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

}
return super.onOptionsItemSelected(item);
}

// menu.findItem(R.id.action_settings).setVisible(!drawerOpen);
return super.onPrepareOptionsMenu(menu);
}
/**

* */
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????

Icon to Navigation Drawer

I am trying to add icons to my Navigation Drawer in Android. I have the following code in my main
public class MainActivity extends ActionBarActivity {
private ListView mDrawerList;
private DrawerLayout mDrawerLayout;
private ArrayAdapter<String> mAdapter;
private ActionBarDrawerToggle mDrawerToggle;
private String mActivityTitle;
private myAdapter MyAdapter;

}
private void addDrawerItems() {
String[] osArray = {"Math", "Physics", "Chemistry"};
MyAdapter = new myAdapter(this);
mDrawerList.setAdapter(MyAdapter);
mDrawerList.setOnItemClickListener(new AdapterView.OnItemClickListener() {

android:id="#+id/imageViewRow1"
/>
<TextView
android:layout_margin="8dp"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="Large Text"
android:id="#+id/textViewRow1"
/>
</LinearLayout>
I am simple just trying to add icons to the navigation drawer, but this does not work and I am not sure what goes wrong. The application just shuts down. All help is really appreciated!
Here is my log-cat:

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

Android Navigation Drawer Level

I am having some problem with navigation drawer in Android. So these are the codes with me:
public class NavigationDrawer extends FragmentActivity {
private String[] drawerListViewItems;
private DrawerLayout drawerLayout;
private ListView drawerListView;
private ActionBarDrawerToggle actionBarDrawerToggle;
protected DrawerLayout fullLayout;
protected FrameLayout actContent;
#Override
public void setContentView(final int layoutResID) {
fullLayout = (DrawerLayout) getLayoutInflater().inflate(
R.layout.navigation_drawer, null); // Your base layout here
actContent = (FrameLayout) fullLayout.findViewById(R.id.act_content);
getLayoutInflater().inflate(layoutResID, actContent, true);
super.setContentView(fullLayout);
drawerListViewItems = getResources().getStringArray(R.array.items);
drawerListView = (ListView) findViewById(R.id.left_drawer);
drawerListView.setAdapter(new ArrayAdapter<String>(this,
R.layout.drawer_listview_item, drawerListViewItems));
drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
actionBarDrawerToggle = new ActionBarDrawerToggle(this,
drawerLayout,
R.drawable.ic_drawer,
R.string.drawer_open,
R.string.drawer_close
);
drawerLayout.setDrawerListener(actionBarDrawerToggle);
getActionBar().setDisplayHomeAsUpEnabled(true);
drawerLayout.setDrawerShadow(R.drawable.drawer_shadow,
GravityCompat.START);
drawerListView.bringToFront();
drawerListView.setOnItemClickListener(new DrawerItemClickListener());
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
actionBarDrawerToggle.onConfigurationChanged(newConfig);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (actionBarDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
actionBarDrawerToggle.syncState();
}
private class DrawerItemClickListener implements
ListView.OnItemClickListener {
#Override
public void onItemClick(AdapterView parent, View view, int position,
long id) {
switch (position) {
}
drawerLayout.closeDrawer(drawerListView);
}
}
}
And my xml file:
<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" >
<ListView
android:id="#+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#111"
android:divider="#CCCCCC"
android:dividerHeight="0.5dp"
android:paddingLeft="16dp"
android:paddingRight="16dp" />
<FrameLayout
android:id="#+id/act_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
</FrameLayout>
</android.support.v4.widget.DrawerLayout>
And the string file where I declare the words for navigation drawer item:
<string-array name="items">
<item>Dashboard</item>
<item>Account</item>
<item>Setting</item>
<item>Recurring</item>
<item>Budget</item>
</string-array>
But with these code, the navigation drawer level is only one. What I am trying to do is there will be still sub item under Dashboard, Setting and Budget.
I wonder how to modify it so that the navigation drawer could take in one more level of items.
Thanks in advance.

Steps:
Change ListView to Expandablelistview.
Add subitems for the group items required.

Display logo in ActionBar

I have an action bar but have only been to display the title of application or/and the title of the current fragment activity into it. I would want to display logo in it, and any attempts to add a logo have been unsuccessful.
Below is the code:
public class MainActivity extends ActionBarActivity {
private String[] mOptionMenu;
private DrawerLayout mDrawerLayout;
private RelativeLayout mDrawerRelativeLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
private CharSequence mTitleSection;
private CharSequence mTitleApp;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ImageView button=(ImageView)findViewById(R.id.logobutton);
mOptionMenu = new String[] { "Opción 1", "Opción 2", "Opción 3" };
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerRelativeLayout = (RelativeLayout)
findViewById(R.id.left_drawer);
mDrawerList = (ListView) findViewById(R.id.list_view_drawer);
mDrawerList.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,
mOptionMenu));
mDrawerList.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Fragment fragment = null;
switch (position) {
case 0:
fragment = new FirstFragment();
break;
case 1:
fragment = new SecondFragment();
break;
case 2:
fragment = new ThirdFragment();
break;
}
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.content_frame, fragment).commit();
mDrawerList.setItemChecked(position, true);
mTitleSection = mOptionMenu[position];
getSupportActionBar().setTitle(mTitleSection);
mDrawerLayout.closeDrawer(mDrawerRelativeLayout);
}
});
mDrawerList.setItemChecked(0, true);
mTitleSection = getTitle();
mTitleApp = getTitle();
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
R.drawable.ic_drawer, R.string.drawer_open,
R.string.drawer_close) {
public void onDrawerClosed(View view) {
getSupportActionBar().setTitle(mTitleSection);
getSupportActionBar().setLogo(R.drawable.logo);
ActivityCompat.invalidateOptionsMenu(MainActivity.this);
}
public void onDrawerOpened(View drawerView) {
getSupportActionBar().setTitle(mTitleSection);
ActivityCompat.invalidateOptionsMenu(MainActivity.this);
getSupportActionBar().setLogo(R.drawable.logo);
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main_activity_actions, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
switch (item.getItemId()) {
case R.id.action_settings:
Toast.makeText(this, "Settings", Toast.LENGTH_SHORT).show();
;
break;
default:
return super.onOptionsItemSelected(item);
}
return true;
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
mDrawerToggle.syncState();
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
mDrawerToggle.onConfigurationChanged(newConfig);
}
}
I tried adding this line in the code, but no image is being displayed:
getSupportActionBar().setLogo(R.drawable.logo);
I also have a similar concern, in that I want the logo to be clickable and to direct user to the MainActivity

You have to enable Logo feature on you ActionBar by calling getSupportActionBar().setDisplayUseLogoEnabled(true).

Try this in your OnCreate in this order:
getSupportActionBar().setDisplayShowHomeEnabled(true);
getSupportActionBar().setDisplayUseLogoEnabled(true);
getSupportActionBar().setLogo(R.drawable.ic_logo);

In your manifest, you can set android:logo="#drawable/logo" on your <application> node, and/or android:icon="#drawable/icon" for each <activity> node.

In your mainfest file, add under <application>:
android:icon="#drawable/logo"
