没有查看发现ID时，方向更改抛出：IllegalArgumentException：？ [英] No View found for id when orientation changes IllegalArgumentException:?
问题描述
我创建的应用程序。我有两种看法。
I am creating an application. I have two kinds of view.
ThumbView和放大器;网格视图。对于这些观点，我使用两种不同的FragmentStatePagerAdapters为ViewPager。随着主要布局，我创建了一个空间，以重用子视图基础上，选择要加载ThumbView或GridView的。
ThumbView & GridView. For these views I am using two different FragmentStatePagerAdapters for ViewPager. With in the main layout, I have created a space to reuse that subview to load ThumbView or GridView based on the selection.
public void loadThumbView()
{
LinearLayout subLayout= (LinearLayout)findViewById(R.id.subLayout);
subLayout.removeAllViews();
View subView =(View)inflater.inflate(R.layout.thumb_layout, null);
thumbViewPager=(ViewPager)subView.findViewById(R.id.pager);
thumbViewPagerAdapter=new ViewPagerAdapter(getSupportFragmentManager());
thumbViewPager.setAdapter(thumbViewPagerAdapter);
subLayout.addView(subView);
}
public void loadGridView()
{
LinearLayout subLayout= (LinearLayout)findViewById(R.id.subLayout);
subLayout.removeAllViews();
View subView=(View)inflater.inflate(R.layout.grid_layout, null);
test= new TestAdapter(getSupportFragmentManager(),this);
viewPager =(ViewPager)subView.findViewById(R.id.pager);
viewPager.setAdapter(test);
pageIndicator = (CirclePageIndicator)subView.findViewById(R.id.indicator);
pageIndicator.setViewPager(viewPager,0);
pageIndicator.setSnap(false);
subLayout.addView(subView);
}
这是我在做什么加载在MainLayout.xml一个subLayout
This is what I am doing to load view inside a subLayout in MainLayout.xml
但是，当我改变了方向，那么应用程序是越来越坠毁，因为在第2行中的上述code，我删除所有意见。当我转动我的应用程序，然后我的应用程序是越来越崩溃并出现以下错误。
But, when I change the orientation, then app is getting crashed because, at line 2 in the above code, I am removing all Views. When I rotate my app, then my app is getting crashed with the following error.

亚片段是一个扩展片段的类的名称。 如何处理呢？ 如何有力地摧毁/分离的片段？ 如何彻底删除ViewPager和放大器;对于一些行动的所有其相关的片段？
SubFragment is the name of the class that Extends Fragment. How to handle this? How to forcefully destroy/ detach fragments? How to completely remove ViewPager & all its associated Fragments for some action?
推荐答案
您可以覆盖 onConfigurationChanged（...）处理方向改变。
You can override onConfigurationChanged(...) to handle orientation changes.
将此行添加到您的＆LT;活性GT; 在mainfest：
Add this line to your <activity > in your mainfest:
android:configChanges="orientation"
添加此方法做你想要当方向改变什么
Add this method to do what you want when the orientation is changed
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
// Checks the orientation of the screen
if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
Toast.makeText(this, "landscape", Toast.LENGTH_SHORT).show();
} else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT){
Toast.makeText(this, "portrait", Toast.LENGTH_SHORT).show();
}
}
