setonlongclicklistener for several buttons at once

Question

I want that button1,2,3 respond to a longclick, the user will be prompt to enter the text's button. Inside of onCreate I wrote:

Button botonEditable;
Context context;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    ...
    context = MainActivity.this;
    Resources r = getResources();
    String pName = getPackageName();

    for (int i=1;i<4;i++){
    botonEditable = (Button) findViewById(r.getIdentifier("button" + i, "id", pName));
    botonEditable.setOnLongClickListener(new View.OnLongClickListener() {
        public boolean onLongClick(View v) {
            final AlertDialog.Builder alert = new AlertDialog.Builder(context);
            alert.setMessage("Nueva Categoria:");
            final EditText input = new EditText(context);
            alert.setView(input);
            alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int whichButton  ) {
                    // Do something with value!
                    String newCateg = input.getText().toString();
                    botonEditable.setText(newCateg);
                }
            });

            alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int whichButton) {
                    // Canceled.
                }
            });        
            alert.show();                   
            return true;
        }
    });
    }
 }

When this is tested, the 3 buttons responds accordingly to show an alert message, but when I enter text and click ok, the text is changed only in button3, no matter which button has been longclicked :( What It's wrong and how fix it in a simple way?

Answer 1

I found the solution, in my code I just replaced the line

public boolean onLongClick(View v) {....

by this one

public boolean onLongClick(final View v) {....

plus your suggestions:

((Button)v).setText(newCateg.toUpperCase());

Now, everything is alright. Thankyou guys, your help left me at millimeters of the solution.
