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", "[email protected]"};
DeveloperInfoAdapter developerAdapter = new DeveloperInfoAdapter(this, keys, titles, vals);
lst_developer.setOnclickLinstener(developerAdapter.myOnClickListener);
lst_developer.setAdapter(developerAdapter);
