一、實現效果：頭部停留 不斷一直保持在頂部

二、實現步驟：

1、匯入Libary：

compile'se.emilsjolander:stickylistheaders:2.7.0'

2、程式碼實現：

package com.example.mac.stickylistheadersdemo;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.AdapterView;
import android.widget.Toast;

import java.util.ArrayList;
import java.util.List;

import se.emilsjolander.stickylistheaders.StickyListHeadersListView;

public class MainActivity extends AppCompatActivity {

    private StickyListHeadersListView stickyListHeadersListView;
    private MainAdapter mainAdapter;
    private List<String> headList;
    private List<String> bodyList;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        //初始化
        stickyListHeadersListView = (StickyListHeadersListView) findViewById(R.id.sl_list);
        mainAdapter = new MainAdapter(this);

        //設定頭部的資料
        headList = new ArrayList<>();
        for (int i = 0; i < 100; i++) {
            headList.add("頭部停留  " + i);
        }
        mainAdapter.setHeadList(headList);

        //設定內容的資料
        bodyList = new ArrayList<>();
        for (int i = 0; i < 100; i++) {
            bodyList.add("內容  " + i);
        }
        mainAdapter.setBodyList(bodyList);

        //設定頭部的點選事件
        stickyListHeadersListView.setOnHeaderClickListener(new StickyListHeadersListView.OnHeaderClickListener() {
            @Override
            public void onHeaderClick(StickyListHeadersListView l, View header, int itemPosition, long headerId, boolean currentlySticky) {
                Toast.makeText(MainActivity.this, "headerId:" + headerId, Toast.LENGTH_SHORT).show();
            }
        });

        //設定內容的點選事件
        stickyListHeadersListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
                Toast.makeText(MainActivity.this, "i:" + i, Toast.LENGTH_SHORT).show();
            }
        });

        //設定頭部改變的監聽
        stickyListHeadersListView.setOnStickyHeaderChangedListener(new StickyListHeadersListView.OnStickyHeaderChangedListener() {
            @Override
            public void onStickyHeaderChanged(StickyListHeadersListView l, View header, int itemPosition, long headerId) {
                Toast.makeText(MainActivity.this, "itemPosition:" + itemPosition, Toast.LENGTH_SHORT).show();
            }
        });

        stickyListHeadersListView.setAdapter(mainAdapter);
    }
}
 

3、介面卡的編寫：

 package com.example.mac.stickylistheadersdemo;

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;

import java.util.List;

import se.emilsjolander.stickylistheaders.StickyListHeadersAdapter;

    /**
     * Created by li on 17-11-20.
     */
    public class MainAdapter extends BaseAdapter implements StickyListHeadersAdapter {

        private Context context;
        private List<String> headList;
        private List<String> bodyList;

        public MainAdapter(Context context, List<String> headList, List<String> bodyList) {
            this.context = context;
            this.headList = headList;
            this.bodyList = bodyList;
        }

        public void setHeadList(List<String> headList) {
            this.headList = headList;
            notifyDataSetChanged();
        }

        public void setBodyList(List<String> bodyList) {
            this.bodyList = bodyList;
            notifyDataSetChanged();
        }

        //設定資料的個數 
        @Override
        public int getCount() {
            return bodyList.size();
        }

        //設定item的條數 
        @Override
        public Object getItem(int i) {
            return bodyList.get(i);
        }

        //獲得相應資料集合中特定位置的資料項 
        @Override
        public long getItemId(int i) {
            return i;
        }

        //(繫結每個條目對應的head的id) 
        @Override
        public long getHeaderId(int position) {
            // return badyList.get(position).headId; //一般寫專案的時候;
            //測試
            if (position < 5) {
                return 0;
            } else if (position < 10) {
                return 1;
            } else if (position < 15) {
                return 2;
            }else {
                return 3;
            }
        }

        //繫結內容的資料
        @Override
        public View getView(int i, View view, ViewGroup viewGroup) {

            BodyHolder bodyHolder = null;
            if (view == null) {
                view = LayoutInflater.from(context).inflate(R.layout.item_body, viewGroup, false);
                bodyHolder = new BodyHolder(view);
                view.setTag(bodyHolder);
            } else {
                bodyHolder = (BodyHolder) view.getTag();
            }
            //設定資料
            bodyHolder.bodyTv.setText(bodyList.get(i));

            return view;
        }

        //繫結頭部的資料
        @Override
        public View getHeaderView(int position, View convertView, ViewGroup parent) {

            HeadHolder headHolder = null;
            if (convertView == null) {
                convertView = LayoutInflater.from(context).inflate(R.layout.item_head, parent, false);
                headHolder = new HeadHolder(convertView);
                convertView.setTag(headHolder);
            } else {
                headHolder = (HeadHolder) convertView.getTag();
            }
            //設定資料
            headHolder.headTv.setText(headList.get(position));

            return convertView;
        }


        //頭部的內部類
        class HeadHolder {
            private TextView headTv;

            public HeadHolder(View itemHeadView) {

                headTv = (TextView) itemHeadView.findViewById(R.id.item_head_tv);
            }
        }

        //內容的內部類
        class BodyHolder {
            private TextView bodyTv;

            public BodyHolder(View itemBodyView) {

                bodyTv = (TextView) itemBodyView.findViewById(R.id.item_body_tv1);
            }
        }

    }
 

    StickyListHeadersListView的用法和listview一致，在佈局檔案的xml就不寫，效果圖是copy過來的，大致差不多。
