【问题描述】：

我正在使用RemoteViews 创建自定义通知。有什么方法可以自定义通知区域特别高度......？？？我不想使用BigView 因为我需要将它用于小于 11 的 API。

截图是：

这是我的代码：

public class Main extends Activity 
    @Override
    protected void onCreate(Bundle savedInstanceState) 
        super.onCreate(savedInstanceState);
        setContentView(R.layout.notificationmain);

        Button bnotify = (Button) findViewById(R.id.notification);
        Button bcustomnotify = (Button) findViewById(R.id.customnotification);

        // Click For Default Notification       
        bnotify.setOnClickListener(new OnClickListener() 
            public void onClick(View arg0) 
                Notification();
            
        );

        // Click For Custom Notification
        bcustomnotify.setOnClickListener(new OnClickListener() 
            public void onClick(View arg0) 
                CustomNotification();
            
        );

    

    // Default Notification
    public void Notification() 
        String strtitle = getString(R.string.notificationtitle);
        String strtext = getString(R.string.notificationtext);
        Intent intent = new Intent(this, NotificationView.class);
        intent.putExtra("title", strtitle);
        intent.putExtra("text", strtext);

        PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent,
                PendingIntent.FLAG_UPDATE_CURRENT);

        NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.logosmall)
                .setTicker(getString(R.string.notificationticker))
                .setContentTitle(getString(R.string.notificationtitle))
                .setContentText(getString(R.string.notificationtext))
                .addAction(R.drawable.ic_launcher, "Action Button", pIntent)
                .setContentIntent(pIntent)
                .setAutoCancel(true);

        // Create Notification Manager
        NotificationManager notificationmanager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        notificationmanager.notify(0, builder.build());
    


    // Custom Notification

    public void CustomNotification() 
        // Using RemoteViews to bind custom layouts into Notification
        RemoteViews remoteViews = new RemoteViews(getPackageName(),
                R.layout.customnotification);

        String strtitle = getString(R.string.customnotificationtitle);
        String strtext = getString(R.string.customnotificationtext);

        Intent intent = new Intent(this, NotificationView.class);
        intent.putExtra("title", strtitle);
        intent.putExtra("text", strtext);

        PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent,
                PendingIntent.FLAG_UPDATE_CURRENT);

        NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.logosmall)
                .setTicker(getString(R.string.customnotificationticker))
                .setAutoCancel(true)
                .setContentIntent(pIntent)
                .setContent(remoteViews);

        remoteViews.setImageViewResource(R.id.imagenotileft,R.drawable.ic_launcher);
        remoteViews.setImageViewResource(R.id.imagenotiright,R.drawable.androidhappy);

        remoteViews.setTextViewText(R.id.title,getString(R.string.customnotificationtitle));
        remoteViews.setTextViewText(R.id.text,getString(R.string.customnotificationtext));

        Calendar cal = Calendar.getInstance();
        cal.getTime();
        SimpleDateFormat sdf = new SimpleDateFormat("hh:mm a");

        remoteViews.setTextViewText(R.id.time,sdf.format(cal.getTime()) );
        NotificationManager notificationmanager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        notificationmanager.notify(1, builder.build());
    

    @Override
    public boolean onCreateOptionsMenu(Menu menu) 
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    

【问题讨论】：

您可以通过修改布局customnotification来控制高度，并使用更小尺寸的图片。

我想增加高度...

自定义通知布局的可用高度取决于通知视图。普通视图布局仅限于64 dp，展开视图布局仅限于256 dp。

@JoelFernandes ，我在customnotification 布局中将图像帧大小增加到 80dp，但高度仍然相同......

【参考方案1】：

看起来 Android 支持库 v4 有一个支持这种东西的通知生成器：http://developer.android.com/reference/android/support/v4/app/NotificationCompat.InboxStyle.html

NotificationCompat.InboxStyle 似乎是 4.1 之前设备的 BigView 等效项。

这允许您创建一个包含最多五行文本的较大通知，这可能会满足您的需求。

 Notification noti = new Notification.Builder()
 .setContentTitle("5 New mails from " + sender.toString())
 .setContentText(subject)
 .setSmallIcon(R.drawable.new_mail)
 .setLargeIcon(aBitmap)
 .setStyle(new Notification.InboxStyle()
     .addLine(str1)
     .addLine(str2)
     .setSummaryText("+3 more"))
 .setContentTitle("")
 .build();

【讨论】：

我将这些行合并到我的代码中作为默认通知...但它不起作用...

经过多次尝试，我终于在您的帮助下弄清楚了...thnx

太棒了，很高兴听到它！
