如何在不折叠的情况下将ListView放入ScrollView？

 ```java

 public class NonScrollableListView extends ListView {

     public NonScrollableListView(Context context) {

         super(context);

     }

     public NonScrollableListView(Context context, AttributeSet attrs) {

         super(context, attrs);

     }

     public NonScrollableListView(Context context, AttributeSet attrs, int defStyleAttr) {

         super(context, attrs, defStyleAttr);

     }

     @Override

     protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {

         int heightMeasureSpecCustom = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);

         super.onMeasure(widthMeasureSpec, heightMeasureSpecCustom);

         ViewGroup.LayoutParams params = getLayoutParams();

         params.height = getMeasuredHeight();

     }

 }

 ```
