Question

我有一个布局，我在其中放置了一个TimePicker和两个用于选择时间的按钮：

    <?xml version="1.0" encoding="utf-8"?>

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:layout_width="fill_parent"
              android:layout_height="fill_parent"
              android:orientation="vertical"
        >
    <TimePicker android:id="@+id/time_picker"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
        />
    <LinearLayout android:layout_width="fill_parent"
              android:layout_height="fill_parent"
              android:orientation="horizontal"
        >
    <Button android:id="@+id/time_picker_ok"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="@string/yes"
            android:onClick="set"/>
    <Button android:id="@+id/time_picker_cancel"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="@string/no"
            android:onClick="cancel"/>
    </LinearLayout>
    </LinearLayout>

我通过其他活动的方法调用它：

public void showPicker(View view) {
    LayoutInflater li = LayoutInflater.from(this);
    View dialogView = li.inflate(R.layout.time_picker, null);
    dialogView = new TimePicker(this);

    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle(R.string.time_start_label);
    builder.setView(dialogView);

    ad = builder.create();
    ad.show();
}

我有一个“是”按钮的处理程序：

public void set(View view) {
    LayoutInflater li = LayoutInflater.from(this);
    LinearLayout ll = (LinearLayout) li.inflate(R.layout.time_picker, null);
    TimePicker tp = (TimePicker) ll.findViewById(R.id.time_picker);
    int hour = tp.getCurrentHour();
    int minute = tp.getCurrentMinute();

    Utils.showMessage(this, hour + " " + minute); // Toast message
}

但是当我点击@ + id / time_picker_ok时，我得到的是当前的系统时间而不是选定的时间。

我如何获得选定的时间？

Answer 1

getCurrentXXX（）应该回答当前的小时或分钟。

要读取用户输入的时间，您必须使用如下监听器：

// the callback received when the user "sets" the time in the dialog
private TimePickerDialog.OnTimeSetListener mTimeSetListener =
    new TimePickerDialog.OnTimeSetListener() {
        public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
            mHour = hourOfDay;
            mMinute = minute;
            updateDisplay();
        }
    };

从DatePicker获取日期和时间的简单方法TimePicker

警告：它使用 JodaTime的 DateTime作为回报。您可以修改它以使用您喜欢的任何内容。

 // Gets the Date and Time from a DatePicker and TimePicker and return a JodaTime DateTime from them, in current timezone.
 //
 private DateTime getDateTimeFromPickers( int DatePickerId, int TimePickerId ) {
     DatePicker dp = (DatePicker) findViewById(DatePickerId);
     TimePicker tp = (TimePicker) findViewById(TimePickerId);

     String year    = Integer.toString(dp.getYear()) ;
     String month   = StringUtils.leftPad( Integer.toString(dp.getMonth() + 1), 2, "0" );
     String day     = StringUtils.leftPad( Integer.toString(dp.getDayOfMonth()), 2, "0" );
     String hour    = StringUtils.leftPad( Integer.toString(tp.getCurrentHour()), 2, "0" );
     String minutes = StringUtils.leftPad( Integer.toString(tp.getCurrentMinute()), 2, "0" );

     String dateTime = year + "-" + month + "-" + day + "T" + hour + ":" + minutes + ":00.000";

     return DateTime.parse(dateTime);
 }

希望有所帮助。
