title: If statements and AlertDialog boxes
body: <p>I have this application which when you logged in, you will see a list of things like names. I have an Add, Update, and Delete button as well. When I hit the edit button, it will go to the edit page and and you can edit a name there. Now, when you hit the Update button, I have an AlertDialog which will ask for the user's username and password again. Here is the code I made:</p>
  
  <pre><code>public void btn_add_update_click(View v){
      hideKeyboard();
      final String username = getIntent().getStringExtra("USERNAME");
      final String str_sitename = this.edt_sitename.getText().toString();
      String str_username = this.edt_username.getText().toString();
      String str_password = this.edt_password.getText().toString();
      LayoutInflater li = LayoutInflater.from(context);
      View prompt = li.inflate(R.layout.prompts, null);
      AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(context);
      alertDialogBuilder.setView(prompt);
      final EditText user = (EditText) prompt.findViewById(R.id.loginEmail);
      final EditText pass = (EditText) prompt.findViewById(R.id.loginPassword);
      final TextView msg = (TextView) prompt.findViewById(R.id.login_error);
      final String password = pass.getText().toString();
      user.setText(getIntent().getStringExtra("USERNAME"));
  
  
      if (str_sitename.equals("")){
          //edt_sitename.requestFocus();
          show_mesg("Please insert sitename.");
      }else if (str_username.equals("")){
          //edt_username.requestFocus();
          show_mesg("Please insert username.");
      }else if (str_password.equals("")){
          //edt_password.requestFocus();
          show_mesg("Please insert password.");
      }else{
          if (selected_website!=null){
              selected_website.setUser(username);
              selected_website.setSitename(str_sitename);
              selected_website.setUsername(str_username);
              selected_website.setPassword(str_password);
                  alertDialogBuilder.setCancelable(false)
                  .setPositiveButton("OK", new DialogInterface.OnClickListener() {
                      @Override
                      public void onClick(DialogInterface dialog, int which) {    
                          DBAdapter dbUser = new DBAdapter(PasswordActivity.this);
                          dbUser.open();
                          if(dbUser.Login(username, password))
                          {
                                  datasource.updateWebsite(selected_website);
                                  show_mesg(str_sitename + " updated.");
                                  hideKeyboard();
                                  selected_website = null;
                                  show_list_layout(); 
                              }
                          else{
                              msg.setText("Username or Password is not correct.");
                              }
                          }
                  })
                  .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
                      @Override
                      public void onClick(DialogInterface dialog, int which) {
                          dialog.cancel();
  
                      }
                  });
                  AlertDialog alertDialog = alertDialogBuilder.create();
                  alertDialog.show(); 
          }
  
          else{
              datasource.addWebsite(username, str_sitename,str_username,str_password);
              hideKeyboard();
              show_mesg(str_sitename + " added.");
              selected_website = null;
              show_add_layout();
          }
      }
  }
  </code></pre>
  
  <p>But when I run it, it doesn't work. The OK and the Cancel button is not showing up.
  Any advice on this?</p>
