我正在尝试将time picker添加到日期选择器中。我是java的初学者，也许有人可以告诉我正确的方法？我希望时间选择器显示在日历视图的顶部，在我选择日期后，时间选择器弹出。可能吗 ？在xml文件中，只有很少的EditText字段已在此类中声明。

Android使用android.widget.TimePicker component设置时间非常容易。
请参阅this Tutorial在这里，您可以看到用户如何使用易于使用的android.app.TimePickerDialog对话框选择小时和分钟。

尝试以下代码：
date_time_layout.xml
<DatePicker
android:id="@+id/datePicker1"
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight="1"
android:calendarViewShown="false" > <!-- style="@style/date_picker_style" -->
</DatePicker>
<TimePicker
android:id="@+id/timePicker1"
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight="1" >
</TimePicker>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp" >
<Button
android:id="@+id/btnCancelDT"
android:layout_width="0dip"
android:layout_height="wrap_content"
android:layout_weight="1"
android:background="@drawable/button_selector"
android:text="Cancel"
android:textColor="@color/white"
android:textStyle="bold" />
<Button
android:id="@+id/btnSetDT"
android:layout_width="0dip"
android:layout_height="wrap_content"
android:layout_weight="1"
android:background="@drawable/button_selector"
android:text="Set"
android:textColor="@color/white"
android:textStyle="bold" />
</LinearLayout>
活动类：
public void showDateTimePickerDialog() {
final Dialog dialog = new Dialog(this);
dialog.setContentView(R.layout.date_time_layout);
dialog.setTitle("Set Schedule Call");
dialog.show();
Button btnCancel = (Button)dialog.findViewById(R.id.btnCancelDT);
Button btnSet = (Button)dialog.findViewById(R.id.btnSetDT);
final DatePicker dp = (DatePicker)dialog.findViewById(R.id.datePicker1);
final TimePicker tp = (TimePicker)dialog.findViewById(R.id.timePicker1);
btnCancel.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
dialog.dismiss();
}
});
btnSet.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
String am_pm = "";
// TODO Auto-generated method stub
int m = dp.getMonth()+1;
int d = dp.getDayOfMonth();
int y = dp.getYear();
int h = tp.getCurrentHour();
int min = tp.getCurrentMinute();
String strm = String.valueOf(min);
if(strm.length()==1){
strm = "0"+strm;
}
if(h>12){
am_pm = "PM";
h = h-12;
}else{
am_pm = "AM";
}
date = m+"/"+d+"/"+y+" "+h+":"+strm+":00 "+am_pm;
time = h+":"+strm+" "+am_pm;
System.out.println("Date: " + date +" Time: "+ time);
dialog.dismiss();
}
});
}
按下按钮或根据需要调用此方法。
