上面有按钮Android的通知上面有按钮Android的通知(Android notificatio

2019-05-13 23:31发布

我试图做一个通知,上面有2个按钮:

  • 一个把我带回到活动
  • 其他关闭它

有没有人有关于如何捕捉到按钮单击事件的想法(记住,活动暂停)?

Answer 1:

我很高兴将它张贴! 工作了一整夜后,我发现了什么。 所以,在这里,我们走!

1.创建您的通知的XML布局文件。

2.创建使用Notification.Builder通知。 将一切后,你想要(图标,声音等),这样做:

        //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.创建一个方法setListeners。 在此方法中,你必须这样写:

    //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");</p>

    //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.对于我的要求我用它响应了主意,HelperActivity。 但对于你,我不认为这是必要的。

所有上述,回答捕事件从不同的按钮的问题。

关于取消通知我在这里您重定向

如何清除Android的通知

不过,别忘了使用您的通知方法解析的ID,当你要求拳头时间通知



Answer 2:

至于ICS,问题是简单的回复,因为所需的行为反映了默认的通知:您可以关闭通知其滑动到右侧,你可以定义用户发送当他按下它简单地使用到活动 PendingIntent

// The PendingIntent to launch our activity if the user selects this
// notification.  Note the use of FLAG_CANCEL_CURRENT so that, if there
// is already an active matching pending intent, cancel it and replace
// it with the new array of Intents.
PendingIntent contentIntent = PendingIntent.getActivities(this, 0,
        makeMessageIntentStack(this, from, message), PendingIntent.FLAG_CANCEL_CURRENT);

从代码中采取http://developer.android.com/guide/topics/ui/notifiers/notifications.html



Answer 3:

如果你想具体意图分配到一个按钮:

views.setOnClickPendingIntent(R.id.your_button_id, pendingIntent);

我想你只需要一个意向单击该按钮时发送,所以你必须避免设置的主要意图通知

notification.contentIntent = yourPendingIntent;

否则(如果设置“notification.contentIntent =的PendingIntent;”像往常一样)都意图将被称为这可能不是你想要什么/用户的期望。

如果你仍然想按通知的其他地方调用这个总的意图(或任何其他),你可以使用意向按次分配的方法与以上相同。 不要忘记设置

android:clickable="true"

任何视图你想跟踪的onClick()进行。

您可以通过它们在它们被调用活动额外跟踪这些意图。 如果打电话给你主/发射活动比你在这里追踪他们(因为它来自的javadoc此方法):

@Override
protected void onNewIntent(Intent intent) {
    super.onNewIntent(intent);
    Bundle data = intent.getExtras();

    if (data != null && data.containsKey(YOUR_INTENT_KEY_SOURCE_CONSTANT)) {
       // process your notification intent
    }

    // go on with smth else
}


Answer 4:

您可以在简单的添加动作按钮Notification设定行动的Notification.Builder和定义PendingIntent每个动作

下面是示例代码:

    NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.notification_icon)
                .setContentTitle("My notification")
                .setContentText("Hello World!")
       .addAction(R.drawable.action_posetive,"posetive",PendingIntent.getActivity(0,intent,0))
.addAction(R.drawable.action_clear,"clear",PendingIntent.getActivity(0,intent,0));
        NotificationManager mNotificationManager =
            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        mNotificationManager.notify(0, mBuilder.build());


Answer 5:

有你在这里一个完整的例子

    //Add this code to onCreate or some onclick Buttton
    NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    NotificationCompat.Builder builder = new NotificationCompat.Builder(getApplicationContext());
    long when = System.currentTimeMillis();
    builder.setSmallIcon(R.drawable.ic_notification);
    Intent notificationIntent = new Intent(getApplicationContext(), notificationActivity.class).putExtra("notification", "1");
    PendingIntent contentIntent = PendingIntent.getActivity(getApplicationContext(), 1, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
    builder.setContentIntent(contentIntent);
    Notification notification = builder.getNotification();
    notification.when = when;

