android如何获取正在运行的应用

可以使用ActivityManager类来获取正在运行的应用。以下是一个示例代码：

import android.app.ActivityManager;import android.content.Context;import android.content.pm.ApplicationInfo;import android.content.pm.PackageManager;import android.util.Log;import java.util.ArrayList;import java.util.List;public class RunningAppUtils {public static List<String> getRunningApps(Context context) {List<String> runningApps = new ArrayList<>();PackageManager packageManager = context.getPackageManager();ActivityManager activityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);List<ActivityManager.RunningAppProcessInfo> runningAppProcesses = activityManager.getRunningAppProcesses();for (ActivityManager.RunningAppProcessInfo processInfo : runningAppProcesses) {try {ApplicationInfo appInfo = packageManager.getApplicationInfo(processInfo.processName, PackageManager.GET_META_DATA);String appName = (String) packageManager.getApplicationLabel(appInfo);runningApps.add(appName);} catch (PackageManager.NameNotFoundException e) {Log.e("RunningAppUtils", "Failed to get app name for process: " + processInfo.processName);}}return runningApps;}}

你可以调用getRunningApps()方法来获取正在运行的应用的名称列表。
