You can create a Drawable or Bitmap from a string path like this:

    String pathName = &quot;/path/to/file/xxx.jpg&quot;; 
    Drawable d = Drawable.createFromPath(pathName);

For a Bitmap:
    
    String pathName = &quot;/path/to/file/xxx.jpg&quot;;
    Bitmap b = BitmapFactory.decodeFile(pathName);

This code was generated for me after added entity framework code-first for SQL Server CE using NuGet. They did no changes to any other file. The file `SQLCEEntityFramework.cs` was created and placed in `App_Start` folder.

Does this mean it automatically gets executed or something? The same thing happened when I added Ninject for MVC 3. No code was added to the `global.ascx` file so I have no idea if its plug and play or I have to configure something.

I&#39;m just wondering if there is any significant difference between an `ImageView` that&#39;s set to be clickable, compared with an `ImageButton`?  

Is there any reason for using one over the other? Is there any restriction on the drawable for an `ImageButton` that leaves `ImageView` as the only possible option?  

Will I possibly lose any functionality of a button if I opt for a clickable `ImageView` over `ImageButton`?

I want to completely hide the groupIndicator in a custom ExpandableListView.

The example provided [here](https://stackoverflow.com/questions/4145090/expandablelistview-hide-indicator-for-groups-with-no-children) did not seem to work.

It suggests making a selector and using expList.setGroupIndicator(selector), which I replicated:

    &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
    &lt;selector xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot; android:id=&quot;@+id/empty_icon&quot;&gt;
        &lt;item android:state_empty=&quot;true&quot; android:drawable=&quot;@android:color/transparent&quot;/&gt;
        &lt;item android:state_expanded=&quot;true&quot; android:drawable=&quot;@android:color/transparent&quot; /&gt;
        &lt;item android:drawable=&quot;@android:color/transparent&quot; /&gt;
    &lt;/selector&gt;

This gives the following error&lt;br&gt;`ERROR/AndroidRuntime(10675): Caused by: android.content.res.Resources$NotFoundException: Resource is not a Drawable (color or path): TypedValue{t=0x12/d=0x0 a=2 r=0x7f0b0013}`

The same is given by the similar suggestion of using android:id/empty in place of color/transparent.

How can I completely hide the group indicator?


Edit: As it turns out, that code DOES work... if you put it in the drawable resource folder instead of layout.

I have a view which is used as an item in a `ListView`. In my custom adapter, I change the background of the view using `View.setBackgroundResource()` depending on the item&#39;s position in the list. (I have separate assets for the first and last items in the list.)

This sets the correct background image as expected, but it has the nasty side-effect that  all the padding I&#39;d set in the XML definition of the view is completely ignored.

(If I set the background drawable in the XML, and don&#39;t try to vary it at runtime in the adapter, the padding all works fine.)

How can I alter the background image, and retain the padding? Is this a bug?

**EDIT** it seems someone else has found the same problem here: https://stackoverflow.com/questions/2886140/does-change-the-background-change-the-padding-of-a-linear-layout

setBackgroundResource() discards my XML layout attributes

I have a drawable that i use as a Background for a LinearLayout. I would like to change the color of this Shape in runtime. I have tried using several methods.. but none work.

I&#39;ve followed the approach described here: http://www.anddev.org/android-2d-3d-graphics-opengl-problems-f55/change-shape-drawable-solid-color-t16798.html

But have the same problem... it doesnt crashes.. but the color doesnt change!

    &lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt;
    &lt;shape xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;&gt;
    	&lt;solid android:color=&quot;#00A6C1&quot; /&gt;
    	&lt;corners android:radius=&quot;@dimen/square_corners&quot; /&gt;
    &lt;/shape&gt;



Snippet of code:

    GradientDrawable drawable = (GradientDrawable) activity.getResources().getDrawable(R.drawable.blue_square_shape);
        
    
    int color = ((Application) getApplication()).getColor();
    drawable.setColor(color);
        
    block.findViewById(R.id.blockSquare).setBackgroundDrawable(drawable);
    
    findViewById(R.id.blockSquare).postInvalidate();


Any clue? I&#39;ve passed the whole day googling... and it&#39;s getting pretty annoying...



