我的主要活动MainActivity.java
my Main Activity, MainActivity.java

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;

数据对象ailment.java
the Data object, ailment.java
package com.example.visan.newappfireui;
public class ailment {
private String name;
private String img;
public ailment(){
}
public ailment(String name,String img){
this.name=name;
this.img=img;

}

this.name=name;
}
public String getImg(){

}
public void setImg(String img){

}
}
两个布局文件， 这是针对主要活动，activity_main.xml
The two layout files, This one is for the Main Activity, activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.example.visan.newappfireui.MainActivity">
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/recycler"/>
</RelativeLayout>
这是针对回收站视图的行，recycler_row.xml
This is for the row of the recycler view, recycler_row.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:srcCompat="@drawable/common_full_open_on_phone"
android:layout_alignParentTop="true"
android:layout_alignParentStart="true"
android:id="@+id/imageView" />
<TextView
android:text="TextView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/imageView"
android:layout_alignParentStart="true"
android:id="@+id/textView" />
</RelativeLayout>
修改:依赖项
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.google.firebase:firebase-storage:10.0.1'
compile 'com.google.firebase:firebase-auth:10.0.1'
compile 'com.google.firebase:firebase-database:10.0.1'
compile 'com.firebaseui:firebase-ui-database:1.0.1'
compile 'com.firebaseui:firebase-ui-storage:1.0.1'
compile 'com.android.support:support-v4:23.4.0'
compile 'com.squareup.picasso:picasso:2.5.2'
testCompile 'junit:junit:4.12'
}
推荐答案
您的DataHolder应该如此公开
public static class DataHolder extends RecyclerView.ViewHolder{...}
