I have a left-aligned TextView and a right-aligned button side-by-side. I want the button to take up as much space as it needs on the right (depending on the text that goes in it) and the left text to fill as much as it can and ellipsize on any overflow.
|Long title that may or may not ellipsi... <Button with text>|
I've read and tried lots of other posts that seem to have similar problems, none of which have worked for me. I've tried both using a LinearLayout with weights as well as a RelativeLayout with layout_toLeftOf assigned, none of which is resulting in what I need.
This is my LinearLayout code (with unnecessary parts taken out) where I give the left TextView a layout_weight of 1 and the button a layout_weight of 0. This should give the right-side button all the space it needs and give the TextView the rest, but instead the left title stops showing up and the right button gets smushed to the side and cut off. I've tried replacing the widths of both the Text and button to 0dip as I've seen suggested, which doesn't change anything.
<LinearLayout
android:layout_height="#dimen/title_bar_height"
android:layout_width="fill_parent"
android:orientation="horizontal">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:ellipsize="end"
android:layout_gravity="left|center_vertical"
android:gravity="left|center_vertical"
android:textSize="22sp"
android:lines="1"/>
<include layout="#layout/action_buttons"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="0"/>
</LinearLayout>
Replacing the layout_weight of the TextView with 0 actually allows the right-side button to properly fit on the screen fully, but the left text still does not show up. If I have both layout_weights set to 0 for the TextView and button and I then change the TextView's width from 0dip to wrap_content, everything shows up but the button instead is squished to fill the remaining space (and the text inside is truncated).
Here is my attempt with a RelativeLayout:
<RelativeLayout
android:layout_height="#dimen/title_bar_height"
android:layout_width="wrap_content">
<include layout="#layout/action_buttons"/>
<TextView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_gravity="center_vertical"
android:layout_alignParentLeft="true"
android:layout_toLeftOf="#layout/action_buttons"
android:gravity="center_vertical"
android:scaleType="center"
android:textSize="22sp"
android:ellipsize="end"
android:lines="1"/>
</RelativeLayout>
Everything aligns fine and shows up, except that the left TextView (when it's too long) overlaps and appears on top of the button rather than truncating and ellipsizing. Shouldn't android:layout_toLeftOf"#layout/action_buttons" specify that the TextView should stay to the left boundary of the button?
I've tried seemingly everything I can find on this site related to this issue, and I still can't get a solution. Any help would be greatly appreciated!
This will do the trick for you:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_gravity="left|center_vertical"
android:layout_weight="1"
android:ellipsize="end"
android:gravity="left|center_vertical"
android:singleLine="true"
android:text="Some really long textttttttttt tooooooooooo make the ellipsize work in the preview"
android:textSize="22sp" />
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button Text" />
</LinearLayout>
Here's what it looks like when run:
And again with a button with more text:

