MyBase类：

public class MyBase extends BaseAdapter {    Context context;    List<Bean.ResultBean.BookListBean> list;    private LayoutInflater mLayoutInflater;    private PopupWindow mpop;    private TextView delete;    private ImageView close;    public MyBase(Context context, List<Bean.ResultBean.BookListBean> list){        this.context = context;        this.list = list;        mLayoutInflater = LayoutInflater.from(context);        initPopView();    }    ImageOptions options = new ImageOptions.Builder()            .setLoadingDrawableId(R.mipmap.ic_launcher)            .setUseMemCache(true)            .setSize(200, 200)            .build();    public void more(List<Bean.ResultBean.BookListBean> lists, boolean flag) {        for (Bean.ResultBean.BookListBean bean : lists) {            if (flag) {                list.add(0, bean);            } else {                list.add(bean);            }        }    }    @Override    public int getCount() {        return list != null?list.size():0;    }    @Override    public Object getItem(int position) {        return list.get(position);    }    @Override    public long getItemId(int position) {        return position;    }    @Override    public View getView(int position, View convertView, ViewGroup parent) {        ViewHolder holder = null;        if (convertView == null) {            convertView = mLayoutInflater.inflate(R.layout.item,null);            holder = new ViewHolder();            holder.name = (TextView) convertView.findViewById(R.id.name);            holder.type = (TextView) convertView.findViewById(R.id.type);            holder.area = (TextView) convertView.findViewById(R.id.area);            holder.more = (ImageView) convertView.findViewById(R.id.more);            holder.img = (ImageView) convertView.findViewById(R.id.img);            convertView.setTag(holder);        } else {            holder = (ViewHolder) convertView.getTag();        }        holder.name.setText(list.get(position).getName());        holder.type.setText(list.get(position).getType());        holder.area.setText(list.get(position).getArea());        x.image().bind(holder.img, list.get(position).getCoverImg(),options);        holder.more.setOnClickListener(new PopAction(position));        return convertView;    }    class PopAction implements View.OnClickListener{        private int position;        public PopAction(int position) {            this.position = position;        }        @Override        public void onClick(View v) {            int[] array = new int[2];            v.getLocationOnScreen(array);            int x = array[0];            int y = array[1];            showPop(v, position, x, y);        }    }    private void initPopView(){        View popwindowLayout = mLayoutInflater.inflate(R.layout.popwindow,null);        mpop = new PopupWindow(popwindowLayout, ViewGroup.LayoutParams.WRAP_CONTENT,ViewGroup.LayoutParams.WRAP_CONTENT);        mpop.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#000000")));        mpop.setAnimationStyle(R.style.popWindowAnimation);        delete = (TextView) popwindowLayout.findViewById(R.id.delete_tv);        close = (ImageView) popwindowLayout.findViewById(R.id.close_iv);    }    private void showPop(View parent, final int position, int x, int y){        mpop.showAtLocation(parent,0,x,y);        mpop.setFocusable(true);        mpop.setOutsideTouchable(true);        delete.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                list.remove(position);                notifyDataSetChanged();                if(mpop.isShowing()){                    mpop.dismiss();                }            }        });        close.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                if(mpop.isShowing()){                    mpop.dismiss();                }            }        });    }    class ViewHolder {        TextView name;        TextView type;        TextView area;        ImageView img;        ImageView more;    }}

然后就在需要适配器的地方进行适配

Style：

<style name="popWindowAnimation" parent="@android:style/Animation">    <item name="android:windowEnterAnimation">@anim/right</item>    <item name="android:windowExitAnimation">@anim/left</item></style>

popwindow的动画：

<set xmlns:android="http://schemas.android.com/apk/res/android">    <translate        android:duration="300"        android:fromXDelta="0"        android:toXDelta="-100%p" /></set>

<set xmlns:android="http://schemas.android.com/apk/res/android">    <translate android:fromXDelta="100%p" android:toXDelta="0.0%p" android:duration="300"/></set>
