Is it possible to use android:inputType with a string resource

I'm making an android app for multiple languages. I would like to set the inputType for an EditText view to be different based on the keyboard language. In the XML file I've tried:

android:inputType="@string/xyz"

and in the Strings resource file string xyz would be

<string name="xyz">number</string>

I was hoping that this was a smart idea for easily changing the input type bases on language. For example, if the language were English I would set xyz to letters, but in Japanese I would have xyz as numbers. I was trying to avoid doing this programmatically because as soon as I start entering input filters in code much of my XML settings are ignored, even if they are not directly overridden by the new code.

I get an error though when I try to call this string resource to the inputType. Any assistance would be greatly appreciated.

Also, you can use (and override) style for your EditText (with attrs) for each language qualificator

f.e.

 <style name="PinCodeInputType">
    <item name="android:inputType">numberDecimal</item>
</style>



<EditText
    android:id="@+id/code"
    style="@style/PinCodeInputType"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    />

You can do it only via XML but you have to use an integer and not a string resource:

In your value folder

<integer name="myInputType">12</integer> <!-- numberPassword -->

In your layout

android:inputType="@integer/myInputType"

The integer values are listed here: https://developer.android.com/reference/android/widget/TextView.html#attr_android:inputType

Yes you can achieve this programmatically since inputType can take an integer value. Here is the implementation it is actually so easy.

TYPE_CLASS_TEXT has a constant value: 1

TYPE_CLASS_NUMBER has constant value: 2

This is the value your strings.xml (which you are going to localise): For example:

input_type value in strings for English (text):

<string name="input_type">1</string>

input_type value in strings for Japanese (number):

<string name="input_type">2</string>

In your Activity, declare your EditText and set the inputType from strings.xml so it will be set according to the localisation:

editText = (EditText)findViewById(R.id.editText1);
editText.setInputType(Integer.parseInt(getResources().
                                       getString(R.string.input_type)));

No, you cannot do this. The android:inputType attribute is defined as using flags that are also defined by Android. You cannot provide an arbitrary string value for this attribute, you can only use those pre-defined flags.
