here are some other post that i have visited but didn't help me to solve my problem
If need more information please do let me know. Thanks in advance. Your efforts will be appreciated.
There's a library called Calligraphy https://github.com/chrisjenx/Calligraphy
Or create a custom TextView and set font at constructor In this way you should replace all the TextView in your xmls to CustomFontTextView
import android.content.Context;
import android.graphics.Typeface;
import android.support.v7.widget.AppCompatTextView;
import android.util.AttributeSet;
public class CustomFontTextView extends AppCompatTextView {
public CustomFontTextView(Context context) {
super(context);
setCustomFont();
}
public CustomFontTextView(Context context, AttributeSet attrs) {
super(context, attrs);
setCustomFont();
}
public CustomFontTextView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
setCustomFont();
}
private void setCustomFont() {
setTypeface(Typeface.create("sans-serif-light", Typeface.NORMAL));
}
}
Typeface.create()
it's not safe approach to get a font.
