Question

How to intent from Fragment Activity Class going to a Fragment Class ?

the code below that i posted was used in an activity class where in there is a back button on the title bar.

now what i want to do is the same but i want to implement it in an fragment class

I tried this in my Activity Class..

   ActionBar actionBar = getActionBar();
    actionBar.setDisplayHomeAsUpEnabled(true);

and also

public boolean onOptionsItemSelected(MenuItem item){
    Intent myIntent = new Intent(getApplicationContext(), LoginActivity.class);
    startActivityForResult(myIntent, 0);
    finish();
    return true;

}

Answer 1

Try this

@Override
    public boolean onOptionsItemSelected(MenuItem item)
    {

        super.onOptionsItemSelected(item);
        int id = item.getItemId();

        switch(id)
        {

        case android.R.id.home:
            // if (page == PAGE_CHILD) finish();
        Intent myIntent = new Intent(getApplicationContext(), LoginActivity.class);
        startActivityForResult(myIntent, 0);
        finish();
            break;

        default:
            break;
        }
        return true;
    }

For fragments u can use

FragmentManager fragmentManager = getSupportFragmentManager();
        fragmentManager.popBackStack();

at the place of Intent.

Or replace the fragments

        LoginScreen firstFragment = new LoginScreen();

        FragmentManager fragmentManager = getSupportFragmentManager();
        FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
        fragmentTransaction.replace(R.id.article_fragment, firstFragment).commit();
