使用ViewPager与ActionsContentView [英] Using ViewPager with ActionsContentView
本文介绍了使用ViewPager与ActionsContentView的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
所以我使用 ActionsContentView
我的目标是在它实施ViewPager元素。利用只是一个其他视图。有没有人在这个项目做到了这一点？作者说，它不容易做，看到我是如何还在Android的编程（iOS版从迁移）很新，我觉得我需要帮助。
我已经准备好ViewPager的文档，但也似乎不能让他们正确地连接起来。
和帮助将是AP preciated。

所以我设法获取其中的大部分用这个教程演示程序工作<一个href=\"http://looksok.word$p$pss.com/2013/10/26/android-support-v4-viewpager-tutorial-including-source-$c$c/\" rel=\"nofollow\">http://looksok.word$p$pss.com/2013/10/26/android-support-v4-viewpager-tutorial-including-source-$c$c/,然而，当我点击链接抽屉里，他们没有在主视图更新。
当它在RelativeLayout的设置，但ViewPager被打破这一部分将在下面的点击响应，但在设置的LinearLayout时，ViewPager工作，但不会链接响应。
＆LT; LinearLayout中的xmlns：机器人=http://schemas.android.com/apk/res/android
机器人：ID =@ + ID /内容
机器人：layout_width =FILL_PARENT
机器人：layout_height =FILL_PARENT
机器人：方向=垂直＆GT;＆LT; android.support.v4.view.ViewPager
机器人：ID =@ + ID / myViewPager
机器人：layout_width =FILL_PARENT
机器人：layout_height =FILL_PARENT/＆GT;
＆LT; / LinearLayout中＆GT;
另一件事我可能会想，在我的MainActivity，它没有更新正确的看法。点击它，关闭抽屉，然后什么也没有发生。我的继承人MainActivity。

解决方案
感谢您使用ActionsContentView库。
要在 ViewPager 更新片段的内容，请尝试更换 updateContent 方法体与下一个code：
公共无效updateContent（URI URI）{
如果（URI == NULL）
返回; 最后WebViewFragment webViewFragment =（WebViewFragment）
pageAdapter.getItem（MyPagerAdapter.WEBVIEW_FRAGMENT_POSITION）;
webViewFragment.setUrl（uri.toString（））;
webViewFragment.reload（）;
currentUri = URI;
}
我得到了Web视图后，为了将内容加载到 ViewPager 的主框架。
So I'm using ActionsContentView My goal is to implement a ViewPager element within it. Utilizing just one other view. Has anybody done this with this project? The author says it's not easily done, and seeing how I'm still very new in Android programming (migrated from iOS) I feel I need help.
I have ready the docs on ViewPager, but couldn't seem to make them link up properly.
And help would be appreciated.
UPDATE: 12/23
So I managed to get most of this working on the demo app using this tutorial http://looksok.wordpress.com/2013/10/26/android-support-v4-viewpager-tutorial-including-source-code/, however, when I click links in the drawer, they don't update in main view.
This one part below will respond to clicks when its set in RelativeLayout, but ViewPager is broken, but when set in Linearlayout, ViewPager works, but links wont respond.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/content"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<android.support.v4.view.ViewPager
android:id="@+id/myViewPager"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</LinearLayout>
Another thing I could be thinking that in my MainActivity, it's not updating the proper view. It clicks, closes the drawer and then nothing happens. Heres my MainActivity.

解决方案
Thanks for using ActionsContentView library.
To update content of fragment at ViewPager, please try replace updateContent method body with next code:
public void updateContent(Uri uri) {
if (uri == null)
return;
final WebViewFragment webViewFragment = (WebViewFragment)
pageAdapter.getItem(MyPagerAdapter.WEBVIEW_FRAGMENT_POSITION);
webViewFragment.setUrl(uri.toString());
webViewFragment.reload();
currentUri = uri;
}
I got web view to load content into main frame of ViewPager after that.
