java - Read Byte Array from surface view?

Question

Is is possible to read byte array from surface view?

Like in Camera API we have callback from setPreviewCallback() here in onPreviewFrame(byte[])

we have access of byte array. So same like can we have something directly from SurfaceView?

Answer 1

或许答案稍后会来。

PixelCopy可以byte[]从Surface

以下是一些示例：

mBitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);

PixelCopy.request(mSurface, // which you wanna get byte[]
     mBitmap, // the byte[] in Bitmap
     mCallback,
     mHandler // which Callback will be invoke
);

在Callback你可以得到 byte[] from Bitmap，就像Bitmap.copyPixelsToBuffer(...)
