我想显示从我的SD卡为.jpg到我的布局中的ImageView。我没有得到任何错误，但没有得到显示。我想AP preciate任何帮助。谢谢

编辑：

 布局1 =（的LinearLayout）findViewById（R.id.layout1Activity）;     串imgFile = Environment.getExternalStorageDirectory（）+/Apple.jpg;            位图MYBITMAP = BitmapFactory.de codeFILE（imgFile）;            ImageView的MYIMAGE =新ImageView的（本）;            myImage.setImageBitmap（MYBITMAP）;            layout1.addView（MYIMAGE）; 

解决方案

不直接访问SD卡，尝试访问它槽环境。像这样的：

 字符串IMAGEDIR = Environment.getExternalStorageDirectory（）+/ apple.jpg; 

，然后你可以叫 BitmapFactory ：

 位图MYBITMAP = BitmapFactory.de codeFILE（IMAGEDIR）; 

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);

解决方案

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);
