Question

我试图从android中的设置页面获取3g和wifi使用，无论如何要做到这一点，我可以设置一个意图设置数据使用页面，代码如下;

Intent intent = new Intent();
    intent.setComponent(new ComponentName("com.android.settings","com.android.settings.Settings$DataUsageSummaryActivity"));

    startActivity(intent);

但是有没有办法达到这些意图的组件并从这些组件中获取数据。

Thankss ..

是的，您可以通过编程方式获取数据使用情况

// Get running processes
ActivityManager manager = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
List<RunningAppProcessInfo> runningApps = manager.getRunningAppProcesses();

for (RunningAppProcessInfo runningApp : runningApps) {

  // Get UID of the selected process
  int uid = ((RunningAppProcessInfo)getListAdapter().getItem(position)).uid;

  // Get traffic data
  long received = TrafficStats.getUidRxBytes(uid);
  long send   = TrafficStats.getUidTxBytes(uid);
  Log.v("" + uid , "Send :" + send + ", Received :" + received);
}

试试这种方式您也可以参考本教程 http://www.techrepublic.com/blog/software-engineer/create-a-network-monitor-using-androids-trafficstats-class/
