我有一个Cardview巴顿

卡视图布局

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
      xmlns:card_view="http://schemas.android.com/apk/res-auto" 
      android:layout_width="match_parent"

      <TextView 
       android:id="@+id/post_title"

       android:textSize="20sp"/> 
     </LinearLayout> 

     <RelativeLayout 
      android:layout_width="wrap_content" 
      android:layout_height="120dp" 
      > 
     <Button 
      android:id="@+id/expand" 
      android:layout_width="40dp" 
      android:layout_height="37dp"

      android:layout_alignParentStart="true"/> 
     </RelativeLayout> 

    </LinearLayout> 

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

PostCardAdapter.java

@Override 
    public void onBindViewHolder(ContactViewHolder holder, int position) { 
    ...... 
    holder.btn_expand.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      //for showing details of item on dialog 
      listener.onItemClicked(view); 
     } 
    }); 

} 

Recyclerview item click

listener = this; 
    mRecyclerView = (RecyclerView) findViewById(R.id.cardlist_posts); 
    mRecyclerView.setHasFixedSize(true); 
    mRecyclerView.setLayoutManager(new LinearLayoutManager(this)); 
    mRecyclerView.setItemAnimator(new DefaultItemAnimator()); 
    mRecyclerView.setAdapter(new PostCardAdapter(listener,db.getAllPosts(), R.layout.cardview_post)); 


    mRecyclerView.addOnItemTouchListener(
      new RecyclerItemClickListener(this, new RecyclerItemClickListener.OnItemClickListener() { 
       @Override 
       public void onItemClick(View view, int id) { 
        // TODO Handle item click 
        Intent intent = new Intent(MainActivity.this, ShowPostDetails.class); 
        intent.putExtra("KEY_POST_ID", String.valueOf(id + 1)); 
        System.out.println(String.valueOf(id + 1)); 
        //Starting another activity to show post details 
        startActivity(intent); 

       } 
      }) 
    ); 

MainActivity.java

@Override 
public void onItemClicked(View v) { 
    DialogPostFragment df= new DialogPostFragment(); 
    df.show(getFragmentManager(), "Dialog"); 
} 

当按下按钮，然后cardview项目被点击和持续回对话框也将打开。 我只想按下按钮时打开对话框。 谢谢。

我正好面临着同样的问题once.This是我如何解决它：

添加ID到第一线布局cardview内：现在

<LinearLayout 
     android:id="@+id/rowLL" 
     android:layout_width="fill_parent" 
     android:layout_height="123dp" 
     android:background="@drawable/posts_card_bg" 
     android:orientation="horizontal" 
     android:paddingBottom="3dp" 
     android:paddingRight="3dp" 
     > 

，在你PostCardAdapter的.java：

public class PostCardAdapter extends RecyclerView 
     .Adapter<ContactViewHolder> { 

    ... 

    private static MyClickListener myClickListener; 

    ... 

    public void setOnItemClickListener(MyClickListener myClickListener) { 
     PostCardAdapter.myClickListener = myClickListener; 
    } 

    ...   

    public interface MyClickListener { 
     public void onItemClick(int position, View v); 
    } 
} 

然后，在你ContactViewHo lder连续的.java

public class ContactViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{ 

     private PostCardAdapter.MyClickListener myClickListener; 

     ... 

     public ContactViewHolder(final Context context, View itemView, PostCardAdapter.MyClickListener clickListener) { 
      super(itemView); 
      ... 
      myClickListener = clickListener; 
      itemView.findViewById(R.id.rowLL).setOnClickListener(this); 
     } 

     @Override 
     public void onClick(View v) { 
      myClickListener.onItemClick(getLayoutPosition(), v); 
     } 
}
