使用按钮单击

Question

我有一组片段。其中一个片段有一个自定义的AlertDialog，顶部有一个取消按钮。我希望关闭按钮关闭AlertDialog框并转到主页片段，但我不知道如何实现并收到此错误：

  

java.lang.IllegalArgumentException：找不到片段HomeFragment {e0d925e＃4 id = 0x7f0c0093}

的id 0x7f0c0093（design.material.instagrammockup：id / frags）的视图

请帮忙。以下是我现在的情况：

public class CameraFragment extends Fragment  {
 TabLayout tabLayout;
 View rootView ;
 Context context;
 AlertDialog.Builder alertDialog = null;
 ImageButton closebutton;

@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
}

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

    rootView = inflater.inflate(R.layout.camera_fragment, container,false);
   /* ImageView imageView =(ImageView) rootView.findViewById(R.id.hold_Capture_image);
    imageView.setImageResource(R.drawable.beyonce);
   */ //GET THE VIEW PAGER AND SET ITS PAGER ADAPTER SO THAT IT CAN DISPLAY ITEMS
    final ViewPager camera_viewPager =(ViewPager)rootView.findViewById(R.id.camera_viewPager);
    PagerAdapter pagerAdapter = new PagerAdapter(getActivity().getSupportFragmentManager(), getActivity());
    camera_viewPager.setAdapter(pagerAdapter);
     alertDialog = new AlertDialog.Builder(getActivity(),R.style.AlertDialog);
    alertDialog.setCancelable(false);
    LayoutInflater layoutInflater = LayoutInflater.from(getActivity());
    View view = layoutInflater.inflate(R.layout.camera_image_holder,null);
    ImageView imageView =(ImageView) view.findViewById(R.id.hold_Capture_image);
    closebutton =(ImageButton) view.findViewById(R.id.closeButton);
    Button gallery =(Button) view.findViewById(R.id.galleryButton);
    Button photo =(Button) view.findViewById(R.id.cameraButton);
    Button video =(Button) view.findViewById(R.id.videoButton);
    alertDialog.setView(view);
    alertDialog.show();


    closebutton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Fragment frags = new HomeFragment();
            FragmentManager fragmentManager = getFragmentManager();
            FragmentTransaction transaction = fragmentManager.beginTransaction();
            transaction.replace(R.id.frags,frags);
            transaction.commit();
        }
    });

    //GIVE THE TAB LAYOUT THE VIEW PAGER
    tabLayout =(TabLayout)rootView.findViewById(R.id.camera_tabs);
    tabLayout.setupWithViewPager(camera_viewPager);
    camera_viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
    tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
        @Override
        public void onTabSelected(TabLayout.Tab tab) {
            camera_viewPager.setCurrentItem(tab.getPosition());
        }

        @Override
        public void onTabUnselected(TabLayout.Tab tab) {

        }

        @Override
        public void onTabReselected(TabLayout.Tab tab) {

        }
    });
    return rootView;
}


class PagerAdapter extends FragmentPagerAdapter {
    Context context;
    public PagerAdapter(FragmentManager fm, Context context) {
        super(fm);
        this.context = context;
    }

    @Override
    public Fragment getItem(int position) {
        return null;
    }

    @Override
    public int getCount() {
        return 0;
    }
}

@Override
public void onDestroyView() {
    super.onDestroyView();
    if (rootView != null) {
        ViewGroup parentViewGroup = (ViewGroup) rootView.getParent();
        if (parentViewGroup != null) {
            parentViewGroup.removeAllViews();
        }
    }

}
}
