[SOLVED]How customize/extend/ Spinner

You will need to take control over what goes into the ListView and
Spinner. I have not experimented with these techniques on Spinner, but
on ListView, you will need to override getView() (on ArrayAdapter) or
newView() and bindView() (on CursorAdapter).
Here is a free excerpt from one of my books that demonstrates the technique:

http://commonsware.com/Android/excerpt.pdf

In your case, you would use your Typeface object to update the font used
by the TextView widgets in your rows.

In principle, you could do this via a wrapping adapter -- this would be
more reusable but a bit slower. I have an AdapterWrapper base class here:

http://github.com/commonsguy/cwac-adapter

and some projects that use it here:

http://github.com/commonsguy/cwac-endless
http://github.com/commonsguy/cwac-thumbnail

You also need to override getDropDownView().

[SOLVED] Android: Convert dip to px.

It uses pixels, but I'm sure you're wondering how to use dips instead. The answer is inTypedValue.applyDimension(). Here's an example of how to convert dips to px in code:

// Converts 14 dip into its equivalent px
Resources r = getResources();
float px = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 14, r.getDisplayMetrics());

[SOLVED] Android: Using Custom Fonts

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.
