Creating TextView for dynamically created EditText using Layout Inflater Method

I'm self-taught and have fallen in love. This is my first android app which in theory is fairly simple.
The issue: I've been successful in dynamically creating new EditTexts with a click of a button using a layoutinflator method. My problem is being able to identify the new id's of those EditTexts, or simply retrieving the new input values from the new EditTexts that the user has created... so I can display them to their respective TextViews.
Thank you in advance. I sincerely appreciate it.
MainActivity.java code:
public class MainActivity extends AppCompatActivity {
LinearLayout parentLinearLayout;
Button button;
TextView result;
EditText editName;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
parentLinearLayout = findViewById(R.id.parent_linear_layout);
editName = findViewById(R.id.editName);
result = findViewById(R.id.textViewName);
button = findViewById(R.id.addName);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String name = editName.getText().toString();
result.setText(name);
}
});
}
public void onAddField(View v) {
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
final View rowView = inflater.inflate(R.layout.activity_row, null);
parentLinearLayout.addView(rowView, parentLinearLayout.getChildCount() - 1);
}
public void onDelete(View v) {
parentLinearLayout.removeView((View) v.getParent());
}

Try to get EditText and TextView from your inflated view and add TextChangedListener on EditText and update TextView inside onTextChanged
public void onAddField(View v) {
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
final View rowView = inflater.inflate(R.layout.activity_row, null);
EditText editText = rowView.findViewById(R.id.number_edit_text);
TextView textView = rowView.findViewById(R.id.your_text_view);
editText.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
textView.setText(s);
}
#Override
public void afterTextChanged(Editable s) {
}
});
parentLinearLayout.addView(rowView, parentLinearLayout.getChildCount() - 1);
}

Getting the progress of multiple seekbars in recycler view

So I am displaying a recylerview with an Image and the name of a person. Below that is a seekbar, which the user can move to rate that person.
Now I want to store the ratings (=progress) of each seekbar in a list. However right now it only stores the rating of the last seekbar in the list.
So it stores only the progress of the last seekbar right now. I would like that when the user clicks the button that every current rating value of every seekbar is stored in a list.
Thank you very much.
That is is my layout_listitem:

You can do it in multiple ways:
1- You can store seekbars value as a property in your model and update that property on OnSeekBarChangeListener and when the user hits the button get the data source from the adapter and then run a loop on it and call getter of that attribute.
2- You can store seekbars value as a List<> in your adapter and whenever the user hits the button get the list from the adapter.

How do I identify buttons right inside Java Activity Class?

I designed two buttons b1,b2 inside "KeyboardService.java" which should update the value of PACK_LIB inside "Stickers.java".
Three files attached:
main_board_layout.xml
Stickers.java
KeyboardService.java
I assigned both buttons with IDs of Button1 = b1 and Button2 = b2.
The built is successful but when I click on the buttons both do not work.
I think it is maybe a problem with this line ->
final Button button1 = (Button) mainBoard.findViewById(R.id.b1);
Because the Buttons are inside a FrameLayout. But when I use ID of that it won't work either.
Any ideas?

View Flipper that uses Only One ImageView

I'm new to Android, and am currently using a ViewFlipper. I'd like to know if it's possible to use only one ImageView? That way I can just create an Arraylist of my images. I think using multiple ImageViews is not a good practice since I have 50+ images.
public void initContent() {
imageArrayList = new ArrayList<Integer>();
imageArrayList.add(R.drawable.pig2);
imageArrayList.add(R.drawable.pig3);
imageArrayList.add(R.drawable.pig4);
imageArrayList.add(R.drawable.pig5);
imageArrayList.add(R.drawable.pig6);
imageArrayList.add(R.drawable.pig7);
imageArrayList.add(R.drawable.pig8);
imageArrayList.add(R.drawable.pig9);
imageArrayList.add(R.drawable.pig10);
imageArrayList.add(R.drawable.pig11);
imageArrayList.add(R.drawable.pig12);
imageArrayList.add(R.drawable.pig13);
imageArrayList.add(R.drawable.pig14);
imageArrayList.add(R.drawable.pig24);
imageArrayList.add(R.drawable.pig25);
imageArrayList.add(R.drawable.theend);

public class MainActivity extends Activity {
ViewFlipper viewFlipper;

Yes. Use the frame animation, delete your arraylist. Here is some sample code: Link

handling too many requests of animation on the main ui thread from other threads - android

I am working on creating activity that has too many animations, and when starting this activity the logcat shows me this message again and again during the life time of this activity:
I/Choreographer﹕ Skipped 36 frames! The application may be doing too much work on its main thread.
so I did many stuff in another threads, but still there is heavy access on the main UI thread. as well as, the animation is becoming really slow on some high resolution devices
what can be possible solution for handling this problem ?
UPDATED: added code
so here is the code of showing the views(which are 6 imageButtons),
private void setupAnimationForAllViews(ArrayList<View> listOfViews,
int animationId,
final boolean isAppearing) {
int startDelay = mDelay; // milliseconds
int numberOfViews = listOfViews.size();
for (int i = 0; i < numberOfViews; i++) {
final Animation animator = AnimationUtils.loadAnimation(mContext, animationId);
animator.setStartOffset(startDelay);
startDelay += mOffSet; // every view will start after 100 milliseconds from the other
final View currentView = listOfViews.get(i);
final int indexOfCurrentCheckedItem = i;
mMainUIThreadHandler.post(new Runnable() {
#Override
public void run() {
currentView.startAnimation(animator);
}
});
}
}
I trigger it in seperated thread like this:
new Thread(new Runnable() {
#Override
public void run() {
setupAnimationForAllViews(tempListOfViews,
animationId, isAppearing);
}
}).start();
