2. In SystemUI/res/layout/quick_status_bar_expanded_header.xml add the lines (from +++ to +++):

<?xml version="1.0" encoding="utf-8"?>
<com.android.systemui.qs.QuickStatusBarHeader android:layout_gravity="@integer/notification_panel_layout_gravity" android:id="@id/header" android:clickable="false" android:clipChildren="false" android:clipToPadding="false" android:layout_width="fill_parent" android:layout_height="@dimen/status_bar_header_height" android:baselineAligned="false" android:importantForAccessibility="no"
xmlns:android="http://schemas.android.com/apk/res/android" xmlns:systemui="http://schemas.android.com/apk/res-auto">
<LinearLayout android:gravity="center" android:orientation="horizontal" android:id="@id/header_buttons_container" android:clipChildren="false" android:clipToPadding="false" android:layout_width="wrap_content" android:layout_height="@dimen/qs_quick_panel_item_height" android:layout_marginTop="@dimen/qs_quick_panel_item_top_margin" android:layout_marginEnd="@dimen/qs_quick_panel_settings_end_margin" android:layout_alignParentEnd="true">
+++ <mickles.app.statusbar.mLinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content" key="visibility_bat_temp" value="1">
<com.dev.Battery.BatteryTemperature android:textColor="#ffff0000" android:gravity="center_vertical" android:layout_width="wrap_content" android:layout_height="fill_parent" android:layout_alignParentEnd="true" />
</mickles.app.statusbar.mLinearLayout>+++
<mickles.app.statusbar.mLinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content" key="visibility_multi_user" value="1">
<com.android.systemui.statusbar.phone.MultiUserSwitch android:id="@id/multi_user_switch" android:background="@drawable/ripple_drawable" android:focusable="true" android:layout_width="@dimen/qs_quick_panel_button_width" android:layout_height="fill_parent" android:layout_alignParentEnd="true">
<ImageView android:layout_gravity="center" android:id="@id/multi_user_avatar" android:layout_width="@dimen/multi_user_avatar_expanded_size" android:layout_height="@dimen/multi_user_avatar_expanded_size" android:scaleType="centerInside" />
</com.android.systemui.statusbar.phone.MultiUserSwitch>
</mickles.app.statusbar.mLinearLayout>

Recompile SystemUI.apk

II. Rom Control

Add to right place:

<com.wubydax.romcontrol.v2.prefs.MySwitchPreference android:title="Battery Temperature" android:key="visibility_bat_temp" android:defaultValue="false" android:summaryOn="Show" android:summaryOff="Hide" />

The Color is red - #ffff0000 To change color change here - <com.dev.Battery.BatteryTemperature android:textColor="#ffff0000" android:gravity="center_vertical" android:layout_width="wrap_content" android:layout_height="fill_parent" android:layout_alignParentEnd="true" />

Without Rom Control:

Add to SystemUI/res/layout/quick_status_bar_expanded_header.xml this line <com.dev.Battery.BatteryTemperature android:textColor="#ffff0000" android:gravity="center_vertical" android:layout_width="wrap_content" android:layout_height="fill_parent" android:layout_alignParentEnd="true" /> only. This will be permanent view.
