Android中Notification的使用以及自定义

界面很简单：

activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    style="@style/all" >    <Button        style="@style/all"        android:onClick="onclick"        android:text="通知" />    <Button        style="@style/all"        android:onClick="onclick2"        android:text="自定义通知" /></LinearLayout>

content.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical" >    <ImageView        android:layout_width="match_parent"        android:layout_height="match_parent"        android:src="@drawable/ic_launcher" /></LinearLayout>

以下是主体的代码：

MainActivity.java

package com.example.notification;import android.app.Activity;import android.app.Notification;import android.app.NotificationManager;import android.app.PendingIntent;import android.content.Context;import android.content.Intent;import android.os.Bundle;import android.view.View;import android.widget.RemoteViews;import android.widget.RemoteViews.RemoteView;public class MainActivity extends Activity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);}public void onclick(View v) {// 1.得到通知管理器NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);// 2.构建通知Notification noti = new Notification(android.R.drawable.stat_notify_chat, "这是提示消息 ",System.currentTimeMillis());// 3.设置通知栏点击事件Intent itent = new Intent(this, MainActivity.class);PendingIntent pendingIntent = PendingIntent.getActivity(this, 100,itent, 0);noti.setLatestEventInfo(this, "通知的标题", "通知的内容", pendingIntent);noti.flags = Notification.FLAG_AUTO_CANCEL;// 点击后自动消失// 4.发送通知notificationManager.notify(100, noti);}public void onclick2(View v) {// 1.得到通知管理器NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);// 2.构建通知Notification noti = new Notification();noti.tickerText = "拦截到了N条信息";noti.icon = R.drawable.ic_launcher;RemoteViews conteView = new RemoteViews(getPackageName(),R.layout.content);noti.contentView = conteView;//通知显示的布局Intent itent = new Intent(this, OtherActivity.class);PendingIntent pendingIntent = PendingIntent.getActivity(this, 100,itent, 0);noti.contentIntent = pendingIntent;//点击事件noti.flags = Notification.FLAG_AUTO_CANCEL;// 点击后自动消失// 4.发送通知notificationManager.notify(100, noti);}}

OtherActivity.java

package com.example.notification;import android.app.Activity;import android.os.Bundle;public class OtherActivity extends Activity{protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.content);}}
