如何在自定义通知中引用视图

Question

在下面发布的代码中,我创建了一个自定义布局的通知.通知的布局包含三个操作按钮.

我现在的问题是,我无法引用代码中的任何按钮,以便我可以根据单击的操作按钮导航到另一个活动.我想要做的Action button 1 是点击何时Activity 1显示,何时Action button 2单击然后Activity 2出现等等.

请告诉我如何在通知的自定义布局中引用视图？

代码:

public class MainActivity extends AppCompatActivity {

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

        // Using RemoteViews to bind custom layouts into Notification
        RemoteViews remoteViews = new RemoteViews(getPackageName(), R.layout.layout_notification);
        String notification_title = "Notification_Title";
        String notification_text = "Notification_Text";

        // Open NotificationView Class on Notification Click
        Intent intent = new Intent(this, NotificationReply.class);
        // Send data to NotificationView Class
        intent.putExtra("title", notification_title);
        intent.putExtra("text", notification_text);
        // Open NotificationView.java Activity
        PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent,PendingIntent.FLAG_UPDATE_CURRENT);

        NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
                // Set Icon
                .setSmallIcon(R.mipmap.ic_launcher)
                // Set Ticker Message
                .setTicker("Ticker")
                // Dismiss Notification
                .setAutoCancel(true)
                // Set PendingIntent into Notification
                .setContentIntent(pIntent)
                // Set RemoteViews into Notification
                .setContent(remoteViews);

        Intent intentAction1 = new Intent(this, ActAction1.class);
        PendingIntent pendingIntentActAction1 = PendingIntent.getBroadcast(this, 1,intentAction1, PendingIntent.FLAG_UPDATE_CURRENT);
        remoteViews.setOnClickPendingIntent(R.id.btn_action1, pendingIntentActAction1);

        Intent intentAction2 = new Intent(this, ActAction2.class);
        PendingIntent pendingIntentActAction2 = PendingIntent.getBroadcast(this, 2,intentAction2, PendingIntent.FLAG_UPDATE_CURRENT);
        remoteViews.setOnClickPendingIntent(R.id.btn_action2, pendingIntentActAction2);

        Intent intentAction3 = new Intent(this, ActAction3.class);
        PendingIntent pendingIntentActAction3 = PendingIntent.getBroadcast(this, 3,intentAction3, PendingIntent.FLAG_UPDATE_CURRENT);
        remoteViews.setPendingIntentTemplate(R.id.btn_action3, pendingIntentActAction3);

        // Create Notification Manager
        NotificationManager notificationmanager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

        // Build Notification with Notification Manager
        notificationmanager.notify(0, builder.build());
    }
}

你必须使用RemoteViews#setOnClickPendingIntent()API​​：

相当于调用setOnClickListener(android.view.View.OnClickListener)来启动提供的PendingIntent。

    Intent firstIntent = new Intent(context, FirstActivity.class);
    PendingIntent firstPendingIntent = PendingIntent.getBroadcast(this, 0, firstIntent, 0);

    RemoteViews notificationView = ...
    notificationView.setOnClickPendingIntent(R.id.first_button, firstPendingIntent);
