  1. Create Table table_name (_ id integer primary key autoincrement, Name text );

Save data:

[HTML]
View plaincopyprint?
  1. Contentvalues CV = new contentvalues ();
  2. Cv. Put ("_ id", null); // This sentence is optional.
  3. Cv. Put ("name", "Jack ");
  4. This. getwritabledatabase (). insert ("tabl_ename", null, CV );
