创建了一个列表，并使用RecyclerView自定义列表
这是代码：
activity_caddy.xml （CardView）：
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然后我有<?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>
这样的适配器：
RecyclerView
CaddyAdapter.java我希望通过点击buttoncaddy在我的CoForm上显示弹出窗口但是当我点击按钮时，只显示一个白色的空白弹出窗口..
这里是代码：
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;
/**

*/
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);
}
}
}
我该怎么做才能向我的弹出窗口显示数据列表？我该修什么？
答案 0 :(得分：0)
您在设置回收视图时确实将任何项目添加到列表中。您刚刚创建了这个ArrayList<Caddy> data = new ArrayList<>();，并且您已添加到列表中，因此大小将始终为＆＃34; 0＆＃34;。
case R.id.buttoncaddy:
//create dialog
final Dialog dialog = new Dialog(CoFormActivity.this);
//set layout custom
dialog.setContentView(R.layout.activity_caddy);
final RecyclerView rvcaddy = (RecyclerView) dialog.findViewById(R.id.rvcaddy);
ArrayList<Caddy> data = new ArrayList<>();
CaddyAdapter adapter = new CaddyAdapter(data, this, R.layout.activity_caddy);
// Add some item here to show the list.
rvcaddy.setAdapter(adapter);
RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(getApplicationContext());
rvcaddy.setLayoutManager(mLayoutManager);
dialog.show();
break;
