Android 共享元素在未设置动画的片段之间转换

所需的共享元素不会设置动画，它们只是显示/淡入，而不是从一个视图移动到另一个视图。可能有什么问题？我读过多篇教程，但都没有成功。这当然是一件小事。。。 我正在AVD6.0上测试

谢谢你的帮助

应用程序通过MainActivity加载起始片段启动

public void openFindDancerFragment() {
    FindDancerFragment findDancerFragment = new FindDancerFragment();
    getSupportFragmentManager()
            .beginTransaction()
            .replace(R.id.main_fragment_container, findDancerFragment)
            .addToBackStack(null)
            .commit();
}

这将带您进入开始片段

Start fragment.java 结束片段XML

舞者项目转换XML

您已经将transitionName添加到结束片段xml中，因此无需再次设置，删除代码即可。应该是这样的:

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container, 
 Bundle savedInstanceState) {
          Bundle bundle = getArguments();
          Bitmap imageBitmap = null;
          String dancerName = "";
          View view = inflater.inflate(R.layout.fragment_dancer_details, container, false);

          if (bundle != null) {
              imageBitmap = bundle.getParcelable("IMAGE");
              dancerName = bundle.getString("NAME_TEXT");
          }

          ((ImageView) view.findViewById(R.id.dancerImageDetails)).setImageBitmap(imageBitmap);
          ((TextView) view.findViewById(R.id.dancerNameDetails)).setText(dancerName);

          return view;
      }
