I am using TextViews to render talk bubbles, which are formed from 9-patch .png images stretched to fit whatever a character says. The same TextView is programmatically reused, resized, and shifted to different places on the screen as the conversation occurs.
Everything looks good except sometimes there is a thin (probably 1 pixel) black line above and below, at the edges of the TextView space (the .png's themselves have a transparent background).
I've been searching online for a week, but found no one with this exact same complaint or any solutions based on anything even vaguely similar.
Any thoughts?

Why are you using TextView? If you want to show text on some background why not to use ImageView.
In my case it was solved by adding "android:background="#android:color/transparent" to the EditText element

Long time lurker, first time poster here!
I'm having a problem specifically on my Kindle Fire where when I insert an image (in this case a header and footer) into a relative layout and set the width to "match_parent" or "fill_parent", there is a white border around the sides.
However when I put an image into a linear layout and set the exact same parameters, it works properly.
It works perfectly on phones and my Samsung tablet, I just can't figure out what's going wrong on the Fire.
I'm hoping someone here has a fix for this problem. I can't find anything about it through google or the StackOverflow search.
Here is the XML code for my header and the relative layout.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="*****************.MainActivity"
android:background="#drawable/background_xhdpi">
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/imageHeader"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:src="#drawable/header_xhdpi"
android:adjustViewBounds="true"/>
(Example of the problem)
Thanks for your time!
To anyone else having this problem a fellow developer gave me the solution.
Add this to your ImageViews that aren't stretching properly:
android:adjustViewBounds="true"
android:scaleType="fitXY"
I am very new to this forum and really need help in something I got stuck in during developing the app.
This is the image I am using as my background (I named it SampleBG in xml):
https://i.gyazo.com/946507c2690c8170b54a1ace752906bd.png
Basically, this is what I want my design to look like:
https://i.gyazo.com/896e29846dfd9e4bc9ab15ca39f9a796.png
And for smaller devices, it automatically resizes and looks like this:
[i.gyazo.com/f4278339cc8f246187c011474796a12c.png]
And when I switch to a tablet device, it automatically looks like this:
[i.gyazo.com/1b0e233a0b1731148664e0ac78a05f08.png]
And the above is exactly what I want it to look like. The wooden signs are in the same position for all sizes...
But the problem is:
I want the wooden signs to be clickable, because they are meant to be buttons.
So, I tried to use a button widget and made it transparent and placed it over the wooden signs... it worked but it only worked for that particular size I designed it for (designed it for Nexus 5 to be specific).... However, when I switched to the Nexus One layout, or Nexus 9 layout, etc, the buttons weren't placed correctly over the wooden signs and thus didn't work.
I want a way to make the wooden signs clickable and and the buttons to be fixed with the signs for all device sizes/etc, and at the same time.
I would prefer an xml solution but a programmatic solution is nice too.
Here's the layout code right now, it just using the background image right now....
`<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/sampleBG">
</RelativeLayout>`
NOTE:
I have tried using the door image as the background only and then adding the wooden signs manually by using the ImageButton widgets, but the wooden signs were being placed differently for different screens and it looked odd, so therefore I fixed the wooden signs with the background (in Photoshop).. now I just want the signs to be clickable.
This is a sample code that you can use, in order to achieve this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#mipmap/ic_launcher"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context="com.test.androidtestapp.MainActivity">
<ImageButton
android:id="#+id/equationsButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="#+id/equationsOfTheWeekButton"
android:layout_centerInParent="true"
android:layout_margin="20dp"
android:background="#mipmap/ic_launcher"
android:contentDescription="Equations Button"
android:onClick="equationsButtonClick" />
<ImageButton
android:id="#+id/equationsOfTheWeekButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_margin="20dp"
android:background="#mipmap/ic_launcher"
android:contentDescription="Equations Of The Week Button"
android:onClick="equationsOfTheWeekButtonClick" />
<ImageButton
android:id="#+id/settingsButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/equationsOfTheWeekButton"
android:layout_centerInParent="true"
android:layout_margin="20dp"
android:background="#mipmap/ic_launcher"
android:contentDescription="Settings Button"
android:onClick="SettingsButtonClick" />
</RelativeLayout>
You need to slice your image and then just change the background attributes in the code above. When you achieve that, you can change the background to a selector where you can change the image depending on the different states -> when it's clicked, focused, normal; that would make it more user friendly.
The wooden signs should NOT be on the background image.
Instead, make a real background image (ie. with only the "door" background) and make separate images with the signs.
Then use these images to build your buttons.
Edit: I did read your note about the fact that you tried that, but you should definitively go this way. Another advantage is that you'll be able to easily make the buttons reacting to the user click, with "onPress" states, which would be impossible (or at least difficult and ugly) with a single background image.
You can separate wood pics that you want to be button and give them as a background for buttons. For example, you named the wooden pics as 'wood1.png' , 'wood2.png' and 'wood3.png' and by this sample code you can set them for background image for buttons :
<ImageButton
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/wood1"
/>
Or you can design your app by your own solution that described but you should create your app design by different layout for different size device :
layout-large
layout-small
layout-normal
layout-xlarge
layout-xxlarge
you can search about autoLayout design in android app and find your solution better..
Background:
I've got a layout that consists of 6 items layed out as a grid (2x3). All items are as wide as half the screen (minus a little margin on each side). Each item is a RelativeLayout that contains an ImageView (the background) and a TextView (the label). The label is set to wrap the text, and it's allowed to grow almost as wide as the image it sits on top of. After that it will break into two lines.
Problem:
Everything looks good as long as the text fits on a single line (see top element in picture). The background wraps the text nicely. However, when the text is displayed on two lines the background gets too wide (see bottom item in picture). It fills up the maximum allowed width even though the text on the first line doesn't take up that much space. Is there a way to make the background wrap the text in the same way as it does when only one line is used?
Picture:
Layout XML:
<ImageView
android:id="#+id/item_image"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scaleType="centerCrop" />
<!-- some stuff I had to remove... -->
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:paddingBottom="11.33333dp">
<!-- some other stuff I had to remove... -->
<!-- the gray background color is set to the TextView below programmatically together with the text itself. -->
<TextView
android:id="#+id/item_text_label"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="5.33333dp"
android:paddingLeft="7.33333dp"
android:paddingRight="20dp"
android:paddingTop="1dp"
android:paddingBottom="5.33333dp"
android:layout_alignParentRight="true"
android:gravity="right" />
</RelativeLayout>
</RelativeLayout>
One of the possibility of such problem is textSize.
It depends on how you are setting and which measuring unit you are using to set textSize of your TextView.
dp,sp,pt and in may cause to create such problems.
So try to go with mm or px specifically.
And as per my testing px will give you the best result.
EDITED :
Add following attribute to your TextView in layout file.
android:gravity="right|start"
Instead of :
android:gravity="right"
Thanks.
I am trying to have an image be fitted, and have a layout below it with some black background and whit text. My problem is that the layout ends up leaving space between the image and the text itself, and I don't understand why:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<ImageView
android:id="#+id/image"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scaleType="fitStart" />
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="15dp"
android:layout_below="#+id/image" >
<TextView
style="#style/text_overlay"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!-- Couple more elements -->
</RelativeLayout>
</RelativeLayout>
I would want this second RelativeLayout of 15dp touch the bottom of the image, but unless I change the image height to something small, it leaves some space. This layout specifies how to display an image + some text below it, but I have a total of 4 images that use this layout to get loaded on the screen, in a 2x2 display. (Each image takes 25% of the screen).
Any idea how to make the RelativeLayout align exactly with the bottom of the image please?
I do not fully understand your question though I think you might have a look at the launcher layout for my Newspaper Puzzles app...
http://code.google.com/p/newspaper-puzzles/source/browse/np/res/layout/launcher_layout.xml
or perhaps from the Open Sudoku Game look at the number pad layout found here:
http://code.google.com/p/newspaper-puzzles/source/browse/np/res/layout/s_im_numpad.xml
Use the ADT tools to get the right layout is probably best if possible but I know sometimes it is difficult to use to get specific results I still recommend using the xml tools included in the Android Development Tools.

I would recomend using a compound drawable if you're trying to put text directly below an ImageView.
See the following question for more details: How do I use a compound drawable instead of a LinearLayout that contains an ImageView and a TextView
I have the following layout:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="#EAEAEA">
<ListView
android:id="#+id/xxx"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:textColor="#464C59"
android:divider="#A4C539"
android:dividerHeight="1px">
</ListView>
<ImageView
android:id="#+id/home_bottom_bar"
android:src="#drawable/bottombar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:clickable="true"/>
</FrameLayout>
The goal is to have some sort of advertising bar at the bottom of the activity (which contains a list of items). It works ok, except for one thing! There is some sort of extra space just under the bar (it's very small but it's noticeable enough). By the way, all the paddings are set to 0 so where does this space come from?
Thanks!
EDIT
After investigating the issue, it turns out that the custom background (#EAEAEA) is causing this extra space. Still don't know how to fix this though.
When you mention that it is a small extra space, it may be the tiny gradient at the top and bottom. Created by ListView, when it is made scrollable.
You may read about ListView Backgrounds, this should give you the idea on how to fix it, if it is caused by this special gradient.
This gradient line can apparently also be removed: extra line in tab host
You may want to use the merge tag since every activitys base layout is a FrameLayout.
(This may cause the padding. Im not 100% sure on this one though)
