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

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????
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;

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'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

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.
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.
Example :Custom Navigation Drawer
I had my project in a project named "NavigationDrawer" and realised that considering this was an app that had more than a Nav Drawer in it that it should be changed and renamed to something relevant.
I tried to import the project but it kept saying that there were no source files found, so I started to do it the old fashioned way (copying and pasting everything over making sure that I changed package names etc). But now when I try to run the program its saying that it cant find the MainActivity method. It keeps saying "Class 'MainActivity' is never used" and without it, my program wont run obviously.
I'm at my wits end here guys haha, I know its likely that I haven't edited one of the files or something but if you could point me in the right direction that would be great.
My code:
package com.example.ColeraineTown;
imports....
public class MainActivity extends Activity {
private DrawerLayout DrawerLayout;
private ListView DrawerList;
private ActionBarDrawerToggle DrawerToggle;
private CharSequence DrawerTitle;
private CharSequence Title;
private String[] pageArray;

You should declare it in the Android Manifest for that project.
<activity android:name="com.example.ColeraineTown.MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
