Android滑动标签问题：Can'；t似乎没有更新UI，结果会重复n次

我用了两门课。一个用于后台服务，我正在那里收集一些信息，另一个我决定使用滑动选项卡视图来管理和组织我的信息/数据。在后台服务（就像我说的）中，我检索信息（主要是字符串类型）并通过intent将它们发送到主活动，此活动通过broadcastreceiver接收信息（这部分工作正常）。现在我遇到的问题是，当我试图将信息分发到不同的选项卡时，它会重复出现，而且似乎不会刷新。现在，我最关键的问题是重复信息部分。我要把我的代码放在这里，看看你们当中有没有聪明的人：D能帮我。我希望你能

启动broadcastreceiver以调用后台服务

    }

    getMenuInflater().inflate(R.menu.activity_main, menu);
    return true;
}

@Override
public void onTabSelected(ActionBar.Tab tab,
        FragmentTransaction fragmentTransaction) {
    // When the given tab is selected, switch to the corresponding page in
    // the ViewPager.
    mViewPager.setCurrentItem(tab.getPosition());

}

@Override
public void onTabUnselected(ActionBar.Tab tab,
        FragmentTransaction fragmentTransaction) {
}

@Override
public void onTabReselected(ActionBar.Tab tab,
        FragmentTransaction fragmentTransaction) {
}

        super(fm);
    }   

    @Override
    public Fragment getItem(int position) {
        // getItem is called to instantiate the fragment for the given page.
        // Return a DummySectionFragment (defined as a static inner class
        // below) with the page number as its lone argument.
        switch (position)
        {

等等

并将它们存储在字符串中

    infoData1 += ("Stuff1: " + stuff1 + "\n");
    infoData1 += ("Stuff2: " + stuff2 + "\n");

    infoData2 += ("Stuff3: " + Stuff3 + "\n");
    infoData2 += ("Stuff4: " + Stuff4 + "\n");


    infoData3 += ("Stuff5: " +  Stuff5 + "\n");
    infoData3 += ("Stuff6: " +  Stuff6 + "\n");

}


public static class Information1 extends Fragment {

    public static final String ARG_SECTION = "section_number";

    public Information1(){

}

@Override

        Bundle savedInstanceState) {

}
 }

        Log.d("InfoView2", infoData2);
        return info2View;
    }
}

    public static class Information3 extends Fragment {

        public static final String ARG_SECTION = "section_number";

        public Information3() {

        }

    @Override

        startService(intent);
        registerReceiver(broadcastReceiver, new IntentFilter(BroadcastService.BROADCAST_ACTION));
    }

    @Override
    public void onPause() {
        super.onPause();
        unregisterReceiver(broadcastReceiver);
        stopService(intent); 

    }
}

有什么想法吗=D

    infoData1 += ("Stuff1: " + stuff1 + "\n");
    infoData1 += ("Stuff2: " + stuff2 + "\n");

    infoData2 += ("Stuff3: " + Stuff3 + "\n");
    infoData2 += ("Stuff4: " + Stuff4 + "\n");


    infoData3 += ("Stuff5: " +  Stuff5 + "\n");
    infoData3 += ("Stuff6: " +  Stuff6 + "\n");

}
