android 動畫轉場效果

標籤：動畫   android   切換   效果   

一:整個app都採用淡入淡出效果1:在anim檔案夾下定義動畫檔案

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:定義styles.xml檔案

<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.在設定檔下配置主題

<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:單個頁面採用淡入淡出效果在anim檔案夾下定義動畫檔案(同上),然後在Actiivty中finish()或startActivity()後加一下代碼:

<span style="font-size:14px;">overridePendingTransition(R.anim.fade_in, R.anim.fade_out);</span>
