Question

Answer 1

Finally found a better solution for WrapContentViewPager!

The other solution contain some bug that hard to be solved, but I think this solution can be simply applied in our code

I found it on this site https://github.com/akhahaha/burn-android/blob/master/app/src/main/java/com/ucla/burn/android/WrapContentViewPager.java

Here is the code

public class WrapContentViewPager extends ViewPager {
        public WrapContentViewPager(Context context) {
            super(context);
        }

        public WrapContentViewPager(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);
        }
    }
