時間選擇器:DatePicker 和TimePicker

jopen 9年前發布 | 122K 次閱讀 Android Android開發 移動開發


1.介紹DatePicker和TimePicker兩種實現動態輸入日期和時間的功能

2.介紹DataPickerDialog和TimePickerDialog兩種實現動態輸入日期和時間的對話框

3，介紹兩組針對監測日期時間改變的監聽器包含：

              OnDataChangedListener和OnTimeChangedListener()

              OnDataSetListener和OnTimeSetListener()


     >當用戶更改了DataPicker里的年，月，日時，將觸發OnDataChangedListener監聽器的OnDataChange()事件

     >當用戶更改了TimePicker里的時，分時，將觸發OnTimeChangedListener監聽器的OnTimeChanged()事件


    >當用戶更改了DataPickerDialog里的年，月，日時，將觸發OnDataSetListener監聽器的onDataSet()事件

    >當用戶更改了TimePickerDialog里的時，分時，將觸發OnTimeSetListener監聽器的onTimeSet()事件


1.xml布局：兩個空間DatePicker 和TimePicker 

<RelativeLayout xmlns:android="


<DatePicker
    android:id="@+id/datePicker1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginTop="20dp"
    android:layout_alignParentLeft="true"
    android:layout_alignParentRight="true"
    android:layout_alignParentTop="true" />


<TimePicker
    android:id="@+id/timePicker1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@+id/datePicker1"
    android:layout_centerHorizontal="true"
    android:layout_marginTop="20dp" />




</RelativeLayout></pre>




2.java代碼部分 


public class MainActivity extends Activity {


private DatePicker datePicker;
private TimePicker timePicker;
private Calendar cal;
private int year;
private int month;
private int day;
private int hour;
private int minute;


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


//獲取一個日歷對象
cal = Calendar.getInstance();
//獲取年月日時分秒的信息
year = cal.get(Calendar.YEAR);
month = cal.get(Calendar.MONTH)+1;
day = cal.get(Calendar.DAY_OF_MONTH);
hour = cal.get(Calendar.HOUR_OF_DAY);
minute = cal.get(Calendar.MINUTE);
setTitle(year + "-" + month + "-" + day + "  " + hour + ":" + minute);
datePicker = (DatePicker) findViewById(R.id.datePicker1);
timePicker = (TimePicker) findViewById(R.id.timePicker1);


//datePicker初始化
datePicker.init(year, cal.get(Calendar.MONTH), day, new OnDateChangedListener() {


@Override
public void onDateChanged(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
// TODO Auto-generated method stub
setTitle(year + "-" + (monthOfYear + 1) + "-" + dayOfMonth);
}
});


timePicker.setOnTimeChangedListener(new OnTimeChangedListener() {


@Override
public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
// TODO Auto-generated method stub
setTitle(hourOfDay + ":" + minute);
}
});
new DatePickerDialog(this, new OnDateSetListener() {


@Override
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
// TODO Auto-generated method stub
setTitle(year + "-" + (monthOfYear + 1) + "-" + dayOfMonth);
}
}, year, cal.get(Calendar.MONTH), day).show();


new TimePickerDialog(this, new OnTimeSetListener() {


@Override
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
// TODO Auto-generated method stub
setTitle(hourOfDay + ":" + minute);
}
}, hour, minute, true).show();
}


}</pre>
