Animation是Android给我们提供的一个可以实现动画效果的API,利用Animation我们可以实现一系列的动画效果,比如缩放动画,透明度动画,旋转动画,位移动画,布局动画,帧动画等等.Android基础动画分为四种,分别是Tween Animation,Frame Animation,Layout Animation,Property Animation.由于动画效果不好用图片进行展示,大家可以自己亲手试试看下效果.下面给出前三种简单的示例代码,帮助大家进行简单的动画入门.
(1) Tween Animation (变换动画)
Tween Animation按效果可以分为四种:Alpha,Scale,Translate,Rotate,它们有一下共同属性:
1. Duration: 动画持续时间(毫秒);
2. fillAfter: 设置为True,动画转换在动画结束后被应用;
3. fillBefore: 设置为True,动画转换在动画开始前被应用;
4. interpolator: 动画插入器(加速,减速插入器);
5. repeatCount: 动画重复次数;
6. repeatMode: 正序重复/倒序重复
7. startOffSet: 动画之间的时间间隔
① Alpha (渐变透明度动画)
MainActivity.java主要代码:
ImageView image = (ImageView) findViewById(id.image);
Animation loadAnimation = AnimationUtils.loadAnimation(this, R.anim.alpha);
image.startAnimation(loadAnimation);
alpha.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
<alpha
android:duration="1000"
android:fromAlpha="0.1"
android:toAlpha="1.0" >
</alpha>
</set>
② Scale (渐变尺寸缩放动画)
MainActivity.java主要代码:
ImageView image = (ImageView) findViewById(id.image);
Animation loadAnimation = AnimationUtils.loadAnimation(this, R.anim.scale);
image.startAnimation(loadAnimation);
scale.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
<scale
android:duration="2000"
android:fillAfter="false"
android:fromXScale="0.0"
android:fromYScale="0.0"
android:interpolator="@android:anim/accelerate_decelerate_interpolator"
android:pivotX="50%"
android:pivotY="50%"
android:toXScale="1.0"
android:toYScale="1.0" />
</set>
③ Translate (位置移动动画)
MainActivity.java主要代码:
ImageView image = (ImageView) findViewById(id.image);
Animation loadAnimationloadAnimation = AnimationUtils.loadAnimation(this, R.anim.translate);
image.startAnimation(loadAnimation);
translate.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
<translate
android:duration="1000"
android:fromXDelta="10"
android:fromYDelta="10"
android:toXDelta="100"
android:toYDelta="100" />
</set>
④ Rotate (旋转动画)
MainActivity.java主要代码:
ImageView image = (ImageView) findViewById(id.image);
Animation loadAnimation loadAnimation = AnimationUtils.loadAnimation(this, R.anim.rotate);
image.startAnimation(loadAnimation);
rotate.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
<rotate
android:duration="1000"
android:fromDegrees="0"
android:interpolator="@android:anim/accelerate_decelerate_interpolator"
android:pivotX="50%"
android:pivotY="50%"
android:toDegrees="+360" />
</set>
(2) Layout Animation (布局动画)
MainActivity.java主要代码:
Intent intent=new Intent(MainActivity.this,ListActivity.class);
startActivity(intent);
ListActivity.java代码:
package com.example.caobotao.learnanimation;
import java.util.ArrayList;
import java.util.List;
import android.app.Activity;
import android.os.Bundle;
import android.view.animation.AnimationUtils;
import android.view.animation.LayoutAnimationController;
import android.widget.ArrayAdapter;
import android.widget.ListView;
public class ListActivity extends Activity{
private ListView listView;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.list_layout);
listView=(ListView) findViewById(R.id.listView);
List<String>list=new ArrayList<String>();
for(int i=0;i<20;i++)
{
list.add("示例"+i);
}
ArrayAdapter<String>adapter=new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, list);
listView.setAdapter(adapter);
LayoutAnimationController lac=new LayoutAnimationController(AnimationUtils.loadAnimation(this, R.anim.zoom_in));
lac.setOrder(LayoutAnimationController.ORDER_NORMAL);
listView.setLayoutAnimation(lac);
listView.startLayoutAnimation();
}
}
zoom_in.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/decelerate_interpolator" >
<scale
android:duration="1000"
android:fromXScale="0.1"
android:fromYScale="0.1"
android:pivotX="50%"
android:pivotY="50%"
android:toXScale="1.0"
android:toYScale="1.0" />
<alpha
android:duration="1000"
android:fromAlpha="0"
android:toAlpha="1.0" />
</set>
(3) Frame Animation (帧动画)
MainActivity.java主要代码:
ImageView image = (ImageView) findViewById(id.image);
image.setImageResource(R.drawable.anim_list);
AnimationDrawable animationDrawable = (AnimationDrawable) image.getDrawable();
animationDrawable.start();
anim_list.xml
<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:drawable="@mipmap/one"
android:duration="500"/>
<item
android:drawable="@mipmap/two"
android:duration="500"/>
<item
android:drawable="@mipmap/three"
android:duration="500"/>
<item
android:drawable="@mipmap/four"
android:duration="500"/>
<item
android:drawable="@mipmap/five"
android:duration="500"/>
<item
android:drawable="@mipmap/six"
android:duration="500"/>
</animation-list>
