我有一个阵列

char* temp;
temp=kmalloc(3,GFP_KERNEL);

我需要在每次调用此函数时展开此数组注意:Realloc不能在linux内核中使用我不知道它是否存在

我正在尝试在Android客户端和C#Server之间建立连接..我的服务器工作正常,除非Android客户端即使在添加了Internet连接权限后也无法正常工作

这是代码:

    private void connectSocket(String a){ 

    try { 
        InetAddress serverAddr = InetAddress.getByName("192.168.0.2"); 
        Log.d("TCP", "C: Connecting....");

        Socket socket = new Socket(serverAddr,4444); 
        Log.d("TCP", "C: I dunno ...");
        //String message = "1";

        PrintWriter out = null;
        BufferedReader in = null;

        try { 
          //  Log.d("TCP", "C: Sending: '" + message + "'"); 
            out = new PrintWriter( new BufferedWriter( new OutputStreamWriter(socket.getOutputStream())),true); 
            in = new BufferedReader(new InputStreamReader(socket.getInputStream()));                

            //out.println(message);
            while ((in.readLine()) != null) {
            txt.append(in.readLine());
            }

            Log.d("TCP", "C: Sent."); 
            Log.d("TCP", "C: Done.");               

        } catch(Exception e) { 
            Log.e("TCP", …

我在函数内使用AsyncTask如何在异步完成执行时返回一个值,因为我不能在这里使用PostExecute方法

AsyncTask.execute(new Runnable() {
            public void run() {}}

继承人守则.我需要从SpinnerList检索值以在主线程上使用em.但是,每当我要求数据时,通常我会得到空值,因为它还没有返回值.

AsyncTask.execute(new Runnable() {
            public void run() {
                try{
                    String fql = "SELECT uid, name FROM user WHERE is_app_user  AND uid IN (SELECT uid2 FROM friend WHERE uid1 = me())";
                    Bundle parameters = new Bundle();

                    parameters.putString("query", fql);
                    parameters.putString("method", "fql.query");
                    parameters.putString("access_token",  fb.getAccessToken());
                    String Response = fb.request(parameters);
                    JSONArray json = new JSONArray(Response);
                    list = new ArrayList<String[][]>();
                    String[][] friendsToList = new String[1][2];
                    SpinnerList = new ArrayList<String>();
                    String TempToSpinnerList=new String();
                    for(int i = 0; i < …
