how to center android Textview element at bottom of the screen

I have the android xml layout using DroidDraw :

I need to bottom align the last Textview (Yellow one as indicated in the print screen).
i.e.
I need this :

Try using
android:alignParentBottom="true"
If I see correctly that the parent ViewGroup of your TextView is a RelativeLayout

Set the parent relative layout property to:
android:layout_gravity = "bottom | left"

In Relative layout use:
android:alignParentBottom="true"
and In Linear layout use:
android:layout_weight="1.0"
android:gravity="bottom|right"

This post did the trick.

I needed to implement layout_weight on my layouts. Basically defining weights for header, content and footer

Why can't I put a aligned right TextView inside a TableView?

In my layout, I really need to the TableView be the root view, but inside it I need very much a single TextView to be aligned to the right border of the screen, but I keep receiving the warning: Invalid layout param in a TableLayout: layout_alignParentRight activity_main.xml
What should I do to have a aligned textview inside a TableView?

You can use gravity in TableLayout, Try to set android:gravity="right" to TextView

android:layout_alignParentRight="true" works fine for me if it's not working then check your parent try fill_parent on the parent or try moving it from it's parent layout hope this helps

Android XML: Good examples to use gravity rather than layout_gravity

I have done some basic xml layout from the Internet and I am confused as to what android:gravity would be used for vs android:layout-gravity. The UI designer seems to respond well when I change the layout_gravity, but I get no response to the regular gravity? What is up with this?
Is this similar to layout parameters with fill-parent and match-parent? one is gone now.

android:gravity is a statement from a parent to its content, indicating where the content should slide within the available parent space (if there is room for such sliding).
android:layout_gravity is a request from a child to its parent, asking that it be slid in a certain direction (if there is room for such sliding).

layout_gravity - It contains and it belongs to component's parent layout. Like if you set one TextView in LinearLayout, LinearLayout's width is fill_parent, but TextView basically will set at left-top. So now if you would give layout_gravity=right then your TextView will be shifted to top-right corner. But the text will not change its place. i.e. you had been wrote "Hello world" then "hello world" will not be changed to right, but its parent textView will be changed to right. So here in this case it will belongs to LinearLayout, means parent Layout.
gravity- It contains and it belongs to TextView as per above explanation. if you will give gravity="right" then "Hello-world" text will go to right-top corner of TextView not LinearLayout.

How to set a TextView at the bottom of the screen

I have this layout:
It was a bit tricky to put ListView inside ScrollView, but it worked.
When the list is large and the scroll appears when scrolling .. everything up, including the form. That is ok!
Now I would like to put a TextView fixed at the bottom of the screen. As a total
Tried to wrap everything with a RelativeLayout put layout_weight = "1" in ScrollView. Worked. But when the keyboard appears, rises along the TextView and do not want it.
How do I set a TextView at the bottom of the screen, without moving when the keyboard appears?

Put everything in a relative layout. Add the TextView to the relative layout, set layout_alignParentBottom on TextView. Then on the ScrollView set layout_above referencing the TextView.

Follow the design hierarchy:
<LinearLayout.....>
<ScrollView>
<You Old Views/>
</ScrollView
<TextView> .. </TextView>
</LinearLayout>

Android top left button

I want to make an about button in the top left. I tried:
android:layout_gravity:"top|left"
but it doesn't work , I searched and all what I found was using RelativeLayout and if I use that I'll have to make all my layout from beginning and it's not that good like the linear layout.
Couldn't post the code here. So this is my code on pastebin

Here you have given android:layout_gravity="center" to the Linear Layout so it is going to set gravity of the layout and as center and your About Button is child of layout its to going to set in center and you have given Margin_top also.Try to remove gravity amd Margin_top and you can see the result, the button will be top|left of the screen.
