What is the equivalent of "android:fontFamily="sans-serif-light" in Java code?

My question is quite simple:

In every of my textview, I am currently using the attribute

android:fontFamily="sans-serif-light"

to provide a gorgeous look on post HC devices.

Unfortunately, this doesn't work with every widget and for my Spinners, I need to overwrite the Adapter.

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    //You can use the new tf here.

    if(convertView == null || convertView.getTag() == null) {
        // new view - populate 
        convertView = inflater.inflate(android.R.layout.simple_spinner_dropdown_item, parent, false);
        convertView.setTag(new Object());
    }

    CheckedTextView spinner_text=(CheckedTextView) convertView.findViewById(android.R.id.text1);
    //Typeface should be set here...
    return spinner_text;
    }
}

So, is there a way to get exactly the same result by code?

PS: No, I don't want to put a typeface in asset folder, I just want to use system one.

Solution 1:

It should be possible with setTypeface() and Typeface.create():

convertView.setTypeface(Typeface.create("sans-serif-light", Typeface.NORMAL));

See Docs:

Create a typeface object given a family name, and option style information. If null is passed for the name, then the "default" font will be chosen. The resulting typeface object can be queried (getStyle()) to discover what its "real" style characteristics are.

Note that excessively using Typeface.create() is bad for your memory, as stated in this comment. The suggested Hashtable is a good solution, but you have to modify it a little since you don't create your typeface from an asset.

Solution 2:

Android 4.1 (API Level 16) and Support Library 26 and higher

If you are using res -> font folder, you can use like this

  val typeface = ResourcesCompat.getFont(Context, R.font.YOUR_FONT)
  TextView.setTypeface(typeface)

Solution 3:

In my opinion there is still a way to apply system fonts programatically on TextView without having any memory issue and that is using textview.setTextAppearance method :

<style name="styleA">
    <item name="android:fontFamily">sans-serif</item>
    <item name="android:textStyle">bold</item>
    <item name="android:textColor">?android:attr/textColorPrimary</item>
</style>
<style name="styleB">
    <item name="android:fontFamily">sans-serif-light</item>
    <item name="android:textStyle">normal</item>
    <item name="android:textColor">?android:attr/textColorTertiary</item>
</style>


if(condition){
    textView.setTextAppearance(context,R.style.styleA);
}else{
    textView.setTextAppearance(context,R.style.styleB);
}

Solution 4:

Dynamically you can set the fontfamily similar to android:fontFamily in xml by using this,

For Custom font:

 TextView tv = ((TextView) v.findViewById(R.id.select_item_title));
 Typeface face=Typeface.createFromAsset(getAssets(),"fonts/mycustomfont.ttf"); 
 tv.setTypeface(face);

For Default font:

 tv.setTypeface(Typeface.create("sans-serif-medium",Typeface.NORMAL));

These are the list of default font family used, use any of this by replacing the double quotation string "sans-serif-medium"

FONT FAMILY                    TTF FILE                    

1  casual                      ComingSoon.ttf              
2  cursive                     DancingScript-Regular.ttf   
3  monospace                   DroidSansMono.ttf           
4  sans-serif                  Roboto-Regular.ttf          
5  sans-serif-black            Roboto-Black.ttf            
6  sans-serif-condensed        RobotoCondensed-Regular.ttf 
7  sans-serif-condensed-light  RobotoCondensed-Light.ttf   
8  sans-serif-light            Roboto-Light.ttf            
9  sans-serif-medium           Roboto-Medium.ttf           
10  sans-serif-smallcaps       CarroisGothicSC-Regular.ttf 
11  sans-serif-thin            Roboto-Thin.ttf             
12  serif                      NotoSerif-Regular.ttf       
13  serif-monospace            CutiveMono.ttf              

"mycustomfont.ttf" is the ttf file. Path will be in src/assets/fonts/mycustomfont.ttf , you can refer more about default font in this Default font family

Solution 5:

Option 1 - API 26 and higher

// Jave
Typeface typeface = getResources().getFont(R.font.myfont);
textView.setTypeface(typeface);

// Kotlin
val typeface = resources.getFont(R.font.myfont)
textView.typeface = typeface

Option 2 - API 16 and higher

// Java
Typeface typeface = ResourcesCompat.getFont(context, R.font.myfont);

// Kotlin
val typeface = ResourcesCompat.getFont(context, R.font.myfont)
