Android - สอบถามเกี่ยวกับ startActivityForResult ใน Tab Widget หน่อยคับ

Intent   intent3  = new Intent().setClass(this, Class3.class);		// เรียกไปหน้าที่แสดงรูป 
    	spec = oth.newTabSpec(tTab3).setIndicator(tTab3) .setContent(intent3);
    	oth.addTab(spec);

	public void displayPict(View v) { // กดปุ่ม Button จะไป Browse รูปในเครื่อง
		
		Intent itn = new Intent(Intent.ACTION_PICK,
				android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI);
		startActivityForResult( itn, SELECT_IMAGE);
	
	}	

@Override
	protected void onActivityResult(int requestCode, int resultCode, Intent data){

		super.onActivityResult(requestCode, resultCode, data); // รูปที่คลิกได้จากการ Browse จะต้องมาแสดงใน ImageView
		
		if (requestCode == SELECT_IMAGE && resultCode == RESULT_OK 
					&& data != null) {
			Uri selectedImage = data.getData();
			data.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);	 
			
			Log.d(TAG, "uri " + selectedImage);
			
			String [] filePathColumn = { MediaStore.Images.Media.DATA };
			Log.d(TAG, "filePathcolumn " + filePathColumn);
			
			Cursor cursor = getContentResolver().query(selectedImage,
										filePathColumn, null, null, null);
			cursor.moveToFirst();
			
			int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
			
			Log.d(TAG, "cursor " + cursor + " col index " + columnIndex);
			
			String pathfile = cursor.getString(columnIndex);
			
			Log.d(TAG, "pic path " + pathfile);
			
			cursor.close();
			
			int width = ImagesView.getWidth();	
			int height = ImagesView.getHeight();
			BitmapFactory.Options factoryOptions = new BitmapFactory.Options();
			factoryOptions.inJustDecodeBounds = true;
			
			BitmapFactory.decodeFile(pathfile, factoryOptions);

			int imageWidth = factoryOptions.outWidth;
			int imageHeight = factoryOptions.outHeight;
		    Log.d(TAG, "w h of photo " + imageWidth + "x"+ imageHeight);
		
			int scaleFactor = Math.min(imageWidth/width, imageHeight/height);
			Log.d(TAG, "scale  " + scaleFactor);
			factoryOptions.inJustDecodeBounds = false;
			factoryOptions.inSampleSize = scaleFactor;
			factoryOptions.inPurgeable = true;
	
			Bitmap bitmap = BitmapFactory.decodeFile(pathfile,
									factoryOptions);
			ImagesView.setImageBitmap(bitmap);
		}
