La imagen seleccionada no se muestra en mainActivity

Question

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

}
}
}

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
