我现在用的是TabHost在我的应用程序，我使用的四个选项卡在我的应用程序，我想使用不同的图像在TabHost当特定选项卡中被选中，而不是选择。我需要使用不同的图像的每一个特定的标签。

I am using the TabHost in my application, I am using four Tabs in my application and I want to use the different Images in the TabHost when the Particular Tab is been Selected and not selected. I need to use to different Images for a particular tab each.

推荐答案

如果你想使用不同的图像选择和未选中状态，然后创建一个在您可绘制文件夹选择XML文件为每个标签，如： tab1_selector.xml，tab2_selector.xml应包含以下内容，更换绘制引用您的图片选择和未选中状态。即。

If you wish to use different images for the selected and unselected states, then create 'selector' XML files in your drawables folder for each tab, e.g. tab1_selector.xml, tab2_selector.xml which should contain the following, replacing the drawable references to your images for selected and unselected states. i.e.

    <?xml version="1.0" encoding="utf-8"?>
<selector
  xmlns:android="http://schemas.android.com/apk/res/android">
  <item
    android:state_selected="true"
    android:drawable="@drawable/tab1_selected_image" />
  <item
    android:state_selected="false"
    android:drawable="@drawable/tab2_unselected_image" />
</selector>

然后用.setIndicator方法bharath上面写的是要参考你的新的XML绘制资源。

Then using the .setIndicator method as bharath wrote above you should reference your new xml drawable resource.
