    popupWindow.update();
    popupWindow.showAsDropDown(mBtnShow, DisplayUtils.dip2px(this, 50), 15);
    mListViewAdapter = new ListViewAdapter(this,mData,popupWindow);
    mPopListView.setAdapter(mListViewAdapter);
}

            convertView.setTag(viewHolder);
        } else {
            viewHolder = (ViewHolder) convertView.getTag();
        }
        viewHolder.mTextView.setText(mData.get(position));
        viewHolder.mTextView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                ToastUtils.showToast(mContext, mData.get(position));//在此处进行点击事件
                mPopupWindow.dismiss();
            }
        });
        return convertView;
    }

    static class ViewHolder {
        TextView mTextView;
    }
}

布局就没啥可贴的了。
