So stellen Sie ToolBar statt ActionBar ein

Question

Ich habe in einer Android-Anwendung eine Schubladennavigation mit Aktionsleiste implementiert. Jetzt möchte ich Toolbar anstelle von Aktionsleiste einfügen, weil es veraltet ist. Aber ich kann das nicht machen.

public class AndroidNavDrawerActivity extends AppCompatActivity 
     implements NavigationDrawerFragment.NavigationDrawerCallbacks { 

    private NavigationDrawerFragment mNavigationDrawerFragment; 
    private CharSequence mTitle; 

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

     mNavigationDrawerFragment = (NavigationDrawerFragment) 
       getSupportFragmentManager().findFragmentById(R.id.navigation_drawer); 
     mTitle = getTitle(); 

     mNavigationDrawerFragment.setUp(
       R.id.navigation_drawer, 
       (DrawerLayout) findViewById(R.id.drawer_layout)); 
    } 

    @Override 
    public void onNavigationDrawerItemSelected(int position) { 
     Fragment fragment; 
     //FragmentManager fragmentManager = getSupportFragmentManager(); // For AppCompat use getSupportFragmentManager 
     switch(position) { 
      default: 
      case 0: 
       fragment = new SocialHistoryActivity(); 
       break; 
      case 1: 
       fragment = new EncounterActivity(); 
       break; 
     } 
     if (fragment != null) { 
      // update the main content by replacing fragments 
      FragmentManager fragmentManager = getSupportFragmentManager(); 
      fragmentManager.beginTransaction() 
        .replace(R.id.container, fragment) 
        .commit(); 
     } 
    } 

    public void onSectionAttached(int number) { 
     switch (number) { 
      case 1: 
       mTitle = getString(R.string.social_history); 
       break; 
      case 2: 
       mTitle = getString(R.string.encounter); 
       break; 
     } 
    } 

    public void restoreActionBar() { 
     ActionBar actionBar = getSupportActionBar(); 
     actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_STANDARD); 
     actionBar.setDisplayShowTitleEnabled(true); 
     actionBar.setTitle(mTitle); 
    } 


    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     if (!mNavigationDrawerFragment.isDrawerOpen()) { 
      restoreActionBar(); 
      return true; 
     } 
     return super.onCreateOptionsMenu(menu); 
    } 

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 

     int id = item.getItemId(); 
     return super.onOptionsItemSelected(item); 
    } 

    public static class PlaceholderFragment extends Fragment { 

     private static final String ARG_SECTION_NUMBER = "section_number"; 

     public static PlaceholderFragment newInstance(int sectionNumber) { 
      PlaceholderFragment fragment = new PlaceholderFragment(); 
      Bundle args = new Bundle(); 
      args.putInt(ARG_SECTION_NUMBER, sectionNumber); 
      fragment.setArguments(args); 
      return fragment; 
     } 

     public PlaceholderFragment() { 
     } 

     @Override 
     public View onCreateView(LayoutInflater inflater, ViewGroup container, 
           Bundle savedInstanceState) { 
      View rootView = inflater.inflate(R.layout.fragment_main, container, false); 
      return rootView; 
     } 

     @Override 
     public void onAttach(Activity activity) { 
      super.onAttach(activity); 
      ((AndroidNavDrawerActivity) activity).onSectionAttached(
        getArguments().getInt(ARG_SECTION_NUMBER)); 
     } 
    } 
} 

Dies ist NavigationDrawerFragment.java

public class NavigationDrawerFragment extends Fragment { 


    private static final String STATE_SELECTED_POSITION = "selected_navigation_drawer_position"; 
    private NavigationDrawerCallbacks mCallbacks; 
    private ActionBarDrawerToggle mDrawerToggle; 

    private DrawerLayout mDrawerLayout; 
    private ListView mDrawerListView; 
    private View mFragmentContainerView; 
    private int mCurrentSelectedPosition = 0; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     if (savedInstanceState != null) { 
      mCurrentSelectedPosition = savedInstanceState.getInt(STATE_SELECTED_POSITION); 
     } 


     // Select the default item. 
     selectItem(mCurrentSelectedPosition); 
    } 

    @Override 
    public void onActivityCreated(Bundle savedInstanceState) { 
     super.onActivityCreated(savedInstanceState); 

     // the fragment has menu items to contribute 
     setHasOptionsMenu(true); 
    } 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
          Bundle savedInstanceState) { 
     mDrawerListView = (ListView) inflater.inflate(
       R.layout.fragment_navigation_drawer, container, false); 
     mDrawerListView.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
      @Override 
      public void onItemClick(AdapterView parent, View view, int position, long id) { 
       selectItem(position); 
      } 
     }); 
     mDrawerListView.setAdapter(new ArrayAdapter(
       getActionBar().getThemedContext(), 
       android.R.layout.simple_list_item_activated_1, 
       android.R.id.text1, 
       new String[]{ 
         getString(R.string.social_history), 
         getString(R.string.encounter) 
       })); 
     mDrawerListView.setItemChecked(mCurrentSelectedPosition, true); 
     return mDrawerListView; 
    } 

    private ActionBar getActionBar() { 
     return ((AppCompatActivity) getActivity()).getSupportActionBar(); 
    } 

