如何在导航抽屉通信的两个片段之间的数据 [英] How to communicate data between two fragments in a navigation drawer

问题描述

我有一个抽屉式导航栏，其中包含不同的片段（每个项目显示的片段），我想从一个片段到另一个传递数据。（我有一个包含导航抽屉，其中有一个列表只是一个活动的片段）。

I have a navigation drawer which contains different fragments (each item display a fragment) and i'd like to pass data from a fragment to another.(I have just one activity that contain a navigation drawer in which a have a list of fragments).

我已经尝试了许多解决方案（捆绑和意向），但我没能解决我的问题。

I have tried many solutions (Bundle and intent) but I couldn't solve my problem.

任何一个可以帮助我pleaaase。

Can any one help me pleaaase.

推荐答案

当您点击 NavigationDrawer ，您可以用 setArguments内（）方法通过声明你DATAS一个捆绑如下：

When you click inside your NavigationDrawer, you can use setArguments() method to declare your datas via a Bundle as follows:

// int id = 1;
MyFragment newFragment = new MyFragment();
Bundle args = new Bundle();
args.putInt("ARG_DATA_ID", id);
newFragment.setArguments(args);
// replace and commit with fragmenttransaction  

然后，您的片段里，使用 getArgument（）方法如下所示：

Bundle arg = getArguments();
int id_pass = arg.getInt("ARG_DATA_ID");
// id_pass = 1;  

不过，也许你可以找到一些有用的提示到这个话题：与其他通信片段的。

更新：

好吧，我试图从code做出了榜样，但是，它的嗡嗡声..硬）。

Well, I tried to make an example from your code but, it's hum.. hard ;).

1. 您没有收到的参数，因为的SelectItem 方法，你不菜单片段（但你的交换机是怎么做的，你在正确的方式）。您尝试separatly发送说法，但在其他捆绑当你在点击 buttonValidatePrices 设置这是不发送或任何东西。刚刚创建的，没有什么存储到它的价值，以及..它不涉及到 FragmentTransaction 。

1. You don't receive an argument because in SelectItem method, you don't send any argument with Menu fragment (but your switch is how to do, you're on the right way). You try separatly to send an argument but in other Bundle when you click on buttonValidatePrices in setting which it is not send or anything. Just created, a value stored into it, and nothing.. it's not related to the FragmentTransaction.

在菜单，您尝试接受这一点：

Inside Menu, you try to receive with this:

Log.i("bundlebundlebundle", getArguments().getString("price_"+"pizza",Default));  

不过，我认为这将是更好的：

But I think it will be better with:

Log.i("bundlebundlebundle", getArguments().getString("price_pizza"));  

您应该：​​

第一的（以MainActivity） = 获取的值从 MainActivity 的点击微调的C>你的设置片段，创建一个包和设置此值的片段里面的SelectItem 方法如下：

First (in MainActivity) = get the value of the clicked spinner from MainActivity to your setting Fragment, create a Bundle and set this value to the fragment inside SelectItem method as follows:

switch(...) {
    case 2: 
        frag = new Menu();
        // get the value of the spinner selected from here! Something like this:
          String text = ((Spinner) findViewById(R.id.spinnerSetting)). getSelectedItem().toString();
        // String named "spinner_position", this is how you can get it after
        args.putString("spinner_position", text);
        break;
    ...
}
frag.setArguments(args);
// replace the fragment  

二（在菜单的）=接受这种说法如下：

Second (in Menu) = receive this argument as follows:

// receive using the name "spinner_position", that's it. Nothing else.
String text_spinner = getArguments().getString("spinner_position");
