Android相机Flash预览

Question

我的问题是下面的一个，我想要拍一张照片，但是我需要先打开相机，然后拍照然后关闭。

CameraPreview.flashTurnOff（）是 void ，新的Timer（）。计划参数是 task，int 。

如何将无效 CameraPreview.flashTurnOff（）转换为任务？谢谢！

captureButton.setOnClickListener(new View.OnClickListener() //TAKE THE PICTURE
    {        
        @Override        
        public void onClick(View v) 
        {            
            if(isFlashOn == 1)
            {
                CameraPreview.flashTurnOn();
                new Timer().schedule(CameraPreview.flashTurnOff(), 1000);
                mCamera.takePicture(null, null, mPicture);
            }
            else
            {    
                mCamera.takePicture(null, null, mPicture);  
                Log.d(TAG, "Tirou foto");
            }
        }    
    });
}

**That was the solution.**

class DesligaFlash extends Thread 
    {
        public void run()
        {
            try 
            {
                super.sleep(1000);
            } 
            catch (InterruptedException e) 
            {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            CameraPreview.flashTurnOff();
        }
    }

captureButton.setOnClickListener(new View.OnClickListener() //TAKE THE PICTURE
    {        
        @Override        
        public void onClick(View v) 
        {            
            if(isFlashOn == 1)
            {
                CameraPreview.flashTurnOn();
                DesligaFlash bagulho = new DesligaFlash();
                bagulho.run();
            }
            mCamera.takePicture(null, null, mPicture); 
        }   
    });
