Android 声纹进度播放效果(自定义View)
Android 声纹进度播放效果(自定义View)
描述:这是一个 声纹进度播放效果的Demo。
项目代码在最后面!!!!跳转到最后
控件效果如下:
实现功能:
- 声纹可随机显示也可固定
- 可自定义加载前后两种颜色
设计核心:
主要的设计核心是依赖于drawRoundRect方法进行声纹条形的绘制。
核心代码:
VoiceProgressView.java 一个声纹进度播放的自定义View 可直接载入layout
import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.util.AttributeSet;
import android.view.View;
import java.security.SecureRandom;
import java.util.ArrayList;
import java.util.List;
