IllegalStateException: Cannot call this method while RecyclerView is computing a layout or scrolling

当正在滑动过程中调用notifyDataSetChanged刷新数据就会出现这个异常：

java.lang.IllegalStateException: Cannot call this method while RecyclerView is computing a layout or scrolling android.support.v7.widget.RecyclerView{d510381 VFED..... .F...... 0,0-1080,1731 #7f08007d app:id/rv_1s}, adapter:com.wang.daojishi.Example1sActivity$1@155fc26, layout:android.support.v7.widget.GridLayoutManager@fd42067, context:com.wang.daojishi.Example1sActivity@dca765c
at android.support.v7.widget.RecyclerView.assertNotInLayoutOrScroll(RecyclerView.java:2769)
at android.support.v7.widget.RecyclerView$RecyclerViewDataObserver.onChanged(RecyclerView.java:5177)

原因：RecyclerView不允许计算布局过程中调用刷新方法。

解决方法1：递归等到可以修改后再修改：

/**
     * 递归等待滑动停止后再删除数据
     *
     * @param deleteData 不建议使用position，因为如果出现多个等待position将会出错
     */
    public void waitDelete(final XXData deleteData) {
        if (mRv.isComputingLayout()) {
            mRv.postDelayed(new Runnable() {
                @Override
                public void run() {
                    waitDelete(deleteData);
                }
            }, 100);
        } else {
            mAdapter.getList().remove(deleteData);
            mAdapter.notifyDataSetChanged();
        }
    }

解决方法2：强制停止滑动（有点突兀），然后刷新数据：

/**
     * 强制停止滑动，然后刷新数据
     *
     * @param deleteData 不建议使用position，因为如果出现多个等待position将会出错
     */
    public void waitDelete(final Long deleteData) {
        //强制停止
        mRv.dispatchTouchEvent(MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_CANCEL, 0, 0, 0));
        mRv.postDelayed(new Runnable() {
            @Override
            public void run() {
                mAdapter.getList().remove(deleteData);
                mAdapter.notifyDataSetChanged();
            }
        }, 100);
    }
