[英]android.content.res.Resources$NotFoundException: Unable to find resource ID
In my RecyclerView I need replace part of my item to my fragment. 在我的RecyclerView中,我需要将部分物品替换为片段。 I have followed this answer by Victor Cruz and I am able to achieve what I wanted.
我遵循了维克多·克鲁兹(Victor Cruz)的回答,能够实现我想要的。
Everything is working fine but I am facing one serious problem ie I am getting Resources$NotFoundException Unable to find resource ID
only in the last item of my RecyclerView, note that this problem is occurring only in the last item rest others are working fine. 一切工作正常,但是我面临一个严重的问题,即我正在获取
Resources$NotFoundException Unable to find resource ID
仅在我的RecyclerView的最后一项中Resources$NotFoundException Unable to find resource ID
,请注意,此问题仅在最后一项中发生,其他情况都很好。
Steps which I have tried: 我尝试过的步骤:
I tried to look for the resource ID
in R.java file but all in vain. 我试图在R.java文件中查找
resource ID
,但徒劳无功。
I have tried reducing and increasing the number of items in RecyclerView but the problem is still the same. 我尝试减少和增加RecyclerView中的项目数量,但问题仍然相同。
Please give suggestions where am I doing wrong. 请提出建议,我在哪里做错了。 I will be happy to provide any other relevant details.
我很乐意提供其他相关细节。
After 5 days of posting the Question (and struggling with this for a week), I am not able to figure problem out. 发布问题5天后 (并为此苦苦了一周), 我无法解决问题。 I have made a small sample app performing this particular task, You can download the code from here.
我制作了一个小示例应用程序来执行此特定任务,您可以从此处下载代码。
Please help me out of this. 请帮助我。
Edit: Posting code: 编辑:邮政编码:
private void flipcard(final RecyclerView.ViewHolder holder)
{
final MyHolder myHolderflipcard= (MyHolder) holder;
// Delete old fragment
int containerId = myHolderflipcard.container.getId();// Get container id
Fragment oldFragment = ((FragmentActivity) context).getFragmentManager().findFragmentById(containerId);
if(oldFragment != null)
{
((FragmentActivity) context).getFragmentManager().beginTransaction().remove(oldFragment).commit();
}
int newContainerId = getUniqueId();
// Set the new Id to our know fragment container
myHolderflipcard.container.setId(newContainerId);
// Just for Testing we are going to create a new fragment according
// if the view position is pair one fragment type is created, if not
// a different one is used.
{
Fragment f;
f = new CardBackFragment();
// Then just replace the recycler view fragment as usually
((FragmentActivity) context).getFragmentManager().beginTransaction()
.setCustomAnimations(
R.animator.card_flip_right_in,
R.animator.card_flip_right_out,
R.animator.card_flip_left_in,
R.animator.card_flip_left_out)
.addToBackStack(null)
.replace(newContainerId, f).commit();
myHolderflipcard.cardView.setVisibility(View.GONE);
}
}
// Method that could us an unique id
private int getUniqueId(){
return (int)
SystemClock.currentThreadTimeMillis();
}

This problem is interesting. 这个问题很有趣。 After debugging your sample app for a while this is my finding:
在调试示例应用程序一段时间后,这是我的发现:
resource id
that is missing is the id of created fragment - CardBackFragment
. resource id
是创建的片段的ID- CardBackFragment
。 resource id
is given dynamically after you replace and commit the fragment resource id
For prof of what I have just said, here is a screenshot when I was debugging your app notice the id that is shown: 为了证明我刚才所说的,这里是我调试您的应用程序时的屏幕截图,请注意显示的ID :
And here is the missing id that the debugger told it was missing:
这是调试器告诉它丢失的丢失的ID:
And to be clear, the newContainerId
tis translated into hex id that is here (sorry for my bad english) 需要明确的是,
newContainerId
翻译为此处的十六进制ID (对不起,我的英语不好)
So what happen here? 那么这里发生了什么?
The answer lies in the way the code is execute the line: myHolderflipcard.cardView.setVisibility(View.GONE);
答案在于代码执行该行的方式:
myHolderflipcard.cardView.setVisibility(View.GONE);
That was trigger after you commit the fragment to be shown. 提交要显示的片段后,该触发器被触发。
Here is what happen: When you told the card view to be gone, the last item is removed from ui -> Because it is removed from ui and it is the last item on the recycler view -> the height of the recycler view
is shorten to minimize the view
. 这里是什么情况:当你告诉卡片视图中消失了,最后一个项目是从用户界面中删除- >因为它是从用户界面中删除,这是对回收视图中的最后一个项目- >的高度
recycler view
是缩短使view
最小化。 The bug happen for the last item because the recycler view
understand that the row layout
that hold the question is empty and it is the last item -> the last item is instead transfer to the question row above. 该错误发生在最后一个项目上,因为
recycler view
了解到容纳该问题的row layout
为空,并且它是最后一个项目->最后一个项目被转移到上面的问题行。 Meanwhile, the thread that insert the fragment
into your framelayout
is not done. 同时,未将
fragment
插入framelayout
的线程。 So when it's done and it try to find the containerid
, it cannot find it. 因此,当它完成并尝试找到
containerid
,它找不到它。 Hence, the crash. 因此,崩溃。
So the way to fix it is to wait for the frame to be added completely then you remove the question 因此,解决问题的方法是等待框架完全添加, 然后删除问题
Here is the fix: 解决方法是:
Remove myHolderflipcard.cardView.setVisibility(View.GONE);
删除
myHolderflipcard.cardView.setVisibility(View.GONE);
line from your flipcard
method 您的
flipcard
方法中的一行
On the outside create a: private MyHolder curHolder;
在外部创建一个:
private MyHolder curHolder;
Create a runnable to hide the CardView: 创建一个可运行的以隐藏CardView:
private Handler handler = new Handler(); private Runnable runnable = new Runnable() { @Override public void run() { Log.d("mId", String.valueOf(curHolder.container.getId())); curHolder.cardView.setVisibility(View.GONE);
// handler.postDelayed(this, 500); // handler.postDelayed(this,500); } };
};
post it after the commit is done: 提交完成后将其发布:
Fragment f; f = new CardBackFragment(); // Then just replace the recycler view fragment as usually ((FragmentActivity) context).getFragmentManager().beginTransaction() .setCustomAnimations( R.animator.card_flip_right_in, R.animator.card_flip_right_out, R.animator.card_flip_left_in, R.animator.card_flip_left_out) .addToBackStack(null) .replace(newContainerId, f).commit(); // Once all fragment replacement is done we can show the hidden container handler.post(runnable);
Although it happens really fast. 尽管它发生的非常快。 You can use
handler.postDelayed(runnable, 100);
您可以使用
handler.postDelayed(runnable, 100);
instead if you want to ensure that the fragment is successfully replaced under any circumstances 相反,如果您想确保在任何情况下都能成功替换该片段
And here is the full code (since I'm really bad at english, so I post it just in case) 这是完整的代码(因为我的英语真的很不好,所以我以防万一)
private void flipcard(final RecyclerView.ViewHolder holder)
{
final MyHolder myHolderflipcard= (MyHolder) holder;
String nim=mysr_id.get(Integer.parseInt(mpref.getradio_button_value()));
Pattern pattern = Pattern.compile("[0-9]+");
Matcher matcher = pattern.matcher(nim);
if (matcher.find())
{
currentsrid=Integer.parseInt(matcher.group(0));
if (currentsrid!=flag)
{
flag = Integer.parseInt(matcher.group(0));
// Delete old fragment
int containerId = myHolderflipcard.container.getId();// Get container id
Fragment oldFragment = ((FragmentActivity) context).getFragmentManager().findFragmentById(containerId);
if(oldFragment != null)
{
((FragmentActivity) context).getFragmentManager().beginTransaction().remove(oldFragment).commit();
}
int newContainerId = 0;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
newContainerId = View.generateViewId();
}
// Set the new Id to our know fragment container
myHolderflipcard.container.setId(newContainerId);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
curHolder = myHolderflipcard;
}
// Just for Testing we are going to create a new fragment according
// if the view position is pair one fragment type is created, if not
// a different one is used.
{
Fragment f;
f = new CardBackFragment();
// Then just replace the recycler view fragment as usually
((FragmentActivity) context).getFragmentManager().beginTransaction()
.setCustomAnimations(
R.animator.card_flip_right_in,
R.animator.card_flip_right_out,
R.animator.card_flip_left_in,
R.animator.card_flip_left_out)
.addToBackStack(null)
.replace(newContainerId, f).commit();
// Once all fragment replacement is done we can show the hidden container
handler.post(runnable);
//myHolderflipcard.container.setVisibility(View.VISIBLE);
//myHolderflipcard.radioGroup.setVisibility(View.GONE);
//myHolderflipcard.tvQuestion.setVisibility(View.GONE);
// myHolderflipcard.cardView.setVisibility(View.GONE);
}
}else
{
// backtoorignal=false;
// ((FragmentActivity)context). getFragmentManager().popBackStack();
}
}
}
private MyHolder curHolder;
private Handler handler = new Handler();
private Runnable runnable = new Runnable() {
@Override
public void run() {
Log.d("mId", String.valueOf(curHolder.container.getId()));
curHolder.cardView.setVisibility(View.GONE);
}
};
Just check small thing. 只是检查小东西。
It might not be the cause but normally it happens when setText on Textview with Integer(number). 它可能不是原因,但通常在具有Integer(number)的Textview上使用setText时会发生。
like bellow 像波纹管
int a = 999;
myTextView.setText(a);`
so I assume that you use setText call with number inside CardBackFragment 所以我假设您使用SetText调用CardBackFragment内的数字
