我需要将样式和只读属性应用于drupal表单的输入元素.我编码如下:

$form['precio'] = array(
  '#type' => 'textfield',
  '#title' => t('Precio'),
  '#default_value' => ''.$precio,
  '#size' => 20,
  '#required' => TRUE,
  '#attributes' => array($inputAtributo => 1),
  '#description' => t('Modifica el precio '),
);

并在 '#attributes' => array($inputAtributo => 1),

在创建表单之前,我检查这个输入是否应该是readonly并应用一些样式:

if ($tarifa !='' & $tarifa=='N')
$inputAtributo=" readonly style=\"background: none repeat scroll 0 0 #EAEAEA;\" ";
else
$inputAtributo = "";

这有效,但我认为它编码不正确

html代码显示以下内容:

<input id="edit-precio" class="form-text required" type="text" maxlength="128" size="20" value="258" name="precio" ="1"="" style="background: none repeat scroll 0 0 #EAEAEA;" readonly="">

我怎么能做得更好？

在Android 4.2我的应用程序工作正常,但当我尝试使用Android 4.0.4测试它我有这个消息错误:
