我的手机管家（12） 网络助手 逻辑代码
public class
提供网络流量统计的类。这些统计数据包括字节发送和接收网络发送和接收的数据包，
在所有的接口，在手机界面，并对每一个用户基础。
这些统计数据可能无法在所有平台上使用。如果该设备不支持统计数据，则将返回 UNSUPPORTED 。
接收和发送数据包
static long getMobileRxPackets()
自设备启动后的整个移动网络中接收的数据包的返回数。
static long getMobileTxPackets()
发送
接收和发送的字节数
static long getMobileRxBytes()
接收
static long getMobileTxBytes()
自启动设备启动后的移动网络中传输的字节数。
给定的uid的应用接收和发送的字节数
getUidRxBytes(int uid) 接收
getUidTxBytes(int uid) 发送
/** *获取使用流量信息 */ private final Runnable runnable = new Runnable(){ public void run() { final PackageManager pm = NetworkHelperActivity.this.getPackageManager(); ArrayList<ResolveInfo> trafficlists = new ArrayList<ResolveInfo>(); Intent intent = new Intent(); intent.setAction("android.intent.action.MAIN"); intent.addCategory("android.intent.category.LAUNCHER"); final List<ResolveInfo> lists = pm.queryIntentActivities(intent, 0); for(ResolveInfo info : lists){ if(TrafficStats.getUidRxBytes(info.activityInfo.applicationInfo.uid) != -1 && TrafficStats.getUidTxBytes(info.activityInfo.applicationInfo.uid) != -1){ trafficlists.add(info); } } //初始化适配器，并绑定 adapter = new MyNetworkAdapter(NetworkHelperActivity.this,trafficlists); lv.setAdapter(adapter); } } ;
