您可以显示设备摄像头的实时输出吗？

Question

I am wondering if it is possible to show the output of the camera running on your device immediately on the screen. Just like the native camera app does.

I have to show the picture, that comes into the camera lens, and additionally add some graphics overlays. That's why I guess, starting an Intent to open the camera activity is not suitable.

I've found some SO Threads, Tutorials and documentation about using the Android Camera API, but they are all able to just take a picture and display it afterwards.

Is it possible at all?

Answer 1

Refer to this link Camera Tutorial for Android (using surfaceview) !

Use the SurfaceView to preview the camera output, then, you can add your graphics overlays as you wish.

Hope this helps :)
