kotlin textview font size

// Step 1: Import the necessary classes
import android.content.Context
import android.graphics.Typeface
import android.util.AttributeSet
import androidx.appcompat.widget.AppCompatTextView

// Step 2: Create a custom class that extends AppCompatTextView
class CustomFontTextView : AppCompatTextView {

    // Step 3: Define a constructor for the custom class
    constructor(context: Context, attrs: AttributeSet?, defStyle: Int) : super(context, attrs, defStyle)

    // Step 4: Override the constructor with two parameters
    constructor(context: Context, attrs: AttributeSet?) : super(context, attrs)

    // Step 5: Set the custom font in the constructor
    init {
        val typeface = Typeface.createFromAsset(context.assets, "your_custom_font.ttf")
        setTypeface(typeface)
    }
}

Replace "your_custom_font.ttf" with the actual file path or name of your custom font. This assumes that the font file is located in the "assets" folder of your Android project.
