的Mac OS-X的Android TimePickerDialog - 僅適用一半的時間(直譯)
使用adt
ANDROID
................
問題:當我選擇時間,比如06:00,它將時間設置爲18:00,當我選擇時間18:00時,它將時間設置爲06:00。我似乎無法弄清楚爲什麼。
................
LOGIC
獲取當前日期的實例。
OnClickListener設置爲ButtonImage。
OnClick使用2個參數(一個TextView,當前日期實例)調用showTimeDialog。
TimePicker對話框在設定的時間09:00顯示。
TimeSet設置日曆activeTime的時間和更新一個TextView
..............
追加新的信息
好了,奇怪的事情發生了,現在我的代碼似乎工作,但上次我檢查它是在24:00之前,它的行爲如上所述。它現在有效,現在在英國的時間是00:20。我不知道這是否與它有任何關係,但如果有任何更改,我會更新這篇文章。
額外的新信息2
我的代碼似乎00:00之間的工作 - 它不24:00 - 12:00,但12:00。我難倒..

這裏是我的代碼:
/////// SETUP TIME
// capture our View elements for the start time function
startTimeDisplay = (TextView) findViewById(R.id.editText2);
endTimeDisplay = (TextView) findViewById(R.id.editText3);
startPickTime = (ImageButton) findViewById(R.id.imageButtonStartTime);
endPickTime = (ImageButton) findViewById(R.id.imageButtonEndTime);
// Use the current time as the default values for the time picker
startTime = Calendar.getInstance();
endTime = Calendar.getInstance();
startTime.get(Calendar.DATE);
endTime.get(Calendar.DATE);
// add a click listener to the button
startPickTime.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
showTimeDialog(startTimeDisplay, startTime);
}
});
/* add a click listener to the button */
endPickTime.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
showTimeDialog(endTimeDisplay, endTime);
}
});
}
