How do I update unread notification counter in the Navigation Drawer?

I am currently working on app which will have a notification drawer with 2 sections -
A dashboard of status requests (pending, submitted, in process, completed). I have named it DashboardFragment.java
A notification center which shows all messages received from the 3rd party Java server(via Google Cloud Messaging server). I have named it PushMessagesFragment.java
The problem that I am facing is that when I receive notifications from the server, the "unread messages" count is not reset to zero once I open the PushMessages Fragment.
Also, the unread message count is ONLY updated when I click on the notification; whereas it should update (and show me the count of number of unread messages) even if I simply open the navigation drawer.
Here is a screenshot -

For the Navigation Drawer, I am using a Model Class named NavDrawerItem.java which has the following code -
public class NavDrawerItem {
private String title;
private int icon;
private String count = "0";
// boolean to set visiblity of the counter
private boolean isCounterVisible = false;
public NavDrawerItem(String title, int icon) {
this.title = title;
this.icon = icon;
}
public NavDrawerItem(String title, int icon, boolean isCounterVisible, String count) {
this.title = title;
this.icon = icon;
this.isCounterVisible = isCounterVisible;
this.count = count;
}
public String getTitle() {
return this.title;
}
public int getIcon() {
return this.icon;
}
public String getCount() {
return this.count;
}
public boolean getCounterVisibility() {
return this.isCounterVisible;
}
public void setTitle(String title) {
this.title = title;
}
public void setIcon(int icon) {
this.icon = icon;
}
public void setCount(String count) {
this.count = count;
}
public void setCounterVisibility(boolean isCounterVisible) {
this.isCounterVisible = isCounterVisible;
}
}
I am using a Custom Adapter named NavigationDrawerListAdapter for my Navigation Drawer.
public class NavigationDrawerListAdapter extends BaseAdapter {
private Context context;
private ArrayList < NavDrawerItem > navDrawerItems;
public NavigationDrawerListAdapter(Context context, ArrayList < NavDrawerItem > navDrawerItems) {
this.context = context;
this.navDrawerItems = navDrawerItems;
}#
Override
public int getCount() {
return navDrawerItems.size();
}#
Override
public Object getItem(int position) {
return navDrawerItems.get(position);
}#
Override
public long getItemId(int position) {
return position;
}#
Override
public View getView(int position, View convertView, ViewGroup parent) {
NavDrawerViewHolder viewHolder;
if (convertView == null) {
viewHolder = new NavDrawerViewHolder();
LayoutInflater mInflater = (LayoutInflater)
context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
convertView = mInflater.inflate(R.layout.nav_drawer_list_item, null);
viewHolder.imgIcon = (ImageView) convertView.findViewById(R.id.icon);
viewHolder.txtTitle = (TextView) convertView.findViewById(R.id.title);
viewHolder.txtCount = (TextView) convertView.findViewById(R.id.counter);
convertView.setTag(viewHolder);
} else {
// Get the ViewHolder back to get fast access to the TextView
// and the ImageView.
viewHolder = (NavDrawerViewHolder) convertView.getTag();
}
viewHolder.imgIcon.setImageResource(navDrawerItems.get(position).getIcon());
viewHolder.txtTitle.setText(navDrawerItems.get(position).getTitle());
// displaying count
// check whether it set visible or not
if (navDrawerItems.get(position).getCounterVisibility()) {
viewHolder.txtCount.setText(navDrawerItems.get(position).getCount());
} else {
// hide the counter view
viewHolder.txtCount.setVisibility(View.GONE);
}
return convertView;
}
static class NavDrawerViewHolder {
ImageView imgIcon;
TextView txtTitle;
TextView txtCount;
}
}

return result;
}
#Override
protected void onPostExecute(String result) {
//Toast.makeText(getApplicationContext(), result,Toast.LENGTH_LONG).show();
}
}
}

Finally, I've managed to get the result I wanted.
First, I changed the setText() value in NavigationDrawerListAdapter.
if (navDrawerItems.get(position).getCounterVisibility()) {
//viewHolder.txtCount.setText(navDrawerItems.get(position).getCount());
//The next line is where I made the change
viewHolder.txtCount.setText(String.valueOf(NotificationID.getID()));
Log.e("Counter Value set to", String.valueOf(NotificationID.getID()));
}
Then, in my Singleton class NotificationID, I changed the setZero() method body from
public static int setToZero()
{
return 0;
}
to
public static int setToZero()
{
c = 0;
return c;
}
The final change I made was in PushMessagesFragment.java since I wanted to reset the counter to zero whenever I opened that fragment.
//set notification id to zero
NOTIFICATION_ID = NotificationID.setToZero();
//NOTIFICATION_ID = NotificationID.setID();
Log.e("Push Messages NOTIFICATION_ID", String.valueOf(NotificationID.getID()));
Now my app seems to be working fine, showing actual notification count when I receive messages, and showing ZERO count when I open PushMessage Fragment.

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.

Shift above code from fragment to your MAinActivity.java

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
