Android: SQLite update Single value in a col. and then all other of the same col

I have the below table in my DB

id         name         is_current

1          apple           0
2          banana          1
3          mango           0
4          grapes          1
5          pineapple       1

I want to execute an update query which will update the (fruit) table last column (is_current) single value and at the same time the whole column values as well. For example the first row has an apple with id=1 and I want to set this value to 1 and all other fruit values to zero so the table look like,

id         name         is_current

1          apple           1
2          banana          0
3          mango           0
4          grapes          0
5          pineapple       0

Currently I am using two different queries and to different methods to achieve this

1st: is to set all values of is_current column to 0

String sql = "UPDATE "+TABLE_NAME +" SET " + is_current + " = '"+ Zero +"';

2nd: is to set the apple values to 1 by using id

String sql = "UPDATE "+TABLE_NAME +" SET " + is_current + " = '"+ One +"' WHERE "+ id + " = "+rowId;

So how can I combine these two queries to a single one to achieve this?
