动画类型
Android的animation由四种类型组成
XML中
alpha : 渐变透明度动画效果
scale :渐变尺寸伸缩动画效果
translate : 画面转换位置移动动画效果
rotate :画面转移旋转动画效果
Java代码中
AlphaAnimation : 渐变透明度动画效果
ScaleAnimation :渐变尺寸伸缩动画效果
TranslateAnimation : 画面转换位置移动动画效果
RotateAnimation :画面转移旋转动画效果
1、main.xml
<?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" > <LinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="horizontal" > <Button android:id="@+id/rotateButton" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="旋转" /> <Button android:id="@+id/scaleButton" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="缩放" /> <Button android:id="@+id/alphaButton" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="淡入淡出" /> <Button android:id="@+id/translateButton" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="移动" /> </LinearLayout> <LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <ImageView android:id="@+id/image" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerInParent="true" android:src="@drawable/an" /> </LinearLayout> </LinearLayout>
2、.java文件
