处理方法
按照下面的代码运行,就会获得已经安装的程序列表
1 2 3 | final Intent mainIntent = new Intent(Intent.ACTION_MAIN, null ); mainIntent.addCategory(Intent.CATEGORY_LAUNCHER); final List pkgAppsList = context.getPackageManager().queryIntentActivities( mainIntent, 0 ); |
或者下面链接和代码也

Here a good example:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | class PInfo { private String appname = "" ; private String pname = "" ; private String versionName = "" ; private int versionCode = 0 ; private Drawable icon; private void prettyPrint() { Log.v(appname + "\t" + pname + "\t" + versionName + "\t" + versionCode); } } private ArrayList<pinfo> getPackages() { ArrayList<pinfo> apps = getInstalledApps( false ); /* false = no system packages */ final int max = apps.size(); for ( int i= 0 ; i<max; arraylist<pinfo= "" private = "" }= "" apps;= "" return = "" apps.get(i).prettyprint();= "" {= "" i++)= "" > getInstalledApps( boolean getSysPackages) { ArrayList<pinfo> res = new ArrayList<pinfo>(); List<packageinfo> packs = getPackageManager().getInstalledPackages( 0 ); for ( int i= 0 ;i<packs.size();i++) }= "" return = "" {= "" pre= "" <= "" res;= "" res.add(newinfo);= "" newinfo.icon= "p.applicationInfo.loadIcon(getPackageManager());" newinfo.versioncode= "p.versionCode;" newinfo.versionname= "p.versionName;" newinfo.pname= "p.packageName;" newinfo.appname= "p.applicationInfo.loadLabel(getPackageManager()).toString();" pinfo();= "" newinfo= "new" pinfo= "" ;= "" continue = "" null ))= "" (p.versionname= "=" &&= "" ((!getsyspackages)= "" if = "" p= "packs.get(i);" packageinfo= "" ></packs.size();i++)></packageinfo></pinfo></pinfo></max;></pinfo></pinfo> |
