在android中点击通知检测应用程序是否正在运行

// 创建通知
NotificationCompat.Builder builder = new NotificationCompat.Builder(context)
        .setSmallIcon(R.drawable.notification_icon)
        .setContentTitle("应用程序运行状态检测")
        .setContentText("点击通知检测应用程序是否正在运行");

// 设置通知点击事件
Intent intent = new Intent(context, MainActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
builder.setContentIntent(pendingIntent);

// 发送通知
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, builder.build());

// 点击通知时触发的操作
pendingIntent.setOnClickPendingIntent(R.id.notification_layout, new PendingIntent.OnClickListener() {
    @Override
    public void onClick(View v) {
        // 获取当前运行的进程列表
        ActivityManager activityManager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
        List<ActivityManager.RunningAppProcessInfo> runningProcesses = activityManager.getRunningAppProcesses();

        // 检查是否存在目标应用程序的进程
        boolean isAppRunning = false;
        String targetPackageName = "com.example.myapp"; // 目标应用程序的包名
        for (ActivityManager.RunningAppProcessInfo processInfo : runningProcesses) {
            if (processInfo.processName.equals(targetPackageName)) {
                isAppRunning = true;
                break;
            }
        }

        // 根据应用程序是否正在运行给出相应的提示
        if (isAppRunning) {
            Toast.makeText(context, "应用程序正在运行", Toast.LENGTH_SHORT).show();
        } else {
            Toast.makeText(context, "应用程序已关闭或处于后台运行", Toast.LENGTH_SHORT).show();
        }
    }
});
