150 | > ### 实现原理
151 |
152 | 首先通过`LayoutInflater.from`获取到layout,然后`findViewById`拿到里面的控件，这里用了三个控件`EditText,TextView,View`,View是最下面的横线
153 |
154 | ```
155 | LayoutInflater.from(context).inflate(R.layout.anfq_num_edittext, this, true);
156 | etContent = (EditText) findViewById(R.id.etContent);
157 | tvNum = (TextView) findViewById(R.id.tvNum);
158 | vLine = findViewById(R.id.vLine);
159 | ```
160 |
161 | 然后提供一些设置值的方法，如右下角的类型（这里有两种类型，即：单数类型和百分比类型）、最大字符的长度、EditText的Hint、横线的颜色。
162 |
163 | 设置`EditText`的监听TextWatcher（这里是参考了网上的一些代码，具体链接找不到了）
164 |
165 | ```
166 | public void afterTextChanged(Editable s) {
167 | editStart = etContent.getSelectionStart();
168 | editEnd = etContent.getSelectionEnd();
169 | // 先去掉监听器，否则会出现栈溢出
170 | etContent.removeTextChangedListener(mTextWatcher);
171 | // 注意这里只能每次都对整个EditText的内容求长度，不能对删除的单个字符求长度
172 | // 因为是中英文混合，单个字符而言，calculateLength函数都会返回1
173 |
174 | // 当输入字符个数超过限制的大小时，进行截断操作
175 | while (calculateLength(s.toString()) > MaxNum) {
176 | s.delete(editStart - 1, editEnd);
177 | editStart--;
178 | editEnd--;
179 | }
180 | // 恢复监听器
181 | etContent.addTextChangedListener(mTextWatcher);
182 | setLeftCount();
183 | }
184 |
185 | /** 刷新剩余输入字数 */
186 | private void setLeftCount() {
187 | if(TYPES.equals(SINGULAR)){//类型1
188 | tvNum.setText(String.valueOf((MaxNum - getInputCount())));
189 | }else if(TYPES.equals(PERCENTAGE)){//类型2
190 | tvNum.setText(MaxNum-(MaxNum - getInputCount())+"/"+MaxNum);
191 | }
192 | }
193 | /** 获取用户输入内容字数 */
194 | private long getInputCount() {
195 | return calculateLength(etContent.getText().toString());
196 | }
197 | /**
198 | * 计算分享内容的字数，一个汉字=两个英文字母，一个中文标点=两个英文标点
199 | * 注意：该函数的不适用于对单个字符进行计算，因为单个字符四舍五入后都是1
200 | * @param cs
201 | * @return
202 | */
203 | public static long calculateLength(CharSequence cs) {
204 | double len = 0;
205 | for (int i = 0; i < cs.length(); i++) {
206 | int tmp = (int) cs.charAt(i);
207 | if (tmp > 0 && tmp < 127) {
208 | len += 1;
209 | } else {
210 | len++;
211 | }
212 | }
213 | return Math.round(len);
214 | }
215 | }
216 | ```
217 |
218 | > ### 总结
219 | > 这种EditText显示输入字数的控件在开发中经常用到，但是如果在多个地方用到的话都要做监听代码重复太多，所以做了一下封装，以便以后使用
