Android 循环滚动控件ViewFlipper，可实现跑马灯或轮播图效果

2、实现方法

（1）创建进出动画

上下滚动动画

y_in.xml

<?xml version="1.0" encoding="utf-8"?>

<set xmlns:android="http://schemas.android.com/apk/res/android">



    <translate

        android:fromYDelta="100%p"

        android:toYDelta="0"

        android:duration="1000"/>

</set>

y_out.xml

<?xml version="1.0" encoding="utf-8"?>

<set xmlns:android="http://schemas.android.com/apk/res/android">



    <translate

        android:fromYDelta="0"

        android:toYDelta="-100%p"

        android:duration="1000"/>

</set>

左右滚动动画

x_in.xml

<?xml version="1.0" encoding="utf-8"?>

<set xmlns:android="http://schemas.android.com/apk/res/android">



    <translate

        android:fromXDelta="100%p"

        android:toXDelta="0"

        android:duration="1000"/>

</set>

x_out.xml

<?xml version="1.0" encoding="utf-8"?>

<set xmlns:android="http://schemas.android.com/apk/res/android">



    <translate

        android:fromXDelta="0"

        android:toXDelta="-100%p"

        android:duration="1000"/>

</set>

（2）layout文件引用ViewFlipper

<ViewFlipper

    android:id="@+id/filpper"

    android:layout_width="match_parent"

    android:layout_height="wrap_content"

    android:autoStart="true"

    android:flipInterval="2000"

    android:inAnimation="@anim/x_in"

    android:outAnimation="@anim/x_out"/>

（3）activity中java代码实现ViewFlipper跑马灯效果

TextView textView;

ViewFlipper viewFlipper;

viewFlipper= (ViewFlipper) findViewById(R.id.filpper);

for (int i = 0; i < 5; i++) {

    View view = LayoutInflater.from(getApplicationContext()).inflate(R.layout.layout_custom, null);

    textView = view.findViewById(R.id.myte1);

    textView.setText("sssssssss===="+i);



    viewFlipper.addView(view);

}
