ActionBarActivity con ActionBarDrawerToggle – No utiliza drawerImageRes
Trabajando desde este ejemplo de Android , he intentado crear una aplicación que utilice la versión de soporte (android.support.v4 y android.support.v7).
El ejemplo crea un cajón de menú que se ve así
- ActionBarActivity botón de retroceso no estallar de backstack
- La aplicación se bloquea al extender ActionBarActivity
- GetSupportActionBar (). SetCustomView (vista) no llena toda la barra de acciones
- Añadir imagen al lado izquierdo de la barra de acción?
- ActionBarActivity requestFeature se debe llamar antes de agregar contenido
Y mi código obtiene este
Observe que el icono es diferente y la forma en que se mueve es diferente, así que en mi versión no se mueve.
Ejemplo de código
public class MainActivity extends Activity { 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 getActionBar().setDisplayHomeAsUpEnabled(true); getActionBar().setHomeButtonEnabled(true); // ActionBarDrawerToggle ties together the the proper interactions // between the sliding drawer and the action bar app icon mDrawerToggle = new ActionBarDrawerToggle( this, /* host Activity */ mDrawerLayout, /* DrawerLayout object */ R.drawable.ic_drawer, /* nav drawer image to replace 'Up' caret */ R.string.drawer_open, /* "open drawer" description for accessibility */ R.string.drawer_close /* "close drawer" description for accessibility */ ) { public void onDrawerClosed(View view) { getActionBar().setTitle(mTitle); invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu() } public void onDrawerOpened(View drawerView) { getActionBar().setTitle(mDrawerTitle); invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu() } }; mDrawerLayout.setDrawerListener(mDrawerToggle); if (savedInstanceState == null) { selectItem(0); } } @Override public boolean onCreateOptionsMenu(Menu menu) { MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.main, menu); return super.onCreateOptionsMenu(menu); } /* Called whenever we call invalidateOptionsMenu() */ @Override public boolean onPrepareOptionsMenu(Menu menu) { // If the nav drawer is open, hide action items related to the content view boolean drawerOpen = mDrawerLayout.isDrawerOpen(mDrawerList); menu.findItem(R.id.action_websearch).setVisible(!drawerOpen); return super.onPrepareOptionsMenu(menu); } @Override public boolean onOptionsItemSelected(MenuItem item) { // The action bar home/up action should open or close the drawer. // ActionBarDrawerToggle will take care of this. if (mDrawerToggle.onOptionsItemSelected(item)) { return true; } // Handle action buttons switch(item.getItemId()) { case R.id.action_websearch: // create intent to perform web search for this planet Intent intent = new Intent(Intent.ACTION_WEB_SEARCH); intent.putExtra(SearchManager.QUERY, getActionBar().getTitle()); // catch event that there's no activity to handle intent if (intent.resolveActivity(getPackageManager()) != null) { startActivity(intent); } else { Toast.makeText(this, R.string.app_not_available, Toast.LENGTH_LONG).show(); } return true; default: return super.onOptionsItemSelected(item); } } /* The click listner for ListView in the navigation drawer */ private class DrawerItemClickListener implements ListView.OnItemClickListener { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { selectItem(position); } } private void selectItem(int position) { // update the main content by replacing fragments Fragment fragment = new PlanetFragment(); Bundle args = new Bundle(); args.putInt(PlanetFragment.ARG_PLANET_NUMBER, position); fragment.setArguments(args); FragmentManager fragmentManager = getFragmentManager(); fragmentManager.beginTransaction().replace(R.id.content_frame, fragment).commit(); // update selected item and title, then close the drawer mDrawerList.setItemChecked(position, true); setTitle(mPlanetTitles[position]); mDrawerLayout.closeDrawer(mDrawerList); } @Override public void setTitle(CharSequence title) { mTitle = title; getActionBar().setTitle(mTitle); } /** * When using the ActionBarDrawerToggle, you must call it during * onPostCreate() and onConfigurationChanged()... */ @Override protected void onPostCreate(Bundle savedInstanceState) { super.onPostCreate(savedInstanceState); // Sync the toggle state after onRestoreInstanceState has occurred. mDrawerToggle.syncState(); } @Override public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); // Pass any configuration change to the drawer toggls mDrawerToggle.onConfigurationChanged(newConfig); } /** * Fragment that appears in the "content_frame", shows a planet */ public static class PlanetFragment extends Fragment { 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; } } }
Mi código
public class MainActivity extends ActionBarActivity { @Override protected void onCreate(Bundle savedInstanceState) { requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS); super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mTitle = mDrawerTitle = getTitle(); 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); // Get the power manager mWL = ((PowerManager) getSystemService(Context.POWER_SERVICE)) .newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK, "cell hunter"); sMe = this; mDb = new DatabaseHelper(this); mMakers = new HashMap<Marker, String>(); // 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( this, /* host Activity */ mDrawerLayout, /* DrawerLayout object */ R.drawable.ic_drawer, /* nav drawer image to replace 'Up' caret */ R.string.app_name, /* "open drawer" description for accessibility */ R.string.add_data /* "close drawer" description for accessibility */ ) { public void onDrawerClosed(View view) { getSupportActionBar().setTitle(mTitle); supportInvalidateOptionsMenu(); // creates call to onPrepareOptionsMenu() Log("onDrawerClosed()"); } public void onDrawerOpened(View drawerView) { getSupportActionBar().setTitle(mDrawerTitle); supportInvalidateOptionsMenu(); // creates call to onPrepareOptionsMenu() Log("onDrawerOpened()"); } }; mDrawerLayout.setDrawerListener(mDrawerToggle); } }
¿Alguien sabe por qué no está usando mi icono de conmutación o en movimiento? ¿O es que no puedes hacerlo así usando las bibliotecas de soporte?

Todavía estoy investigando lo que me perdí y actualizaré esta respuesta en consecuencia. Aunque @kaedill menciona que es posible utilizar las bibliotecas de soporte.
Aquí hay una copia completa del ejemplo de Google, editado por mí mismo para usar las bibliotecas de soporte.
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);

// creates call to onPrepareOptionsMenu() } }; mDrawerLayout.setDrawerListener(mDrawerToggle); if (savedInstanceState == null) { selectItem(0); } } @Override public boolean onCreateOptionsMenu(Menu menu) { MenuInflater inflater = getMenuInflater();

He probado esto y funciona como debería en un dispositivo de pan de jengibre.
Voy a pasar por los cambios en mi aplicación y averiguar lo que hice mal.
Actualizar
Después de una disección dolorosa de mi código original, porté mi código en el ejemplo de trabajo y un diff mostró mi error.
@Override protected void onPostCreate(Bundle savedInstanceState) { super.onPostCreate(savedInstanceState); // Sync the toggle state after onRestoreInstanceState has occurred. mDrawerToggle.syncState(); }
Mi código original no había anulado el método onPostCreate
. ¡Un pequeño insecto molesto a encontrar! Espero que ayude a alguien más en el futuro.
Puede hacerlo con las bibliotecas de soporte. La única diferencia que puedo ver de mi versión de trabajo con ActionbarActivity es una llamada a super como esta:
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()"); }
¿Ha copiado el dibujo ic_drawer del ejemplo a su proyecto? Creo que sí, porque el código no debería compilar sin que se pueda dibujar, pero cuando he implementado DrawerLayout en mi aplicación, tuve que copiar ese dibujable dentro de mis recursos.
