android自动计算高度的listview 嵌套在ScrollView中使用

public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {

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

}

public class MylistView extends ListView {

public MylistView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
// TODO Auto-generated constructor stub
}
public MylistView(Context context, AttributeSet attrs) {
super(context, attrs);
// TODO Auto-generated constructor stub
}
public MylistView(Context context) {
super(context);
// TODO Auto-generated constructor stub
}

public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {

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

}
}

public class MyGridview extends GridView {

public MyGridview(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
// TODO Auto-generated constructor stub
}

public MyGridview(Context context, AttributeSet attrs) {
super(context, attrs);
// TODO Auto-generated constructor stub
}

public MyGridview(Context context) {

// TODO Auto-generated constructor stub
}

@Override

int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE>>2,
MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, expandSpec);}
}
