在卡片视图中使回收者视图可点击

<android.support.v7.widget.CardView xmlns:card_view="http://schemas.android.com/apk/res-auto" android:id="@+id/home_subscribe_card" android:layout_width="match_parent" android:layout_height="72dp" android:onClick="@{vm.onGoalPress}" card_view:cardCornerRadius="4dp"> <android.support.v7.widget.RecyclerView android:id="@+id/feeds_list" android:layout_width="200dp" android:layout_height="30dp" android:layout_marginTop="6dp" /> </CardView> 

Click上的卡片视图正在工作，但回收者视图的区域不可点击。 如何使它成为可点击的，以便捕捉卡片视图的事件。

Answer 1

对于recylerview你需要设置适配器的顺序来使用可点击的列表视图。 你可以参考下面的链接： https : //developer.android.com/training/material/lists-cards.html你可以看看另一个问题在这里： 为什么不RecyclerView有onItemClickListener（）？ RecyclerView和Listview有什么不同？

  protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.my_activity); mRecyclerView = (RecyclerView) findViewById(R.id.my_recycler_view); // use this setting to improve performance if you know that changes // in content do not change the layout size of the RecyclerView mRecyclerView.setHasFixedSize(true); // use a linear layout manager mLayoutManager = new LinearLayoutManager(this); mRecyclerView.setLayoutManager(mLayoutManager); // specify an adapter (see also next example) mAdapter = new MyAdapter(myDataset); mRecyclerView.setAdapter(mAdapter); } public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> { private String[] mDataset; // Provide a reference to the views for each data item // Complex data items may need more than one view per item, and // you provide access to all the views for a data item in a view holder public static class ViewHolder extends RecyclerView.ViewHolder { // each data item is just a string in this case public TextView mTextView; public ViewHolder(TextView v) { super(v); mTextView = v; } } // Provide a suitable constructor (depends on the kind of dataset) public MyAdapter(String[] myDataset) { mDataset = myDataset; } // Create new views (invoked by the layout manager) @Override public MyAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { // create a new view View v = LayoutInflater.from(parent.getContext()) .inflate(R.layout.my_text_view, parent, false); // set the view's size, margins, paddings and layout parameters ... ViewHolder vh = new ViewHolder(v); return vh; } // Replace the contents of a view (invoked by the layout manager) @Override public void onBindViewHolder(ViewHolder holder, int position) { // - get element from your dataset at this position // - replace the contents of the view with that element holder.mTextView.setText(mDataset[position]); } // Return the size of your dataset (invoked by the layout manager) @Override public int getItemCount() { return mDataset.length; } 

}

//像这样//holder.mTextView.setOnClickListener（onClick）;

 public class InterceptTouchCardView extends CardView { public InterceptTouchCardView(Context context) { super(context); } public InterceptTouchCardView(Context context, AttributeSet attrs) { super(context, attrs); } public InterceptTouchCardView(Context context, AttributeSet attrs, int defStyleAttr) { super(context, attrs, defStyleAttr); } /** * Intercept touch event so that inner views cannot receive it. * * If a ViewGroup contains a RecyclerView and has an OnTouchListener or something like that, * touch events will be directly delivered to inner RecyclerView and handled by it. As a result, * parent ViewGroup won't receive the touch event any longer. */ @Override public boolean onInterceptTouchEvent(MotionEvent ev) { return true; } 

}

您需要在recyclerview适配器的视图中设置点击侦听器。 在Viewholder中，你可以访问每个视图的所有元素，即循环查看器膨胀的layoyt的Viewgroup。 我希望这是有道理的。

或者，您可以在onBind（）方法中设置onclick监听器。

如果您的卡片视图在回收站视图之外，则无法直接访问它。 从回收站视图中使用回电或活动巴士到您正在充值卡片视图的活动/片段，然后使用新值更新卡片视图

当“RecyclerView”的项目本身具有一些可点击的视图（即按钮）时，具有“InterceptTouchCardView”的组合具有问题。 那些可点击的视图从来不会收到任何触摸事件。 更好的解决方法是扩展RecyclerView并覆盖它的onInterceptTouchEvent和onTouchEvent，所以它们都只是像这样（Kotlin语法）返回false：

 class ClickThroughRecyclerView : RecyclerView { constructor(context: Context) : super(context) constructor(context: Context, attr: AttributeSet?) : super(context, attr) constructor(context: Context, attr: AttributeSet?, defStyle: Int) : super(context, attr, defStyle) override fun onInterceptTouchEvent(e: MotionEvent): Boolean { return false } override fun onTouchEvent(e: MotionEvent): Boolean { return false } } 

通过在布局文件中使用ClickThroughRecyclerView可以确保RecyclerView的项目（如按钮，…）不消耗的触摸事件被传播到RecyclerView的父视图。
