The imageView is not getting right-aligned in this linearlayout (If it matters this LinearLayout is actually a row in a list).
But if i use a TextView (its commented in code below) instead of ImageView, it successfully gets right-aligned.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:background="#FFFFAA"
android:orientation="horizontal" >
<TextView
android:id="#+id/txtTitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Title"
android:textAppearance="?android:attr/textAppearanceMedium" />
<!--
<TextView
android:id="#+id/labelNext"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="right"
android:text="> "
android:textSize="20sp"
android:textStyle="bold">
</TextView>
-->
<ImageView
android:id="#+id/iconNext"
android:layout_width="25dp"
android:layout_height="25dp"
android:layout_gravity="right"
android:layout_weight="1"
android:gravity="right"
android:src="#drawable/right_arrow" >
</ImageView>
</LinearLayout>
How do i get the imageView to the right-most edge of the LinearLayout row?
Use a RelativeLayout instead of LinearLayout because LinearLayout does not support it.
Use like this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:background="#FFFFAA" >
<TextView
android:id="#+id/txtTitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Title"
android:textAppearance="?android:attr/textAppearanceMedium" />
<ImageView
android:id="#+id/iconNext"
android:layout_width="25dp"
android:layout_height="25dp"
android:layout_gravity="right"
android:layout_weight="1"
android:layout_alignParentRight="true"
android:src="#drawable/right_arrow" >
</ImageView>
</RelativeLayout>
Or you can add empty view between your imageView and textView that fill empty space between them and your second textview will be "pushed" to right side:
<View
android:layout_width="0dp"
android:layout_height="1dp"
android:layout_weight="1"/>
Setting width to 0 and weight to 1 causes this view to fill whole available space, that is not used by other views. So it's size will be
width = (screenWidth-(imageView width+textView width))
If you only need a TextView with image on the right consider using a android:drawableRight parameter. Both LinearLayout with weights and RelativeLayout run measurement twice so leaving just TextView will be computationally faster.
<TextView
android:id="#+id/txtTitle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Title"
android:textAppearance="?android:attr/textAppearanceMedium"
android:drawableRight="#drawable/right_arrow" />
(Also please note that the arrow in ListView is against Android design guidelines)

I have a RelativeLayout within a LinearLayout and for some reason I can not get rid off the padding between the text and divider line of the first row.
How is it possible to align the Text / LinearLayout to the top?
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/file_row_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:gravity="top"
android:baselineAligned="false">
<ImageView
android:id="#+id/file_row_thumb"
android:layout_width="80dp"
android:layout_height="80dp"
android:layout_weight="0"
android:paddingLeft="10dp"
android:paddingRight="10dp"
android:scaleType="fitStart" />
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:orientation="vertical">
<TextView
android:id="#+id/file_row_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="16dp" />
<TextView
android:id="#+id/file_row_desc"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="12dp" />
</LinearLayout>
<ImageButton
android:scaleType="fitStart"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:layout_weight="0"
android:background="?android:selectableItemBackground"
android:onClick="showFilePopup"
android:src="#drawable/ic_more_vert" />
Studio preview shows dotted line. Is it responsible for the padding?
Add these 2 lines to your TextView:
android:height="16dp"
android:gravity="bottom|clip_vertical"
That will push the text to the top of it's view. If you want to have it actually touching the view above, you can reduce height.
Here are a couple of screenshots:
1st with height=16
And an exaggerated one with height=14
And here's a link to give you other various XML attributes for TextView

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.

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 a listview that consists three columns. The first one is an ImageView, the second and third one are textviews (see code blow).
I want the list to be aligned like this:
the icon and the date should always been shown completely !!
the text in the middle should show as much chars as possible
the date should always be on the right of the right side
With the XML below it looks ok on my Nexus 4. But on the asus tablet the date should be more on the right and the coloumn in the middle should show more text (screenshot 1). On the AVD (screenshot 2) the coloumn in the middle should be smaller and the date should be shown completely.
Can anyone tell me how to change the XML? Thanks!

Off the top of my head your layout would look something like 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="match_parent"
android:padding="5dp" >
<ImageView
android:id="#+id/logo"
android:layout_width="50dp"
android:layout_height="50dp"
android:layout_marginLeft="5dp"
android:layout_marginRight="20dp"
android:layout_marginTop="5dp"
android:src="#drawable/social_chat" />
<TextView
android:id="#+id/label"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#+id/label"
android:textAppearance="?android:attr/textAppearanceLarge"
android:layout_weight="1"
android:singleLine="true" />
<TextView
android:id="#+id/last_changed"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="15dp"
android:layout_marginLeft="5dp"
android:text="#+id/last_changed"
android:textAppearance="?android:attr/textAppearanceSmall"
android:singleLine="true" />
</LinearLayout>
The key here is to use wrap_content for the views that just need to keep their size, and set a weight for the middle view, which you want to fill the rest of the row.
Some useful tips.-
fill_parent is deprecated, use match_parent instead
When a view has no children, you can just close it with />
singleLine="true" is enough to have a singleLined TextView
You'll usually want to use dp units instead of px
This should do your job. I have put the imageview on the parents left, the date on the parents right and the label to the rightof image and to the left of date.It should work fine for you. Margins , padding please put yourself

I have a LinearLayout with three RelativeLayout inside. The first two children layouts show. The third one does not show. When I change the children from RelativeLayout to LinearLayouts, the third one still does not show. Any ideas on how to fix this? The one not showing contains the ImageView.
Here is the 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="60dp"

android:layout_alignParentRight="true"
android:src="#drawable/guess" />
</RelativeLayout>
</LinearLayout>
Your second Relative Layout's height is
android:layout_height="match_parent"
try putting:
android:layout_height="wrap_content"
--edit - try adding a weight attribute.
</RelativeLayout>
<RelativeLayout
android:weight=1
>
</RelativeLayout>
<RelativeLayout
android:weight=1>
</RelativeLayout>
android:layout_centerInParent="true" remove this from the view, if you want to add a view you can add separately out of the RelativeLayout with this your Layout is already in the center of the parent, For debug purpose set the width of each view to certain level so that you can see. Your two RelativeLayout already took the width of the Linear Layout, so no space left for the third Layout.
I decide to do it programmatically. I get the width of the device using context.getResources().getDisplayMetrics().widthPixels. Then from there I layout my pieces pixels by pixels, so to speak.
minimize the gap that I have between two TextViews (main text and subtext) that are in a linear layout and vertical. I tried to pad the subtext to the top, change the hight of the subtext and change the top margin but the gap remains, and I just get a row with an unnecessary hight. My XML is attached

this is a picture of what it should look like
but what I actually have is a big gap between IMDB and account
Your screenshot isn't showing up, but one thing you can try that's worked for me before is to set the bottom margin of your title and top margin of your subString to negative; i.e.
<TextView
android:id="#+id/txtTitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_marginBottom="-10dp"
android:textColor="#000000"
android:textSize="20sp" />
