SQLite 主键自增长，插入后返回ID信息

SQLiteDatabase db = helper.getWritableDatabase();
db.execSQL("insert into person(name,phone,amount) values(?,?,?) ", new Object[]{person.getName(), person.getPhone(), person.getAmount()});
Cursor cursor = db.rawQuery("select last_insert_rowid() from person", null);
int strid;
if (cursor.moveToFirst()) strid = cursor.getInt(0);
Log.i("testAuto", strid + "");
