If you are in landscape or portrait Android looks for the layout file in either the -port or -land directory first, if it&#39;s not found then it falls back to the default layout directory.

You can read about providing alternative resources [here][1]. There are many more options than just land and port.


  [1]: http://developer.android.com/guide/topics/resources/providing-resources.html

If you put `home.xml` in `layout-port` folder, when your device is in portrait orientation it will use the file: `layout-port/home.xml`. 

If you put `home.xml` in `layout-land` folder, when your device in landscape orientation it will use the file: `layout-land/home.xml`. 

Meaning for different orientation modes like portrait and landscape... we use two `home.xml` files; one in `layout-port` and the other in `layout-land`. If on the other hand you want to use the same layout file for both, you can just put `home.xml` in the `layout` folder and remove it from `layout-land` and `layout-port`.

 

Create folder in `res layout-land` or `layout-port`

**`layout-port:`** layout for widget that must change for portrait orientation

**`layout-land:`** layout for widget that must change for landscape orientation

what is the best way to extract a substring from a string in android?

Extract substring from a string

The pimp-my-library pattern allows me to seemingly add a method to a class by making available an implicit conversion from that class to one that implements the method.

Scala does not allow two such implicit conversions taking place, however, so I cannot got from `A` to `C` using an implicit `A` to `B` and another implicit `B` to `C`. Is there a way around this restriction?

I&#39;m not sure to have understood well the role played by the several Android `/res/layout` folders.

`layout`: general layouts

`layout-port`: layout for widget that must change for portrait orientation

`layout-land`: layout for widget that must change for landscape orientation

For example in the [Home][1] sample application, under `layout-port` and `layout-land` folders there is only one `home.xml` file.

Have I understood right?

Android layout folders: layout, layout-port, layout-land

I'm not sure to have understood well the role played by the several Android <code>/res/layout</code> folders.
<code>layout</code>: general layouts
<code>layout-port</code>: layout for widget that must change for portrait orientation
<code>layout-land</code>: layout for widget that must change for landscape orientation
For example in the <a href="http://developer.android.com/resources/samples/Home/index.html" target="_blank" rel="noopener noreferrer">Home</a> sample application, under <code>layout-port</code> and <code>layout-land</code> folders there is only one <code>home.xml</code> file.

I&#39;m using the SQLite with Android, and I want to know the best way to get the generated id of the row I inserted.

A solution I think makes a search after include, but it doesn&#39;t look the best way.

I have an array of objects.

Is it possible to make a new array that is a copy of this array, but in reverse order?
I was looking for something like this. 

    // my array
    ArrayList&lt;Element&gt; mElements = new ArrayList&lt;Element&gt;();
    // new array
    ArrayList&lt;Element&gt; tempElements = mElements;
    
    tempElements.reverse(); // something to reverse the order of the array

I want to make a TextView that is collapsable by user&#39;s touch.
When the TextView collapsed, I set `textView.setMaxLines(4);`.
How to I clear this state in my expand method?
I can only think of call `setMaxLines()` with a value large number like **10000**.

Are there better ways to implement this?

Reset Android textview maxlines

I want to show a button under a `ListView`. Problem is, if the `ListView` gets extended (items added...), the button is pushed out of the screen. 

I tried a `LinearLayout` with weights (as suggested in https://stackoverflow.com/questions/4054567/android-why-is-there-no-maxheight-for-a-view), but either I got the weights wrong or it simply didn&#39;t work. 

Also, I found somewhere the hint to use a `RelativeLayout`. The `ListView` would then be set above the button with the `android:layout_above` param. 

Problem with this is that I don&#39;t know how to position the button afterwards. In the example I found, the View below the `ListView` was adjusted using `android:layout_alignParentBottom`, but I don&#39;t want my button to cling to the bottom of the screen. 

Any ideas apart from using setHeight-method and some calculating of the required space?

Edit:
**I got a lot of useful answers.**

 - bigstone&#39;s &amp; user639183&#39;s solution *almost* worked perfectly. However, I had to add an extra padding/margin to the bottom of the button, as it still would be pushed half way out of the screen (but then stopped)

 - Adinia&#39;s answer with the relative layout only is fine if you want the button fixed to the bottom of the screen. It&#39;s not what I intended but still might be useful for others.

 - AngeloS&#39;s solution was the one I chose at the end as it just created the effects I wanted. However, I made two minor changes to the `LinearLayout` around the button: 

    - First, as I didn&#39;t want to have any absolute values in my layout, I changed `android:layout_height=&quot;45px&quot;` to `wrap_content`, which works just fine as well. 

