If i delete XML code which is inside DrawerLayout, then it works fine.

you forgot to add drawerLayout.addDrawerListener(toggle); before toggle.syncState();

I had the same problem and i found the question in another thread:
final SwipeRefreshLayout swipeLayout =
(SwipeRefreshLayout)this.findViewById(R.id.swipeToRefresh);
swipeLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
#Override
public void onRefresh() {
myWebView.reload(); // refreshes the WebView
if (null != swipeLayout) {
swipeLayout.setRefreshing(false);
}
}
});

Navigation drawer implementation with activities using inheritance

In my app I have to use navigation drawer with all activities. So I have created a base activity called DrawerActivity. I wrote the code for navigation drawer in DrawerActivity and then extended the UserDashBoardActivity from DrawerActivity.
The problem is that DrawerActivity properties aren't executed in UserDashBoardActivity. I can't interact with DrawerActivity in UserDashBoardActivity. Here that drawer menu is in ActionBar in all the activities.
This is my DrawerActivity
public class DrawerActivity extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.drawer_list_view);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.left_drawer);
mDrawerItems = getResources().getStringArray(R.array.navigation_drawer_items_array);
//mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
mDrawerList.setAdapter(new ArrayAdapter<String>(
this, R.layout.drawer_list_items, mDrawerItems));
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
mDrawerToggle = new ActionBarDrawerToggle(this,
mDrawerLayout, R.drawable.ic_menu,
R.string.drawer_open, R.string.drawer_close) {
public void onDrawerOpened(View view) {
invalidateOptionsMenu();
}
public void onDrawerClosed(View view) {
invalidateOptionsMenu();
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
mDrawerToggle.syncState();
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
mDrawerToggle.onConfigurationChanged(newConfig);
}
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
boolean drawerOpen = mDrawerLayout.isDrawerOpen(mDrawerList);
for (int index = 0; index < menu.size(); index++) {
MenuItem menuItem = menu.getItem(index);
if (menuItem != null) {
// hide the menu items if the drawer is open
menuItem.setVisible(!drawerOpen);
}
}
return super.onPrepareOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
private class DrawerItemClickListener implements ListView.OnItemClickListener {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int position, long id) {
switch (position) {
case 0: {
Intent intent = new Intent(DrawerActivity.this, UserDashBoardActivity.class);
startActivity(intent);
break;
}
case 1: {
Intent intent = new Intent(DrawerActivity.this, AdmissionActivity.class);
startActivity(intent);
break;
}
default:
break;
}
mDrawerLayout.closeDrawer(mDrawerList);
}
}
This is my UseDashBoardActivity

notificationBtn = (ImageButton) findViewById(R.id.notification_btn);
logoutBtn = (ImageButton) findViewById((R.id.logout_btn));
final EditText Search = (EditText)findViewById(R.id.emailAddress);
mDrawerList = (ListView)findViewById(R.id.drawer_layout);
searchBtn.setOnClickListener(new View.OnClickListener() {
#Override

Intent regAct = new Intent(getApplicationContext(), SearchActivity.class);
// Clears History of Activity
regAct.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

});
favBtn.setOnClickListener(new View.OnClickListener(){

The UserDashboard activity is executed as it is but I need the property of DrawerActivity to be executed along with this activity. How to do it?

Let the parent Activity add the required ViewGroup as child of the FrameLayout. To achieve this, use the following method for DrawerActivity:
protected void addToContentView(int layoutResID)
{
// as part of onCreate() we had already
// setContentView(R.layout.activity_drawer);
if (layoutResID >= 0)
{
Toast.makeText(this, "activity content found", Toast.LENGTH_LONG).show();
FrameLayout fl = (FrameLayout)findViewById(R.id.activity_frame);
View.inflate(this, layoutResID, fl);
}
else
{
Toast.makeText(this, "activity content missing", Toast.LENGTH_LONG).show();
}
}
Then, in the onCreate() method of the child Activity:
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
// call this instead of setContentView()
addToContentView(R.layout.activity_user_dashboard);
// put here your code as before...
}

Drawer's layout:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
/>
<!--you need to add everything to this frameLayout then only you will be able to access Navigation DrawerLayout-->
<FrameLayout
android:id="#+id/fragment"
android:layout_width="match_parent"
android:layout_height="match_parent"></FrameLayout>
</LinearLayout>
<ListView
android:id="#+id/navigation_list"
android:layout_width="320dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
android:fitsSystemWindows="true"
android:background="#color/white"
/>
</android.support.v4.widget.DrawerLayout>
The Activity with Drawer:(Only important code is shown)
public abstract class BaseDrawerLayoutActivity extends AppCompatActivity implements OnItemClickListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.base_drawer_layout_activity);
//rest of the things
//NOTE: loadNavMenu is abstract so that you can implement it in other activities as per you need, otherwise remove this and load it here itself
loadNavMenu();
}
protected abstract void loadNavMenu();
// call this method whenever you enter new activity and load the fragment here.
public void showFragment(Fragment object, String title) {
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.fragment, object);
transaction.commit();
}}
Those activities which need the drawer menu can inherit above class. Not inflate all the layout's inside FrameLayout only.
public class MainActivity extends BaseDrawerLayoutActivity {
public static final String TAG = OLMSActivity.class.getSimpleName();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//the method below will call the BaseDrawerLayoutActivity method and change the fragment for you to see.
showFragment(new MyProfileFragment(), "My Profile");
}
#Override
protected void loadNavMenu() {
NavItems.clear();
//load your menu items
}
private void loadNavFavourites(){
//todo
}}
MyProfileFragment is just a class with fragment and this one call inflate a layout in its OnCreateView method.

navigation drawer doesn't opened

In my app i am extending the drawerActivity which is having the properties of navigation drawer. The problem is that menu icon appears at the action bar. When i click the action bar nothing happends. Here i have posted the ode for your reference

The Adapter that you are setting is wrong you are using an ArrayAdapter but you should be actually using an ActionBarDrawerToggle like this
private void initDrawer() {
ActionBarDrawerToggle drawerToggle = new ActionBarDrawerToggle(this, drawerLayout, toolbar, R.string.drawer_open, R.string.drawer_close) {
#Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
}
#Override
public void onDrawerOpened(View drawerView) {
}
};
drawerLayout.setDrawerListener(drawerToggle);
}
if you need furthur assistance refer this link http://developer.android.com/training/implementing-navigation/nav-drawer.html

You need to add listview in navigation drawer like below.
<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/activity_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</FrameLayout>
<!-- The navigation drawer -->
<android.support.design.widget.NavigationView
 android:id="#+id/navigation"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start" >
<ListView android:id="#+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#111"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp" />
</android.support.design.widget.NavigationView>
</android.support.v4.widget.DrawerLayout>

In your drawer activity (DrawerActivity.class)
public class DrawerActivity extends ActionBarActivity
Replace the actionbaractivity with appcompactability. I think this should solve your problem.

navigation drawer not opening for webview button click

I am trying to open a nav drawer when user clicks on a webview (HTML) button. I have a code which works fine when I use Android button but it does not work when I use HTML button. The navigation drawer shows when you drag it from left side but not when you click the HTML button.

Does showDialog method get called? If it is so, try to call drawerLayout.openDrawer from UI thread: MainActivity.this.runOnUiThread(...)
