前言

项目中又语音录入文字的功能,需要一个动画效果。所以需要时间一个随音频大小而改变的波浪。是基于A memory-friendly recording wave animation一款性能内存友好的录音波浪动画的基础上进行修改完成的。感谢这位大神,原理讲解请看这里

看一下效果图:

使用方式:

Step 1. Add it in your root build.gradle at the end of repositories:
    allprojects { 
		repositories {
			...
			maven { url 'https://jitpack.io' }
		}
	}
Step 2. Add the dependency
	dependencies {
	        implementation 'com.github.lzy2626:WaveLine:1.0'
	}
Step 3.xml
    <com.lzy.waveline.WaveLineView
        android:id="@+id/waveLineView"
        android:layout_width="match_parent"
        android:layout_height="200dp"
        app:wlvBackgroundColor="@android:color/white" />
Step 4.activity
  waveLineView = (WaveLineView) findViewById(R.id.waveLineView);
  waveLineView.startAnim();

//根据声音大小进行设置
 waveLineView.setVolume((int) db);