    - Second, as I wanted the button to be centered horizontally, which is only supported by vertical `LinearLayout`, I changed android:orientation=&quot;horizontal&quot; to &quot;vertical&quot;. 
 
   AngeloS also stated in his initial post that he was not sure if the `android:layout_weight=&quot;0.1&quot;` param in the `LinearLayout` around the `ListView` had any effect; I just tried and it actually does! Without, the button gets pushed out of the screen again.

Limit height of ListView on Android

Is such a thing possible using CSS and two inline-block (or whatever) DIV tags instead of using a table?

The table version is this (borders added so you can see it):

    &lt;!DOCTYPE html PUBLIC &quot;-//W3C//DTD XHTML 1.0 Transitional//EN&quot; &quot;http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd&quot;&gt;
    &lt;html xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;
    &lt;head&gt;&lt;/head&gt;
    &lt;body&gt;
    &lt;table style=&quot;width:100%;&quot;&gt;
    &lt;tr&gt;
    &lt;td style=&quot;border:1px solid black;width:100px;height:10px;&quot;&gt;&lt;/td&gt;
    &lt;td style=&quot;border:1px solid black;height:10px;&quot;&gt;&lt;/td&gt;
    &lt;/tr&gt;
    &lt;/table&gt;
    &lt;/body&gt;
    &lt;/html&gt;
    
It produces a left column with a **FIXED WIDTH** (not a percentage width), and a right column that expands to fill **THE REMAINING SPACE** on the line.  Sounds pretty simple, right?  Furthermore, since nothing is &quot;floated&quot;, the parent container&#39;s height properly expands to encompass the height of the content.

**--BEGIN RANT--**&lt;br&gt;
I&#39;ve seen the &quot;clear fix&quot; and &quot;holy grail&quot; implementations for multi-column layouts with fixed-width side column, and they suck and they&#39;re complicated.  They reverse the order of elements, they use percentage widths, or they use floats, negative margins, and the relationship between the &quot;left&quot;, &quot;right&quot;, and &quot;margin&quot; attributes are complex.  Furthermore, the layouts are sub-pixel sensitive so that adding even a single pixel of borders, padding, or margins will break the whole layout, and send entire columns wrapping to the next line.  For example, rounding errors are a problem even if you try to do something simple, like put 4 elements on a line, with each one&#39;s width set to 25%.&lt;br&gt;
**--END RANT--**

I&#39;ve tried using &quot;inline-block&quot; and &quot;white-space:nowrap;&quot;, but the problem is I just can&#39;t get the 2nd element to fill the **remaining** space on the line.  Setting the width to something like &quot;width:100%-(LeftColumWidth)px&quot; will work in some cases, but performing a calculation in a width property is not really supported.

How to make an inline-block element fill the remainder of the line?

How can I put 2 buttons side by side, so that they occupy all the width, with a little space between them?

I thought a horiz linear layout, with 2 sub linear layouts set to match parent and weight 1, each of them containing the button. Is there a simpler way? can this be accomplished with relative layouts?

I want to make an HTML page containing a single SVG image that automatically scales to fit the browser window, without any scrolling and while preserving its aspect ratio.

For example, at the moment I have a 1024x768 SVG image; if the browser viewport is 1980x1000 then I want the image to display at 1333x1000 (fill vertically, centred horizontally).  If the browser was 800x1000 then I want it to display at 800x600 (fill horizontally, centred vertically).

Currently I have it defined like so:

    &lt;body style=&quot;height: 100%&quot;&gt;
      &lt;div id=&quot;content&quot; style=&quot;width: 100%; height: 100%&quot;&gt;
        &lt;svg xmlns=&quot;http://www.w3.org/2000/svg&quot; version=&quot;1.1&quot;
             width=&quot;100%&quot; height=&quot;100%&quot;
             viewBox=&quot;0 0 1024 768&quot;
             preserveAspectRatio=&quot;xMidYMid meet&quot;&gt;
          ...
        &lt;/svg&gt;
      &lt;/div&gt;
    &lt;/body&gt;

However this is scaling up to the full width of the browser (for a wide but short window) and producing vertical scrolling, which isn&#39;t what I want.

What am I missing?

I have a `TextView` which I want to pin at the bottom of a landscape activity that is using `LinearLayout` with vertically arranged elements.  

I have set `android:gravity=&quot;bottom&quot;` on the text view, but it still likes to be just below the last element of the `LinearLayout` exactly what I do not want it to do.  

Any suggestions?
