I downloaded a sample code from android developer site. The code was to implement the drawer menu using fragments images from the drawer folder. I would like to know how to use fragments to get xml layouts from the layout folder. Here is the MainActivity code:
public class MainActivity extends Activity {
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.left_drawer);
// set a custom shadow that overlays the main content when the drawer opens
mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
// set up the drawer's list view with items and click listener
mDrawerList.setAdapter(new ArrayAdapter<String>(this,
R.layout.drawer_list_item, mPlanetTitles));
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
// enable ActionBar app icon to behave as action to toggle nav drawer
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
// ActionBarDrawerToggle ties together the the proper interactions
// between the sliding drawer and the action bar app icon
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) {
getActionBar().setTitle(mTitle);
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
public void onDrawerOpened(View drawerView) {
getActionBar().setTitle(mDrawerTitle);
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
if (savedInstanceState == null) {
selectItem(0);
}
}
#Override

return super.onPrepareOptionsMenu(menu);
}
#Override

if (intent.resolveActivity(getPackageManager()) != null) {
startActivity(intent);
} else {
Toast.makeText(this, R.string.app_not_available, Toast.LENGTH_LONG).show();
}
return true;

here you are defining a fragments layout from XML file. Is that what you are asking for?

I am using a navigation drawer that I fill from a string-array. Now I want that the first item of the navigation drawer will be always opened, when the activity of the navigation drawer is starting.
My activity with the navigation drawer (It is almost the same of the official documentation) :
public class MainActivity extends Activity {
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.main_menu);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.left_drawer);
// set a custom shadow that overlays the main content when the drawer opens
mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
// set up the drawer's list view with items and click listener
mDrawerList.setAdapter(new ArrayAdapter<String>(this,
R.layout.drawer_list_item, mPlanetTitles));
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
// enable ActionBar app icon to behave as action to toggle nav drawer
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
// ActionBarDrawerToggle ties together the the proper interactions
// between the sliding drawer and the action bar app icon
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 */

// If the nav drawer is open, hide action items related to the content view
boolean drawerOpen = mDrawerLayout.isDrawerOpen(mDrawerList);
// menu.findItem(R.id.action_websearch).setVisible(!drawerOpen);
return super.onPrepareOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {

}
The layout:
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- The main content view -->
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!-- The navigation drawer -->
<ListView android:id="#+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
android:background="#111"/>
</android.support.v4.widget.DrawerLayout>
This is the activity of the first item:
public class Start extends Fragment implements OnClickListener {
private Button start;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.start, container, false);
//Button
start = (Button) rootView.findViewById(R.id.startButton);
start.setOnClickListener(this);
return rootView;
}
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.startButton:
Intent intent = new Intent(v.getContext(), TabataStartAuswahl.class);
startActivity(intent);
break;
default:
break;
}
// TODO Auto-generated method stub
}
}
I want if the MainActivity is starting the first item of the navigation drawer/list (in my case: the Start - Activity) should always be opened. How can I handle this?
Try calling selectItem(0) in your onCreate() method, after all the initializations.
Working from this android example, I've attempted to create an app that uses the support version (android.support.v4 and android.support.v7).
The example creates a menu drawer that looks like this
and my code gets this
Notice the icon is different and the way it moves is different, well in my version it doesn't move.
Example code
public class MainActivity extends Activity {
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
private CharSequence mDrawerTitle;
private CharSequence mTitle;
private String[] mPlanetTitles;
#Override

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.left_drawer);
// set a custom shadow that overlays the main content when the drawer opens
mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
// set up the drawer's list view with items and click listener
mDrawerList.setAdapter(new ArrayAdapter<String>(this,
R.layout.drawer_list_item, mPlanetTitles));
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
// enable ActionBar app icon to behave as action to toggle nav drawer
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
// ActionBarDrawerToggle ties together the the proper interactions

Does anyone know why its not using my toggle icon or moving? Or is it that you can't do it like that using the support libraries?
I'm still investigating what I missed and will update this answer accordingly. Though as #kaedill mentions it is possible using the support libraries.
Here is a full copy of the Google example, edited by myself to use the support libraries.

I have tested this and it works as it should on a Gingerbread device.
I am going to go through the changes in my app and figure out what I did wrong.
Update
After a painful dissection of my original code, I ported my code into the working example and a diff showed my error.
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
// Sync the toggle state after onRestoreInstanceState has occurred.
mDrawerToggle.syncState();
}
My original code had not overridden the onPostCreate method. An annoying little bug to find! Hope it helps someone else out in the future.
You can do it with the support libraries. The only difference I can see from my working version with the ActionbarActivity is a call to super like this:
public void onDrawerClosed(View drawerView)
{
super.onDrawerClosed(drawerView);
getSupportActionBar().setTitle(mTitle);
supportInvalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
Log("onDrawerOpened()");
}
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
getSupportActionBar().setTitle(mDrawerTitle);
supportInvalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
Log("onDrawerOpened()");
}
Did you copy the ic_drawer drawable from the example to your project? I think yes because the code should no compile without that drawable, but when I've implemented DrawerLayout in my app, I had to copy that drawable inside my resources.
I am new in Android world. I have followed this tutorial to create a swipe menu but the items of this menu just show an image. I want to link every single one to a new activity, is this possible?

yes you can do that in onOptionsItemSelected event.
onOptionsItemSelected has a paremeter of type MenuItem . you can see the paremeter here onOptionsItemSelected(MenuItem item).
Just pick item.getTitle and do what you want according to the selected item
Replace OtherActivity.class and anotherActivity.class with your actual activity class names and you are done.
#Override
public boolean onOptionsItemSelected(MenuItem item)
{
if (item.getTitle()=="View 1")
{
Intent newActivity = new Intent(this,OtherActivity.class );
startActivity(newActivity);
}
else
{
Intent newActivity = new Intent(this,anotherActivity.class);
startActivity(newActivity);
}
return MenuChoice(item);
}
Can someone suggest me a tutorial how to create a BaseActivity for the Android Navigation Drawer ?
Or can anyone post a sample BaseActivity for the Navigation Drawer including the layout ?

You can achieve this with the help of fragments. Go through following which have sample code and video tutorial.

I have one problem, how to implement a merchandising display before starting my navigation drawer. this is my code. Thanks for help guys.
This is my code merchan, but is wrong, I want to call this screen before the application itself, which is basically a navigation drawer.
public class Merchan extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.merchan);
Thread logoTimer = new Thread() {
public void run() {
try {
sleep(3000);
Intent menuIntent = new Intent("com.codehevea.menu.Main");
startActivity(menuIntent);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
finish();
}
}
};
logoTimer.start();
}
#Override
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();
}
}
And this is my principal class. It should boot screen after merchandising.
public class Main extends Activity {
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
private CharSequence mDrawerTitle;
private CharSequence mTitle;
private String[] mMenuTitles;
#Override

setContentView(R.layout.activity_main);
mTitle = mDrawerTitle = getTitle();

// set a custom shadow that overlays the main content when the drawer
// opens
mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow,
GravityCompat.START);
// set up the drawer's list view with items and click listener
mDrawerList.setAdapter(new ArrayAdapter<String>(this,
R.layout.drawer_list_item, mMenuTitles));
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
// enable ActionBar app icon to behave as action to toggle nav drawer

You're using the wrong Intent constructor. Change it to something like:
Intent menuIntent = new Intent(this, com.codehevea.menu.Main.class);
Note, if the current and target class are in the same package, you don't need the package name, so:
Intent menuIntent = new Intent(this, Main.class);
