Öffnen Sie das Menü der Navigationsleiste in einer anderen Aktivität.

Question

Ich habe das Menü der Navigationsleiste erstellt und möchte jetzt, dass es in meiner Hauptaktivität angezeigt wird.

Ich habe den folgenden Code in meiner Haupttätigkeit:

public class MainActivity extends sideMenu { 

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

     FrameLayout contentFrameLayout = (FrameLayout) findViewById(R.id.content_frame); 
     getLayoutInflater().inflate(R.layout.activity_main, contentFrameLayout); 

    }} 

When i run the app it crashes when entering main activity and it tells this: 

**Caused by: java.lang.IllegalStateException: This Activity already has an action bar supplied by the window decor. Do not request Window.FEATURE_SUPPORT_ACTION_BAR and set windowActionBar to false in your theme to use a Toolbar instead.** 

It specifies the error is in two places: 
Menu activity - 

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

Main activity - 

    super.onCreate(savedInstanceState); 


If someone can shed some light here i'd be grateful!

Answer 1

Ihr Thema bereits ein ActionBar, so dass Sie es zu NoActionBar konvertieren.

für ganzen App:
öffnen styles.xml und sicherstellen, dass die letzte Zeile der Mutter ein Wort hat NoActionBar zum Beispiel :

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar"> <!-- changed .DarkActionBar to .NoActionBar --> 
<!-- Customize your theme here. --> 
<item name="colorPrimary">@color/colorPrimary</item> 
<item name="colorPrimaryDark">@color/colorPrimaryDark</item> 
<item name="colorAccent">@color/colorAccent</item> 

für eine Aktivität:
Oder du kannst es einfach für eine bestimmte Aktivität im Manifest ändern, indem du dieses Attribut zum Beispiel im Mann hinzufügst Ifest :

android:theme="@style/Theme.AppCompat.Light.NoActionBar" 

Answer 2

Verwendung dieses Thema.

<style name="AppTheme.NoActionBar"> 
    <item name="windowActionBar">false</item> 
    <item name="windowNoTitle">true</item> 
</style>
