代码： imagearray是String的数组。 

          ParcelFileDescriptor fd;
         Uri imageUri2=Uri.parse(imagearray[1]);

        try {
            fd = getContentResolver().openFileDescriptor(imageUri2, "r");
        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
          Bitmap bmp2 = BitmapFactory.decodeFileDescriptor(fd.getFileDescriptor());
          Bitmap resized2 = Bitmap.createScaledBitmap(bmp2, 100, 100, true);
           Bitmap conv_bm2 = ImageCropScale.getRoundedRectBitmap(resized2, 100);

          ib2.setImageBitmap(conv_bm2);

答案 0 :(得分：1)

请试试这个。 在 AndroidManifest.xml 文件中添加 READ_EXTERNAL_STORAGE 权限

<uses-permission  android:name="android.permission.READ_EXTERNAL_STORAGE"/>

答案 1 :(得分：0)

在项目的Androidmanifest文件中添加此权限，位于应用程序标记

的正上方 
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

要写入外部存储，您确实必须在清单中声明这一点。另请参阅http://developer.android.com/reference/android/Manifest.permission.html以详细了解权限及其所需的原因。
