如何从Android中的设置获取数据使用情况 [英] how to get data usage from settings in android

问题描述

我正在尝试从android的设置"页面获取3g和wifi的使用情况，无论如何，我可以设置一个意图设置数据使用情况页面，代码如下；

I'm trying to get 3g and wifi usage from Settings page in android, is there anyway to do that, i can set an intent Settings data usage page, code is below;

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

    startActivity(intent);

但是有什么方法可以达到这些意图的组成部分，并从这些组成部分中获取数据.

But is there any way to reach these intent's component and to get data from those components.

推荐答案

是的，您可以通过编程方式获取数据使用量

Yes you can programmatically get the data usage

// 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);
}
