Multi-State Toggle Button

Question

In the app I've been working on, I would like to have a multiple-state (in my case, three) toggle button, instead of the two that ToggleButton provides. I've tried to start my own that extends Button, following the CompoundButton source, but quite honestly reading over its source got a bit overwhelming.

Is there a way to do a three-state toggle button using just a selector xml or something, or perhaps another method I haven't thought of? I'm rather at a loss of how to do this.

Answer 1

I implemented a multi-state toggle button, the source code is here

This is how it looks:

And it's quite easy to use it:

<org.honorato.multistatetogglebutton.MultiStateToggleButton
    android:id="@+id/mstb_multi_id"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginTop="10dip"
    mstb:values="@array/planets_array" />

In your activity:

MultiStateToggleButton button2 = (MultiStateToggleButton) this.findViewById(R.id.mstb_multi_id);
button2.setOnValueChangedListener(new ToggleButton.OnValueChangedListener() {
    @Override
    public void onValueChanged(int value) {
        Log.d(TAG, "Value: " + value);
    }
});
