问题描述

我一直在试图找出如何构建一个动画制作器 (xml)，它会产生向上和向下滑动的效果.这将如何运作?谢谢

I've been trying to find out how to build an animator (xml) that will cause a slide up and slide down effect. How would that work? Thanks

推荐答案

在项目的 res 文件夹中创建一个文件夹 anim.现在为 slide_up 动画添加 slide_up.xml.然后为下滑动画添加slide_down.xml.

Make a folder anim in the res folder of the project. Now add slide_up.xml for slide_up animation. Then add slide_down.xml for slide down animation.

slide_down.xml 的代码:

Code for slide_down.xml:

<set xmlns:android="http://schemas.android.com/apk/res/android">  
    <translate android:fromXDelta="0" android:toYDelta="-1000" android:duration="1500"/>
</set>

slide_up.xml 的代码:

Code for slide_up.xml:

<set xmlns:android="http://schemas.android.com/apk/res/android">  
    <translate android:fromXDelta="0" android:toYDelta="1000" android:duration="1500"/>
</set>

然后在 onCreate 方法中加载动画:

Then load the animation in onCreate method consequently:

Animation slideUp = AnimationUtils.loadAnimation(getApplicationContext(), R.anim.slide_up);

要开始将它附加到您想要设置动画的对象:

To start it attach it to object you want to be animated:

ImageView img = (ImageView) findViewById(R.id.img);
img.startAnimation(slideUp);
