I use an xml to for my ContextMenu, which is like :
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/Ordermenu" android:title="Order">
<menu android:id="#+id/OrderBySubMenu">
<item android:id="#+id/OrderByASC" android:title="Order ASC" />
<item android:id="#+id/OrderByDESC" android:title="Order DESC" />
<item android:id="#+id/Cancel" android:title="Cancel" />
</menu>
</item>
<item android:id="#+id/ActionAmenu" android:title="Action A"/>
</menu>
I use following code to display the menu, in my onCreateContextMenu
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.layout.my menu, menu);
I manage option click with following code :
public boolean onContextItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.Displaymenu:
//do stuff
return true;
case R.id.OrderByASC:
//do stuff
return true;
case R.id.OrderByDESC:
//do stuff
return true;
default :
return(super.onOptionsItemSelected(item));
}
Starting the Context Menu it display Two options:
Order
Action A
Clicking on Order show a submenu :
Order ASC
Order DESC
Cancel
Now, If the user click on cancel (or click on the hardware back button), no action is specified, so it call super.onOptionsItemSelected(item) which go back to my main activity.
How can I manage to go back to the main menu in such case? i.e. diplay the initial :
Order
Action A
I tried this long ago but i think you will have to override onPrepareOptionsMenu as well to get this to work. This is called before it shows, and you will have to put flags here on what items to show for the user.
Try something like this:
#Override
public boolean onPrepareOptionsMenu(Menu menu)
{
// Clear the previous layout
menu.clear();
if(showMainMenu)
{
// Add main menu items..
menu.add(0, R.id.ordermenu, 0, "True");
}
else
{
// Add sub-menu items
menu.add(0, R.id.ordermenuASC, 0, "True");
}
return super.onPrepareOptionsMenu(menu);
}
So when user clicks a main menu item, change the boolean flag a redo the process.
Finally, it worked only by adding :
case R.id.Cancel:
openContextMenu(findViewById(selected_view_id));
return true;
in public boolean onContextItemSelected(MenuItem item)
selected_view_id is stored by
selected_view_id=v.getId();
in onCreateContextMenu
Hope it will help others.

I have added two menu item . Both of them works good but whenever i press menu button new menu items appear beside the old one . Like below u can see
below is my menu item xml
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:title="Search"
android:icon="#drawable/search_white_24dp"
android:id="#+id/searchmenu"
app:showAsAction="always">
</item>
<item
android:icon="#drawable/settings_white_24dp"
android:title="Setting"
android:id="#+id/settingmenu"
app:showAsAction="always"
/>
</menu>
and here is my code
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu, menu);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.searchmenu:
editText = DuwaManager.openSearchBox(this,
getSupportActionBar(), "DuwaListView");
break;
case R.id.settingmenu:
break;
case R.id.home:
NavUtils.navigateUpFromSameTask(this);
break;
}
please help where i am wrong ?
Sorry this will get to long but , I have second Question
2) My second question i have another menu. xml in which there is share icon in place of search icon , But when i am trying to show on action bar with same code menu item does not show on action bar . below is my another menu xml
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
>
<item
android:title="Share"
android:icon="#drawable/share_white"
android:id="#+id/share_tarika"
app:showAsAction="always"
/>
<item android:title="Setting"
android:icon="#drawable/settings_white_24dp"
android:id="#id/settingmenu"
app:showAsAction="always"/>
</menu>
and its code
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.tarika_menu, menu);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.share_tarika:
break;
case R.id.settingmenu:
break;
}
return super.onOptionsItemSelected(item);
}
Try this
#Override
public void onCreateOptionsMenu(Menu menu ) {
menu.clear();// use menu.clear
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu."your current activity name ", menu);
return true;
}
use menu.clear()
The best to do is as this :
#Override
public void onCreateOptionsMenu(Menu menu ) {
getMenuInflater().inflate(R.menu."your current activity name ", menu);
return true;
}
if you have just one menu. Then set menu from Activity page and return true then no need to clear menu. and no duplicate menu will appear.
But if you use two fragment and have to change activity menu as per fragment then only need to clear menu and reset it with new one.
