下面是swiperefreshlayout上拉刷新加载数据的步骤:
1. 在布局文件中添加swiperefreshlayout和recyclerview:
```
<android.support.v4.widget.SwipeRefreshLayout
android:id="@+id/swipe_refresh_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:id="@+id/recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</android.support.v4.widget.SwipeRefreshLayout>
```
2. 在代码中获取swiperefreshlayout和recyclerview的引用:
```
SwipeRefreshLayout swipeRefreshLayout = findViewById(R.id.swipe_refresh_layout);
RecyclerView recyclerView = findViewById(R.id.recycler_view);
```
3. 设置swiperefreshlayout的监听器,并在监听器中实现上拉刷新的逻辑:
```
swipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
@Override
public void onRefresh() {
//上拉刷新逻辑
//...
//刷新完成后调用setRefreshing(false)方法结束刷新
swipeRefreshLayout.setRefreshing(false);
}
});
```
4. 设置recyclerview的滑动监听器,并在监听器中实现下拉加载的逻辑:
```
recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
@Override
public void onScrollStateChanged(@NonNull RecyclerView recyclerView, int newState) {
super.onScrollStateChanged(recyclerView, newState);
if (!recyclerView.canScrollVertically(1) && newState == RecyclerView.SCROLL_STATE_IDLE) {
//下拉加载逻辑
//...
}
}
});
```
注意事项:
1. 在上拉刷新和下拉加载的逻辑中,需要注意数据的更新和添加。
2. 在下拉加载的逻辑中,需要在数据加载完成后通知recyclerview更新界面。
