Obtain the list of applications running in android

Recently, I want to practice a task manager. The first question is to get a program running on the mobile phone. Later, I found some information on the Internet and finally got an eye on it. Not much nonsense! Check the code.

 

ActivityMain. java

Public class ActivityMain extends ListActivity {<br/> @ Override <br/> public void onCreate (Bundle savedInstanceState) {<br/> super. onCreate (savedInstanceState); <br/> requestWindowFeature (Window. FEATURE_INDETERMINATE_PROGRESS); </p> <p> List <Programe> list = getRunningProcess (); <br/> ListAdapter adapter = new ListAdapter (list, this ); <br/> getListView (). setAdapter (adapter); <br/>}</p> <p> // running <br /> Public List <Programe> getRunningProcess () {<br/> PackagesInfo pi = new PackagesInfo (this); </p> <p> ActivityManager am = (ActivityManager) getSystemService (ACTIVITY_SERVICE); <br/> // obtain the running application <br/> List <RunningAppProcessInfo> run = am. getRunningAppProcesses (); <br/> // obtain the Package Manager. The package name is used to obtain the program icon and program name. <br/> PackageManager pm = this. getPackageManager (); <br/> List <Programe> list = new ArrayList <Programe> (); </p> <P> for (RunningAppProcessInfo ra: run) {<br/> // This is mainly used to filter system applications and telephone applications. Of course, you can also comment out it. <Br/> if (ra. processName. equals ("system") | ra. processName. equals ("com. android. phone ") {<br/> continue; <br/>}</p> <p> Programe pr = new Programe (); <br/> pr. setIcon (pi. getInfo (ra. processName ). loadIcon (pm); <br/> pr. setName (pi. getInfo (ra. processName ). loadLabel (pm ). toString (); <br/> System. out. println (pi. getInfo (ra. processName ). loadLabel (pm ). toString (); <br/> list. add (pr); <br/>}< br/> return list; <br/>}</p> <p>} 

 

ListAdapter. java

Public class ListAdapter extends BaseAdapter {<br/> List <Programe> list = new ArrayList <Programe> (); <br/> LayoutInflater la; <br/> Context context; </p> <p> public ListAdapter (List <Programe> list, Context context) {<br/> this. list = list; <br/> this. context = context; <br/>}</p> <p> @ Override <br/> public int getCount () {<br/> // TODO Auto-generated method stub <br/> return list. size (); <br/>}< br/> @ Override <br/> public Object getItem (int position) {<br/> // TODO Auto-generated method stub <br/> return list. get (position); <br/>}< br/> @ Override <br/> public long getItemId (int position) {<br/> // TODO Auto-generated method stub <br/> return position; <br/>}< br/> @ Override <br/> public View getView (int position, View convertView, ViewGroup parent) {<br/> ViewHolder holder; <br/> if (convertView = null) <br/>{< br/> la = LayoutInflater. from (context); <br/> convertView = la. inflate (R. layout. list_item, null); </p> <p> holder = new ViewHolder (); <br/> holder. imgage = (ImageView) convertView. findViewById (R. id. image); <br/> holder. text = (TextView) convertView. findViewById (R. id. text); </p> <p> convertView. setTag (holder); <br/>}else {<br/> holder = (ViewHolder) convertView. getTag (); <br/>}< br/> final Programe pr = (Programe) list. get (position); <br/> // set the icon <br/> holder. imgage. setImageDrawable (pr. getIcon (); <br/> // set the program name <br/> holder. text. setText (pr. getName (); </p> <p> return convertView; <br/>}< br/> class ViewHolder {<br/> TextView text; <br/> ImageView imgage; <br/>} 

 

PackagesInfo. java

Public class PackagesInfo {<br/> private List <ApplicationInfo> appList; </p> <p> public PackagesInfo (Context context) {<br/> // Package Manager, retrieve all applications (or even uninstalled) and Data Directories <br/> PackageManager pm = context. getApplicationContext (). getPackageManager (); <br/> appList = pm. getInstalledApplications (PackageManager. GET_UNINSTALLED_PACKAGES); <br/>}</p> <p>/** <br/> * returns an Application Object of the program through a program name. <Br/> * @ param name <br/> * @ returnApplicationInfo <br/> */</p> <p> public ApplicationInfo getInfo (String name) {<br/> if (name = null) {<br/> return null; <br/>}< br/> for (ApplicationInfo appinfo: appList) {<br/> if (name. equals (appinfo. processName) {<br/> return appinfo; <br/>}< br/> return null; <br/>}</p> <p >}< br/> 

Programe. java

 

Public class Programe {<br/> // icon <br/> private Drawable icon; <br/> // program name <br/> private String name; </p> <p> public Drawable getIcon () {<br/> return icon; <br/>}< br/> public void setIcon (Drawable icon) {<br/> this. icon = icon; <br/>}< br/> public String getName () {<br/> return name; <br/>}< br/> public void setName (String name) {<br/> this. name = name; <br/>}</p> <p>} 

 

List_item.xml

<? Xml version = "1.0" encoding = "UTF-8"?> <Br/> <LinearLayout xmlns: android = "http://schemas.android.com/apk/res/android" <br/> android: orientation = "horizontal" <br/> android: layout_width = "wrap_content" <br/> android: layout_height = "wrap_content" <br/> <ImageView <br/> android: id = "@ + id/image" <br/> android: layout_width = "wrap_content" <br/> android: layout_height = "wrap_content" <br/> android: layout_marginRight = "10dip" <br/> <TextView <br/> android: id = "@ + id/text" <br/> android: layout_width = "wrap_content" <br/> android: layout_height = "wrap_content" <br/> </p> </LinearLayout>
