QQ群头像以及微信讨论组头像工具类介绍
介绍:
由于段时间公司项目需求,在翻了网上很多代码后发现,很多人用的是自定义View的办法来实现此类头像的效果,但是,这样一来就必须改变项目中原有的控件,而且当需要将此图片内容传递到后台时,就会变的非常麻烦,所以我就从网上找了一个Demo来自己修改,将其变成了一个可以直接生成一张头像图片的工具类,这样一来无论你需要什么样的操作都会非常方便,可以将这张生成的图片随意设置,下面放几张项目的图片给各位看一下:
下面是微信的讨论组头像展示:
主要是用到了三个类:
这里的JoinBitmaps主要是底层对该图片的一些剪裁等处理,JoinLayout是对头像中具体图片绘制时的参数进行设置,所以,这两个类其实是网上找的牛人写好的,TaolunBitmapUtils则是我对一些具体方法的封装,下面将贴出具体代码内容:
public class JoinBitmaps {public static final void join(Canvas canvas, int dimension, List<Bitmap> bitmaps) {if (bitmaps == null)return;int count = Math.min(bitmaps.size(), JoinLayout.max());float[] size = JoinLayout.size(count);join(canvas, dimension, bitmaps, count, size);}public static final void join(Canvas canvas, int dimension, List<Bitmap> bitmaps, int count,float[] size) {join(canvas, dimension, bitmaps, count, size, 0.15f);}public static final void join(Canvas canvas, int dimension, List<Bitmap> bitmaps,float gapSize) {if (bitmaps == null)return;int count = Math.min(bitmaps.size(), JoinLayout.max());float[] size = JoinLayout.size(count);join(canvas, dimension, bitmaps, count, size, gapSize);}public static final void join(Canvas canvas, int dimension, List<Bitmap> bitmaps, int count,float[] size, float gapSize) {if (bitmaps == null)return;// 旋转角度float[] rotation = JoinLayout.rotation(count);// paintPaint paint = new Paint();paint.setAntiAlias(true);Matrix matrixJoin = new Matrix();// scale as join sizematrixJoin.postScale(size[0], size[0]);canvas.save();// canvas.drawColor(Color.RED);// index<count bitmaps.size 可能会越界for (int index = 0; index < count; index++) {Bitmap bitmap = bitmaps.get(index);// MATRIXMatrix matrix = new Matrix();// scale as destinationmatrix.postScale((float) dimension / bitmap.getWidth(),(float) dimension / bitmap.getHeight());canvas.save();matrix.postConcat(matrixJoin);float[] offset = JoinLayout.offset(count, index, dimension, size);canvas.translate(offset[0], offset[1]);// 缩放Bitmap newBitmap = Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(),bitmap.getHeight(), matrix, true);// 裁剪Bitmap bitmapOk = createMaskBitmap(newBitmap, newBitmap.getWidth(),newBitmap.getHeight(), (int) rotation[index], gapSize);canvas.drawBitmap(bitmapOk, 0, 0, paint);canvas.restore();}canvas.restore();}public static final Bitmap createMaskBitmap(Bitmap bitmap, int viewBoxW, int viewBoxH,int rotation, float gapSize) {Bitmap output = Bitmap.createBitmap(bitmap.getWidth(), bitmap.getHeight(),Bitmap.Config.ARGB_8888);Canvas canvas = new Canvas(output);final Paint paint = new Paint();paint.setAntiAlias(true);// 抗锯齿paint.setFilterBitmap(true);int center = Math.round(viewBoxW / 2f);canvas.drawCircle(center, center, center, paint);paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));canvas.drawBitmap(bitmap, 0, 0, paint);if (rotation != 360) {Matrix matrix = new Matrix();// 根据原图的中心位置旋转matrix.setRotate(rotation, viewBoxW / 2, viewBoxH / 2);canvas.setMatrix(matrix);paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.CLEAR));canvas.drawCircle(viewBoxW * (1.5f - gapSize), center, center, paint);}return output;}public static final Bitmap createBitmap(int width, int height, List<Bitmap> bitmaps) {int count = Math.min(bitmaps.size(), JoinLayout.max());float[] size = JoinLayout.size(count);return createBitmap(width, height, bitmaps, count, size, 0.15f);}public static final Bitmap createBitmap(int width, int height, List<Bitmap> bitmaps,int count, float[] size) {return createBitmap(width, height, bitmaps, count, size, 0.15f);}public static final Bitmap createBitmap(int width, int height, List<Bitmap> bitmaps,int count, float[] size, float gapSize) {Bitmap output = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);Canvas canvas = new Canvas(output);int dimen = Math.min(width, height);join(canvas, dimen, bitmaps, count, size, gapSize);return output;}}

使用:
当然,最后免不了讲一下使用的步骤:
1.将这三个工具类放到自己项目的文件夹下面;
2.在需要的地方调用相应的方法来生成一张Bitmap;
2.1qq群头像使用示例:
private ImageView[] name =new ImageView[id.length];private List<Bitmap> qq = new ArrayList<>();//作为QQ群头像的数据源
//QQ3个头像Bitmap bitmap4 = BitmapFactory.decodeResource(getResources(),R.mipmap.a1);Bitmap bitmap5 = BitmapFactory.decodeResource(getResources(),R.mipmap.a2);Bitmap bitmap6 = BitmapFactory.decodeResource(getResources(),R.mipmap.a3);qq.clear();qq.add(bitmap4);qq.add(bitmap5);qq.add(bitmap6);Bitmap data2 = TaolunBitmapUtils.CircleTaolunBitmap(150,150,qq);name[2].setImageBitmap(data2);//改变头像背景Bitmap datas2 = TaolunBitmapUtils.CircleTaolunBitmap(150,150,qq, Color.parseColor("#cc805f"));name[7].setImageBitmap(datas2);
这里是生成一张具有三个头像的图片例子,这里需要特别注意的是,TaolunBitmapUtils这个类中所有的方法都是需要给一个Bitmap类型的List集合,之后,相应的方法中会自动将集合里面的Bitmap取出来制作成一张头像图片。例如,这里的CircleTaolunBitmap()方法中的最后一个参数qq就是已经写好的Bitmap集合,最终返回的这张Bitmap就是你所需要的图片了,在这里我将它放在了ImageView上面,至于下面的4个参数的CircleTaolunBitmap()中最后一个参数是设置的整个图片的背景色,需要的可以在这里自由设置。
2.2微信讨论组头像使用示例
private ImageView[] name =new ImageView[id.length];private List<Bitmap> wx = new ArrayList<>();//作为微信讨论组头像的数据源
Bitmap bitmap91 = BitmapFactory.decodeResource(getResources(),R.mipmap.a1);Bitmap bitmap92 = BitmapFactory.decodeResource(getResources(),R.mipmap.a2);Bitmap bitmap93 = BitmapFactory.decodeResource(getResources(),R.mipmap.a3);Bitmap bitmap94 = BitmapFactory.decodeResource(getResources(),R.mipmap.a4);Bitmap bitmap95 = BitmapFactory.decodeResource(getResources(),R.mipmap.a5);Bitmap bitmap96 = BitmapFactory.decodeResource(getResources(),R.mipmap.a6);Bitmap bitmap97 = BitmapFactory.decodeResource(getResources(),R.mipmap.a1);Bitmap bitmap98 = BitmapFactory.decodeResource(getResources(),R.mipmap.a2);Bitmap bitmap99 = BitmapFactory.decodeResource(getResources(),R.mipmap.a3);wx.clear();wx.add(bitmap91);wx.add(bitmap92);wx.add(bitmap93);wx.add(bitmap94);wx.add(bitmap95);wx.add(bitmap96);wx.add(bitmap97);wx.add(bitmap98);wx.add(bitmap99);Bitmap data9 = TaolunBitmapUtils.SquareTaolunzuBitmap(this,170,170,wx);name[2].setImageBitmap(data9);//改变头像背景Bitmap datas9 = TaolunBitmapUtils.SquareTaolunzuBitmap(this,170,170,wx, Color.parseColor("#a45d97"));name[5].setImageBitmap(datas9);
这里是设置微信头像的例子,原理还是跟上面一样,主要调用的是SquareTaolunzuBitmap()这个方法了,第一个参数环境变量,第二三个参数分别是宽跟高,最后一个参数同样是Bitmap类型的List集合,倒数第二行的代码中,多的那一个参数也是对背景颜色的设置,供给这方面有所需要的童鞋们使用。
总结:
基本的介绍就到这里为止了,如果还有不明白的地方可以参考下面的链接中的Demo,里面我都尽可能详细地加了很多注解,而且,三个页面都是最简单的方式进行呈现的,或者还可以私信我,虽然不常常上线,但是在看到的时候会尽快回复的。
最后,如果哪里还有不好的地方请各位及时指出,我也会尽力改正的!
