Change the source via xml

Question

I have the sources of my app on :

main > Assets >fonts

Is there any way to pass directly into xml? (android:typeface="")

Or just via Java ?

Thiago,

Your question is quite interesting. The solution I have always used is the one that follows in my answer. Even today I did not find another and I would just like to do also by XML, it would be so much easier!!! If you discover some better way, tell us! :-)

You can define a Textview specialization and apply the font you need. The class below can do this for you, but it is important to say that make this class a little more flexible, to reuse it in other projects, working better the setFont method.

import android.content.Context;
import android.graphics.Typeface;
import android.util.AttributeSet;
import android.widget.TextView;

public class ThiagoLuizTextView extends TextView {
    public CustomTextView(Context context) {
        super(context);
        setFont();
    }
    public ThiagoLuizTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
        setFont();
    }
    public ThiagoLuizTextView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        setFont();
    }

    private void setFont() {
        Typeface font = Typeface.createFromAsset(getContext().getAssets(), "fonts/RobotNew.ttf");
        setTypeface(font, Typeface.NORMAL);
    }
}

To use in XML, here is an example: (Of course it will depend on where your class is located in the structure of your project, so with.projecto.ui it must be replaced for its package structure)

• I tried to use a library called Caligraphy but the performance was terrible in code Profiling. It uses reflection for some things and I didn’t like it. I did it again anyway. In cases of using your custom textview, remember to adopt the viewholder pattern correctly in lists to have no problems.

I hope I helped and a hug,
