如何检查我的活动是否是屏幕中正在运行的当前活动

import android.app.ActivityManager;
import android.content.ComponentName;
import android.content.Context;

public class ActivityUtils {
    public static boolean isCurrentActivity(Context context, Class<?> activityClass) {
        ActivityManager activityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
        ComponentName componentName = activityManager.getRunningTasks(1).get(0).topActivity;
        return componentName.getClassName().equals(activityClass.getName());
    }
}
