Use pulltorefresh to differentiate between pull-down refresh and pull-up loading

There are a lot of articles on how to use pulltorefresh. I will not go into details here.

When using the pulltorefresh library, you need to distinguish between pulltorefresh and pull-down. Baidu will get a method to modify the pulltorefresh. Java source file, such as callback.

In fact, pulltorefresh has provided us with a method to view the source code.

Com. handmark. pulltorefresh. Library. pulltorefreshbase. Java sets a piece of code to refresh the listener:

@Overridepublic final void setOnRefreshListener(OnRefreshListener<T> listener) {mOnRefreshListener = listener;mOnRefreshListener2 = null;}@Overridepublic final void setOnRefreshListener(OnRefreshListener2<T> listener) {mOnRefreshListener2 = listener;mOnRefreshListener = null;}

Let's look at com. handmark. pulltorefresh. Library. pulltorefreshbase. onrefreshlistener2 <t>

<span style="white-space:pre"></span>/** * An advanced version of the Listener to listen for callbacks to Refresh. * This listener is different as it allows you to differentiate between Pull * Ups, and Pull Downs. *  * @author Chris Banes */public static interface OnRefreshListener2<V extends View> {// TODO These methods need renaming to START/END rather than DOWN/UP/** * onPullDownToRefresh will be called only when the user has Pulled from * the start, and released. */public void onPullDownToRefresh(final PullToRefreshBase<V> refreshView);/** * onPullUpToRefresh will be called only when the user has Pulled from * the end, and released. */public void onPullUpToRefresh(final PullToRefreshBase<V> refreshView);}

Therefore, you can:

mPullRefreshListView.setOnRefreshListener(new  com.handmark.pulltorefresh.library.PullToRefreshBase.OnRefreshListener2<ListView>() {@Overridepublic void onPullDownToRefresh(PullToRefreshBase<ListView> refreshView) {Toast.makeText(PullToRefreshListActivity.this, "onPullDownToRefresh", Toast.LENGTH_SHORT).show();new GetDataTask().execute();}@Overridepublic void onPullUpToRefresh(PullToRefreshBase<ListView> refreshView) {Toast.makeText(PullToRefreshListActivity.this, "onPullUpToRefresh", Toast.LENGTH_SHORT).show();new GetDataTask().execute();}});

Use pulltorefresh to differentiate between pull-down refresh and pull-up loading
