前兩天我們這邊的頭兒給我說仰迁,有個(gè) gif 動(dòng)效很不錯(cuò)伸但,可以考慮用來做項(xiàng)目里的loading萍悴,問我能不能實(shí)現(xiàn)腻异,看了下效果確實(shí)不錯(cuò)缎玫,也還比較有新意民轴,復(fù)雜度也不是非常高,所以就花時(shí)間給做了踊谋,我們先一起看下原gif圖效果:
從效果上看蝉仇,我們需要考慮以下幾個(gè)問題:
- 葉子的隨機(jī)產(chǎn)生;
- 葉子隨著一條正余弦曲線移動(dòng);
- 葉子在移動(dòng)的時(shí)候旋轉(zhuǎn)轿衔,旋轉(zhuǎn)方向隨機(jī)沉迹,正時(shí)針或逆時(shí)針;
- 葉子遇到進(jìn)度條害驹,似乎是融合進(jìn)入鞭呕;
- 葉子不能超出最左邊的弧角;
- 葉子飄出時(shí)的角度不是一致裙秋,走的曲線的振幅也有差別琅拌,否則太有規(guī)律性,缺乏美感摘刑;
總的看起來进宝,需要注意和麻煩的地方主要是以上幾點(diǎn),當(dāng)然還有一些細(xì)節(jié)問題枷恕,比如最左邊是圓弧等等党晋;
那接下來我們將效果進(jìn)行分解,然后逐個(gè)擊破:
整個(gè)效果來說徐块,我們需要的圖主要是飛動(dòng)的小葉子和右邊旋轉(zhuǎn)的風(fēng)扇未玻,其他的部分都可以用色值進(jìn)行繪制,當(dāng)然我們?yōu)榱朔奖愫兀瓦B底部框一起切了扳剿;
先從gif 圖里把飛動(dòng)的小葉子和右邊旋轉(zhuǎn)的風(fēng)扇、底部框摳出來昼激,小葉子圖如下:
我們需要處理的主要有兩個(gè)部分:
- 隨著進(jìn)度往前繪制的進(jìn)度條庇绽;
- 不斷飛出來的小葉片;
我們先處理第一部分 - 隨著進(jìn)度往前繪制的進(jìn)度條:
進(jìn)度條的位置根據(jù)外層傳入的 progress 進(jìn)行計(jì)算橙困,可以分為圖中 1瞧掺、2、3 三個(gè)階段:
- 當(dāng)progress 較小凡傅,算出的當(dāng)前距離還在弧形以內(nèi)時(shí)辟狈,需要繪制如圖所示 1 區(qū)域的弧形,其余部分用白色填充夏跷;
- 當(dāng) progress 算出的距離到2時(shí)哼转,需要繪制棕色半圓弧形,其余部分用白色矩形填充拓春;
- 當(dāng) progress 算出的距離到3 時(shí)释簿,需要繪制棕色半圓弧形,棕色矩形硼莽,白色矩形;
- 當(dāng) progress 算出的距離到頭時(shí),需要繪制棕色半圓弧形懂鸵,棕色矩形偏螺;(可以合并到3中)
首先根據(jù)進(jìn)度條的寬度和當(dāng)前進(jìn)度、總進(jìn)度算出當(dāng)前的位置:
//mProgressWidth為進(jìn)度條的寬度匆光,根據(jù)當(dāng)前進(jìn)度算出進(jìn)度條的位置
mCurrentProgressPosition = mProgressWidth * mProgress / TOTAL_PROGRESS;
然后按照上面的邏輯進(jìn)行繪制套像,其中需要計(jì)算上圖中的紅色弧角角度,計(jì)算方法如下:
// 單邊角度
int angle = (int) Math.toDegrees(Math.acos((mArcRadius - mCurrentProgressPosition)/ (float) mArcRadius));
-
Math.acos()
-反余弦函數(shù)终息; -
Math.toDegrees()
- 弧度轉(zhuǎn)化為角度夺巩,Math.toRadians 角度轉(zhuǎn)化為弧度。
所以圓弧的起始點(diǎn)為:
int startAngle = 180 - angle;
圓弧劃過的角度為:
2 * angle
這一塊的代碼如下:
// mProgressWidth為進(jìn)度條的寬度周崭,根據(jù)當(dāng)前進(jìn)度算出進(jìn)度條的位置
mCurrentProgressPosition = mProgressWidth * mProgress / TOTAL_PROGRESS;
// 即當(dāng)前位置在圖中所示1范圍內(nèi)
if (mCurrentProgressPosition < mArcRadius) {
Log.i(TAG, "mProgress = " + mProgress + "---mCurrentProgressPosition = "
+ mCurrentProgressPosition
+ "--mArcProgressWidth" + mArcRadius);
// 1.繪制白色ARC柳譬,繪制orange ARC
// 2.繪制白色矩形
// 1.繪制白色ARC
