Android FragmentTransactionExtended：使Fragment以多种样式动画切换

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：

1. <?xml version="1.0" encoding="utf-8"?>
2. <resources>
3. <string-array name="array_spinner">
4. <item>SCALEX</item>
5. <item>SCALEY</item>
6. <item>SCALEXY</item>
7. <item>FADE</item>
8. <item>FLIP_HORIZONTAL</item>
9. <item>FLIP_VERTICAL</item>
10. <item>SLIDE_VERTICAL</item>
11. <item>SLIDE_HORIZONTAL</item>
12. <item>SLIDE_HORIZONTAL_PUSH_TOP</item>
13. <item>SLIDE_VERTICAL_PUSH_LEFT</item>
14. <item>GLIDE</item>
15. <item>SLIDING</item>
16. <item>STACK</item>
17. <item>CUBE</item>
18. <item>ROTATE_DOWN</item>
19. <item>ROTATE_UP</item>
20. <item>ACCORDION</item>
21. <item>TABLE_HORIZONTAL</item>
22. <item>TABLE_VERTICAL</item>
23. <item>ZOOM_FROM_LEFT_CORNER</item>
24. <item>ZOOM_FROM_RIGHT_CORNER</item>
25. <item>ZOOM_SLIDE_HORIZONTAL</item>
26. <item>ZOOM_SLIDE_VERTICAL</item>
27. </string-array>
28. </resources>

两个空的fragment的布局（都有一样）：

1. <?xml version="1.0" encoding="utf-8"?>
2. <com.desarrollodroide.libraryfragmenttransactionextended.SlidingRelativeLayout
3. xmlns:android="http://schemas.android.com/apk/res/android"
4. android:layout_width="match_parent"
5. android:layout_height="match_parent"
6. android:background="@drawable/back1" >
7. <TextView
8. android:layout_centerInParent="true"
9. android:layout_width="wrap_content"
10. android:layout_height="wrap_content"
11. android:text="Fragment1"
12. android:textColor="#FF009922"
13. android:textSize="20dp"/>
14. </com.desarrollodroide.libraryfragmenttransactionextended.SlidingRelativeLayout>

主部局：

1. <?xml version="1.0" encoding="utf-8"?>
2. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
3. android:layout_width="match_parent"
4. android:layout_height="match_parent"
5. android:orientation="vertical">

10. <Spinner
11. android:layout_width="wrap_content"
12. android:layout_height="wrap_content"
13. android:layout_weight="1"
14. android:id="@+id/spinner" />
15. <Button
16. android:id="@+id/button"
17. android:layout_width="wrap_content"
18. android:layout_height="wrap_content"
19. android:onClick="addTransition"
20. android:text="Push" />
21. </LinearLayout>
22. <com.desarrollodroide.libraryfragmenttransactionextended.SlidingRelativeLayout

25. android:layout_marginRight="10dp"
26. android:layout_marginBottom="10dp"
