Android EditText 點選的時候，要進行二次處理，這個是為了，要有更好的使用者體驗

1. <EditText
2.     android:layout_width="fill_parent"
3.      android:layout_height="36dip"
4.      android:background="@drawable/bg_edittext"
5.      android:padding="5dip"
6.     android:layout_margin="36dip"
7.     android:textColorHint="#AAAAAA"
8.     android:textSize
   ="15dip"
9.     android:singleLine="true"
10.     android:hint="請輸入..."
11. />

bg_edittext_normal.xml(未獲得焦點時)

1. <?xmlversion="1.0"encoding="UTF-8"?>
2. <shapexmlns:android="http://schemas.android.com/apk/res/android">
3.     <solidandroid:color="#FFFFFF"/>
4.     <cornersandroid:radius="3dip"/>
5.     <
   stroke
6.         android:width="1dip"
7.         android:color="#BDC7D8"/>
