The XML file contains a radio group and few radio buttons, when i try to run the code without any sort of radio buttons and comment out the code, works perfectly
Make sure all your RadioButtons and RadioGroup have different id's in the layout file.
Another small optimization would be to look for the RadioButtons inside RadioGroup as following.
RadioButton selected = (RadioButton) allOptions.findViewById(
allOptions.getCheckedRadioButtonId());

How to Show Different Strings With The Same Position When Clicking Random Button, So when the string is randomized the word and word2 display the same position data and in different textview. I have been looking for information for a few days and have not found an answer yet. I am confused to do so can you help me? Here's the Java file I have.
Adapter.java
package com.word.game;
import java.util.Random;
public class Adapter {
public static final Random RANDOM = new Random();
public static final String[] WORDS = {"RUN",
"WALK",
"CRY",
"SUGAR",
"SALT",
"RAIN",
"NOVEMBER"};
public static final String[] WORDS2 = {"FAST",
"RELAX",
"TEARS",
"DRINK",
"RECIPERS",
"WATER",
"CALENDAR"};
public static String randomWord2() {
return WORDS2[RANDOM.nextInt(WORDS2.length)];
}
public static String randomWord() {
return WORDS[RANDOM.nextInt(WORDS.length)];
}
public static String shuffleWord(String word) {
if (word != null && !"".equals(word)) {
char a[] = word.toCharArray();
for (int i = 0; i < a.length; i++) {
int j = RANDOM.nextInt(a.length);
char tmp = a[i];
a[i] = a[j];
a[j] = tmp;
}
return new String(a);
}
return word;
}
}

If you want to return same position in different arrays with same size,
Try this
public static String randomWord2(int pos) {
return WORDS2[pos];
}
public static String randomWord(int pos) {
return WORDS[pos];
}
public static int randomNum() {
return RANDOM.nextInt(WORDS.length);
}
When You are invoking randomWord() and randomWord2() , get the random position first and the pass it to the methods
int pos= randomNum();
word1=randomWord(pos);
word2=randomWord2(pos);
I updated the table in sqlite database,
but i don't know how to get the updated details
in the same activity with refresh when pressing update a buttton.
i tried below code
finish();
startActivity(getintent());
It loading the same Activity again and showing nothing .
I know this is not the right way.I need your help.
Thanks in advance.
this is my code.

Why you calling startActivity Again & again ?
Good Approach
Use notifyDataSetChanged()
Notifies the attached observers that the underlying data has been
changed and any View reflecting the data set should refresh itself.
ad.notifyDataSetChanged();
Code
dbup = openOrCreateDatabase("monthapp", MODE_PRIVATE, null);
dbup.execSQL("UPDATE monthvaluesOrgin SET currentpaid='" + add + "' WHERE id='" + id + "'");
Toast.makeText(getApplicationContext(), "added" + add + "\n" + id, Toast.LENGTH_LONG).show();
ad.notifyDataSetChanged(); // This
create method to update list in Adapter, and after updating DB call it
public void refresh(Cursor newCursor) {
if (mCursor != null) mCursor.close();
mCursor = newCursor;
if (newCursor != null)
this.notifyDataSetChanged();
}

Your issue actually brings up a larger issue that is especially relevant when developing a mobile app: Locale. Rather than use Double.parse(), which does not take Locale into account, consider using NumberFormat instead.
NumberFormat nf = NumberFormat.getInstance(); //gets an instance with the default Locale
Number parsed = nf.parse(percentageView.getText().toString());
beanEachQuetionScore.quetionScore = parsed.doubleValue();
For your float values, you can use the same concept:
Number parsedFloat = nf.parse(someFloatString);
float floatVal = parsedFloat.floatValue();
This of course assumes that OP is in a Locale that uses ',' instead of '.' as a separator.

Not sure what I am doing wrong, I tried various things and trying to look up different ways to go about doing this and none of them have worked... maybe it is something more simple than I see... the problem I think lies in the private class within this class.
I haven't read your code in great detail, but I suspect a strong contributor is this:
HttpPost httppost = new HttpPost("http://127.0.0.1:3000/wardrobe");
If you're using the emulator it's probably more likely you want to connect to "10.0.2.2". which is:
Special alias to your host loopback interface (i.e., 127.0.0.1 on your
development machine)
See here for more details on the emulator networking:

I populate an alerttdialog from a database. I store these values in an arrayList, convert them to an charsequence list then set them to my alertdialog builder. As shown:
This is a screenshot of my populated 'text template' options from my database:
At the moment when I click one of my options for example Call me. it displays as it should within a specified edittext. If I click on one of the other options such as 'Email me' this is ignored, only my first 'if' option Call me. will work as shown:
This leads me to believe for some reason only Call me has been added to my charsequence array but I'm not sure why. Here is my complete class. I am getting this issue at the longOnClick method. I have marked this issue area on the code below:

Slightly embarrassing but I've just realized I have different strings comparing my IFs to the strings stored in the charsequence, so it is now working!