so I'm currently working on an app on Android, and I got stuck on a specific problem regarding the RelativeLayout, which I can't find a way to solve.
I have in the layout three views as follows: TextView, Textview and ImageView (laid horizontally), here is a screenshot of the ios counterpart:
the Textview at the middle should stick to the first one, until he gets to the Imageview, when he does, he keeps his minimum size (wrap content), while the first Textview truncate.
On IOS I setted priorities to the constraint to accomplish this, but I can't figure out how to solve this on Android.
Here what I tried:
<android.support.percent.PercentRelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:background="#drawable/daily_movie_title_box">
<TextView
android:id="#+id/daily_header_textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="15dp"
android:text="New Text aawi oa ioawfwi"
android:textSize="16sp"
android:textStyle="bold"
android:textColor="#color/white"
android:lines="1"
android:singleLine="true"
android:layout_alignParentStart="true"
/>
<TextView
android:id="#+id/duration_text"
android:text="138 mins"
android:layout_width="100dp"
android:layout_height="wrap_content"
android:textSize="13sp"
android:textColor="#color/white"
android:lines="1"
android:layout_alignBaseline="#id/daily_header_textview"
android:layout_toStartOf="#+id/certification_icon"
android:layout_toEndOf="#id/daily_header_textview"
/>
<ImageView
android:id="#id/certification_icon"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_alignParentEnd="true"
android:src="#drawable/uk12a"
android:layout_alignBottom="#id/daily_header_textview"
app:layout_aspectRatio="100%"/>
</android.support.percent.PercentRelativeLayout>
Which resulted in this (which is what I want):
But when I increase the first Textview text it's not behaving as I desire...
Is it possible to achieve the behaviour I want in Android (keep the middle Textview wrap content, and truncate the first one if needed)?
I will post an update if I find a solution eventually, just wanted to see if anyone can find an easy way to achieve this behaviour, as I suspect there is.
Thanks.
From my understanding, you want the first TextView to be as large as possible, without adding space after the text if the text is too small. The second TextView should only wrap_content, but it should fill the rest of the parent layout when the row doesn't. The ImageView is set to wrap_content.
I tested it with this layout:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<TableLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:shrinkColumns="0"
android:stretchColumns="1">
<TableRow>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:singleLine="true"
android:text="Shrinking text dddddddddddddddddddddd"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Midle column"/>
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#mipmap/ic_launcher"/>
</TableRow>
</TableLayout>
</LinearLayout>
The only problem is that if the second column has a incredibly large text, it will push the other views out of the parent. But in your case, I don't think that will be a problem. Otherwise, I think it does the job.
These are some suggested solutions:
You can use LinearLayout with horizontal orientation and weight for each component (TextViews and ImageView).
You can set the minimum and maximum text length for the second TextView.
But i prefer to apply the first solution. You can assign a weight for each component ( amount of space on the screen ) using:
android:layout_height
The situation is the same no matter if I use LinearLayout or RelativeLayout. I think this is a old Android XMl bug, but I have no idea why it still exists.
Namely, in a layout where an ImageView is on the right side of a TextView can disappear from the screen when text becomes too long. It simply pushes it off the screen. I must NOT make TextView single line.
Here is the XML.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<TextView
android:id="#+id/txt"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="some long text blahblahblahblahblah"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textSize="17sp"
android:layout_marginRight="10dp"
android:layout_centerVertical="true"
/>
<ImageView
android:layout_toRightOf="#+id/txt"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/key"
android:layout_centerVertical="true"
/>
</RelativeLayout>
I cannot use layout_weight attribute as image will then stick to the right side of the screen. It HAS to be on the right side of the text.
Anyone has any ideas how to solve this bug?
Check images when the text is short and long. On the 2nd image the text is long and the image is being pushed away from the screen.
You can achieve your task, if you use the layout_weight properly. Please refer the code below:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:orientation="horizontal"
>
<TextView
android:id="#+id/txt"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="The quick brown fox jumps over the lazy dog. As you can see it easily handles the long length of the text"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textSize="17sp"
android:layout_marginRight="10dp"
/>
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_launcher"
/>
</LinearLayout>
The output for long text:
The output for short text:
EDIT:
This works because of the layout whose width is set as wrap_content. If it were match_parent then in all cases, all the extra space would have been given to TextView because of it's layout_weight but since the parent is wrap_content, there is no extra space for the TextView to fill when the text is small. But when the text is large, the weight property is applied to the TextView but since there is no layout_weight for the ImageView hence, it takes only the amount of space it has to.
Set
android:layout_marginRight="30dp"
for the TextView
and
android:layout_marginLeft="-20dp"
for the ImageView
You can change the values depending on your needs.
But, if the image can have different sizes, you will have to set margins programmatically.
there is 2 solutions for these
either set the image as a drawableRight to the textview
<TextView
android:id="#+id/txt"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="The quick brown fox jumps over the lazy dog. As you can see it easily handles the long length of the text"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textSize="17sp"
android:layout_marginRight="10dp"
android:drawableRight="#drawable/ic_launcher"
/>
or
alignt the image to right and make textview toleft of the image
I am wondering how to have a TextView display its content on several lines without hardcoding the width in the XML.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="right"
android:orientation="horizontal">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:singleLine="false"
android:text="Long multiline text"/>
<TextView
android:textColor="#color/text_color"
android:layout_width="130dp"
android:layout_height="wrap_content"
/>
</LinearLayout>
Any thought welcome.
EDIT: my problem is that when the text exceeds the width set (because it reaches the end of the screen) a portion of the text is just not displayed. I would expect the text to be split on two lines
Though I cannot reproduce the not wrapping problem, you can fix the positioning problem by using a weight on the first TextView. Using the following XML gives the expected output in the graphical layout view in Eclipse:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="right"
android:orientation="horizontal">
<TextView
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:singleLine="false"
android:text="Long multiline text"/>
<TextView
android:textColor="#color/text_color"
android:layout_width="130dp"
android:layout_height="wrap_content"
/>
</LinearLayout>
Also add
android:minLines="2"
android:scrollHorizontally="false"
You could try
android:inputType="textMultiLine"
in your TextView XML. This worked for me.
I think I had very similar problem. I had a TextView with a text, where I was not sure how much lines will it take. It was encapsulated by a LinearLayout having android:layout_width="match_parent" to ensure my text will fill out all the space horizontally. However, the problem was that my text did not fit into 1 line and when it did break into a new line, the next view component below it did not move downwards to give enough space for the second line to be viewable fully.
I could achieve the solution by changing the LinearLayout that was containing my TextView into a RelativeLayout. By this way, the element below the text (actually below the Layout itself) was moved automatically to give enough space for the multi-line text.
I have an activity with two Buttons and a TextView in a LinearLayout. My TextView is offset downwards and the text doesn't fit inside the box. Can you explain what is happening? I think it is related to padding, and I've read several discussions about the perils of TextView padding, but that doesn't explain why the text is cut off at the bottom.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"

