我有一个包含不同片段的导航抽屉(每个项目显示一个片段),我想将数据从一个片段传递到另一个片段.(我只有一个活动,其中包含一个导航抽屉,其中有一个片段列表). .

我尝试了许多解决方案(捆绑和意图),但无法解决我的问题.

谁能帮助我.

这是我的第一个片段A：

解决方法:

当您在NavigationDrawer内部单击时,可以使用setArguments()方法通过Bundle声明数据,如下所示：

// 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,在您的Fragment内,使用如下所示的getArgument()方法：

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

但是,也许您可​​以在该主题中找到一些有用的提示：Communicating with Other Fragments.

更新：

好吧,我试图从您的代码中举一个例子,但是,这很卑鄙..很难;).

>您不会收到参数,因为在SelectItem方法中,您不会发送带有Menu片段的任何参数(但是您的开关是正确的方式,您的方法是正确的).当您在设置中不发送按钮或任何东西的情况下单击buttonValIDatePrices时,尝试分别尝试发送一个参数,但在另一个捆绑中.刚创建,一个值存储在其中,什么也没有..它与FragmentTransaction没有关系.
>“内部菜单”中,您尝试通过以下方式接收：

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

但我认为使用以下方法会更好：

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

你应该：

首先(在MainActivity中)=将单击的微调器的值从MainActivity获取到您的设置Fragment,创建一个Bundle并将此值设置为SelectItem方法中的fragment,如下所示：

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  

Second(在Menu中)=接收此参数,如下所示：

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