I am trying to write a real time pitch visualization using TextureView. The

So, I have created a custom view as ...

Hi All:
I have tried this sample, it works great. But when I change
lockCanvas(null) into lockCanvas(new Rect(x, y, x+20, y+20)), the example
starts to flicker.
It seems 'lockCanvas(Rect)' can not work well for TextureView or any other
reasons?

I will explain and show a

but transormations etc as we know are not supported. So I went to
TextureView. My old code used
The problem is that you are calling updateTexImage() yourself. Do
*not* do this. You are interfering with TextureView, preventing it
from receiving the events that it uses to refresh the screen.
