嗨，我正在创建一个应用程序，该应用程序将检测是否已截取屏幕截图，然后检索该特定屏幕截图。所以我已经能够检测到是否截取了屏幕截图。

但我想知道如何才能获得刚刚检测到的屏幕截图？

这是我的主要活动：

public static File sdDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
public static File f = new File(sdDir, "Screenshots/");
public static String paths = f.getPath();

  @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    context = getApplicationContext();

   directoryFileObserver = new DirectoryFileObserver(paths);
    directoryFileObserver.startWatching();
}

这是我的 File Observer 类：

public class DirectoryFileObserver extends FileObserver {

public DirectoryFileObserver(String path) {
    super(path,FileObserver.CREATE);
    paths = path;
}
@Override
public void onEvent(int event, String path) {
    if(path != null){
        NotificationCompat.Builder builder = (NotificationCompat.Builder) new NotificationCompat.Builder(context)
                        .setSmallIcon(R.mipmap.ic_launcher)
                        .setContentTitle("SCREENSHOT DETECTED")
                        .setContentText("YOU CREATED A NEW SCREENSHOT");

        // Add as notification
        NotificationManager manager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        manager.notify(0, builder.build());
    }
}
}

在此先感谢您提出任何建议，为我指明正确的方向或提供帮助！:D
