一、listview

public class ListViewForScrollView extends ListView {

public ListViewForScrollView(Context context) {
super(context);
}

public ListViewForScrollView(Context context, AttributeSet attrs) {
super(context, attrs);
}

public ListViewForScrollView(Context context, AttributeSet attrs,
int defStyle) {
super(context, attrs, defStyle);
}

@Override
/**
* 重写该方法，达到使ListView适应ScrollView的效果
*/
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
  int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,
    MeasureSpec.AT_MOST);
  super.onMeasure(widthMeasureSpec, expandSpec);
}
}

二、gridview

public class GridViewForScrollView extends GridView {

public GridViewForScrollView(Context context) {
super(context);
}

public GridViewForScrollView(Context context, AttributeSet attrs) {
super(context, attrs);
}

public GridViewForScrollView(Context context, AttributeSet attrs,
   int defStyle) {
  super(context, attrs, defStyle);
}

@Override
/**
* 重写该方法，达到使GridView适应ScrollView的效果
*/
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
  int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,
    MeasureSpec.AT_MOST);
  super.onMeasure(widthMeasureSpec, expandSpec);
}
}
