Main activity.java :-

package com.example.callrepeat;
import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.os.Handler;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {

   EditText etnumber;
   Handler mhandler = new Handler();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        etnumber = findViewById(R.id.et);

    }


    public void repeat(View view) {
        mhandler.postDelayed(mtoastrunnable, 5000);
    }

    public void stoprepeat(View view) {
        mhandler.removeCallbacks(mtoastrunnable);
        Toast.makeText(this, "call has stopped", Toast.LENGTH_SHORT).show();
    }

    private Runnable mtoastrunnable = new Runnable() {
        @Override
        public void run() {
   String phone = etnumber.getText().toString();
   if (phone.isEmpty()) {
   Toast.makeText(MainActivity.this, "Please enter mobile number", Toast.LENGTH_SHORT).show();
            } else {
       String s = "tel:" + phone;
       Intent intent = new Intent(Intent.ACTION_CALL);
       intent.setData(Uri.parse(s));
       startActivity(intent);
       Toast.makeText(MainActivity.this, "Call attack is going", Toast.LENGTH_SHORT).show();
       mhandler.postDelayed(mtoastrunnable, 5000);
            }
        }
    };
}
