Changing the background color of the Navigation Drawer dependent on the user click about yourappidea HOT 16 CLOSED

Do you call the notifyDatasetChanged on the adapter ?

2013/11/20 TheoTzaferis [email protected]

Hey,

I have used your Navigation Drawer and its really awesome. The best one
I've used. I modified it a bit so I can have my own backgroundcolor and
don't have to use an image. I added a method, that has the name
createColor and gets a color as an additional paramter to the create
-method.

What I have are 3 sections. The user is able to select one item from each
section and the fragment gets changed dependent on the user selection. This
works without any problems. The filtering works perfectly fine.

The only thing I want to do know is to highlight the selections by also
giving them a blue background. But the problem is that only the settings
that I've defined at the beginning are the ones that get blue

This is my Config

NavDrawerActivityConfiguration navDrawerActivityConfiguration = new NavDrawerActivityConfiguration();
navDrawerActivityConfiguration.setMainLayout(R.layout.activity_main);
navDrawerActivityConfiguration.setDrawerLayoutId(R.id.drawer_layout);
navDrawerActivityConfiguration.setLeftDrawerId(R.id.left_drawer);
navDrawerActivityConfiguration.setNavItems(menu);
navDrawerActivityConfiguration
        .setDrawerShadow(R.drawable.drawer_shadow);
 navDrawerActivityConfiguration.setDrawerOpenDesc(R.string.open_drawer);
 navDrawerActivityConfiguration.setDrawerCloseDesc(R.string.mainTitle);
navDrawerActivityConfiguration.setBaseAdapter(new NavDrawerAdapter(
        this, R.layout.navdrawer_item, menu));
return navDrawerActivityConfiguration;

}

As you can see, when a certain filter is set the Navigation Menu should
change. The logcat, also tells me the set timefilter, socialfilter and
blogfilter. So that would mean, that the app always comes again into the
NavigationDrawreConfiguration but doesn't set it.

I tried so many things like invalidateOptionsmenu and clear the adapter.
But none of them worked. I would be really happy if you could tell me how
exactly I can do that!

Hey. Yes I tried that. Maybe it was just the different place, where I did it? The things I've done were to create a

NavDrawerAdapter navDrawerAdapter;

And then, in the onNavItemSelected I set navDrawerAdapter.notifyDataSetChanged - Is it the wrong place? I have a MainActivity where the navigationconfiguration is locted and a fragment where the whole data gets displayed. Where exactly do I have to set that? When I do it as I said either nothing happens or a NullPointerException is thrown. And it is for this line

this.onNavItemSelected(selectedItem.getId()); in AbstractNavDrawerActivity.java

from yourappidea.

Hey. I'm still stuck to this problem. I'll try to make it more clear. The MainActivity.class has the method getNavDrawerConfiguration where I assign the menu items and sections to a NavDrawerItem object and then configurate it like in your example.

In the MainActivity there is also the method onNavItemSelected Dependend on the case I open up a fragment. Now, when a fragment gets opened I set the options dependent on the click. This works without problems. The fragment gets replaced into a FrameLayout from the activity_main.xml like that: ft.replace(R.id.content_frame, new MainFragment()); After it has changed I would like to refresh the NavDrawer

What I tried was to create a new Adapter.

NavDrawerAdapter navDrawerAdapter

and then, after the commit, calling navDrawerAdapter.notifyDataSetChanged() but that line crashes the app with a NullPointerException - When I try to initialize the variable I have to give a context, textViewReference and the objects I want to pass. But the objects I want to pass are only created in the getNavDrawerConfiguration. So I can't assign them.

I hope this is detailed enough, because this is the last part of the app I need to finish my app!

Hi,

Is it possible for you to send the source code of your project ?

Hi,

I'm unfortunate that it is in fact not. It's a project for a customer. The only thing I could send you would be the MainActivity and the classes I got from you. Would that be enough? I don't think you would need the fragments, would you? The MainActivity is anyway the only class where I'm doing the logic of the Navigation Drawer. The fragments aren't affected by that.

from yourappidea.

And could you create a simple project with the minimal code to reproduce
the issue ?

Thanks in advance. It would be awesome if you could help me! This is the last thing I need for the app

from yourappidea.

Look at this.
But i think this is not the best way.
You should use t the attribute ?activatedBackgroundIndicator to change the
color of the selected item of the list.

best regards
Laurent

Hey. Did you forget to attatch something? Because i cant see anything except your text.
Yeah the avtivatedBackgroundIndicator only works for one item doesnt it? I need it for multiple dependent on the click. Max 3 at once and only 1 per section

from yourappidea.

sorry.

No problem. :) But I still can't see anything except your texts

This is not the best solution because i recreate the adapter each time.
I recreate it because it is an ArrayAdapter and you can't modify it (clear
and add elements).
It would be best to write an Adapter owning a List, instantiate it once
only, and when needed, modify the data inside, and call its method
notifyDataSetChanged().

A thousand thanks! I will use this for my first release and then, in the second release try to use an Adapter owning a List!
