I have a listview with custom listadapter, which populates the listview with a checkbox and some textviews. When the user selects a checkbox, I need a button bar to slide into the view from the bottom of the screen and sit there. I have made the buttons-bar and can make it appear and disappear from screen by changing it's visibility to "gone" and "visible", but it does not do these with slide-in and slide-out effect. How do I make it do those animations??

推荐答案

您想使用动画XML资源的。

下面是一个动画XML的一个例子，将幻灯片的对象从屏幕到永远取而代之的是你的布局中底：

Here is an example of an Animation xml that will 'slide' the object up from the bottom of the screen to where ever its place is within your layout:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate android:fromYDelta="100%p" android:toYDelta="0%p" android:duration="300"/>
</set>

您把在你的RES /阿尼姆的文件夹，然后使用这个Java code到动画的看法：

You will put that in your res/anim folder then use this java code to animate your view:

slideUpIn = AnimationUtils.loadAnimation(this, R.anim.slide_up_in);
yourButtonBarView.startAnimation(slideUpIn);

您会希望把你在哪里得到你的复选框被选中回调内部的startAnimation电话。

You'll want to put the startAnimation call inside where you get the callback that your CheckBox has been checked.
