是否解决了？ –

修改您的异步任务是这样的：在非UI线程中执行asynctask的背景方法，因此我们不能修改doInbackgroud中的ui元素，所以我们必须返回结果，以便postExecute方法中的结果作为参数那么我们可以修改UI

package com.example.phonebook; 

    import java.util.ArrayList; 
import java.util.List; 

import org.apache.http.message.BasicNameValuePair; 
import org.json.JSONObject; 

import android.app.Activity; 
import android.os.AsyncTask; 
import android.os.Bundle; 
import android.os.StrictMode; 
import android.util.Log; 
import android.widget.TextView; 

import com.afbb.animationtest.R; 

    public class Welcome extends Activity { 
     TextView jsonParsed1,DataShow,hint_data; 
     TextView jsonParsed ; 
     JSONParser jsonParser = new JSONParser(); 
     JSONParser jobj = new JSONParser(); 
     private static String url = "http://192.168.1.10/android_connect/login_setup/show_data.php"; 
     @Override 
     protected void onCreate(Bundle savedInstanceState) { 
      StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder() 
      .detectDiskReads().detectDiskWrites().detectNetwork() 
      .penaltyLog().build()); 
      super.onCreate(savedInstanceState); 
      setContentView(R.layout.welcome); 
      jsonParsed1=(TextView)findViewById(R.id.jsonParsed); 
      DataShow=(TextView)findViewById(R.id.show_all_data); 
      hint_data=(TextView)findViewById(R.id.hint_datafor_value); 
      jsonParsed = (TextView) findViewById(R.id.jsonParsed); 
      String abt = getIntent().getStringExtra("mobile_number"); 
      new loginAccess().execute(); 
     } 

    class loginAccess extends AsyncTask<String,Void,JSONObject> { 
     private String Content; 
     @Override 
     protected JSONObject doInBackground(String... arg0) { 
      String abt = getIntent().getStringExtra("mobile_number"); 
      List params = new ArrayList(); 
      params.add(new BasicNameValuePair("mobile_number", abt)); 
      JSONObject json = jsonParser.makeHttpRequest(url,"POST", params); 
       Content = json.toString(); 
       Log.d("Create Response", Content); 
    /****************** Start Parse Response JSON Data *************/ 
       try { 
        JSONObject jsonResponse = new JSONObject(Content); 
        String hint = jsonResponse.optString("hint").toString(); 
        return jsonResponse; 
       } catch (Exception e) { 

        e.printStackTrace(); 
       } 
       return null; 
     } 
     protected void onPostExecute(JSONObject result) { 
      //Parse and update the UI 
       jsonParsed.setText(OutputData); 
      } 
     } 
    }

问我清楚我没有得到你。 –

显示您的修改代码。 –

我如何在欢迎活动中展示这些数据..... ?? ..不只显示一个数据{“3”：“[email protected]”，“2”：“myname”，“1” ： “msnmsn”， “0”： “8527801400”， “MOBILE_NUMBER”： “8527801400”， “提示”： “MYNAME”， “EMAIL_ID”： “[email protected]”， “密码”： “msnmsn” } –

jsonParsed.setText(OutputData);
你只要把上面一行在onPostExecute方法0123后线，你会得到完美的输出。
并且还从doInBackground删除jsonParsed.setText(OutputData);行的方法。

我改变你说什么，但数据不是完美的...你可以设置活动...深梅赫爵士 –

编辑该问题就像你说的 –

Log.i（“JSON解析”，提示）;在jsonParsed.setText（OutputData）之前，将此行放在onPostExecute方法中;行，你会得到我认为的解决方案。只需检查将此日志放在onPostExecute方法后，您将获得logcat中的数据或不！ –

低于线从doInBackground方法

jsonParsed.setText(OutputData);

你不能碰从外部主线程视图删除。
