EditText电话号码格式化输入、删除案例

    我们在输入电话号码的时候，一般都会分割一个较长的电话号码，这样的话效果会好很多。。对EditText的监听可以轻松的实现这个需求，只需要我们给对应的EditText加一个监听就OK了。。贴一下我写的一个watcher

public static class MyTextWatcher implements TextWatcher {

		private EditText numberEditText;
		private Button confirmButton;
		int beforeLen = 0;
		int afterLen = 0;

		public MyTextWatcher(EditText numberEditText, Button confirmButton) {
			this.numberEditText = numberEditText;
			this.confirmButton = confirmButton;
		}

		@Override
		public void onTextChanged(CharSequence s, int start, int before,
				int count) {
		}

		@Override
		public void beforeTextChanged(CharSequence s, int start, int count,
				int after) {
			beforeLen = s.length();
		}

		@Override
		public void afterTextChanged(Editable s) {
			String txt = numberEditText.getText().toString();
			afterLen = txt.length();

			if (afterLen > beforeLen) {
				if (txt.length() == 4 || txt.length() == 9) {
					numberEditText.setText(new StringBuffer(txt).insert(
							txt.length() - 1, " ").toString());
					numberEditText.setSelection(numberEditText.getText()
							.length());
				}
			} else {
				if (txt.startsWith(" ")) {
					numberEditText.setText(new StringBuffer(txt).delete(
							afterLen - 1, afterLen).toString());
					numberEditText.setSelection(numberEditText.getText()
							.length());

				}
			}

		}
	}

使用的时候只需要new 这个watcher，传入当前的Edittext即可
