原文地址：Android: 如何实现ScrollView中含有ListView?作者：mailofzxf

ListView本身就含有ScrollView，因此把ListView放到ScrollView中会引起混乱（谁来响应滑动事件？）但有时又确有此需求，以实现ListView的内容连同其他内容的滚动。

要想把ListView嵌入ScrollView,有二个方法：

方法1：整体上使用一个ListView, 把不需滚动的部分放入ListView的Header或Footer中。
注意: 一定要先添加HearderView和FooterView,然后再设置ListView的Adapter.
缺陷: Header或Footer中的内容不能滚动；并且只能允许同时存在一个ListView。
代码如下:

LayoutInflater mLI =
           (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

listView = (ListView) findViewById(R.id.listView);
     datas = new ArrayList<Object>();
     fillDatas();
     datasAdapter = new DemoListAdapter(context, datas);
     MyListHeaderView headerView = mLI.inflate(R.layout.my_header_layout, null);
     FillDataToHeaderView(headerView);
     MyListFooterView footerView = mLI.inflate(R.layout.my_footer_layout, null);
     FillDataToFooterView(footerView);

listView.addHeaderView(headerView); 
     listView.addFooterView(footerView);
     listView.setAdapter(datasAdapter);
 
方法2：用LinearLayout模拟ListView, 从而实现任意内容的滚动。
下面实现的是一个通用的LinearLayoutForListView，可以为它设置不同的Adapter从而显示不同的数据。
LinearLayoutForListView的代码如下:

public class LinearLayoutForListView extends android.widget.LinearLayout {
    static final String LOG_TAG = "LinearLayoutForListView";
    private android.widget.BaseAdapter adapter;
    private OnClickListener onClickListener = null;

public void fillLinearLayout() {
        int count = adapter.getCount();
        for (int i = 0; i < count; i++) {
            View v = adapter.getView(i, null, null);
            v.setOnClickListener(this.onClickListener);
            addView(v, i);
        }
        Log.v("countTAG", "" + count);
    }

public LinearLayoutForListView(Context context) {
        super(context);
    }

public LinearLayoutForListView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

public android.widget.BaseAdapter getAdpater() {
        return adapter;
    }

public void setAdapter(android.widget.BaseAdapter adpater) {
        this.adapter = adpater;
        fillLinearLayout();
    }

public OnClickListener getOnclickListner() {
        return onClickListener;
    }

public void setOnclickLinstener(OnClickListener onClickListener) {
        this.onClickListener = onClickListener;
    }
}

注意,上面LinearLayoutForListView的成员adapter是BaseAdapter，因此可以自定义其它的Adapter来加入数据。下面是一个Adapter的参考实现,用于显示一个软件开发者的联系信息：

public class DeveloperInfoAdapter extends BaseAdapter  {
    static final String LOG_TAG="DeveloperInfo";
    public final int VIEW_INDEX = 3000;
    private Context  mContext;
    private String[] mKeys;
    private String[] mTitles;
    private String[] mVals;
    LayoutInflater mLI = null;

public DeveloperInfoAdapter(Context context, String[] keys, String[] titles, String[] vals) {
        mContext = context;
        mKeys = keys;
        mTitles = titles;
        mVals = vals;
        mLI = (LayoutInflater)mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        // to Make sure mKeys(...) are NOT null:
        if(mKeys==null || mTitles==null || mVals==null) {
            mKeys = mTitles = mVals = new String[]{};
        }
    }
    
    @Override
    public int getCount() {
        return mKeys.length;
    }
    
    @Override
    public String getItem(int index) {
        if(index>=0 && index<mVals.length)
            return mVals[index];
        else
            return null;
    }
    
    @Override
    public long getItemId(int position) {
        return position;
    }
    
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
            if(position <0 || position > mKeys.length)
                return null;
            final String key = mKeys[position];
            final String title = mTitles[position];
            final String val = mVals[position];
            
            View v = convertView;
            if (v == null) {
                v = mLI.inflate(R.layout.dev_web_email_layout, null);
            }
            v.setId(position+VIEW_INDEX);
            v.setClickable(true);
            
            if (true) {
                TextView v_title = (TextView) v.findViewById(R.id.dev_title);
                TextView v_val = (TextView) v.findViewById(R.id.dev_val);
                v_title.setText(title);
                v_val.setText(val);
            }
            return v;
    }

private void callBrowser(String url){
        if(TextUtils.isEmpty(url))
            return;
        final String prefix = "http://";
        try {
            if(!url.startsWith(prefix))
                url = prefix + url;
            Uri uri = Uri.parse(url);
            Intent intent = new Intent(Intent.ACTION_VIEW, uri);
            mContext.startActivity(intent);
        } catch (Exception e) {
            String err_msg = e.getMessage();
            Log.d(LOG_TAG, "Uri err: " + err_msg);
        }
    }

private void callEmail(String emailbox){
        if(TextUtils.isEmpty(emailbox))
            return;
        final String prefix = "mailto:";
        try {
            if(!emailbox.startsWith(prefix))
                emailbox = prefix + emailbox;
            Uri uri = Uri.parse(emailbox);
            Intent intent = new Intent(Intent.ACTION_SENDTO, uri);
            mContext.startActivity(intent);
        } catch (Exception e) {
            String err_msg = e.getMessage();
            Log.d(LOG_TAG, "Uri err: " + err_msg);
        }
    }
    
    public android.view.View.OnClickListener myOnClickListener
                   = new android.view.View.OnClickListener() {
        @Override
        public void onClick(View v) {
            try {
                int id = v.getId();
                int position = id-VIEW_INDEX;
                if(position <0 || position > mKeys.length)
                    return;
                final String key = mKeys[position];
                final String title = mTitles[position];
                final String val = mVals[position];
                
                if("website".equals(key)) {
                    callBrowser(val);
                } else if("email".equals(key)) {
                    callEmail(val);
                }
            } catch (Exception e) {
                // Do nothing!
            }
        }        
    };
    
}

相关的layout文件部分如下：
            <TextView android:id="@+id/detail_developer"
                    android:layout_width="fill_parent"
                    android:layout_height="wrap_content"
                    android:text="@string/lbl_title_developer"
                    android:textStyle="bold"
                    android:background="#008F00"
                    >
            </TextView>
            <com.xxx.yyy.LinearLayoutForListView android:id="@+id/detail_lst_web_email"
                android:orientation="vertical"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:visibility="visible"
                android:clickable="true"
                >
            </com.xxx.yyy.LinearLayoutForListView>

以下代码向这个假的ListView填入数据：
        com.xxx.yyy.LinearLayoutForListView lst_developer
               = (com.xxx.yyy.LinearLayoutForListView) findViewById(R.id.detail_lst_web_email);
        String keys[]={ "website", "email"};
        String titles[]={getResources().getString(R.string.lbl_title_developer_website),
                         getResources().getString(R.string.lbl_title_developer_email)};
        String vals[]={"http://abc.com", "abc@def.com"};
        DeveloperInfoAdapter developerAdapter = new DeveloperInfoAdapter(this, keys, titles, vals);
        lst_developer.setOnclickLinstener(developerAdapter.myOnClickListener);
        lst_developer.setAdapter(developerAdapter);
