Bonsoir à toutes et à tous.

Etant débutant dans le dev mobile je me tourne vers vous car je ne vois pas comment régler mon problème. Je dispose de deux activity dans mon projet sur android studio. J'ai la MainActivity et InscriptionActivity. Or lorsque je fais un Toast en cliquant sur un des boutons de la mainActivity je n'ai pas de soucis, le toast s'affiche bien à l'écran, mais lorsque je fais des Toast depuis InscriptionActivity rien ne se passe. De plus, J'ai constaté le même problème avec l'utilisation du LogCat, pas de soucis sur la MainActivity mais dès que je passe à une autre activity que la main et bien le logcat et les boutons ne réagissent plus.

Pouvez-vous m'aider s'il vous plait ?

MainActivity.java

package com.example.simplesporttrainerv2;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;

public class MainActivity extends AppCompatActivity {


@Override
protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

Button buttonConnexion = (Button) findViewById(R.id.button_connexion);
Button buttonInscription = (Button) findViewById(R.id.button_inscription);
Button buttonInscription2 = (Button) findViewById(R.id.button_inscription2);

buttonConnexion.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {

                Toast.makeText(MainActivity.this, "Vous avez cliqué sur le bouton connexion", Toast.LENGTH_SHORT).show();
setContentView(R.layout.activity_main);

}
        });

buttonInscription.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {

                Toast.makeText(MainActivity.this, "Vous avez cliqué sur le bouton inscription", Toast.LENGTH_SHORT).show();
