【问题描述】：

真的很烦。

当我在任何隔离活动或片段中使用 TintImageView 或 FloatingActionButton 时，它们都运行良好。

但是当我在 RecyclerView 中使用它们时，会出现以下异常： android.view.InflateException：

android.view.InflateException: Binary XML file line #79: Error inflating class "unknown"

这是完整版：

好的，我会发布我的源代码。

这是我的毕业作品：

RecyclerView Adapter 是这样的：

                          .inflate( R.layout.listitem_credit_list_mine, parent, false )
    );
    return holder;
}
@Override
protected void onBindViewHolderBase ( CreditViewHolder holder, int position ) {
    final Credit mCreditAtPosition = mList.get( position );

    holder.mTextView_Name.setText( mCreditAtPosition.getName() );
    holder.mTextView_Credit.setText( mCreditAtPosition.getCredit() );
    try {
        holder.mTextView_End.setText(

                        Credit.YYYY_MM_DD.parse( mCreditAtPosition.getDeadLineDate().getDate() )

        );
    }
    catch ( ParseException e ) {
        e.printStackTrace();
    }
    holder.mTextView_PostBy.setText(

    );
    holder.mTextView_UsedBy.setText(

    public CreditViewHolder ( View view ) {

错误日志指向这一行：

CreditViewHolder 持有人 = 新 CreditViewHolder( LayoutInflater.from(mContext) .inflate（R.layout.listitem_credit_list_mine，父母，假） );

我在 SOF 上尝试了一些类似的问题，但没有一个可以像这样解决我的问题。所以我希望有人能给我一个提示吗？非常感谢！

对不起，我的英语不好！

对不起，我忘了说我的设备操作系统是 Android 4.4.2 API19。

另外，片段中的代码

            break;
        case POSITION_1_USED:
        case POSITION_2_USEDBYME:
            mAdapter =
                    new CreditList_UsedAdapter( getActivity().getApplicationContext(), mList );
            break;
        case POSITION_3_POSTBYME:
            mAdapter =
                    new CreditList_MineAdapter( getActivity().getApplicationContext(), mList );
            break;
        case POSITION_4_OUTOFDATE:
            mAdapter = new CreditList_OutofDateAdapter(
                    getActivity().getApplicationContext(), mList
            );
            break;
        default:
            mAdapter =
                    new CreditList_FreshAdapter( getActivity().getApplicationContext(), mList );
            break;
    }
    mRecyclerView.setAdapter( mAdapter );
    mRecyclerView.setLayoutManager( new LinearLayoutManager( getActivity() ) );

BaseRecyclerAdapter 是这样的：

public abstract class BaseRecyclerAdapter < VH extends RecyclerView.ViewHolder, T >
    extends RecyclerView.Adapter< VH > {

protected Context mContext;
protected List< T > mList;
protected RecyclerViewOnItemClickLitener mRecyclerViewOnItemClickLitener;
public BaseRecyclerAdapter ( Context inContext, List< T > inList ) {
    this.mContext = inContext;
    this.mList = inList;
}
public T getItemAtPosition ( int inPosition ) {
    if ( mList != null ) {
        return mList.get( inPosition );
    }
    return null;
}
public void setRecyclerViewOnItemClickLitener (
        RecyclerViewOnItemClickLitener mRecyclerViewOnItemClickLitener
) {
    this.mRecyclerViewOnItemClickLitener = mRecyclerViewOnItemClickLitener;
}
@Override
public void onBindViewHolder ( final VH holder, int position ) {
    onBindViewHolderBase( holder, position );
    if ( mRecyclerViewOnItemClickLitener != null ) {
        holder.itemView.setOnClickListener(
                new View.OnClickListener() {

                    @Override
                    public void onClick ( View v ) {
                        if ( mRecyclerViewOnItemClickLitener != null )
                            mRecyclerViewOnItemClickLitener.onItemClick(
                                    holder.itemView, holder.getLayoutPosition()
                            );
                    }
                }
        );
        holder.itemView.setOnLongClickListener(
                new View.OnLongClickListener() {

                    @Override
                    public boolean onLongClick ( View v ) {
                        if ( mRecyclerViewOnItemClickLitener != null )
                            mRecyclerViewOnItemClickLitener.onItemLongClick(
                                    holder.itemView, holder.getLayoutPosition()
                            );
                        return false;
                    }
                }
        );
    }
}
protected abstract void onBindViewHolderBase ( VH holder, int position );

@Override
public int getItemCount () {
    return mList == null ? 0 : mList.size();
}

}

【问题讨论】：

在LayoutInflater.createView 中放置一个断点并调试您的代码，如此简单！
在初始化回收站视图的位置显示活动代码
@Android Weblineindia 活动代码已发布，如果我在 listitem 布局中删除 TintImageView，它将正常运行！

标签： android

【解决方案1】：

android:background="?attr/selectableItemBackground" 引起了几个充气问题，如果没有必要，只需将其删除并重试或者一起试试

android:clickable="true"
android:focusable="true"
android:background="?android:attr/selectableItemBackground"

【讨论】：

这不是问题，但它有很大帮助！在 XML 这一行引起了麻烦，当我删除它们时，问题就解决了。有点像你的回答，非常感谢！

【解决方案2】：

我认为您尚未初始化 mContext 变量。在 CreditList_MineAdapter() 构造函数中将其初始化为 mContext=context。试试这个。希望它可能会有所帮助。

【讨论】：

其实我是这样做的。我重构了一个名为“BaseRecyclerAdapter”的父适配器，并且在该类中我确实启动了受保护的字段 mContext。如您所见，此 CreditList_MineAdapter 扩展了 BaseRecyclerAdapter。
事实上我认为如果 mContext 没有被启动 "LayoutInflater.from( mContext )" 可能会抛出一些异常，比如空指针什么的。

【解决方案3】：

不适合我。

@Override
        public ViewHolders onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {
               View v = LayoutInflater.from(getApplicationContext()).inflate(R.layout.item, viewGroup, false);
               return new ViewHolders(v);
         }

为我工作

public ViewHolders onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {
       View v = LayoutInflater.from(MainActivity.this).inflate(R.layout.item, viewGroup, false);
       return new ViewHolders(v);
}

只需放置 MainActivity.this 而不是 getApplicationContext()