And if you are using onCreateOptionsMenu(Menu menu) in fragment then remove them.
I am making a simple notepad app and I need help changing the ActionBar drop down menu. I want the main layout to have options for a new note and to reach settings but I need the menu to change when the user enter the note editor. I already have the menus made I just haven't found out how to switch to the different menu when I change to the different layout.
main_menu.xml (inside res/menu folder)
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/idOne"
android:icon="#drawable/ic_launcher"
android:showAsAction="ifRoom|withText"
android:title="Title 1"/>
<item
android:id="#+id/idTwo"
android:icon="#drawable/ic_launcher"
android:showAsAction="ifRoom|withText"
android:title="Title 2"/>
</menu>
In your Activity
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main_menu, menu);
return super.onCreateOptionsMenu(menu);
}
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.idOne:
doSomething();
return true;
case R.id.idTwo:
doSomething2();
return true;
}
return super.onOptionsItemSelected(item);
}
/* Above is presented the standard way of inflating a menu on Activity creation.
* When you need to change it later then you must override this method
* (also in your Activity)
*/
public boolean onPrepareOptionsMenu (Menu menu) {
menu.clear(); //clears the current menu
if (evaluateSomeCondition)
getMenuInflater().inflate(R.menu.another_menu, menu);
else if (evaluateSomeOtherCondition)
getMenuInflater().inflate(R.menu.yet_another_menu, menu);
return super.onPrepareOptionsMenu(menu);
}
I have the problem that my application doesn't show the options menu when I hit the menu button. Debugging shows that the onCreateOptionsMenu(Menu menu) method is not called after hitting the menu button. I have another application with the same code for the menu and there it works. So now my code:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.app_menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.options:
Intent intent = new Intent(this, OptionsActivity.class);
startActivityForResult(intent, 1);
return true;
default:
return super.onOptionsItemSelected(item);
}
}
In res -> menu -> app_menu.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:id="#+id/options" android:title="#string/options" />
</menu>
I have no idea why the onCreateOptionsMenu is not called after hitting the menu button. I hope you guys can help me.
Edit: I'm not using Fragments and the onCreateOptionsMenu is really never called. Not at the start of the app and not when i'm hitting the menu button on my device.
Not sure from your post that you're using Fragments. If so, you must set menu options on by
setHasOptionMenu(true);
call this method from Fragment's onCreate() and the options menu will then be shown.
Try to add these item attributes in your app_menu.xml file:
<item
android:id="#+id/options"
android:orderInCategory="100"
android:showAsAction="never"
android:title="#string/options"/>
You must declare a string for options in Strings.xml
It will call when app starts for the first time not after menu item selected.
#Override
public boolean onMenuItemSelected(int featureId, MenuItem item) {
if (item.getItemId() == R.id.menuitem_id) {
}
return super.onMenuItemSelected(featureId, item);
}
this method will be called after selection
In Manifest file just set target versions as below:
android:minSdkVersion="8" android:targetSdkVersion="10"
I want to have on menu button click to call a function,
that function will popup a window with place for input.
I added to the activity_main.xml the following line
android:onClick="getURL"
and have defined a function in my mainActivity.java:
public void getURL(View view) {...}
however, when i load the app i get:
01-31 09:59:13.479: E/AndroidRuntime(761): FATAL EXCEPTION: main
01-31 09:59:13.479: E/AndroidRuntime(761): android.view.InflateException: Couldn't resolve menu item onClick handler getURL in class com.example.remoteswitch.MainActivity
my menu settings looks like:
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/menu_settings"
android:orderInCategory="100"
android:showAsAction="never"
android:title="#string/menu_settings"
android:onClick="getURL"/>
any ideas why it happens to me?
The way you handle the click on a Menu Item is like this:
First, setup your Options Menu:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater mnuInflater = getSupportMenuInflater();
mnuInflater.inflate(R.menu.your_menu_xml, menu);
return true;
}
Handle the clicks here:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.menu_settings:
// EITHER CALL THE METHOD HERE OR DO THE FUNCTION DIRECTLY
yourMethod();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
And do the function in the yourMethod() here:
private void yourMethod() {
// TODO Auto-generated method stub
}
I am not sure if the onClick method is valid / works when it comes to an Options Menu. The above code works as it should anyway.
