利用Android的ViewFlipper和AnimationUtils实现图片带有动画的轮播切换，其中当点击“上一张”图片时，切换到上一张图片；当点击“下一张”图片时，切换到下一张图片。其效果图如下：

设置布局文件，其内容如下：

activity_image_flipper_shade.xml

<"1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@drawable/background" android:paddingBottom="@dimen/activity_optopns_vertical_margin" android:paddingLeft="@dimen/activity_options_horizontal_margin" android:paddingRight="@dimen/activity_options_horizontal_margin" android:paddingTop="@dimen/activity_optopns_vertical_margin" tools:context=".ImageFlipperActivity" > <RelativeLayout android:id="@id/rl_image_flipper_shade_title" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal" > <Button android:id="@+id/btn_image_flipper_shade_back" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_marginBottom="10dp" android:background="@drawable/custom_button" android:text="@string/back" android:textColor="@color/textColor" android:textSize="16sp" android:visibility="visible" /> <TextView android:id="@id/tv_image_flipper_shade_title" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerInParent="true" android:text="@string/image_flipper_shade" android:textColor="@color/textColor" android:textSize="30sp" android:text /> </RelativeLayout> <LinearLayout android:id="@id/ll_image_flipper_shade_content" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_below="@id/rl_image_flipper_shade_title" android:layout_marginBottom="20dp" android:layout_marginTop="20dp" android:gravity="center" android:orientation="vertical" > <ViewFlipper android:id="@id/vf_image_flipper_shade" android:layout_width="match_parent" android:layout_height="match_parent" /> </LinearLayout> </RelativeLayout>

动画效果配置文件，其内容如下：

A.push_left_in.xml（从左边进入屏幕）

<"1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android" > <> <translate android:duration="500" android:fromXDelta="100%p" android:toXDelta="0" /> <> <alpha android:duration="500" android:fromAlpha="0.1" android:toAlpha="1.0" /> <> <> </set> B.push_left_out.xml（从左边退出屏幕） <"1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android" > <translate android:duration="500" android:fromXDelta="0" android:toXDelta="-100%p" /> <alpha android:duration="500" android:fromAlpha="1.0" android:toAlpha="0.1" /> </set> C.push_right_in.xml（从右边进入屏幕） <"1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android" > <translate android:duration="500" android:fromXDelta="-100%p" android:toXDelta="0" /> <alpha android:duration="500" android:fromAlpha="0.1" android:toAlpha="1.0" /> </set> D.push_right_out.xml（从右边退出屏幕） <"1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android" > <translate android:duration="500" android:fromXDelta="0" android:toXDelta="100%p" /> <alpha android:duration="500" android:fromAlpha="1.0" android:toAlpha="0.1" /> </set>

实现图片轮播切换的类为ImageFlipperShadeActivity.java，其内容为：

查字典教程网友情提醒大家需要注意事项如下：

需要设置WindowManager的属性，包含type、format和flags等等创建左右边图片动画加载效果，并实现onTouchEvent事件，其中MotionEvent.ACTION_DOWN为按下监听事件，MotionEvent.ACTION_UP为按下后松开事件

以上是本文给大家叙述的Android实现图片轮播切换实例代码，希望可以帮助到大家。
