Question

I am developing an application where i specifically need to change the navigation drawer Items on user selection.

For eg: I have an application which has sports grid view with 6 Different sports to choose from. `1> Cricket 2> Football 3> Baseball 4> Tennis 5> Hockey 6> Basketball.`
When the user selects `Cricket-> i want to change the Navigation items to 
1> Bat 
2>Ball 
3>Pitch info 
4> Rules etc.`

When the user selects `2> Football` the navigation drawer items should change to.

    1> Football info
    2> Rules
    3> Doging tricks etc..
When user selects `3> Baseball` the navigation drawer items should change to 

    1> Baseball info
    2> Baseball bat info
    3> Baseball Player info
    etc

Is it possible to do so in android.

Answer 1

The Navigation Drawer is a fragment with a listview in it. As described here: http://developer.android.com/training/implementing-navigation/nav-drawer.html

So you can just change the array of the list and you are ready to go. (code from the link above)

mPlanetTitles = getResources().getStringArray(R.array.planets_array);

mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout); mDrawerList = (ListView) findViewById(R.id.left_drawer);

// Set the adapter for the list view mDrawerList.setAdapter(new ArrayAdapter(this, R.layout.drawer_list_item, mPlanetTitles));
