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>
