- byte [] mPixel = new byte[240*320*2];
- int n = 0;
- ByteBuffer buffer = ByteBuffer.wrap( mPixel );/*将 byte 数组包装到缓冲区中*/
- Bitmap VideoBit = Bitmap.createBitmap(240, 320, Config.RGB_565); /*位图文件 */
- fileIS = new FileInputStream(PathFileName);
- fileIS.read(mPixel);
- protected void onDraw(Canvas canvas) {
- super.onDraw(canvas);
- VideoBit.copyPixelsFromBuffer(buffer); /*从缓冲区中复制像素，从当前位置开始覆盖位图的像素*/
- canvas.drawBitmap(VideoBit, 0, 0, null); ｝
