TextView background transparent, but expecting solid color

Question

In situation below, TextView background should be solid color, but instead i get it transparent somehow.. so on listview scroll, listview content is visible through textview, but it should not.

Here is my layout:

<FrameLayout 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="wrap_content"
    android:layout_gravity="top"
    android:id="@+id/listSection"
    android:textSize="19sp"
    android:textColor="@android:color/black"
    android:text="Medium Text"
    android:background="#707e89"
    android:padding="5dp"
    android:textStyle="bold"
    android:autoText="true" />

<ListView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/medicationList"
    android:layout_gravity="center_horizontal|top" />
</FrameLayout>

What is wrong here :) ?

Try swapping the two items in your FrameLayout. I suspect that the ListView is in fact transparent, and your TextView is under it.

Some more information is available from this SO question: Placing/Overlapping(z-index) a view above another view in android

Yes, that was the issue. I realized it by myself later, but still we can debate about the subject. "z-index is defined by the order in which the items are added". So, if TextView is added first, then it should be shown above all other components? – bajicdusko Feb 17 '14 at 07:08
The last item in the layout is the highest item and vice versa for the first item. Not a whole lot of debate required :) – NasaGeek Feb 17 '14 at 15:06

I guess the problem with the color you used for background.

<TextView
   android:background="#AARRGGBB" />

Above AA is for alpha channel, RR for red, GG for green and BB for blue. Here is the Hex Opacity Values that you can used for AA:

100% — FF 95% — F2 90% — E6 85% — D9 80% — CC 75% — BF 70% — B3 65% — A6 60% — 99 55% — 8C 50% — 80 45% — 73 40% — 66 35% — 59 30% — 4D 25% — 40 20% — 33 15% — 26 10% — 1A 5% — 0D 0% — 00

Try to change the color according to given format and see still the problem is happening there.

That was the first thing i've tried, but if you think about it little longer, "#707e89" is solid color, without transparency included, so you cant make it less transparent as it is now :). See discussion on anwser above (@NasaGeek). — bajicdusko, Feb 17 '14 at 07:11
