La imagen seleccionada no se muestra en mainActivity

¿Por qué la imagen seleccionada no se muestra en Claims.java ? ¿Me he perdido algo?

            c.moveToFirst();
            int columnIndex = c.getColumnIndex(filePath[0]);
            String picturePath = c.getString(columnIndex);
            if(picturePath.startsWith("/")) picturePath = picturePath.substring(1);

            Drawable d = new BitmapDrawable(thumbnail);
            viewImage.setBackground(d);
        }
    }
}

Cuando selecciono la imagen, no imageviewe nada en imageviewe . Pero si capturo la Imagen desde la cámara, la imagen puede mostrar ... ¿Por qué?

10-22 14:28:11.128    7451-7451/com.example.project.project E/ViewRootImpl﹕ sendUserActionEvent() mView == null
10-22 14:28:15.228    7451-7451/com.example.project.project E/BitmapFactory﹕ Unable to decode stream: java.io.FileNotFoundException: /https:/lh3.googleusercontent.com/-ZiYOXTFTKqQ/URcxPqvEtTI/AAAAAAAAAJw/GN893VrnxGw/I/PANO_20130210_133321.jpg: open failed: ENOENT (No such file or directory)

¿Qué significa esto? ¿Cómo puedo arreglar esto? ¿Y cómo puedo saber la versión de sdk en el android studio ? Por favor, ayúdame ... Gracias

Answer 1

Como puedo ver en tu logcat, tu camino está equivocado.

Hay un "/" adicional al comienzo.

Puedes probar:

if(picturePath.startsWith("/")) picturePath = picturePath.substring(1);

Answer 2

Hola, yo también estoy enfrentando el mismo problema y me gustó esto ...

String[] filePathColumn = {MediaStore.Images.Media.DATA};
            Cursor cursor = getActivity().getContentResolver().query(data.getData(),
                    filePathColumn, null, null, null);
            cursor.moveToFirst();
            int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
            String imgDecodableString = cursor.getString(columnIndex);
            cursor.close();

            viewImage.setImageBitmap(BitmapFactory
                    .decodeFile(imgDecodableString));

simplemente reemplaza el código en else if (requestCode == 2) con el código mencionado anteriormente

Espero que esto solucione tu problema

Answer 3

Me enfrenté a esto antes y me gustó esto

else if (requestCode == 2) {
                Uri selectedImage = data.getData();
               viewImage.setImageURI(selectedImage);

¡y funciona! Espero que te ayude también ... Buena suerte
