比較簡單的一個控制項,就是加些邏輯處理而已,以前貌似是直接監聽的,封裝起來方便點
public class AccountTxtView extends android.support.v7.widget.AppCompatEditText { private final char CUT = '-'; public AccountTxtView(Context context) { super(context); } public AccountTxtView(Context context, AttributeSet attrs) { super(context, attrs); } public AccountTxtView(Context context, AttributeSet attrs, int defStyleAttr) { super(context, attrs, defStyleAttr); } @Override protected void onTextChanged(CharSequence text, int start, int lengthBefore, int lengthAfter) { if (text == null || text.length() == 0) return; StringBuilder sb = new StringBuilder(); for (int i = 0; i < text.length(); i++) {//添加分割符 if (i != 3 && i != 8 && text.charAt(i) == CUT) { continue; } else { sb.append(text.charAt(i)); if ((sb.length() == 4 || sb.length() == 9) && sb.charAt(sb.length() - 1) != CUT) { sb.insert(sb.length() - 1, CUT); } } } //防止多次設置值 if (!sb.toString().equals(text.toString())) { int index = start + 1; if (sb.charAt(start) == CUT) { if (lengthBefore == 0) { index++; } else { index--; } } else { if (lengthBefore == 1) { index--; } } setText(sb.toString()); setSelection(index); }else{//刪除時候判斷 String line = text.subSequence(text.length() - 1, text.length()).toString(); if (line.equals(String.valueOf(CUT))) {//如果刪除碰到‘-’符號,則預設去除 sb.deleteCharAt(text.subSequence(0, text.length() - 1).length()); setText(sb.toString()); setSelection(sb.length()); } } } public String getPhone() { String result = null; String val = getText().toString(); if (val == null || val.isEmpty()) return ""; result = val.replace(String.valueOf(CUT), ""); return result; } }View Code
使用也簡單
然後效果就出來了
輸入第四個的時候自動填充‘-’分隔符,然後刪除的時候自動刪除‘-’分隔符
