首先看一下界面:

AppManagerActivity .java
//软件管理
public class AppManagerActivity extends Activity implements View.OnClickListener{
    List<AppInfo> appinfos;
    ListView lv;
    
    private List<AppInfo> userAppInfos;

        initUI();
        initData();                
    }
     @Override
        public void onClick(View v) {
            switch (v.getId()) {
                //分享
                case R.id.ll_share:

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;
