如何获取安装的Android应用程序的列表，并选择一个运行(How to get a list of installed android applications and pick one to run)

我本周早些时候提出了类似的问题，但是我仍然不了解如何获取所有已安装应用程序的列表，然后选择一个运行。

我试过了：

Intent intent = new Intent(ACTION_MAIN); intent.addCategory(CATEGORY_LAUNCHER);

并且这仅显示预安装的应用程序或可以运行ACTION_MAIN Intent类型。

我也知道我可以使用PackageManager来获取所有安装的应用程序，但是如何使用它来运行特定的应用程序？

I asked a similar question to this earlier this week but I'm still not understanding how to get a list of all installed applications and then pick one to run.

I've tried:

Intent intent = new Intent(ACTION_MAIN); intent.addCategory(CATEGORY_LAUNCHER);

and this only shows application that are preinstalled or can run the ACTION_MAIN Intent type.

I also know I can use PackageManager to get all the installed applications, but how do I use this to run a specific application?

以下是获取安装在Android上的活动/应用程序列表的代码：

Intent mainIntent = new Intent(Intent.ACTION_MAIN, null); mainIntent.addCategory(Intent.CATEGORY_LAUNCHER); List<ResolveInfo> pkgAppsList = context.getPackageManager().queryIntentActivities( mainIntent, 0);

您将获得ResolveInfo中的所有必需数据以启动应用程序。 您可以在这里检查ResolveInfo javadoc。

HTH！

Following is the code to get the list of activities/applications installed on Android :

Intent mainIntent = new Intent(Intent.ACTION_MAIN, null); mainIntent.addCategory(Intent.CATEGORY_LAUNCHER); List<ResolveInfo> pkgAppsList = context.getPackageManager().queryIntentActivities( mainIntent, 0);

You will get all the necessary data in the ResolveInfo to start a application. You can check ResolveInfo javadoc here.
