Android: Displaying .jpg image from sdcard using ImageView

问题

I am trying to display a .jpg from my sd card into an imageview in my layout. I dont get any errors, but nothing gets displayed. I would appreciate any help. Thanks

EDIT:

        layout1 = (LinearLayout) findViewById(R.id.layout1Activity);

     String imgFile = Environment.getExternalStorageDirectory() + "/Apple.jpg";


            Bitmap myBitmap = BitmapFactory.decodeFile(imgFile);


            ImageView myImage = new ImageView(this);
            myImage.setImageBitmap(myBitmap);
            layout1.addView(myImage);

回答1:

do NOT access the SD card directly, try accessing it trough Environment. Like this:

String imageDir = Environment.getExternalStorageDirectory()+"/apple.jpg";

and then you can call BitmapFactory:

Bitmap myBitmap = BitmapFactory.decodeFile(imageDir);