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater menuInflater = getMenuInflater();
menuInflater.inflate(R.menu.menuxml_name, menu);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// TODO Auto-generated method stub
switch(item.getItemId())
{
case R.id.menu_settings:
getURL();
break;
}
return super.onOptionsItemSelected(item);
}
Try these override methods into activity so that it can be easy to perform your operation
Just to add something to an old post:
First of all, the parameter of your method should have been MenuItem not View (Bet you already knew that).Secondly, from the official google developer website, it says:
Tip: Android 3.0 adds the ability for you to define the on-click behavior for a menu item in XML, using the android:onClick attribute. The value for the attribute must be the name of a method defined by the activity using the menu. The method must be public and accept a single MenuItem parameter—when the system calls this method, it passes the menu item selected. For more information and an example, see the Menu Resource document.
To use this option, define a method (the method you want to call when the options menu item is clicked) in your activity.For example:
public void showOptionMenuItem(MenuItem item) {
Toast.makeText(getApplicationContext(),
"You have selected the GET URL option", Toast.LENGTH_LONG).show();
}
and then in your XML, you do this:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools" tools:context=".MainActivity">
<item android:id="#+id/action_settings" android:title="#string/action_settings"
android:orderInCategory="100" app:showAsAction="never" />
...
<item android:id="#+id/getUrl"
android:onClick="getURL" //<----
android:title="#string/get_url"/>
</menu>
I'm new to this forum and to android development itself so my question will probably be a very stupid one and i apologize for this .
I began reading the Dev Guide on developer.android.com and until the part with the context menus everything worked pretty fine.
Now i tried to have a context menu with a submenu that contains some checkable items. So i added the submenu and the items to my menu.xml and some item.setchecked(true) methods to my onContextItemSelected(...) method.
menu.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/info"
android:title="#string/info" />
<item android:title="#string/change">
<menu>
<item android:id="#+id/checkable_item1"
android:checked="true"
android:checkable="true"
android:title="#string/hello"/>
<item android:id="#+id/checkable_item2"
android:checkable="true"
android:title="#string/moin"/>
<item android:id="#+id/checkable_item3"
android:checkable="true"
android:title="#string/aloha"/>
</menu>
</item>
</menu>
part of my .java file
...
#Override
public void onCreateContextMenu(ContextMenu menu, View v,
ContextMenuInfo menuInfo)
{
super.onCreateContextMenu(menu, v, menuInfo);
MenuInflater inflater1 = getMenuInflater();
inflater1.inflate(R.menu.context_menu, menu);
}
#Override
public boolean onContextItemSelected(MenuItem item)
{
switch(item.getItemId())
{
case R.id.checkable_item1:
if(item.isChecked()) item.setChecked(false);
else item.setChecked(true);
return true;
case R.id.checkable_item2:
if(item.isChecked()) item.setChecked(false);
else item.setChecked(true);
return true;
case R.id.checkable_item3:
if(item.isChecked()) item.setChecked(false);
else item.setChecked(true);
return true;
default:
return super.onContextItemSelected(item);
}
}
...
Now the problem is that when i open the menu and press one of the checkable items and i can see that the green tick pops up in the little box just before the context menu closes but when i open up the menu again the tick is gone.
Now i don't really know why the tick doesn't stay in the box.
It would be nice if someone could give me hint and tell me what i'm doing wrong.
thanking you in anticipation

I haven't tried it myself but if I read the description here properly (http://developer.android.com/reference/android/app/Activity.html#onCreateContextMenu(android.view.ContextMenu, android.view.View, android.view.ContextMenu.ContextMenuInfo)),
your layout resource will be called every time the menu is created. Since it's "not safe to hold on to a menu after the method returns" , you would need to process the selected item and persist that selection somewhere and then pass the current state of the selectable items into the onCreate with menuInfo, setting checked/unchecked using that info.
If you don't, then the menu will be recreated every time based on your default settings (menu.xml).
