timepicker

问题 I'm using a time picker to let the user enter his desired time to do a specific task, I'm using the DialogFragment class that's available in the support library for backward compatibility with older Android versions. Here is my code to create the TimePickerFragment class, created in a seperate file, taken from: http://developer.android.com/guide/topics/ui/controls/pickers.html : package com.calls.only; import java.util.Calendar; import android.app.Dialog; import android.app.TimePickerDialog;

问题 I want to create a dialog which can select the time and the date at the same time . I know that there is not a default widget that can do that on Android.

问题 I've got a DialogPreference which implements a simple TimePicker.OnTimeChangedListener (see below). Setting the time by clicking the +/- buttons works great. But I don't know how to save the state of the timepicker when the user typed in the time directly into the textfield. It could be sufficient to access to the current textfield value, so I'd be able to persist it in onDialogClosed. But timePicker.getCurrentHour() won't do it. Please help... public class TimePreference extends

问题 My view has a white background, and it has to stay that way. I have a TimePicker on that white background.Everything is woking fine with android 2.3.3 but android 4.0.3 has a new timePicker style. The numbers have a very bright color. It is very hard to see them on the white background, and I didn't find a direct way to change the textColor. I don't want to change the background because it would look not so good. Is there any way to override this and set the color of the numbers to black?

问题 I have a TimePickerDialog with is24Hour set to false since I want to present the end-user with the more familiar 12 hour format. When the hour, minute and AM PM indicator are set and the time is returned how can I identify whether the end-user has selected AM or PM? This is what I have for the listener: private TimePickerDialog.OnTimeSetListener mTimeSetListener = new TimePickerDialog.OnTimeSetListener() { @Override public void onTimeSet(TimePicker view, int hourOfDay, int minute) { mHour =

问题 What i want: the buttons text is "08:00" now. When click the button it shows a timepicker. The selected time is set to the buttons text. (Alarm app). i have read some tutorials and questions-answers about this, but haven't find the answers yet. After i press the clock button the app crashes. If i put the onCreateView part in comment it works. it says: android.util.AndroidRuntimeException: requestFeature() must be called before adding content. public class TimeSet extends DialogFragment

问题 I am trying to use a Datepicker + a Timepicker together to return a DateTime that can be stored in a database.
