</activity>
</application>
I am adding the up button in second activity ,. it is showing but not working .
And also trying to add action bar buttons in secondActivity . Menu file is as below :
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:Digicare="http://schemas.android.com/apk/res-auto"
xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/item_back"
android:icon="#drawable/home2"
Digicare:showAsAction="ifRoom"
android:title="Home">
</item>
</menu>
this is my java file of secondActivity :
it never comes in the if statement .
i put log in it , so i get it that it never comes in if statement
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if ( item.getItemId() == R.id.home){
Log.w("asdfasdfasdf","asdfasdf");
Intent upIntent = NavUtils.getParentActivityIntent(this);
NavUtils.navigateUpTo(this, upIntent);
}
return super.onOptionsItemSelected(item);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater Mymenu = getMenuInflater();
Mymenu.inflate(R.menu.item_menu,menu);
return super.onCreateOptionsMenu(menu);
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.items);
ActionBar actionBar = getActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);
}
These are problems .
how to done this ????

First issue
This is a duplicate of this question. I think that it doesn't show up because you have an options button on your device.
See this post about modifying this behavior in reflection (however, I'm not sure I would recommend it, as people have expectations about their device's behavior).
Second issue
If I followed your code correctly, then the item id is item_back and not R.id.home...

Targeting different APIs for contextual menu

I returned to reading this book today after finishing my simple program and publishing it, and I stopped on chapter 18 which is about context menus, anyways I read this:
With contextual actions the situation is more complicated , you still define one menu resource but you implement two separate sets of callbacks , one for contextual action bar and one for floating context menus.
I'm worried now since I only looked at a reference to implement context menus, I didn't read about it much, so I didn't actually target the two things.
I have a context menu with options without icons, only text.
Is this going to be a problem?
I've tested this on API 8 and 17 and 18 but it's the same.
menu.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:id="#+id/menu_rename" android:title="Rename" />
<item android:id="#+id/menu_delete" android:title="Delete" />
</menu>
Code
I'm using registerForContextMenu(getListView()) so I can handle the view and used:
#Override
public void onCreateContextMenu(ContextMenu menu , View v , ContextMenu.ContextMenuInfo menuInfo){
super.onCreateContextMenu(menu, v, menuInfo);
MenuInflater inflater = getActivity().getMenuInflater();
inflater.inflate(R.menu.notes_handler_menu, menu);
}
#Override
public boolean onContextItemSelected(MenuItem item){
AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();
if(item.getItemId() == R.id.menu_rename){
// do something
}
return false;
}
Didn't need to put all of the code since there's no problem. I only wanted to know if this is going to cause problems to earlier devices before API 11 or after.

--
my question is simple , is what I used enough for both api 8 and up ? or do I need to implement other methods ?

Sorry, I'm not thinking straight.
You have no code for a contextual action bar, based upon what you have posted. Hence, you will not see a contextual action bar. I don't even know if you have a regular action bar -- you probably do, but that would depend upon the definition of AppTheme.
Your code will bring up an old-style context menu.
Is this going to be a problem?
That depends on your definition of "problem". Using a context menu on API Level 15+ devices (i.e., the vast majority of Android devices in use) will look out of date to some people.

How to show option menu in android 4.2

I am trying to create menu option in my test application.
I am able to see the menu when I set the theme in manifest to just default (The menu shows up in the top). If I set the theme in manifest to NoTitleBar. I can't see the menu option?
I want to get the menu when I set theme "NoTitleBar" in manifest.
How to fix it?
Below are things that I have used in my test application:
with Manifest:
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#android:style/Theme.NoTitleBar" >
<activity
android:name="com.ssn.menuoptions.MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
And
Menu.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/menu_preferences"
android:title="Preferences" />
</menu>
Java file:
#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;
}
Is it possible to get something like this:
How do I make menu to show up down?
Thanks!

