ScrollView嵌套GridView和ListView行高问题

1.GidView使用的时候可以先重载GirdView例如:

public class MyGridView extends GridView {

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

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

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

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {

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

        super.onMeasure(widthMeasureSpec, expandSpec);
    }

}

在布局文件中使用

            <com.vaqp.utils.MyGridView
                android:id="@+id/location_gview"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:background="#D3D3D3"
                android:columnWidth="100dp"
                android:numColumns="auto_fit"
                android:paddingLeft="10dip"
                android:verticalSpacing="1dip" >
            </com.vaqp.utils.MyGridView>

2.ListView在setAdapter后调用setListViewHeightBasedOnChildren方法：

 sortListView.setAdapter(adapter); 2 LvHeightUtil.setListViewHeightBasedOnChildren(sortListView); 

　　

public static void setListViewHeightBasedOnChildren(ListView listView) {
ListAdapter listAdapter = listView.getAdapter();
if (listAdapter == null) {
return;
}
int totalHeight = 0;
for (int i = 0; i < listAdapter.getCount(); i++) {
View listItem = listAdapter.getView(i, null, listView);
listItem.measure(0, 0);
totalHeight += listItem.getMeasuredHeight();
}

ViewGroup.LayoutParams params = listView.getLayoutParams();
params.height = totalHeight
+ (listView.getDividerHeight() * (listAdapter.getCount() - 1));
listView.setLayoutParams(params);
}
