How to show user input from dynamic created EditTexts in TextViews into another activity?

In main activity I have button which onClick method creates EditText every time when user clicks this button. I wanted to pass user input from each EditText to TextView into another activity. But TextView shows user input only from last EditText. My code may look strange, because I tried to solve problem on my own. How can I show user input from each created EditText? I am new to programming. Thank you in advance.
Java code
EditText code
int i=1;
int numberOfCreated = 2;
public void buttonCreate(View view){ // button onClick method
for(i=1;i<numberOfCreated;i++){
LinearLayout createdEditText1Layout=findViewById(R.id.createdEditText1Layout);
editText1 = new EditText(this);
LinearLayout.LayoutParams paramsForEditText1 = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
editText1.setLayoutParams(paramsForEditText1);
editText1.setInputType(InputType.TYPE_CLASS_TEXT);
editText1.setHint(R.string.editText1Hint);
editText1.setTextSize(16);
createdEditText1Layout.addView(editText1);
}
}
Intent to pass string to second activity
public void openResult() {
String productName = editText1.getText().toString();
Intent intent2 = new Intent(this, ResultActivity.class);
intent2.putExtra("product", productName);
startActivity(intent2);
}
public void buttonResultClick(View view){
openResult();
}
Second activity
int i=1;
int numberOfButtons = 2;
for(i=1;i<numberOfButtons;i++) {
LinearLayout layoutForProductName = findViewById(R.id.layoutForProductName);
TextView productNameTextView = new TextView(this);
LinearLayout.LayoutParams layoutParamsForProductNameTextView = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
productNameTextView.setLayoutParams(layoutParamsForProductNameTextView);
productNameTextView.setTextSize(40);
String productName = getIntent().getStringExtra("product");
productNameTextView.setText(productName);
layoutForProductName.addView(productNameTextView);
}

From what I can tell it's because you're adding only one String productName
You can solve this by passing a String Array aka String[]
public void openResult() {
ArrayList<String> productNames = new ArrayList<String>();
for(int y=0; y < createdEditText1Layout.getChildCount(); y++)
{
if((View)layout.getChildAt(y) instanceof TextView){
String productName = editText1.getText().toString();
productNames.add(productName);
}
}
Intent intent2 = new Intent(this, ResultActivity.class);
intent2.putStringArrayListExtra("product", productNames);
startActivity(intent2);
}
And then in the second Activity you would recalled like
int i=1;
int numberOfButtons = 2;
for(i=1;i<numberOfButtons;i++) {
LinearLayout layoutForProductName = findViewById(R.id.layoutForProductName);
TextView productNameTextView = new TextView(this);
LinearLayout.LayoutParams layoutParamsForProductNameTextView = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
productNameTextView.setLayoutParams(layoutParamsForProductNameTextView);
productNameTextView.setTextSize(40);
String productName = getIntent().getExtras().getStringArrayList("product").get(i);
productNameTextView.setText(productName);
layoutForProductName.addView(productNameTextView);
}

How to get the edittext variable: java android?

I want to get different variables for the editText which i coded with java (LOOP) not XML.
I am working on a project where user is asked how many courses did you offer?, if 10 the EditText will appear 10 times. But I want to get the variable name of each editText and its value. I am only getting the value of the last one.

Either you store it in an array,map, or setTag.
You just created the elements but has no way of accessing them again.
It depends on how you're planning to use the elements.
If you can add more detail to the question, then maybe we can set the best answer.

Make your dynamically EditText on TableLayout, then access it by its row.
Idk, sth like this maybe
String[] value = new String[YOUR-COURSE-NUMBER];
for (int i = 0; i < YOUR-COURSE-NUMBER; i++) {
TableRow tableRow = (TableRow) yourTableLayout.getChildAt(i);
EditText yourET = (EditText) tableRow.getChildAt(0);
value[i]= yourET.getText().toString();
}

Why is my variable decrementing?

