If you have a .ttf font file with your symbols, place it in the /assets folder then use it on a TextView like this:

Typeface font = Typeface.createFromAsset(getAssets(), "font.ttf");
TextView tv = (TextView) findViewById(R.id...);
tv.setTypeface(font);

As for using the keyboard see: http://www.addictivetips.com/mobile/create-your-own-custom-keyboard-for-android-devices/ and creating custom android keyboard layout
