切换到另一个活动时，Android recyclerview 动画看起来很跳跃

Question

所以我在让我的动画在 Android 的回收视图中正常工作时遇到问题。我正在列表的项目上设置一些动画，然后尝试开始一个新的活动，但回收视图会在进入下一个活动之前重新加载所有视图。我尝试过设置共享过渡，但它看起来仍然很跳跃。

public class ArticleListActivity extends ActionBarActivity implements
        LoaderManager.LoaderCallbacks<Cursor> {

    private int mFadeSleepTime = 16000;
    private int mWordBuffer = 200;//number of words we will display at a time
    private int mMaxChars = 0;
    private int mTotalPages = 0;
    private int mCurrentPage = 0;

    private Toolbar mToolbar;
    private SwipeRefreshLayout mSwipeRefreshLayout;
    private RecyclerView mRecyclerView;
    private ImageView mFAB;
    private int mTextPostion = 0;
    Animation fadeIn = new AlphaAnimation(0.0f, 1.0f);
    Animation fadeOut = new AlphaAnimation(1.0f, 0.0f);
    Animation mNewspaperClipSelectedAnimation;
    Animation mNewspaperClipSlideDownAnimation;
    Adapter mAdapter;
    String mbodyText;
    boolean mEndsInSpace = true;
    boolean mIsAnimating = false;

        final View toolbarContainerView = findViewById(R.id.toolbar_container);

            }

所以我终于想出了这个问题的答案，我在动画结束时将回收视图的子视图设置为不可见，并设置延迟动画过渡。这是工作代码。