    RemoteViews remoteViews = new RemoteViews(getApplicationContext().getPackageName(), R.layout.notification_view);
    remoteViews.setTextViewText(R.id.tvName, "New Name");
    listener(remoteViews,getApplicationContext());


    notification.contentView = remoteViews;
    notification.flags |= Notification.FLAG_AUTO_CANCEL;
    manager.notify(1, notification);

然后你就可以定义监听器的方法:

    public void listener(RemoteViews remoteViews, Context context) {
    // you have to make intetns for each action (your Buttons)
    Intent intent = new Intent("Accept");
    Intent intent2 = new Intent("Reject");

    PendingIntent pendingIntent = PendingIntent.getBroadcast(context,1,intent,0);
    PendingIntent pendingIntent2 = PendingIntent.getBroadcast(context,1,intent2,0);

    // add actions here !
    IntentFilter intentFilter = new IntentFilter();
    intentFilter.addAction("Accept");
    intentFilter.addAction("Reject");


    BroadcastReceiver receiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            if(intent.getAction().equals("Accept")){
                Toast.makeText(context, "Accepted !!", Toast.LENGTH_SHORT).show();
            } else if(intent.getAction().equals("Reject")) {
                Toast.makeText(context, "Rejected !!", Toast.LENGTH_SHORT).show();
            }
        }
    };

    context.registerReceiver(receiver,intentFilter);
    remoteViews.setOnClickPendingIntent(R.id.ivRequest,pendingIntent);
    remoteViews.setOnClickPendingIntent(R.id.ivReject,pendingIntent2);

}

这里是notification_view布局costumize您的通知。

    <?xml version="1.0" encoding="utf-8"?>
 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:padding="16dp">

<TextView
    android:id="@+id/textView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerVertical="true"
    android:text="Request from "
    />

<TextView
    android:id="@+id/tvName"
    android:layout_width="wrap_content"

    android:layout_toRightOf="@id/textView"
    android:text="Amin"
    />

<ImageView

    android:layout_width="30dp"
    android:layout_height="30dp"
    android:layout_alignParentEnd="true"

    android:src="@drawable/notification"
    />

<ImageView

    android:layout_width="30dp"
    android:layout_height="30dp"
    android:layout_marginEnd="10dp"
    android:layout_toLeftOf="@id/ivRequest"
    android:layout_centerVertical="true"
    android:src="@drawable/trash"
    />

  </RelativeLayout>


Answer 6:

对我来说,这是工作大大..我会记下整个例子。 这是创建的通知

public void createNotification2(String aMessage) {
    final int NOTIFY_ID = 11;
    String name = getString(R.string.app_name);
    String id = getString(R.string.app_name); // The user-visible name of the channel.
    String description = getString(R.string.app_name); // The user-visible description of the channel.
    NotificationCompat.Builder builder;
    if (notifManager == null) {
        notifManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
    }
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        int importance = NotificationManager.IMPORTANCE_HIGH;
        NotificationChannel mChannel = notifManager.getNotificationChannel(id);
        if (mChannel == null) {
            mChannel = new NotificationChannel(id, name, importance);
            mChannel.setDescription(description);
            mChannel.enableVibration(true);
            mChannel.setLightColor(getColor(R.color.colorPrimaryDark));
            mChannel.setVibrationPattern(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400});
            notifManager.createNotificationChannel(mChannel);
        }
    } else {

    }
    Intent Off_broadcastIntent = new Intent(this, Database_Update.class);
    Off_broadcastIntent.setAction("on");
    Off_broadcastIntent.putExtra("toastMessage", "1");
    PendingIntent Off_actionIntent = PendingIntent.getService(this, 0, Off_broadcastIntent, PendingIntent.FLAG_UPDATE_CURRENT);

    Intent on_broadcastIntent = new Intent(this, Database_Update.class);
    on_broadcastIntent.setAction("off");
    on_broadcastIntent.putExtra("toastMessage", "0");
    PendingIntent on_actionIntent = PendingIntent.getService(this, 0, on_broadcastIntent, PendingIntent.FLAG_UPDATE_CURRENT);

