I have tried 'dependencies' cannot be applied to '(groovy.lang.Closure)' and have tried to clean and then rebuild the project.

In your DrawerLayout Add Drawer Id:
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"

xmlns:app="http://schemas.android.com/apk/res-auto"

Custom Drawer Layout for Slide Over Action Bar

My requirement is i need the functionality of Navigation Drawer (Navigation Menu should appear both by clicking on the toggle icon and also dragging from margin) + Drawer layout on top of the action bar.
Check this post, i want the similar action.
I had gone through many post regarding this in SO itself, most of them saying to use a third-party library to use to get this done. But i don't want to use, instead in One SO question CommonsWare said like this can be done by tweaking the Drawerlayout.
How to achieve this?
Note: I don't want to use external library as it was creating problems.

In Android Default you cannot move the DrawerLayout along with the Action Bar. However if your are keen on using the Default Navigation Drawer. Hide the Action bar and create a Top layout similar to action bar. It will move with the drawerLayout. If you want further help code wise let me know.

And another important part Please change your application theme to noActionbar. Let me know if this satisfies your requirements.

Have you checked the Navigation Drawer documentation already? You have to provide a layout for the navigation drawer anyways, so it's always custom and up to you how it looks like.

Android Navigation Drawer not being closed by dragging it

I'm trying to implement a Navigation Drawer and I managed successfully to integrate it with the Action Bar: it opens and closes when the application button is pressed and it closes when I press on a blank part of the screen, but it does not allow to be dragged back to its original position. Once opened, I can't close it with a swipe (as in every application I have seen so far).
Here is my Java code:
package com.example.notificationswhisperer;
import java.util.ArrayList;
import java.util.List;
import android.app.Activity;
import android.content.res.Configuration;

import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ListView;
public class MainActivity
extends Activity {
private DrawerLayout drawerLayout;
private ListView drawerList;
private ActionBarDrawerToggle drawerToggle;
private List<AppDrawerItem> drawerItems;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_notifications_whisperer);
drawerItems = new ArrayList<AppDrawerItem>();
drawerItems.add(
new AppDrawerItem("Settings",
getResources().getDrawable(R.drawable.ic_action_settings)));
drawerItems.add(
new AppDrawerItem("Test",
getResources().getDrawable(R.drawable.ic_action_settings)));
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
drawerLayout = (DrawerLayout) findViewById(R.id.layout_app_drawer);
drawerToggle = new ActionBarDrawerToggle(
this, // Context
drawerLayout, // DrawerLayout object
R.drawable.ic_drawer, // Drawer icon
0, // Open Drawer description
0) { // Closed Drawer description
public void onDrawerOpened(View view) {
super.onDrawerOpened(view);
invalidateOptionsMenu();
}
public void onDrawerSlide(View view, float offset) {
if (offset > .5) {
onDrawerOpened(view);
} else {
onDrawerClosed(view);
}
}
public void onDrawerClosed(View view) {
super.onDrawerClosed(view);
invalidateOptionsMenu();
}
};
drawerLayout.setDrawerListener(drawerToggle);
drawerLayout.setDrawerShadow(R.drawable.drawer_shadow, Gravity.START);
drawerList = (ListView) findViewById(R.id.list_app_drawer);
drawerList.setAdapter(new AppDrawerAdapter(this, drawerItems));
drawerList.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
drawerList.setItemChecked(position, true);
drawerLayout.closeDrawer(drawerList);
}
});
}

</RelativeLayout>
Am I missing something? Thank you in advance.
ADDENDUM: Additionally, the back button won't close the Drawer.

I had the very same issue : the drawer could be opened by a swipe, but could only be closed by a click on the actionbar button.
After some research, it appeared that the underlying activity had several critical bugs : some fragments were added which were adding an un-initialized pager (with a null adapter)
Anyway, when I fixed these bugs (which had nothing to do with the drawer implementation), then behavior went correct.

Using getFragmentManager on a ListActivity

I just want to know if this is possible since first. I have created a custom listView based on the tutorial I read from Sai Geetha. Well it works perfectly on my app except that it needs to extend ListActivity instead of FragmentActivity. Now I'm having a hard time configuring and adding a dialog for this since I need to apply a fragment dialog and I can't use the getFragmentManager() since I'm not working with the FragmentActivity. Is there's another way I can do to work on this without sacrificing the ListActivity? Thanks!
Here's my code so far
XML:
conversation_list_view

You can use ListFragment inside FragmentActivity instead of using a ListActivity.
