 1 | 
 2 | # 使用方法
 3 | 1.在项目根目录下的build.gradle中 allprojects repositories 中添加  	maven { url 'https://jitpack.io' } 如下：
 4 | 	allprojects {
 5 | 		repositories {
 6 | 			...
 7 | 			maven { url 'https://jitpack.io' }
 8 | 		}
 9 | 	}
10 |   
11 | 2.在项目中的build.gradle中添加引用
12 | dependencies {
13 | 		 compile 'com.github.chr1123:AndroidWaveView:V1.0.2'
14 | 	}
15 | 
16 | 
17 | 3.在布局文件中使用
18 |    <com.chrischen.waveview.WaveView
19 |         android:id="@+id/waveView"
20 |         android:layout_width="match_parent"
21 |         android:layout_height="100dp"
22 |         android:background="#999"/>
23 |         
24 | 4.代码中使用waveView.putValue(value)为波形图添加采集到的音量值，
25 |   使用setHasOver(true)方法设置停止采集后，若采集点的展示超出了宽度，此时可左右滑动展示
26 | 
27 | 
28 | 
29 | 添加了相关样式设置 ，可设置波形展示方式，线条宽度颜色间距等   如：
30 |   <com.chrischen.waveview.WaveView
31 |         android:id="@+id/waveView"
32 |         android:layout_width="match_parent"
33 |         android:layout_height="100dp"
34 |         android:background="#999"
35 |         app:wvType="centerLine"
36 |         app:wvCenterLineColor="#f0f"
37 |         app:wvCenterLineWidth="1dp"
38 |         app:wvLineColor="#ff0"
39 |         app:wvLineWidth="1dp"
40 |         app:wvLineSpace="5dp"/>
