不兼容的类型:ArrayList无法转换为字符串

我没有看到我的 ArrayList 有什么问题，我收到了这个错误:

I don't see what is wrong with my ArrayList that i get this error:

错误:(133, 17) 错误:类型不兼容:ArrayList 不能为转换为字符串

Error:(133, 17) error: incompatible types: ArrayList cannot be converted to String

我想从表名中获取所有列

i want to get all columns from table name

   public String getListOfFiltersName(){

        ArrayList<String> arrTblNames = new ArrayList<String>();
        Cursor c = mydb.rawQuery("SELECT name FROM  " + MyDatabase.tableFilters, null);

        if (c.moveToFirst()) {
            while ( !c.isAfterLast() ) {
                arrTblNames.add( c.getString( c.getColumnIndex("name")) );
                c.moveToNext();
            }
        }
        c.close();
        mydb.close();
        return  arrTblNames;
    }
