2個活動之間的SharedElementTransition未正確動畫

Question

我一直在努力嘗試使我的sharedELementTransitions工作得很好而且流暢。但我有一個問題，我的ImageView跳轉，並不能正確縮放返回動畫。 Example我試圖儘可能多地複製預先存在的Android項目，甚至使用幾乎相同的代碼運行完美動畫的項目，而且似乎沒有任何解決方法。有沒有人有類似的問題？如果是這樣，你是如何解決它的？

檢查該解決方案是爲我工作（無論退出和返回的轉變正在）

MainActivity.java

public class MainActivity extends AppCompatActivity { 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
    setSupportActionBar(toolbar); 

    ListView listview = (ListView) findViewById(R.id.listView); 

    listview.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
     @Override 
     public void onItemClick(AdapterView<?> parent, View view, int position, long id) { 

      ImageView imageView = (ImageView) view.findViewById(R.id.imageListItem); 
      TextView textView = (TextView) view.findViewById(R.id.DummyText); 

      Intent intent = new Intent(MainActivity.this, SecondActivity.class); 

      Pair<View, String> p1 = Pair.create((View) textView, "newTrans"); 
      Pair<View, String> p2 = Pair.create((View) imageView, "profileAnimation"); 

      ActivityOptionsCompat optionsCompat = ActivityOptionsCompat.makeSceneTransitionAnimation(MainActivity.this, p1, p2); 
      startActivity(intent, optionsCompat.toBundle()); 

     } 
    }); 

    listview.setAdapter(new DummyAdapter()); 

} 

private class DummyAdapter extends BaseAdapter { 

    @Override 
    public int getCount() { 
     return 20; 
    } 

    @Override 
    public Object getItem(int position) { 
     return null; 
    } 

    @Override 
    public long getItemId(int position) { 
     return 0; 
    } 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 

     if (convertView == null) { 
      convertView = LayoutInflater.from(MainActivity.this).inflate(R.layout.list_item, parent, false); 
     } 
     return convertView; 

    } 
} 

}

使用你的風格里面的檔案：

<item name="android:windowContentTransitions">true</item>
