的Android如何设置相机preVIEW像素
有没有什么办法来设置相机preVIEW像素，喜欢把像素或一些其他的方式？结果
我的要求：我想提出一些像素的相机preVIEW特定位置或将一些点的某些像素值的摄像头preVIEW到另一个值
Is there is any way to set pixels on cameraPreview, like getting pixel or some other ways?
My requirement: I want to put some pixels on a particular positions on camera preview or convert some pixel value of some points in camera preview into another value.
我已经放置在表面观前的自定义视图，每个解决了这个问题， previewCallback 我绘制图像，并设置它作为自定义视图的背景。感觉相机preVIEW绘制像素。 我不知道这是实际的方法，如果我得到最佳的解决方案，我会在这里更新结果
自定义视图
I have solved this issue by placing a custom view in front of the surface view, on each PreviewCallback I draw an image and set it as background of that custom view. It feels drawing pixels on camera preview. I dont know this is the actual method, if I get optimal solution I will update here
Custom view
public class DrawOnTop extends View {
public DrawOnTop(Context context) {
super(context);
// TODO Auto-generated constructor stub
}}
结果
创建摄像头活动器具 previewCallback 结果
要设置自定义查看surfaceview结果
Create camera activity implements PreviewCallback
To set custom view infront of surfaceview
DrawOnTop mDraw = new DrawOnTop(this);
addContentView(mDraw, new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
在上previewFrame ，你可以做code根据preVIEW显示创建图像，并设置图像作为自定义视图的背景。
In onPreviewFrame you can do code for creating image according to preview display and set that image as background of the custom view.
@Override
public void onPreviewFrame(byte[] data, Camera camera) {
//your code
}
