###重写listview,使其嵌套scrollview

import android.content.Context;
import android.util.AttributeSet;
import android.widget.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);
	}

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