DecimalFormat java allow to type 0 after dot

I have a DecimalFormat with the following pattern "#,###.###"
But when I want to type for example 50.05 it does not allow to, as I parse the string to number every time a text changes and when I call
df.parse("50.0");
it returns 50. and cuts the 0
Any ideas what can I do to be able to type numbers like 50.05 ?
The full code of my class is presented below. Sorry if it is too verbose:
private class NumberTextWatcher implements TextWatcher {
#SuppressWarnings("unused")
private static final String TAG = "NumberTextWatcher";
private DecimalFormat df;
private DecimalFormat dfnd;
private boolean hasFractionalPart;
private EditText et;
NumberTextWatcher(EditText et) {
df = (DecimalFormat) DecimalFormat.getInstance(Locale.ENGLISH);
df.applyLocalizedPattern(hasThousandSeparator ? "#,###.###" : "####.###");
df.setDecimalSeparatorAlwaysShown(true);
df.setMaximumFractionDigits(maxDecimal);
dfnd = (DecimalFormat) DecimalFormat.getInstance(Locale.ENGLISH);
dfnd.applyLocalizedPattern(hasThousandSeparator ? "#,###" : "####");
dfnd.setMaximumFractionDigits(maxDecimal);
this.et = et;
hasFractionalPart = false;
}
#Override
public void afterTextChanged(Editable s) {
et.removeTextChangedListener(this);
try {
int inilen, endlen;
inilen = et.getText().length();
String sign = hasSign ? s.toString().startsWith("-") ? "-" : "+" : null;
String sStr = hasSignAttached(s) ? s.toString().substring(1) : s.toString();
String v = sStr.replace(String.valueOf(df.getDecimalFormatSymbols().getGroupingSeparator()), "");
if(v.length() == 0){
return;
}
if(hasFractionalPart){
String[] vSplit = v.split("\\.");
String intStr = vSplit[0];
String decStr = vSplit.length > 1 ? vSplit[1] : "";
if(intStr.length() > maxNumbers)
intStr = intStr.substring(0, maxNumbers);
if(decStr.length() > maxDecimal)
decStr = decStr.substring(0, maxDecimal);
v = String.format("%s.%s", intStr, decStr);
} else {
if(v.length() > maxNumbers)
v = v.substring(0, maxNumbers);
}
Number n = df.parse(v);
int cp = et.getSelectionStart();
String formatted;
if (hasFractionalPart) {
formatted = df.format(n);
} else {
formatted = dfnd.format(n);
}
et.setText(hasSign ? String.format("%s%s", sign, formatted) : formatted);
endlen = et.getText().length();
int sel = (cp + (endlen - inilen));
if (sel > 0 && sel <= et.getText().length()) {
et.setSelection(sel);
} else {
// place cursor at the end?
et.setSelection(et.getText().length() - 1);
}
} catch (Exception e) {
ExceptionTracker.trackException(e);
} finally {
et.addTextChangedListener(this);
}
}
private boolean hasSignAttached(Editable s){
return s.toString().startsWith("+") || s.toString().startsWith("-");
}
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
if(hasSign && start == 1 && count == 1){
et.setText("");
}
}
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
hasFractionalPart = s.toString().contains(String.valueOf(df.getDecimalFormatSymbols().getDecimalSeparator()));
}
}

this code solves the problem:
import java.text.DecimalFormat;
public class DecimalFormatExample {
public static void main(String[] args) {
DecimalFormat dformat = new DecimalFormat("#,###.###");
dformat.setMinimumFractionDigits(1);
String someNumber = "50.05";
Double someNumberDouble = Double.valueOf(someNumber);
System.out.println(dformat.format(someNumberDouble)); // 50.05
someNumber = "50.0";
someNumberDouble = Double.valueOf(someNumber);
System.out.println(dformat.format(someNumberDouble)); // 50.0
}
}

Ok, I have done a small hack to fix this. May be it will help someone in the future, or someone will suggest a better solution.
So I added the following checks:
boolean decHasZeroAtEnd = false;
.......
if(decStr.endsWith("0")){
decHasZeroAtEnd = true;
}
.......
if(decHasZeroAtEnd){
decHasZeroAtEnd = false;
formatted = String.format("%s0", formatted);
}
And the whole code is the following:
private class NumberTextWatcher implements TextWatcher {
#SuppressWarnings("unused")
private static final String TAG = "NumberTextWatcher";
private DecimalFormat df;
private DecimalFormat dfnd;
private boolean hasFractionalPart;
private EditText et;
NumberTextWatcher(EditText et) {
df = (DecimalFormat) DecimalFormat.getInstance(Locale.ENGLISH);
df.applyLocalizedPattern(hasThousandSeparator ? "#,###.###" : "####.###");
df.setDecimalSeparatorAlwaysShown(true);
df.setMaximumFractionDigits(maxDecimal);
dfnd = (DecimalFormat) DecimalFormat.getInstance(Locale.ENGLISH);
dfnd.applyLocalizedPattern(hasThousandSeparator ? "#,###" : "####");
dfnd.setMaximumFractionDigits(maxDecimal);
this.et = et;
hasFractionalPart = false;
}
#Override
public void afterTextChanged(Editable s) {
et.removeTextChangedListener(this);
try {
int inilen, endlen;
inilen = et.getText().length();
String sign = hasSign ? s.toString().startsWith("-") ? "-" : "+" : null;
String sStr = hasSignAttached(s) ? s.toString().substring(1) : s.toString();
String v = sStr.replace(String.valueOf(df.getDecimalFormatSymbols().getGroupingSeparator()), "");
if(v.length() == 0){
return;
}
boolean decHasZeroAtEnd = false;
if(hasFractionalPart){
String[] vSplit = v.split("\\.");
String intStr = vSplit[0];
String decStr = vSplit.length > 1 ? vSplit[1] : "";
if(intStr.length() > maxNumbers)
intStr = intStr.substring(0, maxNumbers);
if(decStr.length() > maxDecimal)
decStr = decStr.substring(0, maxDecimal);
if(decStr.endsWith("0")){
decHasZeroAtEnd = true;
}
v = String.format("%s.%s", intStr, decStr);
} else {
if(v.length() > maxNumbers)
v = v.substring(0, maxNumbers);
}
Number n = df.parse(v);
int cp = et.getSelectionStart();
String formatted;
if (hasFractionalPart) {
formatted = df.format(n);
} else {
formatted = dfnd.format(n);
}
if(decHasZeroAtEnd){
decHasZeroAtEnd = false;
formatted = String.format("%s0", formatted);
}
Log.d("testt", "formatted " + formatted);
et.setText(hasSign ? String.format("%s%s", sign, formatted) : formatted);
endlen = et.getText().length();

