Android Text Size

Question

Hello i have a app which makes 3 wheels from 3 different arrays of words i am trying to make the text size of the words in the array smaller can someone point me in the right direction.

I have tried the textsize in my xml but it dosent seem to work so is there a way around this in the java?

Thanks.

    public class PasswActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.passw_layout);
    initWheel(R.id.passw_1, new String[] { "One", "Two", "Three" });
    initWheel(R.id.passw_2, new String[] { "Four", "Five", "Six" });
    initWheel(R.id.passw_3, new String[] { "Seven", "Eight", "Nine" });



    Button mix = (Button) findViewById(R.id.btn_mix);
    mix.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            mixWheel(R.id.passw_1);
            mixWheel(R.id.passw_2);
            mixWheel(R.id.passw_3);

        }
    });

}


private boolean wheelScrolled = false;


OnWheelScrollListener scrolledListener = new OnWheelScrollListener() {
    public void onScrollingStarted(WheelView wheel) {
        wheelScrolled = true;
    }

    public void onScrollingFinished(WheelView wheel) {
        wheelScrolled = false;

    }
};


private OnWheelChangedListener changedListener = new OnWheelChangedListener() {
    public void onChanged(WheelView wheel, int oldValue, int newValue) {
        if (!wheelScrolled) {

        }
    }
};


private void initWheel(int id, String[] values) {
    WheelView wheel = getWheel(id);
    wheel.setViewAdapter(new ArrayWheelAdapter<String>(this, values));
    wheel.setCurrentItem((int) (Math.random() * 10));
    wheel.addChangingListener(changedListener);
    wheel.addScrollingListener(scrolledListener);
    wheel.setCyclic(true);
    wheel.setInterpolator(new AnticipateOvershootInterpolator());

}


private WheelView getWheel(int id) {
    return (WheelView) findViewById(id);

}



private boolean testPin(int v1, int v2, int v3, int v4) {
    return testWheelValue(R.id.passw_1, v1)
            && testWheelValue(R.id.passw_2, v2)
            && testWheelValue(R.id.passw_3, v3);

}


private boolean testWheelValue(int id, int value) {
    return getWheel(id).getCurrentItem() == value;
}


private void mixWheel(int id) {
    WheelView wheel = getWheel(id);
    wheel.scroll(-25 + (int) (Math.random() * 50), 2000);
}
   }

Assume you are using KanKan Wheel. Actually the textSize is set through wheelAdapter, not wheelView. I know this is weird, but let's face the facts.

You need use kankan.wheel.widget.adapters.AbstractWheelTextAdapter, extend a subclass, and set textSize after you initialize your wheelAdapter and before set it to wheelView:

private class MyWheelAdapter extends AbstractWheelTextAdapter {
 ... ...
}

myWheelAdapter = new MyWheelAdapter(getApplicationContext());
myWheelAdapter.addAll(myWheelList);
myWheelAdapter.setTextSize(18);
// initialise wheel widget
myWheelView = (WheelView) findViewById(R.id.my_wheel_view);
myWheelView.setViewAdapter(myWheelAdapter);

Hope that help.
