【问题描述】：

如何在我的项目中做到这一点？ 我有这样的广播接收器

public class AlarmManagerBroadcastReceiver extends BroadcastReceiver 

    public AlarmManagerBroadcastReceiver()
    

    @Override
    public void onReceive(Context context, Intent intent) 
        Toast.makeText(context, "Broadcast Receiveds", Toast.LENGTH_LONG).show();
        ActivityReminderBaru.sendingpush();
    

我在我的活动中设置了 sendpush()，就像这样

public class ActivityReminderBaru extends AppCompatActivity 
    @Override
    protected void onCreate(Bundle savedInstanceState) 
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_reminder_baru);

    

    public void sendingpush() 
        Intent intentnotif = new Intent(this, UserActivity.class);
        intentnotif.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intentnotif,
                PendingIntent.FLAG_ONE_SHOT);
        Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.ic_launcher)
                .setContentTitle("Staf Operasi 13")
                .setContentText(KeteranganHolder + TanggalHolder + WaktuHolder)
                .setAutoCancel(true)
                .setSound(defaultSoundUri)
                .setContentIntent(pendingIntent);
        NotificationManager notificationManager =
                (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
    

问题是，如何调用sendingpush();从我的活动到广播接收器？如果我运行这段代码，它可以完美运行，但是当广播接收器出现时，它会给我一个像这样的错误

Error:(16, 29) 错误：非静态方法sendingpush() 不能 从静态上下文引用

请帮我修复我的代码，谢谢

【问题讨论】：

Non-static variable cannot be referenced from a static context ...或“Non-static method cannot be referenced from a static context” error的可能重复

您正在尝试使用类名调用非静态方法，即sendingpush()。请仔细阅读上述评论中 Selvin 提供的参考资料

【参考方案1】：

将 sendpush() 提取到另一个名为 SendPushUtil 的类

public class SendPushUtil 

    public static void sendingpush(Context context) 
        Intent intentnotif = new Intent(context, UserActivity.class);
        intentnotif.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent pendingIntent = PendingIntent.getActivity(context, 0 /* Request code */, intentnotif,
                PendingIntent.FLAG_ONE_SHOT);
        Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.ic_launcher)
                .setContentTitle("Staf Operasi 13")
                .setContentText(KeteranganHolder + TanggalHolder + WaktuHolder)
                .setAutoCancel(true)
                .setSound(defaultSoundUri)
                .setContentIntent(pendingIntent);
        NotificationManager notificationManager =
                (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
    

然后使用

public class AlarmManagerBroadcastReceiver extends BroadcastReceiver 

    public AlarmManagerBroadcastReceiver() 
    

    @Override
    public void onReceive(Context context, Intent intent) 
        //Toast.makeText(context, "Broadcast Receiveds", Toast.LENGTH_LONG).show();
        SendPushUtil.sendingpush(context);
