i'm trying display data database 1 one changing if next button clicked. , wanted check if program select first data database error message.
caused by: android.database.sqlite.sqliteexception: no such column: color (code 1): , while compiling: select distinct _id, brand, model, price, color, img car _id=1 dbadapter.java

your problem here
private static final string database_create = "create table car (_id integer primary key autoincrement, " + "brand text, model text, price integer" // <-- no comma after 'integer'! + "color text, img blob);"; you missing comma. should be:
private static final string database_create = "create table car (_id integer primary key autoincrement, " + "brand text, model text, price integer," // <-- comma + "color text, img blob);";
