要实现这个效果，只需要再适配器getView之前，给每个条目的view设置相应的动画即可。
首先需要2个动画的xml文件。
在res下新建anim文件夹：（res/anim）
第一个动画xml文件：
up_from_bottom.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="@android:anim/decelerate_interpolator">
<translate
android:fromXDelta="0%" android:toXDelta="0%"
android:fromYDelta="100%" android:toYDelta="0%"
android:duration="400" />
</set>
down_from_top.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="@android:anim/decelerate_interpolator">
<translate
android:fromXDelta="0%" android:toXDelta="0%"
android:fromYDelta="-100%" android:toYDelta="0%"
android:duration="400" />
</set>
在listview的适配器中使用定义的动画：
代码如下：
private int lastPosition = -1;
@Override
public View getView(int position, View convertView, ViewGroup parent) {
//Load your view, populate it, etc...
View view = ...;
Animation animation = AnimationUtils.loadAnimation(getContext(), (position > lastPosition) ? R.anim.up_from_bottom : R.anim.down_from_top);
view.startAnimation(animation);
lastPosition = position;
return view;
}
