Custom Component in android - android

I have created custom component with a Button Bar on the Bottom of
the screen and a Title and status bar on the top of the screen. I want
to include this custom component in every one of my Activities. Now,
in a any given activity, how do I go about adding content on the
screen (say a button in the middle of the screen) in a addition to my
custom component thats ever present?

How about adding a base layout with can contain the header and footer that you use everywhere and then have a stub in the middle that you can inflate with whatever you like?
I think that will solve your problem.

How to set up footer in in a android fragment?

I want to set a footer in android fragment. I am using appcomat for action bar and would like to have a bar simialr to action bar with as footer.
Footer will display some information as text .It wont have any clickable buttons.
I have create a mockup of footer as shown below.This will then contain some text.
Note the color of footer should be same as action bar.
Also the UI looks very ugly.How can i make it better?
answering my own question : I found the following way better.
Use nested layouts
Android: 2 relative layout divided in half screen

how can I implement common Bottom bar which behave like tab?

I have implement bottom bar as show below I achieved this using view flipper, its work perfect but when I select any one item to start new activity, its blink because of activity change.
I want to make this bottom-bar behave like as tab in which only tab change and it wont blink activity.
Design a seperate layout with the Bottom images and their behavior (like using selector etc to change state when you click on it ) and add that layout to your Activity XML using
<include> </include> tag

Creating an Android Nav Bar that replaces button with image when that activity is active

I am looking to create a Nav Bar in my Android application that functions very similar to the Nav Bar used by the Netflix app. There will be 4 buttons aligned horizontally. When one of those buttons is selected, the appropriate activity loads and that button is replaced by an image.
There are multiple ways I can achieve this, but since I am new to programming for Android, I figured I'd ask the community first. I list the first two that come to my head below.
Create a Linear Layout and define a separate layout for each activity. The Layout would include two more linear layouts, a horizontal linear layout for the nav bar and a vertical layout for the content.
Create a custom ui component named nav bar that extends a linear layout (based upon earlier threads I have seen about nav bars on here). Inflate that layout for each activity, then make a framelayout that overlays an image on top of the active button (the button that was just pressed). Then create onButtonClick listeners for each button except for the active button.
I'm not sure if there is a better way to achieve this and I am open to any suggestions. Any feedback would be great.
I'm not sure how the netflix app looks, but you might want to check out ye good olde tab-layout? ( http://developer.android.com/resources/tutorials/views/hello-tabwidget.html )

Custom title bar vs. layout with header

I recently thought of adding a custom title bar to my app (with "find me" and home button and such) and then I thought what is the reason of using a custom title bar at top instead of just a normal layout and using it as an include tag at the top of my XML's
What are the pros and cons of each? Is there realy a difference?
EDIT: one difference ive found so far is that the custom title bar has a shadows automaticly
For having back and home button titlebar, you should define normal layout for the same. Because it is easy to implement as compared to customized the native title bar. And we can create normal layout as we wants with any color/height/width/image backround/etc.
I suggest you to go with defining normal layout for the title bar instead of customizing the native title bar.
You can extend LinearLayout to create a new layout with your title bar. The advantage is you can then customise the title bar for different activities that use it. Some may not want to display the find button for instance.
If you use include in XML you don't have the same flexibility.
I would create a custom layout with the title bar.

Android creating Bottom Bar Menu

I want to have an static bottom menu bar exist through out the applications in every page visible at bottom all the time. I have designed the menu bar but i am confused whether i have to integrate the menu code with every layout xmls to make menu visible in every page and write the code in every activity class to perform functions on menu clicks. Or if there is any other way i can create a common bottom bar that lies with every page with writing the code of menu in a single activity class.
Well the best way in my opinion , is to create a bottom bar xml file , and include it in every Activity's xml file
<include android:layout_width="fill_parent" layout="#layout/bottom_bar" />
where your bottom bar xml file name is bottom_bar.xml

There is also the include route:
Common layout in all tabs
What you are probably looking for is one Activity with a TabBar with tabs at the top and buttons at the bottom: Android: Tabs at the BOTTOM
Then you can use different Views that correspond to Tabs instead of separate Activities.
