Android材質設計 - 材質動作

Question

我想製作一個包含項目列表的應用程序。當用戶點擊一個項目時，我想用動畫效果爲其製作動畫效果here

是android庫包含它原生？如果沒有，這個動畫是否有一個3方圖書館？

你可以看到在這個視頻動畫： video link

您可以使用共享元素過渡

FirstFragment fragmentOne = ...; 
SecondFragment fragmentTwo = ...; 
// Check that the device is running lollipop 
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { 
    // Inflate transitions to apply 
    Transition changeTransform = TransitionInflater.from(this). 
      inflateTransition(R.transition.change_image_transform); 
    Transition explodeTransform = TransitionInflater.from(this). 
      inflateTransition(android.R.transition.explode); 

    // Setup exit transition on first fragment 
    fragmentOne.setSharedElementReturnTransition(changeTransform); 
    fragmentOne.setExitTransition(explodeTransform); 

    // Setup enter transition on second fragment 
    fragmentTwo.setSharedElementEnterTransition(changeTransform); 
    fragmentTwo.setEnterTransition(explodeTransform); 

    // Find the shared element (in Fragment A) 
    ImageView ivProfile = (ImageView) findViewById(R.id.ivProfile); 

    // Add second fragment by replacing first 
    FragmentTransaction ft = getFragmentManager().beginTransaction() 
      .replace(R.id.container, fragmentTwo) 
      .addToBackStack("transaction") 
      .addSharedElement(ivProfile, "profile"); 
    // Apply the transaction 
    ft.commit(); 
} 
else { 
    // Code to run on older devices 
}
