Android: Hide 3 dots from Navigation view header at right - android

How to hide 3 dots from Navigation header which comes in the right of header? This could be repeated question. I found few similar questions and their answers but they were for older version of Android. I am using Android sdk 21.
Any idea how to hide that 3 dot button?

Just Remove Override Method like this
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.search_and_add, menu);
return true;
}
This Override Method is responsible to for creating three dote as you mention it's really OptionMenu. If you don't want it, don't override onCreateOptionsMenumethod.
Alternative
Don't Inflate the menu xml. Just block the line like this
//getMenuInflater().inflate(R.menu.search_and_add, menu);
other code can remain same. No problem at all..

Those "3 Dots" are the "Overflow" menu, and is created when you establish a menu using a file in the menu resources directory.
If you have buttons or functionality you are wanting to expose via you action bar, you will need to have the overflow buttons (or instead, you can choose to have your buttons exposed at the top level inside the Action bar.
If you really don't want a menu, get rid of the menu.xml file describing this menu, and then get rid of the onCreateOptionsMenu() from your Activity.
Here are the official docs, which describe how this works.

I think you are speaking about the options menu, to get rid of it remove the override of the method onCreateOptionsMenu

In your menu folder the xmlfile that is used by your activity, change the app:showAsAction="never" to app:showAsAction="always" or some other you can see the options that are availabe by pressing ctrl+space.
Or else to get rid of it completely just remove the whole code and it's corresponding usages.

Moving options menu to another view

I am trying to display the options menu in another place but the ActionBar, is it is hidden.
I have no clue on how to do it nor I find any function to do such things.
I am using Theme.Light.NoTitleBar as theme/style, but still I'd like to have the menu somewhere else, be it a View or a Layout.
Does anyone have any clue?
You would need to use Android support library , which would enable you to use Action Bar in Android Version 11.0 and above. You would also require to use Theme.Holo.Light.DarkActionBar as your application theme to make action bar visible.
After you do this , you may create menu xml file ad inflate it in onCreateOptionsMenu() function , and you can then access Action Bar like this : getActionBar() in your activity.

Is it possible to have a action bar menu using the appcompat library?

recently I've switched from the regular action bar implementation to the recently released appcompat implementation. My app made heavy use of the action bar to provide functionality. Since switching, on older spots
APIs (less than 11) don't have any menu items. And newer APIs do, but they don't show the image like configured (if room|withText). Has anyone else experienced this or came up with any solutions?
I found out what was up, when using the appcompat library. You can create your menu just like normal.
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
But, in your menu xml files, add a xmlns:app attribute to the menu tag, like so:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto" >
then, in each of your menu items, where you usually specify the "showAs" style (ifRoom, withText, etc.), include this alternative line alongside the regular one:
app:showAsAction="ifRoom|withText"
android:showAsAction="ifRoom|withText"
After this, your menus will show correctly on both current and old APIs. I got this information from here.
If there is a physical "Menu" button on device, it will show the contextual menu. If not, the menu item will be added to the ActionBar.

What does onPrepareOptionsMenu do?

I want to make Option Menu for Android, I have visit this site. In their script, I found onPrepareOptionsMenu, I try to compile and run using Android 2.3.3 compiler with and without onPrepareOptionsMenu, both works, but I didn't see any difference.
public boolean onCreateOptionsMenu(Menu menu){
//code here
}
public boolean onOptionsItemSelected(MenuItem item){
//code here
}
public boolean onPrepareOptionsMenu(Menu menu){
//code here
}
What is actually onPrepareOptionsMenu method do? Is that method important? Could I just delete the method?
Addition
Oh, I also hear about Action Bar in Android 3.0, it says that Action Bar is the alternative way for make Option Menu, and it using onPrepareOptionsMenu. Is that right?
Thank you...
Take a look in the API:
Prepare the Screen's standard options menu to be displayed. This is called right before the menu is shown, every time it is shown. You can use this method to efficiently enable/disable items or otherwise dynamically modify the contents.
If you want to alter the menu before it's shown to the user, you can put code to do that into onPrepareOptionsMenu. I've used that dynamically to disable some menu options in some circumstances.
As an example of when one might want to disable a menu option, I had an app where there was a way of specifying a destination. One of my menu options was to calculate a route to the destination. However, if a destination wasn't specified, that option didn't apply, so I used onPrepareOptionsMenu to disable that menu option when it wasn't applicable.
From Android 3.0 and beyond, there's the ActionBar, which is a menu bar. The most important items go into the ActionBar itself, but then there's an overflow for when there's not enough room on the action bar. One can specify that menu items should always be in the overflow menu and never on the action bar itself. On some devices, the action bar overflow corresponds to the permanent menu button on the device, whereas on other devices which don't have a menu button the overflow menu is seen on the right hand side of the action bar as three vertical dots.
onCreateOptionsMenu is called once, when your activity is first created. If it returns false, no option menu is shown and onPrepareOptionsMenu is never called.
If onCreateOptionsMenu returns true, onPrepareOptionsMenu is also called before the activity is displayed, and also every time the options menu is invalidated. Use onPrepareOptionsMenu if you need to enable/disable, show/hide, or add/remove items after creating it.
If your menu does not change, use onCreateOptionsMenu.
example
#Override
public void onPrepareOptionsMenu(#NonNull Menu menu) {
super.onPrepareOptionsMenu(menu);
if(!URLUtil.isValidUrl(news.geturl())){
menu.findItem(R.id.share).setVisible(false);
}
}

Two level Sliding menu in android application

I want to use facebook like sliding menu, but with a menu and submenu. If any item in the menu is clicked a sub menu must appear and both the parent menu and the sub menu must be displayed. Is there any library available for this that could be used even for APIs below 16. I have searched a lot for implementing submenus, but not successful. Pls help...
Your question is not very clear to me. But with what I feel is use ActionBarSherlock and define both left fragment and right fragment in xml and use refer it in the MainActivity. I hope I helped. Is this what you want?
