Android - How to get application name? (Not package name)
提问by AndroidDev
In my manifest I have:
在我的清单中，我有：
<application
android:name=".MyApp"
android:icon="@drawable/ic_launcher_icon"
android:label="@string/app_name"
android:debuggable="true">
How do I get the label element?
我如何获得标签元素？
Note: My code is running inside of someone else's, so I don't have access to @string/app_name
注意：我的代码在其他人的内部运行，所以我无权访问 @string/app_name

There's an easier way than the other answers that doesn't require you to name the resource explicitly or worry about exceptions with package names. It also works if you have used a string directly instead of a resource.
有一种比其他答案更简单的方法，它不需要您显式命名资源或担心包名称的异常。如果您直接使用字符串而不是资源，它也可以工作。
Just do:
做就是了：
public static String getApplicationName(Context context) {
ApplicationInfo applicationInfo = context.getApplicationInfo();
int stringId = applicationInfo.labelRes;
return stringId == 0 ? applicationInfo.nonLocalizedLabel.toString() : context.getString(stringId);
}
Hope this helps.
希望这可以帮助。

In light of the comment from Snicolas, I've modified the above so that it doesn't try to resolve the id if it is 0. Instead it uses, nonLocalizedLabelas a backoff. No need for wrapping in try/catch.
根据 Snicolas 的评论，我修改了上面的内容，如果它是 0，它就不会尝试解析 id。相反，它nonLocalizedLabel用作退避。无需在 try/catch 中包装。

If not mentioned in the strings.xml/hardcoded in AndroidManifest.xml for whatever reason like android:label="MyApp"
如果在 AndroidManifest.xml 中的 strings.xml/hardcoded 中未提及，无论出于何种原因，例如 android:label="MyApp"
public String getAppLable(Context context) {
PackageManager packageManager = context.getPackageManager();
ApplicationInfo applicationInfo = null;
try {
applicationInfo = packageManager.getApplicationInfo(context.getApplicationInfo().packageName, 0);
} catch (final NameNotFoundException e) {
}
return (String) (applicationInfo != null ? packageManager.getApplicationLabel(applicationInfo) : "Unknown");
}
Or if you know the String resource ID then you can directly get it via
或者，如果您知道 String 资源 ID，则可以直接通过
getString(R.string.appNameID);

public static String getApplicationName(Context context) {
return context.getApplicationInfo().loadLabel(context.getPackageManager());
}

From any Context use:
从任何上下文使用：
getApplicationInfo().loadLabel(getPackageManager()).toString();

If you know Package name then Use following snippet
如果您知道包名称，则使用以下代码段
ApplicationInfo ai;
try {
ai = pm.getApplicationInfo(packageName, 0);
} catch (final NameNotFoundException e) {
ai = null;
}
final String applicationName = (String) (ai != null ? pm.getApplicationLabel(ai) : "(unknown)");
回答by Pir Fahim Shah
If you need only the application name, not the package name, then just write this code.
如果您只需要应用程序名称，而不需要包名称，那么只需编写此代码。
String app_name = packageInfo.applicationInfo.loadLabel(getPackageManager()).toString();

In Kotlin, use the following codes to get Application Name:
在Kotlin 中，使用以下代码获取应用程序名称：
// Get App Name
var appName: String = ""
val applicationInfo = this.getApplicationInfo()
val stringId = applicationInfo.labelRes
if (stringId == 0) {
appName = applicationInfo.nonLocalizedLabel.toString()
}
else {
appName = this.getString(stringId)
}

Get Appliction Name Using RunningAppProcessInfo as:
使用 RunningAppProcessInfo 获取应用程序名称：
ActivityManager am = (ActivityManager)this.getSystemService(ACTIVITY_SERVICE);
List l = am.getRunningAppProcesses();
Iterator i = l.iterator();
PackageManager pm = this.getPackageManager();
while(i.hasNext()) {
ActivityManager.RunningAppProcessInfo info = (ActivityManager.RunningAppProcessInfo)(i.next());
try {
CharSequence c = pm.getApplicationLabel(pm.getApplicationInfo(info.processName, PackageManager.GET_META_DATA));
Log.w("LABEL", c.toString());
}catch(Exception e) {
//Name Not FOund Exception
}
}

Okay guys another sleek option is
好吧，伙计们，另一个时尚的选择是
Application.Context.ApplicationInfo.NonLocalizedLabel
Application.Context.ApplicationInfo.NonLocalizedLabel
verified for hard coded android label on application element.
已验证应用程序元素上的硬编码 android 标签。
<application android:label="Big App"></application>
<application android:label="Big App"></application>
