Android 获得类似这样的选项卡式布局（在活动活动上加下划线）

android android-layout

Android 获得类似这样的选项卡式布局（在活动活动上加下划线）,android,android-layout,Android,Android Layout,我首先向您展示我想要获得的布局：有两个部分，活动部分用1dp线加上红色下划线：如果用户切换到第2部分，则第2部分加下划线，而第1部分不再加下划线。请注意，我不希望在选项卡式活动中使用图标，布局必须与图片中的一样：只需下划线文本。此外，另一条黑色1dp线将顶部导航栏与底层内容隔开。你能帮我吗？我不一定需要一个选项卡式的活动，即使只是线性布局和形状的组合也是可以的这是android sdk20附带的。有两种可能的类型，带或不带滑动手势（从一个选项卡转到另一个选项卡）不刷卡：

我首先向您展示我想要获得的布局：

有两个部分，活动部分用1dp线加上红色下划线：如果用户切换到第2部分，则第2部分加下划线，而第1部分不再加下划线。 请注意，我不希望在选项卡式活动中使用图标，布局必须与图片中的一样：只需下划线文本。

此外，另一条黑色1dp线将顶部导航栏与底层内容隔开。

你能帮我吗？我不一定需要一个选项卡式的活动，即使只是线性布局和形状的组合也是可以的

这是android sdk20附带的。有两种可能的类型，带或不带滑动手势（从一个选项卡转到另一个选项卡）

到

然后：

-删除所有导入并重新导入内容，当您有选择时，请始终选择“support.v4.”选项或“com.actionbarsherlock.app.”选项

-getActionBar（）到getSupportActionBar（）的所有发生

-getMenuInflater（）到getSupportMenuInflater（）的所有发生

有一个DummySectionFragment类，这只是一个片段的示例，您必须构建自己的片段，并更改活动类内的调用以匹配片段的名称

编辑：我忘了将您必须创建的xml粘贴到layout文件夹中（在res中）

不带滑动手势的选项卡： tabs.xml
