Question

In my app I have a header with icon hidden, I have a adapter with a listview when I click the listview I go to a login screen using listener, when the login is successful is should come back to listview(adapter) and icon should get visible on header. i am sending intent as follows: http://pastebin.com/4SKnyjVX

below is onclick the login button

public void onClick(View v) {

    String password = etPassword.getText().toString();

    if(password.equals("guest")){
        Intent returnIntent = new Intent();
        returnIntent.putExtra("result",result);
        setResult(1,returnIntent);     
        finish();
    } else {
        //----
    }

    finish();                  
}

how can i use onActivityResult to set a flag and use this flag in click listener,
and also use it to make the icon visible. Any suggestion is appreciated

Answer 1

In your previous activity where you have listview with hidden icon in header, override the function onActivityResult() something like this –

protected void onActivityResult (int requestCode, int resultCode, Intent data) {
    boolean success = data.getBooleanExtra("result", false);
    if(success) {
        hiddenIcon.setVisibility(View.VISIBLE);
    }
    else {
        showDialog("Error");
   }
}

And I’ve changed your onClick this way

public void onClick(View v) {

        String password = etPassword.getText().toString();
        Intent returnIntent = new Intent();
        if(password.equals("guest")){
            returnIntent.putExtra("result", true);
            setResult(RESULT_OK, returnIntent);     
        } 
        else {
            returnIntent.putExtra("result", false);
            setResult(RESULT_OK, returnIntent);
        }

        finish();                  
    }
