Problems with android camera surfaceView video display

android studio development tools
how does the android camera display range consistent with the range specified by surfaceview? do not wait to display the video range beyond the range specified by surfaceview. Do not show that the video range is only displayed in the range specified by surfaceview. When recording video, the range of recording surfaceview exceeds the range specified by surfaceview. Is there any buddies who do not know about recording?
