You could create a <code>values-&lt;config&gt;</code> directory for each of your supported configurations. Inside of each of those directories, create a <code>strings.xml</code> with a single <code>selected_configuration</code> string which describes the current configuration. At runtime, fetch the string using the standard <code>getString</code> method, which will do the configuration resolution for you and return the correct string for the configuration.

You can set a different <a href="http://developer.android.com/reference/android/view/View.html#attr_android%3atag"><code>android:tag</code></a> attribute on the views in each different resource file, and read the tag back at runtime with <a href="http://developer.android.com/reference/android/view/View.html#getTag%28%29"><code>View.getTag()</code></a>.

layout-xlarge/my_act.xml

I am assuming you are using <code>setContentView(int resID)</code> to set the content of your activities.

<hr>

METHOD 1 (This is my answer)

Now in all your layouts make sure that the root view always has the right tag:

example:

<code>layout-xlarge/main.xml</code>:

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:tag="xlarge-landscape"
 android:layout_width="fill_parent"
 android:layout_height="fill_parent"
 android:orientation="vertical" &gt;

 &lt;TextView
 android:layout_width="fill_parent"
 android:layout_height="wrap_content"
 android:text="@string/hello" /&gt;

&lt;/LinearLayout&gt;
</code></pre>

<code>layout-small/main.xml</code>:

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:tag="small"
 android:layout_width="fill_parent"
 android:layout_height="fill_parent"
 android:orientation="vertical" &gt;

 &lt;TextView
 android:layout_width="fill_parent"
 android:layout_height="wrap_content"
 android:text="@string/hello" /&gt;

&lt;/LinearLayout&gt;
</code></pre>

Now let your activities extend this activity:

<pre><code>package shush.android.screendetection;

import android.app.Activity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class SkeletonActivity extends Activity {

 protected String resourceType;

 @Override
 public void setContentView(int layoutResID) {
 LayoutInflater inflater = getLayoutInflater();
 View view = inflater.inflate(layoutResID, null);
 resourceType = (String)view.getTag();
 super.setContentView(view);
 }
}
</code></pre>

In this case, you can use the <code>resourceType</code> to know what is the resource identifier used.

<hr>

METHOD 2 (This was my answer but before posting I thought of the better one)

Now in all your layouts make sure that the root view always has the right tag:

example:

<code>layout-xlarge/main.xml</code>:

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:tag="xlarge-landscape"
 android:layout_width="fill_parent"
 android:layout_height="fill_parent"
 android:orientation="vertical" &gt;

 &lt;TextView
 android:layout_width="fill_parent"
 android:layout_height="wrap_content"
 android:text="@string/hello" /&gt;

&lt;/LinearLayout&gt;
</code></pre>

<code>layout-small/main.xml</code>:

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:tag="small"
 android:layout_width="fill_parent"
 android:layout_height="fill_parent"
 android:orientation="vertical" &gt;

 &lt;TextView
 android:layout_width="fill_parent"
 android:layout_height="wrap_content"
 android:text="@string/hello" /&gt;

&lt;/LinearLayout&gt;
</code></pre>

Now let your activities extend this activity:

<pre><code>package shush.android.screendetection;

import android.app.Activity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class SkeletonActivity extends Activity {

 @Override
 public void setContentView(int layoutResID) {
 LayoutInflater inflater = getLayoutInflater();
 View view = inflater.inflate(layoutResID, null);
 fix(view, view.getTag());
 super.setContentView(view);
 }

 private void fix(View child, Object tag) {
 if (child == null)
 return;

 if (child instanceof ViewGroup) {
 fix((ViewGroup) child, tag);
 }
 else if (child != null) {
 child.setTag(tag);
 }
 }

 private void fix(ViewGroup parent, Object tag) {
 for (int i = 0; i &lt; parent.getChildCount(); i++) {
 View child = parent.getChildAt(i);
 if (child instanceof ViewGroup) {
 fix((ViewGroup) child, tag);
 } else {
 fix(child, tag);
 }
 }
 }
}
</code></pre>

In this case all your views in your hierarchy will have the same tag.

You can get info about screen orientation and size from <code>Resources</code> object. From there you can understand which layout is used.

<code>getResources().getConfiguration().orientation;</code> - returns either <code>Configuration.ORIENTATION_PORTRAIT</code> or <code>Configuration.ORIENTATION_LANDSCAPE</code>.

<code>int size = getResources().getConfiguration().screenLayout;</code> - returns mask of screen size. You can test against Small, Normal, Large, xLarge sizes. For example:

<pre><code>if ((size &amp; Configuration.SCREENLAYOUT_SIZE_XLARGE)==Configuration.SCREENLAYOUT_SIZE_XLARGE)
</code></pre>

I dont know the exact way to find it. But we can find it in different way.

Add one textview in all the layouts.(visibility hidden). Assign values like xlarge, land, xlarge-land accordingly.

In program, get the value from textview. Somehow we can get to know like this.

Your question is as same as this <a href="https://stackoverflow.com/q/11315111/1008278">How to get layout xml file path?</a> You can add a Hidden Text View with corresponding Folder names in the xml
Get the String in the text view by

<pre><code>TextView path = (TextView)findViewbyid(R.id.hiddentextview); 
 String s = path.gettext().tostring();
</code></pre>

Make sure that all the id's of the text view are same. 

Example

<pre><code>if your xml is in `normal-mdpi` in hidden textview hard code `normal-mdpi`
if your xml is in `large-mdpi` in hidden textview hard code `large-mdpi`
</code></pre>

Assume I have an activity with three different layouts in different resource folders. For example:

<blockquote>
 <code>layout-land/my_act.xml</code> 
 <code>layout-xlarge/my_act.xml</code> 
 <code>layout-xlarge-land/my_act.xml</code> 
</blockquote>

In different devices and different positions one of them is selected by Android. How can I find out which one is selected programmatically?

Does Android have any API that returns these layouts to the program?

Edit: <a href="https://stackoverflow.com/a/11205220/779408">Graham Borland's solution</a> has a problem in some situations that I mentioned in the comments.

How can I detect which layout is selected by Android in my application?

Android

假设我有一个活动，在不同的资源文件夹中有三个不同的布局。例如： layout-land/my_act.xmllayout-xlarge/my_act.xmllayout-xlarge-land/my_act.xml在不同的设备和不同的位置，其中一个是由Android选择的。我怎样才能知道哪一个是以编程方式选中的？Android是否有任何API可以将这些布局返回给程序？编辑：在我在评论中提到的某些情
