Answer 1

Zuerst müssen Sie Ihre Viewpager außer Kraft zu setzen und fügen

@Override 
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { 
     super.onMeasure(widthMeasureSpec, 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); 
    } 

Auch für RecyclerView hinzufügen recyclerView.setHasFixedSize(true);
