LazyLoad ListView即使用户不启动也会触发onScroll

Question

我有一个动态数据获取VolleyRequest，它被称为onCreate，并将LazyLoading附加到列表视图。但是，在我使用Volley请求获取一些记录之后，也会触发listview onScroll事件。

我尝试了listview的setOnTouchListener并设置了一个布尔变量，但这没有帮助。

setOnTouchListener代码

lstViewPlayers.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View view, MotionEvent motionEvent) {
            if(view == lstViewPlayers && motionEvent.getAction() == MotionEvent.ACTION_SCROLL) {
                userScrolled=true;
            }
            return false;
        }
    });

创建代码

lstViewPlayers=findViewById(R.id.lstViewPlayers);
customAdapterViewUserTeamNew=new CustomAdapterViewUserTeamNew(ViewUsersTeamLive.this,arr_name,arr_playername);
    lstViewPlayers.setAdapter(customAdapterViewUserTeamNew);
if(new ConnectionDetector(ViewUsersTeamLive.this).is_internet_connected()){
        // Index is required to fetch the next set of items
        int startIndex = customAdapterViewUserTeamNew.getCount();
        getUserTeams(startIndex);
    }
    else{
        Toast.makeText(ViewUsersTeamLive.this,"Please connect to working internet",Toast.LENGTH_SHORT).show();
    }

lstViewPlayers.setOnScrollListener(new LazyLoader() {
        @Override
        public void loadMore(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
            // Fetch your data here !!!
            if(new ConnectionDetector(ViewUsersTeamLive.this).is_internet_connected()) {
                if(userScrolled==true) {
                    int startIndex = customAdapterViewUserTeamNew.getCount();
                    getUserTeams(startIndex);
               }
            }
            else{
                Toast.makeText(ViewUsersTeamLive.this,"Please Connect to Working Internet",Toast.LENGTH_SHORT).show();
            }
        }
    });

getUserTeam 函数是截击请求

LazyLoader 类

public abstract class LazyLoader implements AbsListView.OnScrollListener {

private static final int DEFAULT_THRESHOLD = 15 ;

//public static boolean userScrolled=false;

private boolean loading = true  ;
private int previousTotal = 0 ;
private int threshold = DEFAULT_THRESHOLD ;

public LazyLoader() {}

public LazyLoader(int threshold) {
    this.threshold = threshold;
}

@Override
public void onScrollStateChanged(AbsListView view, int scrollState) {
    /*if(scrollState==AbsListView.OnScrollListener.SCROLL_STATE_TOUCH_SCROLL){
        userScrolled=true;
    }
    else{
        userScrolled=false;
    }*/
}

@Override
public void onScroll(AbsListView view, int firstVisibleItem,
                     int visibleItemCount, int totalItemCount) {
    if(loading) {
        if(totalItemCount > previousTotal) {
            // the loading has finished
            loading = false ;
            previousTotal = totalItemCount ;
        }
    }

    // check if the List needs more data
    if(!loading && ((firstVisibleItem + visibleItemCount ) >= (totalItemCount - threshold))) {
        loading = true ;

        // List needs more data. Go fetch !!
        loadMore(view, firstVisibleItem,
                visibleItemCount, totalItemCount);
    }
}

// Called when the user is nearing the end of the ListView
// and the ListView is ready to add more items.
public abstract void loadMore(AbsListView view, int firstVisibleItem,
                              int visibleItemCount, int totalItemCount);

}
