public class CustomViewPager extends ViewPager {
 
    public CustomViewPager(Context context) {
        super(context);
    }
 
    public CustomViewPager(Context context, AttributeSet attrs) {
        super(context, attrs);
    }
 
    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
 
        int height = 0;
        for (int i = 0; i < getChildCount(); i++) {
            View child = getChildAt(i);
            child.measure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
            int h = child.getMeasuredHeight();
            if (h > height)
                height = h;
        }
 
        heightMeasureSpec = MeasureSpec.makeMeasureSpec(height, MeasureSpec.EXACTLY);
 
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
    }
}
