Android Some device text watcher not working and some are working

I have working on mention edit text in below code i am extracting text after typing # but this code in working in some device and not in some device.
I have uploaded both video of working and not working in which showing also that which text is getting in text-watcher in red colour in autocomplete list.
This is working video
This is not working video
Any one help me for getting out this problem .This code is working in some devices but in some devices.

Thanks.

For format Edit-text, below things can be helpful to you.
**Step 1** : Add following line in your build.gradle file
implementation 'com.github.pinball83:masked-edittext:1.0.4'
**Step 2 :** by xml :
<com.github.pinball83.maskededittext.MaskedEditText
android:id="#+id/masked_edit_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="number"
app:mask="8 (***) *** **-**"
app:notMaskedSymbol="*"
app:maskIcon="#drawable/abc_ic_clear_mtrl_alpha"
app:maskIconColor="#color/colorPrimary"
/>
or by java file :
MaskedEditText maskedEditText = new MaskedEditText.Builder(context)
.mask("8 (***) *** **-**")
.notMaskedSymbol("*")
.icon(R.drawable.ic_account_circle)
.iconCallback(unmaskedText -> { //Icon click callback handler })
.build();
MaskedEditText editText = new MaskedEditText.Builder(context)
.mask("8 (***) *** **-**")
.notMaskedSymbol("*")
.build();; //set mask to "8 (***) *** **-**" and not masked symbol to "*"
Text setup and formatting
MaskedEditText editText = new MaskedEditText..Builder(context)
.mask("8 (***) *** **-**")
.notMaskedSymbol("*")
.format("[1][2][3] [4][5][6]-[7][8]-[10][9]")//set format of returned data input into MaskedEditText
.build();
editText.setMaskedText("5551235567");
for more details use following url :
https://github.com/pinball83/Masked-Edittext
Enjoy :)

Step 1 : Create editText
<EditText
android:id="#+id/masked_edit_text"
android:layout_width="yourSize"
android:layout_height="yourSize"
android:inputType="textPassword"/>
Step2:
public class CustomTransformation extends PasswordTransformationMethod {
#Override
public CharSequence getTransformation(CharSequence source, View view) {
return new TransformedSequence(source);
}
private class TransformedSequence implements CharSequence {
private CharSequence sequence;
public TransformedSequence(CharSequence source) {
sequence = source; // Store char sequence
}
public char charAt(int index) {
return 'X'; // Replace with what you want.
}
public int length() {
return sequence.length(); // return the length
}
public CharSequence subSequence(int start, int end) {
return sequence.subSequence(start, end); //return sequence
}
}
Step 3: apply the transformation
EditText edittext = findViewById(R.id.masked_edit_text);
edittext.setTransformationMethod(new CustomTransformation());

try this library .
this will automatically mask your edittext with selected country number .

Issue while removing automatically added characters to custom PhoneNumberTextWatcher (XXX) XXX-XXXX

My code is working fine when formatting text in (XXX) XXX-XXXX format. But when removing characters, it stops once reached to character -/(). If I again put cursor to any number characters -/() will automatically get removed.
Here is code I used.
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 View.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("-", "");
val = val.replace("(", "");
val = val.replace(" ", "");
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) {
if (a.length() == 3) {
stringBuffer.append("("+a+")"+" ");
}
else{
stringBuffer.append(a);
}
}
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);
}
}
}

No need to listen for Delete key. Just store the previous value of edittext and compare it with new when afterTextChanged is called. Code below works great in my project. I have modified it for (XXX) XXX-XXXX format. You can modify the logic to specify when to delete special characters (, ) and -.
PhoneNumberTextWatcher:
public class PhoneNumberTextWatcher implements TextWatcher {
private EditText phoneNumberEditText;
private String phoneNumber = "";
public PhoneNumberTextWatcher(EditText editText) {
phoneNumberEditText = editText;
}
#Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {}
#Override
public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {}
#Override
public void afterTextChanged(Editable s) {
String newValue = s.toString();
if (newValue.length() > phoneNumber.length()) {
phoneNumber = s.toString();
if (phoneNumber.length() == 4) {
if ('(' != phoneNumber.charAt(0)) {
phoneNumberEditText.setText("(" + phoneNumber.substring(0, phoneNumber.length() - 1) + ") " + phoneNumber.substring(phoneNumber.length() - 1));
phoneNumberEditText.setSelection(phoneNumber.length());

How to call text Watcher when user update any value from edit text

i have button,on button click it create editText with value, value of edit text is depending on count of total edit texts.for example edittext1 = 100, when user create two edit text then the value will be like this edittext1 = 50,edittext2 = 50 and so on.( value = 100/ total no of edittext) which i set equally to each edit text.now the problem is when user want to change/update any value from edittext, i want to update value of each edittext according to user's newly entered value.
i want to call textwatcher when value changed by only user,in my case when user click on button it will call.
thank you.

how to parse values in my constructor?