} else {

}
} catch (Exception e) {

}

This is the above code please go through it and let me know if any clarifications are required. I cannot able to set "itemsTotal" value to "noOfIttems" textview. I have added the comments. Please help me in solving this issue.

Please check your noOfItems textView's id. TextView is null.

i have downloaded a android game program from internet and i tried to run it gives error on Method and goto statement.
i know goto statement is not support in java..
i dont know they are any other tool or language .
i want to know which technology or tool or language they are used.

What you have here is not real Java, and you should not be using it as an example to learn Java programming from.
So what actually is this stuff?
It looks to me like someone has attempted to decompile an Android app, and the decompiler was unable to turn some of the code back into real Java. Instead, the decompiler has inserted goto "statements" in an attempt to convey the meaning of the code to the (human) reader.

This is obviously the output of a decompilation. While this is a good way to gain specific insight into programs, it's not beginner-level material just like #Jägermeister said, because jads lack the clarity and brevity of standard Java source code.
For example, the goto keyword is not supported on the source code side of the JDK, but it is used inside the byte code in the form of jump instructions. Breaks, continues, loops, ifs etc. may be turned into jumps in surjective ways. The decompiler cannot restore the original construct and resorts to just putting the gotos and labels in the jad. It's up to the programmer to restore reasonable, compilable flow constructs.
That said, the comprehensive answer to your question would be: it's java, but rather an image of the byte code stuff, not a strict restoration of the source code, and requires a manual touch-up to be compilable again.

How to generate 24 string values randomly on textview in android?

i would like to generate 24 string values on 24 textview which i created the xml file in android and also i code for the getid and set listener but not mentioned here.
In the override oncick method i define the click fun method.
In this code i simply code for the integer values but now i would like to compare from the string array which has static values like
String[] value = {11,12,13,14,15,16,17,18,19,20,21,22,11,12,13,14,15,16,17,18,19,20,21,22};

I don't think I understand your situation fully.
1. Create an array of String resources:
private Integer[] Strings = { many, strings, R.string.stringa };
2. Call a method to get a random resource:
getRandomString(int);
3. Return a random String:
private String getRandomString(int random)
return getString( Strings[ random ] );

change imageview using int

I've been stuck on this for a whole day, please help me. So I have 2 arrays filled with five dice rolls from two players and I want to set them to the according dice image that I put in my drawable. This is the original code that I have, displaying the arrays in TextView.
int player1[] = new int[5];
int player2[] = new int[5];
TextView p1Dice, p2Dice;
private void displayDice() {
StringBuffer sbfNumbers = new StringBuffer();
for (int i = 0; i < 5; i++) {
sbfNumbers.append(player1[i] + " ");
}
StringBuffer sbfNumbers2 = new StringBuffer();
for (int i = 0; i < 5; i++) {
sbfNumbers2.append(player2[i] + " ");
}
p1Dice.setText(sbfNumbers.toString());
p2Dice.setText(sbfNumbers2.toString());
I can't figure out how to get it to display the ImageView instead.
private final static int[] diceImages = new int[] { R.drawable.d1,
R.drawable.d2, R.drawable.d3, R.drawable.d4, R.drawable.d5, R.drawable.d6 };
ImageView p1Dice1, p1Dice2, p1Dice3, p1Dice4, p1Dice5;
for (int i = 0; i < 5; i++) {
p1Dice[i].setImageResource(diceImage[player1[i]]);
}
What I am missing?
Here's my full code, sorry its a mess. I just started to learn programming on my own and this is my first program. Any advice on making it better is appreciated too.

Thank you so much in advanced. Any help is highly appreciated. Thanks again!!

In your code imageViews are not in an array, so you cannot do p1Dice[i] .
So please change to
private ImageView[] p1Dice = new ImageView[5];
or
p1Dice1.setImageResource(diceImage[player1[0]]);
p1Dice2.setImageResource(diceImage[player1[1]]);
p1Dice3.setImageResource(diceImage[player1[2]]);

The ImageViews are not in an array, so you cannot do p1Dice[i].something()
Change the declaration to ImageViews to this
private ImageView[] p1Dice = new ImageView[5];
