Android的tabactivity - 如何改变选择标签图标图像 [英] Android tabactivity - how to change icon image on selecting a tab

问题描述

在我tabactivity，我显示图标，我从数据库中获取，通过创建一个ImageView的和passsing这给setIndicator方法。我只有一个图像的每个选项卡上，所以我想知道是否有办法只是改变单独图像的颜色（而不是改变标签的颜色）当选择一个标签？也有可能隐藏在选择一个选项卡正被在标签底部绘制的灰线？
任何帮助是AP preciated..thanks

In my tabactivity, I display icon that I get from the database, by creating an ImageView and passsing this to the setIndicator method. I have only one image for each tab, so I was wondering if there is way to just change the color of the image alone (as opposed to changing the tab's color) when a tab is selected? Also is it possible to hide the gray line that is being drawn at the bottom of the tabs when a tab is selected? Any help is appreciated..thanks

推荐答案

隐藏灰线：

yourTabWidget.setStripEnabled(false);

每个标签状态设置自定义图片：

Setting custom image per tab state:

tabitemicon.xml：

tabitemicon.xml:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- When selected, use grey -->
    <item android:drawable="@drawable/orange"
          android:state_selected="true" />
    <!-- When not selected, use white-->
    <item android:drawable="@drawable/white" />
</selector>

Java的code：

Java code:

tabHost = getTabHost():
tabHost.newTabSpec("test").setIndicator("My Tab Title",
                          res.getDrawable(R.drawable.tabitemicon))
                      .setContent(someIntent);
