Android GCM - "处理收到的数据"

Question

对于GCM Android文档在这里声明

数据参数中的键对值,它们在此意图中作为附加项提供,键是额外的名称.

private void handleMessage(Intent intent) {
    // server sent 2 key-value pairs, score and time
    String score = intent.getExtra("score");
    String time = intent.getExtra("time");
    // generates a system notification to display the score and time
}

但是intent.getExtra()方法不接受参数

public Bundle getExtras ()

Since: API Level 1
Retrieves a map of extended data from the intent.

Returns
the map of all extras previously added with putExtra(), or null if none have been added.

我的问题

如何从onMessage()方法中的GCM消息中检索"字符串" ？

PS onMessage(Context context, Intent intent): Called when your server sends a message to GCM, and GCM delivers it to the device. If the message has a payload, its contents are available as extras in the intent.

Answer 1

你应该使用:

intent.getExtras().getString("score");
intent.getExtras().getString("time");

注意类型,它可以是:

intent.getExtras().getInt("myvar");

或者其他一些类型.看看Bundle吧.
