android系统中远程服务器文本数据的收发

Question

嗨，我创建了一个应用程序，我隐藏了编辑文本框和两个按钮，在我点击按钮事件后，文本框将在运行时弹出，它工作正常，但我需要输入的文本应该传递给服务器，帮助我。欢迎所有的想法

Answer 1

如果我没理解错的话，您的文本框中有文本，并且您希望将该数据发送到服务器。您可以查看以下教程/片段之一，了解如何将数据发布到web服务器：

或Secure HTTP Post in Android

Answer 2

可以使用JSON或XML将数据发送到远程服务器。

嗨，这段代码将把你的数据发送到用edittext编写的服务器。对于textview，只需将edittext的名称改为textview的名称即可。代码如下：

package com.example.asynchttppost;

import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

import org.apache.http.HttpResponse;
import org.apache.http.NameValuePair;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.message.BasicNameValuePair;

import android.app.Activity;
import android.os.AsyncTask;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ProgressBar;
import android.widget.Toast;

public class MainActivity extends Activity implements OnClickListener{

    private EditText value;
    private Button btn;
    private ProgressBar pb;
        private TextView tv;


    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        value=(EditText)findViewById(R.id.editText1);
        btn=(Button)findViewById(R.id.button1);
        pb=(ProgressBar)findViewById(R.id.progressBar1);
                tv =(TextView)findViewById(R.id.TextView1);
        pb.setVisibility(View.GONE);
        btn.setOnClickListener(this);
    }


    public void onClick(View v) {
        // TODO Auto-generated method stub
            if(value.getText().toString().length()<1){

                // out of range
                Toast.makeText(this, "please enter something", Toast.LENGTH_LONG).show();
            }else{
                pb.setVisibility(View.VISIBLE);
                new MyAsyncTask().execute(value.getText().toString());      
            }


    } 

    private class MyAsyncTask extends AsyncTask<String, Integer, Double>{

        @Override
        protected Double doInBackground(String... params) {
            // TODO Auto-generated method stub
            postData(params[0]);
            return null;
        }

        protected void onPostExecute(Double result){
            pb.setVisibility(View.GONE);
            Toast.makeText(getApplicationContext(), "Code Sent", Toast.LENGTH_LONG).show();
        }
        protected void onProgressUpdate(Integer... progress){
            pb.setProgress(progress[0]);
        }

        public void postData(String valueIWantToSend) {
            // Create a new HttpClient and Post Header
            HttpClient httpclient = new DefaultHttpClient();
            //HttpPost httppost = new HttpPost("http://10.0.2.2/chotu/index.php");
            HttpPost httppost = new HttpPost("http://192.168.1.13/educlinic/Widget/AndroidApp");
            try {

                // Add your data
                List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
                nameValuePairs.add(new BasicNameValuePair("myHttpData", valueIWantToSend));
                httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

                // Execute HTTP Post Request
                HttpResponse response = httpclient.execute(httppost);

            } 
            catch (ClientProtocolException e) 
            {
                // TODO Auto-generated catch block
            } catch (IOException e)
            {
                // TODO Auto-generated catch block
            }
        }

    }
}
