这是特定日期和时间的通话提醒代码。问题是，一旦用户点击提交按钮，就会显示提醒通知。可能是bcoz通知是在系统的时间（模拟器或电话时间）显示的，而不是用户选择的时间和日期。有可能放置＆＃34; timePicked = c.getTimeInMillis（）;＆＃34;或onDateSet（）或onTimeSet（）方法中的问题。任何建议？这对我来说非常重要。

MyBroadcastReceiver alarm = new MyBroadcastReceiver();

答案 0 :(得分：0)
从timepicker对话框中选择时间时设置闹钟。
使用
更新按钮点击代码 btn.setOnClickListener(new View.OnClickListener() {
public void onClick(View v)
{
DialogFragment newFragment = new DatePickerFragment();
newFragment.show(getFragmentManager(),"datePicker");
}
});
在选择时间时开启
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
String am_pm = "";
c= Calendar.getInstance();
c.set(Calendar.HOUR_OF_DAY, hourOfDay);
c.set(Calendar.MINUTE, minute);
timePicked = c.getTimeInMillis();
Log.d("test", "timePicked: " + timePicked);
Log.d("test", "current: " + System.currentTimeMillis() );
if (timePicked != -1) {
MyBroadcastReceiver alarm = new MyBroadcastReceiver();
if(alarm != null) alarm.setOnetimeTimer(MainActivity.this,timePicked);
btn.setText("ALARM SET");
Log.d("test", "ALARM SET!!!");
} else {
//warn the user for ALARM not set?
Log.w("test", "ALARM not SET!!!");
}
}
您也可以取消之前设置的闹钟。
