 获取手机上已安装应用列表，将获取到的信息用集合返回，可以自己定义是否过滤系统应用，Appinfo是一个实体类，包含应用的名称 包名 图标icon等等

 /*** 获取手机已安装应用列表* @param ctx* @param isFilterSystem 是否过滤系统应用* @return*/public static ArrayList<AppInfo> getAllAppInfo(Context ctx,boolean isFilterSystem) {ArrayList<AppInfo> appBeanList = new ArrayList<>();AppInfo bean = null;PackageManager packageManager = ctx.getPackageManager();List<PackageInfo> list = packageManager.getInstalledPackages(0);for (PackageInfo p : list) {bean = new AppInfo();bean.setIcon(p.applicationInfo.loadIcon(packageManager));bean.setLabel(packageManager.getApplicationLabel(p.applicationInfo).toString());bean.setPackage_name(p.applicationInfo.packageName);int flags = p.applicationInfo.flags;// 判断是否是属于系统的apkif ((flags & ApplicationInfo.FLAG_SYSTEM) != 0&&isFilterSystem) {
//                bean.setSystem(true);} else {appBeanList.add(bean);}}return appBeanList;}

Appinfo

public class AppInfo {public int uid;public String label;//应用名称public String package_name;//应用包名public Drawable icon;//应用iconpublic AppInfo() {uid = 0;label = "";package_name = "";icon = null;}public int getUid() {return uid;}public void setUid(int uid) {this.uid = uid;}public String getLabel() {return label;}public void setLabel(String label) {this.label = label;}public String getPackage_name() {return package_name;}public void setPackage_name(String package_name) {this.package_name = package_name;}public Drawable getIcon() {return icon;}public void setIcon(Drawable icon) {this.icon = icon;}
