为什么Mac上的xterm中的emacs将ch解释为reverse-delete-char？(Why does emacs in an xterm on a Mac interpret c-h as backward-delete-char?)

 我终于能够解决它了。 对于那些感兴趣的人，这是如何： 
 
 为什么在开始转换之前删除半径？ 因为目标ImageView没有任何半径。 
 
 activity_detail.xml 
 
<ImageView
    android:id="@+id/iv_image_cover"
    android:layout_width="match_parent"
    android:layout_height="250dp"
    android:scaleType="centerCrop"
    android:src="@{animal.imageRes}"
    android:transitionName="animalImage"
    tools:src="@drawable/acat"
/>
 
 当我使用没有半径的CardView时，它并不显着，但它实际上变成了目标共享视图。 
 
 
 
 要实现半径到无半径转换，您必须将目标共享视图设置为四舍五入。 我只是使用卡片视图（半径）包裹它。 
 
 
 activity_detail.xml 
 
<android.support.v7.widget.CardView
    android:id="@+id/card"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:transitionName="card"
    app:cardCornerRadius="25dp"
>

    <ImageView
        android:id="@+id/iv_image_cover"
        android:layout_width="match_parent"
        android:layout_height="250dp"
        android:scaleType="centerCrop"
        android:src="@{animal.imageRes}"
        android:transitionName="animalImage"
        tools:src="@drawable/acat"
    />

</android.support.v7.widget.CardView>
 
 
 
 务必将makeSceneTransition更改为使用“card”而不是“animalImage” 
 
 
 ListActivity.class 
 
ActivityOptionsCompat option = ActivityOptionsCompat
.makeSceneTransitionAnimation(ListActivity.this, cardView, "card");

startActivity(intent, option.toBundle());
 
 
 
 在DetailActivity中，您可以在转换开始时启动半径动画。 
 
 
 DetailActivity.java 
 
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    getWindow().getSharedElementEnterTransition()
        .addListener(new Transition.TransitionListener() {
            @Override
            public void onTransitionStart(Transition transition) {
                ObjectAnimator animator = ObjectAnimator
                    .ofFloat(activityDetailBinding.card, "radius", 0);
                animator.setDuration(250);
                animator.start();
            }
        });
}
 
 
 
 享受平稳过渡 
 
 
  
 
 注意： 布局和活动的要点 

I finally able to solve it. For those who are interested, here's how:
 
Why it remove radius before starting transition? Because the target ImageView doesn't have any radius. 
 
activity_detail.xml
 
<ImageView
    android:id="@+id/iv_image_cover"
    android:layout_width="match_parent"
    android:layout_height="250dp"
    android:scaleType="centerCrop"
    android:src="@{animal.imageRes}"
    android:transitionName="animalImage"
    tools:src="@drawable/acat"
/>
 
When I use CardView without radius, it's not noticable, but it's actually turned into target Shared View.
 
 
 
To achieve radius to no-radius transition you have to set the target Shared View to be rounded. I'm simply wrap it using a Card View (with radius).
 
 
activity_detail.xml
 
<android.support.v7.widget.CardView
    android:id="@+id/card"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:transitionName="card"
    app:cardCornerRadius="25dp"
>

    <ImageView
        android:id="@+id/iv_image_cover"
        android:layout_width="match_parent"
        android:layout_height="250dp"
        android:scaleType="centerCrop"
        android:src="@{animal.imageRes}"
        android:transitionName="animalImage"
        tools:src="@drawable/acat"
    />

</android.support.v7.widget.CardView>
 
 
 
Be sure to change your makeSceneTransition to use "card" instead of "animalImage"
 
 
ListActivity.class
 
ActivityOptionsCompat option = ActivityOptionsCompat
.makeSceneTransitionAnimation(ListActivity.this, cardView, "card");

startActivity(intent, option.toBundle());
 
 
 
In the DetailActivity, you can start a radius animation when the transition start.
 
 
DetailActivity.java
 
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    getWindow().getSharedElementEnterTransition()
        .addListener(new Transition.TransitionListener() {
            @Override
            public void onTransitionStart(Transition transition) {
                ObjectAnimator animator = ObjectAnimator
                    .ofFloat(activityDetailBinding.card, "radius", 0);
                animator.setDuration(250);
                animator.start();
            }
        });
}
 
 
 
Enjoy the smooth transition
