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 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);
}
The problem is, that if I press the hardware button for the OptionsMenu, the app freezes and after a half second the fragment view disappears. There is no LogCat error, this is some kind of confusing me. The menu is not working in one out of six fragments. Same problem happens in every fragment.
I want to create an OptionsMenu with the following code.
The OptionsMenu is created in the activity, where the fragments get shown.
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu items for use in the action bar
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main_activity_actions, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// call ActionBarDrawerToggle.onOptionsItemSelected(), if it returns true
// then it has handled the app icon touch event
if (actionBarDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
//return super.onOptionsItemSelected(item);
// Handle presses on the action bar items
switch (item.getItemId()) {
case R.id.action_add:
add();
return true;
case R.id.action_logoff:
Intent i = new Intent(this, Login.class);
startActivity(i);
return true;
default:
return super.onOptionsItemSelected(item);
}
}
XML: main_activity_actions.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/action_add"
android:title="#string/action_add"
android:showAsAction="ifRoom" />
<item android:id="#+id/action_logoff"
android:title="Ausloggen"
android:showAsAction="ifRoom"/>
</menu>
I tried switching around the return statment to true and super.onOptionsItemSelected(item); but nothing changes. The App is developed for Android 2.3
Maybe there are some problems with the hardwarebutton and Fragments in Android version < 3.0.
Here is a guide, how to implement a Actionbar with a softwarebased solution:
http://hmkcode.com/add-actionbar-to-android-2-3-x/
Try to return super.onCreateOptionsMenu(menu) instead true
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main_activity_actions, menu);
return super.onCreateOptionsMenu(menu);
}
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 have a menu that contains just one item.
Button exit;
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// TODO Auto-generated method stub
super.onCreateOptionsMenu(menu);
MenuInflater blowUp = getMenuInflater();
blowUp.inflate(R.menu.exitmenu, menu);
return true;
}
exit=(Button)findViewById(R.id.bexitMenuExit);
if i add listener to exit button , i got excpetion (null pointer), i am sure that there is no syntax error, the button exit is comming from this menu
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:id="#+id/bexitMenuExit"
android:title="Exit"
android:icon="#android:drawable/ic_menu_close_clear_cancel"
></item>
</menu>
what am i doing wrong?
There is no need to initialize Button and this doesn't make sence for me.
Just inflate your Menu and just override onOptionsItemSelected method:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
new MenuInflater(getApplicationContext()).inflate(R.menu.exitmenu, menu);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch(item.getId()) {
case R.id.bexitMenuExit:
// work that will start when you click on this
...
}
}
Also, there is no need to use OnClickListener, for this there is onOptionsItemSelected method and you should use it.
for menu items, as stated by Sajmon, you can use onOptionsIemsSelected function. onClickListener is used by views while this function has been designed to be used specifically by menu items using switch case.
