去除系统自带统一应用动画

方法一:

在startActivity()或者finish()后紧跟调用:

((Activity) mContext).overridePendingTransition(0, 0);

方法二:

比如给Intent设置了属性:

intent.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);

此时可以这么做:

1 在styles.xml下添加:

<resources>
    <!--
        Base application theme, dependent on API level. This theme is replaced
        by AppBaseTheme from res/values-vXX/styles.xml on newer devices.
    -->
        <style name="AppBaseTheme" parent="@android:style/Theme.Black.NoTitleBar.Fullscreen">
        <item name="android:windowAnimationStyle">@style/myAnimation</item>
    </style>

    <!-- Application theme. -->
    <style name="AppTheme" parent="AppBaseTheme">
        <!-- All customizations that are NOT specific to a particular API-level can go here. -->
    </style>

    <style name="myAnimation">  
        <item name="android:activityOpenEnterAnimation">@anim/anim_in</item>  
       <item name="android:activityOpenExitAnimation">@anim/anim_in</item>  
       <item name="android:activityCloseEnterAnimation">@anim/anim_out</item>  
       <item name="android:activityCloseExitAnimation">@anim/anim_out</item> 
       <item name="android:windowEnterAnimation">@anim/anim_in</item>
        <item name="android:windowExitAnimation">@anim/anim_out</item>
        <item name="android:taskToFrontEnterAnimation">@anim/anim_in</item>  
    	<item name="android:taskToFrontExitAnimation">@anim/anim_out</item>  
    	<item name="android:taskToBackEnterAnimation">@anim/anim_in</item>  
    	<item name="android:taskToBackExitAnimation">@anim/anim_out</item>  
    	<item name="android:taskOpenEnterAnimation">@anim/anim_in</item>  
        <item name="android:taskOpenExitAnimation">@anim/anim_out</item>
        <item name="android:taskCloseEnterAnimation">@anim/anim_in</item>
        <item name="android:taskCloseExitAnimation">@anim/anim_out</item> 
    </style> 
</resources>

2 在AndroidManifest.xml中为跳出和跳入的Activity设置，如果要统一应用全局动画，可以设置application的theme:

android:theme="@style/AppTheme"
