I searched a lot of questions , but none of the answers helped me ! I connected an activity with a navigation drawer to a fragment ... but I start from this mistake ! Thanks for your help!

As the Error say: Change the DrawerLayout width to some definite value like 240dp instead of match_parent
See the source Code:
if (widthMode != MeasureSpec.EXACTLY || heightMode != MeasureSpec.EXACTLY) {
if (isInEditMode()) {
// Don't crash the layout editor. Consume all of the space if specified
// or pick a magic number from thin air otherwise.
// TODO Better communication with tools of this bogus state.
// It will crash on a real device.
if (widthMode == MeasureSpec.AT_MOST) {
widthMode = MeasureSpec.EXACTLY;
} else if (widthMode == MeasureSpec.UNSPECIFIED) {
widthMode = MeasureSpec.EXACTLY;
widthSize = 300;
}
if (heightMode == MeasureSpec.AT_MOST) {
heightMode = MeasureSpec.EXACTLY;
}
else if (heightMode == MeasureSpec.UNSPECIFIED) {
heightMode = MeasureSpec.EXACTLY;
heightSize = 300;
}
} else {
throw new IllegalArgumentException(
"DrawerLayout must be measured with MeasureSpec.EXACTLY.");
}

I had a similar issue, during investigation I discovered that it was because HorizontalScrollVIew was in my view hierarchy, try to play with that

Using Navigation Drawer List in Tablayout

I am using a navigation drawer that fetches the album list from picasa web api. I have been trying to implement that same list as the tab items. Can someone please help me with implementing it?
This is the Navigation Drawer item class to show the albums in the navigation drawer.
public class NavDrawerItem {
private String albumId, albumTitle;
// boolean flag to check for recent album
private boolean isRecentAlbum = false;
public NavDrawerItem() {
}
public NavDrawerItem(String albumId, String albumTitle) {
this.albumId = albumId;
this.albumTitle = albumTitle;
}
public NavDrawerItem(String albumId, String albumTitle,
boolean isRecentAlbum) {
this.albumTitle = albumTitle;
this.isRecentAlbum = isRecentAlbum;
}
public String getAlbumId() {
return albumId;
}
public void setAlbumId(String albumId) {
this.albumId = albumId;
}
public String getTitle() {
return this.albumTitle;
}
public void setTitle(String title) {
this.albumTitle = title;
}
public boolean isRecentAlbum() {
return isRecentAlbum;
}
public void setRecentAlbum(boolean isRecentAlbum) {
this.isRecentAlbum = isRecentAlbum;
}
}

I am simple just trying to add icons to the navigation drawer, but this does not work and I am not sure what goes wrong. The application just shuts down. All help is really appreciated!
Here is my log-cat:
05-25 12:27:33.053 3909-3909/oscarorellana.nowwetryitmyway.physicsproject E/AndroidRuntime﹕ FATAL EXCEPTION: main

This was solved with changing this line:

To this line:
row = inflater.inflate(R.layout.custom_row, parent, false);

Navigation Drawer not opening when I follow tutorial code

I am new to android programming. I was trying to build navigation drawer and I followed this tutorial. The navigation drawer is not getting created and I am getting errors and the app is also terminating.
Below is my code
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
private CharSequence mDrawerTitle;
// used to store app title
private CharSequence mTitle;
// slide menu items
private String[] navMenuTitles;

</RelativeLayout> `

Try changing if you are using this in your code
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
to
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
Or simply try changing ActionBarActivity to Activity.
You are not setting the click listener...please do this also
mDrawerList.setOnItemClickListener(new SlideMenuClickListener());

you are getting and null from this line:
getActionBar().setDisplayHomeAsUpEnabled(true);
you need to check why your action bar is null.
can you post your class itself?
does your class extends ActionBarActivity?

Android Navigation Drawer Level

I am having some problem with navigation drawer in Android. So these are the codes with me:
public class NavigationDrawer extends FragmentActivity {
private String[] drawerListViewItems;
private DrawerLayout drawerLayout;
private ListView drawerListView;
private ActionBarDrawerToggle actionBarDrawerToggle;
protected DrawerLayout fullLayout;
protected FrameLayout actContent;
#Override
public void setContentView(final int layoutResID) {
fullLayout = (DrawerLayout) getLayoutInflater().inflate(
R.layout.navigation_drawer, null); // Your base layout here
actContent = (FrameLayout) fullLayout.findViewById(R.id.act_content);
getLayoutInflater().inflate(layoutResID, actContent, true);
super.setContentView(fullLayout);
drawerListViewItems = getResources().getStringArray(R.array.items);
drawerListView = (ListView) findViewById(R.id.left_drawer);
drawerListView.setAdapter(new ArrayAdapter<String>(this,
R.layout.drawer_listview_item, drawerListViewItems));
drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
actionBarDrawerToggle = new ActionBarDrawerToggle(this,
drawerLayout,
R.drawable.ic_drawer,
R.string.drawer_open,
R.string.drawer_close
);
drawerLayout.setDrawerListener(actionBarDrawerToggle);
getActionBar().setDisplayHomeAsUpEnabled(true);
drawerLayout.setDrawerShadow(R.drawable.drawer_shadow,
GravityCompat.START);
drawerListView.bringToFront();
drawerListView.setOnItemClickListener(new DrawerItemClickListener());
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
actionBarDrawerToggle.onConfigurationChanged(newConfig);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (actionBarDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
actionBarDrawerToggle.syncState();
}
private class DrawerItemClickListener implements
ListView.OnItemClickListener {
#Override
public void onItemClick(AdapterView parent, View view, int position,
long id) {
switch (position) {
}
drawerLayout.closeDrawer(drawerListView);
}
}
}
And my xml file:
<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" >
<ListView
android:id="#+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#111"
android:divider="#CCCCCC"
android:dividerHeight="0.5dp"
android:paddingLeft="16dp"
android:paddingRight="16dp" />
<FrameLayout
android:id="#+id/act_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
</FrameLayout>
</android.support.v4.widget.DrawerLayout>
And the string file where I declare the words for navigation drawer item:
<string-array name="items">
<item>Dashboard</item>
<item>Account</item>
<item>Setting</item>
<item>Recurring</item>
<item>Budget</item>
</string-array>
But with these code, the navigation drawer level is only one. What I am trying to do is there will be still sub item under Dashboard, Setting and Budget.
I wonder how to modify it so that the navigation drawer could take in one more level of items.
Thanks in advance.

Steps:
Change ListView to Expandablelistview.
Add subitems for the group items required.
