title: Given a path of an image, how to display the image contented in that path
body: <p>I saved a path of an image taken by the camera into sqlite DB as the following:
  retrievePath() method is to retrieve the saved path from the DB.</p>
  
  <p><code>getImageUri(imgPath)</code> method is to cobvert the file path into uri.</p>
  
  <pre><code>OnClickListener btn_TakePictureListener = new OnClickListener() {
  
  @Override
  public void onClick(View v) {
          // TODO Auto-generated method stub
          Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
          File imgPath = retrievePath();
          intent.putExtra(MediaStore.EXTRA_OUTPUT, getImageUri(imgPath));
          startActivityForResult(intent, RequestCode);
      }
  };
  
      private File retrievePath() {
      int []x = imgOpHlpr.getIDs();
      String s = imgOpHlpr.getImg_Path(x.length);
      File file = new File(s);
      Toast.makeText(getApplicationContext(), "retrieved path "+s.toString(),    
      Toast.LENGTH_LONG).show();
      return file;            
  }   
  
  private Uri getImageUri(File path) {
      Uri imgFileUri = Uri.fromFile(path);
      return imgFileUri;
  }
  </code></pre>
  
  <p>and what i want to know now is: after retrieving the path from the DB, how to display the contents of that path in an imageView. in other words, ofcourse the path of the image contains data, i want to display the contented data inside an <code>ImageView</code>.</p>
  
  <p>How to do so?</p>
