public class Schedule extends Activity{
 
 private DbAdapter mDbHelper;
 Cursor mCursor;
 
 @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.schedule);
        
        mDbHelper = new DbAdapter(this);
        mDbHelper.open();
        mDbHelper.insertRow("today", 1897);
        long rowid = mDbHelper.insertRow("today", 45675);
        
        Toast.makeText(getApplicationContext(), "ok" , Toast.LENGTH_LONG ).show(); //확인용
  
        /*
        mCursor = mDbHelper.fetchAllRows();
        startManagingCursor(mCursor);
        SimpleCursorAdapter adapter = new SimpleCursorAdapter(
         this, 
         R.layout.schedule,
        mCursor,
        new String[] { "Day","Cal"},
        new int[] { R.id.text1, R.id.text2 }  );
        setListAdapter(adapter);

        if (mDbHelper != null) mDbHelper.close(); 
        */
}

 

위의 코드와 같이 Activity를 상속받아서 fetchallrows부분을 주석처리해주면 app구동에 문제가 없습니다.

하지만 db의 내용을 listadapter에 받아와서 list로 뿌려줄려고 하는데

여기서 listactivity를 상속받아서 저 주석문을 풀고 실행을 하면 어플이 죽어버립니다.

ui 구성은 탭호스트를 이용하였고 그 탭을 클릭시에 schedule class가 실행됩니다.
