public void LoginDialog(final Context context){
  AlertDialog.Builder builder = new AlertDialog.Builder(context);
  LayoutInflater inflaterDl = LayoutInflater.from(this);
   LinearLayout layout = (LinearLayout)inflaterDl.inflate(R.layout.logindialog, null );

  final EditText userNameET = (EditText)layout.findViewById(R.id.username);
  final EditText passwordET = (EditText)layout.findViewById(R.id.password);
  
  builder.setTitle(“登录”).setPositiveButton(确定“”), new DialogInterface.OnClickListener() {
   
   @Override
   public void onClick(DialogInterface dialog, int which) {
    // TODO Auto-generated method stub
   String  username = userNameET.getText().toString();
   String password = passwordET.getText().toString();
       }
  }).setNegativeButton("取消"), new DialogInterface.OnClickListener() {
   
   @Override
   public void onClick(DialogInterface dialog, int which) {
    // TODO Auto-generated method stub
    
   }
  });
  builder.setView(layout);
  AlertDialog ad = builder.create();
  ad.show();
 }
