Android 带按钮的remoteViews，点击按钮时，通知栏无法收起答案

【问题标题】：Android remoteViews with buttons , when click the button, the notification bar can not pack upAndroid 带按钮的remoteViews，点击按钮时，通知栏无法收起

【问题描述】：

我用remoteviews自定义了notification，视图包含布局和两个按钮，我想要的是当用户单击名为“contentLayout”的布局时，将打开“测试”活动，并且当用户单击按钮“remindTenMinButton”或“remindLaterButton”时，将启动“Test2”操作。现在问题是“Test”活动正确启动，但对于“Test2”活动，当我单击通知栏中的按钮时，似乎什么也没发生，但是当我点击“返回”时，当通知栏向后折叠时，我可以看到Test2已经开始，所以问题是当用户点击按钮时如何让通知栏向后折叠远程视图？以下是我的代码：

MainActivity：

package com.example.androidtest2;
import android.app.Activity;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.app.TaskStackBuilder;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.support.v4.app.NotificationCompat;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.RemoteViews;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Button button = (Button) findViewById(R.id.button1);
    button.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

            NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
                    MainActivity.this).setSmallIcon(R.drawable.ic_launcher);

            String notifyTitle = "title....";

            String notifyContent = "content......";

            RemoteViews remoteViews = new RemoteViews(MainActivity.this
                    .getPackageName(), R.layout.notification_bar);
            remoteViews.setTextViewText(R.id.title, notifyTitle);
            remoteViews.setTextViewText(R.id.content, notifyContent);

            Intent resultIntent = new Intent(MainActivity.this, Test.class);

            TaskStackBuilder stackBuilder = TaskStackBuilder
                    .create(MainActivity.this);
            stackBuilder.addParentStack(Test.class);
            stackBuilder.addNextIntent(resultIntent);
            PendingIntent resultPendingIntent = stackBuilder
                    .getPendingIntent(0, PendingIntent.FLAG_CANCEL_CURRENT);

            Intent notifyLaterIntent = new Intent(MainActivity.this,
                    NotificationProcesssingReceiver.class);
            PendingIntent PendingNotifyLaterIntent = PendingIntent
                    .getBroadcast(MainActivity.this, 0, notifyLaterIntent,
                            PendingIntent.FLAG_CANCEL_CURRENT
                                    | PendingIntent.FLAG_ONE_SHOT);

            Intent notify10LaterIntent = new Intent(MainActivity.this,
                    NotificationProcesssingReceiver.class);
            PendingIntent PendingNotify10LaterIntent = PendingIntent
                    .getBroadcast(MainActivity.this, 0,
                            notify10LaterIntent, 0);

            remoteViews.setOnClickPendingIntent(R.id.contentLayout,
                    resultPendingIntent);
            remoteViews.setOnClickPendingIntent(R.id.remindLaterButton,
                    PendingNotifyLaterIntent);
            remoteViews.setOnClickPendingIntent(R.id.remindTenMinButton,
                    PendingNotify10LaterIntent);

            NotificationManager mNotificationManager = (NotificationManager) MainActivity.this
                    .getSystemService(Context.NOTIFICATION_SERVICE);

            Notification notification = mBuilder.build();
            notification.defaults = Notification.DEFAULT_SOUND;
            notification.audioStreamType = android.media.AudioManager.ADJUST_LOWER;

            notification.icon = R.drawable.ic_launcher;

            notification.tickerText = "ticker text...";

            notification.bigContentView = remoteViews;

            // mId allows you to update the notification later on.
            mNotificationManager.notify(1, notification);

        }
    });
}
}

NotificationProcesssingReceiver：

package com.example.androidtest2;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;

public class NotificationProcesssingReceiver extends BroadcastReceiver{
 @Override
    public void onReceive(Context context, Intent intent) 
    {
        Intent test = new Intent(context, Test2.class);
        test.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        //context.startActivity(toMainScreen);
        context.startActivity(test);
    }
}

测试：

public class Test extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_test);
    /* NotificationManager mNotificationManager = (NotificationManager)    getSystemService(Context.NOTIFICATION_SERVICE);
     mNotificationManager.cancel(1);*/

}

}

测试2：

    public class Test2 extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_test2);
}

}
