NavigationDrawer icon not showing up - android

I am implementing a very simple example of NavigationDrawer. The example works fine, but I have a strange problem. The icon for NavigationDrawer (generally ic_drawer) does not show up in the ActionBar. I have tried using different icon images, but didn't achieved the desired result. Here's the code. The project has only one activity named MainActivity.java.
public class MainActivity extends Activity {
private DrawerLayout mDrawerLayout;
private ListView mListView;
private ActionBarDrawerToggle mDrawerToggle;
private String[] array = new String[] { "Hello", "hola", "namaste",
"salaam" };
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer);
mListView = (ListView) findViewById(R.id.list);
getActionBar().setDisplayHomeAsUpEnabled(true);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(
getApplicationContext(),
android.R.layout.simple_dropdown_item_1line, array);
mListView.setAdapter(adapter);
mListView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
Toast.makeText(getApplicationContext(), array[arg2],
Toast.LENGTH_SHORT).show();
}
});
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
R.drawable.ic_drawer, R.string.open, R.string.close) {
#Override
public void onDrawerClosed(View drawerView) {
// TODO Auto-generated method stub
invalidateOptionsMenu();
}
#Override
public void onDrawerOpened(View drawerView) {
// TODO Auto-generated method stub
invalidateOptionsMenu();
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// TODO Auto-generated method stub
if (mDrawerToggle.onOptionsItemSelected(item))
return true;
return super.onOptionsItemSelected(item);
}
}
And if I comment out the line with code getActionBar().setDisplayHomeAsUpEnabled(true);, the code stops working, meaning NavigationDrawer does not open.
For reference, the xml layout for this activity is:
activity_main.xml
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="#+id/frame"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="change aaaega, hum laaenge" />
<ListView
android:id="#+id/list"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice" />
</android.support.v4.widget.DrawerLayout>
Any suggestions ?
Thanks.

Include this part of code in your program,
#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 onOptionsItemSelected(MenuItem item) {
// call mDrawerToggle.onOptionsItemSelected(), if it returns true
// then it has handled the app icon touch event
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}

Android: Navigation menu not working with button but with touch

Hiho!
I build a navigation drawer into my android app. I used the howto from http://blog.teamtreehouse.com/add-navigation-drawer-android and modified it at one place of the layout.

How to access a drawer layout in all the activities of my android app?

I am developing a quiz app which consists of drawer layout in all the activities.The contents in the drawer is same and i want it in all the activities.By searching google i found a solution that declaring drawer in one activity and inherit in all the activities,it works well too.I am attaching the code below.
Now the problem is that i need Tab in one of by activity so i don't know how to inherit 2 activity in here[which is not possible].
Can any one help me out with this problem?
Simply saying,
I have a option that i can extend only i class what to do if i want two classes?
DrawActivity.java
public void onCreateDrawer() {
// R.id.drawer_layout should be in every activity with exactly the same id.
drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
drawerToggle = new ActionBarDrawerToggle(DrawActivity.this,drawerLayout,R.drawable.ic_drawer2,R.string.app_name,R.string.app_name)
{
public void onDrawerClosed(View view)
{
getActionBar().setTitle(R.string.app_name);
}
public void onDrawerOpened(View drawerView)
{
getActionBar().setTitle(R.string.app_name);
}
};
drawerLayout.setDrawerListener(drawerToggle);
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
//getActionBar().setBackgroundDrawable(new ColorDrawable(Color.RED));
SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
if (settings.getString("logged","").toString().equals("logged")) {
layers = getResources().getStringArray(R.array.layers_array1);
flag=0;
}
else {
layers = getResources().getStringArray(R.array.layers_array);
flag=1;
}
drawerList = (ListView) findViewById(R.id.left_drawer);
drawerList.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,layers));
drawerList.setSelector(R.color.darkgreen);
drawerList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int pos, long arg3) {
selectItemFromDrawer(pos);
}
});
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (drawerToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
drawerToggle.syncState();
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);

