I think, more way is possible.
But sometimes, I using this solution. (full global):

<pre><code> import android.content.Context;

 import &lt;your package&gt;.R;

 public class XmlVar {

 private XmlVar() {

 private static String _write_success;

 public static String write_success() {

 public static void Init(Context c) {
 _write_success = c.getResources().getString(R.string.write_success);
 }
 }
//After activity created:

XmlVar.Init(cont);
//And use everywhere
XmlVar.write_success();

The Singleton:

<pre><code>package com.domain.packagename;

import android.content.Context;

/**
 * Created by Versa on 10.09.15.
 */
public class ApplicationContextSingleton {
 private static PrefsContextSingleton mInstance;
 private Context context;

 public static ApplicationContextSingleton getInstance() {
 if (mInstance == null) mInstance = getSync();
 return mInstance;
 }

 private static synchronized ApplicationContextSingleton getSync() {
 if (mInstance == null) mInstance = new PrefsContextSingleton();
 return mInstance;
 }

 public void initialize(Context context) {
 this.context = context;
 }

 public Context getApplicationContext() {
 return context;
 }

}
</code></pre>

Initialize the Singleton in your <code>Application</code> subclass:

<pre><code>package com.domain.packagename;

import android.app.Application;

/**
 * Created by Versa on 25.08.15.
 */
public class mApplication extends Application {

 @Override
 public void onCreate() {
 super.onCreate();
 ApplicationContextSingleton.getInstance().initialize(this);
 }
}
</code></pre>

If I´m not wrong, this gives you a hook to applicationContext everywhere, call it with <code>ApplicationContextSingleton.getInstance.getApplicationContext();</code>
You shouldn´t need to clear this at any point, as when application closes, this goes with it anyway.

Remember to update <code>AndroidManifest.xml</code> to use this <code>Application</code> subclass:

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;

&lt;manifest
 xmlns:android="http://schemas.android.com/apk/res/android"
 package="com.domain.packagename"
 &gt;

&lt;application
 android:allowBackup="true"
 android:name=".mApplication" &lt;!-- This is the important line --&gt;
 android:label="@string/app_name"
 android:theme="@style/AppTheme"
 android:icon="@drawable/app_icon"
 &gt;
</code></pre>

Now you should be able to use ApplicationContextSingleton.getInstance().getApplicationContext().getResources() from anywhere, also the very few places where application subclasses can´t.

Please let me know if you see anything wrong here, thank you. :)

Another solution:

If you have a static subclass in a non-static outer class, you can access the resources from within the subclass via static variables in the outer class, which you initialise on creation of the outer class. Like

<pre><code>public class Outerclass {

 static String resource1

 public onCreate() {
 resource1 = getString(R.string.text);
 }

 public static class Innerclass {

 public StringGetter (int num) {
 return resource1; 
 }
 }
}
</code></pre>

I used it for the getPageTitle(int position) Function of the static FragmentPagerAdapter within my FragmentActivity which is useful because of I8N.

There is also another possibilty. I load OpenGl shaders from resources like this:

<pre><code>static private String vertexShaderCode;
static private String fragmentShaderCode;

static {
 vertexShaderCode = readResourceAsString("/res/raw/vertex_shader.glsl");
 fragmentShaderCode = readResourceAsString("/res/raw/fragment_shader.glsl");
}

private static String readResourceAsString(String path) {
 Exception innerException;
 Class&lt;? extends FloorPlanRenderer&gt; aClass = FloorPlanRenderer.class;
 InputStream inputStream = aClass.getResourceAsStream(path);

 byte[] bytes;
 try {
 bytes = new byte[inputStream.available()];
 inputStream.read(bytes);
 return new String(bytes);
 } catch (IOException e) {
 e.printStackTrace();
 innerException = e;
 }
 throw new RuntimeException("Cannot load shader code from resources.", innerException);
}
</code></pre>

As you can see, you can access any resource in path <code>/res/...</code>
Change <code>aClass</code> to your class. This also how I load resources in tests (androidTests)

