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.

converting numbers to currency format when text changes

I am using RxTextView.textChanges for EditText that when the user is typing change value of EditText to convert numbers to currency format like below:
1,000
But I can't see any convert numbers to currency format.
I am using from: NumberFormat.getNumberInstance(Locale.US).format(productPrice);
My code is like bellow:
Observable<CharSequence> observableDiscountPrice = RxTextView.textChanges(discountPriceEdittext);
observableDiscountPrice.map(new Function<CharSequence, Boolean>() {
#Override
public Boolean apply(#io.reactivex.annotations.NonNull CharSequence charSequence) throws Exception {
try {
if (charSequence.length() > 0) {
String pPrice = NumberFormat.getNumberInstance(Locale.US).format(charSequence.toString());
originalPriceEdittext.setText(String.valueOf(pPrice));
return true;
} else {
return false;
}
} catch (Exception e) {
return true;
}
}
}).subscribe(new Subject<Boolean>() {
#Override
public boolean hasObservers() {
return false;
}
#Override
public boolean hasThrowable() {
return false;
}
#Override
public boolean hasComplete() {
return false;
}
#Override
public Throwable getThrowable() {
return null;
}
#Override
protected void subscribeActual(Observer<? super Boolean> observer) {
}
#Override
public void onSubscribe(#io.reactivex.annotations.NonNull Disposable d) {
}
#Override
public void onNext(#io.reactivex.annotations.NonNull Boolean aBoolean) {
}
#Override
public void onError(#io.reactivex.annotations.NonNull Throwable e) {
}
#Override
public void onComplete() {
}
});

Use this TextWatcher class:
public class NumberTextWatcherWithSeperator implements TextWatcher {
private EditText editText;
public NumberTextWatcherWithSeperator(EditText editText) {
this.editText = editText;
}
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
#Override
public void afterTextChanged(Editable s) {
try {
editText.removeTextChangedListener(this);
String value = editText.getText().toString();
if (!value.equals("")) {
if (value.startsWith(".")) {
editText.setText("0.");
}
if (value.startsWith("0") && !value.startsWith("0.")) {
editText.setText("");
}
String str = editText.getText().toString().replaceAll(",", "");
if (!value.equals(""))
editText.setText(getDecimalFormattedString(str));
editText.setSelection(editText.getText().toString().length());
}
editText.addTextChangedListener(this);
} catch (Exception ex) {
ex.printStackTrace();
editText.addTextChangedListener(this);
}
}
private static String getDecimalFormattedString(String value) {
StringTokenizer lst = new StringTokenizer(value, ".");
String str1 = value;
String str2 = "";
if (lst.countTokens() > 1) {
str1 = lst.nextToken();
str2 = lst.nextToken();
}
String str3 = "";
int i = 0;
int j = -1 + str1.length();
if (str1.charAt(-1 + str1.length()) == '.') {
j--;
str3 = ".";
}
for (int k = j; ; k--) {
if (k < 0) {
if (str2.length() > 0)
str3 = str3 + "." + str2;
return str3;
}
if (i == 3) {
str3 = "," + str3;
i = 0;
}
str3 = str1.charAt(k) + str3;
i++;
}
}
}
and
yourEditText.addTextChangedListener(new NumberTextWatcherWithSeperator(yourEditText));

Take a look at https://docs.oracle.com/javase/tutorial/i18n/format/decimalFormat.html
DecimalFormat myFormatter = new DecimalFormat("###,###.###");
String output = myFormatter.format(156456.673);
System.out.println(156456.673 + " " + "###,###.###" + " " + output);
// I/System.out: 156456.673 ###,###.### 156,456.673

In case you want to and a dollar sign
fun multiply_two_numbers() {
val x = etValOne.text.toString()
val y = etValTwo.text.toString()
val c = x.toDouble().times(y.toDouble())
//val c = (x.toDouble() * y.toDouble())
val df = DecimalFormat("$ "+"0.00")
df.roundingMode = RoundingMode.CEILING
df.format(c)
etANS.setText(df.format(c))
}

Justify text inside Android Textview

I want to Justify text inside Android TextView. With copy and share function and can accept spannable string. Can someone help me. It's so important for me. Thank you in advance

I have a solution for the text-justify in Android.
I have created a Custom Textview class, with this you can solve the justification issue in Android.
<com.trailcreator.util.JustifyCustomTextView

Here is the class

I want to pop up a drop down list on press of #.

I google'd while and i get the solution. I do code as below and its work for me.I just setup the auto-complete in our Activity onCreate() method.
In my case, i am using the # character to identify the start of pieces of text that should be lookedup and spaces to determine the end of the look up token.

Change password mask character to asterisk (*), BUT WITH DELAY

Change password mask character to asterisk (*), is not difficult, I saw this post. Change EditText password mask character to asterisk (*)
BUT, what I need is, when input the password, for example, input 'a', it will show 'a' at the EditText for one second(default is 1500ms I think). then show the '*'. I need this delay. I can not find any solution. Any help? I check the android source code, it use many internal variable, I can not override it.
