关于ScrollView和listview的冲突关于的滑动和宽度

listview和ScrollView嵌套有两个冲突，关于listview显示不全的问题和listview和scrollview的滑动冲突

自定义listview

package com.exmple.listscrow;

import android.content.Context;

import android.util.AttributeSet;

import android.view.MotionEvent;

import android.widget.ListView;

public class MyListView extends ListView {

	int mLastMotionY;

	boolean bottomFlag;

	public MyListView(Context context, AttributeSet attrs) {

		super(context, attrs);

		// TODO Auto-generated constructor stub

	}

//解决宽度的冲突

	@Override

	protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { // 对height重新赋值

																			// heightMeasureSpec

																			// =

		heightMeasureSpec = MeasureSpec.makeMeasureSpec(500/*

															 * Integer.MAX_VALUE

															 * >> 2

															 */,

				MeasureSpec.AT_MOST);

		super.onMeasure(widthMeasureSpec, heightMeasureSpec);

	}
解决滑动的冲突
	@Override

	public boolean dispatchTouchEvent(MotionEvent ev) {

		getParent().requestDisallowInterceptTouchEvent(true);

		return super.dispatchTouchEvent(ev);

	}

}

　　在主方法里贴以下代码，以下这个代码可以实现以下效果，当listview滑到底部的时候，

ScrollView会和listview实现连动
package com.exmple.listscrow;

import java.util.ArrayList;

import java.util.List;

import com.exaple.vo.Super;

import android.R.fraction;

import android.os.Bundle;

import android.app.Activity;

import android.view.Menu;

import android.view.MotionEvent;

import android.view.View;

import android.view.View.OnTouchListener;

import android.widget.AbsListView;

import android.widget.AbsListView.OnScrollListener;

import android.widget.ListView;

import android.widget.ScrollView;

import android.widget.Toast;

public class MainActivity extends Activity implements OnScrollListener {

	String[] name = new String[] { "陈克", "陈多多", "张小杰", "张杰", "宋静萌", "郑芳蓓",

			"杨洋", "谢娜", "刘忠杰", "天下", "走路去纽约", "一切都值得", "最美的太阳", "我们都一样",

			"娜样纯洁的爱恋", "一切都值得", "最美的太阳", "我们都一样", "娜样纯洁的爱恋" };

	String[] price = new String[] { "1", "1", "1", "1", "1", "1", "1", "1",

			"1", "1", "1", "1", "1", "1", "1", "1", "1", "1", "1" };

	private List<Super> list;

	boolean island;

	private MyListView listview;

	private ScrollView sc;

	@Override

	protected void onCreate(Bundle savedInstanceState) {

		super.onCreate(savedInstanceState);

		setContentView(R.layout.activity_main);

		listview = (MyListView) findViewById(R.id.listview);

		sc = (ScrollView) findViewById(R.id.sc);

		getData();

		Apap ap = new Apap(list, MainActivity.this);

		listview.setAdapter(ap);

		listview.setOnScrollListener(this);

		//不用自定义listview时用

		/*listview.setOnTouchListener(new OnTouchListener() {

			@Override

			public boolean onTouch(View v, MotionEvent event) {

				if (event.getAction() == 2) {

					sc.requestDisallowInterceptTouchEvent(true);

				} else {

					sc.requestDisallowInterceptTouchEvent(false);

				}

				return false;

			}

		});

*/

		// listview.getParent().requestDisallowInterceptTouchEvent(false);

	}

	public List<Super> getData() {

		list = new ArrayList<Super>();

		for (int i = 0; i < name.length; i++) {

			Super super1 = new Super();

			super1.setName(name[i]);

			list.add(super1);

		}

		return list;

	}

	//

	@Override

	public void onScrollStateChanged(AbsListView view, int scrollState) {

		if (island && scrollState == OnScrollListener.SCROLL_STATE_TOUCH_SCROLL) {

			Toast.makeText(MainActivity.this, "kaisjia", 0).show();

			sc.requestDisallowInterceptTouchEvent(false);

		}

	}

	@Override

	public void onScroll(AbsListView view, int firstVisibleItem,

			int visibleItemCount, int totalItemCount) {

		island = (firstVisibleItem + visibleItemCount) == totalItemCount;

	}

}
