动态筛选标签页（类似评论筛选标签）

一个标签选择控件，类似于评价标签，已经实现点击事件选中效果，由于业务需要，我做的是使用ListView展示多个标签控件，并且listview的每个item中只能被选中一项，效果如下图

下面上代码

public class ScreenActivity extends BaseActivity implements View.OnClickListener{    ListView lv_container;    List<RespScreen> list;    WhoAroudApplication application;    Gson gson;    Button btn_affirm;    int checkFragment;    @Override    public void setupViewLayout() {        setContentView(R.layout.activity_screen);        application= (WhoAroudApplication) getApplication();        gson=application.gson;           }    @Override    public void initView() {        lv_container= (ListView) findViewById(R.id.lv_container);        btn_affirm= (Button) findViewById(R.id.btn_affirm);    }    @Override    public void listener() {        btn_affirm.setOnClickListener(this);    }    @Override    public void logicDispose() {           try {                 JSONObject aa=new JSONObject("{\"data\":[{\"title\":\"性别\",\"parameter\":\"sex\",\"content\":[{\"name\":\"不限\",\"value\":-1},{\"name\":\"男\",\"value\":1},{\"name\":\"女\",\"value\":0}]},{\"title\":\"年龄\",\"parameter\":\"age\",\"content\":[{\"name\":\"不限\",\"value\":-1},{\"name\":\"25岁以下\",\"value\":0},{\"name\":\"25-35岁\",\"value\":1},{\"name\":\"35岁以上\",\"value\":2}]},{\"title\":\"距离\",\"parameter\":\"distance\",\"content\":[{\"name\":\"不限\",\"value\":-1},{\"name\":\"5公里\",\"value\":5},{\"name\":\"10公里\",\"value\":10}]},{\"title\":\"认证\",\"parameter\":\"authentication\",\"content\":[{\"name\":\"不限\",\"value\":-1},{\"name\":\"实名认证\",\"value\":3},{\"name\":\"视频认证\",\"value\":4}]},{\"title\":\"类别\",\"parameter\":\"skillTypeid\",\"content\":[{\"name\":\"不限\",\"value\":-1},{\"name\":\"看电影\",\"value\":93},{\"name\":\"k歌\",\"value\":94},{\"name\":\"吃饭\",\"value\":95},{\"name\":\"下午茶\",\"value\":96},{\"name\":\"逛街\",\"value\":97},{\"name\":\"球类\",\"value\":98},{\"name\":\"美容\",\"value\":99},{\"name\":\"健身\",\"value\":100},{\"name\":\"教育\",\"value\":101},{\"name\":\"其它\",\"value\":102}]},{\"title\":\"费用\",\"parameter\":\"cost\",\"content\":[{\"name\":\"不限\",\"value\":-1},{\"name\":\"免费\",\"value\":0},{\"name\":\"收费\",\"value\":1}]}]}");                                    list=gson.fromJson(aa.optString("data"),new TypeToken<ArrayList<RespScreen>>(){}.getType());                 success();                 } catch (JSONException e) {                    e.printStackTrace();                }    }    private void success(){        lv_container.setAdapter(new CommonAdapter<RespScreen>(list,getApplicationContext(),R.layout.item_screen) {            @Override            public void convert(ViewHolderUtils holder, final RespScreen respScreen, int position) {                holder.setText(R.id.tv_tagTitle,respScreen.title!=null?respScreen.title:"");                TagCloudLayout tagCloudLayout=holder.getView(R.id.container);               final TagBaseAdapter mAdapter = new TagBaseAdapter(ScreenActivity.this,respScreen.content);                tagCloudLayout.setAdapter(mAdapter);                tagCloudLayout.setItemClickListener(new TagCloudLayout.TagItemClickListener() {                @Override                public void itemClick(int position) {                    for (int i=0;i<respScreen.content.size();i++){                        respScreen.content.get(i).isCheck=false;                    }                    respScreen.content.get(position).isCheck=true;                    mAdapter.notifyDataSetChanged();            }        });            }        });    }    @Override    public void onClick(View v) {        switch (v.getId()){            case R.id.btn_affirm:                List<CheckScreen> checkScreenList=filtrate();                if (checkScreenList!=null&&checkScreenList.size()>0){

java bean
public class RespScreen implements Serializable{    @Expose    @SerializedName("title")    public String title;    @Expose    @SerializedName("parameter")    public String parameter;    @Expose    @SerializedName("content")    public List<TagBean> content;}

最后说一个CommonAdapter是一个万能adapter，我会在下一篇文章中单独介绍
