Android之DatePickerDialog用法（日历的用法）

该方法实现的调用系统Api，和android的版本，手机的牌子有关，实现不同的界面。不一定是入下图所示：

                                    

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical" >
    <TextView
        android:id="@+id/text01"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="查询日期:"
        android:textSize="18sp"
        />
    <TextView
        android:id="@+id/tvDate"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/text01"
        android:layout_alignLeft="@id/text01"
        />
    <Button
        android:id="@+id/btnDatePicker"
        android:text="编辑"
        android:layout_toRightOf="@id/tvDate"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:onClick="show"
        android:layout_alignTop="@id/tvDate"
        />
</RelativeLayout>
