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.Bitmap;
import android.graphics.Matrix;
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
private LinearInterpolator lir = new LinearInterpolator();
public RefreshProgress(Context context) {
super(context);
}
public RefreshProgress(Context context, AttributeSet attrs) {
super(context, attrs);
}
public void changeAnimation(int num){
m.reset();
//
Bitmap bitmap = ((BitmapDrawable) getResources().getDrawable(R.drawable.loading_rotate))
.getBitmap();
this.setImageBitmap(bitmap); //显示图像
//
m.setRotate(num);
Bitmap newBitmap = Bitmap.createBitmap(bitmap,0,0,bitmap.getWidth(),bitmap.getHeight(),m,true);
BitmapDrawable bd = new BitmapDrawable(newBitmap);
this.setImageDrawable(bd); //显示新的图像
}
//控制动画
public void Animation(){
RotateAnimation rotate = new RotateAnimation(0, 720, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
//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);
}
}
