具體含義是：

duration：時(shí)間</span>

fromDegrees="0"：從幾度開始轉(zhuǎn)</span>t

oDegrees="360" ：旋轉(zhuǎn)多少度</span>

pivotX="50%：旋轉(zhuǎn)中心距離view的左頂點(diǎn)為50%距離，

pivotY="50%：距離view的上邊緣為50%距離

repeatCount="-1"：重復(fù)次數(shù)，-1為一直重復(fù)

repeatMode="restart"：重復(fù)模式，restart從頭開始重復(fù)

布局文件代碼沒變，依舊是：放一個(gè)控件就行了

<com.example.circleimageview.CircleImageView 
 android:id="@+id/imageview"
 android:layout_width="100dp"
 android:layout_height="100dp"
 android:layout_centerInParent="true"
 android:src="@drawable/control_image"
 />
</RelativeLayout>

你也可以寫成一個(gè)普通的控件都可以實(shí)現(xiàn)旋轉(zhuǎn)

復(fù)制代碼代碼如下:

<span style="font-family: Arial, Helvetica, sans-serif;">package com.example.circleimageview;</span>import android.app.Activity;

import android.os.Bundle;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
import android.view.animation.LinearInterpolator;
import android.widget.ImageView;

public class MainActivity extends Activity {

 @Override
 protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);
 
 ImageView imageView = (ImageView) findViewById(R.id.imageview);
 //動(dòng)畫
  Animation animation = AnimationUtils.loadAnimation(this, R.anim.img_animation);
 LinearInterpolator lin = new LinearInterpolator();//設(shè)置動(dòng)畫勻速運(yùn)動(dòng)
 animation.setInterpolator(lin);
 imageView.startAnimation(animation);
 }

}

是不是很簡單，運(yùn)行效果如下：錄制的有點(diǎn)問題，實(shí)際上是勻速地。
