先看看效果圖
下面是2個動畫的xml文件
animation1.xml
<?xml version="1.0" encoding="utf-8"?> <!-- 根標簽為animation-list,其中oneshot代表着是否只展示一遍,設置為false會不停的循環播放動畫 根標簽下,通過item標簽對動畫中的每一個圖片進行聲明 android:duration 表示展示所用的該圖片的時間長度 --> <animation-list xmlns:android="http://schemas.android.com/apk/res/android" android:oneshot="true" > <item android:drawable="@drawable/icon1" android:duration="250"> </item> <item android:drawable="@drawable/icon2" android:duration="250"> </item> <item android:drawable="@drawable/icon3" android:duration="250"> </item> <item android:drawable="@drawable/icon4" android:duration="250"> </item> <item android:drawable="@drawable/icon5" android:duration="250"> </item> <item android:drawable="@drawable/icon6" android:duration="250"> </item> </animation-list>
animation2.xml
<?xml version="1.0" encoding="utf-8"?> <!-- 根標簽為animation-list,其中oneshot代表着是否只展示一遍,設置為false會不停的循環播放動畫 根標簽下,通過item標簽對動畫中的每一個圖片進行聲明 android:duration 表示展示所用的該圖片的時間長度 --> <animation-list xmlns:android="http://schemas.android.com/apk/res/android" android:oneshot="true" > <item android:drawable="@drawable/icon6" android:duration="250"> </item> <item android:drawable="@drawable/icon5" android:duration="250"> </item> <item android:drawable="@drawable/icon4" android:duration="250"> </item> <item android:drawable="@drawable/icon3" android:duration="250"> </item> <item android:drawable="@drawable/icon2" android:duration="250"> </item> <item android:drawable="@drawable/icon1" android:duration="250"> </item> </animation-list>
xml布局文件:
<?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" > <ImageView android:id="@+id/animationIV" android:layout_width="wrap_content" android:layout_height="wrap_content" android:padding="5px" android:src="@anim/animation1" android:scaleType="center"/> <Button android:id="@+id/buttonA" android:layout_width="fill_parent" android:layout_height="wrap_content" android:padding="5px" android:onClick="onClick" android:text="順序顯示" /> <Button android:id="@+id/buttonB" android:layout_width="fill_parent" android:layout_height="wrap_content" android:padding="5px" android:onClick="onClick" android:text="停止" /> <Button android:id="@+id/buttonC" android:layout_width="fill_parent" android:layout_height="wrap_content" android:padding="5px" android:onClick="onClick" android:text="倒序顯示" /> </LinearLayout>
