最新的recyclerview加了autoMeasure功能,在 RecyclerAdapterWithHF 中的onCreateViewHolder里面, 自己创建的HeaderFooterView不应该在用MATCH_PARENT了.

FrameLayout frameLayout = new FrameLayout(viewGroup.getContext()); // make sure it fills the space frameLayout.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT)); return new HeaderFooterViewHolder(frameLayout);

我在运行Demo的时候发现2个问题:都是上拉加载更多 第一个： 若是ListView，那么当footView出现一点点的时候就会加载更多，而RecyclerView需要footView全部出现才会加载更多。 第二个： mData.add(new String(" RecyclerView item - add " + page)); mAdapter.notifyDataSetChanged(); 必须在一起，如果采用mHandler.sendEmptyMessageDelayed(123, 1500);把加载数据和 mAdapter.notifyDataSetChanged();分开，会有bug。

    ptrClassicFrameLayout.setPtrHandler(new PtrDefaultHandler() {

        @Override
        public void onRefreshBegin(PtrFrameLayout frame) {
                 mData.add(new String("  RecyclerView item  - add " + page));
                mHandler.sendEmptyMessageDelayed(123, 1500);
        }
    });


private Handler mHandler = new Handler() {
    @Override
    public void handleMessage(Message msg) {
        super.handleMessage(msg);
        if (msg.what == 123) {
            mAdapter.notifyDataSetChanged();
            ptrClassicFrameLayout.loadMoreComplete(true);
            page++;
            Toast.makeText(RecyclerViewActivity.this, "load more complete", Toast.LENGTH_SHORT).show();
        }
    }
};

会出现bug:一次正常有1.5s的间隔，一次没有（直接是加载更多后的结果），依次循环。

@Chanven 请问下想弄成类似qq那样可以多点连续下拉的问题 我参考其他库的做法在PtrFrameLayout里面添加了下面代码

 @Override
    public boolean dispatchTouchEvent(MotionEvent e) {
        if (!isEnabled() || mContent == null || mHeaderView == null) {
            return dispatchTouchEventSupper(e);
        }
        dealMulTouchEvent(e);
        int action = e.getAction();
        switch (action) {
            case MotionEvent.ACTION_UP:
            case MotionEvent.ACTION_CANCEL:
                mPtrIndicator.onRelease();
                if (mPtrIndicator.hasLeftStartPosition()) {
                    if (DEBUG) {
                        PtrCLog.d(LOG_TAG, "call onRelease when user release");
                    }
                    onRelease(false);
                    if (mPtrIndicator.hasMovedAfterPressedDown()) {
                        sendCancelEvent();
                        return true;
                    }
                    return dispatchTouchEventSupper(e);

但是当2个在屏幕上面,一个手指滑动然后抬起,会出现位置忽然抖动的情况，请问下这个应该怎么解决呢？

GitHub changed the way Markdown headings are parsed, so this change fixes it.

在activity的viewpager中使用fragment，fragment中使用了您的CommonPullToRefresh，报 java.lang.NullPointerException: Attempt to invoke virtual method 'void com.chanven.lib.cptr.PtrClassicFrameLayout.disableWhenHorizontalMove(boolean)' on a null object reference 的错误

使用以下依赖： compile 'com.android.support:appcompat-v7:25.0.0' compile 'com.android.support:recyclerview-v7:25.0.0' compile 'com.android.support:cardview-v7:25.0.0' 进行上拉加载操作，需要将footerview上拉到顶部才开始回调加载方法。