canvas.drawArc(mArcRectF, 90, 180, false, mWhitePaint);
// 2.繪制白色矩形
mWhiteRectF.left = mArcRightLocation;
canvas.drawRect(mWhiteRectF, mWhitePaint);
// 3.繪制棕色 ARC
// 單邊角度
int angle = (int) Math.toDegrees(Math.acos((mArcRadius - mCurrentProgressPosition)
/ (float) mArcRadius));
// 起始的位置
int startAngle = 180 - angle;
// 掃過的角度
int sweepAngle = 2 * angle;
Log.i(TAG, "startAngle = " + startAngle);
canvas.drawArc(mArcRectF, startAngle, sweepAngle, false, mOrangePaint);
} else {
Log.i(TAG, "mProgress = " + mProgress + "---transfer-----mCurrentProgressPosition = "
+ mCurrentProgressPosition
+ "--mArcProgressWidth" + mArcRadius);
// 1.繪制white RECT
// 2.繪制Orange ARC
// 3.繪制orange RECT
// 1.繪制white RECT
mWhiteRectF.left = mCurrentProgressPosition;
canvas.drawRect(mWhiteRectF, mWhitePaint);
// 2.繪制Orange ARC
canvas.drawArc(mArcRectF, 90, 180, false, mOrangePaint);
// 3.繪制orange RECT
mOrangeRectF.left = mArcRightLocation;
mOrangeRectF.right = mCurrentProgressPosition;
canvas.drawRect(mOrangeRectF, mOrangePaint);
}
接下來再來看葉子部分:
首先根據(jù)效果情況基本確定出 曲線函數(shù),標(biāo)準(zhǔn)函數(shù)方程為:y = A(wx+Q)+h续镇,其中w影響周期美澳,A影響振幅 ,周期T= 2 * Math.PI/w;
根據(jù)效果可以看出摸航,周期大致為總進(jìn)度長(zhǎng)度制跟,所以確定w=(float) ((float) 2 * Math.PI /mProgressWidth);
仔細(xì)觀察效果酱虎,我們可以發(fā)現(xiàn)雨膨,葉子飄動(dòng)的過程中振幅不是完全一致的,產(chǎn)生一種錯(cuò)落的效果读串,既然如此聊记,我們給葉子定義一個(gè)Type,根據(jù)Type 確定不同的振幅爹土;
我們創(chuàng)建一個(gè)葉子對(duì)象:
private class Leaf {
// 在繪制部分的位置
float x, y;
// 控制葉子飄動(dòng)的幅度
StartType type;
// 旋轉(zhuǎn)角度
int rotateAngle;
// 旋轉(zhuǎn)方向--0代表順時(shí)針甥雕,1代表逆時(shí)針
int rotateDirection;
// 起始時(shí)間(ms)
long startTime;
}
類型采用枚舉進(jìn)行定義,其實(shí)就是用來區(qū)分不同的振幅:
private enum StartType {
LITTLE, MIDDLE, BIG
}
創(chuàng)建一個(gè)LeafFactory類用于創(chuàng)建一個(gè)或多個(gè)葉子信息:
private class LeafFactory {
private static final int MAX_LEAFS = 6;
Random random = new Random();
// 生成一個(gè)葉子信息
public Leaf generateLeaf() {
Leaf leaf = new Leaf();
int randomType = random.nextInt(3);
// 隨時(shí)類型- 隨機(jī)振幅
StartType type = StartType.MIDDLE;
switch (randomType) {
case 0:
break;
case 1:
type = StartType.LITTLE;
break;
case 2:
type = StartType.BIG;
break;
default:
break;
}
leaf.type = type;
// 隨機(jī)起始的旋轉(zhuǎn)角度
leaf.rotateAngle = random.nextInt(360);
// 隨機(jī)旋轉(zhuǎn)方向(順時(shí)針或逆時(shí)針)
leaf.rotateDirection = random.nextInt(2);
// 為了產(chǎn)生交錯(cuò)的感覺胀茵,讓開始的時(shí)間有一定的隨機(jī)性
mAddTime += random.nextInt((int) (LEAF_FLOAT_TIME * 1.5));
leaf.startTime = System.currentTimeMillis() + mAddTime;
return leaf;
}
// 根據(jù)最大葉子數(shù)產(chǎn)生葉子信息
public List<Leaf> generateLeafs() {
return generateLeafs(MAX_LEAFS);
}
// 根據(jù)傳入的葉子數(shù)量產(chǎn)生葉子信息
public List<Leaf> generateLeafs(int leafSize) {
List<Leaf> leafs = new LinkedList<Leaf>();
for (int i = 0; i < leafSize; i++) {
leafs.add(generateLeaf());
}
return leafs;
}
}
定義兩個(gè)常亮分別記錄中等振幅和之間的振幅差:
// 中等振幅大小
private static final int MIDDLE_AMPLITUDE = 13;
// 不同類型之間的振幅差距
private static final int AMPLITUDE_DISPARITY = 5;
// 中等振幅大小
private int mMiddleAmplitude = MIDDLE_AMPLITUDE;
// 振幅差
private int mAmplitudeDisparity = AMPLITUDE_DISPARITY;
有了以上信息社露,我們則可以獲取到葉子的Y值:
// 通過葉子信息獲取當(dāng)前葉子的Y值
private int getLocationY(Leaf leaf) {
// y = A(wx+Q)+h
float w = (float) ((float) 2 * Math.PI / mProgressWidth);
float a = mMiddleAmplitude;
switch (leaf.type) {
case LITTLE:
// 小振幅 = 中等振幅 - 振幅差
a = mMiddleAmplitude - mAmplitudeDisparity;
break;
case MIDDLE:
a = mMiddleAmplitude;
break;
case BIG:
// 小振幅 = 中等振幅 + 振幅差
a = mMiddleAmplitude + mAmplitudeDisparity;
break;
default:
break;
}
Log.i(TAG, "---a = " + a + "---w = " + w + "--leaf.x = " + leaf.x);
return (int) (a * Math.sin(w * leaf.x)) + mArcRadius * 2 / 3;
}
接下來,我們開始繪制葉子:
/**
* 繪制葉子
*
* @param canvas
*/
private void drawLeafs(Canvas canvas) {
long currentTime = System.currentTimeMillis();
for (int i = 0; i < mLeafInfos.size(); i++) {
Leaf leaf = mLeafInfos.get(i);
if (currentTime > leaf.startTime && leaf.startTime != 0) {
// 繪制葉子--根據(jù)葉子的類型和當(dāng)前時(shí)間得出葉子的(x琼娘,y)
getLeafLocation(leaf, currentTime);
// 根據(jù)時(shí)間計(jì)算旋轉(zhuǎn)角度
canvas.save();
// 通過Matrix控制葉子旋轉(zhuǎn)
Matrix matrix = new Matrix();
float transX = mLeftMargin + leaf.x;
float transY = mLeftMargin + leaf.y;
