i am creating an android application which includes maps. I have finished the maps but for the reason that I am new to android programming I would like to ask how to create lets say a menu and when a button is clicked like the map button,then the map would be displayed. For the code that I have got now when i run the application the emulator shows the map,but what do i need to do in order to display a menu first instead of the map.For instance to display some options and when the map button is clicked then the map is shown up. Please help, anyone could give me some advice ?? thank you
Here you need to override onCreateOptionsMenu like:
#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;
}
then you need to override onOptionsItemSelected like:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch(item.getItemId())
{
case R.id.map:
// write logic here for open map
Intent intent = new Intent(getApplicationContext(), YourMapActivity.class);
startActivity(intent);
}
return true;
}
And XML file is main.xml
<?xml version="1.0" encoding="utf-8"?>
<menu
xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/map"
android:title="Map"/>
</menu>

I am new to developing Android apps.
I would like to add a settings option menu. The requirement for the app is that when you click settings in the option menu the screen will show a sentence Add beep after ___ counts.
How can I do that, please?
Its on the OnCreateOptions and OnOptionsItemSelected, Plus you need to manipulate the menu folder / menu xml also. Try to read about them and instantiating them is as easy as a switch case, as well as for the functions.
You will need a separate activity/fragment to handle Add beep after ___ counts
Here is the flow, read a little bit more on these. You can find lot of examples on each of these:
Create Main Activity with a menu.xml that has a settings action
Create another activity or a dialog fragment with a layout of
<textview> <edittext> <textview>. This is to show the Add beep
after ___ counts. In MainActivity, on menu action "settings", show this fragment.
You can save the count persistently using preferences
Hope this helps.
mainmenu.xml:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/action_settings"
android:title="#string/settings_label"
android:orderInCategory="100"
app:showAsAction="never" />
</menu>
Activity:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.mainmenu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
switch (id) {
case R.id.action_settings:
Toast.makeText(context, "Add beep after ___ counts.", duration).show();
return true;
default:
return super.onOptionsItemSelected(item);
}
}

I'm trying to make a dynamic action bar in android, right now I'm trying to make a search in the action bar like this.
http://developer.android.com/images/ui/actionbar-searchview#2x.png
However when I click the the search button in the action bar nothing happens.
Here is the menu XML file:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:custom="http://schemas.android.com/apk/res-auto" >
<item android:id="#+id/action_search"
android:title=""
android:icon="#drawable/abc_ic_search"
android:showAsAction="ifRoom|collapseActionView"
android:actionViewClass="android.support.v7.widget.SearchView"/>
<item android:id="#+id/action_menu"
android:title=""
android:icon="#drawable/abc_ic_menu"
android:showAsAction="always"
android:actionViewClass="android.support.v7.widget.ShareActionProvider"/>
Here is the OnCreateOptionsMenu in the 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.main, menu);
MenuItem searchItem = menu.findItem(R.id.action_search);
SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);
return true;
}
I know the icon I have in the action bar is working because I have this code working without problems
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle presses on the action bar items
switch (item.getItemId()) {
case R.id.action_search:
Toast.makeText(getBaseContext(), "Search icon is working", Toast.LENGTH_LONG).show();
return true;
case R.id.action_menu:
Toast.makeText(getBaseContext(), "Menu icon is working", Toast.LENGTH_LONG).show();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
I think it has something to do with this:
android:actionViewClass="android.support.v7.widget.SearchView"/>
Because even when I delete the android.support.v7 jar on the project (I just deleted it to test, I have it back again) I can execute the project without any errors. So maybe the XML file doesn't recognise the android.support.v7 path?
P.S: the action_menu icon doesn't work either.

That is consuming the event, preventing the SearchView from working. Please delete both case sections of this method, as they are incorrect for both of your menu items.
(and, please use this, not getBaseContext(), unless you know what getBaseContext() does)
Here is a sample app showing the use of SearchView.
Additionally android.support.v7.widget.SearchView throws NullPointerException at onCreateOptionsMenu() with default configuration.
Solved by changing it to android.widget.SearchView
The answer by #CommonsWare is valid also. It is more likely to be the correct answer.
I am new to this android.In my application when user clicks Menu button ,i want to show 1 option at the bottom of the screen(background should remain as the current screen).Simply i have to say means if user clicks menu button as like pop up window 1 option should come at the

