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 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:
I have a ListView that displays a bunch of homework assignments. The ListView items use a FrameLayout to position two TextViews. The first TextView is aligned to the left, and the second is aligned to the right. (Both are aligned in the center vertically.) The first displays a snippet of the assignment description, and the second displays the due date.
What I want to do is make it so that the due date takes up as much space as it needs and the description fills up the remaining space, like so:
|----------------------------------------------------|
| Read pgs 15-35, update tim... Fri, May 4|
|----------------------------------------------------|
Right now the description text will continue on to overlap the date. It will truncate at the end of the line though.
Is there anyway I can do this in XML, or do I have to do it in code by shortening the string before I set the TextView value (presumably in my getView call)? If I did it in code, I'd have to calculate the amount of horizontal space the strings would take up figure out how short the description needs to be. That seems like it could get messy...
Any other suggestions on how to accomplish this are greatly appreciated!
Try using the ellipsize attribute like :
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ellipsize="end"
android:singleLine="true"/>
Note that Android, or at least some versions, require both the "ellipsize" and the "singleline" attributes in order for the system to actually do the truncation and add the ellipsis.
Instead of a FrameLayout, this is the perfect place for a LinearLayout or RelativeLayout in combination with ellipsize:
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<TextView
...
android:width="0dp"
android:height="wrap_content"
android:layout_weight="1"
android:ellipsize="end" />
<TextView
...
android:width="wrap_content"
android:height="wrap_content"
android:layout_weight="0" />
</LinearLayout>
Or alternately
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<TextView
...
android:id="#+id/secondTV"
android:width="wrap_content"
android:height="wrap_content"
android:layout_weight="0" />
<TextView
...
android:width="0dp"
android:height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_toLeftOf="#id/secondTV"
android:ellipsize="end"/>
</RelativeLayout>
Change the FrameLayout to a LinearLayout or RelativeLayout.
LinearLayout: Make the due date width "wrap_content" and the description width 0dp, then add layout_weight="1" to the description
RelativeLayout: Layout the due date first with width wrap_content, then layout the description with a rule that it should be to the left of the due date.
Both Anton and JRaymond were pretty much on (JRaymond helped me figure it out with his example). This is what I came up with:
<RelativeLayout android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView android:id="#+id/due_date"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_alignParentRight="true"
android:singleLine="true" />
<TextView android:id="#+id/description"
android:layout_width="0dp"
android:layout_height="fill_parent"
android:layout_alignParentLeft="true"
android:layout_toLeftOf="#id/due_date"
android:singleLine="true" />
</RelativeLayout>
(I needed to declare my due date label first so that I could reference it in the description. I also just realized that the android:ellipsize seems to be optional -- I guess it defaults to "end".)
Thanks a bunch!
Can anyone tell me what's going wrong with the text? Text longer than one line doesn't wrap to the next line but goes beyond the screen.
Following is the code:

The only correct answer to this question is that you need to set the parents to a proper width (in this case FILL_PARENT, WRAP_CONTENT) and use android:layout_weight=1 for the textview that needs to be wrapped.
SingleLine is on by default so that won't make any changes.
A width set to 0px will work but is not a good solution.
Some example (in a tableview this time), using xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:orientation="vertical">
<TableLayout android:layout_width="fill_parent"
android:layout_height="wrap_content" android:stretchColumns="*"
android:id="#+id/tableLayout1">
<TableRow android:id="#+id/tableRow1" android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView android:text="test1" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:layout_weight="0" />
<TextView android:layout_weight="1"
android:text="test2 very long text that needs to be wrapped properly using layout_weight property and ignoring singleline since that is set by default..."
android:layout_width="fill_parent" android:layout_height="wrap_content" />
</TableRow>
</TableLayout>
</LinearLayout>
If you want to set this in code you're looking for the layout_weight as a third parameter as in this example where it is set to 1:
row.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
TextView label = new TextView(getApplicationContext());
label.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT, 1f));
You must use 2 parameters :
android:ellipsize="none" : the text is not cut on textview width
android:scrollHorizontally="false" the text wraps on as many lines as necessary
It is enough to use in your xml file.
android:singleLine="false".
Hope it will work.
All the best!
I could not get any of these solutions working when using a TableLayout>TableRow>TextView. I then found TableLayout.shrinkColumns="*". The only other solution that worked was forcing the TextView to layout_width:250px etc but i don't like forcing widths like that.
Try something like this if working with tables.
<TableLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:shrinkColumns="*">
Note you need shrinkColumns="*"
This is obviously within a <LinearLayout>. So something like <LinearLayout> <TableLayout> <TableRow> <TextView>
references:
TableLayout

Hope that helps someone.
One of your layout parameters is wrong in your code. In the first TextView
android:layout_width="wrap_content"
change to
android:layout_width="fill_parent"
The text that out of screen width size will wrap to next line and set android:singleline="false".
Set the height of the text view android:minHeight="some pixes" or android:width="some pixels". It will solve the problem.
For my case removing input type did the trick, i was using android:inputType="textPostalAddress" due to that my textview was sticked to one line and was not wrapping, removing this fixed the issue.
I'm an Android (and GUI) beginner, but have lots of experience with software. I've gone through a few of the tutorials, and this is my understanding:
layout_width and layout_height are attributes of the TextView. They are instructions for how the TextView should shape itself, they aren't referring to how to handle the content within the TextView.
If you use "fill_parent", you are saying that the TextView should shape itself relative to it's parent view, it should fill it.
