Android之解决远程拍照不打开activity用其它方式获取surfaceView

关键代码：

  

   

    

     

    
    

     

      mSurfaceView = new SurfaceView(mContext);
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

      mSurfaceHolder = mSurfaceView.getHolder();
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

      mSurfaceHolder.setType(SurfaceHolder.SURFACETYPE_TYPE_PUSH_BUFFERS）//获取相机缓存数据m
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

      mSurfaceHoler.addCallback(mSurfaceCallback);
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

      mWindowManager = (WindowManager)this.getSystemService(Context.WINOW_SERVICE);
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

      WindowManager.LayoutParams params = new WindowManager.LayoutParams(1,1,WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,0,PixelFormat.UNKNOWN);
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

      mWindowManager.addView(mSurfaceView);
     
    
  
 

注意事项：

  

   

    

     

    
    

     

      mWindowManager.addView(mSurfaceView);之后操作完成之后要记得
     
    
   

    

     

    
    

     

      <pre name="code" class="html">mWindowManager.removeView(mSurfaceView);
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

      <pre name="code" class="html">mSurfaceCallback = new SurfaceHoler.callBack(){
     
    
   

    

     

    
    

     

       public void surfaceCreated(SurfaceHoler holder){
     
    
   

    

     

    
    

     

       initCamera(); 
     
    
   

    

     

    
    

     

       }
     
    
   

    

     

    
    

     

      };
