android通知(Notification)的使用

需要注意的几点：

1.通知的类型，一般普通的消息事件和正在进行的事件

2.通知的布局是可以自定义的

3.通知在android4.1以后，还支持一种detail的通知，（就是可扩展的）

4.通知的行为，常规的和按照堆栈顺序的

activity的配置：

<activity
android:name="com.example.testnotification.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<!-- 确保这次活动是独立的，不影响应用默认的使用范围 -->
<activity
android:name="com.example.testnotification.ResultActivity"
android:excludeFromRecents="true"
android:label="@string/title_activity_result"
android:launchMode="singleTask"
android:taskAffinity="" >
</activity>

<!-- 具有保持应用程序堆栈顺序的，通知 -->
<activity
android:name="com.example.testnotification.Result2Activity"
android:label="@string/title_activity_result2"
android:parentActivityName="com.example.testnotification.MainActivity" >
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="com.example.testnotification.MainActivity" />
</activity>

示例代码：

/**
* 测试发送一个普通行为的通知 通知在点击后，进入resultactivity，点击返回将直接结束
*
* @param v
*/
public void onBtn1(View v) {
// 构造通知，目前已经将直接使用构造方法的方式淘汰了
NotificationCompat.Builder builder = new NotificationCompat.Builder(
this);
builder.setContentTitle("jiba");
builder.setContentTitle("狗日傻逼");
builder.setAutoCancel(true);
builder.setSmallIcon(R.drawable.ic_launcher);
// 通知的活动
Intent notifyIntent = new Intent(this, ResultActivity.class);
// Sets the Activity to start in a new, empty task
notifyIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK
| Intent.FLAG_ACTIVITY_CLEAR_TASK);
// Creates the PendingIntent
PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
notifyIntent, PendingIntent.FLAG_UPDATE_CURRENT);

// Puts the PendingIntent into the notification builder
builder.setContentIntent(contentIntent);

// 最后完成通知发送
NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(1, builder.build());
}

/**
* 发送保持堆栈的通知
* @param v
*/
public void onBtn2(View v) {
Intent resultIntent = new Intent(this, Result2Activity.class);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
// Adds the back stack
stackBuilder.addParentStack(Result2Activity.class);
// Adds the Intent to the top of the stack
stackBuilder.addNextIntent(resultIntent);
// Gets a PendingIntent containing the entire back stack
PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(0,
PendingIntent.FLAG_UPDATE_CURRENT);

NotificationCompat.Builder builder = new NotificationCompat.Builder(
this);
builder.setContentTitle("jiba2");
builder.setContentTitle("狗日傻逼2");
builder.setSmallIcon(R.drawable.ic_launcher);
builder.setAutoCancel(true);
builder.setTicker("oh,jibalema");
builder.setContentIntent(resultPendingIntent);

NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(10, builder.build());
}
