Need Help with Referencing Dynamically Created Inputs

I am trying to create a program which a user can create two matrices and then perform a certain operation on Matrix A and B which results in Matrix C.

I have been successfully able to produce code that allows the user to determine the the size of Matrix A and B, and my code is also able to go ahead and create the edit texts for these Matrices.

My problem is that for some reason I cannot reference the Edit Texts that are dynamically created to perform the operation IE (A+B=C) and have Matrix C have the correct values inserted into the Edit Texts. If anyone could help me I would GREATLY appreciate it, My code is below.

Code:
package zach.etier.osu.MC;

import android.app.Activity;
import android.content.DialogInterface;
import android.os.Bundle;
import android.view.Gravity;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup.LayoutParams;
import android.widget.Button;
import android.widget.EditText;
import android.widget.LinearLayout;
import android.widget.TableLayout;
import android.widget.TableRow;


public class  Matrix  extends Activity implements OnClickListener  {
LinearLayout A,B,C,Container;
String gotBread,gotBread2,gotBread3,gotBread4;
int Arow,Acol,Brow,Bcol;
Button infocalc;
TableRow rowA,rowB;
String[]  myTextViewsA, myTextViewsB;   

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.home);
    infocalc=(Button)findViewById(R.id.calc);
    infocalc.setOnClickListener(this);
    A=(LinearLayout)findViewById(R.id.arrayA);
    B=(LinearLayout)findViewById(R.id.arrayB);
    C=(LinearLayout)findViewById(R.id.arrayC);
    Container=(LinearLayout)findViewById(R.id.Container);
    Container.setVisibility(View.INVISIBLE);
    Bundle gotBasket =getIntent().getExtras();
    gotBread=gotBasket.getString("key");
    Arow=Integer.parseInt(gotBread);
    gotBread2=gotBasket.getString("key2");
    Acol=Integer.parseInt(gotBread2);
    gotBread3=gotBasket.getString("key3");
    Brow=Integer.parseInt(gotBread3);
    gotBread4=gotBasket.getString("key4");
    Bcol=Integer.parseInt(gotBread4);

    final EditText[] myTextViewsA = new EditText[Arow];
    for (int i = 0; i < Arow; i++) {
        TableRow rowA = new TableRow(this);
        rowA.setId(i);
        for (int j = 0; j < Acol; j++) {
            EditText cell = new EditText(this);
            cell.setHint("(" + i + ", " + j + ")");
            rowA.addView(cell);
            myTextViewsA[j] = cell;
        }
        A.addView(rowA, new TableLayout.LayoutParams(
                LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT));
                rowA.setGravity(Gravity.CENTER);
    }

    final EditText[] myTextViewsB = new EditText[Brow];
    for (int i = 0; i < Brow; i++) {
        TableRow rowB = new TableRow(this); 
        rowB.setId(i);
        for (int j = 0; j < Bcol; j++) {
            EditText cell = new EditText(this);
            cell.setHint("(" + i + ", " + j + ")");
            rowB.addView(cell);
            myTextViewsB[i] = cell;
        }
        B.addView(rowB, new TableLayout.LayoutParams(
                LayoutParams.FILL_PARENT,
                LayoutParams.WRAP_CONTENT));
                rowB.setGravity(Gravity.CENTER);
    }
    Container.setVisibility(View.VISIBLE);

}
    public void onClick(View v) {
        // TODO Auto-generated method stub  
        final EditText[] myTextViewsC = new EditText[Arow];
        for (int i = 0; i < Arow; i++) {
            TableRow rowC = new TableRow(this);      
            for (int j = 0; j < Acol; j++) {
                EditText cell = new EditText(this);
                cell.setText("(" + i + ", " + j + ")");
                rowC.addView(cell);
            }
            C.addView(rowC, new TableLayout.LayoutParams(
                    LayoutParams.FILL_PARENT,
                    LayoutParams.WRAP_CONTENT));
                    rowC.setGravity(Gravity.CENTER);
    }
}
}
