1.分析
状态通知栏主要涉及到2个类: Notification 和 NotificationManager
Notification为通知信息类,它里面对应了通知栏的各个属性
NotificationManager : 是状态栏通知的管理类,负责发通知、清除通知等操作。
注意:NotificationManager 是一个系统Service,所以必须通过 getSystemService(NOTIFICATION_SERVICE)方法来获取,方法如下。
:NotificationManager mNotificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
2.流程
第一步:
创建一个通知栏的Builder构造类 (Create a Notification Builder)
第二步:
定义通知栏的Action (Define the Notification's Action)
第三步:
设置通知栏点击事件 (Set the Notification's Click Behavior)
第四步:
通知 (Issue the Notification)
3.代码
实现系统默认的通知栏效果:
第一步:获取状态通知栏管理
NotificationManager mNotificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
第二步:实例化通知栏构造器NotificationCompat.Builder:
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this)
第三步:对Builder进行配置:
- mBuilder.setContentTitle("测试标题")//设置通知栏标题
- .setContentText("测试内容") /<span style="font-family: Arial;">/设置通知栏显示内容</span>
- .setContentIntent(getDefalutIntent(Notification.FLAG_AUTO_CANCEL)) //设置通知栏点击意图
- // .setNumber(number) //设置通知集合的数量
- .setTicker("测试通知来啦") //通知首次出现在通知栏,带上升动画效果的
- .setWhen(System.currentTimeMillis())//通知产生的时间,会在通知信息里显示,一般是系统获取到的时间
- .setPriority(Notification.PRIORITY_DEFAULT) //设置该通知优先级
- // .setAutoCancel(true)//设置这个标志当用户单击面板就可以让通知将自动取消
- .setOngoing(false)//ture,设置他为一个正在进行的通知。他们通常是用来表示一个后台任务,用户积极参与(如播放音乐)或以某种方式正在等待,因此占用设备(如一个文件下载,同步操作,主动网络连接)
- .setDefaults(Notification.DEFAULT_VIBRATE)//向通知添加声音、闪灯和振动效果的最简单、最一致的方式是使用当前的用户默认设置,使用defaults属性,可以组合
- //Notification.DEFAULT_ALL Notification.DEFAULT_SOUND 添加声音 // requires VIBRATE permission
- .setSmallIcon(R.drawable.ic_launcher);//设置通知小ICON
第四步:RemoteViews 自定义 view
RemoteViews remoteViews = new RemoteViews(getPackageName(), R.layout.notification);
remoteViews.setTextViewText(R.id.tv_up, "测试标题");
remoteViews.setTextViewText(R.id.tv_down, "测试文本");
Intent intent = new Intent(ACTION_BTN);
intent.putExtra(INTENT_NAME, INTENT_BTN_LOGIN);
设置不同区域的点击的pendingIntent
PendingIntent intentpi = PendingIntent.getBroadcast(this, 1, intent, PendingIntent.FLAG_UPDATE_CURRENT);
remoteViews.setOnClickPendingIntent(R.id.btn_login, intentpi);
Intent intent2 = new Intent();
intent2.setClass(this, MainActivity.class);
intent2.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
PendingIntent intentContent = PendingIntent.getActivity(this, 0, intent2, PendingIntent.FLAG_UPDATE_CURRENT);
remoteViews.setOnClickPendingIntent(R.id.close_iv,intentContent);
默认的Notification只能通过setContentIntent设置整体的点击事件。不过通过RemoteViews我们可以设置不同地方不同的点击事件,当然这里的事件指的是PendingIntent。如下,设置了点击R.id.notice_view_type_0打开一个Activity,而点击R.id.close_iv会发出一个广播,可以通过这个广播的广播接收器来做一些事情,如这里是关闭当前的Notification。另外还可以打开一个Service。

下面贴上测试代码
public class TestNotifition {
public final static String ACTION_BTN = "com.example.notification.btn.login";
public final static String INTENT_NAME = "btnid";
public final static int INTENT_BTN_LOGIN = 1;
NotificationBroadcastReceiver mReceiver;
public void notification(Context context) {
unregeisterReceiver(context);
intiReceiver(context);
// FmService mFmService = new FmService();
// FmService.LocalStation mStation= mFmService.new LocalStation(context);
RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.notification);
// remoteViews.setTextViewText(R.id.tv_up, mStation.isFm() ? "FM" : "AM");
remoteViews.setTextViewText(R.id.tv_up, "FM");
remoteViews.setTextViewText(R.id.tv_down, "87.5");
Intent intent = new Intent(ACTION_BTN);
intent.putExtra(INTENT_NAME, INTENT_BTN_LOGIN);
PendingIntent intentpi = PendingIntent.getBroadcast(context, 1, intent, PendingIntent.FLAG_UPDATE_CURRENT);
remoteViews.setOnClickPendingIntent(R.id.btn_login, intentpi);
Intent intent2 = new Intent();
intent2.setClass(context, SqrFmMainActivity.class);
intent2.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
PendingIntent intentContent = PendingIntent.getActivity(context, 0, intent2, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
builder.setOngoing(false);
builder.setAutoCancel(true);
builder.setContent(remoteViews);
builder.setTicker("正在使用FM电台收听");
builder.setSmallIcon(R.drawable.ic_launcher);//通知图标
builder.setPriority(NotificationCompat.PRIORITY_HIGH);//通知优先级
Bitmap bitmap = BitmapFactory.decodeResource(context.getResources(),R.drawable.searchbarbtn3);
builder.setLargeIcon(bitmap);
builder.setNumber(1024);
builder.setWhen(System.currentTimeMillis());
Notification notification = builder.build();
// notification.defaults = Notification.DEFAULT_SOUND;
notification.flags = Notification.FLAG_AUTO_CANCEL;
notification.contentIntent = intentContent;
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, notification);
}
public void intiReceiver(Context context) {
mReceiver = new NotificationBroadcastReceiver();
IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction(ACTION_BTN);
context.getApplicationContext().registerReceiver(mReceiver, intentFilter);
}
public void unregeisterReceiver(Context context) {
if (mReceiver != null) {
context.getApplicationContext().unregisterReceiver(mReceiver);
mReceiver = null;
}
}
public class NotificationBroadcastReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (action.equals(ACTION_BTN)) {
int btn_id = intent.getIntExtra(INTENT_NAME, 0);
switch (btn_id) {
case INTENT_BTN_LOGIN:
Toast.makeText(context, "红红火火恍恍惚惚哈哈哈哈", Toast.LENGTH_SHORT).show();
unregeisterReceiver(context);
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.cancel(0);
break;
}
}
}
}
}