    public boolean isDrawerOpen() { 
     return mDrawerLayout != null && mDrawerLayout.isDrawerOpen(mFragmentContainerView); 
    } 


    public void setUp(int fragmentId, DrawerLayout drawerLayout) { 
     mFragmentContainerView = getActivity().findViewById(fragmentId); 
     mDrawerLayout = drawerLayout; 
     // set up the drawer's list view with items and click listener 
     ActionBar actionBar = getActionBar(); 
     actionBar.setDisplayHomeAsUpEnabled(true); 
     actionBar.setHomeButtonEnabled(true); 
     // ActionBarDrawerToggle ties together the the proper interactions 
     // between the navigation drawer and the action bar app icon. 
     mDrawerToggle = new ActionBarDrawerToggle(
       getActivity(), 
       mDrawerLayout, 
       null, 
       R.string.navigation_drawer_open, 
       R.string.navigation_drawer_close 
     ) { 
      @Override 
      public void onDrawerClosed(View drawerView) { 
       super.onDrawerClosed(drawerView); 
       if (!isAdded()) { 
        return; 
       } 
       getActivity().supportInvalidateOptionsMenu(); 
      } 

      @Override

       super.onDrawerOpened(drawerView); 
       if (!isAdded()) { 
        return; 
       } 
       getActivity().supportInvalidateOptionsMenu(); 
      } 
     }; 


     mDrawerLayout.post(new Runnable() { 
      @Override 
      public void run() { 
       mDrawerToggle.syncState(); 
      } 
     }); 
     mDrawerLayout.setDrawerListener(mDrawerToggle); 
     mDrawerToggle.setDrawerIndicatorEnabled(true); 
    } 

    private void selectItem(int position) { 
     mCurrentSelectedPosition = position; 
     if (mDrawerListView != null) { 
      mDrawerListView.setItemChecked(position, true); 
     } 
     if (mDrawerLayout != null) { 
      mDrawerLayout.closeDrawer(mFragmentContainerView); 
     } 
     if (mCallbacks != null) { 
      mCallbacks.onNavigationDrawerItemSelected(position); 
     } 
    } 

    @Override 
    public void onAttach(Activity activity) { 
     super.onAttach(activity); 
     try { 
      mCallbacks = (NavigationDrawerCallbacks) activity; 
     } catch (ClassCastException e) { 
      throw new ClassCastException("Activity must implement NavigationDrawerCallbacks."); 
     } 
    } 

    @Override 
    public void onDetach() { 
     super.onDetach(); 
     mCallbacks = null; 
    } 

    @Override 
    public void onSaveInstanceState(Bundle outState) { 
     super.onSaveInstanceState(outState); 
     outState.putInt(STATE_SELECTED_POSITION, mCurrentSelectedPosition); 
    } 

    @Override

</RelativeLayout> 

Answer 1

eine Symbolleiste Layout zunächst von erstellen: toolbar.xml

<?xml version="1.0" encoding="utf-8"?> 
<android.support.v7.widget.Toolbar 
    android:layout_height="56dp" 
    android:layout_width="match_parent" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    android:background="@color/colorPrimary" 
    xmlns:android="http://schemas.android.com/apk/res/android"> 
    <LinearLayout 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:orientation="horizontal" 
     android:gravity="center_vertical" 
     >  

     <TextView 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="Login" 
    android:textSize="18sp" 
    android:gravity="center|center_vertical" 
    android:layout_weight="1" 
    android:textColor="@android:color/white" 
    android:textStyle="bold" 
    android:visibility="visible" 
    android:id="@+id/toolbar_title" />  

</LinearLayout> 
</android.support.v7.widget.Toolbar> 

es In die Aktivität, die du möchtest se:

<include 
     android:id="@+id/tool_bar" 
     layout="@layout/toolbar" 
     android:layout_height="wrap_content" 
     android:layout_width="match_parent" 
     /> 

Answer 2

1) Foll. In Sie

<android.support.design.widget.AppBarLayout 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:theme="@style/AppTheme.AppBarOverlay"> 

     <android.support.v7.widget.Toolbar 
      android:id="@+id/toolbar" 
      android:layout_width="match_parent" 
      android:layout_height="?attr/actionBarSize" 
      app:title="Hello" 
      app:titleTextColor="#FF0000" 
      android:background="?attr/colorPrimary" /> 

    </android.support.design.widget.AppBarLayout> 

3) Aktivität des onCreate() -Methode folgende Zeilen hinzufügen - - Abhängigkeiten zu Ihrem build.gradle (App-Ebene) -

compile 'com.android.support:appcompat-v7:23.x.x' 
compile 'com.android.support:design:23.x.x' 

2) In der XML-Datei hinzufügen

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

UPDATE

Wenn Sie Symbolleiste wollen Alle Aktivitäten fügen dann diesen XML-Teil in die entsprechende XML-Datei und den JAVA-Teil hinzufügen in die entsprechende Aktivität ein.

In diesem Fall können Sie den zweiten Punkt (XML-Teil) in "activity_main" und den dritten Punkt (JAVA-Teil) in "AndroidNavDrawerActivity" hinzufügen.

Dies wird Symbolleiste als ActionBar hinzufügen. Hoffe es wird helfen :)
