The solution to the GridView nested in ScrollView in Android is only one line

public void setListViewHeightBasedOnChildren(ListView listView) { 
ListAdapter listAdapter = (); 
if (listAdapter == null) { 
return; 
} 
int totalHeight = 0; 
for (int i = 0; i < (); i++) { 
View listItem = (i, null, listView); 
(0, 0); 
totalHeight += (); 
} 
 params = (); 
 = totalHeight + (() * (() - 1)); 
((MarginLayoutParams)params).setMargins(15, 15, 15, 15); 
(params);
}

public class MyListView extends ListView { 
public MyListView(Context context) { 
// TODO Auto-generated method stub 
super(context); 
} 
public MyListView(Context context, AttributeSet attrs) { 
// TODO Auto-generated method stub 
super(context, attrs); 
} 
public MyListView(Context context, AttributeSet attrs, int defStyle) { 
// TODO Auto-generated method stub 
super(context, attrs, defStyle); 
} 
@Override 
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { 
// TODO Auto-generated method stub 
int expandSpec = (Integer.MAX_VALUE >> 2, 
MeasureSpec.AT_MOST); 
(widthMeasureSpec, expandSpec); 
} 
}

public class MyGridView extends GridView{ 
public MyGridView(Context context, AttributeSet attrs) { 
super(context, attrs); 
} 
public MyGridView(Context context) { 
super(context); 
} 
public MyGridView(Context context, AttributeSet attrs, int defStyle) { 
super(context, attrs, defStyle); 
} 
@Override 
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { 
int expandSpec = (Integer.MAX_VALUE >> 2, 
MeasureSpec.AT_MOST); 
(widthMeasureSpec, expandSpec); 
} 
}
