Android中的日期选择器
Android中的日期选择器
提问于 2010-07-21 20:52:56
任何人都可以在Android中发布简单日期选择器的示例代码。
如果在Android中不能使用日期选择器，则需要一个用于选择日期的选项。

使用DatePicker
http://developer.android.com/reference/android/widget/DatePicker.html
从API级别1开始即可使用
下面是一个如何使用DatePickerDialog的示例。
首先，向layout.xml添加一个TextView和一个按钮
<Button android:id="@+id/myDatePickerButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Choose Date"/>
<TextView android:id="@+id/showMyDate"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>接下来，您必须在布局的onCreate方法中初始化Button和TextView。您需要此类变量
private int mYear;
private int mMonth;
private int mDay;
private TextView mDateDisplay;
private Button mPickDate;
static final int DATE_DIALOG_ID = 0;这里是onCreate方法
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mDateDisplay = (TextView) findViewById(R.id.showMyDate);
mPickDate = (Button) findViewById(R.id.myDatePickerButton);
mPickDate.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
showDialog(DATE_DIALOG_ID);
}
});
// get the current date
final Calendar c = Calendar.getInstance();
mYear = c.get(Calendar.YEAR);
mMonth = c.get(Calendar.MONTH);
mDay = c.get(Calendar.DAY_OF_MONTH);
// display the current date
updateDisplay();
}UpdateDisplay方法：
private void updateDisplay() {
this.mDateDisplay.setText(
new StringBuilder()
// Month is 0 based so add 1
.append(mMonth + 1).append("-")
.append(mDay).append("-")
.append(mYear).append(" "));
}DatePickDialog的回调监听器
private DatePickerDialog.OnDateSetListener mDateSetListener =
new DatePickerDialog.OnDateSetListener() {
public void onDateSet(DatePicker view, int year,
int monthOfYear, int dayOfMonth) {
mYear = year;
mMonth = monthOfYear;
mDay = dayOfMonth;
updateDisplay();
}
};由showDialog()调用的onCreateDialog方法
@Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case DATE_DIALOG_ID:
return new DatePickerDialog(this,
mDateSetListener,
mYear, mMonth, mDay);
}
return null;
}希望它能帮上忙，用过了，效果很好。
