我們可以使用selector來實現Button的特效,:
預設情況
獲得焦點的時候
點擊按鈕
main.xml
Xml代碼
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="按下或者獲得焦點Button會變不同顏色"
<SPAN style="COLOR: #ff0000">android:textColor="@color/button_text" </SPAN>/>
</LinearLayout>

<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="按下或者獲得焦點Button會變不同顏色"

XML 檔案儲存在res/color/button_text.xml
Xml代碼
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_pressed="true" android:color="#ffff0000"/> <!-- pressed -->
<item android:state_focused="true" android:color="#ff0000ff"/> <!-- focused -->
