有什么办法中显示类似名称
TechCrunch的
蠢
美国航空航天局
在列表视图,当用户点击其中一个,就应该打开的链接,相应的上市网站的意图。
Is there any way in to Show Names like
"TechCrunch"
"Twit"
"NASA"
in the listview and when the user clicks on one of them , it should open an intent with the link for corresponding Websites listed.
任何想法AP preciated。
Any ideas appreciated.
如果您不希望的ListView
是由数据库生成的,你要添加的每个网站上的的ListView的适配器
自己,那么你可以做到以下几点。
If you don't want the ListView
to be generated by a database and you want to add every website to the adapter of your ListView
yourself, then you can do the following.
您需要创建一个项目
类,如下所示:
You would have to create an Item
class, that looks like this:
public class Item {
private String mName;
private int mLink;
public Item(String name, int link) {
this.mName = name;
this.mLink = link;
}
public int getLink() {
return mLink;
}
public void setLink(int link) {
this.mLink = link;
}
public String getName() {
return mName;
}
public void setName(String name) {
this.mName = name;
}
@Override
public String toString() {
return this.mName;
}
}
,然后设置你的ListView的适配器是这样的:
and then set the adapter of your ListView like this:
List<Item> dataForTheAdapter = new ArrayList<Item>();
// add some data
dataForTheAdapter.add(new Item("Apple", "www.Apple.com"));
dataForTheAdapter.add(new Item("Microsoft", "www.Microsoft.com"));
dataForTheAdapter.add(new Item("Google", "www.Google.com"));
mContext = MyActivity.this;
// R.layout.row is a layout, that contains only one TextView
mAdapter = new ArrayAdapter<Item>(mContext, R.layout.row, dataForTheAdapter);
ListView listView = (ListView) findViewById(R.id.listView);
listView.setAdapter(mAdapter);
现在设置 OnItemClickListener
您的ListView
。
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
String url = mAdapter.getItem(position).getLink();
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i);
}
});
