手机安全卫士——软件管理-用户程序和系统程序
首先看一下界面：

//也可以这样发消息
//Message obtain = Message.Obtain();
//handler.sendMessage(obtain); } }.start(); } private void initUI() { // TODO Auto-generated method stub setContentView(R.layout.activity_app_manager); ViewUtils.inject(this);//ViewUtils下文说明 lv = (ListView) findViewById(R.id.list_view); TextView tv_rom = (TextView) findViewById(R.id.tv_rom); TextView tv_sd = (TextView) findViewById(R.id.tv_sd); //得到ROM内存剩余空间，运行的大小 long rom_freeSpace = Environment.getDataDirectory().getFreeSpace(); //得到SD卡剩余空间，运行的大小 long sd_freeSpace = Environment.getExternalStorageDirectory().getFreeSpace(); //格式化大小 tv_rom.setText("内存可用："+Formatter.formatFileSize(this, rom_freeSpace)); tv_sd.setText("SD卡可用："+Formatter.formatFileSize(this, sd_freeSpace));

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APP private 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; } @Override public 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app appinfo.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。
