修改EditText的光标颜色

在使用EditText的XML 文件中加入一个属性：

android:textCursorDrawable="@null"

android:textCursorDrawable   这个属性是用来控制光标颜色的，

"@null"   是作用是让光标颜色和text color一样

android:textCursorDrawable 的用法可以查看android sdk

public static final int TextView_textCursorDrawable

Reference to a drawable that will be drawn under the insertion cursor.

Must be a reference to another resource, in the form "@[+][package:]type:name" or to a theme attribute in the form "?[package:][type:]name".

This corresponds to the global attribute resource symbol textCursorDrawable.

Constant Value: 70 (0x00000046)
