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 a LinearLayout that has four views layed out horizontally. The first and last component are a set size. For the inner two views I want to just share the available space 50:50. I set each to a weight of "1" but when the views are layed out, the views are different sizes depending on the content they hold.
Here is my layout xml for reference.
<?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">
<ImageView
android:id="#+id/status"
android:src="#drawable/white"
android:paddingRight="10dip"
android:layout_height="35dip"
android:layout_width="35dip">
</ImageView>
<TextView android:id="#+id/name"
android:text="Name"
android:layout_height="fill_parent"
android:layout_toRightOf="#id/status"
android:layout_width="wrap_content"
android:layout_weight="1"
android:textSize="25dip">
</TextView>
<TextView android:id="#+id/description"
android:text="Description"
android:layout_toRightOf="#id/name"
android:layout_height="fill_parent"
android:layout_width="wrap_content"
android:layout_weight="1"
android:textSize="25dip">
</TextView>
<TextView android:id="#+id/time"
android:text="Time"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_toRightOf="#id/description"
android:textSize="25dip">
</TextView>
</LinearLayout>
Obviously these aren't the actual column names but I changed them for privacy purposes. This layout is used by a ListView which changes the text of each view to be whatever value its presented. The name and description fields should line up since they're both given 50% of the remaining screen but when the name is longer the description is shifted right. Why?
For the weight to be considered, the layout dimension needs to be 0 (zero)
<TextView android:id="#+id/name"
android:text="Name"
android:layout_height="fill_parent"
android:layout_width="0dip"
android:layout_weight="1"
android:textSize="25dip">
</TextView>
I also recommend making your weight add up to either 1 (and use fractions) or 100.
So instead of 1 you would use either 50 or .5 for each view. The LinearLayout code will work properly with any weight sum, but it gets difficult if you want to modify your view later with additional sections.
Also, if you are not using relative layout, get rid of the toRightOf attributes. Less is more.
Try to use android:layout_width="fill_parent" instead of "wrap_content" in all children of LinearLayout. Or better yet, make such a structure in your xml:
<RelativeLayout>
<ImageView /> # status, fixed width, alignParentLeft="true"
<TextView /> # time, fixed width, alignParentRight="true"
<LinearLayout> # layout_width="fill_parent", toLeftOf="time" toRightOf="status"
<TextView /> # name, use layout_weight="1"
<TextView /> # description, use layout_weight="1"
</LinearLayout>
</RelativeLayout>
This should do what you want. Using LinearLayout instead of RelativeLayout might work too, but you have to experiment a bit (I believe using nested Layout, as in my example, will do the work).
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:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:padding="4dip">

android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:padding="4dip">
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:padding="4dip">

android:id="#+id/reviewItemEntityName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="event/venue"
android:textColor="#color/maroon"
android:singleLine="true"
android:ellipsize="end"
android:textSize="14sp"
android:textStyle="bold"
android:layout_weight="1" />
<ImageView
android:id="#+id/reviewItemStarRating"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_alignParentBottom="true"
android:src="#drawable/title_1_star" />
</LinearLayout>
<TextView

android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Description comes here"
android:textSize="12sp"
android:layout_weight="1"/>
</LinearLayout>
</LinearLayout>
I fixed it myself, the key is android:width="0dip"

android:layout_height="wrap_content"

android:padding="4dip"
android:layout_weight="1">

</LinearLayout>
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>

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.
