Set font at runtime, TextView

To set In-built Font at Run-Time:

• First of all, To Change Font-face, a Typeface class is used.

• Now, at Run-Time, to set the font-face, Use setTypeface(Typeface) from the Java code

• at Design-Time, to set the font-face, Use android:typeface="serif"

For example:

<TextView android:text="@+id/TextView01"
 android:id="@+id/TextView01"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:textSize="30px"
 android:textStyle="italic"
 android:typeface="serif" />

To set Custom font(s) in your Android application

To do this, simply create an assets/ folder in the project root, and put your fonts (in TrueType, or TTF, form) in the assets. You might, for example, create assets/fonts/ and put your TTF files in there:

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

You can have .ttf font in your asset folder. Say font's name is "default.ttf" and you just now have to write below 2 lines of code

TextView text = new TextView(this);
text.setTypeface(Typeface.createFromAsset(getAssets(), "default.ttf"));

You must also we careful because different font have different sizes. You may need to set size as :

text.setTextSize(20);
