游戏移植中粗糙的屏幕分辨率解决方案

  Matrix matrix = new Matrix(); 
        Camera c = new Camera();  
        c.save();     
        //Z引起图片放大缩小
        c.translate(0f, 0f, 2f); //+放大 -缩小   
        c.getMatrix(matrix);       
        c.restore();        

        matrix.preTranslate(centerX, centerY); //centerX,centerY用于移动到屏幕中心  
        matrix.postTranslate(-centerX, -centerY); 
        gameGraphics.canvas.concat(matrix);
