I am trying to get the TextView, "tv_amount" to stay on the right side of the screen. I have tried using android:gravity="right" but that hasn't been working for me. Anyone have any suggestions?
Image of emulator running this code:
<?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="45dp"
android:gravity="center_vertical"
android:orientation="horizontal">
<ImageView
android:id="#+id/iv_icon"
android:layout_width="40sp"
android:layout_height="40sp"
android:background="#drawable/circle_border"
android:padding="6sp"
android:layout_marginLeft="6dp"
android:src="#drawable/food"/>
<TextView
android:id="#+id/tv_label"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_marginStart="12dp"
android:text="Yummy Pizza"
android:textSize="20sp" />
<TextView
android:id="#+id/tv_amount"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginEnd="12dp"
android:gravity="end"
android:text="$25"
android:textSize="25sp" />
</LinearLayout>
I am expecting the transaction or "tv_amount" to stay be right justified so that end of the number is staying towards the right side of the screen.
I tried using :
android:layout_weight="0"
android:layout_gravity="end"
android:gravity="right"
but these don't seem to work obviously. I am a beginner when it comes to android development and can't seem to find any answers that have helped anywhere else. They all say to use android:gravity or some other alternative. Maybe there is something in my code that doesn't allow that.
Try it like this:
Splitting the content into left and right will result in the weight and gravity properties working. Check out this layout below.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:id="#+id/tv_title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="Title"
android:textSize="20sp" />
<!--Separate layout aligned to the left, containing an image and a yummy pizza label. -->
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<LinearLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:orientation="horizontal">
<ImageView
android:id="#+id/iv_icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
<TextView
android:id="#+id/tv_text_left"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Text Left"
android:textSize="16sp" />
</LinearLayout>
<!--Display the pizza price on a separate label aligned to the right -->
<TextView
android:id="#+id/tv_text_right"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="right"
android:text="Text Right"
android:layout_weight="1"
android:textSize="16sp" />
</LinearLayout>
</LinearLayout>
I am dumb. The issue wasn't with the code in my individual recycler view layout code. It was with my activity_main.xml. I set the recycler_view width to "wrap_content" when it should have been "match_parent." Rookie mistake.

I am making the list view in which I have a image view and to its left I have to align the TextView which should have text in the center of it not the bottom of it. I have set the gravity but its only looking good in the design but when I run my app and data is fetched in list view then the text gets set in the bottom .
I will show you what I mean by this.But first let me show you how I am doing to align this
<RelativeLayout
android:id="#+id/block_address"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="2dp"
android:orientation="horizontal">
<ImageView
android:id="#+id/iv_address"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/pin" />
<TextView
android:id="#+id/row_address"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_alignBaseline="#+id/iv_address"
android:layout_alignBottom="#+id/iv_address"
android:layout_marginLeft="3dp"
android:layout_toRightOf="#+id/iv_address"
android:gravity="center|center_vertical"
android:text="Address Goes here"
android:textColor="#AAAAAA" />
</RelativeLayout>
and this is how I am getting this
And this is what I want it to be
as you can see in the second picture I want this type of adjustment. and in design preview it is showing me design just like it is expected. But When I run the app it just showing me text like i showed you in picture one.
Please tell me what i am doing wrong and How to constrict this not to get out of allignment.
Replace whole code with :
<TextView
android:id="#+id/row_address"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:android:drawableLeft="#drawable/pin"
android:drawablePadding="10dp"
android:gravity="center|center_vertical"
android:text="Address Goes here"
android:textColor="#AAAAAA" />
You can add a drawable icon
<TextView
android:drawableLeft="#drawable/..."/>
Replace your TextView with this:
<TextView
android:id="#+id/row_address"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_alignTop="#+id/iv_address"
android:layout_alignBottom="#+id/iv_address"
android:layout_marginLeft="3dp"
android:layout_toRightOf="#+id/iv_address"
android:gravity="center|center_vertical"
android:text="Address Goes here"
android:textColor="#AAAAAA" />
Use LinearLayout Instead of RelativeLayout as acheiveing something like this is pretty easy in LinearLayout
<LinearLayout android:layout_width="match_parent"
android:layout_height="150dp"
android:orientation="horizontal">
<ImageView
android:id="#+id/iv_address"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="3"
android:src="#drawable/andro"/>
<TextView
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="7"
android:text="Hello World"
android:gravity="center"/>
</LinearLayout>
Try LinearLayout instead of RelativeLayout. because its easy to align.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:id="#+id/block_address"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="2dp"
android:orientation="horizontal"
xmlns:android="http://schemas.android.com/apk/res/android">
<ImageView
android:id="#+id/iv_address"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/logout" />
<TextView
android:id="#+id/row_address"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_marginLeft="3dp"
android:gravity="center|center_vertical"
android:text="Address Goes here"
android:textColor="#AAAAAA" />
</LinearLayout>
I have the xml code shown below. Everything is working as it should except the final textView( id locationTextView) which won't stay right. I want it to stay as right as possible, but I can't do that(it still appears straight after the linear Layout).Should I set a left margin?. And for the textView1 how can I make it to show only a certain part of the whole text, because I have texts of different lengths and they ruin the layout.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"

