虽然我认为它比我想的更简单，但这有点令人困惑。
我有一个名为Commodities的类和一个名为Stops的类，停止类接收一系列商品。停止内部的所有项目都正确解析，如果我检查调试器上的停止类的内容，我可以看到它应该去的地方。问题在于知道从适配器获取什么，将用于显示Stops类及其内部Commodities addapter类的内容。
这是我的代码（简短）
首先是停止类
public class Stops implements Parcelable{
private String stop_id;
private String type;
private String location;
private String address;
private String city;
private String state;
private String zip;
private String from;
private String to;
private Commodities[] commodities;
public Stops() {}
public String getStop_id() {
return stop_id;
}
public void setStop_id(String stop_id) {
this.stop_id = stop_id;
}
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public String getLocation() {
return location;
}
public void setLocation(String location) {
this.location = location;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public String getCity() {
return city;
}
public void setCity(String city) {
this.city = city;
}
public String getState() {
return state;
}
public void setState(String state) {
this.state = state;
}
public String getZip() {
return zip;
}
public void setZip(String zip) {
this.zip = zip;
}
public String getFrom() {
return from;
}
public void setFrom(String from) {
this.from = from;
}
public String getTo() {
return to;
}
public void setTo(String to) {
this.to = to;
}
public Commodities[] getCommodities() {
return commodities;
}
public void setCommodities(Commodities[] commodities) {
this.commodities = commodities;
}
/**
* The content for the actual parcelables start in here
*
* */
@Override
public int describeContents() {
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeTypedArray(commodities,0);
dest.writeString(address);
}
private Stops(Parcel in){
commodities = in.createTypedArray(Commodities.CREATOR);
address = in.readString();
}
public static final Creator<Stops> CREATOR = new Creator<Stops>(){
@Override
public Stops createFromParcel(Parcel source) {
return new Stops(source);
}
@Override
public Stops[] newArray(int size){
return new Stops[size];
}
};
}
然后是商品类
public class Commodities implements Parcelable{
private String item;
private String description;
private String poNumber;
private String qty;
private String weight;
public Commodities() {}
public String getItem() {
return item;
}
public void setItem(String item) {
this.item = item;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public String getPoNumber() {
return poNumber;
}
public void setPoNumber(String poNumber) {
this.poNumber = poNumber;
}
public String getQty() {
return qty;
}
public void setQty(String qty) {
this.qty = qty;
}
public String getWeight() {
return weight;
}
public void setWeight(String weight) {
this.weight = weight;
}
@Override
public int describeContents() {
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(item);
dest.writeString(description);
dest.writeString(poNumber);
dest.writeString(qty);
dest.writeString(weight);
}
private Commodities(Parcel in){
item = in.readString();
description =in.readString();
poNumber = in.readString();
qty = in.readString();
weight = in.readString();
}
public static final Creator<Commodities> CREATOR = new Creator<Commodities>() {
@Override
public Commodities createFromParcel(Parcel source) {
return new Commodities(source);
}
@Override
public Commodities[] newArray(int size) {
return new Commodities[size];}
};
}
上述信息的适配器当前显示为：
公共类StopsAdapter扩展了RecyclerView.Adapter {
Stops[] como; // change this to stops and every other ocurrance of stops
public StopsAdapter(Stops[] comms){
como = comms;
}
@Override
public StopsViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.load_display_items, parent, false);
StopsViewHolder holder = new StopsViewHolder(view);
return holder;
}
@Override
public void onBindViewHolder(StopsViewHolder holder, int position) {
holder.bindStops(como[position]);
}
@Override
public int getItemCount() {
return como.length;
}
public class StopsViewHolder extends RecyclerView.ViewHolder {
public TextView mItem;
public StopsViewHolder(View itemView) {
super(itemView);
mItem = (TextView)itemView.findViewById(R.id.nameHolder);
}
public void bindStops(Stops stop) {
mItem.setText(stop.getAddress());
Log.d("<",mItem.getText().toString());
}
}
}
获取信息并启动适配器的活动：
public class LoadsActivity extends AppCompatActivity {
// et the gold juju
private Stops[] commodities;
@BindView(R.id.recyclerView) RecyclerView mRecyclerView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_loads);
ButterKnife.bind(this);
//get that intent parcelable juju mojo baby
Intent intent = getIntent();
Parcelable[] parcelable = intent.getParcelableArrayExtra(MainActivity.COMM_CONTENT);
commodities = Arrays.copyOf(parcelable, parcelable.length, Stops[].class);
//adapter bitches
StopsAdapter adapter = new StopsAdapter(commodities);
mRecyclerView.setAdapter(adapter);
RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(this);
mRecyclerView.setLayoutManager(layoutManager);
mRecyclerView.setHasFixedSize(true);
}
}
根据我在Stops类中的内容填充显示内容，这很好，像地址这样的变量（我在parcelable部分编码）会相应地显示，但我的问题基本上就是。我如何使用商品呢？如果我试着打电话（在停止适配器中）
mItem.setText(stop.getCommodities().getItem());
我收到一条错误，指出它无法解决商品类中的方法getItem（）。
基本上，我不知道如何从StopsAdapter中的商品中获取内容。
答案 0 :(得分：3)
函数getCommodities()返回一个数组。
public Commodities[] getCommodities() {
return commodities;
}
您应该从退回的商品中选择和项目，以便您可以访问该元素的信息
mItem.setText(stop.getCommodities()[index].getItem());
