Refresh Activity

This is my scenario

Desired Flow in app

Step 1: A ==> B

Step 2: B ==> A

Step 3 (Required flow):

Activity A has to reload itself or call loadListView() function after Activity B exits or is closed.

onCreate(){
.......
....
        btnAddClient.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent( ActivityA.this, ActivityB.class);
                startActivity(intent);
            }
        });

        loadListView();
......
....
}

Getting a result from an activity

From your Activity A, call the Activity B using the startActivityForResult() method.

int RESULT_CODE = 123;
Intent intent = new Intent(this, ActivityB.class);
startActivityForResult(intent, RESULT_CODE);

Now in your ActivityA class, write the following code for the onActivityResult() method.

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == RESULT_CODE) {
        if(resultCode == Activity.RESULT_OK){
            bool status=data.getBooleanExtra("isUserAdded");
            if(status)
            {
             loadListView();
            }
        }
    }
} //onActivityResult

Return back to ActivityA with status.

Intent returnIntent = new Intent();
returnIntent.putExtra("isUserAdded",true);
setResult(Activity.RESULT_OK,returnIntent);
finish();

Try to call loadListView() in onStart or onResume methods. It will refresh the list when you come back to your activity
