取得正在运行的服务

在main.xml中：

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout

xmlns:android="http://schemas.android.com/apk/res/android"

android:orientation="vertical"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

android:background="#3399ff">

<ListView

android:id="@+id/tasklist"

android:layout_gravity="center_horizontal"

android:layout_width="fill_parent"

android:layout_height="wrap_content" />

</LinearLayout>

在MyActivityRun.java中：

package com.li.activityrun;

import java.util.ArrayList;

import java.util.Iterator;

import java.util.List;

import android.app.Activity;

import android.app.ActivityManager;

import android.content.Context;

import android.os.Bundle;

import android.widget.ArrayAdapter;

import android.widget.ListAdapter;

import android.widget.ListView;

public class MyActivityRun extends Activity {

private ListView tasklist = null ;

private ListAdapter adapter = null ;

private List<String> all = new ArrayList<String>() ;

private ActivityManager activityManager = null ;

private List<ActivityManager.RunningServiceInfo> allTaskInfo ;

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

super.setContentView(R.layout.main);

this.tasklist = (ListView) super.findViewById(R.id.tasklist) ;

this.activityManager = (ActivityManager) super

.getSystemService(Context.ACTIVITY_SERVICE);

this.listActivity() ;

}

private void listActivity() {

this.allTaskInfo = this.activityManager.getRunningServices(30) ;

Iterator<ActivityManager.RunningServiceInfo> iterInfo = this.allTaskInfo.iterator() ;

while(iterInfo.hasNext()) {

ActivityManager.RunningServiceInfo service = iterInfo.next() ;

this.all.add("【ID = " + service.pid + " 】 "

+ service.process);

}

this.adapter = new ArrayAdapter<String>(this,

android.R.layout.易做图_list_item_1, this.all);

this.tasklist.setAdapter(this.adapter) ;

}

在AndroidManifest.xml中修改权限：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

package="com.li.activityrun"

android:versionCode="1"

android:versionName="1.0" >

<uses-sdk

android:minSdkVersion="8"

android:targetSdkVersion="15" />

<uses-permission android:name="android.permission.GET_TASKS"/>

<application

android:icon="@drawable/ic_launcher"

android:label="@string/app_name"

android:theme="@style/AppTheme" >

<activity

android:name=".MyActivityRun"

android:label="@string/title_activity_my_activity_run" >

<intent-filter>

</intent-filter>

</activity>

</application>

</manifest>