If you use "wrap_content", you are saying that you should ignore the parent view, and let the contents of the TextView define it's shape.
I think this is the confusing point. "wrap_content" isn't telling the TextView how to manage it's contents (to wrap the lines), it's telling it that it should shape itself relative to it's contents. In this case, with no new line characters, it shapes itself so that all the text is on a single line (which unfortunately is overflowing the parent).
I think you want it to fill the parent horizontally, and to wrap it's contents vertically.
Even-though this is an old thread, i'd like to share my experience as it helped me. My application was working fine for OS 2.0 & 4.0+ but for a HTC phone running OS 3.x the text was not wrapping. What worked for me was to include both of these tags.
android:maxLines="100"
android:scrollHorizontally="false"
If you eliminate either it was not working for only the os 3.0 device. "ellipsize" parameter had neutral effect. Here is the full textview tag below
<TextView
android:id="#+id/cell_description"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingTop="5dp"
android:maxLines="100"
android:scrollHorizontally="false"
android:textStyle="normal"
android:textSize="11sp"
android:textColor="#color/listcell_detail"/>
Hope this would help someone.
Increase the height i.e.. android:height="Some size" , it is working fine for me.
I had a similar problem where were my two horizontally weighted TextViews didn't wrap the text. I later found out that the issue was because my viewparents parent had wrap_content instead of match_parent.
I think it depends on the particular combination of layouts in your display. Some flags may get overridden or ignored. I have a TabHost with tabs, each tab is a list of tables. So it is a tab of ListView, each row being a TableLayout of TextView. I tried the fixes listed above and none of them worked.
I know, that in question it is correct, but in my case, the problem was in setting textSize property in 'dp' - I've changed it to 'sp' and it works fine.
In my case, with a TableRow > ScrollView > TextView nesting, I solved the problem by setting android:layout_width to fill_parent on TableRow, and to wrap_content on ScrollView and TextView.
you have to use android:singleLine="false" in ur TextView tags.
I finally managed to add some pixels to the height of the TextView to solve this issue.
First you need to actually get the height of the TextView. It's not straightforward because it's 0 before it's already painted.
Add this code to onCreate:
mReceiveInfoTextView = (TextView) findViewById(R.id.receive_info_txt);
if (mReceiveInfoTextView != null) {
final ViewTreeObserver observer = mReceiveInfoTextView.getViewTreeObserver();
observer.addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
#Override
public void onGlobalLayout() {
int height = mReceiveInfoTextView.getHeight();
int addHeight = getResources().getDimensionPixelSize(R.dimen.view_add_height);
mReceiveInfoTextView.setHeight(height + addHeight);
// Remove the listener if possible
ViewTreeObserver viewTreeObserver = mReceiveInfoTextView.getViewTreeObserver();
if (viewTreeObserver.isAlive()) {
viewTreeObserver.removeOnGlobalLayoutListener(this);
}
}
});
}
You need to add this line to dimens.xml
<dimen name="view_add_height">10dp</dimen>
Hope it helps.
I just removed android:lines="1" and added android:maxLines="2", this got the text to wrap automatically. The problem was the android:lines attribute. That causes the text wrapping to not happen.
I didnt have to use maxEms or singleLine="false" (deprecated API) to fix this.
I've spent hours to figure out that in the text I was trying to display contained a single quote (in string.xml) so I just escaped it with a backslash and it worked nicely => the height of the TextView was correctly wrapping text:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:paddingLeft="16dp"
android:paddingRight="16dp"
android:paddingTop="16dp"
tools:context=".MainActivity">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fontFamily="sans-serif-smallcaps"
android:text="#string/instructions"
android:textAlignment="center"
android:textSize="18sp"
android:textStyle="bold" />
<EditText
android:id="#+id/keyword"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/defaultKeyword"
android:textSize="22sp"
/>
I'm using constraint layout mostly.
1) android:layout_width="match_parent" = tries to stretch to meet edges
2) android:layout_width="wrap_content" = based solely on the input text without regard for other views nearby. for example adding android:textAlignment="center" will change the shape of the text
3) android:padding="12dp"
android:layout_width="0dp"
android:layout_weight="1"
android:singleLine="false"
= The text will fold to accommodate nearby layouts without regard to the text itself
In my case, My text view has a background, so applying width as 0dp does not work for me, because even for small texts the background will take the whole available space. Managed to solve it by adding
app:layout_constrainedWidth="true"
no need to set the width as 0dp, wrap content is working fine, hope this helps someone with same issue
inside your TextView write this:
android:inputType="textMultiLine"
problem solved
I put this attribute:
android:inputType="textMultiLine"
into my TextView and it has wrapping line and user can "Enter" for a new line.
============================================================
When you come to this post, you may want to create a Big TextView which can display multiple lines so these attributes may also needed
android:layout_height="Xdp" //where X is a number depends on how big Textview you want
android:gravity="top" //in order to make your text start from the top of your TextView.
I used android:ems="23" to solve my problem. Just replace 23 with the best value in your case.
<TextView
android:id="#+id/msg"
android:ems="23"
android:text="ab ab ab ab ab ab ab ab ab ab ab ab ab ab ab ab ab ab ab ab ab ab ab ab ab ab ab ab ab "
android:textColor="#color/white"
android:textStyle="bold"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
I added a \n in the middle of my string and it looked okay.
To wrap the text and to put the text in next line we sholud use the "\n" i.e new line character in the layout xml file and check tht change on the emulator not on the layout screen.
