If you want to compare array values to string you can use for loop to check your array values one by one:

 String[] products= "Acer", "HP", "Lenova";
 for(String s : products)
 if(s.equals("HP"))
 startActivity(new Intent(this, hpcomputer.class));
 
 

Please note that you are using products.toString() on the entire array so it will look like this:

["Acer", "HP", "Lenova"]

Now, every time that you will use entireString.equal("just part of the string") method the result will return false because the entire string got more chars and it will never be equal to a part of it.

Edit - after seeing your last comment it would be a lot more simple to just check if your item that got clicked was "HP":

public void onItemClick(AdapterView<?> adapterView, View view, int position, long l) 
 String[] products= "Acer", "HP", "Lenova";
 if(position == 1)
 //"HP" got clicked
 else if(position == 2)
 //"Lenova" got clicked
 else
 //"Acer" got clicked
