You need to change the code style in `Project Settings`

    File -&gt; Settings -&gt; (Project Settings) -&gt; Code Style -&gt; Java -&gt; Wrapping and Brances

Change the `Braces Placement` for `Class` and `Method` declaration to `Next Line`

(Or, on a Mac, do the same thing in `Preferences`)

I am new to angularjs. How can I detect userAgent in angularjs. Is it possible to use that in controller? Tried something like below but no luck!


      var browserVersion = int((/msie (\d+)/.exec(lowercase(navigator.userAgent)) || [])[1]);

I recently started to use Android Studio. It uses this style of braces by default: 

    public void scanFile(String filePath) {
    
    }

The code I need to submit requires to be styled as follows: 

    public void scanFile(String filePath) 
    {
    
    }

Where can I find a setting for this?

I have a Sherlock Fragment Activity in which there are 3 Fragments.

Fragment A, Fragment B, Fragment C are three fragments. I want to show a done option menu in Fragment B only.


And the activity is started with Fragment A. When Fragment B is selected done button is added.
	

    @Override
    public void onCreate(Bundle savedInstanceState) {
    	super.onCreate(savedInstanceState);
        setHasOptionsMenu(true);
    }
    
    @Override
    public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    	if(!menusInflated){
    		inflater.inflate(R.menu.security, menu);
    		menusInflated=true;
    	}
    
    	super.onCreateOptionsMenu(menu, inflater);
    }

When I again start Fragment A I want to options Menu DONE (which was set at Fragment B) for this I am doing like this

    setHasOptionsMenu(false);
    MenuItem item = (MenuItem) menu.findItem(R.id.done_item);
    item.setVisible(false);

But this is not hiding at all, also it is giving NullPointerException when Activity if first started with Fragment A.


Please let me know what is the problem.

i am setting an actionLayout on a menu item and setting background color and image, but it&#39;s not respected. in my activity, i have:

    getMenuInflater().inflate(R.menu.submit_action, menu);

my submit_action is:

    &lt;menu xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
        xmlns:app=&quot;http://schemas.android.com/apk/res-auto&quot;&gt;
        &lt;item android:id=&quot;@+id/action_submit&quot;
            android:actionLayout=&quot;@layout/check&quot;
            app:showAsAction=&quot;always&quot;  /&gt;
    &lt;/menu&gt;

my check layout is

    &lt;RelativeLayout xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
        style=&quot;?android:attr/actionButtonStyle&quot;
        android:layout_width=&quot;fill_parent&quot;
        android:layout_height=&quot;fill_parent&quot;
        android:background=&quot;#e8e8e8&quot;
        android:clickable=&quot;true&quot;
        android:contentDescription=&quot;lol&quot; &gt;
    
        &lt;ImageView
            android:layout_width=&quot;wrap_content&quot;
            android:layout_height=&quot;wrap_content&quot;
            android:contentDescription=&quot;@null&quot;
            android:scaleType=&quot;centerInside&quot;
            android:src=&quot;@drawable/ic_action_tick&quot; /&gt;
    
    &lt;/RelativeLayout&gt;


but even with all of this setup, this is how the action bar appears, not showing my menuitem at all (but it&#39;s there, because it responds to the click, but doesn&#39;t appear):

After having imported an Eclipse project into Android Studio, I see two `build.gradle` files:

    1 - &lt;PROJECT_ROOT&gt;\build.gradle
    2 - &lt;PROJECT_ROOT&gt;\app\build.gradle

The first version is shorter, the second version contains definitions for `compileSdkVersion`, etc.

What is the purpose behind having two separate files?  Are there separate build tasks?

Right now I am using the Darcula theme.  I want to change the default font to something else.  I go into `Editor &gt; Colors &amp; Fonts &gt; Font` but all the options are greyed out.  For `Editor Font` it shows `Show only monospaced fonts` as checked with `Primary font` as Monospaced, but neither of these can be changed.  I tried changing the font under `Appearance` but that just changes the font used around AS and not inside the editor.

I just moved to Android Studio from Eclipse, and I found that it always shows &quot;fetching documentation&quot; when I use quick documentation (&lt;kbd&gt;Ctrl&lt;/kbd&gt;+&lt;kbd&gt;Q&lt;/kbd&gt;).

How can I solve this problem?
I downloaded the documentation for API 19, and the problem persists.
