Following is my integers.xml file,
<?xml version="1.0" encoding="utf-8"?>
<resources>
<integer name="LOCATION_ALARM_INTERVAL">60000</integer>
<integer name="MID_NIGHT_ALARM_INTERVAL">86400000</integer>
</resources>
if it was strings.xml, i could have access variable like below,
getString( R.string.<variable_name> );
but how can I do same to get value from integeres.xml file ?
when I write getResources().getInteger(R.integer. it is showing me 3 variable which I haven't declared.
So How can I access the variable which I declared in integers.xml file ?
It should be done like this:
Resources res = getResources();
int i= res.getInteger(R.integer.int_value);
where int_value is the variable name given in your xml
You're looking at the android.R.integer instead of your.namespace.R.integer.
Eclipse probably imported the wrong one; it does that sometimes, it's rather annoying.
Go to your imports at the top of the file and remove:
import android.R;
Then you should be able to use the quick-fix to add the correct import.
May be you have to clean your project once before accessing these file. I do it like this and it always works.
Resources r = getResources();
int i = r.getInteger(R.integer.<variable_name>)
Try to clean your project and restart your eclipse because this is the right way of doing it.
simple code :
int maximum = getContext().getResources().getInteger(R.integer.maximum);

In android can we do some thing like R.string.navigation_item_1 = _userName.getText().toString() where _userName is a TextView and navigation_item_1 is a string name in strings.xml. If not then what is the right procedure to pass a string from MainActivity to strings.xml
You can not customize the resources (no matter if string, drawable or what) in android at run time. The res folder could not be modified programmatically at all. For example you could not change a drawable at run time.
More answers to a similar question here: Change value of R.string programically
If you need a string value to be saved in your app, you could use SharedPrefferences for example
The answer is simple: you can't.
All xml resources files can't be modified during runtime. You can still assign that _userName.getText().toString() to a public instance variable but you can't add it to some resources which reference is created during build process.
It's right there in values/strings.xml in Android's source - why isn't it in android.R?
edit: I am referring to Android's built in string resources (android.R.string.…) and not my own project's resources - so, for example, while I can use android.R.string.cancel, I can't use android.R.string.share despite the fact that the two of them are declared in the same file in Android's source code
They are just resources under the resource folder.
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="share">hello</string>
</resources>
The above resource has a entry in R.java file which in under your package name. You can open R.java and have a look at it.
public static final int share=0x7f040000;
You can refer to the string in Strings.xml as
R.String.share
The R.strin.share is an int.
You can also get the string as
String s= getResources().getString(R.string.share);
Edit:
http://developer.android.com/guide/topics/resources/accessing-resources.html#PlatformResources.
Check the topic in the above link under the heading Accessing Platform Resources
Android contains a number of standard resources, such as styles, themes, and layouts. To access these resource, qualify your resource reference with the android package name.
For list of all resources check the link
http://developer.android.com/reference/android/R.html
The list from http://developer.android.com/reference/android/R.string.html
You are compiling for which SDK version??
Please check strings.xml of same SDK version..I think there is some mismatch in target SDK version and strings.xml(you are referring to, where "share" is present)
However i will recommend to add your own "share" string in application strings.xml, to avoid unwanted issues due to Android Fragmented nature.
android.R is the system's R
Your R is just R within your own package name. So just call it R.string.share instead of android.R.string.share when referring to it.
It's because it is not defined in android.R.string, but in com.android.internal.R$string. you cannot access it without some 'hack'.
public static int getReflactField(String className,String fieldName){
int result = 0;
try {
Class<?> clz = Class.forName(className);
Field field = clz.getField(fieldName);
field.setAccessible(true);
result = field.getInt(null);
} catch (Exception e) {
e.printStackTrace();
}
return result;
}
...
int share_id=getReflactField("com.android.internal.R$string", "share");
if(share_id!=0)
Toast.makeText(getContext(), ""+getResources().getString(share_id),0).show();
this works both on my android 4.4 and 8.0 device
Or simply use
getResources().getString(Resources.getSystem().getIdentifier("share","string", "android"))
I'm currently working on internationalization to my android application. This is the way I try to get the strings from the string.xml
tv.setText(context.getResources().getString(R.string.));
But Eclipse does not suggest any of my pre defined strings, just the standard Android Strings. My Folder structure look like this:
res/values/strings.xml
and
res/values-NO/strings.xml
I can see that the strings in these to files has some memory addresses in the R.java file, like this one for instance:
public static final int enterPassword=0x7f06003c;
I tried to Clean the Project, but its strange that eclipse doesnt suggest anything, the string exist in the R.java
Where is the problem ?
You should import you R class.
import xxx.xxx.R;
not
import android.R;
your xml looks like this:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="yellow">Yellow</string>
</resources>
and in java code:
tv.setText(getResources().getString(R.string.yellow));
and import android.R eventhough error exists than try to run the program than it will go off
import R with your Package Path instead of android.
like import com.example.R
instead of import android.R;
try this
Resources resources = getResources();
String string = resources.getString(R.string.text);
TextView tv= (TextView)findViewById(R.id.text);
tv.settext(string);
Please verify the imported R file path
Link for more information
Use this:
String tab_label = getResources().getString(R.string.));
and ensure that you are not imported android.R
I am having a strange error that I can not resolve in class R.java in my android application
the error is in the following line
public static final class string {
public static final int =0x7f05002f;
because it has no variable after the int
can anyone help me please with this error ?
R.java is auto-generated, and is not meant to be edited manually.
If you face issues, delete R.java and rebuild your project and it will be generated again, according to your layout.
If problem persists, look into your xml files ( strings.xml, layout.xml, etc) for any errors.
check your strings.xml file.It seems like you have saved some value without assigning any name to that.
Look for an entry not having any name attribute. something like <string>8</string>, either remove that or assign a name attribute to that like <string name="anyname">8</string>
A bad R.java would mean an error somewhere else. If deleting it and rebuilding the projetc doesn't solve it look at your manifest and other xml resources for errors.
Hi i am working with Gestures and i need to import but i m getting error
com.android.internal.R;
The import com.android.internal.R cannot be resolved
kindly help me , please
You don't say why you need access to com.android.internal.R, but the sad fact is that you simply cannot import it (the "internal" is a clue that it's not part of the public API). Google doesn't expose this because it is subject to change.
It is possible to get to the internal resources by calling Resources.getSystem(). To get the value of a particular resource identifier, you have to know its name and then use code like the following to find the value:
Resources res = Resources.getSystem();
int id = res.getIdentifier("resource name", "resource type", "android");
Be aware that any name that you use could disappear in future versions of Android.
I have a couple suggestions:
1) Make sure you don't have any other errors other than the R-related errors. Right-click your project folder in Eclipse, Android Tools -> Fix Project Properties.
2) Check to make sure you have the correct R imported. Sometimes the default Android.R can be imported.
Yes you can use the internal R with some dirty trick (dirty trick = Java reflection).
Just an example:
Class clasz = Class.forName("com.android.internal.R$styleable")
Field field = clasz.getDeclaredField("TextAppearance");
field.setAccessible(true);
int[] textAppearanceStyleArr = (int[])field.get(null);
field = clasz.getDeclaredField("TextAppearance_textSize");
field.setAccessible(true);
int textSizeStyle = (Integer)field.get(null);
First of all, what is Gestures ?
Do you have a package named com.android.internal in your gen folder ? Doest it contain R.java ?
If not, try Project->Clean in Eclipse. If it still doesn't work, you may have an error in your XML layout files.
