    </RelativeLayout>

</FrameLayout>

<fragment
    android:id="@+id/navigation_drawer"
    android:name="com.LiderBilgisayarYazilim.cepmap.NavigationDrawerFragment"
    android:layout_width="@dimen/navigation_drawer_width"
    android:layout_height="match_parent"
    android:layout_gravity="end"
    tools:layout="@layout/fragment_navigation_drawer" />

    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:choiceMode="singleChoice"
    android:divider="@color/abc_search_url_text_selected"
    android:dividerHeight="1dp"       
    android:listSelector="@drawable/item_secici"
    android:background="@color/black_overlay"/>

和我的java文件

if ((Calendar.getInstance().getTime().after(asd.getTime())) | IkinciLisansKontrol()) {
    if (haritam.getUrl().contains("http"))
        return;
    haritam.loadUrl(getString(R.string.javascript) + getString(R.string.SJlisans1));
                        
    getSupportActionBar().setTitle(R.string.SMLisansSuresi);
    actionBaslik.setText(R.string.SMLisansSuresi);
    BenimActionbar();
    ((Button) findViewById(R.id.btnAlan)).setVisibility(View.GONE);
    ((Button) findViewById(R.id.btnCizgi)).setVisibility(View.GONE);
    ((Button) findViewById(R.id.btnDuzenle)).setVisibility(View.GONE);
    ((Button) findViewById(R.id.btnKaydir)).setVisibility(View.GONE);
    ((Button) findViewById(R.id.btnNavigator)).setVisibility(View.GONE);
    ((Button) findViewById(R.id.btnNokta)).setVisibility(View.GONE);
    ((Button) findViewById(R.id.btnSec)).setVisibility(View.GONE);
    haritam.setWebViewClient(new WebViewClient());
} else
    haritam.loadUrl(getString(R.string.javascript) + getString(R.string.SJlisans));
                    

我想使用可见菜单。

尽管我平均一周查看了互联网上的所有资源和示例，但我仍然没有找到解决方案。

我不知道为什么这个函数出错我认为问题出在这里我使用的是 android Studio 4.0.1 如果有人解决了这个问题我很高兴
