解决ScrollView中listview、gridview的嵌套问题

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);

}

}
