별도의 클래스에있는 Access ArrayList는 BroadcastReceiver에 의해 확장됩니다.

Question

저는 별도의 클래스에서 arrayList에 액세스해야하는 프로젝트를 개발하고 있습니다. 내가 NumberListActivity 활동을 어디서 목록을 만들고, BroadcastReceiver에 의해 확장됩니다 SmsLock 클래스에서이 목록을 acess 싶습니다. SmsLock 클래스에서 ArrayAdapter를 초기화하고 해당 목록을 ArrayAdapter에 할당합니다. 그러나 문제가 발생합니다. 어느 누구도 도와주세요.
List Class is 여기입니다.
NumberListActivity.java

public class NumberListActivity extends Activity { 
    SharedPreferences preferences1; 
    SharedPreferences.Editor spEditor1; 
    int count1 = 0; 
    ListView numList1; 
    Button btnAdd1; 
    public static ArrayList<String> list1 = new ArrayList<String>(); 
    public ArrayAdapter<String> adapter1; 
    public static final String Place1 = "placeKey"; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     // TODO Auto-generated method stub 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.sms_list); 

     preferences1 = getSharedPreferences("Place1", Context.MODE_PRIVATE); 
     spEditor1 = preferences1.edit(); 
     count1 = preferences1.getInt("count1", 0); 
     if (count1 > 0) { 
      for (int i = 0; i < count1; i++) { 
       list1.add(preferences1.getString("Value1[" + i + "]", "")); 
      } 
     } 
     final EditText edit = (EditText) findViewById(R.id.Item); 

     numList1 = (ListView) findViewById(R.id.Smslist); 
     btnAdd1 = (Button) findViewById(R.id.Add); 
     adapter1 = new ArrayAdapter<String>(this, 
       android.R.layout.simple_list_item_1, list1); 
     numList1.setAdapter(adapter1); 
     numList1.setOnItemClickListener(new OnItemClickListener() { 

      @Override 
      public void onItemClick(AdapterView<?> parent, View view, 
        int position, long id) { 
       // TODO Auto-generated method stub 
       count1 = preferences1.getInt("count1", 0); 
       // if (count > 0) { 
       for (int i = position; i < count1; i++) { 
        // list.add(); 
        if (i < count1) 
         spEditor1.putString(
           "Value1[" + i + "]", 
           preferences1.getString("Value1[" + (i + 1) 
             + "]", "")); 
        spEditor1.commit(); 

       } 
       // } 
       list1.remove(position); 

       count1 -= 1; 
       spEditor1.putInt("count1", count1); 
       spEditor1.commit(); 
       // preferences.edit().remove(position); 
       adapter1.notifyDataSetChanged(); 

      } 
     }); 
     btnAdd1.setOnClickListener(new OnClickListener() { 

      @Override 
      public void onClick(View v) { 
       // TODO Auto-generated method stub 
       // EditText edit = (EditText) findViewById(R.id.txtItem); 
       spEditor1.putString("Value1[" + count1 + "]", edit.getText() 
         .toString()); 
       spEditor1.commit(); 
       list1.add(preferences1.getString("Value1[" + count1 + "]", "")); 
       count1 += 1; 
       spEditor1.putInt("count1", count1); 
       spEditor1.commit(); 
       adapter1.notifyDataSetChanged(); 

      } 
     }); 
    } 

}  

내가이 클래스
SmsLock.java

public class SmsLock extends BroadcastReceiver { 
    final SmsManager sms = SmsManager.getDefault(); 
    Context c; 
    String phoneNumber; 
    String senderNum; 
    EditText my; 
    ArrayAdapter<String> adapter = new ArrayAdapter<String>(c, 
      android.R.layout.simple_list_item_1, NumberListActivity.list1); 

    @Override 
    public void onReceive(Context context, Intent intent) { 

     final Bundle bundle = intent.getExtras(); 
     try { 

      Toast.makeText(context, adapter.getCount() + "", Toast.LENGTH_LONG) 
        .show(); 

      if (bundle != null) { 

       final Object[] pdusObj = (Object[]) bundle.get("pdus"); 

       for (int i = 0; i < pdusObj.length; i++) { 

        SmsMessage currentMessage = SmsMessage 
          .createFromPdu((byte[]) pdusObj[i]); 
        phoneNumber = currentMessage.getDisplayOriginatingAddress(); 

        senderNum = phoneNumber; 
        String message = currentMessage.getDisplayMessageBody(); 
       } 

       for (int i = 0; i < adapter.getCount(); i++) { 
        if (senderNum.contains(adapter.getItem(i))) { 
         abortBroadcast(); 
        } 
       } 

      } // bundle is null 

     } catch (Exception e) { 
      Log.e("SmsReceiver", "Exception smsReceiver" + e); 

     } 
    } 

}

감사합니다. 이 방법이 가능 여부 될 경우

Answer 1

나는 단서가 없다,하지만 당신은 시도 할 수 두 가지가있다 :

1.Create 싱글 클래스 위치를 get 및 set ArrayList에. 클래스는 다음과 같습니다

Class MySingletonClass { 
    private static MySingletonClass obj = new MySingletonClass(); 
    private static ArrayList<String> listHere; 

    public MySingletonClass getInstance() { 
     return obj; 
    } 

    // getters and setters for listHere. 
} 

당신이 쓸 수있는 목록에 액세스하려면

MySingletonClass.getInstance().getListHere(); 

getListHere는 getter 메소드의 이름이고 그것을 설정 얻기 전에. 그렇지 않으면 NPE이 표시 될 수 있습니다.

또한 수신자가 목록이 채워지기 전에 시작될 수 있습니다. 따라서 항상 사용하기 전에 null을 확인하십시오.

2. 다른 옵션은 당신이 그것을 사용하기 전에, 심지어 방송 수신기이 경우에 null에 대한

LruCache<String, Object> obj = ... // create a new obj (again in a singleton class) 
obj.put("keyhere", list_obj_here); 

확인과 같은 캐시 개체의 목록을 저장합니다.
