[转]Android：改变Activity切换方式

overridePendingTransition(enterAnim, exitAnim);

Intent intent =new Intent(this,item2.class);
startActivity(intent);
this.finish();
overridePendingTransition(android.R.anim.slide_in_left,android.R.anim.slide_out_right); 

要整个应用改切换方式的话，那就用style控制吧

1、在res文件夹创建anim文件夹

2、添加以下文件：

slide_left_in.xml  从左边进来

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
    <translate
        android:duration="200"
        android:fromXDelta="-100.0%p"
        android:toXDelta="0.0" />

</set>

slide_left_out.xml 从左边出去

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >

    <translate
        android:duration="200"
        android:fromXDelta="0.0"
        android:toXDelta="-100.0%p" />

</set>

slide_right_in.xml 从右边进来

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >

    <translate
        android:duration="200"
        android:fromXDelta="100.0%p"
        android:toXDelta="0.0" />

</set>

slide_right_out.xml  从右边出去

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >

    <translate
        android:duration="200"
        android:fromXDelta="0.0"
        android:toXDelta="100.0%p" />

</set>

属性讲解：

translate 位置转移动画效果

android:fromXDelta="0" -----------从0坐标开始开始
android:toXDelta="-100%p" ------移动距离到父层的-100%

两个参数都是指控件相对于parent的偏移距离

android:duration="200" -----------持续时间

3、修改主题样式

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

    <style name="activityAnimation" parent="@android:style/Animation">
        <item name="android:activityOpenEnterAnimation">@anim/slide_right_in</item>
        <item name="android:activityOpenExitAnimation">@anim/slide_left_out</item>
        <item name="android:activityCloseEnterAnimation">@anim/slide_left_in</item>
        <item name="android:activityCloseExitAnimation">@anim/slide_right_out</item>
    </style>
