android開發過程中，會遇到RecyclerView的做局部item刷新操作時候，出現了閃動問題.

解決方式一：

        mCountDownAdapter = new CountDownAdapter(this, mTimeDownBeanList);
        recycleView.setHasFixedSize(true);
        recycleView.setLayoutManager(new LinearLayoutManager(this));
        recycleView.addItemDecoration(new DividerItemDecoration(this,DividerItemDecoration.VERTICAL));
        ((SimpleItemAnimator) recycleView.getItemAnimator()).setSupportsChangeAnimations(false);
        recycleView.setAdapter(mCountDownAdapter);

recycleView.setHasFixedSize(true);
((SimpleItemAnimator) recycleView.getItemAnimator()).setSupportsChangeAnimations(false);

這兩個代碼需要添加

解決方式二：

同上述類似

        adapter = activity?.let { SteamChargeAdapter(it) }!!
        recycleView.setHasFixedSize(true)
        adapter.setHasStableIds(true)
        recycleView.layoutManager = gridLayoutManager
        (recycleView.itemAnimator as SimpleItemAnimator?)!!.supportsChangeAnimations = false

在RecyclerView適配器中重寫這個方法：

@Override
public long getItemId(int position) {
    return position;
}

以上兩種都可以解決，參照代碼修改就可以了
