android– 如何使用报警管理器区分上午和下午之间的报警？

概述我正在为约会提醒我创建警报提醒我正在使用以下代码.代码工作得非常好,它向我显示警报提醒,但唯一的问题是,它不区分上午和下午之间的警报,假设我设置警报为上午7点和当前晚上7点在设备中,然后我的警报对话框显示.我怎样才能管理上午和下午？我用这个链接来参考http://wptrafficanal

DemoActivity.class

public class DemoActivity extends FragmentActivity {@OverrIDeprotected voID onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    /** Creating an Alert Dialog Window */    AlertDemo alert = new AlertDemo();    /** opening the Alert Dialog Window */    alert.show(getSupportFragmentManager(), "AlertDemo");}}

解决方法:

您没有处理AM / PM.只要把这些代码行……

int timeDifference=0; String ampm=splitampmtime[1]; if(ampm.matches("PM")){ timeDifference=12; } int splithour = timeDifference+Integer.parseInt(splitstrtime[0]); String[] splitsecond = splitstrtime[1].split(" ");
