如何在实现swipeRefreshLayout时防止用户滚动？
如何在实现swipeRefreshLayout时防止用户滚动？
提问于 2019-05-29 05:00:08
在我的应用程序中，我有一个包含20 - 30个项目的回收器视图，我有拉动来刷新内容的功能，我想防止用户在刷新过程中滚动视图，因为如果用户绑定到滚动，并且正在进行regresh，就会产生错误，但我真的不知道该怎么做:/
eRecyclerView = findViewById(R.id.recycler_view);
RecyclerView.LayoutManager eLayoutManager = new GridLayoutManager(this, 2);
eRecyclerView.setLayoutManager(eLayoutManager);
swipeRefreshLayout = findViewById(R.id.refreshSecondLevel);
swipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
@Override
public void onRefresh() {
loadNewContent();
Handler delay = new Handler();
delay.postDelayed(new Runnable() {
@Override
public void run() {
swipeRefreshLayout.setRefreshing(false);
}
}, 3000);
}

您应该在RecyclerView.LayoutManager上重写canScrollVertically方法
public class ToggledScrollLayoutManager extends LinearLayoutManager {
private boolean mIsScrollEnabled = true;
public ToggledScrollLayoutManager(Context context) {
super(context);
}
public void setScrollEnabled(boolean enabled) {
this.mIsScrollEnabled = enabled;
}
@Override
public boolean canScrollVertically() {
return mIsScrollEnabled && super.canScrollVertically();
}
}然后在用户刷新页面时使用它：
recyclerView = findViewById(R.id.recyclerView);
ToggledScrollLayoutManager layoutManager = new ToggledScrollLayoutManager();
recyclerView.setLayoutManager(layoutManager);
swipeRefreshLayout = findViewById(R.id.refreshSecondLevel);
swipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
@Override
public void onRefresh() {
loadNewContent();
layoutManager.setScrollEnabled(false);
Handler delay = new Handler();
delay.postDelayed(new Runnable() {
@Override
public void run() {
swipeRefreshLayout.setRefreshing(false);
layoutManager.setScrollEnabled(true);
}
}, 3000);
}
}
