使用swipelayout进行动画冻结

标签: java android animation swipe

添加2个新功能(swipelayout + animation)后,我的ui会冻结。

我有一个包含电影对象的recyclerview。如果我添加/删除/修改电影,我会调用我的电影管理员,因为它有一个通知概念(所有想要使用数据的视图都必须在此管理器上注册)。 在添加新功能之前,一切正常。

我使用此swipelayout: https://github.com/daimajia/AndroidSwipeLayout

目前这些项目如下:

刷完后:

如果我有4个项目,冻结总是可以重现的。我在第二个项目上滑动并删除它。然后它会像我想要的那样消失。 在我刷了" new"第二项是冻结10-15秒。

项目的布局xml:

适配器的相关代码:

  @Override
  public void onBindViewHolder(final CDMMoviesAdapter.IC_ViewHolder p_Holder, final int p_iPosition) {

    // more unimportant code...

    p_Holder.m_SwipeLayout.setShowMode(SwipeLayout.ShowMode.PullOut);

    // Drag From Right
    p_Holder.m_SwipeLayout.addDrag(SwipeLayout.DragEdge.Right, p_Holder.m_SwipeLayout.findViewById(R.id.item_movie_swipe_bottom_wrapper));

    // Handling different events when swiping
    p_Holder.m_SwipeLayout.addSwipeListener(new SwipeLayout.SwipeListener() {
      @Override
      public void onClose(SwipeLayout layout) {
        //when the SurfaceView totally cover the BottomView.
      }

      @Override
      public void onUpdate(SwipeLayout layout, int leftOffset, int topOffset) {
        //you are swiping.
      }

      @Override
      public void onStartOpen(SwipeLayout layout) {

      }

      @Override
      public void onOpen(SwipeLayout layout) {
        //when the BottomView totally show.
      }

      @Override
      public void onStartClose(SwipeLayout layout) {

      }

      @Override
      public void onHandRelease(SwipeLayout layout, float xvel, float yvel) {
        //when user's hand released.
      }
    });

    p_Holder.m_SwipeLayout.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View p_View) {
        if((((SwipeLayout) p_View).getOpenStatus() == SwipeLayout.Status.Close)) {
          Intent l_Intent = new Intent();
          Bundle l_Bundle = new Bundle();
          l_Bundle.putLong(CDMMovieDetailsActivity.ARG_MOVIE, l_MovieID);
          l_Intent.putExtras(l_Bundle);
          l_Intent.setClass(l_Context, CDMMovieDetailsActivity.class);
          l_Context.startActivity(l_Intent);
        }
      }
    });

    p_Holder.m_tvDelete.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View p_View) {
        Animation l_DeleteAnimation = AnimationUtils.loadAnimation(l_Context, R.anim.slide_out);
        l_DeleteAnimation.setAnimationListener(new Animation.AnimationListener() {
          @Override
          public void onAnimationStart(Animation animation) {
          }

          @Override
          public void onAnimationRepeat(Animation animation) {
          }

          @Override
          public void onAnimationEnd(Animation animation) {
            mItemManger.removeShownLayouts(p_Holder.m_SwipeLayout);
            CDMMovieManager.getInstance().removeMovieID(m_List, m_MovieIDs.get(p_iPosition));
            mItemManger.closeAllItems();
          }
        });

        p_Holder.m_View.startAnimation(l_DeleteAnimation);
      }
    });

    // mItemManger is member in RecyclerSwipeAdapter Class
    mItemManger.bindView(p_Holder.itemView, p_iPosition);

    // more unimportant code...
  }

  /**
   * This class is the viewholder. For internal use only.
   */
  public static class IC_ViewHolder extends RecyclerView.ViewHolder {

    /**
     * Constructor
     *
     * @param p_View the view
     */
    public IC_ViewHolder(View p_View) {
      super(p_View);

      m_View = p_View;
      m_SwipeLayout = (SwipeLayout) p_View.findViewById(R.id.item_movie_swipe_layout);

      m_tvNameYear = (TextView) p_View.findViewById(R.id.item_movie_list_name_year);
      m_ivPoster = (ImageView) p_View.findViewById(R.id.item_movie_list_poster);
      m_tvGenre = (TextView) p_View.findViewById(R.id.item_movie_list_genre);
      m_tvViewed = (TextView) p_View.findViewById(R.id.item_movie_list_viewed);

      m_tvDelete = (TextView) p_View.findViewById(R.id.item_movie_bottom_delete_desc);
    }

    public View m_View;
    public SwipeLayout m_SwipeLayout;

    public TextView m_tvNameYear;
    public ImageView m_ivPoster;
    public TextView m_tvGenre;
    public TextView m_tvViewed;

    public TextView m_tvDelete;
  }

CDMMovieManager.getInstance().removeMovieID(m_List, m_MovieIDs.get(p_iPosition));中,电影将被删除,所有注册的视图都会收到通知。在这种情况下,此适配器的片段将调用m_Adapter.notifyDataSetChanged();

动画文件:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
        android:duration="250"
        android:fromXDelta="0%"
        android:toXDelta="-100%"/>
</set>

我尝试了View.clearAnimation()Animation.setAnimationListener(null)之类的内容,但我总是遇到这个问题。 Plase询问您是否需要更多信息。

更新

如果我尝试滑动下一个项目,则只会出现问题。 (例如,删除第2项。之后尝试刷第3项,这是新的第二项 - &gt;冻结我尝试滑动的项目)。只有在刷上任何其他项目时才能删除冻结。

答案 0 :(得分:0)

我解决了我的问题。这个答案对我有帮助:How to animate RecyclerView items when they appear

我将此代码添加到我的适配器:

@Override
public void onViewDetachedFromWindow(IC_ViewHolder p_Holder) {
  p_Holder.m_View.clearAnimation();
}
