Error:(106, 20) error: method onCreate(Bundle) is already defined in class MainActivity

Question

我在从另一个项目添加 Google AdMob 代码时遇到问题，因为我的部分代码似乎也使用了 onCreate(Bundle)。

这是我项目中使用 MainActivity.java 中的 onCreate(Bundle) 的部分：

      @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);



    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
            this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
    drawer.addDrawerListener(toggle);
    toggle.syncState();

    NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
    navigationView.setNavigationItemSelectedListener(this);
}

我要添加的部分：

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

    // Load an ad into the AdMob banner view.
    AdView adView = (AdView) findViewById(R.id.adView);
    AdRequest adRequest = new AdRequest.Builder()
            .setRequestAgent("android_studio:ad_template").build();
    adView.loadAd(adRequest);

    // Toasts the test ad message on the screen. Remove this after defining your own ad unit ID.
    Toast.makeText(this, TOAST_TEXT, Toast.LENGTH_LONG).show();
}

我是 java 的新手，如有任何帮助，我们将不胜感激。

谢谢。

The part I'm trying to add

您应该将此部分添加到现有 onCreate 方法中，而不是整个方法主体

// Load an ad into the AdMob banner view.
AdView adView = (AdView) findViewById(R.id.adView);
AdRequest adRequest = new AdRequest.Builder()
        .setRequestAgent("android_studio:ad_template").build();
adView.loadAd(adRequest);

// Toasts the test ad message on the screen. Remove this after defining your own ad unit ID.
Toast.makeText(this, TOAST_TEXT, Toast.LENGTH_LONG).show();
