Android: Navigation-Drawer on all activities

Android: Navigation-Drawer on all activities - java

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);
}

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.

I extended myClass about drawer class, I see layout myClass but I cannot click in buttons

I have code like this:
DrawerLayout
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<android.support.v4.widget.DrawerLayout
android:id="#+id/drawerLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView
android:id="#+id/drawerList"
android:layout_width="180dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#FFFFFF"
android:choiceMode="singleChoice"
android:divider="#android:color/darker_gray"
android:dividerHeight="1dp"
android:entries="#array/Functions" />
</android.support.v4.widget.DrawerLayout>
</RelativeLayout>
DrawerActivity:
public class Drawer extends Activity {

return super.onOptionsItemSelected(item);
}
private void selectItem(int position) {
drawerLayout.closeDrawers();
switch (position) {
case 0:

break;
case 1:
// intent = new Intent(this, 1Act.class);

break;
case 3:
intent = new Intent(this, 3Act.class);
startActivity(intent);

case 4:

break;
}
}
private class DrawerItemClickListener implements ListView.OnItemClickListener {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
selectItem(position);
}
}
}
FirstActivity:
public class 0Act extends Drawer implements ActionBar.TabListener {
ActionBar.Tab t1,t2,t3;
ActionBar actionBar;
Button oneButton;
final CharSequence[] items = {"1", "2", "3", "4"};
AlertDialog.Builder ad;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.0Act);
actionBar = getActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
t1 = actionBar.newTab().setText("1");
t2 = actionBar.newTab().setText("2");
t3 = actionBar.newTab().setText("3");
t1.setTabListener(this);
t2.setTabListener(this);
t3.setTabListener(this);
actionBar.addTab(t1);
actionBar.addTab(t2);
actionBar.addTab(t3);
actionBar.setSelectedNavigationItem(0);
oneButton= (Button) this.findViewById(R.id.oneButton);
oneButton.setOnClickListener(new View.OnClickListener(){#Override public void onClick(View v) {ad.show();}});
ad = new AlertDialog.Builder(getActivity());
ad.setTitle("Menu");
ad.setItems(items, new DialogInterface.OnClickListener() {public void onClick(DialogInterface dialog, int item) {}});
}
}
I see the drawer - I can click on the drawer but I cannot click on any buttons from the first activity. What is going wrong?
Before added drawer to many activities all working good but now I dont see any error and activity dont working.

Mention super.onClick(v); inside onClick method for your Item1Activity Class

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;

</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.

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,

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.

<string name="action_websearch">Web search</string>
<string name="app_not_available">Sorry, there\'s no web browser available</string>
<string name="_11">11</string>

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"
