Android中使用TagFlowLayout制作动态添加删除标签

效果图

简单的效果图(使用开源库)[flowlayout](“ https://github.com/hongyangandroid/flowlayout “)

步骤

导包

compile 'com.zhy:flowlayout-lib:1.0.3'
<com.zhy.view.flowlayout.tagflowlayout
  android:id="@+id/id_flowlayout"
  zhy:max_select="-1"
  android:layout_width="fill_parent"
  android:layout_height="wrap_content"
  android:padding="20dp">
</com.zhy.view.flowlayout.tagflowlayout>

初始化数据

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tagflowlayout的adapter

//设置adapter
  adapter = new tagadapter<string>(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);
            adapter.notifydatachanged();
          }
        });
        return tv;
      }
    }
  };
  mflowlayout.setadapter(adapter);

各种布局文件

iv
<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="88dp"
android:paddingtop="5dp"
android:layout_height="40dp">
<imageview
  android:layout_gravity="center"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:background="@drawable/bacs_btn_addbq"
  />
  </linearlayout>
tv
<relativelayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="88dp"
android:layout_height="wrap_content">
<!--android:background="@drawable/tag_bg"-->
<textview
  android:id="@+id/tv_name"
  android:layout_margintop="7dp"
   android:layout_width="80dp"
  android:gravity="center"
   android:layout_height="32dp"
  android:background="@drawable/bg_tv"
   android:text="我是唯爱"
  android:textsize="13sp"
   android:textcolor="#fff">
</textview>
<imageview
  android:id="@+id/iv_delete"
  android:layout_alignparentright="true"
  android:layout_width="15dp"
  android:layout_height="15dp"
  android:src="@drawable/sm_ico_sounddel"
  />
</relativelayout>