Log.i(TAG, "left.x = " + leaf.x + "--leaf.y=" + leaf.y);
matrix.postTranslate(transX, transY);
// 通過時(shí)間關(guān)聯(lián)旋轉(zhuǎn)角度峭弟,則可以直接通過修改LEAF_ROTATE_TIME調(diào)節(jié)葉子旋轉(zhuǎn)快慢
float rotateFraction = ((currentTime - leaf.startTime) % LEAF_ROTATE_TIME)
/ (float) LEAF_ROTATE_TIME;
int angle = (int) (rotateFraction * 360);
// 根據(jù)葉子旋轉(zhuǎn)方向確定葉子旋轉(zhuǎn)角度
int rotate = leaf.rotateDirection == 0 ? angle + leaf.rotateAngle : -angle
+ leaf.rotateAngle;
matrix.postRotate(rotate, transX
+ mLeafWidth / 2, transY + mLeafHeight / 2);
canvas.drawBitmap(mLeafBitmap, matrix, mBitmapPaint);
canvas.restore();
} else {
continue;
}
}
}
最后,向外層暴露幾個(gè)接口:
/**
* 設(shè)置中等振幅
*
* @param amplitude
*/
public void setMiddleAmplitude(int amplitude) {
this.mMiddleAmplitude = amplitude;
}
/**
* 設(shè)置振幅差
*
* @param disparity
*/
public void setMplitudeDisparity(int disparity) {
this.mAmplitudeDisparity = disparity;
}
/**
* 獲取中等振幅
*
* @param amplitude
*/
public int getMiddleAmplitude() {
return mMiddleAmplitude;
}
/**
* 獲取振幅差
*
* @param disparity
*/
public int getMplitudeDisparity() {
return mAmplitudeDisparity;
}
/**
* 設(shè)置進(jìn)度
*
* @param progress
*/
public void setProgress(int progress) {
this.mProgress = progress;
postInvalidate();
}
/**
* 設(shè)置葉子飄完一個(gè)周期所花的時(shí)間
*
* @param time
*/
public void setLeafFloatTime(long time) {
this.mLeafFloatTime = time;
}
/**
* 設(shè)置葉子旋轉(zhuǎn)一周所花的時(shí)間
*
* @param time
*/
public void setLeafRotateTime(long time) {
this.mLeafRotateTime = time;
這些接口用來干嘛呢脱拼?用于把我們的動(dòng)效做成完全可手動(dòng)調(diào)節(jié)的瞒瘸,這樣做有什么好處呢?
- 更加便于產(chǎn)品熄浓、射雞濕查看效果情臭,避免YY,自己手動(dòng)調(diào)節(jié),不會(huì)出現(xiàn)要你一遍遍的改參數(shù)安裝俯在、查看竟秫、再改、再查看... ... N遍之后說 “這好像不是我想要的” -- 瞬間天崩地裂跷乐,天昏地暗肥败,感覺被全世界拋棄;
- 便于體現(xiàn)你是一個(gè)考慮全面愕提,思維縝密馒稍,會(huì)編程、會(huì)設(shè)計(jì)的藝術(shù)家浅侨,當(dāng)然這純屬YY纽谒,主要還是方便大家;
如此一來仗颈,射雞濕們只需要不斷的調(diào)節(jié)即可實(shí)時(shí)的看到展現(xiàn)的效果佛舱,最后只需要把最終的參數(shù)反饋過來即可,萬事大吉挨决,一了百了请祖;
當(dāng)然,如果對(duì)方是個(gè)漂亮的妹子脖祈,而你又苦于沒有機(jī)會(huì)搭訕肆捕,以上內(nèi)容就當(dāng)我沒說,盡情的不按要求寫吧盖高,她肯定會(huì)主動(dòng)找你的慎陵,說不定連飯都反過來請(qǐng)了... ...
好啦,言歸正傳喻奥,完成收尾部分席纽,我們讓所有的參數(shù)都可調(diào)節(jié)起來:
