Scraped Data Not Printing - Android Studio

Question

Bir html dosyasından veri kazıyorum ve uygulamanızı çalıştırdığımda varsayılan ekran görünür. Bana jsoup belgesini okumamı söyleme, lütfen hepsini okuyun. Ekranda yazdırmak için nasıl herhangi bir fikir herkes?

import android.app.Activity; 
    import android.os.Bundle; 
    import java.io.File; 
    import java.io.IOException; 
    import org.jsoup.Jsoup; 
    import org.jsoup.nodes.Document; 
    import org.jsoup.nodes.Element; 
    import org.jsoup.select.Elements; 
    import android.widget.TextView; 

public class MainActivity extends Activity { 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    try { 
     File input = new File("C:\\Users\\user\\Desktop\\Mobile Newest\\JSoup\\app\\src\\main\\assets\\filename.html"); 
     Document doc = Jsoup.parse(input, "UTF-8"); 
     Elements tableElements = doc.select("td"); 
     TextView textView = (TextView)findViewById(R.id.text_view); 
     for (Element td : tableElements) { 
      textView.setText(td.text()); 
      System.out.println(td.text()); 
     } 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 

    //System.out.println("Testing"); 
}

Soruya verilen yorumlar:

TextView'a herhangi bir mesaj göstermek istiyorsanız, referans alın ve metni ayarlayın.

TextView textView = (TextView)findViewById(R.id.text_view); 

for (Element td : tableElements) { 
    textView.setText(td.text()); 
} 

senin TextView content_main yılında bir id tanımlayın:

<TextView 
    android:id="@+id/text_view" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" />
