Using Custom Fonts

From ModMyGPhone Wiki

Android comes with 3 fonts (Sans, Serif, Monospace) which can be accesed using android:typeface="FONT_NAME". But most of the times you would want to use your own fonts instead of the stock ones. Android provides an "assets" folder where you can put your TTF font files and access them from within the code.

There are two ways of doing this,

1. Assign the Typeface object to TextView,

2. Paint the Typeface on screen Canvas.

Method 1 - Assigning Typeface object to TextView

public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        TextView bauhs = null,chiller=null,broadw=null,joker=null ;
        Button mag=null;
        
        setFont(bauhs, "fonts/BAUHS93.TTF", R.id.bauhs);
        
        setFont(broadw, "fonts/BROADW.TTF", R.id.broadw);
        
        setFont(chiller, "fonts/CHILLER.TTF", R.id.chiller);
        
        setFont(joker, "fonts/JOKERMAN.TTF", R.id.joker);
        
        setFont(mag, "fonts/MAGNETOB.TTF", R.id.magneto);
        
             
    }
    
    void setFont(TextView name, String path, int res)
    {
    	name=(TextView)findViewById(res);  
        Typeface font = Typeface.createFromAsset(this.getAssets(), path); 
        
        name.setTypeface(font); 
    	
    }

- "Typeface" is the class for handling fonts.

- The createFromAsset() method is used to specify the font path.

- font object is assigned to the TextView name

Method 2 - Drawing the font on screen canvas

@Override
    protected void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(new FontView(this));
    }
    
    private static class FontView extends View 
    {
        private Paint mPaint = new Paint(Paint.ANTI_ALIAS_FLAG);
        private Typeface mFace;
        
        public FontView(Context context) 
        {
            super(context);

           // mFace = Typeface.createFromAsset(getContext().getAssets(),"fonts/MAGNETOB.TTF");
            
            mPaint.setTextSize(34);
            mPaint.setColor(Color.WHITE);
        }
        
        @Override 
        protected void onDraw(Canvas canvas) 
        {
            canvas.drawColor(Color.BLACK);
            
            drawFont(canvas, "fonts/BAUHS93.TTF", 50, "Bauhaus 93");
            
            drawFont(canvas, "fonts/BROADW.TTF", 150, "Broadway");
            
            drawFont(canvas, "fonts/CHILLER.TTF", 250, "Chiller");
            
            drawFont(canvas, "fonts/JOKERMAN.TTF", 350, "Jokerman");
           
        }
        
        void drawFont(Canvas canvas, String path, int y, String name)
        {
        	 mFace = Typeface.createFromAsset(getContext().getAssets(),path);
        	
        	 mPaint.setTypeface(mFace);
             canvas.drawText(name, 30, y, mPaint);
             
        	
        	
        }
    }

- We need to extend the View class to access and override the onDraw() method.

- A Paint object is created which allows us to set the font size and color.

- The TypeFace object mFace is assigned to mPaint which is drawn on screen using the drawText().

- drawText() takes 3 parameters, the text to be painted, its X-Y location and the Paint object.

  
Note: There is a difference between arial.ttf and ARIAL.TTF . If it ARIAL.TTF in your /assets folder and arial.ttf in your code, it will not work. 

So if you have set the path correct but still wondering why the font is not being displayed, check this naming.
