android navigation Drawer button not working

In my android application I am using "navigation drawer"..
I have "BaseActivity.java"
public class BaseActivity extends Activity {
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
protected RelativeLayout _completeLayout, _activityLayout;
// nav drawer title
private CharSequence mDrawerTitle;
// used to store app title
private CharSequence mTitle;
private ArrayList<NavDrawerItem> navDrawerItems;
private NavDrawerListAdapter adapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.drawer);
// displayView(0);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.left_drawer);
}
public void set(String[] navMenuTitles, TypedArray navMenuIcons) {
mTitle = mDrawerTitle = getTitle();
navDrawerItems = new ArrayList<NavDrawerItem>();
// adding nav drawer items
if (navMenuIcons == null) {
for (int i = 0; i < navMenuTitles.length; i++) {
navDrawerItems.add(new NavDrawerItem(navMenuTitles[i]));
}
} else {
for (int i = 0; i < navMenuTitles.length; i++) {
navDrawerItems.add(new NavDrawerItem(navMenuTitles[i],
navMenuIcons.getResourceId(i, -1)));
}
}
getActionBar().setDisplayHomeAsUpEnabled(true);
adapter = new NavDrawerListAdapter(getApplicationContext(), navDrawerItems);
mDrawerList.setAdapter(adapter);
mDrawerList.setOnItemClickListener(new SlideMenuClickListener());
// setting the nav drawer list adapter
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
R.drawable.ic_drawer, // nav menu toggle icon
R.string.app_name, // nav drawer open - description for
// accessibility
R.string.app_name // nav drawer close - description for
// accessibility
) {
public void onDrawerClosed(View view) {
getActionBar().setTitle(mTitle);
// calling onPrepareOptionsMenu() to show action bar icons
invalidateOptionsMenu();
}
public void onDrawerOpened(View drawerView) {
getActionBar().setTitle(mDrawerTitle);
// calling onPrepareOptionsMenu() to hide action bar icons
invalidateOptionsMenu();
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
}
private class SlideMenuClickListener implements
ListView.OnItemClickListener {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
// display view for selected nav drawer item
displayView(position);
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// getSupportMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item.getItemId() == android.R.id.home) {
if (mDrawerLayout.isDrawerOpen(mDrawerList)) {
mDrawerLayout.closeDrawer(mDrawerList);
} else {
mDrawerLayout.openDrawer(mDrawerList);
}
}
return super.onOptionsItemSelected(item);
}
/***
* Called when invalidateOptionsMenu() is triggered
*/
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
// if nav drawer is opened, hide the action items
// boolean drawerOpen = mDrawerLayout.isDrawerOpen(mDrawerList);
// menu.findItem(R.id.action_settings).setVisible(!drawerOpen);
return super.onPrepareOptionsMenu(menu);
}
/**
* Diplaying fragment view for selected nav drawer list item
* */
private void displayView(int position) {
switch (position) {
case 0:
Intent intent = new Intent(this, FirstActivity.class);
startActivity(intent);
finish();// finishes the current activity
break;
case 1:
Intent intent1 = new Intent(this, SecondActivity.class);
startActivity(intent1);
finish();// finishes the current activity
break;
default:
break;
}
// update selected item and title, then close the drawer
mDrawerList.setItemChecked(position, true);
mDrawerList.setSelection(position);
mDrawerLayout.closeDrawer(mDrawerList);
}
#Override
public void setTitle(CharSequence title) {
mTitle = title;
getActionBar().setTitle(mTitle);
}
/**
* When using the ActionBarDrawerToggle, you must call it during
* onPostCreate() and onConfigurationChanged()...
*/
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
// Sync the toggle state after onRestoreInstanceState has occurred.
mDrawerToggle.syncState();
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
// Pass any configuration change to the drawer toggls
mDrawerToggle.onConfigurationChanged(newConfig);
}
}
and my "FirstActivity.java" is:--
FirstActivity extends BaseActivity {
private String[] navMenuTitles;
private TypedArray navMenuIcons;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_test);
navMenuTitles = getResources().getStringArray(R.array.nav_drawer_items);
navMenuIcons = getResources().obtainTypedArray(R.array.nav_drawer_icons);
set(navMenuTitles, navMenuIcons);
}
}
and the SecondActivity.java is same as "FirstActivity.java"..
But when I run the application, It only showing FirstActivity..and navigation button(drawer) is not working.no any error is also occuring..can anyone tell me where is the problem????

