Android 安卓计时器故障

我试图从我的

TimePicker

小部件中提取所选时间，但是当我使用

getCurrentHour（）

和

getCurrentMinute（）

方法时，它会不断返回当前时间，而不是我选择的时间

                calendar.clear();
            }

        }


    }
}

}

并且选择了与logcat显示的时间不同的时间

有任何修复建议吗？

您应该使用您在回调中返回的时间

你可以看到一个例子

显然，您需要强制它放松焦点，然后更新值

// force the timepicker to loose focus and the typed value is available !
timePicker.clearFocus();
// re-read the values, in my case i put them in a Time object.
time.hour   = timePicker.getCurrentHour();
time.minute = timePicker.getCurrentMinute();

向我们展示你的代码：你是如何设置你的

TimePicker

的，以及你是如何使用它的？我可以直接把它应用到我的java代码中的小部件上吗？我试过这样做：

timePickerOn.setOnTimeChangedListener（new TimePicker.OnTimeChangedListener（）{@Override public void onTimeChanged（TimePicker视图，inthourofday，intminute）{onMins=minute；onHours=hourOfDay；Log.d（“ChangeMins”，String.valueOf（minute））；}}}）；

我刚刚得到了零，因为所选的值仍然是现在的时间。请关闭这个问题：）

// force the timepicker to loose focus and the typed value is available !
timePicker.clearFocus();
// re-read the values, in my case i put them in a Time object.
time.hour   = timePicker.getCurrentHour();
time.minute = timePicker.getCurrentMinute();
