PullToRefreshListView在使用过程中会出现onRefreshing没有用

1、修改

@Override
	protected void onRefreshing(final boolean doScroll) {
		/**
		 * If we're not showing the Refreshing view, or the list is empty, the
		 * the header/footer views won't show so we use the normal method.
		 */
//		ListAdapter adapter = mRefreshableView.getAdapter();    //把这里注释掉就好
//		if (!mListViewExtrasEnabled || !getShowViewWhileRefreshing() || null == adapter || adapter.isEmpty()) {
//			super.onRefreshing(doScroll);
//			return;
//		}

		super.onRefreshing(false);

		final LoadingLayout origLoadingView, listViewLoadingView, oppositeListViewLoadingView;
		final int selection, scrollToY;

		switch (getCurrentMode()) {
			case MANUAL_REFRESH_ONLY:
			case PULL_FROM_END:
				origLoadingView = getFooterLayout();
				listViewLoadingView = mFooterLoadingView;
				oppositeListViewLoadingView = mHeaderLoadingView;
				selection = mRefreshableView.getCount() - 1;
				scrollToY = getScrollY() - getFooterSize();
				break;
			case PULL_FROM_START:
			default:
				origLoadingView = getHeaderLayout();
				listViewLoadingView = mHeaderLoadingView;
				oppositeListViewLoadingView = mFooterLoadingView;
				selection = 0;
				scrollToY = getScrollY() + getHeaderSize();
				break;
		}

		// Hide our original Loading View
		origLoadingView.reset();
		origLoadingView.hideAllViews();

		// Make sure the opposite end is hidden too
		oppositeListViewLoadingView.setVisibility(View.GONE);

		// Show the ListView Loading View and set it to refresh.
		listViewLoadingView.setVisibility(View.VISIBLE);
		listViewLoadingView.refreshing();

		if (doScroll) {
			// We need to disable the automatic visibility changes for now
			disableLoadingLayoutVisibilityChanges();

			// We scroll slightly so that the ListView's header/footer is at the
			// same Y position as our normal header/footer
			setHeaderScroll(scrollToY);

			// Make sure the ListView is scrolled to show the loading
			// header/footer
			mRefreshableView.setSelection(selection);

			// Smooth scroll as normal
			smoothScrollTo(0);
		}
	}