Opening Activity from Navigation Drawer

Every time I open my Activity from Navigation Drawer, a blank screen appears. I am trying to open a fragment from my Navigation:
public class MainActivity extends ActionBarActivity {
private ListView mDrawerList;
private DrawerLayout mDrawerLayout;
private ArrayAdapter<String> mAdapter;
private ActionBarDrawerToggle mDrawerToggle;
private String mActivityTitle;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mDrawerList = (ListView)findViewById(R.id.navList);mDrawerLayout = (DrawerLayout)findViewById(R.id.drawer_layout);
mActivityTitle = getTitle().toString();
addDrawerItems();
setupDrawer();
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
}
private void addDrawerItems() {
String[] osArray = {"Math", "Physics", "Chemistry"};
mAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, osArray);
mDrawerList.setAdapter(mAdapter);
mDrawerList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
switch(position) {
case 0:
Intent a = new Intent(MainActivity.this, MathActivity.class);
startActivity(a);
break;
case 1:
Intent b = new Intent(MainActivity.this, PhysicsActivity.class);
startActivity(b);
break;
case 2:
Intent c = new Intent(MainActivity.this, ChemistryActivity.class );
startActivity(c);
break;
default:
}
}
});
}
private void setupDrawer() {
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.string.drawer_open, R.string.drawer_close) {
/** Called when a drawer has settled in a completely open state. */
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
getSupportActionBar().setTitle("Navigation!");
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
/** Called when a drawer has settled in a completely closed state. */
public void onDrawerClosed(View view) {
super.onDrawerClosed(view);
getSupportActionBar().setTitle(mActivityTitle);
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
};
mDrawerToggle.setDrawerIndicatorEnabled(true);
mDrawerLayout.setDrawerListener(mDrawerToggle);
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
// Sync the toggle state after onRestoreInstanceState has occurred.
mDrawerToggle.syncState();
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
mDrawerToggle.onConfigurationChanged(newConfig);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
// Activate the navigation drawer toggle
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
To open Activity like this:
public class MathActivity extends Activity{
protected void onCreate(Bundle bundle) {
setContentView(R.layout.math_fragment_activity);
super.onCreate(bundle);
}
}
Every time I do so, a blank screen appears. Why is this happening and can anyone help me solve this problem?
UPDATE:
Here is my layout file:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ListView
android:id="#+id/listViewAnimals"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:dividerHeight="0.1dp"
android:divider="#0000CC"/> </RelativeLayout>

Try switching your setContentiew to be after the super.onCreate call.

