我使用RecyclerView製作了一個列表，並使用CardView自定義列表。
下面的代碼：如何在彈出對話框中顯示Recycler視圖？
activity_caddy.xml（在RecyclerView）：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@android:color/white"
android:orientation="vertical"
tools:context="com.example.user.ayogolf.CaddyActivity">
<android.support.v7.widget.RecyclerView
android:layout_width="368dp"
android:layout_height="551dp"
android:id="@+id/rvcaddy"
tools:layout_editor_absoluteY="8dp"
tools:layout_editor_absoluteX="8dp"></android.support.v7.widget.RecyclerView>
</LinearLayout>
activity_custom_list_caddy.xml：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:background="@android:color/white"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="8dp"
app:cardBackgroundColor="@color/cardview_light_background"
app:cardCornerRadius="10dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
>
<ImageView
android:id="@+id/imgcaddy"
android:layout_width="96dp"
android:layout_height="96dp"
android:layout_margin="6dp"
android:src="@drawable/no_photo" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:id="@+id/txtcaddy_name"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="8dp"
android:text="Caddy Name"
android:textSize="18sp"
android:textStyle="bold"
android:textColor="@android:color/black"/>
<TextView
android:id="@+id/txtgender"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="8dp"
android:text="Gender"
android:textSize="15sp"
android:textColor="@android:color/black"/>
</LinearLayout>
</LinearLayout>
</android.support.v7.widget.CardView>
</LinearLayout>
，然後我對RecyclerView像這樣的適配器：
CaddyAdapter.java
package com.example.user.ayogolf;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;
import com.bumptech.glide.Glide;
import com.example.user.ayogolf.Retrofit.Caddy;
import java.util.ArrayList;
/**
* Created by arifina on 7/26/2017.
*/
public class CaddyAdapter extends RecyclerView.Adapter<CaddyAdapter.MyHolder>{
ArrayList<Caddy> data;
RecyclerView r;
Context c;
int resource;
public CaddyAdapter(ArrayList<Caddy> data, Context c, int resource) {
this.data = data;
//this.r = r;
this.c = c;
this.resource=resource;
}
View.OnClickListener listener = new View.OnClickListener() {
@Override
public void onClick(View v) {
//array position
int posisi = r.getChildLayoutPosition(v);
Intent intent = new Intent(c,CoFormActivity.class);
intent.putExtra("pic",data.get(posisi).getCaddy_pic());
intent.putExtra("name",data.get(posisi).getCaddy_name());
intent.putExtra("gender",data.get(posisi).getGender());
c.startActivity(intent);
}
};
@Override
public CaddyAdapter.MyHolder onCreateViewHolder(ViewGroup parent, int viewType) {
LayoutInflater inflater = (LayoutInflater) c.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View v = inflater.inflate(R.layout.activity_custom_list_caddy,parent,false);
v.setOnClickListener(listener);
return new MyHolder(v);
}
@Override
public void onBindViewHolder(CaddyAdapter.MyHolder holder, int position) {
holder.textnama.setText(data.get(position).getCaddy_name());
holder.textgender.setText(data.get(position).getGender());
Glide.with(c)
.load("http://192.168.2.32/ayogolf/uploads/caddy/"+data.get(position).getCaddy_pic())
.into(holder.image);
}
@Override
public int getItemCount() {
return data.size();
}
public class MyHolder extends RecyclerView.ViewHolder {
ImageView image;
TextView textnama;
TextView textgender;
public MyHolder(View itemView) {
super(itemView);
image = (ImageView) itemView.findViewById(R.id.imgcaddy);
textnama = (TextView) itemView.findViewById(R.id.txtcaddy_name);
textgender = (TextView) itemView.findViewById(R.id.txtgender);
}
}
}
，我想通過點擊buttoncaddy但是當我按一下按鈕，還有的只顯示一個白色的空白的彈出窗口，以顯示我的同成形彈出..

我應該怎麼做才能顯示彈出式數據列表？我應該修理什麼東西？
