Question

用户个人资料图片未显示在片段内的“圆形图像视图”中。当用户上传图像时，上传和裁剪图像功能将起作用，并且图像也将被上传到Firebase数据库中。但是它不会显示在用户的个人资料中。

这是上载图像的类的代码：

public class ProfileFragment extends Fragment {

 private CircleImageView mDisplayImage;
 private TextView mName;
 private TextView mStatus;

 private Button mStatusBtn;
 private Button mImageBtn;

 private static final int GALLERY_PICK = 1;

 private StorageReference mImageStorage;
 private ProgressDialog mProgressDialog;


 private DatabaseReference mUserDatabase;
 private FirebaseUser mCurrentUser;

 public ProfileFragment() {}

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

  View view = inflater.inflate(R.layout.fragment_profile, container, false);
  mDisplayImage = (CircleImageView) view.findViewById(R.id.profile_pic);
  mName = (TextView) view.findViewById(R.id.username);
  mStatus = (TextView) view.findViewById(R.id.default_intro);

  mCurrentUser = FirebaseAuth.getInstance().getCurrentUser();

  mUserDatabase = FirebaseDatabase.getInstance().getReference("UsersActivity").child(mCurrentUser.getUid());

  mStatusBtn = (Button) view.findViewById(R.id.settings_status_btn);

  mImageBtn = (Button) view.findViewById(R.id.settings_image_btn);

  mImageStorage = FirebaseStorage.getInstance().getReference();

  String current_uid = mCurrentUser.getUid();

  mUserDatabase = FirebaseDatabase.getInstance().getReference().child("Users").child(current_uid);
  mUserDatabase.keepSynced(true);

  mUserDatabase.addValueEventListener(new ValueEventListener() {
   @Override
   public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
    String name = dataSnapshot.child("name").getValue().toString();
    final String image = dataSnapshot.child("image").getValue().toString();
    String status = dataSnapshot.child("status").getValue().toString();
    String thumb_image = dataSnapshot.child("thumb_image").getValue().toString();

    mName.setText(name);
    mStatus.setText(status);
    if (!image.equals("default")) {
     Picasso.with(getActivity()).load(image).networkPolicy(NetworkPolicy.OFFLINE).placeholder(R.drawable.default_avatar).into(mDisplayImage, new Callback() {


      @Override
      public void onSuccess() {

      }

      @Override
      public void onError() {
       Picasso.with(getActivity()).load(image).placeholder(R.drawable.default_avatar).into(mDisplayImage);
      }


     });
    }
   }

   @Override
   public void onCancelled(@NonNull DatabaseError databaseError) {

   }


  });


  mStatusBtn.setOnClickListener(new View.OnClickListener() {
   @Override

    //Intent status_intent=new Intent(getContext(),StatusActivity.class);

    Intent intent = new Intent(getActivity(), StatusActivity.class);
    intent.putExtra("status_value", status_value);
    startActivity(intent);

   }
  });

  mImageBtn.setOnClickListener(new View.OnClickListener() {
   @Override
   public void onClick(View view) {
    Intent galleryIntent = new Intent();
    galleryIntent.setType("image/*");
    galleryIntent.setAction(Intent.ACTION_GET_CONTENT);

    startActivityForResult(Intent.createChooser(galleryIntent, "SELECT_IMAGE"), GALLERY_PICK);



   }
  });

  return view;
 }


 public void onActivityResult(int requestCode, int resultCode, Intent data) {
  super.onActivityResult(requestCode, resultCode, data);

  if (requestCode == GALLERY_PICK && resultCode == RESULT_OK) {
   Uri imageUri = data.getData();

   CropImage.activity(imageUri)
    .setAspectRatio(1, 1)
    .setMinCropWindowSize(500, 500)

只需尝试一下：

import com.squareup.picasso.Transformation;

public class CircleTransform implements Transformation {
    @Override
    public Bitmap transform(Bitmap source) {
        int size = Math.min(source.getWidth(), source.getHeight());

        int x = (source.getWidth() - size) / 2;
        int y = (source.getHeight() - size) / 2;

        Bitmap squaredBitmap = Bitmap.createBitmap(source, x, y, size, size);
        if (squaredBitmap != source) {
            source.recycle();
        }

        Bitmap bitmap = Bitmap.createBitmap(size, size, source.getConfig());

        Canvas canvas = new Canvas(bitmap);
        Paint paint = new Paint();
        BitmapShader shader = new BitmapShader(squaredBitmap,
                BitmapShader.TileMode.CLAMP, BitmapShader.TileMode.CLAMP);
        paint.setShader(shader);
        paint.setAntiAlias(true);

        float r = size / 2f;
        canvas.drawCircle(r, r, r, paint);

        squaredBitmap.recycle();
        return bitmap;
    }

    @Override
    public String key() {
        return "circle";
    }
}

然后只需将其应用如下：

Picasso.with(activity).load(url).transform(new CircleTransform()).into(ImageView);

但是我更喜欢壁画。
