带有网络视图的列表视图 [英] Listview with webview
问题描述
我正在尝试创建一个带有 Webview 的 ListView,但该应用程序没有显示任何内容.这是我的代码:
i'm trying to create a ListView with a Webview inside, but the app shows nothing. Here my Code:
我设置 CustomAdapter 的 MainActivity
The MainActivity where I set the CustomAdapter
public class Web_in_list1Activity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ListView lv = (ListView)findViewById(R.id.listView2);
ListViewAdapter adapter = new ListViewAdapter(this);
lv.setAdapter(adapter);
}
}
自定义适配器的getView在这里,我获取了 ListView 的布局并获取了 Webview 的 URL
getView of the CustomAdapter Here I get the Layout for the ListView and ste the URL for the Webview
public View getView(int arg0, View convertView, ViewGroup arg2) {
// TODO Auto-generated method stub
LayoutInflater inflater = context.getLayoutInflater();
convertView = inflater.inflate(R.layout.listitem, null);
WebView wv = (WebView)convertView.findViewById(R.id.webview);
wv.getSettings().setJavaScriptEnabled(true);
wv.loadUrl("http://www.google.com");
convertView.setTag(wv);
return convertView;
}
main.xml

android:layout_height="fill_parent"
android:layout_width="fill_parent"

推荐答案

你不能把可滚动的东西可靠地放在其他可滚动的东西里面.因此,您不能可靠地:
You cannot reliably put scrollable things inside of other scrollable things. Hence, you cannot reliably:
- 在
ListView
行中放置一个WebView
- 在
ListView
行中放置一个ScrollView
- 将
WebView
放入ScrollView
- 将
ListView
放入ScrollView
- Put a
WebView
in aListView
row - Put a
ScrollView
in aListView
row - Put a
WebView
in aScrollView
- Put a
ListView
in aScrollView
此外,WebView
是一个非常重量级的小部件,并没有设计成有大量的副本.请考虑使用 TextView
进行轻量级 HTML 渲染.
Moreover, a WebView
is a very heavyweight widget and is not designed to have lots of copies floating around. Please consider using TextView
for lightweight HTML rendering.
