本文给大家分享高级UI特效仿直播点赞效果—一个优美炫酷的点赞动画，具体实现代码大家参考本文。

效果图如下：

攻克难点：

心形图片的路径等走向 心形图片的控制范围

部分代码如下：

通过AbstractPathAnimator定义飘心动画控制器

@Override

public void start(final View child, final ViewGroup parent) {

parent.addView(child, new ViewGroup.LayoutParams(mConfig.heartWidth, mConfig.heartHeight));

FloatAnimation anim = new FloatAnimation(createPath(mCounter, parent, 2), randomRotation(), parent, child);

anim.setDuration(mConfig.animDuration);

anim.setInterpolator(new LinearInterpolator());//启动动画

anim.setAnimationListener(new Animation.AnimationListener() {

@Override

public void onAnimationEnd(Animation animation) {

mHandler.post(new Runnable() {

@Override

public void run() {

parent.removeView(child);

}

});

mCounter.decrementAndGet();

}

@Override

public void onAnimationRepeat(Animation animation) {

}

@Override

public void onAnimationStart(Animation animation) {

mCounter.incrementAndGet();

}

});

anim.setInterpolator(new LinearInterpolator());

child.startAnimation(anim);

}

/**

* 根据图片设置bitmap

* @param color

* @return

*/

public Bitmap createHeart(int color) {

if (sHeart == null) {

sHeart = BitmapFactory.decodeResource(getResources(), mHeartResId);

}

if (sHeartBorder == null) {

sHeartBorder = BitmapFactory.decodeResource(getResources(), mHeartBorderResId);

}

Bitmap heart = sHeart;

Bitmap heartBorder = sHeartBorder;

Bitmap bm = createBitmapSafely(heartBorder.getWidth(), heartBorder.getHeight());

if (bm == null) {

return null;

}

Canvas canvas = sCanvas;

canvas.setBitmap(bm);

Paint p = sPaint;

canvas.drawBitmap(heartBorder, 0, 0, p);

p.setColorFilter(new PorterDuffColorFilter(color, PorterDuff.Mode.SRC_ATOP));

float dx = (heartBorder.getWidth() - heart.getWidth()) / 2f;

float dy = (heartBorder.getHeight() - heart.getHeight()) / 2f;

canvas.drawBitmap(heart, dx, dy, p);

p.setColorFilter(null);

canvas.setBitmap(null);

return bm;

}

如何创建一个path

public Path createPath(AtomicInteger counter, View view, int factor) {

Random r = mRandom;

int x = r.nextInt(mConfig.xRand);

int x2 = r.nextInt(mConfig.xRand);

int y = view.getHeight() - mConfig.initY;

int y2 = counter.intValue() * 15 + mConfig.animLength * factor + r.nextInt(mConfig.animLengthRand);

factor = y2 / mConfig.bezierFactor;

//随机xPoint

int xPointFactor = mRandom.nextInt(mConfig.xPointFactor);

x = xPointFactor + x;

x2 = xPointFactor + x2;

int y3 = y - y2;

y2 = y - y2 / 2;

Path p = new Path();

p.moveTo(mConfig.initX, y);

p.cubicTo(mConfig.initX, y - factor, x, y2 + factor, x, y2);

p.moveTo(x, y2);

p.cubicTo(x, y2 - factor, x2, y3 + factor, x2, y3);

return p;

}
