How to create Spinner Action Item in Action Bar - android

Anyone know how to create the submenu with radio buttons like in the screenshot?

If you want a submenu with checkable radio buttons you should use something like that:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<group android:checkableBehavior="single">
<item android:id="#+id/red"
android:title="#string/red" />
<item android:id="#+id/blue"
android:title="#string/blue" />
</group>
</menu>
And then in the code:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.red:
return true;
case R.id.blue:
return true;
default:
return super.onOptionsItemSelected(item);
}
}

drawable states won't update on action bar

I have an action bar which contains an item shuffle_action.
I have used below case in the onOptionsItemSelected(MenuItem item) function.
switch (item.getItemId()){
case R.id.action_shuffle:
if(MusicService.shuffle) {
item.setChecked(false);
Toast.makeText(this,String.valueOf(item.isChecked()),
Toast.LENGTH_SHORT).show();// returns false
musicService.clearShuffle();
}
else {
item.setChecked(true);
Toast.makeText(this,String.valueOf(item.isChecked()),
Toast.LENGTH_SHORT).show();// returns true
}
musicService.setShuffle();
break;
}
Now this thing works perfectly as i want it to work.
<item
android:id="#+id/action_shuffle"
android:icon="#drawable/shuffle_drawable"
android:title="Shuffle"
app:showAsAction="ifRoom"
android:checkable="true"
android:checked="false"
/>
shuffle_drawable.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true"
android:drawable="#drawable/shuffle_pressed"/>
<item
android:state_checked="false"
android:drawable="#drawable/ic_shuffle_black_18dp"/>
</selector>
The thing is that when the state changes the drawable won't change.Why is this happening?

Adding a button to the Action Bar in Android?

For some reason, I cannot get my button to appear on the Action Bar. I have defined it in an XML file in /res/menu, along with inflating it and listening for an action. The icon is present in /res/drawable-hdpi. And nothing of interest shows in logcat. :(
XML:
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:id="#+id/logout"
android:icon="#drawable/logout"
android:title="Logout"
android:orderInCategory="100"
android:showAsAction="always" />
</menu>
Code in main activity:
public class MainActivity extends ActionBarActivity {
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main_activity_actions, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle presses on the action bar items
switch (item.getItemId()) {
case R.id.logout:
//logout code
return true;
default:
return super.onOptionsItemSelected(item);
}
}
//rest of app
}
I followed this question for my initial problem, and it didn't help. How to add button in ActionBar(Android)?
Try with this change:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:yourapp="http://schemas.android.com/apk/res-auto" >
<item android:id="#+id/logout"
android:icon="#drawable/logout"
android:title="Logout"
android:orderInCategory="100"
yourapp:showAsAction="always" />
</menu>

Android Menu onOptionsItemSelected styling menu items

I'm trying to highlight menu item title when it is selected in action bar and display its corresponding view in a fragment below. Fragment loading is working good but I'm not able to style menu items when they are clicked.
What I would like to have is something like below mentioned methods-
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// item.setSiblingsStyle(R.style.passive_menu_item);
// item.setStyle(R.style.active_menu_item);
}
Is it possible to style menu title in "onOptionsItemSelected" method? Please help !
You could try to use selector definition:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android"
<item android:state_pressed="true" android:color="#color/blue_light"/> <!-- pressed -->
<item android:state_enabled="false" android:color="#color/grey_cloud"/> <!-- focused -->
<item android:color="#color/black"/> <!-- default -->
</selector>
I've figured using just text is not a good way. So I decide to add icons and use state of items to toggle by maintaining few variables. Here is an implementation:
private current_selected_menu;
private main_menu;
public void updateMenuState(){
if (main_menu==null){
return;
}
int sz = main_menu.size();
for(int i=0;i<sz;i++){
if(main_menu.getItem(i).getItemId()==current_selected_menu){
main_menu.getItem(i).setEnabled(false);
}
else{
main_menu.getItem(i).setEnabled(true);
}
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.sample_menu, menu);
current_selected_menu = menu.getItem(0).getItemId(); // I'm using first item as enabled by default
main_menu = menu;
int sz = menu.size();
for(int i=0;i<sz;i++){
if(menu.getItem(i).getItemId()==current_selected_menu){
menu.getItem(i).setEnabled(false);
}
else{
menu.getItem(i).setEnabled(true);
}
}
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.item1:
// Do something
current_selected_menu = item.getItemId();
updateMenuState();
return true;
case R.id.item2:
// Do something
current_selected_menu = item.getItemId();
updateMenuState();
return true;
default:
// Do Something
return super.onOptionsItemSelected(item);
}
}
As suggested by Xingchen, One can use selectors to define multiple icons. Below is a sample implementation:
icon_selector.xml file in res/drawable:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:drawable="#drawable/icon_passive" android:state_enabled="false"/>
<item android:drawable="#drawable/icon_active" android:state_enabled="true"/>
</selector>
Note: icon_passive.png and icon_active.png are two image files used as icons.
sample_menu.xml file in res/menu:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/menu1" android:icon="#drawable/icon_selector" android:title="menu1" android:showAsAction="always|withText" android:visible="true"></item>
<item android:id="#+id/menu2" android:icon="#drawable/icon_selector" android:title="menu2" android:showAsAction="always|withText" android:visible="true"></item>
<item android:id="#+id/menu3" android:icon="#drawable/icon_selector" android:title="menu3" android:showAsAction="always|withText" android:visible="true"></item>
</menu>
I feel there could be better ways than above mentioned. I'll keep this open. Please feel free to suggest better solutions or better practices : )

handle clicks on submenus in android

I am new to android and stuck at the point where i have to detect clicks on submenus that are defined in XML file
my XML file is :
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/ccard_menu1"
android:title="Select from Profile?"
></item>
<item android:id="#+id/ccard_menu2"
android:title="Add Field"
>
<menu >
<item android:id="#+id/submenu1"
android:title="Add Products"
></item>
<item android:id="#+id/submenu2"
android:title="Add Clients"
></item>
<item android:id="#+id/submenu3"
android:title="Add a Custom Field">s</item>
</menu>
</item>
</menu>
how do i detect clicks on "submenu 1,2,3" in onOptionsItemSelected method?
how do i have to structure the switch case?
I you are looking for something like this:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.your_menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.submenu1:
// do something
return true;
case R.id.submenu2:
//do something else
return true;
// etc..
default:
return super.onOptionsItemSelected(item);
}
}
Please correct me if I am mistaken.
