跑马灯 View，支持自定义跑马灯 ItemView。

效果图

使用

Gradle:

compile 'com.gongwen:marqueelibrary:1.1.2'

属性

MarqueeView 属性

SimpleMarqueeView 属性(支持 MarqueeView 所有属性及以下属性)

用法一：使用 SimpleMarqueeView 和 SimpleMF

XML

<com.gongwen.marqueen.SimpleMarqueeView
    android:id="@+id/simpleMarqueeView"
    android:layout_width="match_parent"
    android:layout_height="40dp"
    android:flipInterval="2500"
    android:inAnimation="@anim/in_right"
    android:outAnimation="@anim/out_left"
    app:marqueeAnimDuration="2000"
    app:smvTextColor="@color/white"
    app:smvTextGravity="center_vertical"
    app:smvTextSize="15sp"></com.gongwen.marqueen.SimpleMarqueeView>

设置数据

SimpleMarqueeView marqueeView = (SimpleMarqueeView) findViewById(R.id.marqueeView);
final List<String> datas = Arrays.asList("《赋得古原草送别》", "离离原上草，一岁一枯荣。", "野火烧不尽，春风吹又生。", "远芳侵古道，晴翠接荒城。", "又送王孙去，萋萋满别情。");
SimpleMF<String> marqueeFactory = new SimpleMF(this);
marqueeFactory.setData(datas);
marqueeView.setMarqueeFactory(marqueeFactory);
marqueeView.startFlipping();

设置事件监听

marqueeFactory.setOnItemClickListener(new MarqueeFactory.OnItemClickListener<TextView, String>() {
    @Override
    public void onItemClickListener(MarqueeFactory.ViewHolder<TextView, String> holder) {
        Toast.makeText(MainActivity.this, holder.data, Toast.LENGTH_SHORT).show();
    }
});

用法二：自定义 MarqueeFactory 来设置不同类型 ItemView

XML

<com.gongwen.marqueen.MarqueeView
    android:id="@+id/marqueeView4"
    android:layout_width="match_parent"
    android:layout_height="40dp"
    android:flipInterval="2500"
    android:inAnimation="@anim/in_right"
    android:outAnimation="@anim/out_left"
    app:marqueeAnimDuration="2000"></com.gongwen.marqueen.MarqueeView>

自定义 MarqueeFactory

继承自 MarqueeFactory，通过泛型指定 ItemView 类型以及 ItemData 类型，之后实现 generateMarqueeItemView 方法，提供 ItemView，并为 ItemView 设置数据即可。

例如：

public class ComplexViewMF extends MarqueeFactory<RelativeLayout, ComplexItemEntity> {
    private LayoutInflater inflater;

    public ComplexViewMF(Context mContext) {
        super(mContext);
        inflater = LayoutInflater.from(mContext);
    }

    @Override
    public RelativeLayout generateMarqueeItemView(ComplexItemEntity data) {
        RelativeLayout mView = (RelativeLayout) inflater.inflate(R.layout.complex_view, null);
        ((TextView) mView.findViewById(R.id.title)).setText(data.getTitle());
        ((TextView) mView.findViewById(R.id.secondTitle)).setText(data.getSecondTitle());
        ((TextView) mView.findViewById(R.id.time)).setText(data.getTime());
        return mView;
    }
}

设置数据和事件监听用法同上

重影问题可参考以下解决方案(参考自这里)

@Override
public void onStart() {
    super.onStart();
    marqueeView.startFlipping();
}

@Override public void onStop() { super.onStop(); marqueeView.stopFlipping(); }
