无法将整数类型插入到DB中

我在DB中使用整数时遇到问题。我在这里创建了一个SQLiteOpenHelper

将对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);

        }

编辑: 我添加了insertRecord()来显示出现问题的步骤:

 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);

        }

尝试插入后记录输出:

最后一个变量出现问题。我们可以把KEY_EXR; KEY_WGHT但不是KEY_REP。如果我只将KEY_REP列更改为VARCHAR,那么我可以向该行添加数据。我可能在创建表格时犯了错误。

2 个答案:

答案 0 :(得分:0)

对于非空字段,也请指定默认值。 此外,根据崩溃报告,还有数字格式例外。检查Integer.parseInt(repetition.toString()),很可能重复不是数值。

答案 1 :(得分:-1)

请在insertRecord()方法中注释行:

// values.clear();

因为它从值列表中清除了您的值,并且它不会更新表中的新行。
