Android基础 DatePicker和TimePicker的使用

1.首先配置main.xml

Java代码







<?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>

2.具体代码
