If you just want to list them from the command line you can use
如果您只想从命令行列出它们，您可以使用
aapt dump xmltree <apk-file> AndroidManifest.xml
The format is a bit perplexing at first, but all the info is there.
格式起初有点令人困惑，但所有信息都在那里。
You need the Android SDK installed to do this, of course.
当然，您需要安装 Android SDK 才能执行此操作。

You can use the PackageManager method getPackageArchiveInfoto retrieve the information from an APK file. Assuming your APK lives in the root of your SD card, you can use this code:
您可以使用 PackageManager 方法getPackageArchiveInfo从 APK 文件中检索信息。假设您的 APK 位于 SD 卡的根目录中，您可以使用以下代码：
String apkPath = Environment.getExternalStorageDirectory().getAbsolutePath()
+ "/MyApp.apk";
PackageManager pm = getPackageManager();
PackageInfo info = pm.getPackageArchiveInfo(apkPath,
PackageManager.GET_ACTIVITIES);
//Log.i("ActivityInfo", "Package name is " + info.packageName);
for (android.content.pm.ActivityInfo a : info.activities) {
Log.i("ActivityInfo", a.name);
}
There is plenty of additional information you can find in the ActivityInfo and PackageInfo objects.
您可以在 ActivityInfo 和 PackageInfo 对象中找到大量附加信息。

其实不用得到apk的路径，直接在activity内调用
其实不用得到apk的路径，直接在活动内调用
(English translation) You don't have to use the full path to the APK, just call the following directly from inside an Activity.
（英文翻译）您不必使用 APK 的完整路径，只需直接从 Activity 内部调用以下内容即可。
PackageManager manager = getPackageManager();
PackageInfo packageInfo = manager.getPackageInfo("your package name", PackageManager.GET_UNINSTALLED_PACKAGES);
