一.原生的横向进度条使用方法： 1.布局

2.赋值

private ProgressBar progressBar; progressBar = (ProgressBar) v.findViewById(R.id.pb_update_progress1); progressBar.setProgress(90);

注：使用简单，但颜值太低，所以引入下面颜值高的布局。
二.开源数字进度条控件的配置： Android显示进度数字的进度条，支持动画，支持数字显示，支持颜色搭配自定义等。
效果图：

参考官方说明文档和源码下载：点击进入，仅使用本文提供的代码也可以完整实现，不需要任何Jar包。
1.自定义样式
注：只展示一种，其他样式参见说明文档
style.xml中添加：

name="NumberProgressBar_Default"> wrap_content match_parent 100 0 #CCCCCC @color/bg_blue 10sp #3498DB 1.5dp 0.75dp

提供8种进度条配色样式，效果图：

提供参考，择优使用，在style.xml中替换上述样式或新增即可使用：

name="NumberProgressBar_Default"> wrap_content match_parent100 0#CCCCCC #3498DB10sp #3498DB1.5dp 0.75dpname="NumberProgressBar_Passing_Green"> wrap_content match_parent100 0#CCCCCC #70A80010sp #70A8001.5dp 0.75dpname="NumberProgressBar_Beauty_Red"> wrap_content match_parent100 0#CCCCCC #FF3D7F 10sp #FF3D7F1.5dp 0.75dpname="NumberProgressBar_Warning_Red"> wrap_content match_parent100 0#CCCCCC #E74C3C 10sp #E74C3C1.5dp 0.75dpname="NumberProgressBar_Relax_Blue"> wrap_content match_parent100 0#CCCCCC #6DBCDB 10sp #6DBCDB1.5dp 0.75dpname="NumberProgressBar_Grace_Yellow"> wrap_content match_parent100 0#CCCCCC #FFC73B 10sp #FFC73B1.5dp 0.75dpname="NumberProgressBar_Funny_Orange"> wrap_content match_parent100 0#CCCCCC #FF530D 10sp #FF530D1.5dp 0.75dpname="NumberProgressBar_Twinkle_Night"> wrap_content match_parent100 0#CCCCCC #ECF0F1 10sp #ECF0F11.5dp 0.75dp

2.自定义属性
注：用于在布局中配置样式

3.自定义进度条类：

三.开源数字进度条控件的使用方法： 1.布局：

2.更新进度：

private NumberProgressBar bnp; bnp = (NumberProgressBar)findViewById(R.id.numberbar1); bnp.setProgress(90);
