如何在android中获取应用程序的名称？

Question

我想得到我的申请名称.我怎么能得到它？提前致谢.

Answer 1

用这个

String applicationName = getResources().getString(R.string.app_name);

参考: 资源类型

Answer 2

您可以使用PackageManager类来获取ApplicationInfo：

final PackageManager pm = context.getPackageManager();
ApplicationInfo ai;
try {
    ai = pm.getApplicationInfo(packageName, 0);
} catch (final NameNotFoundException e) {
    ai = null;
}
final String applicationName = (String) (ai != null ? pm.getApplicationLabel(ai) : "(unknown)");

编辑：CharSequence c = pm.getApplicationLabel(pm.getApplicationInfo(info.processName,PackageManager.GET_META_DATA));

这个会return the application name as defined in <application> tag of its manifest。

Answer 3

您可以使用 PackageManager#getApplicationInfo()

用于获取设备中安装的所有软件包的应用程序名称。假设您有当前的 Context 对象 ctx

Resources appR = ctx.getResources();
CharSequence txt = appR.getText(appR.getIdentifier("app_name",
"string", ctx.getPackageName()));
