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. Unf

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

valtypeface= 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 :

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

ForCustom font:

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

ForDefault 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

"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

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

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

Option 2 - API 16 and higher

// JavaTypefacetypeface= ResourcesCompat.getFont(context, R.font.myfont);

// Kotlinvaltypeface= ResourcesCompat.getFont(context, R.font.myfont)
