如何action_bar_embed_tabs正是在Android的工作? [英] How does action_bar_embed_tabs exactly work in Android?
问题描述
我有卡在动作条。 在大屏幕上的选项卡嵌入到动作条,但在小屏幕上都没有。 我想控制标签说明书这样我就可以从动作条分开的选项卡。 我试图设置abs__action_bar_embed_tabs,但没有奏效。

<布尔名=abs__action_bar_embed_tabs>假< /布尔>
< /资源>
我知道这是旧的文章,但我想补充的使用为将来的解决方案 action_bar_embed_tabs
读者。
创建下面的方法(也照顾的进口),
公共静态无效setHasEmbeddedTabs(对象inActionBar,最后布尔inHasEmbeddedTabs)
{
//获取动作条类
类<> actionBarClass = inActionBar.getClass();
//如果它是一个果冻豆实现(ActionBarImplJB),得到了超类(ActionBarImplICS)
如果(android.support.v7.app.ActionBarImplJB.equals(actionBarClass.getName()))
{
actionBarClass = actionBarClass.getSuperclass();
}
尝试
{
//尝试获得mActionBar领域,由于当前动作可能只是一个包装类
//如果失败,不用担心,这将是本机动作条类或从ActionBarImplBase类的一个实例
最后一个字段actionBarField = actionBarClass.getDeclaredField(mActionBar);
actionBarField.setAccessible(真正的);
inActionBar = actionBarField.get(inActionBar);
actionBarClass = inActionBar.getClass();
}
赶上(IllegalAccessException E){}
赶上(抛出:IllegalArgumentException E){}
赶上(NoSuchFieldException E){}
尝试
{
//现在调用该方法setHasEmbeddedTabs,这将会把标签的动作条内
//如果失败,你在你自己的< IMG SRC =http://www.blogc.at/wp-includes/images/smilies/icon_wink.gifALT =;-)级= WP-笑脸>
最后一个方法方法= actionBarClass.getDeclaredMethod(setHasEmbeddedTabs,新的等级[] {Boolean.TYPE});
method.setAccessible(真正的);
method.invoke(inActionBar,新的对象[] {inHasEmbeddedTabs});
}
赶上(NoSuchMethodException E){}
赶上(的InvocationTargetException E){}
赶上(IllegalAccessException E){}
赶上(抛出:IllegalArgumentException E){}
}
然后把这个像下面,
-
如果您希望标签显示在操作栏里面,
setHasEmbeddedTabs(动作条,真);
-
如果您希望标签出现独立/下面的操作栏,
setHasEmbeddedTabs(动作条,假);
所有学分的悬崖。
I have tabs in an actionbar. On large screens the tabs are embed to the actionbar but on small screens the are not. I want to control the tabs manual so i can separate the tabs from the actionbar. I tried to set abs__action_bar_embed_tabs but that didn't work
<resources>
<bool name="abs__action_bar_embed_tabs">false</bool>
</resources>
I know this is an old post, however I would like to add a solution using action_bar_embed_tabs
for future readers.
Create the below method (do take care of the imports),
public static void setHasEmbeddedTabs(Object inActionBar, final boolean inHasEmbeddedTabs)
{
// get the ActionBar class
Class<?> actionBarClass = inActionBar.getClass();
// if it is a Jelly Bean implementation (ActionBarImplJB), get the super class (ActionBarImplICS)
if ("android.support.v7.app.ActionBarImplJB".equals(actionBarClass.getName()))
{
actionBarClass = actionBarClass.getSuperclass();
}
try
{
// try to get the mActionBar field, because the current ActionBar is probably just a wrapper Class
// if this fails, no worries, this will be an instance of the native ActionBar class or from the ActionBarImplBase class
final Field actionBarField = actionBarClass.getDeclaredField("mActionBar");
actionBarField.setAccessible(true);
inActionBar = actionBarField.get(inActionBar);
actionBarClass = inActionBar.getClass();
}
catch (IllegalAccessException e) {}
catch (IllegalArgumentException e) {}
catch (NoSuchFieldException e) {}
try
{
// now call the method setHasEmbeddedTabs, this will put the tabs inside the ActionBar
// if this fails, you're on you own <img src="http://www.blogc.at/wp-includes/images/smilies/icon_wink.gif" alt=";-)" class="wp-smiley">
final Method method = actionBarClass.getDeclaredMethod("setHasEmbeddedTabs", new Class[] { Boolean.TYPE });
method.setAccessible(true);
method.invoke(inActionBar, new Object[]{ inHasEmbeddedTabs });
}
catch (NoSuchMethodException e) {}
catch (InvocationTargetException e) {}
catch (IllegalAccessException e) {}
catch (IllegalArgumentException e) {}
}
Then call this like below,
If you want tabs to appear inside the action bar,
setHasEmbeddedTabs(actionBar, true);
If you want tabs to appear separate/ below the action bar,
setHasEmbeddedTabs(actionBar, false);
