Here is the code where I am accessing drawer when image clicked in another activity
drawerImg.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
DrawerActivity.openDrawer();
}
});
I am implementing navigation drawer in my android application. I have a separate activity for navigation drawer. I will extend the drawer activity where ever I want.
Now the issue is I have drawer image in bottom bar. When I click the image in bottom app bar I have to open the drawer. For one activity I want to open drawer by clicking the image in bottom bar. I know if I extend the drawer activity the hamburger icon will visible in toolbar that I don't want to achieve in this activity.
So how to avoid this scenario by using bottom bar?
Extend your draweractivity to your other activity.
try this:
public class MainActivity extends DrawerActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_activity);
drawerImg.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
openDrawer();
}
});
}
}
Try implementating an interface.
Create an interface where you want to access the drawer activity.
public interface OnDrawerListener{
void onDrawerClick();
}
OnDrawerListener onDrawerListener;
drawerImg.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
onDrawerListener.onDrawerClick();
}
});
Then implement this interface in your DrawerActivity.
public class DrawerActivity extends AppCompatActivity implements InterfaceActivity.OnDrawerListener{ //InterfaceActivity is activity where you have created your interface.
private InterfaceActivity.OnDrawerListener someInterface;
#Override
protected void onCreate(Bundle savedInstanceState) {
someInterface = (InterfaceActivity.OnDrawerListener) this;
}
//Your interface override
#Override
public void onDrawerClick(){
openDrawer();
}
}

To open Activity like this:

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 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
I need to extend Two classes from a Single Class.My class Wants to extend Both ListActivity & MainActivity.

EDIT
I need to Extend it.Because the MainActivity has the navigation drawer.Now ConnectionEditActivity
doesn't shows the navigationDrawer nor the ActionBar .But i need to show the ActionBar
Any Suggestions ??
In Java you can't extend multiple classes, and for a good reason. Take for example what you are trying to accomplish by extending MainActivity and ListActivity. In your new class, when you call:
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
...
}
Which onCreate() are you overriding? The one from ListActivity, or the one from MainActivity?
What the link you posted is saying is that instead of inheriting from another object, you compose your new object of the one you are trying to use. For example:
public class NewClass extends OldClass1 {
private OldClass2 mOldClass2 = new OldClass2();
#Override
public methodFromOldClass1() {
}
public methodFromOldClass2() {
mOldClass2.methodFromOldClass2();
}
}
The problem with this approach is that the methods from MainActivity and ListActivity are still going to have the same name, which although you can work around, it will become a headache quickly.
So the problem is a result of how you designed your class hierarchy. You will need to think about what functions you need from MainActivity, and what functions from ListActivity and choose how to reimplement your objects.
My Suggestion, since ListActivity only makes it slightly easier to work with lists (not that much easier) you can just skip it and implement the code related to the list on your own, and that way you can just extend MainActivity
You need to start by identifying what parts of MainActivity you need to inherit from, and what do you need from ListActivity.
Then, you have various possibilities:
Trivially, not extending ListActivity. Extending ListActivity only provides you with utility methods to work with the ListView, but you can totally have a ListView in an Activity without it being a ListActivity.
Create a utility class that contains extracted methods you need from MainActivity and call these methods from both your new class and MainActivity.
Modify MainActivity so that it extends ListActivity. After all it does contain a ListView (you'd loose the ActionBar thing, though).
I am using the [SlidingMenu][1] Library in my App and have made a menu but I am not sure how to customize this.
First, the Up Navigation button on the action bar does not pull up the menu. It just does not do anything when clicked. The menu works by sliding in anywhere on the screen but not with that button.
Also, is there a way to change that up navigation '<' icon and make it work like Google + or others with the animation of the three horizontal lines?
My code is as follows:
public class BaseActivity extends SlidingFragmentActivity {
private int mTitleRes;
protected ListFragment mFrag;
public BaseActivity(int titleRes) {
mTitleRes = titleRes;
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setTitle(mTitleRes);
// set the Behind View
setBehindContentView(R.layout.menu_frame);
if (savedInstanceState == null) {
FragmentTransaction t = this.getSupportFragmentManager().beginTransaction();
mFrag = new MenuListFragment();
t.replace(R.id.menu_frame, mFrag);
t.commit();
} else {
mFrag = (ListFragment)this.getSupportFragmentManager().findFragmentById(R.id.menu_frame);
}
// customize the SlidingMenu
SlidingMenu sm = getSlidingMenu();
sm.setShadowWidthRes(R.dimen.shadow_width);
sm.setShadowDrawable(R.drawable.shadow);
sm.setBehindOffsetRes(R.dimen.slidingmenu_offset);
sm.setFadeDegree(0.35f);
sm.setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
}
And the main activity:
public class StatusActivity extends BaseActivity {
public StatusActivity() {
super(R.string.title_status_page);
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_status);
setSlidingActionBarEnabled(false);
..
..
Try this:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item.getItemId() == android.R.id.home) {
getSlidingMenu().showContent();
}
return false;
}