android:layout_width="72dip"
android:layout_height="72dip"
android:layout_margin="3dip"
android:adjustViewBounds="true"
android:contentDescription="#string/descr_image"
android:scaleType="centerCrop" />
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">

android:id="#+id/item"
android:layout_width="wrap_content"

android:layout_marginTop="5dp"

android:text="Medium Text"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="#33CC33" />
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:text="TextView" />
</LinearLayout>
<TextView
android:gravity="right"
android:layout_width="72dip"
android:layout_height="72dip"
android:layout_marginTop="0dp"
android:textAppearance="?android:attr/textAppearanceLarge"
android:id="#+id/locationTextView"
android:layout_gravity="right" />
</LinearLayout>
</RelativeLayout>
Try android:layout_weight="1" or some other value for your locationTextView. You can also try out android:weightSum="3" (or that is appropriate instead of 3) on your root LinearLayout. Assign proper weights to your different child views. You can get help here
For showing text in a presentable way, you could use android:ellipsize="marquee" or other options available.
I have the following layout for a ListView item:
<?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:padding="5dp">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/item_icon_image"
android:layout_centerVertical="true"
android:layout_alignParentLeft="true"
android:src="#drawable/m" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Business Name"
android:id="#+id/item_title_text"
android:layout_toRightOf="#+id/item_icon_image"
android:layout_marginLeft="3dp"
android:textStyle="bold"
android:textAppearance="?android:attr/textAppearanceSmall"
android:layout_alignTop="#+id/item_icon_image" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceSmall"
android:text="Distance"
android:id="#+id/item_distance_text"
android:layout_alignLeft="#+id/item_title_text"
android:layout_alignBottom="#+id/item_icon_image" />
</RelativeLayout>
And this is the rendered result:
As you can see there is a gap between the real text and the bottom of the image... I was expecting to have the bottom of the text matching exactly with the bottom of the image...so question is: How can I align the text to the bottom of the image?
(this also happens for the top text, but in the top instead)
EDIT:
For now I am using:
android:layout_marginBottom="-10dp"
But I wanted something more automatic, some solution that won't depend on dp or screen....but as commented, this might be impossible, because the View needs to make space for letter such as 'y', 'g' and 'j'....but I wish there could be something that will align it based on it's contents, so if there wasn't a 'g', it won't be saving this space.
You should add android:gravity="top" to your top text view and android:gravity="bottom" to your bottom text view to get the desired result.
Try this way,hope this will help you to solve your problem.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="5dp">
<ImageView
android:id="#+id/item_icon_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_launcher" />
<LinearLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_marginLeft="5dp"
android:layout_weight="1"
android:orientation="vertical">
<TextView
android:id="#+id/item_title_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Business Name"
android:textAppearance="?android:attr/textAppearanceSmall"
android:textStyle="bold" />
<View
android:layout_width="1dp"
android:layout_height="odp"
android:layout_weight="1"/>
<TextView
android:id="#+id/item_distance_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Distance"
android:textAppearance="?android:attr/textAppearanceSmall" />
</LinearLayout>
</LinearLayout>
Do it like this to acheive the desired result:
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceSmall"
android:text="Distance"
android:id="#+id/item_distance_text"
android:layout_alignLeft="#+id/item_title_text"
android:layout_alignBottom="#+id/item_icon_image"
android:gravity="bottom" />
The following is the XML of my layout. It explicitly states that the title, time and description TextViews should be under the image of the alarm. However, as the screen shot shows, the TextViews have moved into the ImageView. Why does this happen and how can I fix this? The problem only started happening when I added the scrollview.

