLayout
自定义NineKeyboardLayout:
一个有两个TextView的Layout，称为NineTextViewLayout，一行显示数字，一行显示字母。
一个显示点击上下左右的包含ImageView的Layout作为PopWindow显示，称为MultiKeySelectPop.
主要思路：
NineTextViewLayout用于显示九键内容。
MultiKeySelectPop显示用户按下上下左右键的选择字母。
主要技术点：
在MutilKeySelectPop的字母位置显示上，主要测量内圆与外圆的大小，并确定其余字母的位置。

全键盘：
