Why setText() of EditText is not working?

I want to put a string in a EditText in a AlertDialog,which is in a onItemClick Listener with a ListVIew.Here is the part of code 

dialogbuilder= new AlertDialog.Builder(this)

          .setTitle(R.string.title_connect_dialog)

          .setView(getLayoutInflater().inflate(R.layout.dialog_connect,null))

          .setPositiveButton("Connect", new DialogInterface.OnClickListener() {

              @Override

              public void onClick(DialogInterface dialog, int which) {
              }

          })

          .setNegativeButton("Cancel",new DialogInterface.OnClickListener() {

              @Override

              public void onClick(DialogInterface dialog, int which) {
              }

          })

          .create();



  LayoutInflater inflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);

  final View view = inflater.inflate(R.layout.dialog_connect, null);

 edit1 = (EditText)view.findViewById(R.id.devicename);

   edit2 = (EditText)view.findViewById(R.id.deviceadd);



private AdapterView.OnItemClickListener mDeviceClickListener = new AdapterView.OnItemClickListener() {



  public void onItemClick(AdapterView<?> adapterView, View v, int arg2, long arg3) {

        String info = ((TextView) v).getText().toString();

        name = info.substring(0,info.length() - 18);

        address = info.substring(info.length() - 17);

        dialogbuilder.show();

            edit1.setText(name);

            edit2.setText(address);

       }

};

When I run the project,there is nothing in the EditText!It does not work!But there is no exception or error.I tried only set text in the XML file can work.I replaced EditText with TextView ,but is not work too. Are there something wrong in logical?Thank you for reading.

Use as view instance for accessing Views form Dialog layout which you are passing in setView method of AlertDialog.Builder change:

  .setView(getLayoutInflater().inflate(R.layout.dialog_connect,null))

to

  .setView(view)

EDIT:

or instead of inflate layout again to access views you should use dialogbuilder instance to initialize EditText as:

edit1 = (EditText)dialogbuilder.findViewById(R.id.devicename);
edit2 = (EditText)dialogbuilder.findViewById(R.id.deviceadd);

You are showing the Dialog before setting the text

dialogbuilder.show();

edit1.setText(name);
edit2.setText(address);

Try changing that around

edit1.setText(name);
edit2.setText(address);
dialogbuilder.show();
