我和你遇到了同样的问题。购买我找到了解决方案。你知道，这个问题有很多原因。我只是展示我的方式。希望能帮到你。
有两个片段。一个有一个 RecyclerView 小部件：
ListFragment.java
public class ListFragment extends Fragment implements RecyclerItemInter {
@Bind(R.id.recycler_view)
RecyclerView recyclerView;
private OnListItemClickListener onListItemClickListener;
public void setOnListItemClickListener(ListFragment.OnListItemClickListener onListItemClickListener) {
this.onListItemClickListener = onListItemClickListener;
}
public ListFragment() {
}
public static ListFragment newInstance() {
ListFragment fragment = new ListFragment();
return fragment;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_list, container, false);
ButterKnife.bind(this, view);
recyclerView.setLayoutManager(new GridLayoutManager(getActivity(), 2));
RecyclerAdapter2 adapter = new RecyclerAdapter2(BEAUTY_BEANS);
recyclerView.setAdapter(adapter);
adapter.setItemInter(this);
return view;
}
private static final BeautyBean[] BEAUTY_BEANS = {
new BeautyBean("Avril Lavigne1", "Avril was born in Canada, the Canadian singer, songwriter creators, actors."),
new BeautyBean("Avril Lavigne2", "Avril was born in Canada, the Canadian singer, songwriter creators, actors."),
new BeautyBean("Avril Lavigne3", "Avril was born in Canada, the Canadian singer, songwriter creators, actors."),
new BeautyBean("Avril Lavigne4", "Avril was born in Canada, the Canadian singer, songwriter creators, actors."),
new BeautyBean("Avril Lavigne5", "Avril was born in Canada, the Canadian singer, songwriter creators, actors.")
};
@Override
public void onDestroyView() {
super.onDestroyView();
ButterKnife.unbind(this);
}
@Override
public void onItemClick(View view, int position) {
}
@Override
public void onIvClick(RecyclerAdapter2.ViewHolder holder, int position) {
OtherFragment otherFragment = OtherFragment.newInstance();
otherFragment.setSharedElementEnterTransition(new CustomTransition());
otherFragment.setSharedElementReturnTransition(new CustomTransition());
/*if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
otherFragment.setEnterTransition(new Fade());
setExitTransition(new Fade());
}*/
getActivity().getSupportFragmentManager()
.beginTransaction()
.replace(R.id.frame_layout, otherFragment)
.addToBackStack(null)
.addSharedElement(holder.getPicIv(), getString(R.string.transition_img))
.commit();
}
那么你应该将 TransitionName 设置为 RecyclerView 中的每个 ImageView：
@Override
public void onBindViewHolder(final ViewHolder holder, final int position) {
if (items[position].getImageId() != 0) {
holder.getPicIv().setImageResource(items[position].getImageId());
}
ViewCompat.setTransitionName(holder.getPicIv(), String.valueOf(position) + "_beauty");
holder.getTitleTv().setText(items[position].getName());
holder.getDescTv().setText(items[position].getDesc());
holder.getLinearLayout().setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (null != itemInter) {
itemInter.onItemClick(holder.itemView, position);
}
}
});
holder.getPicIv().setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (null != itemInter) {
itemInter.onIvClick(holder, position);
}
}
});
}
点击列表跳转到OtherFragment。
其他片段.java
public class OtherFragment extends Fragment {
public OtherFragment() {
}
public static OtherFragment newInstance() {
OtherFragment fragment = new OtherFragment();
return fragment;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_other, container, false);
}
}
片段其他.xml
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.jacksen.supportlibrarydemo.fragment.OtherFragment">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/bg_detail_header"
android:transitionName="@string/transition_img" />
<android.support.design.widget.FloatingActionButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="end|bottom"
android:layout_margin="@dimen/fab_margin"
android:src="@drawable/ic_backup_white_36dp"
android:transitionName="@string/transition_fab"
app:borderWidth="0dp"
app:elevation="5dp"
app:pressedTranslationZ="10dp"
app:rippleColor="@color/color_gray" />
问题的症结在于这个xml。一开始，我设置了属性“transitionName”及其父布局。
实际上我们不需要在父Layout上添加属性。
只需将transitionName添加到您要转换的内容即可。
好的，这就是我的解决方案。