I created one constructor class I need all attributes values so I am trying to parse value in my constructor class but i am getting null value. so please help me how to get value? i am spending more time in this concept
This is my code:
public void test(NodeList panelNodes) {
Region RegionOptions = new Region(this.getApplicationContext());
RegionOptions.updateValues(RegionOptions.left);
for (int i = 0; i < panelNodes.getLength()-1; i++) {
Element panelElement = (Element) panelNodes.item(i);
NamedNodeMap nod=panelElement.getAttributes();
String layout=panelNodes.item(i).getNodeName();
if(layout.compareTo("region") == 0) {
for(int k=0;k<nod.getLength();k++){
Node nd=nod.item(k);
//System.out.println(layout+":"+ nd.getNodeName()+"::"+nd.getNodeValue());
if(nd.getNodeName().compareTo("left") == 0) {
RegionOptions.left = Integer.parseInt(nd.getNodeValue());
}else if(nd.getNodeName().compareTo("top") == 0) {
RegionOptions.top = Integer.parseInt(nd.getNodeValue());
}else if(nd.getNodeName().compareTo("height") == 0) {
RegionOptions.height = Integer.parseInt(nd.getNodeValue());
}else if(nd.getNodeName().compareTo("width") == 0) {
RegionOptions.width = Integer.parseInt(nd.getNodeValue());
}else if(nd.getNodeName().compareTo("userId") == 0) {
RegionOptions.userId = Integer.parseInt(nd.getNodeValue());
}else if(nd.getNodeName().compareTo("id") == 0) {
RegionOptions.id = nd.getNodeValue();
} else {
System.out.println("Unknown Tag:" + layout+":"+ nd.getNodeName()+"::"+nd.getNodeValue());
}
}
//return(RegionOptions.userId, RegionOptions.bgcolor, RegionOptions.duration);
}
if(layout.compareTo("media") == 0) {
for(int l=0;l<nod.getLength();l++){
Node nd=nod.item(l);
//System.out.println(layout+":"+ nd.getNodeName()+"::"+nd.getNodeValue());
if(nd.getNodeName().compareTo("type") == 0) {
RegionOptions.type = nd.getNodeValue();
}else if(nd.getNodeName().compareTo("duration") == 0) {
RegionOptions.duration = Integer.parseInt(nd.getNodeValue());
}else if(nd.getNodeName().compareTo("lkid") == 0) {
RegionOptions.lkid = Integer.parseInt(nd.getNodeValue());
}else if(nd.getNodeName().compareTo("userId") == 0) {
RegionOptions.userId = Integer.parseInt(nd.getNodeValue());
}else if(nd.getNodeName().compareTo("schemaVersion") == 0) {
RegionOptions.schemaVersion = Integer.parseInt(nd.getNodeValue());
} else {
System.out.println("Unknown Tag:" + layout+":"+ nd.getNodeName()+"::"+nd.getNodeValue());
}
}//return(RegionOptions.l, RegionOptions.bgcolor, RegionOptions.duration);
}
}
}
}
constructor class
I need my height, top, width etc...values
package com.example.xmlparsing;
import android.content.Context;
public class Region {
int height;
int width;
int top;
int left;
String id;
int userId;
String bgcolor;
int schemaVersion;
String type;
int duration;
int lkid;
public Region(Context ApplicationContext) {
//bgcolor= new String();
// this.height= height;
}
public void updateValues(int left) {
// TODO Auto-generated method stub
this.left=left;
//top=top;
System.out.println("value_left"+left);
}
}

You have to set up your constructor like this:
public Region(Context context, int height, int width){
this.mContext = context:
this.height = height;
this.width = width;
}