    Intent cancel_broadcastIntent = new Intent(this, Database_Update.class);
    cancel_broadcastIntent.setAction("cancel");
    cancel_broadcastIntent.putExtra("toastMessage", "close");
    PendingIntent cancel_actionIntent = PendingIntent.getService(this, 0, cancel_broadcastIntent, PendingIntent.FLAG_UPDATE_CURRENT);

    Intent content_intent = new Intent(this, Status_Page.class);
    content_intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, content_intent, PendingIntent.FLAG_UPDATE_CURRENT);


    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this, id)
            .setSmallIcon(android.R.drawable.ic_popup_reminder)
            .setContentTitle(name)
            .setPriority(NotificationCompat.PRIORITY_HIGH)
            .setContentIntent(pendingIntent)
            .setAutoCancel(false)
            .setVibrate(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400})
            .addAction(R.drawable.block, "ON", Off_actionIntent)
            .addAction(R.drawable.notification, "OFF", on_actionIntent)
            .addAction(R.drawable.clear, "CLOSE", cancel_actionIntent);
    Notification notification = mBuilder.build();
    notification.flags = Notification.FLAG_NO_CLEAR|Notification.FLAG_ONGOING_EVENT;
    notifManager.notify(11, notification);
}

在Android中Menifest

<service android:name=".Database_Update"></service>

这是服务类

public class Database_Update extends Service {
String result="";

Realm realm;
BlockList blockList;
@Override
public void onCreate() {
    try {
        RealmConfiguration config = new RealmConfiguration.Builder()
                .name("notification.realm")
                .schemaVersion(1)
                .deleteRealmIfMigrationNeeded()
                .build();
        realm = Realm.getInstance(config);

    } catch (Exception e) {

        Log.d("Error Line Number", Log.getStackTraceString(e));
    }
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    //Toast.makeText(this, "service starting", Toast.LENGTH_SHORT).show();
    Log.d("SERVICE","SERVICE CHECKING");
    result=intent.getStringExtra("toastMessage");
    Log.d("SERVICE",result);
    if (realm!=null){
        Log.d("SERVICE","realm working");
    }else {
        Log.d("SERVICE","Realm not working");
    }
    blockList=realm.where(BlockList.class).equalTo("package_name", "BLOCK_ALL").findFirst();
    try {
        Log.d("SERVICE",blockList.getStatus());
    } catch (Exception e) {
        Log.d("Error Line Number", Log.getStackTraceString(e));
    }
    realm.beginTransaction();
    if (result.equals("1")){
        if (blockList==null){
            BlockList blockList_new=realm.createObject(BlockList.class);
            blockList_new.setPackage_name("BLOCK_ALL");
            blockList_new.setStatus("yes");
        }else {
            blockList.setStatus("yes");
        }
        Log.d("SERVICE","BLOCKING NOTIFICATION");
        Toast.makeText(this, "BLOCKING", Toast.LENGTH_SHORT).show();
    }else if (result.equals("0")){
        if (blockList==null){
            BlockList blockList_new=realm.createObject(BlockList.class);
            blockList_new.setPackage_name("BLOCK_ALL");
            blockList_new.setStatus("no");
        }else {
            blockList.setStatus("no");
        }
        Log.d("SERVICE","ALLOW NOTIFICATION");
        Toast.makeText(this, "ALLOW NOTIFICATION", Toast.LENGTH_SHORT).show();
    }else if (result.equals("close")){
        NotificationManager manager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
        manager.cancel(11);
        Log.d("SERVICE","REMOVING");
        Toast.makeText(this, "CLOSED", Toast.LENGTH_SHORT).show();
    }
    realm.commitTransaction();
    return START_STICKY;
}

@Override
public IBinder onBind(Intent intent) {
    // We don't provide binding, so return null
    return null;
}

@Override
public void onDestroy() {
    if (realm!=null){
        realm.close();
    }
    Toast.makeText(this, "REMOVING", Toast.LENGTH_SHORT).show();
