android之使用ListView實現多菜單功能

我們知道很多軟件都有設置菜單項如微信墨跡天氣等的設置界面。當設置里有很多選項這時我們可以選擇使用ListView實現。

布局文件如下：

    <?xml version="1.0" encoding="utf-8"?>  
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"  
        android:orientation="vertical"  
        android:layout_width="fill_parent"  
        android:layout_height="fill_parent"  
        android:background="@drawable/splash_background"  
        >  
        <ListView android:id="@+id/more_List"  
            android:layout_width="fill_parent"  
            android:layout_height="fill_parent"  
            android:divider="@drawable/list_bottom_line"  
            android:listSelector="#00000000"  
            android:cacheColorHint="#00000000">  
        </ListView>  
    </LinearLayout>  

item的布局：

<?xml version="1.0" encoding="utf-8"?>  
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"  
    android:orientation="horizontal"  
    android:layout_width="wrap_content"  
    android:layout_height="wrap_content"  
    android:padding="8dip"  
    android:background="@drawable/list_item"  
    >  
    <ImageView android:id="@+id/item_icon"  
        android:layout_width="wrap_content"  
        android:layout_height="wrap_content"  
    />  
    <TextView android:id="@+id/more_item_text"  
        android:layout_marginLeft="10dip"  
        android:textSize="20dip"  
        android:textColor="#000000"  
        android:layout_width="wrap_content"  
        android:layout_height="wrap_content"/>  
    <ImageView android:id="@+id/item_image"  
        android:layout_marginTop="5dip"  
        android:layout_marginLeft="10dip"  
        android:layout_width="wrap_content"  
        android:layout_height="wrap_content"  
        android:background="@drawable/triangle"  
    />  
</LinearLayout>
