How to send data from fragment to activity [duplicate]

Answer 1

You need to create an interface.

Like 

interface DataReciver
{

  void getData(String data);

}


public class MainActivity extends AppcompactActivity
{

 // On fragment load


oncreate
{
  DataReciver obj=new DataReciver()
  {
   @overide
   void getData(String data)
   {
      // Here is your data in data variable 

   }
  }


  frgamenttranstatiion.add(YOUR CONTAINER, new FRAGMENT1(obj));
}


}


Create a fragment with constructor

public class Fragment1
{


 Fragment1(DataReciver datareciver)
 {
   datareciver.getData("amit sharma");
 }
}
