When using the Android Eclipse IDE, how do I add a menu that is triggered by the phone menu button such that it has to have an "About" choice that displays an "About my app" dialog and a "Quit" choice that exits the app?
To create a content menu with about a quit items, please add all of the following to your project after first removing any other attempts at an about menu that might potentially conflict with this code. Let Eclipse help you add the required imports or peruse the android documentation as you try to build this, and after everything's in place it should just work :-)
In /res create a folder menu containing a file main.xml with the following xml:
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/action_settings"
android:orderInCategory="100"
android:showAsAction="never"
android:title="#string/action_settings"/>
<item
android:id="#+id/action_quit"
android:orderInCategory="101"
android:showAsAction="never"
android:title="#string/action_quit"/>
</menu>
In MainActivity.java add the following after your onCreate is closed:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_settings:
AboutDialog about = new AboutDialog(this);
about.setTitle(“About “my app);
about.show();
return true;
case R.id.action_quit:
System.exit(0);
return true;
}
}
Add a new java file but extend Dialog instead of Activity, like shown:
public class AboutDialog extends Dialog {
public AboutDialog(Context context) {
super(context);
}
#Override
public void onCreate(Bundle savedInstanceState) {
setContentView(R.layout.dialog_about);
}
}
Finally, add a new layout dialog_about.xml like so:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/ScrollView01"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
</ScrollView>
Of course you’ll need to add another layout and content inside the ScrollView, and you may want other features in your menu and your quit item could use a confirmation (possibly). But this should get you started.

I am having an issue where i have 2 items in my action bar (one 'refresh' button and one 'Save' Button, but for some reason they do not show, instead they are nested inside an options menu (3 dots). Would anyone know how to remove the 3 dots menu and display my 2 items? I have tried many things but ultimately I just end up removing all three items. Thanks in advance.
Here is my code
add_event_action.xml (this is my menu xml)
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/action_refresh"
android:showAsAction="always"
android:icon="#drawable/ic_action_refresh"
android:title="Refresh"/>
<item
android:id="#+id/action_save"
android:showAsAction="always"
android:title="#string/save"/>
</menu>
Here is my Java class
public class RandomActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_events_list);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.add_event_action, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
// action with ID action_refresh was selected
case R.id.action_refresh:
Toast.makeText(this, "Refresh selected", Toast.LENGTH_SHORT)
.show();
break;
// action with ID action_settings was selected
case R.id.action_save:
Toast.makeText(this, "Save selected", Toast.LENGTH_SHORT)
.show();
break;
default:
break;
}
return true;
}
}
If I understood correctly, you need two menu buttons in your toolbar.
This works for me, place it in your menu.xml:
<item
android:id="#+id/done"
android:title="#string/done"
app:showAsAction="always|withText"/>
Try to use app:showAsAction instead of android:showAsAction
To expand on the other answers somewhat:
When your activity extends from AppCompatActivity, your menu items should use app:showAsAction. When your activity does not (that is, when you're not using the AppCompat support libraries), your menu items should use android:showAsAction.
Documentation: http://tools.android.com/tips/lint-checks
AppCompatResource
Summary: Menu namespace
Priority: 5 / 10
Severity: Error
Category: Correctness
When using the appcompat library, menu resources should refer to the
showAsAction in the app: namespace, not the android: namespace.
Similarly, when not using the appcompat library, you should be using the android:showAsAction attribute.
I am trying to add a page in "Settings" menu option on top of the android app. The app by default had the 3 dots on top right corner and when I click on it, it doesn't go anywhere and now I am trying to implement settings to my app. What I have done so far is following,
Created xml file in /res/xml folder called preferences.xml with following content;
<?xml version="1.0" encoding="utf-8"?>
<preferencescreen xmlns:android="http://schemas.android.com/apk/res/android">
<preference android:key="sample"
android:summary="can open other activity"
android:title="click here">
</preference>
<edittextpreference android:key="Name"
android:summary="Add user Name."
android:title="Your Name">
</edittextpreference>
</preferencescreen>
Then I have created a new java class called Preferences in /src/main/java/package/ with following content;
package com.domain.mobile.tipcalculator.app;
import android.preference.PreferenceFragment;
import android.os.Bundle;
public class Preferences extends PreferenceFragment {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.preferences);
}
}
Then to my understanding this is all I need. I m not getting any errors on compilation time but when I click on the 3 dots on top right and click on "Settings" I still don't see the page come up. Any ideas? Thank you.
