There is no way to setup button drawable of RadioButton widget in layout XML file, so we should do it at Activity create event:

    private void setupUI() {
        RadioButton rbFirst = (RadioButton) findViewById(R.id.first);
        RadioButton rbSecond = (RadioButton) findViewById(R.id.second);
        RadioButton rbThird = (RadioButton) findViewById(R.id.third);
        RadioButton rbFourth = (RadioButton) findViewById(R.id.fourth);
        rbFirst.setButtonDrawable(R.drawable.ebay);
        rbSecond.setButtonDrawable(R.drawable.flickr);
        rbThird.setButtonDrawable(R.drawable.skype);
        rbFourth.setButtonDrawable(R.drawable.you_tube);
        RadioGroup rg = (RadioGroup) findViewById(R.id.states);
        rg.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
            public void onCheckedChanged(RadioGroup group, final int checkedId) {
                switch (checkedId) {
                case R.id.first:
                    getTabHost().setCurrentTab(0);
                    break;
                case R.id.second:
                    getTabHost().setCurrentTab(1);
                    break;
                case R.id.third:
                    getTabHost().setCurrentTab(2);
                    break;
                case R.id.fourth:
                    getTabHost().setCurrentTab(3);
                    break;
                }
            }
        });
    }

Final result:

And as usual there are source code and executable file.

CREATE VIRTUAL TABLE TableName
    USING FTS3(ColOne TEXT, ColTwo DATETIME)

Your table must contains at least 1 TEXT field.
The FTS3 virtual table acts like a regular table, but you need to manually maintain the indexes to keep referential integrity — you should UPDATE the FTS3 table from time to time.
The full-text query in SQLite looks like this:

SELECT * FROM TableName WHERE ColOne MATCH 'search phrase'

Make sure you use MATCH instead of equals or LIKE to scan a TEXT column in a virtual table.
There is a sample application to demonstrate full-text search in action:
