onclick에서 앱이 다운 됨

Question

내 numbersIntent 청취자를 클릭하여 내 NumbersActivity 클래스 파일을 열면 내 Android 앱이 다운됩니다.

나는 문자열을 while 루프를 사용하여 할당하려면 NumbersActivity 클래스 파일에 설정된 arraylist 이름 "단어"를 사용하고 있습니다.

NumbersActivity 클래스 파일을 제외한 다른 클래스는 괜찮아 보입니다. 나는 이유를 알 수 없다. 아무도 도와 줄 수 있니? 여기

package com.example.android.miwok; 

import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 

import android.widget.LinearLayout; 
import android.widget.TextView; 

import java.util.ArrayList; 

public class NumbersActivity extends AppCompatActivity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_numbers); 

     ArrayList<String> words = new ArrayList<String>(); 
     words.add("One"); 
     words.add("Two"); 
     words.add("three"); 
     words.add("Four"); 
     words.add("Five"); 
     words.add("Six"); 
     words.add("Seven"); 
     words.add("Eight"); 
     words.add("Nine"); 
     words.add("Ten"); 

     LinearLayout rootView = (LinearLayout) findViewById(R.id.rootView); 
     int index = 0; 
      while (index < words.size()); 
     { 

      TextView wordView = new TextView(this); 
      wordView.setText(words.get(index)); 
      rootView.addView(wordView); 
index++; 

     } 

    } 

}

Answer 1

당신이 코드 행 다음에있다 : 것을 제거

while (index < words.size()); 

시도 ";" 운영자의 말에은 다음과 같이해야한다 : 동일 또는 해당 ID를 가진 다른 레이아웃에보기가 아니라면

while (index < words.size()) 

Answer 2

편집 대답하여 NumbersActivity에서

protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     View view = getLayoutInflater().inflate(R.layout.activity_numbers, null); 
     setContentView(view); 

     ArrayList<String> words = new ArrayList<String>(); 
     words.add("One"); 
     words.add("Two"); 
     words.add("three"); 
     words.add("Four"); 
     words.add("Five"); 
     words.add("Six"); 
     words.add("Seven"); 
     words.add("Eight"); 
     words.add("Nine"); 
     words.add("Ten"); 

     int index = 0; 
     while (index < words.size());{ 
      TextView wordView = new TextView(this); 
      wordView.setText(words.get(index)); 
      view.addView(wordView); 
      index++; 
     }