Android: Navigation-Drawer on all activities

I want to add navigation drawer on all actvities of my Android project. This is the code of the MainActivity:
public class MainActivity extends Activity {
private String[] drawerListViewItems;
private DrawerLayout drawerLayout;
private ListView drawerListView;
private ActionBarDrawerToggle actionBarDrawerToggle;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// get list items from strings.xml
drawerListViewItems = getResources().getStringArray(R.array.items);
// get ListView defined in activity_main.xml
drawerListView = (ListView) findViewById(R.id.left_drawer);
// Set the adapter for the list view
drawerListView.setAdapter(new ArrayAdapter<String>(this,
R.layout.drawer_listview_item, drawerListViewItems));
// App Icon
drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
//drawerLayout = (DrawerLayout) findViewById(R.drawable.ic_drawer_2);
actionBarDrawerToggle = new ActionBarDrawerToggle(
this, /* host Activity */
drawerLayout, /* DrawerLayout object */
R.drawable.ic_drawer, /* nav drawer icon to replace 'Up' caret */
R.string.drawer_open, /* "open drawer" description */
R.string.drawer_close /* "close drawer" description */
);
// Set actionBarDrawerToggle as the DrawerListener
drawerLayout.setDrawerListener(actionBarDrawerToggle);
getActionBar().setDisplayHomeAsUpEnabled(true);
// just styling option add shadow the right edge of the drawer
drawerLayout.setDrawerShadow(R.drawable.ic_drawer, GravityCompat.START);
drawerListView.setOnItemClickListener(new DrawerItemClickListener());
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
// Sync the toggle state after onRestoreInstanceState has occurred.
actionBarDrawerToggle.syncState();
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
actionBarDrawerToggle.onConfigurationChanged(newConfig);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// call ActionBarDrawerToggle.onOptionsItemSelected(), if it returns true
// then it has handled the app icon touch event
if (actionBarDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
private class DrawerItemClickListener implements ListView.OnItemClickListener {
#Override
public void onItemClick(AdapterView parent, View view, int position, long id) {
displayView(position);
drawerLayout.closeDrawer(drawerListView);
}
private void displayView(int position)
{
switch (position)
{
case 0:
secondactivity();
break;
case 1:
Toast.makeText(MainActivity.this, "2", Toast.LENGTH_LONG).show();
break;
case 2:
Toast.makeText(MainActivity.this, "3", Toast.LENGTH_LONG).show();
default:
break;
}
}
}
public void secondactivity (){
Intent cambioActivity;
cambioActivity = new Intent (this, SecondActivity.class);
startActivity(cambioActivity);
}
}
In this code I create the navigation drawer, I want the navigation drawer on all activities, so my Second Activity's code is this:
public class SecondActivity extends MainActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_secondactivity);
}
The navigation drawer is on the first activity but there isn't on other activities, why? Can someone help me?

The easy way is that you should create fragments. If you are ready to for little hard thing then this is for you. It will let you have same navigation drawer in all activities.
Create drawer_n_activity.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<FrameLayout
android:id="#+id/drawer_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<YourDrawer
android:id="#+id/drawer_drawer"
android:layout_width="match_parent"
android:layout_height="fill_parent" >
</YourDrawer>
</RelativeLayout>
Your DrawerActivity.class
public class DrawerActivity extends Activity {
public RelativeLayout fullLayout;
public FrameLayout frameLayout;
#Override
public void setContentView(int layoutResID) {
fullLayout = (RelativeLayout) getLayoutInflater().inflate(R.layout.drawer_n_activity, null);
frameLayout = (FrameLayout) fullLayout.findViewById(R.id.drawer_frame);
getLayoutInflater().inflate(layoutResID, frameLayout, true);
super.setContentView(fullLayout);
//Your drawer content...
}
}
Now, to include same Navigation Drawer in all your activities and mind one more thing, all your activities must extend DrawerActivity
public class MainActivity extends DrawerActivity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main); //layout for 1st activity
}
}
public class SecondActivity extends DrawerActivity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.second_activity); //layout for 2nd activity
}
}

