How to set line-height textView on Android

I give below attributes that I use textView in my application. ( Green text in middle )
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textSize="20sp"
android:textStyle="bold"
android:gravity="center_horizontal"
android:text="10/9"
android:id="#+id/estimate_fertility_date"
/>
However, there are spaces like the example picture. I want to set these spaces because when App initialize, It seems awful.
I have researched about 1 hour and I found some answers but They are not which I want answers.

It 's not easy to get absolutely no text padding in a normal TextView. One way is to can set a minus margin for the TextView, or just use textview.setIncludeFontPadding(false) to reduce padding to some degree.

Adding negative values to margin does it help you?
<TextView
android:layout_marginTop="-10dp" />

Align text and images on buttons

I am trying to place text under an image on my button. I am using the following code to display the image on the left, and the text on the right.
<Button
android:id="#+id/mango"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:drawableLeft="#drawable/mango"
android:gravity="left|center_vertical"
android:text="#string/mango_button"
android:padding="15dp"
android:onClick="fruit" />
I understand that the line:
android:gravity="left|center_vertical"
Makes this work - but I don't really understand how. I'd like to know if I can make the image stick to the top, and the text be placed below it in the same style.

I'm blind. The line
android:drawableLeft="#drawable/mango"
is where I need to make the changes - not the gravity.
android:drawableTop="#drawable/mango"
gives me what I want, pretty much.

Off-center alignment of text inside a TextView

I have a layout/alignment problem with a TextView which I haven't yet been able to find a solution for, that is, I want to align text off-center inside a TextView horizontally.
To give a little more context, I have an ImageView and a TextView side by side, the ImageView touching the left edge of the screen and the TextView filling the rest of the screen horizontally, like this:
[-img-|-----text-----]
The TextView is configured as singleLine="true" and maxLines="1", so that it will be truncated if its too long for its horizontal space. My aim is to align the text in the center of the screen, not the center of the TextView, because there are other elements on the screen that are aligned to the center and I need the text aligment to match that.
So, if I use gravity="center" on the TextView, I get the image above, but what I actually want is
[-img-|--text--------]
I tried putting image and text in a RelativeLayout, so that the TextView actually touches both edges of the screen, which does what I want with respect to the alignment, except that if the text is long enough, the first characters will be hidden by the image, since the TextView lies behind the image view.
I also experimented with margins, padding and a compound drawable to the left, but the text is always centered relative to the available space (which I would consider the expected behavior).
Does anybody have any clues on how to achieve this alignment, i.e. relative to the center of a different component than the TextView, maybe programmatically at runtime? Thanks in advance for any helpful advice.
Edit: user Budius suggested using padding to the right to achieve a centered alignment which works but leads to long texts being truncated before the right edge of the TextView is reached and I'm looking for a solution that avoids that, i.e. that uses the entire avilable space, if possible.

I believe that will center it and the move 20dp to the side.
gravity:centre padding:right=20dp

Try using
android:layout_weight="1"
if it helps you..

I know this is not the correct approach than too give it a try..
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight=".33"
android:src="#drawable/ic_launcher" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_weight=".33"
android:gravity="center"
android:text="text" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight=".33"
android:src="#drawable/ic_launcher"
android:visibility="invisible" />

Split button text into two sections

I am trying to port my WP7 app to android.
Does anyone know how I can layout the text on a single button so that some text appears aligned left and other text appears aligned right? (See below). I need access to be able to dynamically change the percentage number on the right side using code but the text on the right is just static.
Anyone know the answer to this?
The image is here:

Yes you could make it two buttons.
Remove all padding and margin from between them.
Set the same background drawable.
And just ensure when the left is clicked it invokes the right's onPress method (so it looks as if they depress together).
Or wrap the buttons/imageviews/textviews in a layout and perform the onClick on that.

I would use a RelativeLayout for this.
<RelativeLayout
android:width="fill_parent"
android:height="wrap_content"
android:clickable="true"
android:background="#18a2e7"
android:padding="10dip">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Something" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_align_parentRight="true"
android:text="0%" />
</RelativeLayout>

How can I make button text extend outside 9 patch content area?

I have a row of buttons with custom 9 patch images, and variable length text. I would like the buttons to be the same height. When the text is long enough to wrap, it expands the button size, making the button with wrapped text bigger than the others. I'm laying these buttons out in code in linear layouts. I can fix the size of the button, but then it just cuts off the bottom. How can I make the text take up more of the padding space of the button, so that the text butts up against the top line of the button?

9patch content area is just used to set a padding. If you change the button's padding you will override the one set by the 9patch.
edit
try something like this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<Button android:text="ButtonButton"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:paddingTop="0dp"
android:paddingBottom="10dp"/>
<Button android:layout_width="wrap_content" android:text="Button"
android:layout_height="match_parent"/>
<Button android:layout_width="wrap_content" android:text="Button"
android:layout_height="match_parent"/>
</LinearLayout>
this way the button will be as high as the others. Sadly, I don't know if it depends on the original button's 9patch that might have asymmetrical paddings, but I can't make the text align with that from other buttons (I think gravity is by default set to center). Maybe with your 9patch it works though. (EDIT: oh, but if you'll have two lines of text who cares about alignment)

Ultimately I was unable to find a nice way of doing this without creating a custom view class.
