Removing fragment after adding does not work

My problem is that I want to remove Fragment

from Activity. There are two steps:

• Add Fragment
  
  to FrameLayout
  
  (R.id.frame_for_des_details) checking CheckBox
  
  .

• Delete Fragment
  
  by pushingTextView
  
  

  public class CreateTripActivity extends FragmentActivity {
  
  //Vars for Destination Fragment
  private CheckBox checkBox;
  private DestinationDetailsFragment destinationDetailsFragment;
  
  @Override
  protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  
  //Setting the ContentView
  setContentView(R.layout.activity_create_trip);
  
  //Set the Destination Checkbox listener
  checkBox = (CheckBox) this.findViewById(R.id.checkBox_destination_now);
  
        
  
          
          
          
        
  
      

Listener for CheckBox

:

    checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

        @Override
        public void onCheckedChanged(CompoundButton compoundButton, boolean b) {

            //Adding the Fragment. THIS WORK
            destinationDetailsFragment = new DestinationDetailsFragment();
            FragmentManager fm = getFragmentManager();
            fm.beginTransaction().add(R.id.frame_for_des_details, destinationDetailsFragment).commit();

        }
    });

      

        
        
        
      

    

Listener for TextView

:

    findViewById(R.id.label_later).setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            //Removing the Fragment. DOES NOT WORK
            FragmentManager fm = getFragmentManager();
            fm.beginTransaction().remove(destinationDetailsFragment).commit();              
        }
    });

    }

      

        
        
        
      

    

When I check CheckBox

, I can see the Fragment. But when I click TextView

to delete it, it remains. When I check over and over again CheckBox

, it seems like the new Fragment

overlays the old snippet, so I can write on top of the placeholders in EditText

.

Hope someone can understand me and can help me.

Thank.
