Failed to change the Up cursor next to the application icon in the ActionBar in my navigation box

Question

I am currently trying to implement a new NavigationDrawer in accordance with the rules of Google IO 2013. I am using ActionbarSherlock. The code works well. The only problem is that I cannot switch the “up” carriage next to my application icon when the navigation drawer is pulled out. I embed all my code below. Please help.

public class MainActivity extends SherlockFragmentActivity { 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.drawer); mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START); mDrawerList.setAdapter(new ArrayAdapter<String>(this, R.layout.drawer_list_item, mPlanetTitles)); mDrawerList.setOnItemClickListener(new DrawerItemClickListener()); 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) { getSupportActionBar().setTitle(mTitle); supportInvalidateOptionsMenu(); } public void onDrawerOpened(View drawerView) { getSupportActionBar().setTitle(mDrawerTitle); supportInvalidateOptionsMenu(); } }; getSupportActionBar().setDisplayHomeAsUpEnabled(true); getSupportActionBar().setHomeButtonEnabled(true); mDrawerLayout.setDrawerListener(mDrawerToggle); if (savedInstanceState == null) { selectItem(0); } new Thread(new Runnable() { @Override public void run() { prefs = getPreferences(MODE_PRIVATE); opened = prefs.getBoolean(OPENED_KEY, false); if(opened == false) { mDrawerLayout.openDrawer(mDrawerList); } } }).start(); } @Override public boolean onCreateOptionsMenu(Menu menu) { MenuInflater inflater = getSupportMenuInflater();

Answer 1

If you do not need 3 lines to move (for example, in the gmail application), you can simply add:

 <item name="homeAsUpIndicator">@drawable/ic_drawer</item> <item name="android:homeAsUpIndicator">@drawable/ic_drawer</item> 

in your activity topic. I prefer this to use another library in my application.

ic_drawer can be downloaded here: http://developer.android.com/training/implementing-navigation/nav-drawer.html

Answer 2

try calling syncState in the switch box, for example:

  @Override protected void onPostCreate(Bundle savedInstanceState) { super.onPostCreate(savedInstanceState); //your ActionBarDrawerToggle is below mDrawerToggle.syncState(); } 

or immediately after its creation.

Answer 3

I had the same problem and did some research on this topic. It doesn't seem easy to get the carriage to work correctly on older SDKs. In short, there is a guy who has a reflection example of execution:

https://github.com/nicolasjafelle/SherlockNavigationDrawer

I tested it and it works great for me, even on Android 2.x!

Answer 4

I have a carriage removed in 4.x devices but not for 2.x devices. The repository is here if you need it: https://github.com/bcrider/NavigationDrawerSherlocked

This is just a sample that Google provided to me, which I modified using ActionBarSherlock, as you did. I fixed the problem with the method (onOptionsItemSelected) in the sample, which initially did not allow the icon with the button pressed to do something after the ActionBarSherlock was included in the application.

Hope this helps!
