Multi-State Toggle Button

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);
    }
});

You can create a custom ImageButton to achieve this, you need 3 different images in this case. You can also add more states if you want.

public class FlashButton extends ImageButton {

    public enum FlashEnum {
        AUTOMATIC, ON, OFF
    }

    public interface FlashListener {
        void onAutomatic();
        void onOn();
        void onOff();
    }

    private FlashEnum mState;
    private FlashListener mFlashListener;

    public FlashButton(Context context, AttributeSet attrs) {
        super(context, attrs);

        //Sets initial state
        setState(FlashEnum.AUTOMATIC);
    }


    @Override
    public boolean performClick() {
        super.performClick();
        int next = ((mState.ordinal() + 1) % FlashEnum.values().length);
        setState(FlashEnum.values()[next]);
        performFlashClick();
        return true;
    }


    private void performFlashClick() {
        if(mFlashListener == null)return;
        switch (mState) {
            case AUTOMATIC:
                mFlashListener.onAutomatic();
                break;
            case ON:
                mFlashListener.onOn();
                break;
            case OFF:
                mFlashListener.onOff();
                break;
        }
    }

    private void createDrawableState() {
        switch (mState) {
            case AUTOMATIC:
                setImageResource(R.drawable.ic_flash_auto);
                break;
            case ON:
                setImageResource(R.drawable.ic_flash_on);
                break;
            case OFF:
                setImageResource(R.drawable.ic_flash_off);
                break;
        }
    }


    public FlashEnum getState() {
        return mState;
    }

    public void setState(FlashEnum state) {
        if(state == null)return;
        this.mState = state;
        createDrawableState();

    }

    public FlashListener getFlashListener() {
        return mFlashListener;
    }

    public void setFlashListener(FlashListener flashListener) {
        this.mFlashListener = flashListener;
    }

}
