Android基础 DatePicker和TimePicker的使用

1.首先配置main.xml

<?xml version="1.0" encoding="utf-8"?>
lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView android:layout_width="fill_parent"
    android:id="@+id/TextView01" android:layout_height="wrap_content"
    android:text="@string/hello" />
<DatePicker android:id="@+id/DatePicker01"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">
</DatePicker>
<TimePicker android:id="@+id/TimePicker01"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">
</TimePicker>
<Button android:text="设置日期" android:id="@+id/Button01"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">
</Button>
<Button android:text="设置时间" android:id="@+id/Button02"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">
</Button>
lt;/LinearLayout>

 <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
	android:orientation="vertical" android:layout_width="fill_parent"
	android:layout_height="fill_parent">
	<TextView android:layout_width="fill_parent"
		android:id="@+id/TextView01" android:layout_height="wrap_content"
		android:text="@string/hello" />
	<DatePicker android:id="@+id/DatePicker01"
		android:layout_width="wrap_content"
		android:layout_height="wrap_content">
	</DatePicker>
	<TimePicker android:id="@+id/TimePicker01"
		android:layout_width="wrap_content"
		android:layout_height="wrap_content">
	</TimePicker>
	<Button android:text="设置日期" android:id="@+id/Button01"
		android:layout_width="wrap_content"
		android:layout_height="wrap_content">
	</Button>
	<Button android:text="设置时间" android:id="@+id/Button02"
		android:layout_width="wrap_content"
		android:layout_height="wrap_content">
	</Button>
</LinearLayout>
