Android(安卓)通知Notification

在通知栏弹出发出的消息；类似于接受信息等等的一些小demo;

需要的activity_main.xml

[html] view plain copy

<LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<Button
android:id="@+id/send"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="发送通知"/>
<Button
android:id="@+id/clear"
android:layout_width="wrap_content"

一个小demo。点击发送通知按钮，则发送通知到设备的通知栏。点击清除通知则清除通知栏上的消息通知。
