android 调用摄像头自动拍照 并上传到YEELINK

前几天看到yeelink这个网站很感兴趣，注册了个图像传感器，就想着写个程序调用安卓摄像头并上传照片

程序很简单这个还是记录一下

首先是权限，分别是联网，相机，文件读取，照相和自动对焦的权限

然后是代码段

新建一个类，实现如下接口

照相机必须继承自surfaceview

我是这样调用的。。。。

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

 setContentView(new CameraView(this)); //设置View。。

}

 所以这个程序打开直接就是摄像机画面，自动拍照然后上传 没有任何其他的功能

代码自动分段了貌似，以下代码全在cameraview这个类里面，MyThread是个内部类 

public class CameraView extends SurfaceView implements SurfaceHolder.Callback, Camera.PictureCallback {
    private SurfaceHolder holder;
    private Camera camera;
    private boolean af;
 
    public CameraView(Context context) {//构造函数
        super(context);
 
        holder = getHolder();//生成Surface Holder
        holder.addCallback(this);
 
        holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);//指定Push Buffer
    }
 
    public void surfaceCreated(SurfaceHolder holder) {//Surface生成事件的处理
try {
            camera = Camera.open();//摄像头的初始化
            Camera.Parameters p =camera.getParameters();
            p.setPictureSize(1500, 2000); //设置照片分辨率，太大上传不了
            camera.setParameters(p);
            
            camera.setPreviewDisplay(holder);
            //camera.setDisplayOrientation(90);
        } catch (Exception e) {
        }
    }

private void data2file(byte[] w, String fileName) throws Exception {//将二进制数据转换为文件的函数
        FileOutputStream out =null;
        try {
            out =new FileOutputStream(fileName);
            out.write(w);
            out.close();
        } catch (Exception e) {
            if (out !=null)
                out.close();
            throw e;
        }
    }
 
    @Override
    public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {//Surface改变事件的处理
        Camera.Parameters parameters = camera.getParameters();
        parameters.setPreviewSize(width, height);
        camera.setParameters(parameters);//设置参数
        
        camera.startPreview();//开始预览
       new MyThread().start() ;//这个线程实现拍照保存上传
        //camera.autoFocus(null);
       // camera.takePicture(null, null, this);
    }

class MyThread extends Thread implements PictureCallback{
    	   @Override
    	   public void run() {
    	    super.run();
    	    while(true){
    	    System.out.println("拍照线程wu异常");
    	  camera.autoFocus(null);
    	    camera.takePicture(null, null, this);
    	    try {
				sleep(20000);//20秒执行一次
			} catch (InterruptedException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
    	    }
    	  
    	   }

		@Override
		public void onPictureTaken(byte[] data, Camera camera) {
			// TODO Auto-generated method stub
			try {
	            String path = Environment.getExternalStorageDirectory() +"/test.jpg";
	            Log.v("path", path);
	            data2file(data, path);

	//到这步为止完成了自动拍照并保存，下面这个线程是上传的 想要触摸拍照的话要改写下的onTouchEvent方法，我这不用
