android空間動畫

我再這里用到了動畫

先貼出代碼吧

//layout              

    android:layout_width="match_parent"

    android:layout_height="match_parent" >

        android:id="@+id/imgpic"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:scaleType="center"

        android:src="@drawable/left" >//圖片可更改

        android:id="@+id/toggleButton1"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:layout_alignParentBottom="true"

        android:layout_centerHorizontal="true"

        android:layout_marginBottom="141dp"

        android:text="ToggleButton" />

//動畫路徑 res/anim/tip.xml

        android:fromDegrees="0"  

        android:toDegrees="359"  

        android:duration="1000"  

        android:repeatCount="-1"  

        android:pivotX="50%"  

        android:pivotY="50%" />  

動畫的參數設置：

android:fromDegrees="0"   //起始角度

        android:toDegrees="359"   //結束的角度度數，負數表示逆時針，正數表示順時針。如2圈則比  //android:fromDegrees大720即可

        android:duration="1000"    //表示從android:fromDegrees轉動到android:toDegrees所花費的時間，    //單位為毫秒。可以用來計算速度。

        android:repeatCount="-1"  //重復的次數，負數表示一直旋轉

        android:pivotX="50%"      //旋轉中心的坐標

        android:pivotY="50%" /> 

//activity
