我正在构建一个个人应用程序,使用JSOUP将某些链接的文本放入ListView。对于每个链接,ListView中应该有一个相应的条目,其中包含该链接的文本。当我运行应用程序时,它成功解析了所有这些文本。但是,它将所有文本放在一起放在一个ListView条目中,然后对连续输入执行完全相同的操作。我哪里错了?相关代码如下:
public class MainActivity extends Activity {
public Elements beer;
public ArrayList<String> beerList = new ArrayList<String>();
private ArrayAdapter<String> adapter;
private ListView lv;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
lv = (ListView) findViewById(R.id.listView1);
new NewThread().execute();
adapter = new ArrayAdapter<String>(this, R.layout.simple_list_item_1, R.id.beer_name, beerList);
}
public class NewThread extends AsyncTask<String, Void, String> {
@Override
protected String doInBackground(String... arg) {
Document doc;
try {
doc = Jsoup.connect("URLURLURLURL").userAgent("Mozilla/5.0 (Windows NT 6.1; WOW64; rv:5.0) Gecko/20100101 Firefox/5.0").get();
beer = doc.select("a[href*=URL.com/URL/]");
beerList.clear();
for (Element beers : beer) {
beerList.add(beer.text());
}
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
@Override
protected void onPostExecute(String result) {
lv.setAdapter(adapter);
}
}
}
我目前得到的内容的直观表示:

答案 0 :(得分:1)
更改
for (Element beers : beer) {
beerList.add(beer.text());
}
到
for (Element beers : beer) {
beerList.add(beers.text()+"\n");
}
你想念啤酒中的 s
试试这个
public class MainActivity extends Activity {
public Elements beer;
public ArrayList<String> beerList = new ArrayList<String>();
private ArrayAdapter<String> adapter;
private ListView lv;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
lv = (ListView) findViewById(R.id.listView1);
new NewThread().execute();
adapter = new ArrayAdapter<String>(this, R.layout.simple_list_item_1, R.id.beer_name, beerList);
}
public class NewThread extends AsyncTask<String, Void, String> {
@Override
protected String doInBackground(String... arg) {
Document doc;
try {
doc = Jsoup.connect("URLURLURLURL").userAgent("Mozilla/5.0 (Windows NT 6.1; WOW64; rv:5.0) Gecko/20100101 Firefox/5.0").get();
beer = doc.select("a[href*=URL.com/URL/]");
beerList.clear();
for (Element beers : beer) {
beerList.add(beers.text()+"\n");
}
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
@Override
protected void onPostExecute(String result) {
lv.setAdapter(adapter);
}
}
}
