我使用JSF 2,primefaces 4.0,我尝试使用DataTable – In-Cell Editing,因为它是在primefaces展示中生成的,但我有一个错误,虽然我复制了showcase中显示的相同示例
错误是

    //// Getters and setters
你嵌套了< p：ajax>在< p：column>内< p：ajax>需要嵌套在实现 ClientBehaviorHolder interface的组件中.但是,Column component class后面的< p：column>没有实现它. DataTable component class落后< p：dataTable>实现它.

你应该嵌套< p：ajax>在< p：dataTable>内代替：

<p:dataTable ...>
   <p:ajax ... /> 

   <p:column ...>
       ...
   </p:column>
</p:dataTable>

Exactly as demonstrated on their showcase site.换句话说,你的陈述

其实不是真的.

Android BottomSheetBehavior RecyclerView 滑动冲突解决

Android BottomSheetBehavior RecyclerView 滑动冲突解决

RecyclerView 在一个设置 BottomSheetBehavior 的 LinearLayout 中，BottomSheet 弹起时 RecyclerView 无法滑动，通过重写 Touch 监听由 RV 的不同状态进行事件消费处理滑动冲突

 recyclerView.apply {
            val linearLayoutManager = LinearLayoutManager(requireContext())
            layoutManager = linearLayoutManager
            adapter = rvAdapter
            var touched = false
            setOnTouchListener(View.OnTouchListener { v, event ->
                if(linearLayoutManager.findFirstCompletelyVisibleItemPosition()==0 && touched){
                    //RV到顶部item完全显示时将滑动交给父控件
                    v.parent.requestDisallowInterceptTouchEvent(false)
                    touched = false
                    return@OnTouchListener true
                }
                when (event.action) {
                    MotionEvent.ACTION_DOWN -> {
                        //不允许父控件拦截触摸事件
                        v.parent.requestDisallowInterceptTouchEvent(true)
                    }
                    MotionEvent.ACTION_UP -> {
                        //允许父控件拦截触摸事件
                        v.parent.requestDisallowInterceptTouchEvent(false)
                        touched = true
                    }

                }
                v.performClick()
                v.onTouchEvent(event)
                true
            })
        }

 

android studio：无法解析HttpClientBuilder

android studio：无法解析HttpClientBuilder

我在 Android工作室面临一个奇怪的问题.
我正在使用apache库来进行一些http请求,我需要更改 
org.apache.http.impl.client.DefaultHttpClient;

不赞成使用

org.apache.http.impl.client.HttpClientBuilder;

但android工作室没有找到那个包.
我能怎么做？

解决方法

添加到build.gradle和sync 
compile group: 'org.apache.httpcomponents',name: 'httpclient-android',version: '4.3.5'

android – BottomSheetBehavior有两个RecyclerView

android – BottomSheetBehavior有两个RecyclerView

我在LinearLayout中有一个带有BottomSheetBehavior的两个RecyclerView.当您单击第一个RecyclerView内的项目(带网格)时,RecyclerView将设置为Gone,并显示第二个RecyclerView(带有列表).当显示第二个Recycler时,您无法上下滑动BottomSheet而不是List即使在Expanded State中也在滚动.如果First Recycler已经上市,一切都很好.有没有办法让BottomSheet再次上下滑动？

<LinearLayout
        android:id="@+id/sliding_layout_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:focusable="true"
        android:focusableInTouchMode="true"
        android:orientation="vertical"
        app:behavior_hideable="false"
        app:behavior_peekHeight="400dp"
        app:layout_behavior="@string/bottomSheetBehavior">

        <android.support.v7.widget.RecyclerView 
           android:id="@+id/grid"
           android:layout_width="match_parent"
           android:layout_height="match_parent"
           android:layout_marginEnd="@dimen/activity_horizontal_margin"
           android:layout_marginStart="@dimen/activity_horizontal_margin"
           android:background="@color/white"
           android:clickable="true"
           android:scrollbars="none" />

        <android.support.v7.widget.RecyclerView 
           android:id="@+id/list"
           android:layout_width="match_parent"
           android:layout_height="match_parent"
           android:layout_marginEnd="@dimen/activity_horizontal_margin"
           android:layout_marginStart="@dimen/activity_horizontal_margin"
           android:background="@color/white"
           android:clickable="true"
           android:scrollbars="none" />
</LinearLayout>

GridAdapter：

   @Override
   public void onBindViewHolder(ViewHolder holder, int position) {

    String categorieName = mCategories.get(position);
    final CategoryFilterEvent event = new   CategoryFilterEvent(categorieName);
    holder.grid_item_label.setText(categorieName);

    holder.itemView.setonClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            EventBus.getDefault().post(event);
        }
    });
}