Okay Guys will share my way I do it (in case you are developing project after somebody and there is already tons of activities).
Finally I inflate navigation drawer with one line of code (in onCreate):
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mContext = this; //context
//setContentView(R.layout.activity_favorites); // Was so
Utils.inflatedNavigationDrawerView(mContext, R.layout.activity_favorites); // Now is
//...
}
next what is Utils? :
public class Utils{
public static void inflatedNavigationDrawerView(Context context, int layoutId){
// Here get view of clear DrawerLayout
final View drawerLayout = View.inflate(context,R.layout.navigation_drawer_inflator, null);
// Next inflate to it passed layout for activity
final View mainLayout = View.inflate(context,layoutId, (ViewGroup) drawerLayout);
// And finally inflate to it fragment for NavigationDraver
final View fragmentLayout = View.inflate(context,R.layout.navigation_drawer_inflator_fragment, (ViewGroup) drawerLayout);
// Next we should try to get our drawer (should check with casting to each activity you want to insert to)
NavigationDrawerFragment drawerFragment = null;
// this block should be repeated for each activity you want to use in.
if (context instanceof FavoritesActivity){
// Set our pack of inflates to contentview
((FavoritesActivity) context).setContentView(mainLayout);
// And now we get NavigationDrawerFragment
drawerFragment = (NavigationDrawerFragment)
((FavoritesActivity) context).getSupportFragmentManager().findFragmentById(R.id.navigation_drawer_fragment);
}
if(drawerFragment != null){ // if null then we missed some castings for activity used in.
// Finally setup our drawer
drawerFragment.setUpEasy(R.id.navigation_drawer_fragment, (DrawerLayout)drawerLayout.findViewById(R.id.drawer_layout), (Toolbar) mainLayout.findViewById(R.id.app_bar));
}
}
}
If you would like to avoid creation of hamburger in Toolbar then you shoud in setUpEasy place: mDrawerToggle.setDrawerIndicatorEnabled(false);
Here is my sample of setup:
public void setUpEasy(int fragmentId, DrawerLayout drawerLayout, Toolbar toolBar) {
mContainerView = getActivity().findViewById(fragmentId);
mDrawerLayout = drawerLayout;
mDrawerToggle = new ActionBarDrawerToggle(getActivity(), drawerLayout, toolBar, R.string.open, R.string.close){
#Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
if(!mUserLearnedDrawer){
mUserLearnedDrawer = true;
saveToPreferences(getActivity(), Constants.PREFERENCES_LEARNDRAWER_KEY, mUserLearnedDrawer+"");
}
}
#Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
}
};
mDrawerToggle.setDrawerIndicatorEnabled(false); // If false then no hamburger menu.
mDrawerLayout.setDrawerListener(mDrawerToggle);
mDrawerLayout.post(new Runnable() {
#Override
public void run() {
mDrawerToggle.syncState();
}
});
}
and views used:
// navigation_drawer_inflator.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:dragAndDrop="http://schemas.android.com/apk/res-auto"
android:id="#+id/drawer_layout"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
</android.support.v4.widget.DrawerLayout>
// navigation_drawer_inflator_fragment.xml
<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/navigation_drawer_fragment"
android:layout_width="#dimen/navigation_drawer_width"
android:layout_height="match_parent"
android:layout_gravity="start"
android:layout_marginTop="56dp"
app:layout="#layout/fragment_navigation_drawer"
tools:layout="#layout/fragment_navigation_drawer" />
Finally if you will implement this - You will be able to insert navigation drawer to any activity on run. Cheers :)

Here's how I did it. Create the helper class. I also added some optional code for the ability to finish() the class.
public class NavDrawerHelper extends ContextWrapper{
public NavDrawerHelper(Context context){
super(context);
}
public void initNav(final DrawerLayout drawerLayout, NavigationView navigationView, Toolbar toolbar, final boolean isFinish){
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem menuItem) {
int id = menuItem.getItemId();
switch (id){
case R.id.nav_home:
startActivity(new Intent(getBaseContext(), MainActivity.class));
if (isFinish) ((Activity)getBaseContext()).finish();
drawerLayout.closeDrawers();
break;
case R.id.nav_settings:
startActivity(new Intent(getBaseContext(), SettingsActivity.class));
if (isFinish) ((Activity)getBaseContext()).finish();
drawerLayout.closeDrawers();
break;
}
return true;
}
});
ActionBarDrawerToggle actionBarDrawerToggle = new ActionBarDrawerToggle(((Activity)getBaseContext()),drawerLayout,toolbar,R.string.drawer_open,R.string.drawer_close){
#Override
public void onDrawerClosed(View v){
super.onDrawerClosed(v);
}
#Override
public void onDrawerOpened(View v) {
super.onDrawerOpened(v);
}
};
drawerLayout.addDrawerListener(actionBarDrawerToggle);
actionBarDrawerToggle.syncState();
}
}
then add this code to all activities. This replaces your existing initNavigationDrawer() method.
public void initNavigationDrawer() {
//views
NavigationView navigationView = findViewById(R.id.navigation_view);
DrawerLayout drawerLayout = findViewById(R.id.drawer);
NavDrawerHelper navDrawerHelper = new NavDrawerHelper(this);
navDrawerHelper.initNav(drawerLayout, navigationView, toolbar, false);
}

