Gradient styles

Question

In my Android application, I hid the default title bar, introduced TabView, and added my own title under the TabView tabs. At the moment I am using the android: attr / windowTitleStyle style, which makes my new title gray and gradient. It looks good, but my screens look pretty grayscale. I would like to tweak things a bit by making this title a different color gradient.

What am I watching here? Creating your own image and using it? Style? Android: attr / windowTitleStyle seems to expand depending on the height of your custom title; so I'm not sure if this is actually a single image.

I tried to execute LinearLayout on it with a bit of transparency (for example: creating color # 800000FF), but the gradient style that I have behind this LinearLayout disappears.

thanks for the help

Update:

In my answer below, I realized that I can create an XML file that defines the gradient and use it. It works fine inside the LinearLayout (titlebar_gradient), which I have on my layout. However, it does not work with external LinearLayout (background_gradient). Can someone tell me why? As I understand it, ListView should be transparent ...

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@drawable/background_gradient" > <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="47dip" android:background="@drawable/titlebar_gradient" android:gravity="center"> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="1" android:text="Item" style="?android:attr/windowTitleStyle" android:paddingLeft="5dip" android:maxLines="1" android:ellipsize="end" /> </LinearLayout> <ListView android:id="@+id/android:list" android:layout_width="fill_parent" android:layout_height="fill_parent" android:paddingTop="10dip" android:clickable="false" /> <TextView android:id="@+id/android:empty" android:layout_width="fill_parent" android:layout_height="fill_parent" /> </LinearLayout> 

Answer 1

Yes, I also saw an example for providing gradient colors for linelayout or for a button on this site http://android-codes-examples.blogspot.com/2011/04/animated-customized-popup-transparent.html

Answer 2

Now I understand my problem.

I created an XML file in my drawables folder, which looks like this:

 <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle"> <gradient android:startColor="#00CC66" android:endColor="#009966" android:angle="270"/> /shape> 

In my toolbar, I set the background to this resource.
