Question

我正在创建一个具有默认表的应用程序，该表存储其他表的内容，以便当您尝试将自己的输入放入应用程序时，它将存储表，但是当您尝试将表添加到默认表时除非有一个空间“测试”将完美“测试1”将使应用程序崩溃，它的工作完美。这是我的代码检索用户输入的字符串：

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();

这是我的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);
}

为执行新表而执行的createNew（）

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);"
    );
}

最后但不是租约，我的logcat：

Answer 1

如果你真的想要空格，你需要在表名周围加上引号，使其为“test 1”。然而，这通常是一个坏主意，我会用下划线替换空格，因此它变为test_1。

尝试输入带空格的String时，SQLite崩溃