<Button
android:text="This"
android:background="#drawable/button_red"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
<Button
android:text="That"
android:background="#drawable/button_green"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
<TextView
android:text="Copious amounts of text that overflows onto several lines on a small screen, causing the TextView to dangle below the buttons. Why it does this I can't imagine. I only hope someone can help me with this."
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#533f93"
/>
</LinearLayout>
This code produces this display:
The purple is the LinearLayout, the blue is the TextView. As you can see, the TextView's top is below those of the buttons and its bottom is below the bottom of the LinearLayout. As I add text to the TextView, the LinearLayout increases its height appropriately, but because the TextView is offset, I always lose the bottom of the last line.
I ran Hierarchy Viewer and it gave me this wireframe:
Which shows the vertical offset at the top, but misses the bottom of the TextView. The same wireframe with the LinearLayout selected looks like this:
According to Hierarchy Viewer, the top of the buttons is at 0, but the top of the TextView is at 7. I've tried various fixes, mostly culled from this site:
android:paddingTop="0dp"
android:background="#null"
android:includeFontPadding="false"
None of these fixed my issue.
Set android:baselineAligned property of your LinearLayout to false.
From documentation:
When set to false, prevents the layout from aligning its children's
baselines. This attribute is particularly useful when the children use
different values for gravity. The default value is true.
give the layout_gravity of the Textview to be center_vertical
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

<Button
android:text="This"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
<Button
android:text="That"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
<TextView
android:text="Copious amounts of text that overflows onto several lines on a small screen, causing the TextView to dangle below the buttons. Why it does this I can't imagine. I only hope someone can help me with this."
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#533f93"
android:layout_gravity="center_vertical"/>
</LinearLayout>
Try setting the layout_gravity for the TextView like this:
<TextView
android:text="Copious amounts of text that overflows onto several lines on a small screen, causing the TextView to dangle below the buttons. Why it does this I can't imagine. I only hope someone can help me with this."
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#533f93"
android:layout_gravity="top"
/>
If you have this problem with several TextViews you can add android:gravity="center_vertical" to LinearLayout
I'm still a bit of an Android noob, forgive me if this is simple and I'm just not seeing it.
There are two portions of text in a view that spans the entire width horizontally, but is only as high as one line of text. The left side must always be displayed in full, but should take no more horizontal space than it needs. The right side should be pushed over by the left side and fill up the remainder of the screen width. If the right side text is smaller than this width, the text should be right-aligned horizontally. If the text is greater than the width, it should scroll horizontally.
The text on the right side will be updated frequently and should slide up with new text when the app tells it (explaining the TextSwitcher in the layout).
I have tried two different layout styles. In both situations, I can get the left side to "push" the layout, the right side to scroll, but I can't figure out how to get the right side to right align. It is always left aligned. Here is a picture showing what is happening...
http://img10.imageshack.us/img10/5599/androidlayout.png
In addition (but less important), in my layout code I have android:fadingEdge="none" on the TextViews, but it still has a faded edge on the left and right side when it scrolls. Why is that?
Here are the two layouts I created, which yield the results shown, but not the results I want.
Using a horizontal LinearLayout...
<?xml version="1.0" encoding="utf-8"?>

</LinearLayout>
So how do I get that text on the right side to right-align. Thanks!
EDIT:
I found the problem... There were a few things wrong. First, I discovered the difference between gravity and layout_gravity. I needed to use gravity to right-align the text.
I can't add any more links, so copy and paste the link below
thinkandroid.wordpress.com/2010/01/14/how-to-position-views-properly-in-layouts/
However, that didn't give me exactly the layout I wanted, because long lines of text will be right-aligned before scrolling and the front part of the message cannot be read until it loops around. What I needed to do was use three "columns" of views, with the weight on the middle (empty) view to be "1" while the others "0" so that it pushes the right-most text as far as possible to the right, while still maintaining left-alignment.
Next, I discovered that the width of a TextSwitcher is the same as the largest child TextView. This is a problem when switching from a long line to a short line using setText() because the middle column won't push the small text over to the edge. The solution is to use two setText()s. One to cause the fade-out animation, then push a runnable to run after the animation to set the text again to cause the fade-in animation of the new line.
Now my only problem is that when the fade-out animation runs on a long line of text, if it is in mid-scroll, it resets to the X=0 position before fading, so the effect is that it scrolls, jumps to the origin position, then fades out. Anybody know how to fix that?
(I removed the RelativeLayout code above since that was wrong, since this post is really long.)

Unfortunately, horizontally scrolling the text looks terrible when the text switches every five to ten seconds. So I'm just letting it run off the screen.
