Question

如果它只是一个开端人和roid子方案拟定者,那么它会 Sor。

i 想作一系列信号级和切入点。稍后,我的目标是把这两个阵列安装到一个服务器上,利用JSON获得网络服务。 i 无法找到合适的办法,使阵列得以检索和roid提供的保护信息。评论见以下法典的收受方法中的陈述。

package com.example.jsonwifi;


public class JsonWifi extends Activity {
    TextView mainText;
    WifiManager mainWifi;
    WifiReceiver receiverWifi;
    List<ScanResult> wifiList;
    StringBuilder sb = new StringBuilder();
    String[] apmacs;
    String[] levels;

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    mainText = (TextView) findViewById(R.id.mainText);
    mainWifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);

    receiverWifi = new WifiReceiver();
    registerReceiver(receiverWifi, new IntentFilter(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION));
    mainWifi.startScan();
    mainText.setText("
Starting Scan...
");

似乎你想要在存储于<代码>的检索数据中架设阵列。 List<ScanResult>。 I d 初步确定名单的大小,将其放在正地一边......

See if this work.

    public void onReceive(Context c, Intent intent) {
            sb = new StringBuilder();
            wifiList = mainWifi.getScanResults();

            // initialize arrays here!
            apmacs = new String[wifiList.size( )];
            levels = new String[wifiList.size( )];

            for(int i = 0; i < wifiList.size(); i++){
                sb.append(new Integer(i+1).toString() + ".");
..... more appends....

               // populate the arrays                       
               apmacs[i]= wifiList.get(i).BSSID;
               levels[i] = String.valueOf( wifiList.get(i).level );
            }
