参照web flex实现的布局方式。值得学习一下。前段时间的标签云确实有点小问题，flex很好的解决了它.

  // 通过代码向FlexboxLayout添加View
        TextView textView = new TextView(this);
        textView.setText("TestLabel");
        textView.setGravity(Gravity.CENTER);
        textView.setBackgroundResource(R.drawable.label_bg_shape);
        textView.setPadding(DensityUtil.dip2px(mContext,15),0,DensityUtil.dip2px(mContext,15),0);
        textView.setTextColor(getResources().getColor(R.color.text_color));
        textView.setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,DensityUtil.dip2px(mContext,40)));
        flexboxLayout.addView(textView);
        //通过FlexboxLayout.LayoutParams 设置子元素支持的属性
//        ViewGroup.LayoutParams params = textView.getLayoutParams();
//        if(params instanceof FlexboxLayout.LayoutParams){
//            FlexboxLayout.LayoutParams layoutParams = (FlexboxLayout.LayoutParams) params;
//            layoutParams.setFlexBasisPercent(0.5f);
//        }