Fragment not showing icon

I'm having trouble with an android app, mainly because when I load a fragment into the activity it never shows the icon in the app (it shows the 3 dots as if there's no space for the icon to show and it displays the text instead).
My activity is using a navigation drawer I don't know if it has to do with the problem, I've read several answers with the same problem but none of the solutions seem to affect the behaviour.
If I add the icon programatically it shows fine, but whenever I try to use the XML it never shows the icon as action.
I'm targeting minSDK = 14 and targetSDK = 19
Here's my main activity
public class MainActivity extends Activity {
/**
* Fragment managing the behaviors, interactions and presentation of the navigation drawer.
*/
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
List<DrawerItem> dataList;
CustomDrawerAdapter adapter;
/**

*/
private CharSequence mTitle;
private CharSequence mDrawerTitle;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
dataList = new ArrayList<>();
mTitle = mDrawerTitle = getTitle();
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);

}
/** Called when a drawer has settled in a completely open state. */
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
getActionBar().setTitle(mDrawerTitle);
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
mDrawerList = (ListView) findViewById(R.id.lvNavigationDrawer);

mDrawerList.setAdapter(adapter);
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
//mDrawerList.setAdapter(new ArrayAdapter<>(this,R.layout.drawer_list_item,mMenuTitles));
}
private class DrawerItemClickListener implements ListView.OnItemClickListener {

</menu>

You are using the native action bar, not the appcompat-v7 backport, as evidenced by your inheriting from Activity and calling getActionBar(). Hence, remove the app namespace from your menu resource and change your app:showAsAction to android:showAsAction.

How to start a new activity from item click in NavDrawer

I'm a novice. I was just wondering how to start a new (pre-defined) activity from clicking one of the option items inside a navigation drawer? I have just completed a tutorial on how to make the NavDrawer. Here is what I have so far in my main activity (it's called IntroActivity)
IntroActivity.java:
public class IntroActivity extends Activity {
private String[] drawerListViewItems;
private ListView drawerListView;
private DrawerLayout drawerLayout;
private ActionBarDrawerToggle actionBarDrawerToggle;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_intro);
//Retrieve List items from strings.xml
drawerListViewItems = getResources().getStringArray(R.array.list_items);
//Retrieve ListView defined in intro_activity.xml
drawerListView = (ListView) findViewById(R.id.left_drawer);
//Set the adapter for the list view
drawerListView.setAdapter(new ArrayAdapter<String>(this, R.layout.drawer_listview_item, drawerListViewItems));
//App Icon
drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
actionBarDrawerToggle = new ActionBarDrawerToggle(
this, /* Host Activity */
drawerLayout, /* DrawerLayout object */
R.drawable.ic_drawer, /* Image to replace "up" image*/
R.string.drawer_open, /* Open drawer description*/
R.string.drawer_close /* Close drawer description*/
);
//Set actionBarDrawerToggle as the DrawerListener
drawerLayout.setDrawerListener(actionBarDrawerToggle);
getActionBar().setDisplayHomeAsUpEnabled(true);
//ADD SHADOW TO THE RIGHT EDGE OF DRAWER
drawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
//Responding to clicks implementation:
drawerListView.setOnItemClickListener(new DrawerItemClickListener());
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
//Sync the toggle state after onRestart... has occurred
actionBarDrawerToggle.syncState();
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
actionBarDrawerToggle.onConfigurationChanged(newConfig);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.intro, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
//Call ActionBarDrawerToggle.onOptionsItemSelected(),
//If it returns true, then it has handles the app icon touch event
if (actionBarDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
private class DrawerItemClickListener implements ListView.OnItemClickListener {
#Override
public void onItemClick(AdapterView parent, View view, int position,
long id) {
//I WOULD LIKE TO REPLACE THE FOLLOWING CODE WITH SOMETHING
//THAT CAN START A NEW ACTIVITY
/*Toast.makeText(IntroActivity.this, ((TextView)view).getText(),
Toast.LENGTH_LONG).show(); */
drawerLayout.closeDrawer(drawerListView);
}
}
}
Thanks if you can help.

Use this
Intent intent = new Intent(IntroActivity.this, YourNewActivity.class);
startActivity(intent);
where YourNewActivity is the activity you want to start
