ListView的简单测试（记事本界面）

记下代码，方便以后查看。还没简化代码，仅仅是有界面。一下用到的是SimpleAdapter

首先是xml文件 activity_main.xml

这是总体框架布局文件

<?xml version="1.0" encoding="utf-8"?>  
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"  
    android:layout_width="fill_parent"  
    android:layout_height="fill_parent"  
    >  
    <ListView  
    android:id="@+id/list"  
    android:layout_width="fill_parent"  
    android:layout_height="wrap_content"  
    android:layout_alignParentTop="true"
    /> 

    <LinearLayout
        android:layout_width="fill_parent"  
        android:layout_height="wrap_content"  
        android:orientation="horizontal"
        android:layout_alignParentBottom="true"
        >        
        <Button 
            android:id="@+id/one"
            android:layout_height="wrap_content"
            android:layout_width="0dip"
            android:layout_weight="1"
            android:text="主界面"
            />
        <Button
            android:id="@+id/two"
            android:layout_height="wrap_content"
            android:layout_width="0dip"
            android:layout_weight="1"
            android:text="新增"
            />
        <Button
            android:id="@+id/three"
            android:layout_height="wrap_content"
           android:layout_width="0dip"
            android:layout_weight="1"
            android:text="查询"
            />
        <Button
            android:id="@+id/four"
            android:layout_height="wrap_content"
           android:layout_width="0dip"
            android:layout_weight="1"
            android:text="创建分类"
            />    
        </LinearLayout>                                     
</RelativeLayout>  

另外的xml是ListView布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/Allpower"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >
 
<RelativeLayout
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    >
        <TextView 
            android:id="@+id/lvw_custom_name"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"            
            android:layout_marginLeft="10dip"            
            android:layout_marginTop="5dip"
            android:textSize="25dip"
            />
        <TextView 
            android:id="@+id/lvw_custom_description"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentRight="true"
            android:layout_marginRight="10dip"
            android:textSize="25dip"
            />
</RelativeLayout>
</LinearLayout>
