android 手机号码显示加空格,Android实现输入手机号时自动添加空格

为了用户更好的体验,我们在输入手机号的时候 添加空格,方便用户查看是否输入错误,不多说代码上去

final EditText et_phone = (EditText) findViewById(R.id.et_phone);

et_phone.addTextChangedListener(new TextWatcher() {

@Override

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

if (count == 1){

int length = s.toString().length();

if (length == 3 || length == 8){

et_phone.setText(s + " ");

et_phone.setSelection(et_phone.getText().toString().length());

}

}

}

@Override

public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,

int arg3) {

}

@Override

public void afterTextChanged(Editable arg0) {

}

});