Add following code below Activity.setContentView();
setContentView(R.layout.activity_detail);
// set option menu if has no hardware menu key
boolean hasMenu = ViewConfiguration.get(this).hasPermanentMenuKey();
if(!hasMenu){
//getWindow().setFlags(0x08000000, 0x08000000);
try {
getWindow().addFlags(WindowManager.LayoutParams.class.getField("FLAG_NEEDS_MENU_KEY").getInt(null));
}
catch (NoSuchFieldException e) {
// Ignore since this field won't exist in most versions of Android
}
catch (IllegalAccessException e) {
Log.w("Optionmenus", "Could not access FLAG_NEEDS_MENU_KEY in addLegacyOverflowButton()", e);
}
}

If you don't want an action bar in your app, then you can just set up a button with this handler:
myButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) { openOptionsMenu(); }
});
Now myButton works like the menu key. This is an easy way to migrate a fullscreen app to 4.x, though longer term a more elegant solution should be sought.

Using the notitlebar theme removes the actionbar where the menu button is. You'd probably have to make a custom theme to have your menu in it.
If you're not doing anything about it, you can always at least use this attribute: android:showAsAction="Never" so that users with phones that have a menu button can pop up the menu with their button.

Add in Android Manifest android:targetSdkVersion="10"
<uses-sdk
android:targetSdkVersion="10" />

Open Option menu on device without hardware keys

In my app I want to use an activity without titelbar or actionbar. I solved this with:
<activity
android:name="com.cilenco.lockscreen.Position"
android:label="#string/title_activity_position"
android:theme="#android:style/Theme.Light.NoTitleBar" >
<intent-filter>
<action android:name="com.cilenco.lockscreen.Position" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
My problem now is that I have to use an option menu and if I run my app on a device without hardware keys I can not open the option menu. I thought I will the Button with 3 dots (Overflow menu) in the bar where the back and home key is but it is not visible. What can I do to open the option menu on devices without hardware keys?

There is a function openOptionsMenu() that you could call
manually in your activity when you want to open the menu.
public void openMenu()
{
openOptionsMenu();
}
Better:
if you want the 3 dot overflow button in the navigation bar
just create your optionsMenu as usual:
#Override
public boolean onCreateOptionsMenu(Menu menu)
{
//add your menu
}
#Override
public boolean onOptionsItemSelected(MenuItem item)
{
//select what happens when you click at an item
return true;
}
and make sure to set both minSdkVersion and targetSdkVersion to "10" or lower!
For example:
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="your.package.name">
<uses-sdk android:minsdkversion="4" android:targetsdkversion="10" />
</manifest>

I want to display Overflow menu..so plz Suggest me ..
Thanks in Advance..

NOTE: With this suggestion, I am not recommending using ForceOverFlow to any reader. This is simply listing a possibility of making it work (forcing it to work rather). To each his own. Some may want it and like it too. Others may not.
I am probably speculating, but perhaps, this may do it for you.
You can think of this a hack, but I used it before to force the Overflow menu in one of my apps earlier and it works.
try {
ViewConfiguration config = ViewConfiguration.get(MainPage.this);
Field menuKeyField = ViewConfiguration.class.getDeclaredField("sHasPermanentMenuKey");
if (menuKeyField != null) {
menuKeyField.setAccessible(true);
menuKeyField.setBoolean(config, false);
}
} catch (Exception e) {
e.printStackTrace();
}
Also, the second link by MisterSmith has a solution of sorts with my answer in it. Commonsware has put down some thought about forcing the OverFlow menu here: How To Control use of OverFlow Menu in ICS
EDIT: While typing out this suggestion, you added a comment. To respond to that, I would like to point out that Jake Wharton took out .ForceOverFlow themes. I haven't tried it with version 4.2.0, but with a custom theme, it just might work. If you absolutely must use ForceOverFlow, you might have to use an older version. Read my answer here: https://stackoverflow.com/a/13180285/450534. Something might just make it work.
EDIT 2: As pointed out by the OP in a comment, the Demos Sample APK, in fact, does ForceOverFlow the action bar in Action Modes. I have a feeling, after checking the relevant Java files on github, that the answer to that lies perhaps in 3 Java files.
The Activity ActionModes adds menu items in a very unconventional manner: https://github.com/JakeWharton/ActionBarSherlock/blob/master/samples/demos/src/com/actionbarsherlock/sample/demos/ActionModes.java (Line 53)
The ActionMode Java file in the ABS Library: https://github.com/JakeWharton/ActionBarSherlock/blob/master/library/src/com/actionbarsherlock/view/ActionMode.java
The MenuItem Java file again part of the ABS Library: https://github.com/JakeWharton/ActionBarSherlock/blob/master/library/src/com/actionbarsherlock/view/MenuItem.java
