有多种fragment之间切换的效果,效果是这样的:
Demo的实现是很简单的。
在res/values中,新建一个arrays.xml文件,存放Fragment动画效果的名称,在spinner中使用:
[html] view plain copy
- <?xml version="1.0" encoding="utf-8"?>
- <resources>
- <string-array name="array_spinner">
- <item>SCALEX</item>
- <item>SCALEY</item>
- <item>SCALEXY</item>
- <item>FADE</item>
- <item>FLIP_HORIZONTAL</item>
- <item>FLIP_VERTICAL</item>
- <item>SLIDE_VERTICAL</item>
- <item>SLIDE_HORIZONTAL</item>
- <item>SLIDE_HORIZONTAL_PUSH_TOP</item>
- <item>SLIDE_VERTICAL_PUSH_LEFT</item>
- <item>GLIDE</item>
- <item>SLIDING</item>
- <item>STACK</item>
- <item>CUBE</item>
- <item>ROTATE_DOWN</item>
- <item>ROTATE_UP</item>
- <item>ACCORDION</item>
- <item>TABLE_HORIZONTAL</item>
- <item>TABLE_VERTICAL</item>
- <item>ZOOM_FROM_LEFT_CORNER</item>
- <item>ZOOM_FROM_RIGHT_CORNER</item>
- <item>ZOOM_SLIDE_HORIZONTAL</item>
- <item>ZOOM_SLIDE_VERTICAL</item>
- </string-array>
- </resources>
两个空的fragment的布局(都有一样):
[html] view plain copy
- <?xml version="1.0" encoding="utf-8"?>
- <com.desarrollodroide.libraryfragmenttransactionextended.SlidingRelativeLayout
- xmlns:android="http://schemas.android.com/apk/res/android"
- android:layout_width="match_parent"
- android:layout_height="match_parent"
- android:background="@drawable/back1" >
- <TextView
- android:layout_centerInParent="true"
- android:layout_width="wrap_content"
- android:layout_height="wrap_content"
- android:text="Fragment1"
- android:textColor="#FF009922"
- android:textSize="20dp"/>
- </com.desarrollodroide.libraryfragmenttransactionextended.SlidingRelativeLayout>
主部局:
[html] view plain copy
- <?xml version="1.0" encoding="utf-8"?>
- <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
- android:layout_width="match_parent"
- android:layout_height="match_parent"
- android:orientation="vertical">
- <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
- android:layout_width="match_parent"
- android:layout_height="wrap_content"
- android:orientation="horizontal">
- <Spinner
- android:layout_width="wrap_content"
- android:layout_height="wrap_content"
- android:layout_weight="1"
- android:id="@+id/spinner" />
- <Button
- android:id="@+id/button"
- android:layout_width="wrap_content"
- android:layout_height="wrap_content"
- android:onClick="addTransition"
- android:text="Push" />
- </LinearLayout>
- <com.desarrollodroide.libraryfragmenttransactionextended.SlidingRelativeLayout
- android:id="@+id/fragment_place"
- android:layout_marginLeft="10dp"
- android:layout_marginRight="10dp"
- android:layout_marginBottom="10dp"
- android:layout_marginTop="20dp"
- android:layout_width="match_parent"
- android:layout_height="match_parent">
- </com.desarrollodroide.libraryfragmenttransactionextended.SlidingRelativeLayout>
- </LinearLayout>