Please help me.Thanks in advance.
Menu is generally used to give extra functionality to an application.
To achieve your goal you have to implement menu, which will open when you click menu button of device, like below.
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// TODO Auto-generated method stub
MenuInflater inflater=getMenuInflater();
inflater.inflate(R.menu.optionmenu, menu);
return super.onCreateOptionsMenu(menu);
}
R.menu#
<?xml version="1.0" encoding="utf-8"?>
<menu
xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/Color" android:title="Color">
<menu>
<item android:id="#+id/RedColor" android:title="Red"/>
<item android:id="#+id/GreenColor" android:title="Green"/>
</menu>
</item>
</menu>
and if you want to do any action on click of option menu, you have to override onOptionsItemSelected to do action on click of menu option, like below.
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// TODO Auto-generated method stub
if(item.getItemId()==R.id.RedColor)
{
Toast.makeText(MenuOptionDemoActivity.this,"Red Color Selected" ,1000).show();
}
else if(item.getItemId()==R.id.GreenColor)
{
Toast.makeText(MenuOptionDemoActivity.this, "Green Color Selected", 1000).show();
}
return super.onOptionsItemSelected(item);
}
}
A clear and simple tutorial to implement menu in your app.
That can be done, but the solution is too long for me to post here, so instead follow the link to a tutorial for creating a menu
http://www.androidhive.info/2011/09/how-to-create-android-menus/
Just as a brief overview of the tutorial - You start by overriding the onCreateOptionsMenu method. In this you inflate your menu. Then you override the onItemSelected method, in which you pu a switch to determine which option phase been selected, though in your case it will only be one item. Finally you have to create an XML file which contains all the options for your menu.
I have created menu button which have two functions bookmark and home button.
This is working well in all the android version without android 3.0
do here any ways ? so my menu button will be display also in android 3.0 with all the version.
my code:-
#Override
public boolean onOptionsItemSelected(MenuItem item)
{
switch (item.getItemId())
{
case R.id.menu_bookmark:
db.updateContact(new Contact(itemN,imageStatus));
return true;
case R.id.home_page:
Intent i = new Intent(imageTouchs.this, Comics.class);
startActivity(i);
return true;
default:
return super.onOptionsItemSelected(item);
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu)
{
MenuInflater menuInflater = getMenuInflater();
menuInflater.inflate(R.layout.menu, menu);
return true;
}
and my androidmanifest.xml :-
<uses-sdk
android:minSdkVersion="11"
android:targetSdkVersion="15" />
menu.xml :
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/menu_bookmark"
android:title="Bookmark"
android:showAsAction="ifRoom|withText" />
<item android:id="#+id/home_page"
android:title="Home"
android:showAsAction="ifRoom|withText" />
</menu>
any menu is not display in action bar
The "overflow' button will only show up when there isn't a physical menu button on the device. This is the standard behavior for the ActionBar.
You can actually set the value of your AVD to specifically not have a menu button when you are configuring the image.
Here is a SO question addressing this same thing: Action bar overflow not displayed
If you are talking about the OverFlowMenu icon, to the best of my knowledge, it cannot be achieved (forced) using the standard Android Support Library.
If you must have an OverFlowMenu (forced), you will need to use the ActionBarSherlock library. Go through a couple of my answers where I have a few fairly detailed suggestions on how to achieve that:
https://stackoverflow.com/a/13307583/450534
https://stackoverflow.com/a/13180285/450534
NOTE: As already mentioned in both my answers linked above, this is not recommended to ensure users get a seamless UI on their devices. And also, if you must absolutely force the OverFlowMenu, you will need to use an older version of ABS, which is again, not recommended.
I have been looking online for a while, and there are very little tutorials on how to do this. Even the google docs have very vague info on how to put this stuff up there! I am sure its subtle, but I can't understand the terminology because I am still fairly new to Android. I would like to be able to get the Action Overflow icon to the right side of the ActionBar. Putting the view control was pretty understandable using the docs and example code when creating a project, but it does not have one for the Action Overflow. Thanks in advance!
Edit: I should probably elaborate. I would like the menus to default being under the action overflow. I found an eye opener answer to a similar question, but it only tells you how to put the menus at the top. How can I force them to go under the list? Is it even possible to force that? Thanks!
If you use API-11, it's not problem. If lower I am inviting you to this topic :
The best way to create drop down menu in android 2.x like in ICS
In the case when API-11 and higher you must :
Create menu xml like this :
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/item_refresh"
android:icon="#drawable/ic_menu_refresh"
android:title="Refresh"
android:showAsAction="ifRoom|withText" />
<item
android:id="#+id/item_save"
android:icon="#drawable/ic_menu_save"
android:title="Save"
android:showAsAction="ifRoom|withText" />
</menu>
And create code like this :
public class MainActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// gets the activity's default ActionBar
ActionBar actionBar = getActionBar();
actionBar.show();
actionBar.setDisplayHomeAsUpEnabled(true);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main, menu); //inflate our menu
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item){
switch(item.getItemId()) {
case R.id.item_refresh:
//click on refresh item
break;
case R.id.item_save:
//click on save item
break;
}
return true;
}
Good Luck!
