笔者最近在重构公司项目中的push模块，之前某个业务会同时推一条通知栏消息和一条透传消息，分别对应个推中onNotificationMessageArrived和onReceiveMessageData。然而当点击通知栏消息时，个推在触发onNotificationMessageClicked后默认又会执行onReceiveMessageData，导致还需要额外写代码去区分收到的是透传消息还是通知栏点击，十分蛋疼。本次重构修改为后端只推一条透传消息，由于个推的透传没有提供默认通知栏的方法，为保留之前的业务逻辑Android端需要在透传中创建Notification并绑定通知的点击事件。

要点

1.onReceivePassThroughMessage中处理原来的透传消息，并创建Notification
2.Notification的点击事件绑定静态广播，收到广播后执行通知栏点击方法
3.由于推送模块是个library需要从app工程中获取通知栏图标资源文件

新增代码

/**
 * 个推透传创建通知栏
 *
 * @param title
 * @param subtitle
 */
private void addNotification(String title, String subtitle, MixPushMessage message) {
    //显示不重复通知
    int requestCode = (int) System.currentTimeMillis();

    Intent broadcastIntent = new Intent(this, GeTuiNotificationClickReceiver.class);
    broadcastIntent.putExtra("message", message);
    PendingIntent pendingIntent = PendingIntent.
            getBroadcast(this, requestCode, broadcastIntent, PendingIntent.FLAG_UPDATE_CURRENT);

    Notification.Builder builder = new Notification.Builder(this);
    builder.setWhen(System.currentTimeMillis())
            .setContentTitle(title)
            .setContentText(subtitle)
            .setDefaults(Notification.DEFAULT_LIGHTS)
            //.setVibrate(new long[]{0, 300, 300, 300})
            //设置点击通知跳转页面后，通知消失
            .setAutoCancel(true)
            .setContentIntent(pendingIntent);
    //获取app工程中的图片资源
    int logoId = getApplicationContext().getResources().getIdentifier(getIconName(getApplicationContext()), "mipmap",
            getApplicationContext().getPackageName());
    builder.setSmallIcon(logoId);
    NotificationManager manager = (NotificationManager) getSystemService(getApplicationContext().NOTIFICATION_SERVICE);
    manager.notify(requestCode, builder.build());
}

上边的代码中值得一提的是pendingIntent 中的requestCode和notify()参数中的requestCode，前者用来区分是否是同一intent，如果写死的话只会取最新的intent，后者者对应通知的id，写死的话重复使用同一条通知栏通知。

/**
* 获取主工程mipmap下的资源文件名
*/
public static String getIconName(Context mContext) {
    String value = "";
    try {
        ApplicationInfo appInfo = mContext.getPackageManager().
                getApplicationInfo(mContext.getPackageName(), PackageManager.GET_META_DATA);
        value = appInfo.metaData.getString("OEM_ICON");
    } catch (PackageManager.NameNotFoundException e) {
        e.printStackTrace();
    }
    return value;
}



/**
* 静态广播接收器-通知栏点击
*/
public class GeTuiNotificationClickReceiver extends BroadcastReceiver {
    public GeTuiNotificationClickReceiver() {
    }

    @Override
    public void onReceive(Context context, Intent intent) {
        GeTuiManager.sMixMessageProvider.onNotificationMessageClicked(context, (MixPushMessage) intent.getSerializableExtra("message"));
    }
}

相关代码

public class GeTuiManager implements MixPushManager {

    public static MixMessageProvider sMixMessageProvider;

    @Override
    public String getPushName() {
        return PushChannel.getui.name();
    }

    @Override
    public void registerPush(Context context) {
        PushManager.getInstance().initialize(context, null);
        PushManager.getInstance().registerPushIntentService(context, GeTuiMessageIntentService.class);
    }

    @Override
    public void unRegisterPush(Context context) {
        PushManager.getInstance().stopService(context);
    }

    @Override
    public void setMessageProvider(MixMessageProvider provider) {
        sMixMessageProvider = provider;
    }
 }


public interface MixMessageProvider {
    /**
     * 透传
     */
    void onReceivePassThroughMessage(Context context, MixPushMessage message);

    /**
     * 通知栏消息点击
     */
    void onNotificationMessageClicked(Context context, MixPushMessage message);

    /**
     * 通知栏消息到达
     */
    void onNotificationMessageArrived(Context context, MixPushMessage message);

    /**
     * 客户端推送ID
     */
    void onReceiveClientId(Context context, MixPushMessage message);

}

最后不要忘了在AndroidManifest.xml中注册广播！

      <receiver
        android:name=".receiver.GeTuiNotificationClickReceiver"
        android:enabled="true"
        android:exported="false"/>
