问题描述

我有一个线性布局两种观点，我以编程方式改变自己的layout_weight财产。有没有一种方法，我可以在动画重量这种变化，所以当重量迈向一个新的大小改变看法幻灯片？

I have two views in a linear layout, I programmatically change their layout_weight property. Is there a way I could animate this change in weight so when the weight is changed views slides towards a new size?

推荐答案

我一直在寻找这一点。最后，我通过动画的父母，如果你有一个的LinearLayout两个视图其中工程非常漂亮的weightsum财产解决它。

I have been looking at this as well. Eventually I solved it by animating the weightsum property of the parent, which works very nice if you have two views in a LinearLayout.

在下面的例子中，如果动画weightSum从1.0到2.0，屏幕2将很好地动画进入视野。

In the example below, if you animate the weightSum from 1.0 to 2.0, Screen 2 will animate nicely into view.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/dual_pane"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="horizontal"
    android:weightSum="1.0">

<!-- Screen 1 -->
<LinearLayout
    android:layout_width="0dp"
    android:layout_height="match_parent"
    android:background="#ff0000"
    android:layout_weight="1">
</LinearLayout>

<!-- Screen 2 -->
<LinearLayout
    android:layout_width="0dp"
    android:layout_height="match_parent"
    android:background="#ff6600"
    android:layout_weight="1">
</LinearLayout>
</LinearLayout>
