使用ViewFlipper写自动上下滚动的数据

使用ViewFlipper写自动上下滚动的数据

重写ViewFlipper，为其添加动画

public class MyViewFlipper extends ViewFlipper {
    private Context mContext;
    //是否设置动画
    private boolean isSetAnimDuration = false;
    //设置数据展示时间
    private int interval = 3000;
    /**
     * 动画时间
     */
    private int animDuration = 300;

    public MyViewFlipper(Context context, AttributeSet attrs) {
        super(context, attrs);
        init(context, attrs, 0);
    }

    private void init(Context context, AttributeSet attrs, int defStyleAttr) {
        this.mContext = context;
        setFlipInterval(interval);
        Animation animIn = AnimationUtils.loadAnimation(mContext,
                R.anim.anim_marquee_in);
        if (isSetAnimDuration)
            animIn.setDuration(animDuration);
        setInAnimation(animIn);
        Animation animOut = AnimationUtils.loadAnimation(mContext,
                R.anim.anim_marquee_out);
        if (isSetAnimDuration)
            animOut.setDuration(animDuration);
        setOutAnimation(animOut);
    }

    /**
     * 设置循环滚动的View数组
     * 
     * @param views
     */
    public void setViews(List views) {
        if (views == null || views.size() == 0)
            return;
        removeAllViews();
        for (int i = 0; i < views.size(); i++) {
            addView(views.get(i));
        }
        if (views.size()>1) {
            startFlipping();
        }else {
            stopFlipping();
        }
    }

}

数据进入动画

 <translate
        android:duration="1500"
        android:fromYDelta="100%p"
        android:toYDelta="0" >
    translate>

数据出去动画

<translate
        android:duration="1500"
        android:fromYDelta="0"
        android:toYDelta="-100%p" >
    translate>

数据加载使用

ViewFlipper.setViews(views);
