I am new to android. And i am implementing an application which will be in two langauge english and urdu. Basically there will be some text in arabic and its meaning will be in english or urdu based on the user selected language.
I want to change the font of arabic text, If i apply font in whole application it will change the look of urdu and english also. So is this will be fine to just apply font to each textview that contains arabic fonts using TypeFace or there is some better way to achieve this?
And also i want to know how to remove custom fonts in order to get default font back again through code. Sorry if this question is childish i just want to know what are the possibilities to do this.
for example if you want your application to support both English and Arabic strings (in addition to the default strings), you can simply create two additional resource directories called
/res/values-en
(for the English strings.xml) and/res/values-ar
(for the Arabic strings.xml).Within the
strings.xml
files, the resource names are the same.For example, the
/res/values-en/strings.xml
file could look like this:Whereas, the /res/values-ar/strings.xml file would look like this:
also , the /res/values-ur_IN/strings.xml file would look like this for urdu:
ur_IN for india ur_PK for pakisthan
A default layout file in the /res/layout directory that displays the string refers to the string by the variable name @string/hello, without regard to which language or directory the string resource is in.
The Android operating system determines which version of the string (French, English, or default) to load at runtime.A layout with a TextView control to display the string might look like this:
The string is accessed programmatically in the normal way:
For change the language you need to like that change lang..
Also see this example for single screen
Custom fonts for TextView based on languages inside String
String paragraph = "hey what's up ضعيف"; int NO_FLAG = 0; Bidi bidi = new Bidi(paragraph, NO_FLAG); int runCount = bidi.getRunCount(); for (int i = 0; i < runCount; i++) { String ltrtl = bidi.getRunLevel(i) % 2 == 0 ? "ltr" : "rtl"; String subString = paragraph.substring(bidi.getRunStart(i), bidi.getRunLimit(i)); Log.d(">>bidi:" + i, subString+" is "+ltrtl); }
prints:
So now one can easily build
TypefaceSpan
orMetricAffectingSpan
based on language direction like this:
