Nexus 4屏幕奇怪

Question

I have this strange glitch on my Nexus4 screen when testing a very simple layout: just a linear layout with a TextView inside. Does anyone have an idea why and how to fix this bug ?

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          android:orientation="vertical"
          android:layout_width="match_parent"
          android:layout_height="match_parent">

<TextView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:textColor="@color/highlighted_text_material_light"
    android:id="@+id/measurement_tv"
    />
</LinearLayout>

This happens systematically when I use a simple layout but there is no problem for a more complicated layout

Answer 1

This may be a possible cause, but it is not programming related:

Is it possible that You have enabled HW Overlay. Sometimes it conflicts with rendering the layout. To disable or enable, go to:

settings-->developer options-->deactivate HW-Overlays

Had a similar problem, my screen looked like Yours and this was the cause.
