Bild wird unscharf, wenn die Anzeige von Sdcard in ImageView Android

Question

Ich verwende diesen Code, um Bild von Sdcard in der Bildansicht (im Querformat) anzuzeigen. Aber das Bild verliert seine Qualität und es ist verschwommen.

 File imgFile = new File(imageFile.getAbsolutePath()); // path of your file 

       FileInputStream fis = null; 
       try { 
        fis = new FileInputStream(imgFile); 
       } catch (FileNotFoundException e) 
       { 
        // TODO Auto-generated catch block 
        e.printStackTrace(); 
       } 
       BitmapFactory.Options options = new BitmapFactory.Options(); 
       options.inSampleSize = 8; 
       options.inPurgeable = true; 
       options.inScaled = true; 
       Bitmap bm = BitmapFactory.decodeStream(fis, null,options); 
       profileIV.setImageBitmap(bm); 

Image XML-Datei:

<ImageView 
    android:id="@+id/image11" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:layout_alignParentLeft="true" 
    android:layout_alignParentTop="true"

dies versuchen, denn auch das gleiche Problem, das ich hatte, können Sie die Ausrichtung Teil

 Bitmap bitmap; 
    try { 
     BitmapFactory.Options options = new BitmapFactory.Options(); 
     options.inScaled = false; 
     options.inDither = false; 
     options.inPreferredConfig = Bitmap.Config.ARGB_8888; 

     // down sizing image as it throws OutOfMemory Exception for larger 
     // images 
     //options.inSampleSize = 16; 

     bitmap = BitmapFactory.decodeFile(filePath, options); 
     int orientation = getExifOrientation(filePath); 


     //rotate bitmap 
     Matrix matrix = new Matrix(); 
     matrix.postRotate(orientation); 
     //create new rotated bitmap 
     bitmap = Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), bitmap.getHeight(), matrix, true); 
     ivProfile.setImageBitmap(bitmap); 

    } catch (Exception e) { 
     e.printStackTrace(); 
    } 

public static int getExifOrientation(String filepath) { 
    int degree = 0; 
    ExifInterface exif = null; 
    try { 
     exif = new ExifInterface(filepath); 
    } catch (IOException ex) { 
     ex.printStackTrace(); 
    } 
    if (exif != null) { 
     int orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, -1); 
     if (orientation != -1) { 
      // We only recognise a subset of orientation tag values. 
      switch (orientation) { 
       case ExifInterface.ORIENTATION_ROTATE_90: 
        degree = 90; 
        break; 
       case ExifInterface.ORIENTATION_ROTATE_180: 
        degree = 180; 
        break; 
       case ExifInterface.ORIENTATION_ROTATE_270: 
        degree = 270; 
        break; 
      } 

     } 
    } 

    return degree; 
}
