package com.example.myapplication;

 

import androidx.annotation.NonNull;

import androidx.appcompat.app.AppCompatActivity;

 

import android.os.Bundle; import android.view.Menu;

import android.view.MenuInflate; import android.view.MenuItem; import android.widget.TextView;

return true;

}

@Override

public boolean onOptionsItemSelected(@NonNull MenuItem item) { switch (item.getItemId()) {

case R.id.fyit: mn.setText("FYIT"); return true;

case R.id.syit: mn.setText("SYIT"); return true;

case R.id.tyit: mn.setText("TYIT"); return true;