My Kotlin solution is to use a static Application context:

<pre><code>class App : Application() {
 companion object {
 lateinit var instance: App private set
 }

 override fun onCreate() {
 super.onCreate()
 instance = this
 }
}
</code></pre>

And the Strings class, that I use everywhere:

<pre><code>object Strings {
 fun get(@StringRes stringRes: Int, vararg formatArgs: Any = emptyArray()): String {
 return App.instance.getString(stringRes, *formatArgs)
 }
}
</code></pre>

So you can have a clean way of getting resource strings

<pre><code>Strings.get(R.string.some_string)
Strings.get(R.string.some_string_with_arguments, "Some argument")
</code></pre>

Here is an alternative, slightly different, approach that you may try.
You could subclass the <code>Application</code> class like what other solutions mentioned, and store a static reference to an instance of <code>Resources</code>.
Create an application class and initialise the <code>Resources</code> variable in the <code>onCreate</code> method. This will be called when your app starts. We can use <code>WeakReference</code> here to prevent memory leaks that might happen as a result of storing this instance as a static variable(although it is very unlikely to happen)
<pre class="lang-java prettyprint-override"><code>public class App extends Application {
 private static WeakReference&lt;Resources&gt; res;
</code></pre>
Since you mentioned that you only want to retrieve strings from the xml resource declaration, there is no need to expose this resource variable to other classes, for encapsulation of the resources instance and to prevent it from leaking out. Hence, you may store the reference as a private variable.
Remember to initialise this variable in <code>onCreate</code>:
<pre class="lang-java prettyprint-override"><code>@Override 
public void onCreate() { 
 super.onCreate(); 
 res = new WeakReference&lt;&gt;(getResources());
}
</code></pre>
We also need to declare the application's <code>android:name</code> as <code>.App</code>(or any other name you set it to) in <code>AndroidManifest.xml</code> under the <code>application</code> tag.
<pre class="lang-xml prettyprint-override"><code>&lt;application android:name=&quot;.App&quot;
........... other attributes here ...........
</code></pre>
Another way of retrieving the string resource is not by using the <code>Resources</code> instance in other classes(or the <code>Context</code> instance), but to get the <code>App</code> class to get this for you in a static method. This keeps the instance encapsulated/private.
You can use a static method in your <code>App</code> class to retrieve these values(e.g. <code>getStringGlobal</code>, just do not call it <code>getString</code> as it will conflict with the default method)
<pre><code>public static String getStringGlobal(@StringRes int resId) { 
 if (res != null &amp;&amp; res.get() != null) { 
 return res.get().getString(resId); 
 } else {
 // This should not happen, you should throw an exception here, or you can return a fallback string to ensure the app still runs
 }
}
</code></pre>
As seen, you can also add error handling in case the instance of <code>Resources</code> is not available(this should not happen, but just in case).
You can then retrieve the string resource by calling
<pre class="lang-java prettyprint-override"><code>App.getStringGlobal(R.string./*your string resource name*/)
</code></pre>
So your <code>App.java</code>:
<pre class="lang-java prettyprint-override"><code>public class App extends Application { 
 private static WeakReference&lt;Resources&gt; res;

 @Override 
 public void onCreate() { 
 super.onCreate(); 
 res = new WeakReference&lt;&gt;(getResources()); 
 }

 public static String getStringGlobal(@StringRes int resId) { 
 if (res != null &amp;&amp; res.get() != null) { 
 return res.get().getString(resId); 
 } else {
 // This should not happen(reference to Resources invalid), you should throw an exception here, or you can return a fallback string to ensure the app still runs
 }
 }
}
</code></pre>

I want to read strings from an <code>xml</code> file before I do much of anything else like <code>setText</code> on widgets, so how can I do that without an activity object to call <code>getResources()</code> on?

How can I get a resource content from a static context?

在对小部件执行其他操作(如setText )之前，我希望从xml文件中读取字符串，那么如果没有activity对象来调用getResources()，我如何做到这一点呢？
