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：

<?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）：

 

<?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：

 

 

<?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>

MAinActivity：

        spinner.setAdapter(adapter);
        spinner.setOnItemSelectedListener(this);

        mFirstFragment=new BlankFragment();

        getFragmentManager().beginTransaction()
                .add(R.id.fragment_place,mFirstFragment).commit();

    }

    public void addTransition(View view) {
        Button button = (Button) findViewById(R.id.button);
        if (getFragmentManager().getBackStackEntryCount() == 0) {
            BlankFragment2 fragment2 = new BlankFragment2();
            FragmentManager manager = getFragmentManager();
            FragmentTransaction transaction=manager.beginTransaction();

            fragmentTransactionExtended.addTransition(optionSelected);
            fragmentTransactionExtended.commit();
            button.setText("Back");
        }else{
