如何將片段添加到導航抽屜菜單項片段

Question

我在這個片段的導航抽屜項目菜單中有一個商店項目片段我想知道如果用戶點擊 Imageview 圖標然后仍然保持我的導航抽屜下面是我的嘗試如何添加另一個片段

package com.example.entertainmentlab.ui.store;

import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;

import androidx.annotation.NonNull;
import androidx.annotation.Nullable;
import androidx.fragment.app.Fragment;
import androidx.fragment.app.FragmentManager;
import androidx.fragment.app.FragmentTransaction;
import androidx.lifecycle.Observer;
import androidx.lifecycle.ViewModelProviders;

import com.example.entertainmentlab.R;
import com.example.entertainmentlab.ui.setting.SettingViewModel;

public class StoreFragment extends Fragment {

    private StoreViewModel StoreViewModel;

    public View onCreateView(@NonNull LayoutInflater inflater,
                             ViewGroup container, Bundle savedInstanceState) {
        StoreViewModel =
                ViewModelProviders.of(this).get(StoreViewModel.class);
        View root = inflater.inflate(R.layout.fragment_store, container, false);
       final ImageView MusicButton = root.findViewById(R.id.music_btn);





     //I want to move to the next Fragment if the user click the music icon

        MusicButton.setOnClickListener(new View.OnClickListener() {
           @Override
           public void onClick(View v) {
               try {

                   Fragment fragment = new BlankFragment();
                   FragmentManager fragmentManager = getActivity().getSupportFragmentManager();
                   FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
                   fragmentTransaction.replace(R.id.nav_store, fragment);
                   fragmentTransaction.addToBackStack(null);
                   fragmentTransaction.commit();
               }catch (Exception e ){
                   Toast.makeText(getActivity(), "erro  "+e, Toast.LENGTH_SHORT).show();
               }
           }
       });
//        StoreViewModel.getText().observe(getViewLifecycleOwner(), new Observer<String>() {
//            @Override
//            public void onChanged(@Nullable String s) {
//                textView.setText(s);
//            }
//        });
        return root;
    }
} 

如果用戶單擊圖像圖標，我想將他/她發送到音樂片段，然后仍然保持抽屜並允許他返回到上一個片段

我建議您使用AlertDialog來完成這項工作，但您可以制作全屏AlertDialog ...
