首先自定義一個ScrollView 

package one.bw.com.jingdong.sousuo.view;

import android.content.Context;
import android.util.AttributeSet;
import android.util.Log;
import android.widget.ScrollView;

import one.bw.com.jingdong.sousuo.inerts.ScrollViewListener;

/**
 * Created by Administrator on 2017/12/13/013.
 */
public class 
 
MyScrollView extends ScrollView {

//定義一個介面的物件
    private ScrollViewListener scrollViewListener = null;

    public MyScrollView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }
//對外提供介面回撥的方法
    public void setScrollViewListener(ScrollViewListener scrollViewListener) {
        this
 
.scrollViewListener = scrollViewListener;
    }

    @Override
protected void onScrollChanged(int l, int t, int oldl, int oldt) {
        super.onScrollChanged(l, t, oldl, oldt);
        //scrollview的起始點+總高度==crollView的computeVerticalScrollRange
if(getScrollY() + getHeight() ==  computeVerticalScrollRange())
        {
            Log.d
 
("jiaba","------滾動到最下方------");
            if(scrollViewListener!=null){
                scrollViewListener.onScrollChanged(this, l, t, oldl, oldt);
            }
        }
    }
}

在做一個介面的回撥，傳值

package one.bw.com.jingdong.sousuo.inerts;

import one.bw.com.jingdong.sousuo.view.MyScrollView;

/**
 * Created by Administrator on 2017/12/13/013.
 */
public interface ScrollViewListener {
    void onScrollChanged(MyScrollView context, int x, int y, int oldx, int oldy);
}

最後activity中的程式碼，，

//上拉載入資料
souxiangScrollView.setScrollViewListener(new ScrollViewListener() {
            @Override
public void onScrollChanged(MyScrollView context, int x, int y, int oldx, int oldy) {
//                Toast.makeText(MySouSuoShow.this,"正在載入。。。",Toast.LENGTH_SHORT).show();
try {
                    Thread.sleep(1000);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                List<MySouXiangBean.DataBean> data = mySouXiangBean.getData();
                list.addAll(data);

setAdapter();

}
