直接将RefreshProgress添加进xml中当做ImageView就能使用
package com.example.administrator.superrefresh;
import android.content.Context;

import android.graphics.drawable.BitmapDrawable;
import android.util.AttributeSet;
import android.view.animation.Animation;
import android.view.animation.LinearInterpolator;
import android.view.animation.RotateAnimation;
import android.widget.ImageView;

public class RefreshProgress extends ImageView {
private Matrix m = new Matrix();
//匀速加速器

public RefreshProgress(Context context) {
super(context);

public RefreshProgress(Context context, AttributeSet attrs) {

}
public void changeAnimation(int num){

public void Animation(){

//默认为0，为-1时一直循环动画
rotate.setRepeatCount(-1);
//添加匀速加速器
rotate.setInterpolator(lir);
rotate.setDuration(2000);
rotate.setFillAfter(true);
this.startAnimation(rotate);
}
}
