工具栏菜单导致我的应用程序在打开时崩溃

Toolbar menu causes my application to crash when opened

我在使用工具栏中的菜单时遇到问题。该项目已构建,但是当按下右上角的下拉菜单时,应用程序崩溃了。起初我以为菜单本身膨胀可能是个问题,但我找不到导致此错误的行。

MainActivity.java:

public class MainActivity extends AppCompatActivity {
    CircleImageView usrImg;
    TextView usrName;

    FirebaseUser firebaseUser;
    DatabaseReference ref;

    @RequiresApi(api = Build.VERSION_CODES.KITKAT)
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        //<-------TOOLBAR LAYOUT----------->
        Toolbar toolbar = findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        getSupportActionBar().setTitle("");
    }

    //MENU CONTROLS
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.menu, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(@NonNull MenuItem item) {
        switch (item.getItemId()){
            case R.id.signOut:
                FirebaseAuth.getInstance().signOut();
                startActivity(new Intent(MainActivity.this,LoginActivity.class));
                finish();
                return true;
        }
        return false;
    }
}

尝试更改下面给出的代码行。提供任何自定义主题或任何其他主题,如果您不想要任何主题,您也可以删除 popupTheme 它将正常工作

 app:popupTheme="@style/TextAppearance.AppCompat.Widget.ActionBar.Menu"
