实现的效果就是在同一个布局上显示日期选择和时间选择，时间不准确bug修复
1、自定义类DateTimePickDialogUtil.java
public class DateTimePickDialogUtil implements OnDateChangedListener,
OnTimeChangedListener {
private DatePicker datePicker;
private TimePicker timePicker;
private AlertDialog ad;
private String dateTime;
private String initDateTime;
private Activity activity; /**
* 日期时间弹出选择框构造函数
*
* @param activity
* ：调用的父activity
* @param initDateTime
* 初始日期时间值，作为弹出窗口的标题和日期时间初始值
*/
public DateTimePickDialogUtil(Activity activity, String initDateTime) {
this.activity = activity;
this.initDateTime = initDateTime; } public void init(DatePicker datePicker, TimePicker timePicker) {
Calendar calendar = Calendar.getInstance();
if (!(null == initDateTime || "".equals(initDateTime))) {
calendar = this.getCalendarByInintData(initDateTime);
} else {
initDateTime = calendar.get(Calendar.YEAR) + "年"
+ calendar.get(Calendar.MONTH) + "月"
+ calendar.get(Calendar.DAY_OF_MONTH) + "日 "
+ calendar.get(Calendar.HOUR_OF_DAY) + ":"
+ calendar.get(Calendar.MINUTE);
} datePicker.init(calendar.get(Calendar.YEAR),
calendar.get(Calendar.MONTH),
calendar.get(Calendar.DAY_OF_MONTH), this);
timePicker.setIs24HourView(true);
timePicker.setCurrentHour(calendar.get(Calendar.HOUR_OF_DAY));
timePicker.setCurrentMinute(calendar.get(Calendar.MINUTE));
} /**
* 弹出日期时间选择框方法
*
* @param inputDate
* :为需要设置的日期时间文本编辑框
* @return
*/
public AlertDialog dateTimePicKDialog(final EditText inputDate) {
LinearLayout dateTimeLayout = (LinearLayout) activity
.getLayoutInflater().inflate(R.layout.common_datetime, null);
datePicker = (DatePicker) dateTimeLayout.findViewById(R.id.datepicker);
timePicker = (TimePicker) dateTimeLayout.findViewById(R.id.timepicker);
init(datePicker, timePicker);
timePicker.setIs24HourView(true);
timePicker.setOnTimeChangedListener(this); ad = new AlertDialog.Builder(activity)
.setTitle(initDateTime)
.setView(dateTimeLayout)
.setPositiveButton("确定", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
inputDate.setText(dateTime);
}
})
.setNegativeButton("取消", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
inputDate.setText("");
}
}).show(); onDateChanged(null, 0, 0, 0);
return ad;
} public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
onDateChanged(null, 0, 0, 0);
} public void onDateChanged(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
// 获得日历实例
Calendar calendar = Calendar.getInstance(); calendar.set(datePicker.getYear(), datePicker.getMonth(),
datePicker.getDayOfMonth(), timePicker.getCurrentHour(),
timePicker.getCurrentMinute());
SimpleDateFormat sdf = new SimpleDateFormat("yyyy年MM月dd日 HH:mm"); dateTime = sdf.format(calendar.getTime());
ad.setTitle(dateTime);
} /**
* 实现将初始日期时间2012年07月02日 16:45 拆分成年 月 日 时 分 秒,并赋值给calendar
*
* @param initDateTime
* 初始日期时间值 字符串型
* @return Calendar
*/
private Calendar getCalendarByInintData(String initDateTime) {
Calendar calendar = Calendar.getInstance(); // 将初始日期时间2012年07月02日 16:45 拆分成年 月 日 时 分 秒
String date = spliteString(initDateTime, "日", "index", "front"); // 日期
String time = spliteString(initDateTime, "日", "index", "back"); // 时间 String yearStr = spliteString(date, "年", "index", "front"); // 年份
String monthAndDay = spliteString(date, "年", "index", "back"); // 月日 String monthStr = spliteString(monthAndDay, "月", "index", "front"); // 月
String dayStr = spliteString(monthAndDay, "月", "index", "back"); // 日 String hourStr = spliteString(time, ":", "index", "front"); // 时
String minuteStr = spliteString(time, ":", "index", "back"); // 分 int currentYear = Integer.valueOf(yearStr.trim()).intValue();
int currentMonth = Integer.valueOf(monthStr.trim()).intValue() - 1;
int currentDay = Integer.valueOf(dayStr.trim()).intValue();
int currentHour = Integer.valueOf(hourStr.trim()).intValue();
int currentMinute = Integer.valueOf(minuteStr.trim()).intValue(); calendar.set(currentYear, currentMonth, currentDay, currentHour,
currentMinute);
return calendar;
} /**
* 截取子串
*
* @param srcStr
* 源串
* @param pattern
* 匹配模式
* @param indexOrLast
* @param frontOrBack
* @return
*/
public static String spliteString(String srcStr, String pattern,
String indexOrLast, String frontOrBack) {
String result = "";
int loc = -1;
if (indexOrLast.equalsIgnoreCase("index")) {
loc = srcStr.indexOf(pattern); // 取得字符串第一次出现的位置
} else {
loc = srcStr.lastIndexOf(pattern); // 最后一个匹配串的位置
}
if (frontOrBack.equalsIgnoreCase("front")) {
if (loc != -1)
result = srcStr.substring(0, loc); // 截取子串
} else {
if (loc != -1)
result = srcStr.substring(loc + 1, srcStr.length()); // 截取子串
}
return result;
} }
2、自定义界面common_datetime.xml
<?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" > <DatePicker
android:id="@+id/datepicker"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:calendarViewShown="false" /> <TimePicker
android:id="@+id/timepicker"
android:layout_width="wrap_content"
android:layout_height="wrap_content" /> </LinearLayout>
3、DateTimePickerActivity.java
public class DateTimePickerActivity extends Activity {
/** Called when the activity is first created. */
private EditText startDateTime;
private EditText endDateTime;
//private String initStartDateTime = "2013年9月3日 14:44"; // 初始化开始时间
private String initStartDateTime = null; // 初始化开始时间
private String initEndDateTime = null; // 初始化结束时间
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// 两个输入框
startDateTime = (EditText) findViewById(R.id.inputDate);
endDateTime = (EditText) findViewById(R.id.inputDate2);
startDateTime.setText(initStartDateTime);
endDateTime.setText(initEndDateTime);
startDateTime.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
DateTimePickDialogUtil dateTimePicKDialog = new DateTimePickDialogUtil(
DateTimePickerActivity.this, startDateTime.getText()==null?null:startDateTime.getText().toString());
dateTimePicKDialog.dateTimePicKDialog(startDateTime);
}
});
endDateTime.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
DateTimePickDialogUtil dateTimePicKDialog = new DateTimePickDialogUtil(
DateTimePickerActivity.this, endDateTime.getText()==null?null:endDateTime.getText().toString());
dateTimePicKDialog.dateTimePicKDialog(endDateTime);
}
});
}
}
