How to implement navigation drawer with fragments master detail

Question

i have get the sample navigation drawer from this site : http://www.androidhive.info/2013/11/android-sliding-menu-using-navigation-drawer/

and the master detail from here : http://wptrafficanalyzer.in/blog/itemclick-handler-for-listfragment-in-android/

the error LogCat oncreateview(inflac....) the view can not be created

me i have try that

    //the main activiry as Activity:

Answer 1

I was confused by this, too. I set up the Navigation Drawer to navigate between major sections of my app. Then I wanted one of those major sections to be set up as Master/Detail. I knew it was possible, since this is basically what Gmail is, but was having a hard time putting what I had already built together with what Eclipse spits out when generating a Master/Detail Activity.

I couldn't just launch the ItemListFragment (Master/Detail) from the MainActivity (Navigation Drawer), because ItemListFragment wants to attach to ItemListActivity, not MainActivity, and a fragment can't have two Activities.

I finally found a tutorial on it that actually used the two design ideas together: http://blog.evizija.si/android-layout/

I just followed their example and got my UI working as desired in about 5 minutes. It's actually incredibly simple. You make MasterActivity look a bit more like the generated ItemListActivity (ie. implement TaskListFragment.Callbacks, copy over the onItemSelected method, and a chuck of onCreate) and you're done!

I hope this helps solve your problem! Happy coding!

UPDATE : Elaborating on the steps involved (info from link), based on feedback in comments on improving my answer.

(1) Make your drawer activity and fragments, lets call them MainActivity and some fragments we don't care about here. Personally, I would create an empty Fragment, like ItemFragement for example, to be a place holder for the Master/Detail while I get the Drawer up and running. Then once the Drawer is working as desired, tackle the Master/Detail and linking them.

(2) Use the IDE wizard (I'm running Eclipse) to make the activities and fragments of master/detail flow. I'll refer to them by their default names: ItemListActivity, ItemListFragement, ItemDetailActivity, ItemDetailFragment.

(3) If you've used Master/Detail before, you know most of your logic goes into the fragment. This is still true when combining Master/Detail with Drawer. Note, at this point there is no connection between our MainActivity and our Master/Detail flow, and the later may not even be accessible in the UI.

(4) Key Concept: To connect the Drawer with the List, our MainActivity is going to be the hosting Activity for ItemListFragment (rather than the current ItemListActivity). To make this work, we just copy over some of the Master/Detail magic created by the wizard FROM ItemListActivity INTO MainActivity.

(5) Specifically:

(5A) MainActivity implements ItemListFragment.Callbacks (or EmployeeListFragment.Callbacks, AlbumListFragment.Callbacks, whatever you are listing) and implement onItemSelected method

 public class MainActivity extends Activity implements OnItemClickListener, ItemListFragment.Callbacks { 

(5B) Copy part of code from onCreate in ItemListActivity and paste it to onCreate in MainActivity. This part:

 if (findViewById(R.id.item_detail_container) != null) { // The detail container view will be present only in the // large-screen layouts (res/values-large and // res/values-sw600dp). If this view is present, then the // activity should be in two-pane mode. mTwoPane = true; // In two-pane mode, list items should be given the // 'activated' state when touched. ((ItemListFragment) getFragmentManager() .findFragmentById(R.id.item_list)) .setActivateOnItemClick(true); } 

(5C) Also copy onItemSelected method from ItemListActivity and paste it into MainActivity. You will already have an onItemSelected method if you told Eclipse to "add unimplemented methods" in response to the error that would have been raised after Step 5A. If you don't, copy over the whole method. ( this step edited in response to a question in comments ) Code:

 if (mTwoPane) { // In two-pane mode, show the detail view in this activity by // adding or replacing the detail fragment using a // fragment transaction. Bundle arguments = new Bundle(); arguments.putString(ItemDetailFragment.ARG_ITEM_ID, id); ItemDetailFragment fragment = new ItemDetailFragment(); fragment.setArguments(arguments); getFragmentManager().beginTransaction() .replace(R.id.item_detail_container, fragment) .commit(); } else { // In single-pane mode, simply start the detail activity // for the selected item ID. Intent detailIntent = new Intent(this, ItemDetailActivity.class); detailIntent.putExtra(ItemDetailFragment.ARG_ITEM_ID, id); startActivity(detailIntent); } 

(6) Then the last step is to have MainActivity (the Drawer) open ItemListFragment. If you already have a placeholder Fragment launching (like ItemFragement suggested in Step 1), this is just a matter of replacing ItemFragment with ItemListFragment in the onNavigationDrawerItemSelected method.

Hope that's clear. If not, the original link might do a better job explaining than I did. Just skim to the bottom where the blogger talks about adding the list activity to their drawer activity.

cheers.
