效果：

代码：

public class SelectDialog extends BaseDialog {

    private OnSelectListener selectListener;
    private List dataList;
    private WheelVerticalView wheel_select;
    private TextView tv_cancel;
    private RelativeLayout rl_select_layout;

    public SelectDialog(Context context) {
        super(context);
    }

    public SelectDialog(Context context, List dataList, boolean canceledOnTouchOutside, OnSelectListener selectListener) {
        super(context, canceledOnTouchOutside);
        this.dataList = dataList;
        this.selectListener = selectListener;
    }

    @Override

        tv_cancel = (TextView) rootView.findViewById(R.id.tv_cancel);
        rl_select_layout = (RelativeLayout) rootView.findViewById(R.id.rl_select_bankcard_layout);
        tv_cancel.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                SelectDialog.this.dismiss();
            }
        });
        rl_select_layout.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                SelectDialog.this.dismiss();

                SelectDialog.this.dismiss();
            }
        });
        getWindow().setWindowAnimations(R.style.anim_bottom_alpha);
    }

    @Override

        wheel_select.setViewAdapter(new ArrayWheelAdapter<>(mContext, R.layout.item_select_dialog, R.id.tv_content, dataList));
    }

    public void setSelection(int position) {
        wheel_select.setCurrentItem(position);
    }

    public interface OnSelectListener {
        void onSelect(int position);
    }

    private static class ArrayWheelAdapter extends AbstractWheelTextAdapter {
        private List items;

        public ArrayWheelAdapter(Context context, int itemResource, int itemTextResource, List items) {
            super(context, itemResource, itemTextResource);
            this.items = items;
        }

        @Override

                }
                return item.toString();
            }
            return null;
        }

        @Override
        public int getItemsCount() {
            return items.size();
        }
    }
}

布局：dlg_select.xml

布局：item_select_dialog.xml

使用：

SelectDialog dialog = new SelectDialog(context, relationList, true, new SelectDialog.OnSelectListener() {
                    @Override
                    public void onSelect(int position) {
                        mFrtRelationWithProposer.setText(relationList.get(position));
                    }
                });
dialog.show();
