MainActivity
extends
Activity
{
/*
* 1.ems 输入长度
* 2.inputType 输入类型
*
* 3.completeTextView设置：
* android:completionThreshold="1" 设置从第几个字母开始查询记录
*
* 4.<requestFocus />默认获得焦点
*
* 5.复用控件的方法：可再设置属性
* <include layout="@layout/relayout"
* android:layout_width="match_parent"
* android:layout_height="match_parent"
* android:layout_below="@+id/autoCompleteTextView1" />
*
* 6.当根布局是framelayout时，可以使用merge复用系统的布局，合并重复的layout
* <merge xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
* </merge>
