stickyDots 2 | #####类似QQ的小红点，QQ can drag the little red dot. 3 | 更多介绍[http://blog.csdn.net/mabeijianxi/article/details/50560361](http://blog.csdn.net/mabeijianxi/article/details/50560361) 4 | 5 | 6 | 先看下效果图： 7 | 8 | ![demo](http://7xq6db.com1.z0.glb.clouddn.com/stickydots.gif) 9 | 10 | 11 | [Download Demo](https://github.com/mabeijianxi/stickyDots/blob/master/simple.apk) 12 | 13 | ## Usage 14 | 15 | ###Step-1 16 | 17 | ###Gradle 18 | `dependencies { 19 | compile project(':stickyDotsLib')}` 20 | 21 | --- 22 | ###Step-2 23 | Choose the right place to create it，for example： 24 | 25 | // Note for needed to achieve drag effect of view needs to 26 | 27 | // individually specify a layout file,and layout is best cannot have viewGroup, 28 | 29 | // or view shown above the text may in drag does not recognize. 30 | 31 | // This is in order to facilitate, in order to reduce consumption. 32 | 33 | StickyViewHelper stickyViewHelper = new StickyViewHelper(mContext, viewHolder.mDragView,R.layout.includeview); 34 | 35 | The layout of includeview like this: 36 | 37 | `` 38 | `` 50 | 51 | You can monitor each process of mobile: 52 | 53 | 54 | /** 55 | * view在范围内移动指此此Runnable 56 | * @param viewInRangeMoveRun 57 | */ 58 | public void setViewInRangeMoveRun(Runnable viewInRangeMoveRun) { 59 | this.viewInRangeMoveRun = viewInRangeMoveRun; 60 | } 61 | 62 | /** 63 | * view在范围外移动执行此Runnable 64 | * @param viewOutRangeMoveRun 65 | */ 66 | public void setViewOutRangeMoveRun(Runnable viewOutRangeMoveRun) { 67 | this.viewOutRangeMoveRun = viewOutRangeMoveRun; 68 | } 69 | 70 | /** 71 | * view移出过范围，最后在范围内松手执行次Runnable 72 | * @param viewOut2InRangeUpRun 73 | */ 74 | public void setViewOut2InRangeUpRun(Runnable viewOut2InRangeUpRun) { 75 |

setViewOutRangeUpRun(Runnable viewOutRangeUpRun) { 91 | this.viewOutRangeUpRun = viewOutRangeUpRun; 92 | }` 93 | 94 | You can also specify mapping rules: 95 | 96 | 97 | 98 | /** 99 | * 设置最大拖拽范围 100 | * @param mFarthestDistance px 101 | */ 102 | public void setFarthestDistance(float mFarthestDistance) { 103 | this.mFarthestDistance = mFarthestDistance; 104 | } 105 | 106 | /** 107 | *

126 | public void setmPathColor(int mPathColor) { 127 | this.mPathColor = mPathColor; 128 | }` 129 | 130 | 131 | ##Theory 132 | 133 |

136 | According to the fingers to move the position of the drawing is ok.It need a little geometry knowledge. 137 | 138 | Draw a fixed circle: 139 | `canvas.drawCircle(mFixCanterPoint.x, mFixCanterPoint.y, mFixRadius, 140 | mPaint);` 141 | 142 | Moving to a point of tangency: 143 | `mPath.moveTo(mFixTangentPointes[0].x, mFixTangentPointes[0].y);` 144 | 145 | 146 | According to the two circles tangent point on quadratic bezier curve drawing: 147 | `mPath.quadTo(mCanterPoint.x, mCanterPoint.y, 148 | mDragTangentPoint[0].x, mDragTangentPoint[0].y);` 149 | 150 | Another point of tangency direction to draw a straight line: 151 | ` mPath.lineTo(mDragTangentPoint[1].x, mDragTangentPoint[1].y);` 152 | 153 | Is a quadratic bezier curve: 154 | ` mPath.quadTo(mCanterPoint.x, mCanterPoint.y, 155 | mFixTangentPointes[1].x, mFixTangentPointes[1].y);` 156 | 157 | Form a closed image, in fact, the end connection: 158 | ` mPath.close();` 159 | ` canvas.drawPath(mPath, mPaint);` 160 | 161 | Finally draw drag the circle is complete: 162 | `canvas.drawCircle(mDragCanterPoint.x, mDragCanterPoint.y, 163 | mDragRadius, mPaint);` 164 | 165 | 166 | About the second order bezier curve: 167 | 168 | ![](http://7xq6db.com1.z0.glb.clouddn.com/240px-Bezier_2_big.gif) 169 | 170 | It is the starting point and a form of control points according to certain algorithm 171 | 172 |
