毕加索没有从画廊加载图像

Question

I've tried every answer I've found for this issue without success. My users choose an image from their gallery to be displayed in an ImageView using Picasso, but it never get's loaded into the imageview.

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode,resultCode,data);
    if(resultCode == RESULT_OK){
        if(requestCode == SELECT_PICTURE){

            String selectedImageURI = data.getData().getPath();
            File imageData = new File(String.valueOf(selectedImageURI));
            //selectedImagePath = getPath(selectedImageURI);

            if(!image1_exists){
                Picasso.with(MemoriesActivity.this).load(imageData).noPlaceholder().centerCrop().fit().into(image1);
            }
            else if(!image2_exists){
                //This is executed
                Picasso.with(MemoriesActivity.this).load(imageData).noPlaceholder().centerCrop().fit().into(image2);
            }
            else if(!image3_exists){
                //Picasso.with(MemoriesActivity.this).load(imageData).centerCrop().fit().into(image3);
            }
        }

    }
}

public void addPhoto(View v){

    Intent intent = new Intent();
    intent.setType("image/*");
    intent.setAction(Intent.ACTION_GET_CONTENT);
    startActivityForResult(Intent.createChooser(intent,"Select Picture"), SELECT_PICTURE);

}

I can't find any explainable cause for this except something must be wrong with onActivityResult together with Picasso, because I load images using exactly the same Picasso build/method when fetching images from my backend.

EDIT SOLUTION

public void attachImage(Uri uri, int imageIndex) {

    BitmapFactory.Options options = new BitmapFactory.Options();
    options.inSampleSize = 0;

    InputStream stream;
    try {

        stream = getContentResolver().openInputStream(uri);

        Bitmap bitmap = BitmapFactory.decodeStream(stream);
        Bitmap image_scaled = Bitmap.createScaledBitmap(bitmap, 800, 800 * bitmap.getHeight() / bitmap.getWidth(), false);


        if (imageIndex == 0) {
            uploadImage(image_scaled, "image1");
            handler.get(imageIndex).loadImageFromUri(this,(ImageView) findViewById(R.id.image1),uri);
            handler.get(imageIndex).loadEnlargedImageFromUri(this,image1_full,uri);
        }

    } catch (FileNotFoundException e) {
        e.printStackTrace();
    }

}

So I created that method (it's under construction, but the solution remains the same) and calls it like this in onActivityResult :

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == RESULT_OK) {
        if (requestCode == SELECT_PICTURE) {

            Uri selectedImage = data.getData();

            int imageIndex = getFirstNonExistingImage();

            if (imageIndex == 0) {
                attachImage(selectedImage,imageIndex);
            }

        }

    }
}

I load the URI with a custom Picasso class (handler.loadImageFromUri), but same principle.

Answer 1

Solved by creating an external method and executing that inside onActivityResult instead. No idea why, but it worked.

Answer 2

get real path from URI and set it to Picasso.

 Uri selectedImage = data.getData();

 imagePath = getRealPathFromURI(this, selectedImage);

 public String getRealPathFromURI(Context context, Uri contentUri) {

 Cursor cursor = null;

 try {

  String[] proj = {MediaStore.Images.Media.DATA};

   cursor = context.getContentResolver().query(contentUri, proj, null, null, null);
        int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToFirst();
        return cursor.getString(column_index);
    } finally {
        if (cursor != null) {
            cursor.close();
        }
    }
}

Answer 3

You dont need to make cursor query with picasso.

With picasso you just need to write one line of code I have extended it for better understanding :-

           //Get image Uri
            Uri selectedImageURI = data.getData();

            //Load image from picked Uri
Picasso.with(MainActivity1.this).load(selectedImageURI).noPlaceholder().centerCrop().fit()
                    .into((ImageView) findViewById(R.id.imageView1));
