Question

我正在BrodCastReceiver上做一个程序。因此，在我的程序中，当收到任何事件时，它会显示通知，但在点击相同的通知后，它不会启动指定的活动。

这是我的代码

public void onReceive(Context context, Intent i) {
    // TODO Auto-generated method stub
    Intent intent=new Intent(context, MainActivity.class);

    Toast.makeText(context, "Priority 2", Toast.LENGTH_SHORT).show();

    mBuilder=new NotificationCompat.Builder(context)
                .setSmallIcon(R.drawable.ic_launcher)
                .setContentTitle("My notification")
                .setContentText("Hello World!")
                .build();

     NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

     mNotificationManager.notify(1, mBuilder);
     PendingIntent.getBroadcast(context, 0, intent, Intent.FLAG_ACTIVITY_NEW_TASK);

     mNotificationManager.notify(1, mBuilder);
}

Answer 1

public void onReceive(Context context, Intent i) {
// TODO Auto-generated method stub
Intent intent=new Intent(context, MainActivity.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, intent, intent.FLAG_ACTIVITY_NEW_TASK);
Toast.makeText(context, "Priority 2", Toast.LENGTH_SHORT).show();

mBuilder=new NotificationCompat.Builder(context)
            .setSmallIcon(R.drawable.ic_launcher)
            .setContentTitle("My notification")
            .setContentText("Hello World!").setContentIntent(pendingIntent);
            .build();

 NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

 mNotificationManager.notify(1, mBuilder);
 PendingIntent.getBroadcast(context, 0, intent, Intent.FLAG_ACTIVITY_NEW_TASK);

 mNotificationManager.notify(1, mBuilder);
}

setContentIntent（pendingIntent）; 您需要在创建NotificationManager时设置此项。

您应该添加一个待处理的intent，它将响应click事件以打开相应的活性

试试这个：

public void onReceive(Context context, Intent i) {
    // TODO Auto-generated method stub
    Intent intent=new Intent(context, MainActivity.class);
           intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    PendingIntent   pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);

    Toast.makeText(context, "Priority 2", Toast.LENGTH_SHORT).show();

    mBuilder=new NotificationCompat.Builder(context)
                .setSmallIcon(R.drawable.ic_launcher)
                .setContentTitle("My notification")
                .setContentIntent(pendingIntent)
                .setContentText("Hello World!")
                .build();

     NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

     mNotificationManager.notify(1, mBuilder);



}

希望有所帮助

Intent intent=new Intent(context, MainActivity.class);
pendingIntent = PendingIntent.getBroadcast(context, 0, intent, intent.FLAG_ACTIVITY_NEW_TASK);
mBuilder=new NotificationCompat.Builder(context)
        .setSmallIcon(R.drawable.ic_launcher)
        .setContentTitle("My notification")
        .setContentText("Hello World!").setContentIntent(pendingIntent);
        .build();
 NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE); 
 mNotificationManager.notify(1, mBuilder)

首先初始化pendingIntent并在构建期间设置它。

单击“通知”后，活动未启动
