So I am using the techniques in this thread to use a custom background for my titlebar. Unfortunately the framework places my layout inside a FrameLayout ( title_container ) which has padding as seen below.
Is there anyway to remove the grey borders? The frame layout is defined in com.android.internal.R.id.title_container , so accessing the frame by ID would be fragile.

There is actually no need to use a custom layout to customise the background image. The following code in theme.xml will work:
ReplyDelete<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="TitlebarBackgroundStyle">
<item name="android:background">@drawable/header_bg</item>
</style>
<style name="Theme.OTPMain" parent="android:Theme">
<item name="android:windowTitleBackgroundStyle">@style/TitlebarBackgroundStyle</item>
</style>
</resources>
However, if you do actually want to use a custom title bar, then the following code will remove the margin:
ViewGroup v = (ViewGroup) findViewById(android.R.id.title);
v.setPadding(0, 0, 0, 0)
title_bar_background was set as the ID of the background image in the XML. I set android:scaleType="fitXY".
I was struggling with this same issue and now I have the answer!
ReplyDeleteAs you probably have seen several places, you need to create a themes.xml resource:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="MyTheme" parent="android:Theme">
<item name="android:windowTitleSize">44dip</item>
<item name="android:windowTitleBackgroundStyle">@style/WindowTitleBackground</item>
</style>
</resources>
Note it is not often mentioned in the sites talking about custom title bars you need to select this theme at the view, activity, or application level. I do it at the application level by adding android:theme property to the application:
<application android:icon="@drawable/icon"
android:label="@string/app_name"
android:theme="@style/MyTheme">
You also need a styles.xml to define that WindowTitleBackgroundStyle. Unlike the various versions of this file I have seen floating aroung the web, I have added one additional line to the file that sets the padding to 0 which gets rid of the padding you are complaining about:
<?xml version="1.0" encoding="UTF-8"?>
<resources>
<style name="WindowTitleBackground">
<item name="android:background">@android:color/transparent</item>
<item name="android:padding">0px</item>
</style>
</resources>
There is a lenghty thread over on anddev.org that may be able to help you out

I have followed it and successfully created my own title bar which allows me to set the padding.
Xml for my title bar:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout android:id="@+id/header"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="38px" android:layout_width="fill_parent"
android:background="@drawable/gradient">
<TextView android:id="@+id/title" android:layout_width="wrap_content"
android:gravity="center_vertical" style="@style/PhoneText"
android:layout_alignParentLeft="true"
android:text="New Title" android:background="@android:color/transparent"
android:layout_height="wrap_content" android:layout_alignParentTop="true"
android:padding="5dip" android:layout_marginBottom="7px"/>
<TextView android:id="@+id/time" android:layout_width="wrap_content"
android:gravity="center_vertical" style="@style/PhoneText2"
android:layout_alignParentRight="true"
android:text="Test Text" android:background="@android:color/transparent"
android:layout_height="wrap_content" android:layout_alignParentTop="true"
android:padding="4dip" android:layout_marginBottom="7px"/>
</RelativeLayout>
The above creates a small gray bar with text aligned to the right and left sides
