[nambv]

@patelhari yes, I face this issue too

[ghost]

Same error here

[kamleshkarwande]

I am also facing the same error. Happenend after updateing the project to latest version. API 26

[ratriretno]

any solution ?

[mohitissar]

same issue here

[patelhari]

@nambv , @RonEskinder , @kamleshkarwande , @ratriretno , @mohitissar
For me only the solution is below

change getTargetFragment() to getParentFragment() in DateFragment.java and TimeFragment.java

@Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);

        try
        {
            mCallback = (DateChangedListener) getParentFragment();
        }
        catch (ClassCastException e)
        {
            throw new ClassCastException("Calling fragment must implement " +
                "DateFragment.DateChangedListener interface");
        }
    }

change in onMeasure fix height value in CustomViewPager.java

@Override
    public void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
    {
        mDatePicker = (DatePicker) findViewById(R.id.datePicker);
        mTimePicker = (TimePicker) findViewById(R.id.timePicker);

        int height = 600;

        for (int i = 0; i < getChildCount(); i++)
        {
            View child = getChildAt(i);
            child.measure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(0, MeasureSpec.AT_MOST));
            int h = child.getMeasuredHeight();
            if (h > height)
                height = h;
        }

        heightMeasureSpec = MeasureSpec.makeMeasureSpec(height, MeasureSpec.AT_MOST);

        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
        //setMeasuredDimension(318, 318);
    }
