How do I get rid of the white bit around the button? I don't want the button transparent, but I want the white bit around it. I've got Google Maps behind the button.
I've tried android:background="@android:color/transparent", on the Button, but it's only the button that becomes transparent (not the white bit around it).
How do I do this in XML?
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MyLocation" >
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:background="@android:color/transparent"
android:gravity="center" >
<Button
android:id="@+id/filter"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="filterMenu"
android:text="@string/filter_button" />
</FrameLayout>
<fragment
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.SupportMapFragment" />
</LinearLayout>

try this:
MybuttonName.getBackground().setAlpha(0);
0= Completely transparent. 255 Completely opaque.

How about this.
Button filter = (Button) findViewById(R.id.filter);
filter.setBackgroundColor(Color.TRANSPARENT);

How about setting the background of RelativeLayout
to transparent?
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@android:color/transparent" >
<Button
android:id="@+id/filter"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:onClick="filterMenu"
android:text="@string/filter_button"
/>
<fragment
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.SupportMapFragment" />
</RelativeLayout>
And why not using FrameLayout
anyway? It's better in performance than RelativeLayout
.
<FrameLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:background="@android:color/transparent" >
<Button
android:id="@+id/filter"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="filterMenu"
android:text="@string/filter_button"
/>
<fragment
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.SupportMapFragment" />
</FrameLayout>
