威哥工作中，需要再EditText文本框下展示数字软键盘，用于输入数字。效果图如下：

威哥从来都是一个直来直去的人，直接上代码实现，大家借鉴借鉴，自行修改。

1.xml布局popup\_number.xml：

<?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

            android:layout_width="fill_parent"
            android:layout_height="match_parent"

                    }
                    break;
                case R.id.tv_NumberPopup_0:
                    if (listener != null) {
                        listener.onChooseNum(tv_NumberPopup_0.getText().toString());
                    }
                    break;
                case R.id.iv_NumberPopup_Del:  //删除按钮
                    if (listener != null) {
                        listener.onDelNum();
                    }
                    break;
                case R.id.iv_NumberPopup_Sure:
                    if (listener != null) {
                        listener.onSureNum();
                        dismiss();
                    }
                    break;
                default:
                    break;
            }
        }
    
        private NumberPopup.AddListener listener = null;
    
        public void setListener(NumberPopup.AddListener listener) {
            this.listener = listener;
        }
    
        /**
         * 申明监听接口
         * Author：William（徐威）
         * Create Time：2018-10-18
         */
        public interface AddListener {
            //选择数字事件
            void onChooseNum(String strNum);
    
            //删除数字事件
            void onDelNum();
    
            //确认数字事件
            void onSureNum();
        }
    }

3、Activity中使用：

private EditText etxt_ProductCart_SearchProduct;    //  商品搜索框
    private NumberPopup popWindow;    //数组弹框对象

etxt_ProductCart_SearchProduct = this.findViewById(R.id.etxt_ProductCart_SearchProduct);
    etxt_ProductCart_SearchProduct.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View view, MotionEvent motionEvent) {
            if (popWindow != null) {
                popWindow.dismiss();
                popWindow = null;
            }
            popWindow = new NumberPopup(ProductCartActivity.this, mView, 0, 0);
            popWindow.showAtLocation(view, Gravity.TOP | Gravity.RIGHT, 0, 155);
            popWindow.setListener(new NumberPopup.AddListener() {
                /**
                 * 重写数组选择事件
                 * Author：William（徐威）
                 * Create Time：2018-10-18
                 * @param strNum
                 */
                @Override
                public void onChooseNum(String strNum) {
                    String strProductId = etxt_ProductCart_SearchProduct.getText().toString();
                    etxt_ProductCart_SearchProduct.setText(String.format("%s%s", strProductId, strNum));
                    returnOld();
                }
    
                /**
                 * 重写数字删除事件
                 * Author：William（徐威）
                 * Create Time：2018-10-18
                 */
                @Override
                public void onDelNum() {
                    String strProductId = etxt_ProductCart_SearchProduct.getText().toString();
                    if(!TextUtils.isEmpty(strProductId)){
                        etxt_ProductCart_SearchProduct.setText(strProductId.substring(0, strProductId.length() - 1));
                    }
                    returnOld();
                }
    
                @Override
                public void onSureNum() {
                    searProduct();
                }
            });
            return false;
        }
    });

希望大家能够有所帮助。平方的威哥。。。
