Apply Custom Fonts in Xml without any change in Java File.

Hello all,

Today I going to share the code to apply the custom fonts in resource file without any change in source file .

For this you first need to download the fonts which you want to apply on the Textview.

I have download the fonts from the site : 1001fonts

Then paste it in the assets folder of your project.

Now let's move to the coding section:

First make a attribute xml file in values folder, named : attrs.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
     <declare-styleable name="TextViewPlus">
        <attr name="customFont" format="string"/>
    </declare-styleable>
    

</resources>

Now make a package for adding custom font helper classes,

First make a java class in this package,I have named it: FontHelper.java ,then copy the following code:

import java.util.HashMap;
import java.util.Map;
import com.blogdemo.R;
import android.content.Context;
import android.content.res.TypedArray;
import android.graphics.Typeface;
import android.util.AttributeSet;
import android.util.Log;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;

public class FontHelper {
 
private static final String TAG = "TextView";
private static Map<String ,Typeface> fonts = new HashMap<String ,Typeface>();
 public static Typeface getTypeFace(Context context, String fontPath) {
  
 if (!fonts.containsKey(fontPath)) {
   
  Typeface font = Typeface.createFromAsset(context.getAssets(), fontPath);
  fonts.put(fontPath, font);
 }
  
 return fonts.get(fontPath);
}
 
public static void setFont(View view, Typeface font) {
 
       if (view instanceof ViewGroup) 
 {
           for (int i = 0; i < ((ViewGroup)view).getChildCount(); i++) {
   
               setFont(((ViewGroup)view).getChildAt(i), font);
           }
       } else if (view instanceof TextView) {
  
           ((TextView) view).setTypeface(font);
       }
   }
 
public static void setFont(Context ctx, TextView view, AttributeSet attrs) {
 
                        TypedArray a = ctx.obtainStyledAttributes(attrs, R.styleable.TextViewPlus);
       String customFont = a.getString(R.styleable.TextViewPlus_customFont);
       setFont(ctx, view,customFont);
       a.recycle();
       

}
 public static boolean setFont(Context ctx, TextView view, String fontPath) {
 
 boolean successful = true; 
 try {
   Typeface tf = FontHelper.getTypeFace(ctx, fontPath);
  view.setTypeface(tf);
 } catch (Exception e) {
   
  Log.e(TAG, "Error to get typeface: " + e.getMessage());
  successful = false;
 }
 
 return successful;
 }
}

Now  again make another class in the same package I have named it : TextViewPlus.java


import java.util.HashMap;
import com.blogdemo.R;
import android.content.Context;
import android.content.res.TypedArray;
import android.graphics.Typeface;
import android.util.AttributeSet;
import android.util.Log;
import android.widget.TextView;

public class TextViewPlus extends TextView {
    private static final String TAG = "TextView";
    
private HashMap<String,Typeface> fontMap = new HashMap<String, Typeface>();
    public  TextViewPlus(Context context) {
        super(context);
    }

    public TextViewPlus(Context context, AttributeSet attrs) {
        super(context, attrs);
        FontHelper.setFont(context, this, attrs);
    }

    public TextViewPlus(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        FontHelper.setFont(context, this, attrs);
    }

    private void setCustomFont(Context ctx, AttributeSet attrs) {
        TypedArray a = ctx.obtainStyledAttributes(attrs, R.styleable.TextViewPlus);
        String customFont = a.getString(R.styleable.TextViewPlus_customFont);
      FontHelper.setFont(ctx, this, attrs);
        a.recycle();
    }

    public boolean setCustomFont(Context ctx, String asset) {
        Typeface tf = null;
        try {
        tf = Typeface.createFromAsset(ctx.getAssets(), asset); 
        fontMap.put(asset,tf);
        } catch (Exception e) {
            Log.e(TAG, "Could not get typeface: "+e.getMessage());
            return false;
        }

        setTypeface(tf);  
        return true;
    }


}

That's all now let's move to the resource folder,make a xml which will contain the textviews with different fonts,I have named it : main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
     xmlns:foo="http://schemas.android.com/apk/res/com.blogdemo"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" 
    android:background="#FFFFFF">
    
      <com.customtext.TextViewPlus
       android:id="@+id/txt_1_mainlayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        
        android:layout_marginLeft="26dp"
        
        android:layout_marginRight="26dp"
        android:layout_marginTop="20dp"
        android:text="@string/sample_text"
        android:textSize="20dp"
        android:textColor="#000000"
        foo:customFont="Liima.ttf"
      
           >
    </com.customtext.TextViewPlus> 
    
       <com.customtext.TextViewPlus
       android:id="@+id/txt_2_mainlayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginLeft="26dp"
        android:layout_marginRight="26dp"
        android:layout_marginTop="40dp"
        android:text="@string/sample_text"
        android:textSize="20dp"
        android:textColor="#FF0000"
        
        foo:customFont="Tusj.ttf"
      
           >
    </com.customtext.TextViewPlus> 
   </LinearLayout>


->That's all, now use this xml and textview ,same as normal textviews. here one thing should be noticed in this xml :

   xmlns:foo="http://schemas.android.com/apk/res/com.blogdemo"

you can replace com.blogdemo with your main package.

Here is the screen shot for the custom text fonts:
