state_activated and ListView item選中效果

首先編寫selector：

<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:state_focused="true"    android:state_pressed="true" android:drawable="@color/headers_layout_bg_color" />
    <item android:state_focused="false"   android:state_pressed="true" android:drawable="@color/headers_layout_bg_color" />
    <item android:state_activated="true" android:drawable="@drawable/list_section_divider_holo_light" />
    <item android:drawable="@color/transparent" />


</selector>

接着在item layout中設置背景：

android:background=

最後定義ListView的選擇模式：

listView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
