安卓事件总线传递数据从活动到选项卡片段

我在我的程序中有5个选项卡片段，我想从我的工具栏按钮传递数据到5选项卡片段，但问题是当我单击我的工具栏按钮时它只传递3片段，人有想法来解决这个安卓事件总线传递数据从活动到选项卡片段

主要活动

这是MainActivity我的onclick功能

public void editpage(View view) { 

    ToggleButton etMessage = (ToggleButton) findViewById(R.id.toggleButton); 
    Events.ActivityFragmentMessage activityFragmentMessageEvent = new Events.ActivityFragmentMessage(String.valueOf(etMessage.getText())); 
    Events.ActivityFragmentMessage2 activityFragmentMessageEvent2 = new Events.ActivityFragmentMessage2(String.valueOf(etMessage.getText())); 
    Events.ActivityFragmentMessage3 activityFragmentMessageEvent3 = new Events.ActivityFragmentMessage3(String.valueOf(etMessage.getText())); 
    Events.ActivityFragmentMessage4 activityFragmentMessageEvent4 = new Events.ActivityFragmentMessage4(String.valueOf(etMessage.getText())); 
    Events.ActivityFragmentMessage5 activityFragmentMessageEvent5 = new Events.ActivityFragmentMessage5(String.valueOf(etMessage.getText())); 
    GlobalBus.getBus().post(activityFragmentMessageEvent); 
    GlobalBus.getBus().post(activityFragmentMessageEvent2); 
    GlobalBus.getBus().post(activityFragmentMessageEvent3); 
    GlobalBus.getBus().post(activityFragmentMessageEvent4); 
    GlobalBus.getBus().post(activityFragmentMessageEvent5); 

}

list_fragment2

这是我收到的数据一旦切换按钮上MainActivity

点击

@Override 
public void onStart() { 
    super.onStart(); 
    GlobalBus.getBus().register(this); 
} 
@Subscribe 
public void getMessage(Events.ActivityFragmentMessage activityFragmentMessage) { 

    messageView2 = (TextView) getView().findViewById(R.id.sum2); 
    messageView2.setText(String.valueOf(activityFragmentMessage.getMessage())); 
    messageView2.setText(activityFragmentMessage.getMessage()); 
    i = messageView2.getText().toString(); 
    result = Integer.parseInt(i); 
    if (result == 1) { 
     Nsum[0]++; 
     editor.putInt(PREFS_KEY,Nsum[0]); 
     editor.commit(); 
     FragmentTransaction ft = getFragmentManager().beginTransaction(); 
     ft.detach(list_fragment2.this).attach(list_fragment2.this).commit(); 

    }else if (result ==0){ 
     editor.remove(PREFS_KEY); 
     editor.commit(); 
     FragmentTransaction ft = getFragmentManager().beginTransaction(); 
     ft.detach(list_fragment2.this).attach(list_fragment2.this).commit(); 
    }

    messageView3.setText(String.valueOf(activityFragmentMessage3.getMessage3())); 
    messageView3.setText(activityFragmentMessage3.getMessage3()); 
    i = messageView3.getText().toString(); 
    result = Integer.parseInt(i); 
    if (result == 1) { 
     Nsum[0]++; 
     editor.putInt(PREFS_KEY,Nsum[0]); 
     editor.commit(); 
     FragmentTransaction ft = getFragmentManager().beginTransaction(); 
     ft.detach(orderlist_fragment.this).attach(orderlist_fragment.this).commit(); 

    }else if (result ==0){

如果你正在使用'TabLayout'，它首先会膨胀一些碎片，在这种情况下，我猜想是3。您的其他片段尚未初始化。因此，您在创建数据时必须检查数据。 –

@NaveenDissanayake谢谢，你是否意味着问题出现在我的tablayout中？ – AnthonyTang

我的意思是你认为它的工作方式。当你使用'TabLayout'时，它不会膨胀所有的片段。这实际上是预期的方式。 –
