1.实现监听

 editext1.addTextChangedListener(new PhoneTextWatcher(editext1));

2.监听类实现

package alldemo.renlin.com.androiddemo.tool;import android.text.Editable;import android.text.TextWatcher;import android.widget.EditText;/** * Created by Administrator on 2017/5/31. */public class PhoneTextWatcher implements TextWatcher {    private EditText _text;    public PhoneTextWatcher(EditText _text) {        this._text = _text;    }    @Override    public void beforeTextChanged(CharSequence s, int start, int count, int after) {    }    @Override    public void onTextChanged(CharSequence s, int start, int before, int count) {        if (s == null || s.length() == 0) return;        StringBuilder sb = new StringBuilder();        for (int i = 0; i < s.length(); i++) {            if (i != 3 && i != 8 && s.charAt(i) == ' ') {                continue;            } else {                sb.append(s.charAt(i));                if ((sb.length() == 4 || sb.length() == 9) && sb.charAt(sb.length() - 1) != ' ') {                    sb.insert(sb.length() - 1, ' ');                }            }        }        if (!sb.toString().equals(s.toString())) {            int index = start + 1;            if (sb.charAt(start) == ' ') {                if (before == 0) {                    index++;                } else {                    index--;                }            } else {                if (before == 1) {                    index--;                }            }            _text.setText(sb.toString());            _text.setSelection(index);        }    }    @Override    public void afterTextChanged(Editable s) {    }}
