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类中编写代码来扩展android.app.Activity
它会创建一个自定义通知，当用户单击它发送broadcast的按钮时。有一个接收broadcast的广播接收器。
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");
}
}
在AndroidManifest.xml注册接收器
<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
//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;
//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);

以上所有，回答了从不同按钮捕捉事件的问题。
关于取消通知我在这里重定向你（How to clear a notification in Android）。只需记住在第一次调用通知时使用您在notify方法中解析的ID
似乎setOnClickPendingIntent在内部集合中使用时不起作用。
因此，请尝试使用setPendingIntentTemplate而不是setOnClickPendingIntent。有关更多信息，请关注android开发者链接...
似乎setOnClickPendingIntent在内部集合中使用时不起作用：
请尝试使用setPendingIntentTemplate。
您需要创建服务以检测Click事件：例如，创建NotificationIntentService.class并将代码放在下面：
public class NotificationIntentService extends IntentService {
/**
* Creates an IntentService. Invoked by your subclass's constructor.
*/
public NotificationIntentService() {
super("notificationIntentService");
}
@Override
protected void onHandleIntent(Intent intent) {
switch (intent.getAction()) {
case "left":
android.os.Handler leftHandler = new android.os.Handler(Looper.getMainLooper());
leftHandler.post(new Runnable() {
@Override
public void run() {
Toast.makeText(getBaseContext(),
"You clicked the left button", Toast.LENGTH_LONG).show();
}
});
break;
case "right":
android.os.Handler rightHandler = new android.os.Handler(Looper.getMainLooper());
rightHandler.post(new Runnable() {
@Override
public void run() {
Toast.makeText(getBaseContext(), "You clicked the right button", Toast.LENGTH_LONG).show();
}
});
break;
}
}
}
将此方法添加到您的活动中：
private void sendNotification() {
RemoteViews expandedView = new RemoteViews(getPackageName(), R.layout.view_expanded_notification);
expandedView.setTextViewText(R.id.timestamp, DateUtils.formatDateTime(this, System.currentTimeMillis(), DateUtils.FORMAT_SHOW_TIME));
expandedView.setTextViewText(R.id.notification_message, mEditText.getText());
// adding action to left button
Intent leftIntent = new Intent(this, NotificationIntentService.class);
leftIntent.setAction("left");
expandedView.setOnClickPendingIntent(R.id.left_button, PendingIntent.getService(this, 0, leftIntent, PendingIntent.FLAG_UPDATE_CURRENT));
// adding action to right button
Intent rightIntent = new Intent(this, NotificationIntentService.class);
rightIntent.setAction("right");
expandedView.setOnClickPendingIntent(R.id.right_button, PendingIntent.getService(this, 1, rightIntent, PendingIntent.FLAG_UPDATE_CURRENT));
RemoteViews collapsedView = new RemoteViews(getPackageName(), R.layout.view_collapsed_notification);
collapsedView.setTextViewText(R.id.timestamp, DateUtils.formatDateTime(this, System.currentTimeMillis(), DateUtils.FORMAT_SHOW_TIME));
NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
// these are the three things a NotificationCompat.Builder object requires at a minimum
.setSmallIcon(R.drawable.ic_pawprint)
.setContentTitle(NOTIFICATION_TITLE)
.setContentText(CONTENT_TEXT)
// notification will be dismissed when tapped
.setAutoCancel(true)
// tapping notification will open MainActivity
.setContentIntent(PendingIntent.getActivity(this, 0, new Intent(this, MainActivity.class), 0))
// setting the custom collapsed and expanded views
.setCustomContentView(collapsedView)
.setCustomBigContentView(expandedView)
// setting style to DecoratedCustomViewStyle() is necessary for custom views to display
.setStyle(new android.support.v7.app.NotificationCompat.DecoratedCustomViewStyle());
// retrieves android.app.NotificationManager
NotificationManager notificationManager = (android.app.NotificationManager) getSystemService(NOTIFICATION_SERVICE);
notificationManager.notify(0, builder.build());
}
