Android中使用TagFlowLayout制作动态添加删除标签

compile 'com.zhy:flowlayout-lib:1.0.3'

private String[] mVals = new String[]
    {"Hello", "Android", "Weclome Hi ", "Button", "TextView", "Hello",
        "Android", "Weclome", "Button ImageView", "TextView", "Helloworld" };
 arrTab = new ArrayList();
  //添加一条数据用于添加标签的替换
  arrTab.add("tab");

//设置adapter
  adapter = new TagAdapter(arrTab){
    @Override
    public View getView(FlowLayout parent, final int position, String s) {
      System.out.println(position + "---" + (arrTab.size() - 1));
      if (position == arrTab.size() - 1){
        //设置最后一个添加标签的布局
        LinearLayout iv = (LinearLayout) LayoutInflater.from(SecondActivity.this).inflate( R.layout.iv,
            mFlowLayout,false);
        //如果点击就添加元素并刷新adapter
        iv.setOnClickListener(new View.OnClickListener() {
          @Override
          public void onClick(View v) {
            int i = arrTab.size() - 1;
            //将新加入的数据加到集合的最后一个位置,而原来的添加图标会到 +1 的位置 
            arrTab.add(i , mVals[position]);
            adapter.notifyDataChanged();
          }
        });
        return iv ;
      }else{
      //正常标签的布局
        RelativeLayout tv = (RelativeLayout) LayoutInflater.from(SecondActivity.this).inflate( R.layout.tv,
            mFlowLayout,false);
        TextView viewById = (TextView) tv.findViewById(R.id.tv_name);
        viewById.setText(s);
        ImageView imageView = (ImageView) tv.findViewById(R.id.iv_delete);
        imageView.setOnClickListener(new View.OnClickListener() {
          @Override
          public void onClick(View v) {
            arrTab.remove(position);
            System.out.println("我点击的是" + position);
