Android状态栏/通知栏图标白底问题

状态栏会显示一个白底的方框；下拉通知栏展开时的图标为白底方框加圆框，不展开时为黑底方框。

vendor/mediatek/proprietary/packages/apps/SystemUI/src/com/android/systemui/statusbar/phone/NotificationIconAreaController.java

private void updateTintForIcon(StatusBarIconView v, int tint) {
        boolean isPreL = Boolean.TRUE.equals(v.getTag(R.id.icon_is_pre_L));
        int color = StatusBarIconView.NO_COLOR;

     //*/not replace color，def no color

boolean colorize = false；

/*/
        boolean colorize = !isPreL || NotificationUtils.isGrayscale(v, mContrastColorUtil);

//*/
        if (colorize) {
            color = DarkIconDispatcher.getTint(mTintArea, v, tint);
        }
        v.setStaticDrawableColor(color);
        v.setDecorColor(tint);
    }

frameworks/base/core/java/android/app/Notification.java

private void processSmallIconColor(Icon smallIcon, RemoteViews contentView,
                StandardTemplateParams p) {

//*/def use no color

boolean colorable =  false;

/*/
            boolean colorable = !isLegacy() || getColorUtil().isGrayscaleIcon(mContext, smallIcon);

//*/
            int color;
            if (isColorized(p)) {
                color = getPrimaryTextColor(p);
            } else {
                color = resolveContrastColor(p);
            }
            if (colorable) {
                contentView.setDrawableTint(R.id.icon, false, color,
                        PorterDuff.Mode.SRC_ATOP);

            }
            contentView.setInt(R.id.notification_header, "setOriginalIconColor",
                    colorable ? color : NotificationHeaderView.NO_COLOR);
        }
 

单独应用通知设置：

NotificationManager notificationManager= (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        NotificationCompat.Builder builder=new NotificationCompat.Builder(this);
        Notification notification=builder.setContentTitle(getString(R.string.notification_title))
                .setContentText(getString(R.string.notification_content)).setWhen(System.currentTimeMillis())
                .setDefaults(Notification.DEFAULT_LIGHTS).setSmallIcon(R.mipmap.icon_weixin)
                .setColor(Color.parseColor("#880000FF"))
                .setLargeIcon(BitmapFactory.decodeResource(getResources(),R.mipmap.weixin_raw))
                .setContentIntent(PendingIntent.getActivities(this,0x0001,new Intent[]{new Intent(this,MainActivity.class)},PendingIntent.FLAG_UPDATE_CURRENT))
                .build();

        notificationManager.notify(1,notification);

 

大图标是应用logo图标；

小图标背景色要透明，然后用纯白勾勒出你需要的图标（用任意颜色都会表现为白色）。
