安卓TimePicker AM / PM按钮不调用onTimeChanged [英] Android TimePicker AM/PM button not invoking onTimeChanged

问题描述

我在实现我的应用程序中的TimePicker，它允许用户在一个数据库记录的时间而改变其插入之前的一些问题。

现在的问题是，当AM / PM按钮是pressed的onTimeChanged（查看，INT，INT）方法不会被调用。每当我改变任何一个小时或TimePicker的分值，onTimeChanged（）被调用，但是。

方案：

• 用户只要点击了AM / PM按钮：AM / PM是不会更新
• 在用户点击时/分：时间被更新
• 在用户点击则AM / PM按钮可改变时/分：时间和AM / PM更新

我错在以为AM / PM按钮应该能够被点击更新时间而不具有AM / PM按钮后，也会改变一个时间值？

我已经把一个小的测试项目中复制此而这里的code：

活动

 公共类TestActivity扩展活动实现OnTimeChangedListener {

    私人日历mCalendar;

    @覆盖
    保护无效的onCreate（包savedInstanceState）{
        super.onCreate（savedInstanceState）;
        的setContentView（R.layout.timepicker）;

        mCalendar = Calendar.getInstance（）;

        TimePicker TP =（TimePicker）findViewById（R.id.timepicker）;
        tp.setIs24HourView（假）;
        tp.setOnTimeChangedListener（本）;
    }

    @覆盖
    公共无效onTimeChanged（TimePicker观点，诠释hourOfDay，INT分钟）{
        Log.d（TAG，在onTimeChanged）;
        mCalendar.set（mCalendar.get（Calendar.YEAR）
                      mCalendar.get（Calendar.MONTH）
                      mCalendar.get（Calendar.DAY_OF_MONTH）
                      hourOfDay，
                      分钟）;

        setCalendarTime（）;
    }

    私人无效setCalendarTime（）{
        日期日期= mCalendar.getTime（）;

        如果（日期！= NULL）{
            SimpleDateFormat的格式化=新的SimpleDateFormat（MM / DD / YY'@'H：毫米）;
            字符串日期时间= formatter.format（日期）;

            Toast.makeText（本，日期时间，Toast.LENGTH_LONG）.show（）;
        }
    }
}

解决方案

我已经测试code。是的，你说得对，TimePicker AM / PM按钮不调用onTimeChanged方法，它应该。

其实，它是一个错误。据报道，以谷歌。你可以在这里

I'm having some issues implementing a TimePicker in my application that allows the user to change the time of a database record prior to inserting it.

The problem is that when the AM/PM button is pressed, the onTimeChanged(View, int, int) method isn't invoked. Whenever I change either the hour or minute value of the TimePicker, onTimeChanged() is called, however.

Scenarios:

• User just clicks the AM/PM button: AM/PM is NOT updated
• User clicks the Hours/Minutes: Time is updated
• User clicks the AM/PM button then changes the hours/minutes: Time and AM/PM is updated

Am I wrong in thinking that the AM/PM button should be able to be clicked to update the time without having to also change a time value after the am/pm button?

I've put together a small test project to replicate this and here's the code:

Activity

public class TestActivity extends Activity implements OnTimeChangedListener {

    private Calendar mCalendar;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.timepicker);

        mCalendar = Calendar.getInstance();

        TimePicker tp = (TimePicker)findViewById(R.id.timepicker);
        tp.setIs24HourView(false);
        tp.setOnTimeChangedListener(this);
    }

    @Override
    public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
        Log.d("TAG", "In onTimeChanged");
        mCalendar.set(mCalendar.get(Calendar.YEAR),
                      mCalendar.get(Calendar.MONTH),
                      mCalendar.get(Calendar.DAY_OF_MONTH),
                      hourOfDay,
                      minute);

        setCalendarTime();
    }

    private void setCalendarTime() {
        Date date = mCalendar.getTime();

        if (date != null) {
            SimpleDateFormat formatter = new SimpleDateFormat("MM/dd/yy '@' h:mm a");
            String dateTime = formatter.format(date);

            Toast.makeText(this, dateTime, Toast.LENGTH_LONG).show();
        }
    }
}

timepicker.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:layout_width="fill_parent"
              android:layout_height="fill_parent"
              android:fillViewport="true">
    <TimePicker android:id="@+id/timepicker"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:layout_marginLeft="5dip"
                android:layout_marginRight="5dip"/>
</LinearLayout>

解决方案

I have tested the code. Yes, you are right, TimePicker AM/PM button not invoking onTimeChanged method which it should.

Actually, Its a bug. It has been reported to google. You can find it here
