Question

当我编辑个人资料图片并将其正确保存在片段中时，但我必须找到获取导航标题个人资料图片的方式来更新与我的片段相同的个人资料图片。打开导航抽屉时，我需要自动刷新导航标题中的个人资料图片。我找到1个参考，但是没有明确的程序和说明。

布局正在发生的图像

您可以在片段中引用导航视图的属性。在ProfileFragment.java Firebase侦听器中进行以下更改。

ref.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>(){
                @Override
                public void onSuccess(Uri uri){


                    Toast.makeText(getApplicationContext(),"Image Loaded",Toast.LENGTH_SHORT).show();

                    //declare a global variable to contain the uri to 
                    //set in the drawable listener
                    globalDeclaredUri = uri;

                }
            });

ProfileFragment.java onCreate应该正在侦听抽屉活动。确保getActivity不为null。

@Override
protected void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_admin_);

    storage=FirebaseStorage.getInstance();
    storageReference=storage.getReference();

    //your codes continues...

   NavigationView navigationView =(NavigationView)getActivity().findViewById(R.id.nav_view);
   View parentView = navigationView.getHeaderView(0);
   ImageView navProfilePic = parentView.findViewById(R.id.admin_nav_imageView);

   DrawerLayout mDrawerLayout = (DrawerLayout) getActivity().findViewById(R.id.drawer_layout);                    

    NavigationView navigationView = (NavigationView) getActivity().findViewById(R.id.nav_view);
    final View parentView = navigationView.getHeaderView(0);
    final ImageView navProfilePic = parentView.findViewById(R.id.img_header_bg);

    DrawerLayout mDrawerLayout = (DrawerLayout) getActivity().findViewById(R.id.drawer_layout);

    mDrawerLayout.addDrawerListener(new DrawerLayout.DrawerListener() {
        @Override
        public void onDrawerSlide(View drawerView, float slideOffset) {

        }

        @Override
        public void onDrawerOpened(View drawerView) {

        }

        @Override
        public void onDrawerClosed(View drawerView) {

        }

        @Override
        public void onDrawerStateChanged(int newState) {
            Picasso.get()
                       .load(globalDeclaredUri)
                       .resize(250,250)
                       .into(navProfilePic);
        }
    });
}
