無法將整數類型插入到數據庫中

我在使用數據庫中的整數時遇到問題。我有一個SQLiteOpenHelper這裏我創建無法將整數類型插入到數據庫中

將對DBAdapter：

public static final String KEY_ROWID="id"; 
public static final String KEY_EXR="name"; 
public static final String KEY_WGHT="weight"; 
public static final String KEY_REP="repetition"; 
public static final String KEY_DATE="duedate"; 
final static String[] columns = {KEY_ROWID, KEY_EXR, KEY_WGHT, KEY_REP}; 



    final static String DATABASE_NAME = "ExerciseDB"; 
final static String DATABASE_TABLE = "exercisetb"; 
final static int DATABASE_VERSION = 2; 


//DBAdapter için Loglar 

private static final String TAG = "DBAdapter"; 



private static final String DATABASE_CREATE = 
     "create table if not exists exercisetb (id integer primary key autoincrement, " 
       + "name VARCHAR not null, weight VARCHAR not null, repetition integer not null);";

插入：

public long insertRecord() { 


      ContentValues values = new ContentValues(); 

      values.put(DBAdapter.KEY_EXR, name.toString()); 

      values.put(DBAdapter.KEY_WGHT, weight.toString(); 

      values.put(DBAdapter.KEY_REP, Integer.parseInt(repetition.toString())); 
      values.clear(); 

      return mDbHelper.getWritableDatabase().insert(DBAdapter.DATABASE_NAME, null, values); 

     }

編輯：我加insertRecord（）來顯示哪個步驟出現問題：

public long insertRecord() { 


      ContentValues values = new ContentValues(); 

      values.put(DBAdapter.KEY_EXR, name.toString()); 
      Log.i(TAG,"Name field assign."); 

      values.put(DBAdapter.KEY_WGHT, Integer.parseInt(weight.toString())); 
      Log.i(TAG,"weight assisgn."); 
      values.put(DBAdapter.KEY_REP, Integer.parseInt(repetition.toString())); 
      Log.i(TAG,"repetition field assign."); 
      values.clear(); 

      return mDbHelper.getWritableDatabase().insert(DBAdapter.DATABASE_NAME, null, values); 

     }

嘗試插入後的日誌輸出：

04-07 15:23:25.217 3442-3442/com.example.alperen.exercisem I/addnew﹕ OnClick'e girildi

      at java.lang.Integer.parseInt(Integer.java:331) 
      at com.example.alperen.exercisem.Addnew$1.insertRecord(Addnew.java:69)

問題發生在最後一個變量上。我們可以把KEY_EXR; KEY_WGHT，但不是KEY_REP。如果我只將KEY_REP列更改爲VARCHAR，那麼我可以將數據添加到該行。我在創建表格時可能會犯錯。

您試圖插入哪個**整數**？ –

你有錯誤嗎？結果是什麼？ – niyou
