You can make it simpler by the use of string's split function.

Follow these steps:

1)Make a large string of timeslots separated by unique character

2)Pass the string to another activity

3)Fetch the string and split it into array

First Activity

Java

SQLiteDatabase db = openOrCreateDatabase("MyDB",MODE_PRIVATE, null);
Cursor c=db.rawQuery("SELECT timeslots FROM medprofile",null);
	    
	    
String timeslots="";
int i=0;
while(c.moveToNext())
	{
		 String uname = c.getString(c.getColumnIndex("timeslots"));
			    timeslots+=uname+"#";
		  Toast.makeText(getApplicationContext(), uname, Toast.LENGTH_SHORT).show();
	 }	
 
	Intent in=new Intent(MainActivity.this,profileview.class);
		
	 in.putExtra("timeslots",timeslots);
	 startActivity(in);
			
}

Second Activity

Add this code in onCreate method of second activity

Java

 Bundle extras=getIntent().getExtras();
String[] timeslots=extras.getString("timeslots").split("#");
