[英]getting phone number in XXX-XXX-XXXX format from edittext box in android
Hi I am writing an android in which user enters phone number in an edit text box.嗨,我正在写一个 android,其中用户在编辑文本框中输入电话号码。 I want the number to be in the form of xxx-xxx-xxxx that means '-' should come automatically after user enters first 3 letters and another '-'
我希望数字采用 xxx-xxx-xxxx 的形式,这意味着在用户输入前 3 个字母和另一个 '-' 后,'-' 应该自动出现
I used EditText anum= (EditText)findViewById(R.id.altnum); anum.addTextChangedListener(new PhoneNumberFormattingTextWatcher());
我用
EditText anum= (EditText)findViewById(R.id.altnum); anum.addTextChangedListener(new PhoneNumberFormattingTextWatcher());
EditText anum= (EditText)findViewById(R.id.altnum); anum.addTextChangedListener(new PhoneNumberFormattingTextWatcher());
but it is coming into format only after all the digits are entered.但只有在输入所有数字后才会进入格式。 I want the change to come when the user was entering the data like if he press 123 a hypen should come automatically Please tell me how to do this.
我希望在用户输入数据时进行更改,例如如果他按 123,hypen 应该会自动出现请告诉我该怎么做。
Thanking You感谢您
Yours Sincerely此致

Recently, I had a requirement for the same.最近,我也有同样的要求。 I tried this with TextWatcher.
我用 TextWatcher 试过这个。 Sharing here with a hope that Someone else may need later.
在这里分享,希望其他人以后可能需要。
public class PhoneNumberTextWatcher implements TextWatcher {
private static final String TAG = PhoneNumberTextWatcher.class
.getSimpleName();
private EditText edTxt;
private boolean isDelete;
public PhoneNumberTextWatcher(EditText edTxtPhone) {
this.edTxt = edTxtPhone;
edTxt.setOnKeyListener(new OnKeyListener() {
@Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_DEL) {
isDelete = true;
}
return false;
}
});
}
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}
public void afterTextChanged(Editable s) {
if (isDelete) {
isDelete = false;
return;
}
String val = s.toString();
String a = "";
String b = "";
String c = "";
if (val != null && val.length() > 0) {
val = val.replace("-", "");
if (val.length() >= 3) {
a = val.substring(0, 3);
} else if (val.length() < 3) {
a = val.substring(0, val.length());
}
if (val.length() >= 6) {
b = val.substring(3, 6);
c = val.substring(6, val.length());
} else if (val.length() > 3 && val.length() < 6) {
b = val.substring(3, val.length());
}
StringBuffer stringBuffer = new StringBuffer();
if (a != null && a.length() > 0) {
stringBuffer.append(a);
if (a.length() == 3) {
stringBuffer.append("-");
}
}
if (b != null && b.length() > 0) {
stringBuffer.append(b);
if (b.length() == 3) {
stringBuffer.append("-");
}
}
if (c != null && c.length() > 0) {
stringBuffer.append(c);
}
edTxt.removeTextChangedListener(this);
edTxt.setText(stringBuffer.toString());
edTxt.setSelection(edTxt.getText().toString().length());
edTxt.addTextChangedListener(this);
} else {
edTxt.removeTextChangedListener(this);
edTxt.setText("");
edTxt.addTextChangedListener(this);
}
}
}
Thanks谢谢

Following Code works adding and deleting scenario's fine but logic is some what longer:以下代码可以很好地添加和删除场景,但逻辑要长一些:
public class PhoneNumberTextWatcher implements TextWatcher {
private static final String TAG = "PhoneNumberTextWatcher";
private EditText editText;
public PhoneNumberTextWatcher(EditText edTxtPhone) {
this.editText = edTxtPhone;
}
public void onTextChanged(CharSequence s, int cursorPosition, int before,
int count) {
if(before == 0 && count == 1){ //Entering values
String val = s.toString();
String a = "";
String b = "";
String c = "";
if (val != null && val.length() > 0) {
val = val.replace("-", "");
if (val.length() >= 3) {
a = val.substring(0, 3);
} else if (val.length() < 3) {
a = val.substring(0, val.length());
}
if (val.length() >= 6) {
b = val.substring(3, 6);
c = val.substring(6, val.length());
} else if (val.length() > 3 && val.length() < 6) {
b = val.substring(3, val.length());
}
StringBuffer stringBuffer = new StringBuffer();
if (a != null && a.length() > 0) {
stringBuffer.append(a);
}
if (b != null && b.length() > 0) {
stringBuffer.append("-");
stringBuffer.append(b);
}
if (c != null && c.length() > 0) {
stringBuffer.append("-");
stringBuffer.append(c);
}
editText.removeTextChangedListener(this);
editText.setText(stringBuffer.toString());
if(cursorPosition == 3 || cursorPosition == 7){
cursorPosition = cursorPosition+2;

cursorPosition = cursorPosition+1;

}
editText.addTextChangedListener(this);
} else {
editText.removeTextChangedListener(this);
editText.setText("");
editText.addTextChangedListener(this);
}
}
if(before == 1 && count == 0){ //Deleting values
String val = s.toString();
String a = "";
String b = "";
String c = "";
if (val != null && val.length() > 0) {

One option is to implement your own InputFilter .一种选择是实现您自己的InputFilter 。
You can use my answers here: press "."你可以在这里使用我的答案: 按“。” many times (validate ip address in EditText while typing) and here: How to set Edittext view allow only two numeric values and two decimal values like ##.## for examples on how to parse the text while typing.
多次(在键入时在 EditText 中验证 ip 地址)和此处: 如何设置 Edittext 视图仅允许两个数字值和两个十进制值,例如 ##.## ,例如如何在键入时解析文本。
If you want the dashes to appear automatically, you will need to add them to the return of your filter method如果您希望破折号自动出现,您需要将它们添加到您的过滤器方法的返回
