android-从图库显示图像

Question

I have several images stored in content://media/external/images/media. I would like to display by using ImageView and add the image view to the table. here is my code.

            BitmapFactory.Options options = new BitmapFactory.Options();
            options.inSampleSize = 24;
            final Bitmap b = BitmapFactory.decodeFile("content://media"+getFileLocation(), options);
            ImageView milestoneImageView = new ImageView(this);
            milestoneImageView.setImageBitmap(b);
            recordRow.addView(milestoneImageView);

When I print out the getFileLocation(), it says "/external/images/media/62". So I added "content://media" to make a full path, but it is not working...

Can someone point out why the code above is not working?

Answer 1

I think "/external/images/media/62" its a Uri not a real file path..

So instead of

final Bitmap b = BitmapFactory.decodeFile("content://media"+getFileLocation(), options);

Just try

final Bitmap b = BitmapFactory.decodeStream(getContentResolver().openInputStream("content://media"+getFileLocation()), null,options);

And let me know what happen..