Cute app :)
hmm... not sure why it's doing it, looks like you have the right code, without busting out eclipse. but i've also had some weird bugs with relativelayout that i didn't understand and didn't have time to debug.
i do know of an alternative way you can accomplish what you're looking for -
have a scrollview that encases a linearlayout instead of a relative layout. Do these things:
For the linearlayout, you can set orientation = vertical so that it's still a top down order.
For the part where you need two textviews where one is aligned to the right and the other is aligned to the right, you need another inner linearlayout with its orientation=horizontal. then have one element align parent left, and the other align parent right. add a weightSum=1 attribute to this linearlayout and have each of the two textviews layout_width=0.5 so that each is half the width of the screen
Apply a weightSum=1 attribute to your outer most linearlayout, and see each element inside so that it's layout_weight sum adds up to 1. layout_weight will allow an element to take up that much % of real estate on the screen. like if you set your imageView to have android:layout_weight=0.8 then it'll take up 80% of the screen... since mathematically, (layout_weight/weightSum) = (.08/1) = 80%
try to use that mechanism instead, and if should work :) if it's confusing i can give code
example
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:weightSum="1">
<ImageView
android:id="#+id/img_alarm"
android:layout_width="match_parent"
android:layout_height="0dip"
android:src="#drawable/alarm"
android:layout_weight="0.7"
android:contentDescription="#string/content_description_layout_alarm"/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="0.1">
<TextView
android:id="#+id/lbl_alarm_title"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:textSize="20dip"
android:textStyle="bold"
android:text="#string/empty"
/>
<TextView
android:id="#+id/lbl_alarm_time"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:textSize="20dip"
android:textStyle="bold"
android:text="#string/empty"
/>
</LinearLayout>
<TextView
android:id="#+id/lbl_alarm_description"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_weight="0.1"
android:maxLines="1"
android:ellipsize="marquee"
android:text="#string/empty"
/>
<Button
android:id="#+id/btn_stop"
android:layout_weight="0.1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginTop="5dip"
android:paddingLeft="20dip"
android:paddingRight="20dip"

android:gravity="center" />

i hope this deserves at least an upvote for the effort :D
I have problems getting some of my views aligned in a relative layout that I use inside a row of my listview.
Here is a screenshot from the layout builder in Eclipse, this is what I think it should look like:

The next image is from the emulator. Now the TestTestTest View is at the top and covers the name and distance Textviews.
(source: janusz.de)
This is my layout:
<?xml version="1.0" encoding="utf-8"?>

android:layout_width="fill_parent" android:layout_height="fill_parent"

Shouldnt align_parent_bottom put the view at the bottom of the cell in the list?
Try adding android:layout_alignParentLeft="true" as well; sometimes Views aren't displayed properly if it can't anchor the view with at least 2 points. Also, is this RelativeLayout used within a ListView? If so, you might find you have some difficulty getting it to look right. There was another question where someone was having a problem where the RelativeLayout looked right on its own, but not once it was included as part of a ListView. We didn't manage to figure out what went wrong so he had to use nested LinearLayouts instead.
