ScrollView和ListView冲突解决



直接上代码来的直接点吧……

package com.zhuo.scrollview_listview;

import java.util.ArrayList;

import android.app.Activity;
import android.os.Bundle;
import android.view.MotionEvent;
import android.widget.AbsListView;
import android.widget.AbsListView.OnScrollListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.ScrollView;

public class MainActivity extends Activity {

 private ListView listView;
 private ScrollView scrollView;
 private ArrayAdapter adapter;

 /**
  * 标记:ListView中的Item是否滑动到底端.
  */
 private boolean isListViewMoveToBottom = false;
 /**
  * 表示是否可以滑动ScrollView.(当 isListViewMoveToBottom = true,分发事件给它滑动ScrollView.)
  */
 private boolean isScrollViewMoved = false;

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  scrollView = (ScrollView) this.findViewById(R.id.scrollView);
  listView = (ListView) this.findViewById(R.id.listview);

  adapter = new ArrayAdapter(this,
    android.R.layout.simple_list_item_1, getData());
  listView.setAdapter(adapter);
  listView.setOnScrollListener(new OnScrollListener() {

   @Override
   public void onScrollStateChanged(AbsListView view, int scrollState) {

    // 表示用户将ListView中的Item滑动到底端.

    switch (scrollState) {
    // the user is scrolling using touch,and their finger is still
    // on the screen.
    case OnScrollListener.SCROLL_STATE_TOUCH_SCROLL:

     break;
    // the view is not scrolling .
    case 0:
     if (isListViewMoveToBottom) {
      // 表示ScrollView可以获取滑动事件.
      isScrollViewMoved = true;
     } else {
      isScrollViewMoved = false;
     }
     break;
    }
   }

   @Override
   public void onScroll(AbsListView view, int firstVisibleItem,
     int visibleItemCount, int totalItemCount) {

    if ((firstVisibleItem + visibleItemCount) == totalItemCount) {
     // 表示ListView中所有Item已经滑动到ListView的底端.(在向同一个方向滑动，则应该ScrollView滑动.)
     isListViewMoveToBottom = true;

    } else {
     isListViewMoveToBottom = false;
    }
   }
  });
 }

 private ArrayList getData() {
  ArrayList dataArrayList = new ArrayList();
  for (int i = 0; i <30; i++) {
   dataArrayList.add("xxx:" + i);
  }
  return dataArrayList;
 }

 @Override
 public boolean dispatchTouchEvent(MotionEvent ev) {
  if (ev.getAction() == MotionEvent.ACTION_MOVE) {
   // 想让哪个控件先执行，直接调用。

   if (isScrollViewMoved) {
    // 将滑动事件分发给ScrollView.
    scrollView.dispatchTouchEvent(ev);
    // 释放到ScrollView获取的事件.(否则,会覆盖其子控件View的相同事件.)
    isScrollViewMoved = false;
   } else {
    // 分发事件给ListView,让点击ListView的时候，其可以滑动。
    listView.dispatchTouchEvent(ev);

   }
  }
  return super.dispatchTouchEvent(ev);
 }
}
