调用notifyitemchanged时避免recyclerview显示滚动条

添加此行: android:scrollbars="none"

 <android.support.v7.widget.RecyclerView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:scrollbars="none"
    >
</android.support.v7.widget.RecyclerView>

对于临时隐身,请尝试以下操作:

recyclerView.setOverScrollMode(View.OVER_SCROLL_NEVER);
adapter.notifyItemChanged(row);
recyclerView.setOverScrollMode(View.OVER_SCROLL_ALWAYS);

在调用notifyitemchanged之前,请将滚动条大小设置为0,然后将其还原:

int size = recyclerView.getScrollBarSize();
recyclerView.setScrollBarSize(0);
adapter.notifyItemChanged(row);
recyclerView.setScrollBarSize(size);

这就是我如何达到我想要的要求。有 post 是解决问题的关键。

recyclerView.setVerticalScrollBarEnabled(false);
try {
    // Do something.
} finally {
    recyclerView.post(new Runnable() {
        @Override
        public void run() {
            // Not sure whether if check is necessary.
            if (recyclerView != null) {
                recyclerView.setVerticalScrollBarEnabled(true);
            }
        }
    });
}
