android.content.res.Resources $ NotFoundException：无法找到资源编号为0xffffffff编号、资源、res、content
我讨厌张贴code，并问为什么它不工作，但我无所适从现在。我试着运行下面的下面的类，而我得到了logcat的异常，我无法解释。即使谷歌搜索产生很少的结果。也许我只是不明白的生态系统，但除有少量信息。我得到的例外如下：
I hate posting code, and asking why it doesn't work, but I'm at a loss right now. I've tried to run the following class below, and I get an exception in logcat which I can't explain. Even a google search yields little results. Maybe I just don't understand the ecosystem, but the exception has little information. The exception I'm getting is below:

我试图移动ViewPager顶端级别的内容（即setContent（寻呼机）），但似乎并没有工作。任何投入是值得欢迎的。在code是如下：
I tried moving the ViewPager to the top level content (i.e. setContent( pager )) but that didn't seem to work. Any input is welcomed. The code is below:
修改* 我简化了的例子，我仍然得到了同样的问题。
EDIT* I Simplified the example, and I still get the same problem.
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;
import android.view.Gravity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.ViewGroup.LayoutParams;
import android.widget.LinearLayout;
import android.widget.TextView;
public class AskQuestionActivity extends FragmentActivity
{
private static LayoutParams MATCH_PARENT = new LayoutParams( LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT );
@Override
protected void onCreate( Bundle savedInstanceState )
{
super.onCreate( savedInstanceState );
ViewPager pager = new ViewPager( this );
pager.setAdapter( new FragmentPagerAdapter( getSupportFragmentManager() )
{
@Override
public int getCount()
{
return 1;
}
@Override
public Fragment getItem( int arg0 )
{
return new BoardFragment();
}
} );
setContentView( pager );
}
public static class BoardFragment extends Fragment
{
@Override
public View onCreateView( LayoutInflater inflater,
ViewGroup container,
Bundle savedInstanceState )
{
TextView textView = new TextView( getActivity() );
textView.setText( "Board" );
textView.setGravity( Gravity.CENTER );
LinearLayout layout = new LinearLayout( getActivity() );
layout.setLayoutParams( MATCH_PARENT );
layout.addView( textView );
return layout;
}
}
}
任何帮助是值得欢迎的。
Any help is welcomed.
推荐答案
所以，我会发布什么，我认为是解决我的问题。在添加一行到我上面code给 ViewPager 随机的ID;它成功地解决我的问题。
So I'll post what I think is the solution to my problem. After adding a single line to my above code giving the ViewPager a "random" ID; it managed to fix my problem.
起初，我确信，设定自己的ID是不好的做法，但显然也有这样做的合法途径。即通过创建一个 ids.xml 文件，并让Android生态系统产生一个ID为您服务。我建议检查出更多的信息，这些所谓的帖子 - here和here.
At first I was convinced that setting your own ID is bad practice, but apparently there are legitimate ways of doing this. Namely by creating an ids.xml file and letting the Android ecosystem generate an ID for you. I recommend checking out these SO posts for more information - here and here.
否则，我会建议只是创造您的布局XML文件，并获得 ViewPager 在活动（而不是编程实例化），但最终这一切都取决于你要完成的任务。
Otherwise, I would recommend just creating an XML file for your layout and getting the ViewPager in your Activity (instead of programmatically instantiating it), but ultimately it all depends on what you're trying to accomplish.
