博客展示了一段Android开发的代码，包含在`onLayout`方法中对视图进行布局的逻辑，通过循环遍历子视图，根据视图的宽高和可用宽度进行布局调整，还包含`onMeasure`方法对视图测量的操作。

int width = getWidth();
        int disWidth = 18;
        int row =0;
        for (int i=0;i<getChildCount();i++){
            View view = getChildAt(i);
            int measuredHeight = view.getMeasuredHeight();
            int measuredWidth = view.getMeasuredWidth();
            if(disWidth+rowmeasuredHeight>width){
                row++;
                disWidth=18;
            }
            view.layout(disWidth,rowmeasuredHeight,measuredWidth+width,measuredHeight*(row+1));
            disWidth+=measuredWidth;
        }
    }

@Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
        measureChildren(widthMeasureSpec,heightMeasureSpec);
    }
