Question

如果在理解如何解析数据时遇到问题，我有一个recycleview，它是从company数组中获取其文本集的，当用户单击某个卡时，该卡的companynumber应该附加到另一个我无法查询的URL上弄清楚怎么做谢谢您的帮助

@Override
public void onBindViewHolder(@NonNull final ViewHolder viewHolder, final int i) {
    //companyList= new ArrayList<Company>();

    Company company = companies.get(i);
    viewHolder.textViewHead.setText(company.getCompanyTitle());
    viewHolder.textviewDesc.setText(company.getCompanyType());
    viewHolder.textViewNumber.setText(company.getCompanyNumber());
    viewHolder.linearLayout.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            ///send these to nodes them attach the officers, get both in nodes and send to myview
            Company company1 = companies.get(i);
            Intent skipintent = new Intent(view.getContext(), Nodes.class);
            skipintent.putExtra(KEY_NAME, company1.getCompanyTitle());
            skipintent.putExtra(KEY_TYPE, company1.getCompanyType());
            skipintent.putExtra(KEY_NUMBER, company1.getCompanyNumber());
            //  view.getContext().startActivity(skipintent);
            Bundle bundle = new Bundle();
            bundle.putString(KEY_NAME, company1.getCompanyTitle());
            bundle.putString(KEY_TYPE, company1.getCompanyType());
            bundle.putString(KEY_NUMBER, company1.getCompanyNumber());
            skipintent.putExtras(bundle);
            new RetrieveFeedTask(//dont know what to put here).execute();


        }
    });


}

@Override
public int getItemCount() {
    return companies.size();
}

public class ViewHolder extends RecyclerView.ViewHolder {
    private TextView textViewHead;
    private TextView textviewDesc;
    private TextView textViewNumber;
    private LinearLayout linearLayout;

    public ViewHolder(@NonNull View itemView) {
        super(itemView);
        textViewHead = (TextView) itemView.findViewById(R.id.textviewhead);
        textviewDesc = (TextView) itemView.findViewById(R.id.textviewDesc);
        textViewNumber = (TextView) itemView.findViewById(R.id.textviewNumber);
        linearLayout = (LinearLayout) itemView.findViewById(R.id.linearLayout);

    }

}


    class RetrieveFeedTask extends AsyncTask<String, Void, String> {

        private Exception exception;

        protected String doInBackground(String... strings) {
           ///here i want to put the texviewnumber
            try {
                URL url = new URL(API_URL + textviewnumber +"/officers");
                HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
                try {

Answer 1

我认为您在创建网址时遇到问题。

首先，不要插入空格。

并且您没有得到textviewnumber文本。

尝试

URL url = new URL(API_URL + textviewnumber.getText() +"/officers");

我希望你完成工作。

Answer 2

您可以像这样将参数传递给asyncTask：

new RetrieveFeedTask().execute(myStringArrayParameter);

，您可以在asyncTask中访问以下内容：

URL url = new URL(API_URL + strings[0] +"/officers");

您的doInBackground（）方法如下所示：

doInBackground(String... strings)

这意味着您可以添加String数组作为参数。

将settext数据解析为urlconnect
