Answer 1

Sie MyMeasuredViewPager verwenden können, und verwenden Sie diese in einem Ort Ihrer Ansicht Pager

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

    public MyMeasuredViewPager(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); 
    } 
}