handling click event of ActionBarDrawerToggle and ActionBar

I've implemented ActionBarDrawerToggle for NavigationDrawer and also used ActionBar.
How can I handle both click events because both require onOptionsItemSelected(MenuItem item) method?
Is there any other way around?
public class A1 extends AppCompatActivity implements OnItemClickListener {
String[] menu;
DrawerLayout dLayout;
ListView dList;
ArrayAdapter < String > adapter;
ActionBarDrawerToggle drawListener;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_a1);
menu = new String[] {
"Home", "Android", "Windows", "Linux", "Raspberry Pi", "WordPress", "Videos", "Contact Us"
};
dLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
dList = (ListView) findViewById(R.id.left_drawer);
adapter = new ArrayAdapter < String > (this, android.R.layout.simple_list_item_1, menu);
dList.setAdapter(adapter);
dList.setOnItemClickListener(this);
dList.setSelector(android.R.color.holo_blue_dark);
drawListener = new ActionBarDrawerToggle(this, dLayout, R.drawable.ic_draw, R.string.dopen) {
#Override
public void onDrawerOpened(View drawerView) {
// TODO Auto-generated method stub
super.onDrawerOpened(drawerView);
getSupportActionBar().setTitle("Menu");
}
#Override
public void onDrawerClosed(View drawerView) {
// TODO Auto-generated method stub
super.onDrawerClosed(drawerView);
}
};
dLayout.setDrawerListener(drawListener);
getSupportActionBar().setHomeButtonEnabled(true);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
public boolean onCreateOptionsMenu(Menu menu) //for actionbar
{
getMenuInflater().inflate(R.menu.actionbar, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.copy:
return showToast("Copy");
default:
return false;
}
// if(drawListener.onOptionsItemSelected(item))
// {
// return true;
// }
// return super.onOptionsItemSelected(item);
}
public boolean showToast(String message) {
Toast.makeText(getBaseContext(), message, Toast.LENGTH_SHORT).show();
return true;
}
#Override
public void onConfigurationChanged(android.content.res.Configuration newConfig) {
super.onConfigurationChanged(newConfig);
drawListener.onConfigurationChanged(newConfig);
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
drawListener.syncState();
}
#Override
public void onItemClick(AdapterView <? > arg0, View v, int position, long id) {
selectitem(position);
dLayout.closeDrawers();
Bundle args = new Bundle();
args.putString("Menu", menu[position]);
Fragment detail = new DetailFragment();
detail.setArguments(args);
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction().replace(R.id.content_frame, detail).commit();
}
public void selectitem(int position) {
dList.setItemChecked(position, true);
setTitle(menu[position]);
}
public void setTitle(String title) {
getSupportActionBar().setTitle(title);
}
}
I see you're using the latest AppCompat and stuff. Then why complicate the drawer?
Please go through this. You can make a drawer VERY quickly and easily, handle its open and close quite neatly. You don't even need the ActionBarDrawerToggle.
Cheers.

Extending viewpager with navigation drawer

At the moment I have a Base Activity class which implements an action bar across all my activities, I now want to add to this base class so that it implements a navigation drawer. But having a base activity which implements a navigation drawer gives me a lot of conflicting view errors.
My main goal is to have a viewpager activity extend this base activity which implements a navigation drawer, How can I do this? or is there a work around?
Thanks
This is how I am doing this. I don't exactly remember where I took it but it is also changed. In my case I defined it as abstract and extended my MainActivity from this. The reason was to keep the logic related to DrawerActivity in one class so it is not mixed with my business logic.
public abstract class DrawerActivity extends BaseActivity {
private ActionBarDrawerToggle mDrawerListener;
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ListAdapter mDrawerListAdapter;

if (mDrawerList == null) {
throw new RuntimeException(
"Your content must have a ListView"
);
}

I was having the same issue and i just fixed it tonight.
I had a view pager/swipe tab setup that i wanted to add a navigation drawer to.
I built my navigation drawer to extend to my view pager according to this tutorial.
when i tried to extend it to my viewpager class i had to remove the "fragmentactivity" extend for "navigator". this gave me the same issue your having now. it took me 3 hours of research to realize that if i extend class A in class B, then as long as class A is "Extending" the same "supporting Class" that Class B needs, then you wont have that null pointer issue.
here the code: navigation_draw.xml

swipeTabs();

If you are looking for a Navigation Drawer on top of the ViewPager here's what you can do:
Incase if you don't know about the Navigationdrawer properly please check this link(Click Here)
use this code within your relative Layout
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/custom_drawer_layout">
<RelativeLayout
android:id="#+id/relative"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<android.support.v4.view.PagerTabStrip
android:id="#+id/pager_tab_strip"
android:layout_width="match_parent"
android:layout_height="48sp"
android:layout_gravity="top"
android:background="#color/primary"
android:paddingBottom="20dp"
android:textAppearance="#style/PagerTabStripText" />
</android.support.v4.view.ViewPager>
</RelativeLayout>
<fragment
android:id="#+id/notification_drawer_fragement"
android:layout_width="260dp"
android:layout_height="match_parent"
android:layout_gravity="end"
android:name="address to fragment class"
tools:layout="#layout/notification_fragment"
/>
</android.support.v4.widget.DrawerLayout>
Here is what you will get:
1 is the fragment and 2 is the viewPager

