1 | ScaleScrollView
2 | ======
3 | 一个动态Draw的滚动刻度尺。
4 |
5 | 
6 |
7 | Usage
8 | -----
9 | 1. 在xml布局文件中引入:
10 | ```
11 |
21 | ```
22 |
23 | - 目前支持的自定义属性:
24 | * `scale_view_max` 最大值
25 | - `scale_view_min` 最小值
26 | - `scale_view_height` 刻度的高度
27 | - `scale_view_margin` 刻度的间距
28 | - `layout_width` 可动态调整
29 |
30 | - 获取当前的刻度值
31 | ```
32 | scaleScrollView.setOnScrollListener(new OnScrollListener() {
33 | @Override
34 | public void onScaleScroll(int scale) {
35 | mTvHorizontalScale.setText("" + scale);
36 | }
37 | });
38 | ```
39 |
40 | Download
41 | ----
42 | Gradle:
43 | ```
44 | allprojects {
45 | repositories {
46 | ...
47 | maven { url "https://jitpack.io" }
48 | }
49 | }
50 |
51 | dependencies {
52 | compile 'com.github.LichFaker:ScaleView:-SNAPSHOT'
