How should i proceed.Please Help.

}

onPostCreate will be executed immediately after onCreate. You're accessing a member variable called mDrawerToggle in your onPostCreate, but it is not assigned before onPostCreate is called. It is normal convention to assign all your views to member variables during onCreate immedately after you call setContentView. In your case, it's being assigned in a method called "set" where I can't see that it's ever being called.
Try moving all the view-related code from set into onCreate.

Custom navigation drawer list view

Hi i'm new to the android world and i generated a navigation drawer with the default template in android studio.I'm looking for a way to make section in my listview like this :![enter image description here][1]
How i want my listview to be : https://camo.githubusercontent.com/7043b4240e1be50bb68b3f101c1f9815c9be0f11/68747470733a2f2f7261772e6769746875622e636f6d2f6e656f6b7265652f4d6174657269616c4e617669676174696f6e4472617765722f6d61737465722f73637265656e312e6a7067
Here is the code of my fragment,i really don't know how to do this and i want to have the image on the top with the email like the photo with two section:
public class NavigationDrawerFragment extends Fragment {

i have to finish this to next week cause it's a project at school :(

You can customize the navigation drawer with the proper layout you need.
You can inflate any layout with in the drawer and make proper logic to implement.
You need to modify the method
onCreateView();
For a particular layout you can modify as -
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView= inflater.inflate(
R.layout.fragment_navigation_drawer_layout, container, false);
return rootView;
}
Here
fragment_navigation_drawer_layout
is the layout you want to set.

I want to add icon in front of each item of the list view but i dont know how to do this because i dont understand the whole code of the navigation drawer

Create a custom ArrayAdapter and use a custom layout inside it which has an ImageView and a TextView

Try this
The xml file(call it whatever you want):
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium"
android:text="Medium Text"
android:id="#+id/textViewListItem"
android:layout_marginTop="25dp"
android:layout_marginLeft="10dp"
android:layout_gravity="center_horizontal" />
<ImageView
android:layout_width="45dp"
android:layout_height="45dp"
android:layout_marginLeft="15dp"
android:layout_marginTop="-40dp"
android:id="#+id/imageView"
android:src="#drawable/ic_launcher" />
</LinearLayout>
Create a class that will be your adapter, how your list wants to be(have an imageview, have 3 textviews, etc)
public class ListAdapter extends Activity {
private int imageId;
private String itemName;
public ListaAdapter(int imageId, String itemName) {
super();
this.imageId = imageId;
this.itemName = itemName;
}
public int getImageId() {
return imageId;
}
public void setImageId(int imageId) {
this.imageId = imageId;
}
public String getItemName() {
return itemName;
}
public void setItemName(String itemName) {
this.itemName = itemName;
}
}
then in your activity that you would like the drawer to be implemented try
//instanciate components
private DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle mDrawerToggle;
private ListView mDrawerList;
private List<ListAdapter> drawerList = new ArrayList<ListAdapter>();
//in the onCreate method build 3 methods and organize your code
buildDrawer();
populateDrawerList();
buildListDrawer();
private void populateDrawerList() {
drawerList.add(new ListaAdapter(R.drawable.icon_1, "String 1"));
drawerList.add(new ListaAdapter(R.drawable.icon_2, "String 2"));
}
private void buildDrawer() {
mDrawerLayout = (DrawerLayout)findViewById(R.id.your_drawer_layout);
mDrawerToggle = new ActionBarDrawerToggle(YourActivity.this, mDrawerLayout, R.drawable.your_drawer_icon, "Open", "Closed"){
#Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
getActionBar().setTitle("Drawer Opened");
invalidateOptionsMenu();
}
#Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
getActionBar().setTitle("Drawer Closed");
invalidateOptionsMenu();
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
}
private void buildListDrawer() {
mDrawerList = (ListView)findViewById(R.id.listViewDrawer);
ArrayAdapter<ListAdapter> adapter = new MyDrawerArrayAdapter();
mDrawerList.setAdapter(adapter);
mDrawerList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Toast.makeText(MyActivity.this, "You have chosen " + drawerList.get(position).getItemName(), Toast.LENGTH_SHORT).show();
}
});
}
and then your modified Adapter that extends ArrayAdapter:
private class MyDrawerArrayAdapter extends ArrayAdapter<ListAdapter> {
public MyDrawerArrayAdapter() {
super(MyActivity.this, R.layout.drawer_list_item_layout, drawerList);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View drawerView = convertView;
if(drawerView == null){
drawerView = getLayoutInflater().inflate(R.layout.drawer_list_item_layout, parent, false);
}
ListAdapter currentPosition = drawerList.get(position);
ImageView drawerImage = (ImageView)drawerView.findViewById(R.id.your_drawerImage);
drawerImage.setImageResource(currentPosition.getImageId());
TextView drawerText = (TextView)drawerView.findViewById(R.id.your_drawerText);
drawerText.setText(currentPosition.getItemName());
return drawerView;
}
}

Step 01 -
Have your res/drawable folder ready with appropriate icons.
Step 02 -
In your values/string.xml add below
<string-array name="mydrawerList">
<item>item 1</item>
<item>item 2</item>
<item>item 3</item>
</string-array>
<array name="mydrawerList_icons">
<item>#drawable/ic_for_item1</item>
<item>#drawable/ic_for_item2</item>
<item>#drawable/ic_for_item3</item>
</array>
make sure you have icons in the "mydrawerList_icons" ordered as "mydrawerList" order.
Step 03 -
in your NavigationDrawerFragment.java add below lines
private String[] listTitles;
private TypedArray listIcons;
in onCreate()
listTitles = getResources().getStringArray(R.array.mydrawerList);
listIcons = getResources().obtainTypedArray(R.array.mydrawerList_icons);
Step 04 -
instead of this
mDrawerListView.setAdapter(new ArrayAdapter<String>(
getActionBar().getThemedContext(),
android.R.layout.simple_list_item_activated_1,
android.R.id.text1,
new String[]{
getString(R.string.title_section1),
getString(R.string.title_section2),
getString(R.string.title_section3),
getString(R.string.title_section4),
getString(R.string.title_section5),
getString(R.string.title_section6),
}));
type this
mDrawerListView.setAdapter(new ArrayAdapter<String>(
getActionBar().getThemedContext(),
android.R.layout.simple_list_item_activated_1,
android.R.id.text1,
listTitles)
{
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = super.getView(position, convertView, parent);
int resourceId = listIcons.getResourceId(position, 0);
Drawable drawable = getResources().getDrawable(resourceId);
((TextView) v).setCompoundDrawablesWithIntrinsicBounds(drawable, null, null, null);
return v;
}
});
Let me know the output.

Android Navigation Drawer custom ListView not responding to Click

I'm using this tutorial to add sliding menu to my app:
http://www.tutorialsbuzz.com/2014/03/android-sliding-menu-navigation-drawer.html
I went completely as said in the tutorial but it doesn't respond to the click events,
(I put log.d in the onClickListener and see that it even not go inside the on clickListener)
(it shows the list icon and title perfectly(i don't get any error, exception,..) but i could't debug why it doesn't invoke the onClickListener..)
Thanks for your help in advance
