Android: Integer from Xml Resource

Android: integer from xml resource

Yes it is possible, it would look like this:

1. Create an xml resources file in the folder /res/values/ called integers.xml.

   You are free to give it any name as you want, but choose one that is obvious.

2. In that resources file, create your integer values.

   Your file then looks something like that:

   <?xml version="1.0" encoding="utf-8"?>
   <resources>    
       <integer name="maximum">100</integer>
       ...
   
   </resources>
   

3. Reference the integer value in the Java code like this:

   It's a bit different from the getString(), you have to take a little detour.

   ProgressDialog progressBar = new ProgressDialog(getContext());
   int max = getContext().getResources().getInteger(R.integer.maximum);
   progressBar.setMax(max);
   

How to get Integer value from res/integers.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.

Change int from xml Resource

First thing's first Resources CAN NOT be Changed or Modified once an apk has been built. You can only add values to resources that need not to be modified.

So what to do? Preferences allow you to save and modify values at run time. This SO explains how to use Shared Preferences in your app.

Have a look at this for easy to use Utility for Shared Preferences.

Accessing integer resources in xml

Finally I am able to access integer resource in java code and integer value as dimen in xml.

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <dimen name="input_field_padding">20dip</dimen>
    <integer name="input_field_padding">20</integer>
</resources>

In xml file:-

<EditText
    android:id="@+id/user_name"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"    
    android:padding="@dimen/input_field_padding" /> 

In java file:-

EditText mUsername = (EditText) this.findViewById(R.id.user_name);
//int padding = this.getResources().getInteger(R.integer.input_field_padding);
int padding = (int) this.getResources().getDimension(R.dimen.input_field_padding);
mUsername.setPadding(padding, padding, padding, padding);

how to get integer value from strings.xml in android

First, don't put them in strings.xml. Put them in integers.xml.

Second, you should use context.getResources().getInteger(R.integer.GUI_OK), where context is an instance of a Context object, such as an Activity or Service.

R.integer.GUI_OK is simply a resource value which Android uses to retrieve the actual value of that resource.

Get integer value from dimens.xml resource file in Android

Why not store the integer in res/integers.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <integer name="quantity_length">12</integer>
</resources>

And to access the values in code

int myInteger = getResources().getInteger(R.integer.quantity_length);

Or in XML

android:maxLength="@integer/quantity_length"

How to use integer resources within string resources in android

short version is that you can't mix resources like this, but you can use in Java:

getResources.getString(R.string.some_string,
                       getResources.getInteger(R.integer.some_integer)
                      );

and then in your String XML

<string name="some_string">This is my string num %d in a row</string>

that way the %d get replaced by the integer you pass in the getString

Getting different integer value from resource folder in Android

The device density is 165dpi thats make it mdpi device. The resolution is 320px x 480px and because its mdpi thats mean. The device is 320dp x 480dp.

And from Google doc you can see this device is Normal.

xlarge screens are at least 960dp x 720dp

large screens are at least 640dp x 480dp

normal screens are at least 470dp x 320dp

small screens are at least 426dp x 320dp

For me I would prefer to use sw-xxx for example (you need to check the values):

res/values => 3  
res/values-sw330 => 4
