我正在尝试制作一个简单的应用,例如在特定时间发出通知(下午4:25)
但是当我的手机在下午4:25收到通知时
我不知道是什么问题
这就是代码
MainActivity.class
package com.example.notifi;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.support.v4.app.NotificationCompat;
import android.util.Log;
public class Notificationmassage extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent arg1) {
showNotification(context);
}
private void showNotification(Context context) {
Log.i("notification", "visible");
PendingIntent contentIntent = PendingIntent.getActivity(context, 0,
new Intent(context, Notificationmassage.class), 0);
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle("xyz")
.setContentText("It will contain dummy content");
mBuilder.setContentIntent(contentIntent);
mBuilder.setDefaults(Notification.DEFAULT_SOUND);
mBuilder.setAutoCancel(true);
NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(1, mBuilder.build());
}
}
activity_main.xml中
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.notifi"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="21" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name=".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>
<receiver android:name="com.example.notifi.Notificationmassage"></receiver>
</application>
</manifest>
Notificationmassage.class
{{1}}
表现
{{1}}
这是我的所有代码
我不知道错误在哪里
请帮忙
谢谢
答案 0 :(得分:0)
在这种情况下,您无法使用explicit intent
,您必须使用implicit intent
new Intent(context, Notificationmassage.class)
是explicit intent
您应该将其更改为implicit intent
,即new Intent("com.example.notifi.NOTIFI_RECEIVER")
您需要在清单
中定义BroadcastReceiver<receiver android:name="com.example.notifi.Notificationmassage" >
<intent-filter>
<action android:name="com.example.notifi.NOTIFI_RECEIVER" />
</intent-filter>
</receiver>
