Document doc = null; 
     try {

XML이 주요 활동

<?xml version="1.0" encoding="utf-8"?> 
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto"

    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    tools:context="com.example.krzych.taksometr.MainActivity"> 

    <TextView 
     android:id="@+id/tekst" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="Hello World!"

     app:layout_constraintLeft_toLeftOf="parent" 
     app:layout_constraintRight_toRightOf="parent" 
     app:layout_constraintTop_toTopOf="parent" /> 

</android.support.constraint.ConstraintLayout>

이 나를 위해 작동합니다

button.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      new JsoupParser().execute(); 

     } 

    }); 
} 
public class JsoupParser extends AsyncTask<String,Integer,String> { 
    String title; 
    String s = editText.getText().toString();//get url from EditText 
    Document doc; 

    @Override 
    protected void onPreExecute() { 
     super.onPreExecute(); 
     textView.setText(""); 
    } 

    @Override 
    protected String doInBackground(String... params) { 
     try { 
      doc = Jsoup.connect(s).get(); 
      title = doc.title(); 

      } 
     catch (IOException e) { 
      e.printStackTrace(); 
     } 
     return null; 
    } 

    @Override 
    protected void onPostExecute(String result) { 

     textView.setText(title); 
    }
