尝试这个：

private class DBHelper extends SQLiteOpenHelper{

private Context context;

public DBHelper(Context context, String name, CursorFactory factory, int version) {
  super(context, name, factory, version);
  this.context = context;
}

// Create DB and insert data
@Override
public void onCreate(SQLiteDatabase db) {
    db.execSQL(DB_CREATE);
    ContentValues cv = new ContentValues();
    cv.put(COLUMN_EX_NAME, "TITLE NAME");
    cv.put(COLUMN_EX_IMG,  R.drawable.ex_pic3);
    cv.put(COLUMN_EX_TYPE,  0);
    cv.put(COLUMN_EX_DESCRIPTION, context.getString(R.string.test));

}
