Android高級(jí)UI特效仿直播點(diǎn)贊動(dòng)畫效果
本文給大家分享高級(jí)UI特效仿直播點(diǎn)贊效果—一個(gè)優(yōu)美炫酷的點(diǎn)贊動(dòng)畫，具體實(shí)現(xiàn)代碼大家參考本文。
目前成都創(chuàng)新互聯(lián)已為上千的企業(yè)提供了網(wǎng)站建設(shè)、域名、網(wǎng)絡(luò)空間、網(wǎng)站托管、服務(wù)器租用、企業(yè)網(wǎng)站設(shè)計(jì)、碧江網(wǎng)站維護(hù)等服務(wù)，公司將堅(jiān)持客戶導(dǎo)向、應(yīng)用為本的策略，正道將秉承"和諧、參與、激情"的文化，與客戶和合作伙伴齊心協(xié)力一起成長(zhǎng)，共同發(fā)展。
效果圖如下：
攻克難點(diǎn)：
心形圖片的路徑等走向 心形圖片的控制范圍
部分代碼如下：
通過(guò)AbstractPathAnimator定義飄心動(dòng)畫控制器
@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());//啟動(dòng)動(dòng)畫
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);
}
/**
* 根據(jù)圖片設(shè)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;
}如何創(chuàng)建一個(gè)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;
//隨機(jī)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;
