Android make part of activity transparent -

Android make part of activity transparent -

i have next layout:

<relativelayout> <textview android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/hello_world" /> <linearlayout android:layout_width="fill_parent" android:layout_height="200dip" android:layout_alignparentbottom="true" > </linearlayout> </relativelayout>

i want create linear layout transparent, meaning, content previous activity on activity stack should visible in linear layout region.

i have tried using setalpha(0) linear layout; create transparent, shows activity background color in linear layout region.

i have tried setting android:theme activity @android:style/theme.translucent.notitlebar, create whole activity show content of previous activity.

can suggest way?

thanks.

just clear, activities not visible objects. views see on screen -- in particular see view attached activity. in case view relativelayout , contents.

when create linearlayout transparent, shows background color of relativelayout. if want see behind relative layout create background color transparent, too.

<relativelayout android:backgrond="#00000000"> ... <linearlayout android::background="#00000000"> ... </linearlayout> </relativelayout>

of course of study want utilize named color resource rather "#00000000"
