流程布局问题

Question

我正在使用此流布局类在多行中排列动态创建的TextView，但我遇到了以下问题：

1. 此布局的高度不会表现为WRAP_CONTENT（如图所示） 链接中给出的图像）。
2. 我将此布局toRightOf放置为另一个静态 TextViews（，抄送）。它在左边留下一个等于TextView宽度的边距 在每一行（如链接中给出的图像所示）。

我希望在内容切换到下一行时删除此边距。如何解决这个问题？

任何帮助都将不胜感激。



 public class FlowLayout extends ViewGroup 
    {         
        private int paddingHorizontal;   

        public FlowLayout(Context context) 
        {
            super(context);
            init();
        }

        public FlowLayout(Context context, AttributeSet attrs) 
        {
            this(context, attrs, 0);
        }

        public FlowLayout(Context context, AttributeSet attrs, int defStyle) 
        {
            super(context, attrs, defStyle);
            init();
        }

        private void init()
        {
            paddingHorizontal = getResources().getDimensionPixelSize(R.dimen.flowlayout_horizontal_padding);
        }

        @Override
        protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) 
        {
            int childLeft = getPaddingLeft();
            int childTop = getPaddingTop();
            int lineHeight = 0;
            int myWidth = resolveSize(100, widthMeasureSpec);
            int wantedHeight = 0;
            for (int i = 0; i < getChildCount(); i++) 
            {
                final View child = getChildAt(i);
                if (child.getVisibility() == View.GONE) 
                {
                    continue;
                }
                child.measure(getChildMeasureSpec(widthMeasureSpec, 0, child.getLayoutParams().width), getChildMeasureSpec(heightMeasureSpec, 0, child.getLayoutParams().height));
                int childWidth = child.getMeasuredWidth();
                int childHeight = child.getMeasuredHeight();
                lineHeight = Math.max(childHeight, lineHeight);
                if (childWidth + childLeft + getPaddingRight() > myWidth) 
                {
                    childLeft = getPaddingLeft();
                    childTop += lineHeight;
                    lineHeight = childHeight;
                }
                childLeft += childWidth + paddingHorizontal;
            }
            wantedHeight += childTop + lineHeight + getPaddingBottom();
            setMeasuredDimension(myWidth, resolveSize(wantedHeight, heightMeasureSpec));
        }

        @Override
        protected void onLayout(boolean changed, int left, int top, int right, int bottom) 
        {
            int childLeft = getPaddingLeft();
            int childTop = getPaddingTop();
            int lineHeight = 0;
            int myWidth = right - left;
            for (int i = 0; i < getChildCount(); i++) 
            {
                final View child = getChildAt(i);
                if (child.getVisibility() == View.GONE) 
                {
                    continue;
                }
                int childWidth = child.getMeasuredWidth();
                int childHeight = child.getMeasuredHeight();
                lineHeight = Math.max(childHeight, lineHeight);
                if (childWidth + childLeft + getPaddingRight() > myWidth) 
                {
                    childLeft = getPaddingLeft();
                    childTop += lineHeight;
                    lineHeight = childHeight;
                }
                child.layout(childLeft, childTop, childLeft + childWidth, childTop + childHeight);
                childLeft += childWidth + paddingHorizontal;
            }
        }
    }

我在我的xml中使用它：
