Click上的卡片视图正在工作。但是，Recycler视图的区域不可点击。如何使其可点击以便捕获卡片视图事件。

Answer 1

对于recylerview，您需要设置适配器顺序以使用listview之类的可点击。您可以参考以下链接：https://developer.android.com/training/material/lists-cards.html 您可以在此处查看另一个问题：Why doesn't RecyclerView have onItemClickListener()? And how RecyclerView is different from Listview?

 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;
}

}

//像这样的东西 //holder.mTextView.setOnClickListener(onClick）;

Answer 2

您需要在recyclerview适配器的视图中设置单击侦听器。在Viewholder中，您可以访问每个视图的所有元素，即recyclerview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侦听器。

如果您的cardview在回收者视图之外，则无法直接访问它。使用回收站视图中的回拨或事件总线，以及您为卡片视图充气的活动/片段，然后使用新值更新卡片视图

Answer 3

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;
}

}

Answer 4

使用＆＃34; InterceptTouchCardView＆＃34;当RecyclerView的项目本身具有一些可点击的视图（即按钮）时会出现问题。那些可点击的视图从此不会收到任何触摸事件。更好的方法是扩展RecyclerView并覆盖它的onInterceptTouchEvent和onTouchEvent，这样它们就像这样返回false（Kotlin语法）：

aSwitch.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
    @Override
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

        Log.d("2^^list is ",String.valueOf(mAdapter.getItemCount()));

        if (!isChecked) {
            Log.d("notchecked","yo");
            mAdapter.getFilter().filter("");
        } else {
            mAdapter.getFilter().filter("credit");
        }
        recyclerView.setAdapter(mAdapter);
        mPassDataToActivity.passDataToActivity(someValue,mAdapter);
    }
});

通过在布局文件中使用ClickThroughRecyclerView确保，RecyclerView项目（如按钮，...）未使用的触摸事件将传播到RecyclerView的父视图。
