Question

我开始向我的应用添加通知，并希望它在通知抽屉中显示我的应用图标。问题是，图标非常小而且没有填满整个圆圈，它会在它周围留下浅蓝色（TouchWiz，我认为白色库存）边框。像WhatsApp这样的应用程序是如何让它填满整个圈子而不是调整大小？在状态栏中看起来很顺便。

我的代码显示通知：

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this)
                                                        .setSmallIcon(R.drawable.widget_icon)
                                                        .setContentTitle("My notification")
                                                        .setContentText("Hello World!");
        Intent resultIntent = new Intent(this, MainActivity.class);

        TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
        stackBuilder.addParentStack(MainActivity.class);
        stackBuilder.addNextIntent(resultIntent);

        PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);

        mBuilder.setContentIntent(resultPendingIntent);

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

        mNotificationManager.notify(1, mBuilder.build());

您可以致电public class NotificationIconDrawer { private Canvas mCanvas; private Bitmap mBmp; public NotificationIconDrawer() { mBmp = Bitmap.createBitmap(yourWidth, yourHeight, Config.RGB_565); mCanvas = new Canvas(mBmp); } public Bitmap draw() { mCanvas.drawBitmap(bitmap, matrix, paint); mCanvas.save(); return mBmp; }在nofication抽屉中设置图片

如果您对系统提供的图标大小不满意。你可以自己画画。简单的代码如下：
