How to click views behind a Toolbar?

Take a look at the implementation of Toolbar. It eats touch events, regardless of the clickable attribute.

@Override
public boolean onTouchEvent(MotionEvent ev) {
    // Toolbars always eat touch events, but should still respect the touch event dispatch
    // contract. If the normal View implementation doesn't want the events, we'll just silently
    // eat the rest of the gesture without reporting the events to the default implementation
    // since that's what it expects.

    final int action = MotionEventCompat.getActionMasked(ev);
    if (action == MotionEvent.ACTION_DOWN) {
        mEatingTouch = false;
    }

    if (!mEatingTouch) {
        final boolean handled = super.onTouchEvent(ev);
        if (action == MotionEvent.ACTION_DOWN && !handled) {
            mEatingTouch = true;
        }
    }

    if (action == MotionEvent.ACTION_UP || action == MotionEvent.ACTION_CANCEL) {
        mEatingTouch = false;
    }

    return true;
}

The solution is to extend from Toolbar and override onTouchEvent.

public class NonClickableToolbar extends Toolbar {

    @Override
    public boolean onTouchEvent(MotionEvent ev) {
        return false;
    }
}

Toolbar consumes all clicks. You need to subclass Toolbar, like @Matthias Robbens already mentioned.

If you still want to be able to set a click listener on the toolbar, use this:

/** Do not eat touch events, like super does. Instead map an ACTION_DOWN to a click on this 
 * view. If no click listener is set (default), we do not consume the click */
@SuppressLint("ClickableViewAccessibility")
@Override
public boolean onTouchEvent(MotionEvent ev) {
    if (ev.getAction() == MotionEvent.ACTION_DOWN || ev.getAction() == MotionEvent.ACTION_POINTER_DOWN){
        return performClick();
    }

    return false;
}
