试图获取包版本信息以在& quot;关于""信息 [英] Trying to get Package Version Information to display in an "About" message

问题描述

我一直在努力从PackageInfo对象类型获取正在运行的应用程序的versionName.

I have been struggling with getting the versionName for a running application from the PackageInfo Object type.

我已经构造了一个Parcelable接口，其中包含与PackageInfo Object类型相关的所有字段.该接口方法的主要输入是一个Parcel对象.

I have constructed a Parcelable Interface with all of the fields associated with the PackageInfo Object type. The primary input for that interface method is a Parcel object.

我似乎无法弄清楚如何正确关联这些Parcelable，Parcel和PackageInfo对象.

I cannot seem to figure out how to correctly associate these Parcelable, Parcel, and PackageInfo objects.

有没有我可以看的示例代码?似乎没有那么困难，但似乎让我很沮丧.

Is there any sample code out there that I can look at? Doesn't seem like it should be that difficult but it seems to be stumping me.

谢谢爵士

推荐答案

示例代码:

try {
    PackageInfo packageInfo = getPackageManager().getPackageInfo(getPackageName(), 0);
    return packageInfo.versionName;
} catch (NameNotFoundException e) {
    //Handle exception
}
