ViewFlipper自带轮播功能，可以设置间隔时间，item进去和退出的动画；

ViewFlipper添加需要滚动的view。

demo的思路：自定义ViewFlipper，初始化中设置它的滚动间隔时间，进去和结束的动画，然后在数据源的set方法中添加textview和imageview

public class MViewFlipper extends ViewFlipper {    OnCheckedListener onCheckedListener;    public void setOnCheckedListener(OnCheckedListener onCheckedListener) {        this.onCheckedListener = onCheckedListener;    }    Context mContext;    List<String> allData;    public interface OnCheckedListener {        void onClick(int position);    }    public MViewFlipper(Context context) {        super(context);    }    public MViewFlipper(Context context, AttributeSet attrs) {        super(context, attrs);        initView(context);    }    private void initView(Context context) {        mContext = context;        //间隔时间        setFlipInterval(3000);        //设置间隔        setPadding(5, 5, 5, 5);        //设置进入和出去的动画//出去的动画        AnimationSet animationSetOut = new AnimationSet(true);        AlphaAnimation alphaAnimation = new AlphaAnimation(1, 0);        // alphaAnimation.setStartOffset(500);        TranslateAnimation translateAnimation = new TranslateAnimation(getX(), getX(), 0, -100);        animationSetOut.addAnimation(translateAnimation);        animationSetOut.addAnimation(alphaAnimation);        animationSetOut.setDuration(1000);        setOutAnimation(animationSetOut);        //进来的动画        AnimationSet animationSetIn = new AnimationSet(true);        AlphaAnimation alphaAnimation1 = new AlphaAnimation(0, 1);        // alphaAnimation1.setStartOffset(500);设置延迟执行动画        TranslateAnimation translateAnimatio1n = new TranslateAnimation(getX(), getX(), 100, 0);        animationSetIn.addAnimation(translateAnimatio1n);        animationSetIn.addAnimation(alphaAnimation1);        animationSetIn.setDuration(1000);        setInAnimation(animationSetIn);    }    public void setAllData(List<String> allData) {        this.removeAllViews();        this.allData = allData;        //把数据添加到viewflipper里面        for (int i = 0; i < allData.size(); i++) {            TextView textView = new TextView(mContext);            final int finalI = i;            textView.setOnClickListener(new OnClickListener() {                @Override                public void onClick(View v) {                    onCheckedListener.onClick(finalI);                }            });            textView.setSingleLine();            textView.setTextSize(17.0f);            textView.setText(allData.get(i));            textView.setTextColor(Color.parseColor("#FF4081"));            textView.setGravity(Gravity.CENTER);            addView(textView, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));            ImageView imageView = new ImageView(mContext);            imageView.setBackgroundDrawable(getResources().getDrawable(R.mipmap.ic_launcher));            addView(imageView, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));        }    }}
