问题描述
我要创建通知，并要显示它在广播接收器的onReceiver。但我不能够做到这一点。为什么呢？
在code为我的类是：
公共类AlarmNotificationReceiver扩展广播接收器{
//私人意图意图;
私人NotificationManager notificationManager;
私人的通知的通知;
@覆盖
公共无效的onReceive（上下文的背景下，意图意图）{
// TODO自动生成方法存根 长值1 = intent.getLongExtra（参数1，0）;
字符串值2 = intent.getStringExtra（参数2）;
Toast.makeText（背景下，你好！怎么řú？，Toast.LENGTH_SHORT）.show（）;
addTwoMonthNotification（）;}私人无效addTwoMonthNotification（）{
notificationManager =（NotificationManager）getSystemService（Context.NOTIFICATION_SERVICE）;
INT图标= R.drawable.icon;
CharSequence的文字=你的大写金额是由于在此日期;
CharSequence的contentTitle =税计算器应用程序;
CharSequence的contentText = + System.currentTimeMillis的（）+您的税额的是由于;
时长= System.currentTimeMillis的（）; 意向意图=新意图（这一点，NotificationViewer.class）;
的PendingIntent contentIntent = PendingIntent.getActivity（这一点，0，意向，0）;
通知=新的通知（图标，文字的时候）; 长[] =振动{} 0100200300;
notification.vibrate =震动; notification.ledARGB = Color.RED;
notification.ledOffMS = 300;
notification.ledOnMS = 300; notification.defaults | = Notification.DEFAULT_LIGHTS;
//notification.flags | = Notification.FLAG_SHOW_LIGHTS; notification.setLatestEventInfo（这一点，contentTitle，contentText，contentIntent）;
notificationManager.notify（NotificationConstants.NOTIFICATION_ID，通知）;
}
}
给出解决方案了。
谢谢你。
你见过这样的：
startActivity()从广播接收器
它看起来并不像你正在使用 Context.registerReceiver（）所以你有你的接收机静态添加到清单，如果你还没有：
请确保您已在清单以下
＆lt;接收机器人：名字=。AlarmNotificationReceiver＆GT;
＆所述;意图滤光器＆gt;
＆lt;作用机器人：名字=android.intent.action.PHONE_STATE/＆GT;
＆所述; /意图滤光器＆gt;
＆LT; /接收器＆GT;
以上， PHONE_STATE 就是这样可与广播接收器

希望帮助！
I am going to create the notification and want to show it on the onReceiver of the BroadcastReceiver. But i am not able to do it. why ?The code for my class is:
public class AlarmNotificationReceiver extends BroadcastReceiver{
//private Intent intent;
private NotificationManager notificationManager;
private Notification notification;
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
long value1 = intent.getLongExtra("param1", 0);
String value2 = intent.getStringExtra("param2");
Toast.makeText(context, "Hello! How r u ?", Toast.LENGTH_SHORT).show();
addTwoMonthNotification();
}
private void addTwoMonthNotification(){
notificationManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
int icon = R.drawable.icon;
CharSequence text = "Your amout is due on this date";
CharSequence contentTitle = "Tax Calculator App";
CharSequence contentText = "Your tax amount is due on the "+System.currentTimeMillis()+"";
long when = System.currentTimeMillis();
Intent intent = new Intent(this, NotificationViewer.class);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, intent, 0);
notification = new Notification(icon,text,when);
long[] vibrate = {0,100,200,300};
notification.vibrate = vibrate;
notification.ledARGB = Color.RED;
notification.ledOffMS = 300;
notification.ledOnMS = 300;
notification.defaults |= Notification.DEFAULT_LIGHTS;
//notification.flags |= Notification.FLAG_SHOW_LIGHTS;
notification.setLatestEventInfo(this, contentTitle, contentText, contentIntent);
notificationManager.notify(NotificationConstants.NOTIFICATION_ID, notification);
}
}
Give Solution for it.Thanks.
Have you seen this:startActivity() from BroadcastReceiver
It doesn't look like you are using Context.registerReceiver() so you would have to statically add your receiver to the manifest, if you haven't already:
make sure you have the following in your manifest
<receiver android:name=".AlarmNotificationReceiver">
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>
</receiver>
Above, PHONE_STATE is just an example of an intent that may be used in conjuntion with the BroadcastReceiver