P.S. I am using PreferenceFragment because my min sdk requirement is 11.
To use menus like that, you have to create a menu xml file then inflate it and then switch between the menu item ids so that you can handle click events like the following:
#Override
public boolean onCreateOptionsMenu(Menu menu)
{
MenuInflater menuInflater = getMenuInflater();
menuInflater.inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item)
{
switch (item.getItemId())
{
case R.id.preferences:
startActivity(new Intent(this, PreferenceActivity.class));
return true;
case R.id.settings:
startActivity(new Intent(this, SettingsActivity.class));
return true;
default:
return super.onOptionsItemSelected(item);
}
}
You should be able to achieve what you need this way and I hope this helped.
I wanted to display Menu in ActionBar using ActionBarActivity.
I am getting options menu while clicking options button instead of displaying in the top of action bar.
I need the options menu at top instead of clicking the options menu from 2.3 onwards
My Code :
public class MainActivity extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ActionBar actionBar = getSupportActionBar();
actionBar.setSubtitle("mytest");
actionBar.setTitle("Testing");
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction().add(R.id.container, new PlaceholderFragment()).commit();
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main_action, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.menu_item_one:
Toast.makeText(this, "clicked search", Toast.LENGTH_SHORT).show();
break;
default:
break;
}
return super.onOptionsItemSelected(item);
}
/**
* A placeholder fragment containing a simple view.
*/
public static class PlaceholderFragment extends Fragment {
public PlaceholderFragment() {}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_main, container, false);
return rootView;
}
}
}
My XML file :
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/menu_item_one"
android:icon="#drawable/ic_launcher"
android:showAsAction="always"
android:title="#string/action_settings"/>
<item
android:id="#+id/menu_item_two"
android:icon="#drawable/ic_launcher"
android:showAsAction="always"
android:title="#string/action_settings"/>
</menu>
Try it:
Create XML file on "../res/menu/menu_main.xml"
manu_main.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/menu_settings"
android:showAsAction="never"
android:icon="#android:drawable/ic_menu_settings"
android:title="#string/menu_settings"/>
</menu>
The option "never" on "showAsAction", important, if you put that the option always show on ActionBar.
Then now we must asociate this option on the MainActivity.java (class whatever you want).
MainActivity.java
public class MainActivity extends Activity {
...
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
Now that we define the elements of our action bar is knowing how to respond to keystrokes made by the user about them.
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.menu_settings:
Log.i("ActionBar", "Settings!");;
//open Activity,Fragments or other action
return true;
default:
return super.onOptionsItemSelected(item);
}
}
If you have morer options on your menu only add item on XML menu_main.xml and on the principal class add other "case".
For Example:
MainActivity.java
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.menu_save:
Log.i("ActionBar", "Save!");;
//open Activity,Fragments or other action
return true;
case R.id.menu_settings:
Log.i("ActionBar", "Settings!");;
//open Activity,Fragments or other action
return true;
default:
return super.onOptionsItemSelected(item);
}
}
menu_main.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/menu_settings"
android:showAsAction="never"
android:icon="#android:drawable/ic_menu_settings"
android:title="#string/menu_settings"/>
<item
android:id="#+id/menu_save"
android:showAsAction="never"
android:icon="#android:drawable/ic_menu_save"
android:title="#string/menu_save"/>
</menu>
It is possible that this is because your device has an options button that would open the menu, so Android don't draw the launcher icon.
http://blog.vogella.com/2013/08/06/android-always-show-the-overflow-menu-even-if-the-phone-as-a-menu/
Try with return super.onCreateOptionsMenu(menu); instead of return true in your onCreateOptionsMenu method according to below android document...
http://developer.android.com/guide/topics/ui/actionbar.html#ActionItems
As per above android document...
The ActionBar APIs were first added in Android 3.0 (API level 11) but they are also available in the Support Library for compatibility with Android 2.1 (API level 7) and above.
So, If you want ActionBar in android 2.3 then you have to use Android Support Library.
