————————————案例结构很复杂一步步来————————————
1、activity_main.xml(首先看启动界面布局文件,里面有2个button)
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:onClick="toTestVA"
android:text="Test View Animation" />
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:onClick="toTestDA"
android:text="Test Drawable Animation" />
</LinearLayout>package com.atguigu.l10_animation;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
/*
* 测试View Annimation
*/
public void toTestVA(View v) {
startActivity(new Intent(this, VAActivity.class));
}
/*
* 测试Drawable Annimation
*/
public void toTestDA(View v) {
startActivity(new Intent(this, DAActivity.class));
}
}
3、首先看startActivity(new Intent(this, VAActivity.class));启动的界面布局文件如下
activity_animation_va.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<Button
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:onClick="startCodeScale"
android:text="Code Scale" />
<Button
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:onClick="startXmlScale"
android:text="Xml Scale" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<Button
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:onClick="startCodeRotate"
android:text="Code Rotate" />
<Button
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:onClick="startXmlRotate"
android:text="Xml Rotate" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<Button
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:onClick="startCodeAlpha"
android:text="Code Alpha" />
<Button
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:onClick="startXmlAlpha"
android:text="Xml Alpha" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<Button
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:onClick="startCodeTranslate"
android:text="Code Translation" />
<Button
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:onClick="startXmlTranslate"
android:text="Xml Translation" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<Button
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:onClick="startCodeAnimationSet"
android:text="Code AnimationSet"
android:textSize="15sp"/>
<Button
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:onClick="startXmlAnimationSet"
android:text="Xml AnimationSet"
android:textSize="15sp"/>
</LinearLayout>
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:onClick="testAnimationListener"
android:text="Test Animation Listener"/>
<ImageView
android:id="@+id/iv_animation"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/atguigu"
android:layout_gravity="center_horizontal"/>
<TextView
android:id="@+id/tv_animation_msg"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="显示动画描述信息"
android:textSize="18dp"/>
</LinearLayout>4、然后看VAActivity.java(就是操作activity_animation_va.xml视图的代码)
VAActivity.java(代码里有5种简单的动画效果,每种动画效果都有代码和.xml文件2种形式)
package com.atguigu.l10_animation;

}5、针对上面的代码,下面是依次的动画的布局文件
5-1、缩放动画布局文件如下
scale_test.xml
<?xml version="1.0" encoding="utf-8"?>
<scale xmlns:android="http://schemas.android.com/apk/res/android"
android:fromXScale="0.0"
android:toXScale="1.5"

android:toYScale="1.0"
android:startOffset="1000"
android:duration="3000"
android:pivotX="100%"
android:pivotY="100%"
android:fillAfter="true"/>
<!--
Animation.ABSOLUTE :
数值(默认以px为单位)
Animation.RELATIVE_TO_SELF :
百分数,如:50% (以当前视图的宽度或高度其为基数来计算)
Animation.RELATIVE_TO_PARENT :
百分数+p,如:50%p (以父视图的宽度或高度其为基数来计算)
-->rotate_test.xml
<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:fromDegrees="90"
android:toDegrees="-90"
android:duration="5000">
</rotate>
<!--
Xml旋转动画: 以左顶点为坐标, 从正90度到负90度, 持续5s
默认中心点左顶点开始
-->alpha_test.xml
<?xml version="1.0" encoding="utf-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
android:fromAlpha="1.0"

android:duration="4000">
</translate>
<!--
xml移动动画: 从屏幕的右边逐渐回到原来的位置, 持续2s
-->set_test.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<alpha android:fromAlpha="0"

android:pivotX="50%"
android:pivotY="50%"/>
</set>
<!--
Xml复合动画: 透明度从透明到不透明, 持续2s, 接着进行旋转360度的动画, 持续2s
-->
startActivity(new Intent(this, DAActivity.class));
先看布局文件