i want to set a navigation drawer in android activity but its not working,

I have to implement navigation drawer in my app activity but its not working.It is showing button for the drawer but its not responding.
Here is my code:
// ListView represents Navigation Drawer
private ListView mDrawerList;
private String[] drawerlist = { "Submit Task", "Edit Profile", "Log Out" };
// ActionBarDrawerToggle indicates the presence of Navigation Drawer in the
// action bar
private ActionBarDrawerToggle mDrawerToggle;
private ViewPager viewPager;
private TabsPagerAdapter mAdapter;
private ActionBar actionBar;
// Tab titles
private String[] tabs = { "My profile", "Friend's posts", "Friend List",
"Top posts" };
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_homepage);
// Initilization
viewPager = (ViewPager) findViewById(R.id.pager);
actionBar = getActionBar();
mAdapter = new TabsPagerAdapter(getSupportFragmentManager());
viewPager.setAdapter(mAdapter);
actionBar.setHomeButtonEnabled(false);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
getActionBar().setTitle("OTAKU");
// Getting reference to the DrawerLayout
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.drawer_list);
// Getting reference to the ActionBarDrawerToggle
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
R.drawable.ic_drawer, R.string.drawer_open,
R.string.drawer_close) {
/** Called when drawer is closed */
public void onDrawerClosed(View view) {
getActionBar().setTitle("OTAKU");
invalidateOptionsMenu();
}
/** Called when a drawer is opened */
public void onDrawerOpened(View drawerView) {
getActionBar().setTitle("OTAKU");
invalidateOptionsMenu();
}
};
// Setting DrawerToggle on DrawerLayout
mDrawerLayout.setDrawerListener(mDrawerToggle);
// Creating an ArrayAdapter to add items to the listview mDrawerList
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
R.layout.drawer_list_item, drawerlist);
// Setting the adapter on mDrawerList
mDrawerList.setAdapter(adapter);
// Enabling Home button
getActionBar().setHomeButtonEnabled(true);
// Enabling Up navigation
getActionBar().setDisplayHomeAsUpEnabled(true);
// Setting item click listener for the listview mDrawerList
mDrawerList.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
}
});
// Adding Tabs
for (String tab_name : tabs) {
actionBar.addTab(actionBar.newTab().setText(tab_name)
.setTabListener(this));
}
viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
#Override
public void onPageSelected(int position) {
// on changing the page
// make respected tab selected
actionBar.setSelectedNavigationItem(position);
}
#Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
}
#Override
public void onPageScrollStateChanged(int arg0) {
}
});
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
mDrawerToggle.syncState();
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (mDrawerToggle.onOptionsItemSelected(item))
return true;
if (item.getItemId() == R.id.action_search) {
Intent j = new Intent(getApplicationContext(), Searchresults.class);
startActivity(j);
return true;
}
return super.onOptionsItemSelected(item);
}
/** Called whenever we call invalidateOptionsMenu() */
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
// If the drawer is open, hide action items related to the content view
boolean drawerOpen = mDrawerLayout.isDrawerOpen(mDrawerList);
menu.findItem(R.id.action_search).setVisible(!drawerOpen);
return super.onPrepareOptionsMenu(menu);
}
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.mainmenu1, menu);
return super.onCreateOptionsMenu(menu);
}
#Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
// TODO Auto-generated method stub
viewPager.setCurrentItem(tab.getPosition());
}
#Override
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
// TODO Auto-generated method stub
}
#Override

// TODO Auto-generated method stub
}
I have doubts regarding onOptionsItemSelected(MenuItem item) method.
Here is layout file
<android.support.v4.widget.DrawerLayout
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<!-- The main content view -->
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!-- The navigation drawer -->
<ListView
android:id="#+id/drawer_list"
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.v4.widget.DrawerLayout>
In your onOptionsItemSelected method you aren't doing anything when the user clicks on your drawerToggle. You need to add code to open/close the drawer.
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (mDrawerToggle.onOptionsItemSelected(item))
// code to open/close drawer here
return true;
if (item.getItemId() == R.id.action_search) {
Intent j = new Intent(getApplicationContext(), Searchresults.class);
startActivity(j);
return true;
}
return super.onOptionsItemSelected(item);
}
