EasyDemo*ListView在Fragment中使用的方法

注意：fragment中使用listview和activity中不一样

1.fragment布局中必须包含id"@android:id/list"(在代码中则是list)的ListView

2.fragment要extends ListFragment 而不是Fragment

3.只能使用SimpleAdapter或者SimpleCursorAdapter作为适配器

4.直接使用ListFragment的setListAdapter()来设置适配器

上代码: 

1>me.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

    android:orientation="vertical" >

    <ListView
        android:id="@id/android:list"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >

    </ListView>

</LinearLayout>

2>me_function_item.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal" >

    <ImageView
        android:id="@+id/functionIcon"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" />

    <TextView
        android:id="@+id/functionName"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="TextView" />

</LinearLayout>

3>MeFragment.java
