AppInfo.java 这是一个javabean
public class AppInfo {private Drawable icon;//图片的icon。Drawable适用的范围更广一点，可以是图片，也可以是xml等private String apkname;//程序的名字private long apksize;//程序的大小private boolean userApp;//表示是用户APP还是系统APP，true，用户APPprivate boolean isRom;//放置的位置private String apkPackageName;//包名
public Drawable getIcon() {return icon;}public void setIcon(Drawable icon) {this.icon = icon;}public String getApkname() {return apkname;}public void setApkname(String apkname) {this.apkname = apkname;}public long getApksize() {return apksize;}public void setApksize(long apksize) {this.apksize = apksize;}public boolean isUserApp() {return userApp;}public void setUserApp(boolean userApp) {this.userApp = userApp;}public boolean isRom() {return isRom;}public void setRom(boolean isRom) {this.isRom = isRom;}public String getApkPackageName() {return apkPackageName;}public void setApkPackageName(String apkPackageName) {this.apkPackageName = apkPackageName;}@Overridepublic String toString() {return "AppInfo [icon=" + icon + ", apkname=" + apkname + ", apksize=" + apksize + ", userApp=" + userApp+ ", isRom=" + isRom + ", apkPackageName=" + apkPackageName + "]";}}
AppInfos .java 获取当前手机上边所有的应用程序的详细信息public class AppInfos {public static List<AppInfo> getAppInfos(Context context){List<AppInfo> packageAppinfos = new ArrayList<AppInfo>();PackageManager pm=context.getPackageManager();//获取到包的管理者，即清单文件中的东西List<PackageInfo> installPackages = pm.getInstalledPackages(0);//获取安装到手机上边的安装包for(PackageInfo installPackage:installPackages){AppInfo appinfo = new AppInfo();//javabean//获取到应用程序的图标/名字/包名/资源路径Drawable drawable = installPackage.applicationInfo.loadIcon(pm);appinfo.setIcon(drawable);String apkName = installPackage.applicationInfo.loadLabel(pm).toString();appinfo.setApkname(apkName);String packageName = installPackage.packageName;appinfo.setApkPackageName(packageName);String sourceDir = installPackage.applicationInfo.sourceDir;File file = new File(sourceDir);//apk的长度long apksize = file.length();appinfo.setApksize(apksize); System.out.println(apkName+";"+packageName+";"+apksize);//第三方应用放在data/data/app 系统应用放在system/app//获取到安装应用程序的标记,都是二进制 int flags = installPackage.applicationInfo.flags;if((flags&ApplicationInfo.FLAG_SYSTEM)!=0){//系统应用appinfo.setUserApp(false);}else{//用户appappinfo.setUserApp(true);}if((flags&ApplicationInfo.FLAG_EXTERNAL_STORAGE)!=0){//sd卡appinfo.setRom(false);}else{//表示内存appinfo.setRom(true);}packageAppinfos.add(appinfo);}return packageAppinfos; }}

ViewUtils完全注解的方式进行UI绑定和事件绑定，无需findViewById()和 setClickListener().下面一篇博客来说明xUtils的使用。
