ActionBarActivity mit ActionBarDrawerToggle - keine Verwendung von drawerImageRes

Question

In diesem Beispiel habe ich versucht, eine App zu erstellen, die die Support-Version (android.support.v4 und android.support.v7) verwendet.

Das Beispiel erstellt ein Menü Schublade, die wie diese diese

Hinweis

und mein Code bekommt sieht das Symbol anders ist und so, wie es sich bewegt, ist anders, gut in meiner Version bewegt es sich nicht.

Beispielcode

public class MainActivity extends Activity { 
    private DrawerLayout mDrawerLayout; 
    private ListView mDrawerList; 
    private ActionBarDrawerToggle mDrawerToggle; 

    private CharSequence mDrawerTitle;

Weiß jemand, warum seine nicht mein Toggle Symbol oder Verschieben mit? Oder können Sie das mit den Support-Bibliotheken nicht so machen?

Answer 1

Ich untersuche immer noch was ich verpasst habe und werde diese Antwort entsprechend aktualisieren. Obwohl @ Kaedill erwähnt, ist es möglich, die Support-Bibliotheken zu verwenden.

Hier ist eine vollständige Kopie des Google-Beispiels, das von mir selbst bearbeitet wurde, um die Support-Bibliotheken zu verwenden.

public class MainActivity extends ActionBarActivity { 
    private DrawerLayout mDrawerLayout; 
    private ListView mDrawerList; 
    private ActionBarDrawerToggle mDrawerToggle; 

    private CharSequence mDrawerTitle; 
    private CharSequence mTitle; 
    private String[] mPlanetTitles; 

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

     mTitle = mDrawerTitle = getTitle(); 
     mPlanetTitles = getResources().getStringArray(R.array.planets_array); 
     mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout); 
     mDrawerList = (ListView) findViewById(R.id.left_drawer); 

     // set a custom shadow that overlays the main content when the drawer opens 
     mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START); 
     // set up the drawer's list view with items and click listener 
     mDrawerList.setAdapter(new ArrayAdapter<String>(this, 
       R.layout.drawer_list_item, mPlanetTitles)); 
     mDrawerList.setOnItemClickListener(new DrawerItemClickListener()); 

     // enable ActionBar app icon to behave as action to toggle nav drawer 
     getSupportActionBar().setDisplayHomeAsUpEnabled(true); 
     getSupportActionBar().setHomeButtonEnabled(true); 

     // ActionBarDrawerToggle ties together the the proper interactions 
     // between the sliding drawer and the action bar app icon 
     mDrawerToggle = new ActionBarDrawerToggle(

     mDrawerToggle.syncState(); 
    } 

    @Override 
    public void onConfigurationChanged(Configuration newConfig) { 
     super.onConfigurationChanged(newConfig);

     public static final String ARG_PLANET_NUMBER = "planet_number"; 

     public PlanetFragment() { 
      // Empty constructor required for fragment subclasses 
     } 

     @Override 
     public View onCreateView(LayoutInflater inflater, ViewGroup container, 
       Bundle savedInstanceState) { 
      View rootView = inflater.inflate(R.layout.fragment_planet, container, false); 
      int i = getArguments().getInt(ARG_PLANET_NUMBER); 
      String planet = getResources().getStringArray(R.array.planets_array)[i]; 

      int imageId = getResources().getIdentifier(planet.toLowerCase(Locale.getDefault()), 
          "drawable", getActivity().getPackageName()); 
      ((ImageView) rootView.findViewById(R.id.image)).setImageResource(imageId); 
      getActivity().setTitle(planet); 
      return rootView; 
     } 
    } 
} 

Ich habe dies getestet und es funktioniert so, wie es auf einem Gingerbread-Gerät sollte.

Ich gehe die Änderungen in meiner App durch und finde heraus, was ich falsch gemacht habe.

aktualisieren

Nach einer schmerzhaften Zergliederung meiner ursprünglichen Code, portiert ich meinen Code in das Arbeitsbeispiel und ein diff mein Fehler zeigte.

@Override 
protected void onPostCreate(Bundle savedInstanceState) { 
    super.onPostCreate(savedInstanceState); 
    // Sync the toggle state after onRestoreInstanceState has occurred. 
    mDrawerToggle.syncState(); 
} 

Mein ursprünglicher Code hatte die onPostCreate Methode nicht außer Kraft gesetzt. Ein nerviger kleiner Bug zum finden! Hoffe es hilft jemand anderem in der Zukunft.

Answer 2

Sie können es mit den Support-Bibliotheken tun. Der einzige Unterschied, den ich von meiner Arbeitsversion mit dem ActionbarActivity sehen kann, ist ein Aufruf von super wie folgt aus:

public void onDrawerClosed(View drawerView) 
{ 
    super.onDrawerClosed(drawerView); 
    getSupportActionBar().setTitle(mTitle); 
    supportInvalidateOptionsMenu(); // creates call to onPrepareOptionsMenu() 
    Log("onDrawerOpened()"); 
} 

public void onDrawerOpened(View drawerView) { 
     super.onDrawerOpened(drawerView); 
     getSupportActionBar().setTitle(mDrawerTitle); 
     supportInvalidateOptionsMenu(); // creates call to onPrepareOptionsMenu() 
     Log("onDrawerOpened()"); 
} 

Answer 3

Haben Sie den ic_drawer ziehbar aus dem Beispiel zu einem Projekt kopieren? Ich denke ja, weil der Code nicht kompilieren sollte, ohne dass es drawbar ist, aber wenn ich DrawerLayout in meiner App implementiert habe, musste ich das in meine Ressourcen kopieren.
