篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Android项目实战--手机卫士34--流量管理相关的知识,希望对你有一定的参考价值。
最新实战教程,让你了解Android自动化刷量、作弊与防作弊的那些事,案例:刷友盟统计、批量注册苹果帐号
之前一直忙着找工作,所有都没有时间更新这个系列了,不过其实也差不多要完成的了,后面的一些都是一些比较零散的东西了
好了,不多说,现在就进入我们的正题,今天我们就讲一下那个流量管理的功能,其实流量管理并不难,android里面已经有自己的api的了
但由于它里面有一些东西,我也弄不明白,所以今天这个只是一个简单的示例,大家回去之后想继续完善的话,就要自己花时间研究一下了
好,我们先来看一下是我们要实现的界面
我们要实现的界面就是这样的了,我们使用一个抽屉的控件
首先,我们先来建一个model类,用来存放我们要显示的信息
com.xiaobin.security.domain.TrafficInfo
package com.xiaobin.security.domain;
import android.graphics.drawable.Drawable;
public class TrafficInfo
private String name;
private Drawable icon;
private int uid;
public String getName()
return name;
public void setName(String name)
this.name = name;
public Drawable getIcon()
return icon;
public void setIcon(Drawable icon)
this.icon = icon;
public int getUid()
return uid;
public void setUid(int uid)
this.uid = uid;
上面的那个uid就是我们的应用在android里面的uid啦,它从一装进手机里面开始,就不会变化的啦
写完model类之后,我们就先来写一下界面吧,我们这次,用到了一个控件,叫抽屉(SlidingDrawer),下面我把我们的布局文件粘出来
traffic_manager.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="40dip"
android:background="@drawable/title_background"
android:gravity="center_vertical|center_horizontal"
android:orientation="horizontal" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/traffic_manager"
android:textColor="@android:color/white"
android:textSize="22sp" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<TextView
android:id="@+id/tv_traffic_2g_3g"
android:layout_width="0dip"
android:layout_height="wrap_content"
android:layout_weight="1"
android:paddingLeft="8dip"
android:text="@string/traffic" />
<TextView
android:id="@+id/tv_traffic_wifi"
android:layout_width="0dip"
android:layout_height="wrap_content"
android:layout_weight="1"
android:paddingLeft="8dip"
android:text="@string/traffic" />
</LinearLayout>
<SlidingDrawer
android:layout_width="match_parent"
android:layout_height="match_parent"
android:content="@+id/lv_traffic_content"
android:handle="@+id/iv_traffic_handle"
android:orientation="vertical" >
<ImageView
android:id="@id/iv_traffic_handle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:contentDescription="@string/hello_world"
android:src="@drawable/handle" />
<ListView
android:id="@id/lv_traffic_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:cacheColorHint="@android:color/white" />
</SlidingDrawer>
</LinearLayout>
在SlidingDrawer这个节点里面,大家要注意了,我们必须要给它指定一个handle和content的,不然,它是会报错的
好啦,节点写好之后,我们就可以写我们的逻辑啦
首先,我们就要先拿到我们总的流量啦
private void setTotalTraffic()
//拿到2G和3G的总共接收到的数据大小
long total_2g_3g_received = TrafficStats.getMobileRxBytes();
//拿到2G和3G的总共发送出去的数据大小
long total_2g_3g_transmitted = TrafficStats.getMobileTxBytes();
//拿到2G和3G的总数据大小
long total_2g_3g = total_2g_3g_received + total_2g_3g_transmitted;
tv_traffic_2g_3g.setText("2G/3g 总流量:" + TextFormater.dataSizeFormat(total_2g_3g));
//拿到总共接收到的数据大小
long total_received = TrafficStats.getTotalRxBytes();
//拿到总共发送的数据大小
long total_transmitted = TrafficStats.getTotalTxBytes();
//拿到总数据大小
long total = total_received + total_transmitted;
拿到wifi的总数据大小
long total_wifi = total - total_2g_3g;
tv_traffic_wifi.setText("wifi 总流量:" + TextFormater.dataSizeFormat(total_wifi));
其实Android有一个类就是用来获取这些流量的信息的,TrafficStats
就这样,我们就可以拿到了wifi和2g/3g的总流量的了
注意,这个流量是会随着你每一次关机,都会设置为0的,也就是说,当你关机一次之后,这个值就是变成0的啦,所有要做一个流量管理的,就要把以前的也记录下来,然后再进行统计了
好啦,拿到了,总的流量之后,我们就要来拿到对应的一个个应用的流量了
首先,我们会先拿到一个会首先流量信息的应用列表先的
//拿到所有会产生流量的应用信息
private void initResolveInfos()
trafficInfos.clear();
//拿到一个包管理器
PackageManager packageManager = this.getPackageManager();
Intent intent = new Intent();
//android.intent.action.MAIN这个action代表的就是应用的入口
intent.setAction("android.intent.action.MAIN");
