如何在Android上使用通知中的新数据重新启动当前活动点击意向

// 创建通知
NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
        .setSmallIcon(R.drawable.notification_icon)
        .setContentTitle("新消息")
        .setContentText("您收到了一条新消息")
        .setAutoCancel(true);

// 创建启动活动的意图
Intent intent = new Intent(this, MainActivity.class);
intent.putExtra("newData", newData); // newData为通知中的新数据
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

// 设置通知的点击意图
builder.setContentIntent(pendingIntent);

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

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

    // 获取启动活动的意图
    Intent intent = getIntent();
    if (intent != null) {
        Bundle extras = intent.getExtras();
        if (extras != null && extras.containsKey("newData")) {
            String newData = extras.getString("newData");
            // 处理新数据
        }
    }
}

@Override
protected void onNewIntent(Intent intent) {
    super.onNewIntent(intent);
    setIntent(intent);
}
