尝试使用空格输入字符串时SQLite崩溃

Question

我正在创建一个应用程序，该应用程序具有存储其他表的应用程序，以便当您尝试将自己的输入放入应用程序时它将存储表，但当你尝试向默认表中添加一个表时，它完美地工作，除非有一个空间“测试”将完美工作“测试1”会使应用程序崩溃。这是我的代码检索由用户inputed字符串：

t = new Table(this); 
t.open(); 
final AlertDialog.Builder alert = new AlertDialog.Builder(this); 
final EditText input = new EditText(this); 
alert.setView(input); 
alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() { 
    public void onClick(DialogInterface dialog, int whichButton) { 
     rListName = input.getText().toString(); 
     t.createNew(rListName + "DB"); 
     t.createList(rListName, rListName + "DB"); 
     t.close(); 
    } 
}); 
alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() { 
    public void onClick(DialogInterface dialog, int whichButton) { 
     dialog.cancel(); 
    } 
}); 
alert.show(); 

这是我createNew和createList：

public void createNew(String TABLE_NAME){ 
if(DATABASE_STATUS == "new"){ 
    ourHelper.createNew(ourDatabase, TABLE_NAME); 
    System.out.println("Creating " + TABLE_NAME); 
}else{ 
    System.out.print("Already Created"); 
    } 
} 


public long createList(String listName, String listDB){ 
    ContentValues cv = new ContentValues(); 
    cv.put(KEY_LISTNAME, listName); 
    cv.put(KEY_LISTDB, listDB); 
    return ourDatabase.insert(DEFAULT_TABLE, null, cv); 
} 

我createNew（）被执行，以使新表

public void createNew(SQLiteDatabase db, String TABLE_NAME){ 
    db.execSQL("CREATE TABLE " + TABLE_NAME + " (" + 
    KEY_ROWID + " INTEGER PRIMARY KEY AUTOINCREMENT, " + 
    KEY_QUESTION + " TEXT NOT NULL, " + 
    KEY_PATH + " TEXT NOT NULL);" 
    ); 
} 

最后但并非租借，我的logcat：

Answer 1

如果你真的想要空格，你需要在你的表名中加上引号，这样它的“test 1”。但是，这通常是一个坏主意，我会用下划线替换空格，以便它变成test_1。
