Using FrameLayout to fix the size issue

mPreviewSize=getOptimalPreviewSize(supportedPreviewSizes, targetRatio);
        double ratio=(double)mPreviewSize.width/mPreviewSize.height;
        //Log.d(TAG,"Target ratio: "+targetRatio);
        Log.d(TAG, "Ratio: "+ratio);
        int new_width=0, new_height=0;
        if((double)previewFrame.getWidth()/previewFrame.getHeight()<ratio)
        {
            new_width=(int)(Math.round(previewFrame.getHeight()*ratio));
            new_height=mPreviewSize.height;
        }
        else
        {
            new_width=mPreviewSize.width;
            new_height=(int)Math.round((double)new_width/ratio);
        }
        previewFrame.setLayoutParams(new FrameLayout.LayoutParams(new_width, new_height));
