通過(guò)recycleview的setOnScrollListener監(jiān)聽(tīng)來(lái)控制上拉

得到recycleview的布局管理器，通過(guò)布局管理器得到recycleview列表最后一條數(shù)據(jù)的位置，然后

判斷，加載數(shù)據(jù)

private intlastVisibleItemPosition;

//上拉加載

recyclerView.setOnScrollListener(newRecyclerView.OnScrollListener() {

@Override

public voidonScrollStateChanged(RecyclerView recyclerView, intnewState) {

super.onScrollStateChanged(recyclerView,newState);

RecyclerView.LayoutManager layoutManager = recyclerView.getLayoutManager();

lastVisibleItemPosition= ((LinearLayoutManager) layoutManager).findLastVisibleItemPosition();

if(newState ==RecyclerView.SCROLL_STATE_IDLE&&lastVisibleItemPosition+1==myAdapter_rv.getItemCount()) {

newHandler().postDelayed(newRunnable() {

@Override

public voidrun() {

page++;

presenterNew.getServerData(page);

}

},1000);

}

}

});