while(i < numCourses){
final int index = i;
//Create a Dialog
final Dialog dialog = new Dialog(MainActivity.this);
dialog.setContentView(R.layout.input_dialog);
TextView textView = (TextView) dialog.findViewById(R.id.textView4);
textView.setText("" + i);
dialog.show();
//Button for the dialog.
Button b = (Button) dialog.findViewById(R.id.button);
b.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//Get input Course Numbers, numCourses times
EditText editText = (EditText) dialog.findViewById(R.id.editText2); //EditText
String getInput = editText.getText().toString(); //String input
try {
courseNumbers[index] = Integer.parseInt(getInput);
Toast.makeText(MainActivity.this, "" + courseNumbers[index], Toast.LENGTH_SHORT).show();
}catch (Exception ex){}
//Dismiss dialog
dialog.dismiss();
}
});
i++;
}
This is what my variable int = i shows up in the Dialog, suppose numCourses was 4:
3
2
1
0
My question is why is decrementing backwards, instead of incrementing forward from 0 to 3. And to receive an array of inputs from a dialog, how can I efficiently ask for input, numCourses times? Instead of me having a while loop and incrememnting i, which I feel is not efficient.

Not using loop, after each input has been clicked, then show the next dialog.
public void showCourseDialog(final int i, final int numCourses){
final int index = i;
//Create a Dialog
final Dialog dialog = new Dialog(MainActivity.this);
dialog.setContentView(R.layout.input_dialog);
TextView textView = (TextView) dialog.findViewById(R.id.textView4);
textView.setText("" + i);
dialog.show();
//Button for the dialog.
Button b = (Button) dialog.findViewById(R.id.button);
b.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//Get input Course Numbers, numCourses times
EditText editText = (EditText) dialog.findViewById(R.id.editText2); //EditText
String getInput = editText.getText().toString(); //String input
try {
courseNumbers[index] = Integer.parseInt(getInput);
Toast.makeText(MainActivity.this, "" + courseNumbers[index], Toast.LENGTH_SHORT).show();
}catch (Exception ex){}
//Dismiss dialog
dialog.dismiss();
if(i < numCourses)
showCourseDialog(++i, numCourses);
}
});
}

Here is my code for creating textviews dynamically.
and i am successful in this.
Now i want to add grid view or listview beneath every text view like the following image :
The same way i want to show text view and display grid or list view on click and this all should be made on bases of arry1 named array's length.
All i want is to create grid or list view dynamically.

cannot be resolved or is not a field with some EditTexts

Ok so i have the following situation : I create some Editexts dynamically and i want to add another row of Editexts when one of the EditTexts from the last row is clicked.
I tried doing it the following way :
When the last row of EditTexts is created,i assign each of them an id
et.setId(997);
et.setId(998);
et.setId(999);
I declared each of them ;
public EditText camp1;
public EditText camp2;
public EditText camp3;
camp1 = (EditText) findViewById(997);
camp2 = (EditText) findViewById(998);
camp3 = (EditText) findViewById(999);
camp1.setOnClickListener(this);
camp2.setOnClickListener(this);
camp3.setOnClickListener(this);
And when i try to do this
case R.id.camp1:
inside a switch i get "camp1 cannot be resolved or is not a field"
What am i doing wrong ?
Is there a better way to detect when the last Edittext is clicked and create a new one ?

All you care about is the last editText, right? Just give the last editText an onClickListener that creates another editText. Then give the new editText the onClickListener and remove it from the the previous "last one".
like this:
camp1 = (EditText) findViewById(997);
camp2 = (EditText) findViewById(998);
camp3 = (EditText) findViewById(999);
camp1.setOnClickListener(this);
camp2.setOnClickListener(this);
camp3.setOnClickListener(new myListener());
...
//put this private class in the same activity as the stuff above
private class myListener implements View.OnClickListener {
#Override
public void onClick(View view) {
EditText editText = new EditText(YourActivityName.this);
editText.setOnClickListener(new myListener());
//TODO put it in your viewGroup
//Give the old EditText your standard onClickListener
view.setOnClickListener(YourActivityName.this);
//To change body of implemented methods use File | Settings | File Templates.
}
}

setId() does not add any variables to the R.id class because setId() executes at run-time, but R is generated at compile-time. Since you are creating dynamic views, you need to rethink your onClick() method. You might want to consider using a ListView to help you. You can also set up the three TextViews using a separate XML file, such as row.xml.
