在工作中难免遇到自定义 `View` 的相关需求，本身这方面比较薄弱，因此做个记录，也是自己学习和成长的积累。[自定义View实战](https://link.jianshu.com/?t=http%3A%2F%2Fxiaweizi.cn%2Fcategories%2F%25E8%2587%25AA%25E5%25AE%259A%25E4%25B9%2589View%25E5%25AE%259E%25E6%2588%2598%2F) 2 | 3 | ## 前言 4 | 5 | 最近项目需要接入环信客服 `SDK` ，我配合这同事完成，其中我负责文件下载这部分。 6 | 7 | 因为时间比较紧张，8 天的时间完成 **环信客服模块** 的接入，就直接用了环信提供的 `UI` 控件，但是一些细节的部分， `UI` 还是会给出设计图，按照设计图完成最终效果。 8 | 9 | `UI`那边直接让我参考 `IOS`的实现效果: 10 | 11 | ![UI效果](http://upload-images.jianshu.io/upload_images/4043475-ee6d3767cc22230c..png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240) 12 | 13 | ## 最终效果 14 | 15 | ![最终效果](http://upload-images.jianshu.io/upload_images/4043475-d1f9ca5534094c84..gif?imageMogr2/auto-orient/strip) 16 | 17 | 源码请看 [DownloadLoadingView](https://github.com/xiaweizi/DownloadLoadingView) 18 | 19 | ## 功能分析 20 | 21 | 面对这样的需要应该怎么实现呢？其实实现的方式可能不止我想的这种，我就讲述一下我是如何处理的。 22 | 23 | ![预览图](http://upload-images.jianshu.io/upload_images/4043475-52fe9c8f5f078c8a..png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240) 24 | 25 | 首先，可以分成三部分： 26 | 27 | 1. 半透明的背景 28 | 2. 全透明的环 29 | 3. 实心全透明的弧 30 | 31 | 那怎么实现背景半透明，而圆环和弧又是全透明的。顿时有个想法，要是两张图片重叠的部分能被抠出掉，也就是变成全透明，那岂不是非常容易就实现了。 32 | 33 | 圆环和弧既然是盖在了背景上，理当直接变成透明。那 `Android` 有对应处理的 `API`吗？答案是肯定的。 **setXfermode()** 用于设置图像的过度模式，其中 **PorterDuff.Mode.CLEAR** 为清除模式则可以实现上述的效果。 34 | 35 | ## 具体实现 36 | 37 | ### 一系列的初始化 38 | 39 | ```java 40 | public DownloadLoadingView(Context context, AttributeSet attrs) { 41 | super(context, attrs); 42 | TypedArray typedArray = context.obtainStyledAttributes(attrs, R.styleable.DownloadLoadingView); 43 | mRadius = typedArray.getDimension(R.styleable.DownloadLoadingView_radius, RADIUS_DEFAULT); 44 | mStrokeWidth = typedArray.getDimension(R.styleable.DownloadLoadingView_strokeWidth, STROKE_WIDTH_DEFAULT); 45 | mMaxProgress = typedArray.getInteger(R.styleable.DownloadLoadingView_maxProgress, MAX_PROGRESS_DEFAULT); 46 | mRoundRadius = typedArray.getDimension(R.styleable.DownloadLoadingView_roundRadius, ROUND_RADIUS_DEFAULT); 47 | mBackgroundColor = typedArray.getColor(R.styleable.DownloadLoadingView_backgroundColor, getResources().getColor(R.color.bg_default)); 48 | Log.i(TAG, "radius:" + mRadius); 49 | typedArray.recycle(); 50 | setLayerType(View.LAYER_TYPE_SOFTWARE, null);//关闭硬件加速 51 | paint = new Paint(Paint.ANTI_ALIAS_FLAG); 52 | } 53 | ``` 54 | 55 | > 记得需要关闭硬件加速，不然会没有效果。 56 | 57 | ### 绘制背景 58 | 59 | ```java 60 | paint.setColor(mBackgroundColor); 61 | paint.setStyle(Paint.Style.FILL); 62 | RectF round = new RectF(0, 0, getWidth(), getHeight()); 63 | canvas.drawRoundRect(round, mRoundRadius, mRoundRadius, paint); 64 | ``` 65 | 66 | > 设置背景颜色，样式为填充，绘制圆角矩形 67 | 68 | ### 绘制圆环 69 | 70 | ```java 71 | paint.setColor(Color.RED); 72 | paint.setStrokeWidth(mStrokeWidth); 73 | // 采用 clear 的方式 74 | paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.CLEAR)); 75 | paint.setStyle(Paint.Style.STROKE); 76 | canvas.drawCircle(getWidth() / 2, getHeight() / 2, mRadius, paint); 77 | ``` 78 | 79 | > 圆环的颜色可以随意设置，毕竟最后会被抠除掉， 80 | > 81 | > 设置 `PorterDuff.Mode.CLEAR` 类型模式绘制圆环 82 | 83 | ### 绘制圆 84 | 85 | ```java 86 | paint.setStyle(Paint.Style.FILL); 87 | float sweepAngle = 360 * mProgress / mMaxProgress; 88 | RectF rectF = new RectF(getWidth() / 2 - mRadius, getHeight() / 2 - mRadius, getWidth() / 2 + mRadius, getHeight() / 2 + mRadius); 89 | canvas.drawArc(rectF, -90, sweepAngle, true, paint); 90 | // 记得设置为 null 不然会没有效果 91 | paint.setXfermode(null); 92 | ``` 93 | 94 | > 根据当前的进度绘制相对应的弧，并且结束的时候将 `Xfermode` 模式置为 `null`。 95 | 96 | 这样效果就结束了，贼简单。完整的代码请看 [DownloadLoadingView](https://github.com/xiaweizi/DownloadLoadingView) 97 | 98 | ## 拓展 99 | 100 | 文中提到了 `PorterDuff.Mode`，里面存储了大量的枚举，当我们需要处理图像的时候就会用到，但是对每种类型并没有特别的了解。每次使用的时候都需要查资料，然后确定到底需要使用哪种模式。 101 | 102 | ```java 103 | public Xfermode setXfermode(Xfermode xfermode) { 104 | long xfermodeNative = 0; 105 | if (xfermode != null) 106 | xfermodeNative = xfermode.native_instance; 107 | native_setXfermode(mNativePaint, xfermodeNative); 108 | mXfermode = xfermode; 109 | return xfermode;。 110 | } 111 | ``` 112 | 113 | 具体的模式： 114 | 115 | ```java 116 | public enum Mode { 117 | /** [0, 0] */ 118 | CLEAR (0), 119 | /** [Sa, Sc] */ 120 | SRC (1), 121 | /** [Da, Dc] */ 122 | DST (2), 123 | /** [Sa + (1 - Sa)*Da, Rc = Sc + (1 - Sa)*Dc] */ 124 | SRC_OVER (3), 125 | /** [Sa + (1 - Sa)*Da, Rc = Dc + (1 - Da)*Sc] */ 126 | DST_OVER (4), 127 | /** [Sa * Da, Sc * Da] */ 128 | SRC_IN (5), 129 | /** [Sa * Da, Sa * Dc] */ 130 | DST_IN (6), 131 | /** [Sa * (1 - Da), Sc * (1 - Da)] */ 132 | SRC_OUT (7), 133 | /** [Da * (1 - Sa), Dc * (1 - Sa)] */ 134 | DST_OUT (8), 135 | /** [Da, Sc * Da + (1 - Sa) * Dc] */ 136 | SRC_ATOP (9), 137 | /** [Sa, Sa * Dc + Sc * (1 - Da)] */ 138 | DST_ATOP (10), 139 | /** [Sa + Da - 2 * Sa * Da, Sc * (1 - Da) + (1 - Sa) * Dc] */ 140 | XOR (11), 141 | /** [Sa + Da - Sa*Da, Sc*(1 - Da) + Dc*(1 - Sa) + min(Sc, Dc)] */ 142 | DARKEN (12), 143 | /** [Sa + Da - Sa*Da, Sc*(1 - Da) + Dc*(1 - Sa) + max(Sc, Dc)] */ 144 | LIGHTEN (13), 145 | /** [Sa * Da, Sc * Dc] */ 146 | MULTIPLY (14), 147 | /** [Sa + Da - Sa * Da, Sc + Dc - Sc * Dc] */ 148 | SCREEN (15), 149 | /** Saturate(S + D) */ 150 | ADD (16), 151 | OVERLAY (17); 152 | Mode(int nativeInt) { 153 | this.nativeInt = nativeInt; 154 | } 155 | /** 156 | * @hide 157 | */ 158 | public final int nativeInt; 159 | } 160 | ``` 161 | 162 | 注释中已经说明了该模式到的透明度计算和颜色的计算方式，首先我们要了解一下基本的概念： 163 | 164 | ```js 165 | Sa：全称为Source alpha，表示源图的Alpha通道； 166 | Sc：全称为Source color，表示源图的颜色； 167 | Da：全称为Destination alpha，表示目标图的Alpha通道； 168 | Dc：全称为Destination color，表示目标图的颜色. 169 | ``` 170 | 171 | 来看一下权威的展示图： 172 | 173 |