主要活动：

 @Override
 public void onCreate(Bundle savedInstanceState) {

    linearlayoutmanager = new linearlayoutmanager(this);
    listadapter = new listadapter(this, mList);
    recyList.setAdapter(listadapter);
    recyList.setLayoutManager(linearlayoutmanager);

    gridLayoutManager = new GridLayoutManager(this, 3);
    gridAdapter = new GridAdapter(this, new ArrayList<String>());
    recyGrid.setAdapter(gridAdapter);
    recyGrid.setLayoutManager(gridLayoutManager);
}

public void onEventMainThread(CategoryFilterEvent event) {
    recyGrid.setVisibilty(GONE);
    recyList.setVisiblity(VISIBLE);
}

解决方法:

BottomSheetBehavior的实现不支持内部的两个可滚动视图,这就是为什么这种布局永远不会“开箱即用”的原因.但是,这个问题有一个hacky但很简单的解决方法.首先,我们必须通过将该类的代码复制到我们的新CustomBottomSheetBehavior类来自定义BottomSheetBehavior.然后,通过替换行来修改“onLayoutChild”方法

mnestedScrollingChildRef = new WeakReference<>(findScrollingChild(child));

同

if (mnestedScrollingChildRef == null) {
    mnestedScrollingChildRef = new WeakReference<>(findScrollingChild(child));
}

mnestedScrollingChildRef在BottomSheetBehavior类中具有包级访问权限,因此我们无法扩展它.

比,添加以下方法：

public void setnestedScrollingChildRef(View v) {
    this.mnestedScrollingChildRef = new WeakReference<View>(v);
}

在您的Activity类中：

 RecyclerView recyGrid = (RecyclerView)findViewById(R.id.grid);
 RecyclerView recyList = (RecyclerView)findViewById(R.id.list);
 layout = (LinearLayout)findViewById(R.id.sliding_layout_container);

 recyGrid.addOnItemTouchListener(onItemTouchListener);
 recyList.addOnItemTouchListener(onItemTouchListener);

onItemTouchListener代码：

RecyclerView.OnItemTouchListener onItemTouchListener = new RecyclerView.OnItemTouchListener() {
    @Override
    public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {
        setScrollable(layout, rv);
        return false;
    }

    @Override
    public void onTouchEvent(RecyclerView rv, MotionEvent e) {

    }

    @Override
    public void onRequestdisallowInterceptTouchEvent(boolean disallowIntercept) {

    }
};

private void setScrollable(View bottomSheet, RecyclerView recyclerView){
    ViewGroup.LayoutParams params = bottomSheet.getLayoutParams();
    if (params instanceof CoordinatorLayout.LayoutParams) {
        CoordinatorLayout.LayoutParams coordinatorLayoutParams = (CoordinatorLayout.LayoutParams) params;
        CoordinatorLayout.Behavior behavior = coordinatorLayoutParams.getBehavior();
        if (behavior != null && behavior instanceof CustomBottomSheetBehavior)
            ((CustomBottomSheetBehavior)behavior).setnestedScrollingChildRef(recyclerView);
    }
}

我们在这里做的是捕获所有触摸事件,来到recyclerViews并将其作为mnestedScrollingChildRef添加到CustomBottomSheetBehavior类,以便可以正确的方式处理所有滚动事件.

更新于27.02.2018
在BottomSheetDialogFragment中使用这种方法涉及进一步的复制粘贴.我们应该创建CustomBottomSheetDialog,扩展AppCompatDialog并复制BottomSheetDialog类中的所有代码.然后将类变量mBehavior改为CustomBottomSheetBehavior,我在上面描述过.

然后,修改“wrapInBottomSheet”方法以在其中设置新行为：

ViewGroup.LayoutParams bottomSheetParams = bottomSheet.getLayoutParams();
    if (bottomSheetParams instanceof CoordinatorLayout.LayoutParams) {
        mBehavior = new CustomBottomSheetBehavior<>();
        mBehavior.setBottomSheetCallback(mBottomSheetCallback);
        mBehavior.setHideable(mCancelable);
        mBehavior.setPeekHeight(*some value here*);
        ((CoordinatorLayout.LayoutParams) bottomSheetParams).setBehavior(mBehavior);
    }

并在您的fragment类中重写“onCreateDialog”方法以使用CustomBottomSheetDialog：

  @NonNull
  @Override
  public Dialog onCreateDialog(Bundle savedInstanceState) {
    CustomBottomSheetDialog  dialog = new CustomBottomSheetDialog (getActivity(), R.style.YourDialogTheme);
    dialog.setContentView(R.layout.bottom_sheet_page_fragment);

     RecyclerView recyGrid = (RecyclerView)dialog.findViewById(R.id.grid);
     RecyclerView recyList = (RecyclerView)dialog.findViewById(R.id.list);
     layout = (LinearLayout)dialog.findViewById(R.id.sliding_layout_container);

     recyGrid.addOnItemTouchListener(onItemTouchListener);
     recyList.addOnItemTouchListener(onItemTouchListener);
     return dialog;
    }

其余代码保持不变.
