Ich bekomme meine App abgestürzt, wenn ich die Methode implementieren setSupportActionBar

Question

Nun, die Sache ist, wenn ich diese setSupportActionBar (Symbolleiste) von der Aktivität add_event löschen, funktioniert es, die Aktivität add_event öffnet und alle Schaltflächen und TextEdits auf zeigen der Bildschirm, aber zeigen Sie keine Schaltfläche auf der Symbolleiste, nur die Symbolleiste, sauber, und wenn ich diese setSupportActionBar -Methode setzen, stürzt es ab, wenn ich die Aktivität aufrufen (add_event).

Kann jemand erklären, was passiert? Vielen Dank im Voraus :)

Ich habe einige Codes hier setzen, aber ihr Jungs können das gesamte Projekt in meinem GitHub herunterladen

https://github.com/dennysfarias/RemindIt

public class MainActivity extends AppCompatActivity { 

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


public void callactAddEvt(){ 
    Intent callAddEvt = new Intent(MainActivity.this, add_event.class); 
    MainActivity.this.startActivity(callAddEvt); 
} 

@Override 
public boolean onCreateOptionsMenu(Menu menu){ 
    getMenuInflater().inflate(R.menu.menu, menu); 
    return true; 
} 


//put the options inside the 3dot menu 
@Override 
public boolean onOptionsItemSelected(MenuItem item) { 
    switch (item.getItemId()) { 
     case R.id.action_settings: 
      // User chose the "Settings" item, show the app settings UI... 
      Toast.makeText(getApplicationContext(), "Settings Option Pressed", Toast.LENGTH_SHORT).show(); 
      return true; 

     case R.id.action_addevent: 
      //User chose the AddEvent action, whom calls the com.ddtec.remindit.add_event activity 
      callactAddEvt(); 
      Toast.makeText(getApplicationContext(), "Add Event Option Pressed", Toast.LENGTH_SHORT).show(); 

      return true; 
     default: 
      // If we got here, the user's action was not recognized. 
      // Invoke the superclass to handle it. 
      Toast.makeText(getApplicationContext(), "No Option Pressed", Toast.LENGTH_SHORT).show(); 

      return super.onOptionsItemSelected(item); 

    } 
} 
} 

Das ist mein MainActivity es funktioniert gut, ich versuche, das auf meinem Handy und es sieht gut aus.

Jetzt bin zeige ich werde meine zweite Tätigkeit

public class add_event extends AppCompatActivity { 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.add_event); 

    Toolbar toolbar = (Toolbar)findViewById(R.id.my_toolbar2); 
    setSupportActionBar(toolbar); 
} 


@Override 
public boolean onCreateOptionsMenu(Menu menu){ 
    getMenuInflater().inflate(R.menu.menu_add_event, menu); 
    return true; 
} 




@Override 
public boolean onOptionsItemSelected(MenuItem item) { 
    switch (item.getItemId()) { 
     case R.id.action_addfinish: 
      // User chose the Done action, saving the event... 
      Toast.makeText(getApplicationContext(), "Finish/Save Option Pressed", Toast.LENGTH_SHORT).show(); 

      return true; 

     case R.id.action_cancel: 
      // User chose the Cancel action, leaving without saving the current event... 
      Toast.makeText(getApplicationContext(), "Cancel Option Pressed", Toast.LENGTH_SHORT).show(); 

      return true; 

     case R.id.action_settings: 
      Toast.makeText(getApplicationContext(), "Settings Option Pressed", Toast.LENGTH_SHORT).show(); 

      return true; 


     default: 
      // If we got here, the user's action was not recognized. 
      // Invoke the superclass to handle it. 
      Toast.makeText(getApplicationContext(), "No Option Pressed", Toast.LENGTH_SHORT).show(); 

      return super.onOptionsItemSelected(item); 

    } 
} 
}

Answer 1

In Ihrem menu_add_event.xml auf Linie No: 13 Sie hinzugefügt haben 'android: onClick = "ClearAll"'. Dies verursacht das Problem. Entfernen Sie diese Zeile oder fügen Sie in Ihrer Aktivität die folgende Funktion hinzu.

public boolean ClearAll(MenuItem item) { 
// actions 
}
