T为你要实现下拉刷新的View的类型，如ListView.       

 /*
     * 初始化mContentView
     * @see com.uit.pullrefresh.base.PullRefreshBase#initContentView()
     */
    @Override
    protected void initContentView() {
        // 初始化mContentView
        mContentView = new ListView(getContext());
        // 设置OnScrollListener, 用以实现滑动到底部时的自动加载功能，如果不需要该功能可以不设置.
        mContentView.setOnScrollListener(this);
    }

    /*
     * 是否滑动到了顶端，如果返回true, 则表示到了顶端，用户继续下拉则触发下拉刷新
     * @see com.uit.pullrefresh.base.PullRefreshBase#isTop()
     */
    @Override
    protected boolean isTop() {
        View firstChild = mContentView.getChildAt(0);
        if (firstChild == null) {
            return true;
        }
        return mContentView.getFirstVisiblePosition() == 0
                && (firstChild.getTop() >= mContentView.getTop());
    }

    /*
     * 下拉到listview 最后一项时则返回true, 将出发自动加载
     * @see com.uit.pullrefresh.base.PullRefreshBase#isShowFooterView()
     */
    @Override
    protected boolean isShowFooterView() {
        if (mContentView == null || mContentView.getAdapter() == null) {
            return false;
        }

        return mContentView.getLastVisiblePosition() == mContentView.getAdapter().getCount() - 1;
    }
