本文实例分析了android开发之timepicker控件用法。分享给大家供大家参考，具体如下：
新建项目：
new android project->
project name:hellospinner
build target:android 2.2
application name:hellospinner
package name:com.b510
create activity:mainactivity
min sdk version:9
finish
运行效果：
如果：
return new timepickerdialog(this, mtimesetlistener, mhour, mminute, false);
代码部分：
mainactivity.java：
