title: How to call method in fragment from adapter Android
body: <p>I need help so I have a fragment which has a <code>RecycleView</code> and inside the <code>RecycleView</code> there is a button.</p>
  
  <p>The button after click must open the dialog which already declared in base fragment so I only call like <code>openDialog(DIALOG_CHECK);</code> </p>
  
  <p>Now how can I call that dialog on my adapter I already make a method in fragment and call it from the adapter and make an error "Java lang null pointer" </p>
  
  <p>This is my code : </p>
  
  <pre><code>DeliveryFragment delivFrag = new DeliveryFragment();
  holder.editButton.setOnClickListener(new View.OnClickListener() {
       @Override
       public void onClick(View v) {
           delivFrag.doEdit();
       }
  });
  </code></pre>
  
  <p>And in fragment </p>
  
  <pre><code>public void doEdit(){
     openDialog(DIALOG_EDIT_ITEM);
  }
  </code></pre>