//android.intent.category.LAUNCHER代表的就是在桌面创建一个图标
intent.addCategory("android.intent.category.LAUNCHER");
//这个方法就是根据对应的条件,intent指定条件,然后查询出相应的activity
//那么根据我们上面设置的intent,我们就可以知道,我们要查询的是应用的入口activity而且是桌面上有图标的activity
//因为这样的应用,才会有可能产生流量的
List<ResolveInfo> resolveInfos = packageManager.queryIntentActivities(intent, 0);
for(ResolveInfo resolveInfo : resolveInfos)
//得到应用的名字
String name = resolveInfo.loadLabel(packageManager).toString();
//得到应用的图标
Drawable icon = resolveInfo.loadIcon(packageManager);
//得到应用的包名
String packageName = resolveInfo.activityInfo.packageName;
int uid = 0;;
try
//得到应用的packageInfo对象
PackageInfo packageInfo = packageManager.getPackageInfo(packageName, 0);
//得到这个应用对应的uid
uid = packageInfo.applicationInfo.uid;
//根据uid得到这个应用的接收数据大小
long received = TrafficStats.getUidRxBytes(uid);
//根据uid得到这个应用的发送数据大小
long transmitted = TrafficStats.getUidTxBytes(uid);
//有些应用不会产生流量信息的,拿到的值就会是-1
//不产生流量的,我们就不把它加入到list里面
if(received == -1 && transmitted == -1)
continue;
catch (NameNotFoundException e)
e.printStackTrace();
TrafficInfo trafficInfo = new TrafficInfo();
trafficInfo.setName(name);
trafficInfo.setIcon(icon);
trafficInfo.setUid(uid);
trafficInfos.add(trafficInfo);
上面这个方法的注释已经很详细了,我就不多说啦,有什么不明白的,可以提出来
有了这个应用的列表之后,不用想的了,我们肯定会写一个adapter的了
private class TrafficAdapter extends BaseAdapter
@Override
public int getCount()
return trafficInfos.size();
@Override
public Object getItem(int position)
return trafficInfos.get(position);
@Override
public long getItemId(int position)
return position;
@Override
public View getView(int position, View convertView, ViewGroup parent)
View view;
ViewHolder holder;
TrafficInfo info = trafficInfos.get(position);
if(convertView == null)
view = View.inflate(TrafficManagerActivity.this, R.layout.traffic_manager_item, null);
holder = new ViewHolder();
holder.iv_traffic_icon = (ImageView) view.findViewById(R.id.iv_traffic_icon);
holder.tv_traffic_name = (TextView) view.findViewById(R.id.tv_traffic_name);
holder.tv_traffic_received = (TextView) view.findViewById(R.id.tv_traffic_received);
holder.tv_traffic_transmitted = (TextView) view.findViewById(R.id.tv_traffic_transmitted);
view.setTag(holder);
else
view = convertView;
holder = (ViewHolder) view.getTag();
holder.iv_traffic_icon.setImageDrawable(info.getIcon());
holder.tv_traffic_name.setText(info.getName());
//根据uid得到这个应用的接收数据大小
long received = TrafficStats.getUidRxBytes(info.getUid());
//根据uid得到这个应用的发送数据大小
long transmitted = TrafficStats.getUidTxBytes(info.getUid());
holder.tv_traffic_received.setText(TextFormater.dataSizeFormat(received));
holder.tv_traffic_transmitted.setText(TextFormater.dataSizeFormat(transmitted));
return view;
private class ViewHolder
ImageView iv_traffic_icon;
TextView tv_traffic_name;
TextView tv_traffic_received;
TextView tv_traffic_transmitted;
好啦,写到这里,我们的流量获取以及显示的操作,就基本上是完成的啦,但是还是有一点小问题要处理的,我们的流量是会变化的,但是我们这里根本就没有刷新机制,
所以,接下来,我们就用一个计时器来进行刷新的
@Override
protected void onStart()
timer = new Timer();
timerTask = new TimerTask()
@Override
public void run()
Message msg = Message.obtain();
handler.sendMessage(msg);
;
timer.schedule(timerTask, 1000, 3000);
super.onStart();
@Override
protected void onStop()
if(timer != null)
timer.cancel();
timer = null;
timerTask = null;
super.onStop();
我在onStart和onStop方法里面,进行了对一个计时器的初始化和取消,这样子,我们的流量列表就可以刷新的了,通过handler来刷新
@SuppressLint("HandlerLeak")
private Handler handler = new Handler()
public void handleMessage(Message msg)
adapter.notifyDataSetChanged();
;
好啦,这样子,流量管理的功能就读完的了,下面把完整的activity粘出来

好啦,今天就到这里,如果有什么不明白的,可以留言
注意,用模拟器来测试这个流量管理是会有点问题的,模拟器不支持一些功能的,所以最好用真机来测试
最后,和大家说一下
为了方便大家的交流,我创建了一个群,这样子大家有什么疑问也可以在群上交流
