我正在尝试通过Android / JSOUP从一个表中提取以下数据,但是我在确定这个过程时遇到了一些麻烦。我想我已经能够使用下面提供的代码来实现这一点了--但是由于某些原因,我仍然无法让我的文本视图显示任何表数据。
附注:
如有必要,可提供实时URL。
来源:
public class MainActivity extends Activity {
TextView tv;
final String URL = "http://exampleurl.com";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tv = (TextView) findViewById(R.id.TextView01);
new MyTask().execute(URL);
}
private class MyTask extends AsyncTask<String, Void, String> {
ProgressDialog prog;
String title = "";
@Override
protected void onPreExecute() {
prog = new ProgressDialog(MainActivity.this);
prog.setMessage("Loading....");
prog.show();
}
@Override
protected String doInBackground(String... params) {
try {
Document doc = Jsoup.connect(params[0]).get();
Element tableElement = doc.getElementsByClass("datagrid")
.first();
title = doc.title();
} catch (IOException e) {
e.printStackTrace();
}
return title;
}
@Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
prog.dismiss();
tv.setText(result);
}
}
}表:
<table class="datagrid">
<tbody><tr>
<th>Item No.</th>
<th>Name</th>
<th>Sex</th>
<th>Location</th>
</tr>
<tr>
<td><a href="redirector.cfm?ID=a33660a3-aae0-45e3-9703-d59d77717836&page=1&&lname=&fname=" title="501207593">501207593 </a></td>

您的表没有标题。尝试使用Jsoup在TextView中获取一些文本:
try {
Document doc = Jsoup.connect(params[0]).get();
Element tableElement = doc.select(".datagrid");
Element th = doc.select("tr").first;
Element firstTh = th.select("th").first();
title = firstTh.text();

我觉得这条线
Element th = doc.select("tr").first;相反,它应该写成
Element th = doc.select("tr").first(); https://stackoverflow.com/questions/19122596
