解决ScrollView和ListView冲突的几个方案

http://www.apkbus.com/android-161576-1-1.html

我用的第四种。

package com.qiubaiclient.customui;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);}@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);}}

因此再我的客户端中，现实评论这一部分就使用了这个方案。

先上截图。

这里使用了大神的库：

地址:http://www.trinea.cn/android/android-common-lib/

同时改动了一些代码。

修改点

遇到的问题：

1. 刚进入画面我需要立即刷新数据。
2. 再原代码中点击加载更多后滚动条没有显示，并且界面卡顿了。

于是我直接再外部调用了，

onBottom()它会底部注册的监听回调到onClick

/** * on bottom loading, you can call it by manual, but you should manual call * onBottomComplete at the same time. */public void onBottom() {if (isOnBottomStyle && !isOnBottomLoading) {isOnBottomLoading = true;onBottomBegin();footerButton.performClick();}}

另外，

// 设置末尾点击加载跟多forScrollView.setOnBottomListener(new OnClickListener() {@Overridepublic void onClick(View view) {// TODO Auto-generated method stub// 获取数据之前先检查网络是否可用if (Common.isNetConnected(CommentsActivity.this)) {forScrollView.onBottomBegin();page.addPage();getCommentsData();} else {ToastUtil.show(CommentsActivity.this,"当前网络不可用，建议检查网络连接状态。", Toast.LENGTH_SHORT);mHandler.sendEmptyMessage(MyHandlerThread.RESET_STATUS);}}});

显示调用

forScrollView.onBottomBegin();

这样就可以显示滚动条。

第三，并添加了下面的代码解决ScrollView和ListView的冲突问题。

@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);}
