How to send data sent by BLE Device in a fragment to a new activity for display and plotting graph in app?

I am completely new to Android and just learned Object-oriented programming. My project requires me to build something on open-source code. I am really struggling with this special case. Two fragments are under activity_main, one of them is TerminalFragment. I added a menuItem (R.id.plot) in it and set if the user clicks this Item that will lead him from TerminalFragment to activity_main2. Due to receive(byte data) and TerminalFragment still on active, the data is still printing out by receiveText.append(TextUtil.toCaretString(msg, newline.length() != 0)); in activity_main.
Now, I want to convert the data to String and send it to activity_main2 for display in recyclerview and plotting graph. I am trying to use putextra and getextra but not sure how to access data from getextra in activity_main2. In my testing, the recyclerview just showed "John". Is something missing in my method? Does anyone have a better idea? Much Appreciated.

I realized I also need to add getText() in receive(). However, the recycler view won't update itself, it just captures what it has in the recyclerview of activity_main with TerminalFragment when the user click the menuItem (id,plot). Either getextrastring() or using bundle able to pass the data to Mainactivity2.
I think I need to add something else to keep adding data to the recyclerview of activity_main2 from activity_main.

How to Show Different Strings With The Same Position When Clicking Random Button?

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",

"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);

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.

Why android ViewPager OnTouchListener not called at all

Why my ViewPager OnTouchListener doesn't fire at all !!
Here is my code below:
I'm using ViewPager to automatically slide photos but when i tap on the ViewPager I need to stop the auto sliding but the problem is that my OnTouchListener doesn't fire at all.

Sorry for being not formatted. I'm new here

I found what was causing the 'ViewPager' not to fire 'OnTouchListener'
In layout XML file :
<com.techzone.yallaassouk.ExtendedViewPager
android:id="#+id/man_view_pager"
android:layout_width="fill_parent"
android:layout_height="137dp" />
<com.techzone.yallaassouk.Utils.CirclePageIndicator
android:id="#+id/indicator"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingTop="130dp"/>
the problem was the 'paddingTop' of the 'CirclePageIndicator' it was set to '130dp' which covers the 'ViewPager' and it was receiving the touch events instead of 'ViewPager' itself.
Thank you.