Edit:
Your menu XML would need to look like this:
<?xml version="1.0" encoding="utf-8"?>
<menu
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:yourapp="http://schemas.android.com/apk/res-auto"
>
<item android:id="#+id/item_menu_ok"
android:icon="#drawable/ic_action_ok"
android:title="#string/ok"
yourapp:showAsAction="always"/>
<item android:id="#+id/item_menu_cancel"
android:icon="#drawable/ic_action_cancel"
android:title="#string/cancel"
yourapp:showAsAction="always"/>
</menu>
Replace yourapp with your app name or any namespace.
I'm not 100% sure, but it looks like your menu XML file should have a menu in it. In the menu, add the items. Like this:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/main_menu" >
<item...
<item...
</menu>
Perhaps this works.
There are also a few other things to remember in general. Android decides by itself what to show in the ActionBar (depending on what fits there and other parameters). What does not fit in the ActionBar goes into the overflow.
Do this in your oncreate()
ActionBar actionBar = getActionBar();
actionBar.show();
This should do what you want.
Action Bar
Ok, let's try another answer. If, for whatever reason, Android decides not to show the items in the action bar, then what your are seeing is indeed the correct behaviour. Items not in the action bar are shown in overflow.
One reason items don't show in the action bar is because they don't have a icon defined.
You do define an icon, as this,
android:icon="#drawable/ic_launcher"
and I suspect this is the problem. The launcher icon is of different size (larger) than the action bar items (smaller). Try defining the icon in correct size and see if it is displayed.
http://developer.android.com/design/style/iconography.html
Edit: There is an action bar icon pack to get you started so you can test to see if it works. Download it and use eclipse to import some icon..
I am very new to Android and Java programming. What I am trying to do is to get Actionbar with couple of tabs (11 in final). I have managed to install ActionBar Sherlock but then I am stuck with adding tabs to actionbar. From what I read it looks that also I would need to add separate Fragment for each tab. Is there a simple solution how to make that work.
You don't need to have a fragment per tab in the action bar. It should just be as simple as defining your menu in xml, then in your activity initialising the action bar with your menu.
For instance your menu.xml:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/my_menu_item"
android:showAsAction="always|withText"
android:title="Tab name here"/>
</menu>
Then in your activity override onCreateOptionsMenu:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getSupportMenuInflater().inflate(R.menu.my_menu, menu);
return super.onCreateOptionsMenu(menu);
}
Then you'll need to override onOptionItemSelected to respond to when a tab is pressed:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.my_menu_item:
//do something
}
return super.onOptionsItemSelected(item);
}
On pressing menu button , I have 2 options : Add & more.
On click of more i have 3 options : Organize ,Export & Exit
On click of Organize i want other 5 options.
On click of more i get my submenu. But i want other 5 options on click of organize.How do i proceed???
My code in parts is as follows :
XML file-------------------------------
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/more"
android:title="#string/moreMenu"
android:icon="#drawable/icon">
<menu>
<item android:id="#+id/Organize"
android:title="#string/Organize" />
<item android:id="#+id/Export"
android:title="#string/Export" />
</menu>
</item>
<item
android:id="#+id/add"
android:title="#string/addMenu"
android:icon="#drawable/add"/>
</menu>
Java-------------------------
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.Toast;
public class ToDoList extends Activity {
Menu menu;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.todolist);
}
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
getMenuInflater().inflate(R.layout.categorymenu, menu);
return true;
}
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.more:
Toast.makeText(this, "You pressed more!", Toast.LENGTH_LONG).show();
//(What needs to be done from here)
return true;
case R.id.add:
Toast.makeText(this, "You pressed add!", Toast.LENGTH_LONG).show();
return true;
}
return false;
}
public boolean onPrepareOptionsMenu(Menu menu) {
return true;
}
}
As can be seen in Creating Menus sub menus can not contain sub menus.
You could show a Context menu after clicking on the item in the options menu.
This could show your five more options in a floating view above the screen.
You have to overwrite the onCreateContextMenu to create a ContextMenu and I think you have to call the contextMenu manually in the onOptionsItemSelected method. For resources on how to create the context menu see this paragraph in the article mentioned above.
To open the ContextMenu you can call openContextMenu in your Activity. You may need to register the menuitem before to enable your activity to find the correct context menu.
