时间控件的使用

1、首先在oncreate方法里边初始化时间

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mQueue = Volley.newRequestQueue(mContext);
setDateTime();
}

2、逻辑代码：

“`

/**

* 设置日期

*/

private void setDateTime() {

final Calendar c = Calendar.getInstance();

mYear = c.get(Calendar.YEAR);
mMonth = c.get(Calendar.MONTH);
mDay = c.get(Calendar.DAY_OF_MONTH);
}

“`/**

* 更新日期显示

*/

private void updateDateDisplay() {

if (time != null) {

time.setText(new StringBuilder()

.append(mYear)

.append(“-“)

.append((mMonth + 1) < 10 ? “0” + (mMonth + 1)

: (mMonth + 1)).append(“-“).append(mDay));

}

}

/**
* 日期控件的事件
*/
class PickerOnDateSetListener implements DatePickerDialog.OnDateSetListener {

@Override
public void onDateSet(DatePicker arg0, int year, int monthOfYear,
int dayOfMonth) {
mYear = year;
mMonth = monthOfYear;
mDay = dayOfMonth;

updateDateDisplay();
}

}

@Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case DATE_DIALOG_ID:
return new DatePickerDialog(this, new PickerOnDateSetListener(),
mYear, mMonth, mDay);
}
return null;
}

@Override
protected void onPrepareDialog(int id, Dialog dialog) {
switch (id) {
case DATE_DIALOG_ID:
((DatePickerDialog) dialog).updateDate(mYear, mMonth, mDay);
break;
}
}
@Override
public void onClick(View v) {
super.onClick(v);
switch (v.getId()) {
case R.id.et_time:
showDialog(DATE_DIALOG_ID);
break;
}
