Answer 1

I believe it's trying to tell you to add a no argument constructor.

public CollapsingTitleLayout(){}

The object has other constructors but it doesn't have the no-value constructor above.

    public CollapsingTitleLayout(Context context) {
    this(context, null);
}

public CollapsingTitleLayout(Context context, AttributeSet attrs) {
    this(context, attrs, 0);
}

public CollapsingTitleLayout(Context context, AttributeSet attrs, int defStyleAttr) {
    super(context, attrs, defStyleAttr);

Answer 2

It seems that your parent class has no default constructor so you can't have an implicit one.

You have to create at least one constructor that calls one of the 'super(...)' possibilities.
