向通知中的按钮添加 onClick 操作 [英] Adding onClick Action To Button In Notification

问题描述

我正在尝试使用自定义布局向通知添加按钮.我能够添加布局并显示按钮.但是，我仍然想不出将单击侦听器添加到按钮的方法.这是我拥有的相关代码:

I'm trying to add button to Notification using custom layout. I was able to add the layout and display the button. However, I still can't figure out a way to add click listener to the button. Here is the relevant code I have:

添加自定义布局通知的代码:

String ns = Context.NOTIFICATION_SERVICE;
mNotificationManager = (NotificationManager) ctx.getSystemService(ns);
CharSequence tickerText = "Quick Application Launcher";
long when = System.currentTimeMillis();
Notification.Builder builder = new Notification.Builder(ctx);
Notification notification=builder.getNotification();
notification.when=when;
notification.tickerText=tickerText;
notification.icon=R.drawable.ic_launcher;

RemoteViews contentView=new RemoteViews(ctx.getPackageName(), R.layout.custom_notification);

Intent volume=new Intent(ctx, NotifActivityHandler.class);
volume.putExtra("DO", "2");
PendingIntent pVolume = PendingIntent.getActivity(ctx, 1, volume, 0);
contentView.setOnClickPendingIntent(R.id.btn2, pVolume);

notification.contentView = contentView;
notification.flags |= Notification.FLAG_ONGOING_EVENT;
mNotificationManager.notify(2345345, notification);

这是 NotifActivityHandler 代码:

public class NotifActivityHandler extends Activity {

    private NotifActivityHandler ctx;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        ctx=this;
        String action= (String)getIntent().getExtras().get("DO");
        Log.i("LOG", "lauching action: " + action);
        if(action.equals("1")){
        } else if(action.equals("2")){
        } else if(action.equals("config")){
            Intent i = new Intent(NotifActivityHandler.this, ConfigActivity.class);
            startActivity(i);
        }
    }   
}

即使我输入了Log.i，上面的代码也不会产生任何日志.我不确定这有什么问题.任何帮助表示赞赏.

Codes above doesn't produce any log even if I put Log.i. I'm not sure what is wrong with this. Any help is appreciated.

更新

我在 ICS 设备上对此进行了测试.

您可能需要在 AndroidManifest.xml 中注册您的监听器.看看这个
