action_bar_embed_tabs如何在Android中正常运行？

Question

我在操作栏中有标签.在大屏幕上,标签嵌入到操作栏中,但在小屏幕上则没有.我想控制选项卡手册,以便我可以将选项卡与操作栏分开.我试图设置abs__action_bar_embed_tabs,但这不起作用

<resources>
    <bool name="abs__action_bar_embed_tabs">false</bool>
</resources>

我知道这是一篇旧帖子,但我想action_bar_embed_tabs为未来的读者添加一个解决方案.

创建以下方法(注意导入),

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) {}
}

然后像下面这样调用,

1. 如果您希望选项卡显示在操作栏内,

   setHasEmbeddedTabs(actionBar, true);

2. 如果您希望标签显示在操作栏的下方/下方,

   setHasEmbeddedTabs(actionBar, false);

所有积分给克里夫.

我找到了一个解决方案来分隔代码中的选项卡.

private void embeddedTabs(Object actionBar, Boolean embed_tabs) {
    try {
        if (actionBar instanceof ActionBarWrapper) {
            // ICS and forward
            try {
                Field actionBarField = actionBar.getClass()
                        .getDeclaredField("mActionBar");
                actionBarField.setAccessible(true);
                actionBar = actionBarField.get(actionBar);
            } catch (Exception e) {
                Log.e("", "Error enabling embedded tabs", e);
            }
        }
        Method setHasEmbeddedTabsMethod = actionBar.getClass()
                .getDeclaredMethod("setHasEmbeddedTabs", boolean.class);
        setHasEmbeddedTabsMethod.setAccessible(true);
        setHasEmbeddedTabsMethod.invoke(actionBar, embed_tabs);
    } catch (Exception e) {
        Log.e("", "Error marking actionbar embedded", e);
    }
}

但现在我遇到了一个新问题.标签不会完全填充标签栏. 操作栏选项卡未填充选项卡栏
