我想在我的應用程序中實現共享轉換。我想要RecyclerView中的ImageView將出現在下一個片段中,以便從RecyclerView共享轉換爲片段。但它不起作用。這是我做到的。共享轉換不工作recyclerview到片段
回收站的項目佈局

片段佈局
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ImageView
android:id="@+id/iv_cover"
android:transitionName="cover"
android:layout_width="match_parent"
android:layout_height="200dp"
android:scaleType="centerCrop" />
<TextView
android:id="@+id/tv_title"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<TextView
android:id="@+id/tv_description"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<Button
android:id="@+id/btn_story"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Read Full Story"
android:layout_gravity="center"/>
</LinearLayout>
下面是我用
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
//ImageView ivCover = (ImageView) getActivity().findViewById(R.id.iv_cover);
getActivity().getSupportFragmentManager()
.beginTransaction()
.replace(android.R.id.content, feedFragment, "Feed")
.addSharedElement(cover, "cover")
.addToBackStack("Feed")
.commit();
}
這裏的java代碼是Fragment
代碼
@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
postponeEnterTransition();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
setSharedElementEnterTransition(TransitionInflater.from(getContext()).inflateTransition(android.R.transition.move));
}
}
private void loadData() {
String title = null;
String description = null;
String urlToImage = null;
String url = null;
try {
title = getArguments().getString(ARG_PARAM1);
description = getArguments().getString(ARG_PARAM2);
url = getArguments().getString(ARG_PARAM3);
urlToImage = getArguments().getString(ARG_PARAM4);
} catch (Exception e) {
e.printStackTrace();
}
if (title != null)
tvTitle.setText(title);
if (tvDescription != null)
tvDescription.setText(description);
if (urlToImage != null)
Picasso.with(getActivity()).load(urlToImage).into(ivCover, new Callback() {
@Override
public void onSuccess() {
startPostponedEnterTransition();
}
@Override
public void onError() {
startPostponedEnterTransition();
}
});
}
這裏是風格
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
<item name="android:windowContentTransitions">true</item>
</style>
我到底做錯了什麼?請在這裏指導我。由於
它以某種方式工作,但當我按回按鈕。它不像我打開片段時那樣動畫。我的意思是在後面沒有動畫,但我想保留在開始時發生的事情。 –
回收動畫在recyclerview-v7:25.1.1中無法正常工作。所以請耐心等待,直到Google解決。雖然你仍然可以嘗試添加一行setSharedElementReturnTransition ... –
如果它是值得的,請接受答案,併爲此榮幸。 –
