一:整个app都采用淡入淡出效果
1:在anim文件夹下定义动画文件
accelerate_interpolator.xml
<span style="font-size:14px;"><?xml version="1.0" encoding="utf-8"?> <accelerateInterpolator /></span>
decelerate_interpolator.xml
<span style="font-size:14px;"><?xml version="1.0" encoding="utf-8"?> <decelerateInterpolator /></span>
fade_in.xml
<span style="font-size:14px;"><?xml version="1.0" encoding="utf-8"?> <alpha xmlns:android="http://schemas.android.com/apk/res/android" android:duration="@android:integer/config_longAnimTime" android:fromAlpha="0.0" android:interpolator="@anim/decelerate_interpolator" android:toAlpha="1.0" /></span>
fade_out.xml
<span style="font-size:14px;"><?xml version="1.0" encoding="utf-8"?> <alpha xmlns:android="http://schemas.android.com/apk/res/android" android:duration="@android:integer/config_mediumAnimTime" android:fromAlpha="1.0" android:interpolator="@anim/accelerate_interpolator" android:toAlpha="0.0" /></span>
2:定义styles.xml文件
<span style="font-size:14px;"><resources xmlns:android="http://schemas.android.com/apk/res/android"> <style name="AppBaseTheme" parent="android:Theme.Light"></style> <style name="AppTheme" parent="AppBaseTheme"> <item name="android:windowAnimationStyle">@style/MyAnimation</item> </style> <style name="MyAnimation" parent="@android:style/Animation.Activity"> <item name="android:activityOpenEnterAnimation">@anim/fade_in</item> <item name="android:activityOpenExitAnimation">@anim/fade_out</item> <item name="android:activityCloseEnterAnimation">@anim/fade_in</item> <item name="android:activityCloseExitAnimation">@anim/fade_out</item> </style> </resources></span>
3.在配置文件下配置主题
<span style="font-size:14px;"><application android:allowBackup="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <activity android:name="com.union.foodunion.WelcomeActivity" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application></span>
二:单个页面采用淡入淡出效果
在anim文件夹下定义动画文件(同上),然后在Actiivty中finish()或startActivity()后加一下代码:
<span style="font-size:14px;">overridePendingTransition(R.anim.fade_in, R.anim.fade_out);</span>
android 动画切换效果
