android - 如何从Android中的另一个 fragment 调用一个 fragment 类方法

嗨，我对我的应用程序中的android非常陌生，我创建了两个片段，分别是“ MenuFragment”和“ TextFragment”好的

但是在我的TextFragment中我有一个方法，因此我想从我的MenuFragment类中调用该方法

我想从我的MenuFragment调用的public void change（String txt，String txt1）方法

我该怎么做请帮我一些

文字片段：-

public class TextFragment extends Fragment {
    TextView text,vers;

    @Override

    public View onCreateView(LayoutInflater inflater,ViewGroup container, Bundle savedInstanceState) {

        return view;
    }

    public void change(String txt, String txt1){

        text.setText(txt);
        vers.setText(txt1);
    }
}

MenuFragment：-

public class MenuFragment extends Fragment {

    String[] AndroidOS = new String[]{"Cupcake", "Donut", "Eclair", "Froyo", "Gingerbread", "Honeycomb", "Ice Cream SandWich", "Jelly Bean", "KitKat", "Jelly Bean", "KitKat"};
    String[] Version = new String[]{"1.5", "1.6", "2.0-2.1", "2.2", "2.3", "3.0-3.2", "4.0", "4.1-4.3", "4.4", "4.1-4.3", "4.4"};

  @Override
    public void onListItemClick(ListView l, View v, int position, long id) {

    }
}

最佳答案

你可以试试看

对于TextFragment：-

public class TextFragment  extends Fragment{

public static TextView text,vers;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    return super.onCreateView(inflater, container, savedInstanceState);
}

public static void change(String txt, String txt1){

    text.setText(txt);
    vers.setText(txt1);
}
}

对于MenuFragment：-

public class MenuFragment extends Fragment {

ListView list;
Button button1, button2;
String[] AndroidOS = new String[]{"Cupcake", "Donut", "Eclair", "Froyo", "Gingerbread", "Honeycomb", "Ice Cream SandWich", "Jelly Bean", "KitKat", "Jelly Bean", "KitKat"};
String[] Version = new String[]{"1.5", "1.6", "2.0-2.1", "2.2", "2.3", "3.0-3.2", "4.0", "4.1-4.3", "4.4", "4.1-4.3", "4.4"};


  @Override
public void onListItemClick(ListView l, View v, int position, long id) {
         TextFragment.change(AndroidOS[position],Version[position]);
}
}

希望对您有所帮助。谢谢