**UPDATE:**

When i try to do the same to this Shape:

    &lt;shape xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
    	android:id=&quot;@+id/shape&quot; android:shape=&quot;rectangle&quot;&gt;
    	&lt;gradient android:startColor=&quot;#1FBCCF&quot; android:endColor=&quot;#06A4C1&quot;
    		android:angle=&quot;270&quot; /&gt;
    	&lt;corners android:topLeftRadius=&quot;@dimen/footer_corners&quot;
    		android:topRightRadius=&quot;@dimen/footer_corners&quot; /&gt;
    &lt;/shape&gt;

The color turns to black... what i guess tells it can be changed...

I am adding a couple of sample items in my application so it doesn&#39;t look so empty when the user look at it the first time. The list with the sample items should have an image and the image I am going to use is already stored in the /res/drawable-folder of the application. 

Since I already have a method that load the items images from a URI i&#39;d like to get the URI to the /res/drawable/myImage.jpg but I don&#39;t seem to be able to get it right. 

The flow is as follows:
Create item with string that represents the URI of the image.
Send list of items to an List 
The list loads the image in a background task by converting the string to URL and then run url.openStream();

I have tried a few options for the URI without any success. 
&quot;android.resource://.....&quot; says unknow protocoll
&quot;file://&quot; file not found

So right now I&#39;m a little bit lost about how to fix this..



Get the URI of an image stored in drawable

I need to get a Drawable object to display on an image button. Is there a way to use the code below (or something like it) to get an object from the android.R.drawable.* package?

for example if drawableId was android.R.drawable.ic_delete

    mContext.getResources().getDrawable(drawableId)

Until now I have not been specifying a MongoDB data directory and have had only one 30 GB primary partition.

I just ran out of space and added a new hard disk. How can I transfer my data (that is apparently in `/var/lib/mongodb/`) and configure MongoDB so that everything runs off of the new disk without affecting my existing installation?

Changing MongoDB data store directory

I need to get the last part of current directory, for example  from `/Users/smcho/filegen_from_directory/AIRPassthrough`, I need to get `AIRPassthrough`. 

With python, I can get it with this code.

    import os.path
    
    path = &quot;/Users/smcho/filegen_from_directory/AIRPassthrough&quot;
    print os.path.split(path)[-1]

Or

    print os.path.basename(path)

How can I do the same thing with C#?

## ADDED
With the help from the answerers, I found what I needed.

    using System.Linq;
    string fullPath = Path.GetFullPath(fullPath).TrimEnd(Path.DirectorySeparatorChar);
    string projectName  = fullPath.Split(Path.DirectorySeparatorChar).Last();

or 

    string fullPath = Path.GetFullPath(fullPath).TrimEnd(Path.DirectorySeparatorChar);
    string projectName = Path.GetFileName(fullPath);

Does C++ have any equivalent to python&#39;s function `os.path.join`? Basically, I&#39;m looking for something that combines two (or more) parts of a file path so that you don&#39;t have to worry about making sure the two parts fit together perfectly. If it&#39;s in Qt, that would be cool too.

Basically I spent an hour debugging some code and at least part of it was because `root + filename` had to be `root/ + filename`, and I&#39;m looking to avoid that in the future.

How to build a full path string (safely) from separate strings?

I&#39;m building a path string in PHP. I need it to work across platforms (i.e., Linux, Windows, OS X). 
I&#39;m doing this:

    $path = $someDirectory.&#39;/&#39;.$someFile;

Assume `$someDirectory` and `$someFile` are formatted correctly at run-time on the various platforms. This works beautifully on Linux and OS X, but not on Windows. The issue is the `/` character, which I thought would work for Windows.

Is there a PHP function or some other trick to switch this to `\` at runtime on Windows?

&lt;b&gt;EDIT:&lt;/b&gt; Just to be clear, the resultant string is 

    c:\Program Files (x86)\Sitefusion\Sitefusion.org\Defaults\pref/user.preferences

on Windows. Obviously the mix of slashes confuses Windows.

How to get a platform independent directory separator in PHP?

I run R on Windows, and have a csv file on the Desktop. I load it as follows,

    x&lt;-read.csv(&quot;C:\Users\surfcat\Desktop\2006_dissimilarity.csv&quot;,header=TRUE)


but the R gives the following error message

&gt; Error: &#39;\U&#39; used without hex digits in character string starting &quot;C:\U&quot;

So what&#39;s the correct way to load this file. I am using Vista
