用于CardView的OnClickListener无法运行android？

Question

我有联系人列表,我已使用CardView在RecyclerView上显示此列表.

列表显示完美但现在我想制作可点击的卡片视图.因此,当我点击特定联系人时,我将显示特定联系人的详细信息.

列表完美显示,但当我点击特定联系人点击事件不起作用.

我还在ContactAdapter类的CardView和OnClickListener事件上使用了clickable true.

我做了什么 :

我有三个布局activity_main,contact_list,contact_detail.

在activity_main中,我使用了recycler_view.在contact_list中,我使用了card_view并将其与recycler视图绑定.

我有三个java类:Contact - 我在其中使用getter和setter定义变量ContactAdapter - 我获取联系人并将其与卡片视图绑定.MainActivity - 我获取所有联系人并在回收站视图中显示它.

activity_main布局代码:

<android.support.v7.widget.RecyclerView
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:id="@+id/recycler_view">

</android.support.v7.widget.RecyclerView>

contact_list_layout代码:

<android.support.v7.widget.CardView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/card_view"
    android:clickable="true">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1">

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Remo"
            android:id="@+id/person_name"/>

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_below="@id/person_name"
            android:text="example@gmail.com"
            android:id="@+id/person_email"/>

    </RelativeLayout>

</android.support.v7.widget.CardView>

Java类代码:

主要活动代码:

RecyclerView recyclerView;
RecyclerView.Adapter adapter;
RecyclerView.LayoutManager layoutManager;
String[] name,email;
ArrayList<Contact> list = new ArrayList<Contact>();

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    name = getResources().getStringArray(R.array.person_name);
    email = getResources().getStringArray(R.array.person_email);

    int count = 0;
    for (String Name : name)
    {
        Contact contact = new Contact(Name,email[count]);
        count++;
        list.add(contact);
    }
    recyclerView= (RecyclerView) findViewById(R.id.recycler_view);
    layoutManager = new LinearLayoutManager(this);
    recyclerView.setLayoutManager(layoutManager);
    recyclerView.setHasFixedSize(true);
    adapter=new ContactAdapter(list,this);
    recyclerView.setAdapter(adapter);
}

ContactAdapter代码:

 ArrayList<Contact> contacts = new ArrayList<Contact>();
Context ctx;

public ContactAdapter(ArrayList<Contact> contacts, Context ctx) {
    this.contacts = contacts;
    this.ctx = ctx;
}

@Override
public ContactViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.contact_list_layout, parent, false);
    ContactViewHolder contactViewHolder = new ContactViewHolder(view, ctx, contacts);
    return contactViewHolder;
}

@Override
public void onBindViewHolder(ContactViewHolder holder, int position) {
    Contact CON = contacts.get(position);
    holder.person_name.setText(CON.getName());
    holder.person_email.setText(CON.getEmail());
}

@Override
public int getItemCount() {
    return contacts.size();
}

public static class ContactViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
    TextView person_name, person_email;
    ArrayList<Contact> contacts = new ArrayList<Contact>();
    Context ctx;

    public ContactViewHolder(View view, Context ctx, ArrayList<Contact> contacts) {
        super(view);
        this.contacts = contacts;
        this.ctx = ctx;
        person_name = (TextView) view.findViewById(R.id.person_name);
        person_email = (TextView) view.findViewById(R.id.person_email);
    }

    @Override
    public void onClick(View v) {
        int position = getAdapterPosition();
        Contact contact = this.contacts.get(position);
        Intent intent =new Intent(this.ctx,ContactDetail.class);
        this.ctx.startActivity(intent);
    }
}

我删除android:clickable="true"项目视图时修复了同样的问题.

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="@dimen/item_dashboard_size"
    android:layout_margin="@dimen/item_dashboard_margin">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="?selectableItemBackground"
        android:padding="@dimen/item_dashboard_padding">
    .....
</android.support.v7.widget.CardView>
