Android转换不关心transitionSet中的targetId

Question

我对如何使用transitionSet感到困惑.这是我的定义:

<?xml version="1.0" encoding="utf-8"?>
<transitionSet xmlns:android="http://schemas.android.com/apk/res/android" android:transitionOrdering="sequential">
    <slide android:slideEdge="bottom" android:startDelay="0">
        <targets>
            <target android:targetId="@id/action_save" />
        </targets>
    </slide>
    <slide android:slideEdge="top">
        <targets>
            <target android:targetId="@id/image_album_background" />
        </targets>
    </slide>
    <slide
        android:duration="500"
        android:slideEdge="bottom">
        <targets>
            <target android:targetId="@id/fields_container" />
        </targets>
    </slide>
</transitionSet>

这样,所有视图都将从底部边缘滑动.但是,如果我将订单更改为:

<?xml version="1.0" encoding="utf-8"?>
<transitionSet xmlns:android="http://schemas.android.com/apk/res/android" android:transitionOrdering="sequential">
    <slide android:slideEdge="top">
        <targets>
            <target android:targetId="@id/image_album_background" />
        </targets>
    </slide>
    <slide android:slideEdge="bottom" android:startDelay="0">
        <targets>
            <target android:targetId="@id/action_save" />
        </targets>
    </slide>
    <slide
        android:duration="500"
        android:slideEdge="bottom">
        <targets>
            <target android:targetId="@id/fields_container" />
        </targets>
    </slide>
</transitionSet>

然后,所有都将从顶部边缘滑动.

似乎Android只关心第一次转换.

更新:这是布局:

        <com.melnykov.fab.FloatingActionButton

            android:layout_height="wrap_content"

            android:layout_margin="16dp"
            android:src="@drawable/ic_action_save"
            fab:fab_colorNormal="@color/accent_shade"
            fab:fab_colorRipple="#66FF9800" />

    </FrameLayout>

这是如何打开布局:

String transitionName = "transition_album_cover";
if (AnimationViews.albumCover != null) {
    fragmentTx.addSharedElement(AnimationViews.albumCover, transitionName);
}

TransitionInflater inflater = TransitionInflater.from(this);
editorFragment.setEnterTransition(inflater.inflateTransition(R.transition.editor_fragment_enter));

Answer 1

我刚刚尝试过这个，它对我来说效果很好，所以我必须认为它与你的具体目标有关。我的猜测是 image_album_background 包含 action_save 和 fields_container。如果是这样，这两个视图仍然会在它们的容器内滑动。

解决这个问题的简单方法是将 image_album_background 移动到其他两个的同级而不是父级中。如果您还没有能够执行此操作的容器（例如 LinearLayout），则可以使用一个额外的级别来完成此操作：

<FrameLayout ...>
    <ImageView android:id="@+id/image_album_background"/>
    <other views.../>
</FrameLayout>
