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" />

I'm trying to achieve the following layout: a fixed width TextView aligned to the left of its parent, with the text inside it aligned to the right side of that TextView (that's why fixed width, can it be done other way?) and the rest of the parent is filled with a drawable (simple line). Like this:
It's a ListView containing 2 types of rows and the layout for the rows with lines is quite trivial - LinearLayout with TextView and ImageView (I can post the exact code later if needed). And I'm getting a warning that it could be replaced with a single TextView with compound drawable.
I'm all for optimization so I really tried to follow that advice. Unfortunately I wasn't able to get the same result - the line is either constrained to TextView's width or text is aligned to the right side of the ListItem, now to fixed position.
Am I missing something?
Edit: Apparently it is not actually possible and since there are some other complications (the drawable is now a level-list drawable, which is not always a line and sometimes it has a non-fixed height that I have to set) I will leave it as it is now - linear layout, containing one TextView and one ImageView.
I don't think that you're missing anything. The TextView compound drawable features are not very customizable and in general are not worth the time you spend trying to get them to look right. Some lint warnings are a little overzealous and premature.
The optimization that the lint refers to is something that is better attributed for a fixed size image. In your case, the line has to stretch the rest of the screen length and as such it is not something that can be done with a textview with compound drawable. This kind of lint warning is more of a suggestion rather than something that MUST be done and is detected by just checking for a linear layout with only a textview and an imageview rather than checking what would need to go in the image view. If you already have it working the way you did it I think you should leave it alone.
Your view create from this -
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<TextView
android:id="#+id/time"
android:layout_width="#dimen/today_time_width"
android:layout_height="wrap_content"
android:layout_gravity="left"
android:gravity="right"
android:layout_marginRight="5dp" />
<ImageView
android:layout_gravity="center"
android:id="#+id/border"
android:layout_width="match_parent"
android:layout_height="#dimen/today_current"
android:src="?attr/item_boundary" />
</LinearLayout>
There is no way to achive this using only standart TextView. If you really want to reduce view count you can create your custom TextView class, set layoutWidth to matchParent and draw line from text end to right border. But it's not worth to be doing. Some extra views won't slow your list.
I am not sure if you will be able to achieve what you really want to , but then you could change the linear layout in the link you posted to something like this:
<RelativeLayout
android:id="#+id/relTrial"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/txtTime"
android:layout_width="100dp"
android:layout_height="wrap_content"
android:gravity="right"
android:text="12:45 AM"
android:layout_alignParentLeft="true"/>
<LinearLayout
android:id="#+id/lnrSep"
android:layout_width="fill_parent"
android:layout_height="1dp"
android:gravity="bottom"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
android:layout_centerVertical="true"
android:orientation="horizontal"
android:background="#android:color/darker_gray"
android:layout_toRightOf="#+id/txtTime"
android:layout_alignParentRight="true"></LinearLayout>
</RelativeLayout>
This way the time text will be right aligned although being at the left side, and the line will also be visible.
Hope that helps.
If I got you right, you want to add bottom border to list view item?
What about to try this:
android:drawableBottom="#drawable/line"
In edittext the text is coming leftmost corner. but i want to display the text after one space . so it should be more readable.
Any one can help me in this problem.which tag in edit text i have to use.
Try providing margins around your EditText Background like this,
<EditText android:id="#+id/tickets_value"
android:layout_width="50dip"
android:layout_height="wrap_content"
android:gravity="center"
android:padding="5dip"
/>
You can use either the padding or the margin element of the view.
While margin offsets the entire view the padding offsets the content within the view.

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>
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.
I'm trying to create standard button in android with a background and some text in front but some fairly specific alignment. I want the text to be centered vertically and on the left with 20dp of padding. The alignment works but the padding doesn't. I know I could probably get the desired effect by putting a few spaces in the text but that seems like a hack and next I want to do a similar thing but with the text at the top so I would prefer a more elegant solution.
Here's what I have:
<Button
android:layout_width="312dp"
android:layout_height="95dp"
android:id="#+id/gv_music_button"
android:text="Music"
android:textSize="30sp"
android:paddingLeft="20dp"
android:gravity="left|center_vertical"
/>
My mistake, padding was working correctly. Just didn't appear to be.
