I have tried various solution from stack overflow with no luck. What I want.

我已经尝试了堆栈溢出的各种解决方案，没有运气。我想要的是。

1. I know package name of different applications.
2. 我知道不同应用程序的包名称。
3. I want to get application Icon from those package name.
4. 我想从这些包名中获取应用程序图标。
5. Show those icons in Image View.
6. 在图像视图中显示这些图标。

For example, I have a package name com.example.testnotification. How to get this apps icon and show it in an ImageView?

例如，我有一个包名com.example.testnotification。如何获取此应用程序图标并在ImageView中显示它？

if you want to get icon (picture) of any installed application from there packagename, then just copy and paste this code. it will work

如果你想从packagename获取任何已安装应用程序的图标（图片），那么只需复制并粘贴此代码即可。它会工作

try
{
    Drawable d = getPackageManager().getApplicationIcon("com.AdhamiPiranJhandukhel.com");
    my_imageView.setBackgroundDrawable(d);
}
catch (PackageManager.NameNotFoundException e)
{
    return;
}

这也有效：

try

    Drawable d = getPackageManager().getApplicationIcon(getApplicationInfo());
    my_imageView.setBackgroundDrawable(d);

catch (PackageManager.NameNotFoundException e)

}

    }
