仿消灭星星烟花爆炸效果

烟花效果，可以改变参数和图片改变烟花效果。

1.大烟花爆炸效果如下

2.小烟花爆炸效果如下

3.代码如下

3.1烟花粒子元素

import android.graphics.Bitmap;
public class Element {
    public int color;
    public Double direction;
    public float speed;
    public float x = 0;
    public float y = 0;
    public Bitmap bitmap;

    public Element(int color, Double direction, float speed,Bitmap bitmap){
        this.color = color;
        this.direction = direction;
        this.speed = speed;
        this.bitmap = bitmap;
    }
}
