Using a custom typeface in Android

Question

I want to use a custom font for my android application which I am creating.
I can individually change the typeface of each object from Code, but I have hundreds of them.

So,

• Is there a way to do this from the XML? [Setting a custom typeface]
• Is there a way to do it from code in one place, to say that the whole application and all the components should use the custom typeface instead of the default one?

Answer 1

Yes It is possible.

You have to create a custom view which extends text view.

In attrs.xml in values folder:

<resources>
    <declare-styleable name="MyTextView">
        <attr name="first_name" format="string"/>
        <attr name="last_name" format="string"/>
        <attr name="ttf_name" format="string"/>
    </declare-styleable>
</resources>

In main.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
     xmlns:lht="http://schemas.android.com/apk/res/com.lht"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
    <TextView  android:layout_width="fill_parent" 
        android:layout_height="wrap_content"
        android:text="Hello"/>
    <com.lht.ui.MyTextView  
        android:id="@+id/MyTextView"
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content"
        android:text="Hello friends"
        lht:ttf_name="ITCBLKAD.TTF"
        />   
</LinearLayout>

In MyTextView.java:

package com.lht.ui;

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

public class MyTextView extends TextView {

    Context context;
    String ttfName;

    String TAG = getClass().getName();

    public MyTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
        this.context = context;

        for (int i = 0; i < attrs.getAttributeCount(); i++) {
            Log.i(TAG, attrs.getAttributeName(i));
            /*
             * Read value of custom attributes
             */

            this.ttfName = attrs.getAttributeValue(
                    "http://schemas.android.com/apk/res/com.lht", "ttf_name");
            Log.i(TAG, "firstText " + firstText);
            // Log.i(TAG, "lastText "+ lastText);

            init();
        }

    }

    private void init() {
        Typeface font = Typeface.createFromAsset(context.getAssets(), ttfName);
        setTypeface(font);
    }

    @Override
    public void setTypeface(Typeface tf) {

        // TODO Auto-generated method stub
        super.setTypeface(tf);
    }

}
