点击按钮时，将一个Fragment切换到另一个Fragment

Question

我已经学会了如何在按钮点击时从一个片段活动更改到另一个（所有都是片段活动），但现在我在同一片段上有多个按钮的问题。只有第一个按钮ID有效。我有多个按钮，每个按钮都有不同的片段活动。需要帮助。

package com.test.fragmentation;

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentTransaction;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;

public class List extends Fragment {


    public List() {
        // Required empty public constructor
    }


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        View rootView = inflater.inflate(R.layout.fragment_list, container, false);


        Button ID = (Button) rootView.findViewById(R.id.btnHello);
        ID.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    FragmentManager fragmentManager = getFragmentManager();
                    FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
                    HelloFragment NAME = new HelloFragment();
                    fragmentTransaction.replace(R.id.fragment_container, NAME);
                    fragmentTransaction.commit();

                }
            });
        return rootView;
    }
}

更改片段名称为想要移动的名称

Button ID = (Button) rootView.findViewById(R.id.btnHello);
            ID.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View view) {
                        FragmentManager fragmentManager = getFragmentManager();
                        FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
                        HelloFragment NAME = new HelloFragment();
                        fragmentTransaction.replace(R.id.fragment_container, NAME);
                        fragmentTransaction.commit();

                    }
                });

在按钮点击时更改片段名称：

ABC NAME = new ABC ();

Button ID = (Button) rootView.findViewById(R.id.btnHello);
            ID.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View view) {
                       FragmentName Name = new FragmentName ();//Name of fragment where you want to go. 

FragmentTransaction fragmentTransaction= 

getActivity().getSupportFragmentManager().beginTransaction();  

fragmentTransaction.replace(R.id.frame, Name);              

fragmentTransaction.commitAllowingStateLoss();

                    }
                });

@Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View v = inflater.inflate(R.layout.fragment_profile, container, false); notification = (Button)v.findViewById(R.id.notification);

@Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View v = inflater.inflate(R.layout.fragment_profile, container, false); notification = (Button)v.findViewById(R.id.notification);

    notification.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            FragmentTransaction fr = getFragmentManager().beginTransaction();
            fr.replace(R.id.container(this is the main activity container layout),new NotificationFragment(this is the fragment you want to go)());
            fr.commit();
        }
    });

    return v;
}
