当从相机返回结果时也调用onCreate方法

Question

我正在制作一个可以从相机拍照并在ImageView中加载的应用程序。现在我的问题是当我打开相机，拍照并返回到我的应用程序，然后onCreate方法也会在onActivityResult被调用后被调用。

这个问题在三星的模型中出现。当我在HTC Wildfire上运行这段代码时，一切都很好。在HTC野火onActivityResult被调用，然后onResume被调用。所以我想在HTC野火中可以实现，但在三星s中无法实现。

这是我的代码，

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
         Drawable drawable = null;
         System.out.println("Faces Fond"+facesFound);
         System.out.println("On Activity Result is called");
        switch (requestCode) {
        case Constants.PICK_IMAGE:
            switch(resultCode)
            {
            case RESULT_CANCELED:
                break;
            case RESULT_OK:
                dragLayer.removeAllViews();
                isFaceDetected = false;
                resetArray();
                numberOfViews = 0;
                if(data!=null){
                 uriOfImage = data.getData();
                 System.out.println("Uri is "+ uriOfImage);
                 if(bitmapForDragLayer != null)
                 bitmapForDragLayer.recycle();
                    try {
                        bitmapForDragLayer = BitmapFactory.decodeStream(getContentResolver().openInputStream(uriOfImage));
                         bitmapForDragLayer = Bitmap.createScaledBitmap(bitmapForDragLayer, widthOfBitmap, heightOfBitmap, true);
                    } catch (FileNotFoundException e) {
                        e.printStackTrace();
                    }
                    catch(Exception e){
                        e.printStackTrace();
                    }
                     drawable = new BitmapDrawable(bitmapForDragLayer);
                    dragLayer.setBackgroundDrawable(drawable);
                    isImageLoaded = false;
                    }
                break;
            }
                break;
        case Constants.TAKE_PICTURE_CODE:
            switch(resultCode)
            {
            case RESULT_CANCELED:
                break;
            case RESULT_OK:
                dragLayer.removeAllViews();
                isFaceDetected = false;
                resetArray();
                numberOfViews = 0;
                System.out.println("Value of data"+data);
                if(data!=null){
                bitmapForDragLayer = (Bitmap)data.getExtras().get("data");
                 bitmapForDragLayer = Bitmap.createScaledBitmap(bitmapForDragLayer, widthOfBitmap, heightOfBitmap, true);
                  drawable = new BitmapDrawable(bitmapForDragLayer);
                 dragLayer.setBackgroundDrawable(drawable);
                 isImageLoaded = false;
                }
                 break;
            }
            break;
        case Constants.FRAME_SELECT_CODE:
            currentFrame = frameSelection.getFrameBitmap(resultCode);
            currentSelectedBitmapVO.setSelectedBitmap(selectedFrame);
            selectedFrame = currentFrame;
                    for(int i=0;i<array.size();i++)
                    {
                        System.out.println("value of i"+i);
                        if(array.get(i))
                        {
                        int height = currentBitmapVO[i].getSelectedBitmapHeight();
                        int width  = currentBitmapVO[i].getSelectedBitmapWidth();
                        Bitmap b = Bitmap.createScaledBitmap(currentFrame, width, height, true);
                        selectedFrame = b;
                        imageView[i].setImageBitmap(selectedFrame);
                        imageView[i].invalidate();
                        }
                    }
                break;
        }
 }

这是调用相机拍照的代码。

Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, Constants.TAKE_PICTURE_CODE);

相同的代码在HTC运行良好，但在三星不运行。

也许你的应用程序在拍照时因为内存不足而被系统杀死了。然后活动生命周期将重新开始，onCreate()
