事件OnClick用于自定义通知中的按钮

Question

我有一个带按钮的自定义通知.要设置通知并使用事件OnClick on my button,我使用了以下代码:

//Notification and intent of the notification 
Notification notification = new Notification(R.drawable.stat_notify_missed_call,
            "Custom Notification", System.currentTimeMillis());

Intent mainIntent = new Intent(getBaseContext(), NotificationActivity.class);
PendingIntent pendingMainIntent = PendingIntent.getActivity(getBaseContext(),
    0, mainIntent , 0);
notification.contentIntent = pendingMainIntent;

//Remoteview and intent for my button
RemoteViews notificationView = new RemoteViews(getBaseContext().getPackageName(),
    R.layout.remote_view_layout);

Intent activityIntent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:190"));
PendingIntent pendingLaunchIntent = PendingIntent.getActivity(getBaseContext(), 0,
            activityIntent, PendingIntent.FLAG_UPDATE_CURRENT);

notificationView.setOnClickPendingIntent(R.id.button1,
    pendingLaunchIntent);

notification.contentView = notificationView;

notificationManager.notify(CUSTOM_NOTIFICATION_ID, notification);

使用此代码,我使用自定义布局自定义通知...但我无法单击按钮!每次我尝试单击按钮时,我都会单击整个通知,因此脚本会启动"mainIntent"而不是"activityIntent".

我在互联网上看到这段代码不适用于所有终端.我已经在模拟器和HTC Magic上尝试过但我总是遇到同样的问题:我无法点击按钮!

我的代码是对的？有人可以帮帮我吗？

谢谢,

我正在我的MyActivity.java课程中编写扩展代码android.app.Activity

当用户点击它发送的按钮时,它会创建一个自定义通知broadcast.有一个广播接收器接收broadcast.

private void createDownloadNotification() {
        Intent closeButton = new Intent("Download_Cancelled");
        closeButton.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);

        PendingIntent pendingSwitchIntent = PendingIntent.getBroadcast(this, 0, closeButton, 0);

        RemoteViews notificationView = new RemoteViews(getPackageName(), R.layout.widget_update_notification);

        NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

        NotificationCompat.Builder builder = new NotificationCompat.Builder(this).setSmallIcon(R.drawable.ic_launcher).setTicker("Ticker Text").setContent(notificationView);
        notificationView.setProgressBar(R.id.pb_progress, 100, 12, false);
        notificationView.setOnClickPendingIntent(R.id.btn_close, pendingSwitchIntent);

        notificationManager.notify(1, builder.build());

    }


public static class DownloadCancelReceiver extends BroadcastReceiver {

        @Override
        public void onReceive(Context context, Intent intent) {

            System.out.println("Received Cancelled Event");
        }
    }

注册接收器 AndroidManifest.xml

<receiver android:name=".MainActivity$DownloadCancelReceiver" android:exported="false">
            <intent-filter>
                <action android:name="Download_Cancelled" />
            </intent-filter>
        </receiver>

因为它是内部类所以必须使用$标志

小部件xml在这里

<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:gravity="center"
    android:orientation="horizontal" >

    <Button
        android:id="@+id/btn_close"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Close Me" />

    <ProgressBar
        android:id="@+id/pb_progress"
        style="?android:attr/progressBarStyleHorizontal"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

</LinearLayout>

看一下这个

1. 为您的通知创建一个xml布局文件.

2. 使用Notification.Builder创建通知.添加所需内容(图标,声音等)后,执行以下操作:

   //R.layout.notification_layout is from step 1
   
   RemoteViews contentView=new RemoteViews(ctx.getPackageName(), R.layout.notification_layout);
   
   setListeners(contentView);//look at step 3
   
   notification.contentView = contentView;
   

3. 创建方法setListeners.在这个方法里面你必须写这个:

   //HelperActivity will be shown at step 4
   
   Intent radio=new Intent(ctx, packagename.youractivity.class);  
   radio.putExtra("AN_ACTION", "do");//if necessary
   
   PendingIntent pRadio = PendingIntent.getActivity(ctx, 0, radio, 0);
   //R.id.radio is a button from the layout which is created at step 2                  view.setOnClickPendingIntent(R.id.radio, pRadio); 
   
   //Follows exactly my code!
   Intent volume=new Intent(ctx, tsapalos11598712.bill3050.shortcuts.helper.HelperActivity.class);
   volume.putExtra("DO", "volume");
   
   //HERE is the whole trick. Look at pVolume. I used 1 instead of 0.
   PendingIntent pVolume = PendingIntent.getActivity(ctx, 1, volume, 0);
   view.setOnClickPendingIntent(R.id.volume, pVolume);
   

4. 根据我的要求,我使用了一个响应意图的HelperActivity.但对你来说,我认为没有必要.

如果你想要完整的源代码,你可以浏览它或从我的git repo下载它.该代码仅供个人使用,因此不要期望阅读带有大量注释的华丽代码.https://github.com/BILLyTheLiTTle/AndroidProject_Shortcuts

以上所有,回答了从不同按钮捕捉事件的问题.
