Prevent auto Line Break in Multi lines TextView - android

I know this question has been ask several times but maybe not exactly for this requirement.
I want to create a log view, so currently based on a TextView and obviously, like in all log views, in AS's logcat for example, I will have several lines so I can enable vertical scrollbar and I can have long log lines, each line terminated by a \n.
Here I hoped that horizontal scrollbar could help me. But it seems not, right?
If not, how to do?
EDIT my current Textview definition:
<TextView
android:id="#+id/tvLog"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="8dp"
android:background="#android:color/darker_gray"
android:ems="10"
android:gravity="fill_horizontal"
android:inputType="none"
android:lines="5"
android:maxLines="20"
android:scrollbars="horizontal|vertical"
android:singleLine="false"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/elvTests" />

as i have understood that you want all text to be displayed and that you can scroll it downwards so based on that i guess you can do something like this
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/long_text"/>
</ScrollView>
putting your text view in a scroll view that matches its parent in width and height and a text view with wrap_content will enable this behavior hope this helps
EDIT
put this in your code that should do the work
TextView textview= (TextView) findViewById(R.id.your_textview_id);
textview.setMovementMethod(new ScrollingMovementMethod());

TextView in HorizontalScrollView not scrolling automatically when text is added

I have a TextView that takes in Strings and I want the TextView to scroll to the last text added on the right automatically. The ScrollView works but I have to scroll manually to the last text added when it's out of the TextView's field of view. Please help.
<HorizontalScrollView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1.5"
android:fillViewport="true"
android:scrollbars="none">
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right"
android:scrollHorizontally="true"
android:textColor="#android:color/black"
android:textSize="24sp" />
</HorizontalScrollView>
yourScrollView.fullScroll(HorizontalScrollView.FOCUS_RIGHT);
I solved this problem through the use EditTextView instead of TextView and disabling focusEnabled by setting keyListener to null in order to achieve the behavior of a normal TextView and also scroll automatically like I wanted.

Avoid TextView resizing if text is too long

I have a TextView that when it has a long text, it resizes to make the text fit inside, breaking the UI.
Is there a way to use a XML attribute to make the TextView not resizable?
I was thinking about using the TextView inside a ScrollView, is there other options?
For this to work, set specific width to textview (It will display textview without scroll)
android:layout_width=""
If you want to show scroll, add scrollview with specific size and inside scroll layout, add textview like
<ScrollView
android:layout_width="100dp"
android:layout_height="100dp"
android:id="#+id/scrollView"
android:fillViewport="false">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</ScrollView>
100dp is dummy size here.
Solution :
<TextView
android:elipsize="marquee"
</TextView>
check out this Answer for more options :
Elipsize Examples
this will slide the textView
Try this code:
<TextView
android:layout_width="100dp"
android:layout_height="wrap_content"
android:singleLine="false"
android:singleLine="false"
android:text="Long multiline text"/>

Horizontally Scrollable TextView show inconsistent behaviour across android versions

I have a text view that has a single lined Arabic (Right-to-Left) text. The Text content increases by time, and the last (left-most) part should always appear. The horizontal scroll bar is initially set to right, and auto scrolls to left as text increases.
The below code works great on a 2.3 Android phone.
This comes from the layout.xml
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ellipsize="none"
android:fadingEdge="horizontal"
android:gravity="right"
android:scrollHorizontally="true"
android:scrollbars="horizontal"
android:singleLine="true"
android:text="#string/txt_start"
android:textAppearance="?android:attr/textAppearanceLarge" />
I have this in the onCreate() method of my Activity
tv = (TextView) findViewById(R.id.textView1);
tv.setMovementMethod(new ScrollingMovementMethod());
The problem is the inconsistent behaviour of the text view on phones having android 4.0+ . The horizontal scroll bar is initially no placed on the right, so the TextView is initially blanked! If I try to scroll the blank textView, the text shows up. When extra text is added, the scroll-bar is not scrolled to show the new text, but if I manually scrolled the text, it appears.
I searched stackoverflow, and tried to add the below properties with no success.
android:focusable="true"
android:focusableInTouchMode="true"
None of those solutions worked in my case where I wanted to animate scrolling of TextView with android:gravity="right". Simple workaround that helped though is to keep TextView gravity to left but place it aligned to right inside a RelativeLayout container:
<RelativeLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<AutoScrollingTextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:gravity="left"
android:singleLine="true"
android:ellipsize="none">
</RelativeLayout>
Try this example, it should work:
<?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="fill_parent"
android:orientation="vertical" >
<TextView
android:id="#+id/myText"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/myscroll"
android:ellipsize="marquee"
android:singleLine="true"
android:scrollHorizontally="true"
android:marqueeRepeatLimit="10"
>
</LinearLayout>
Note: when testing the marquee, don't test it in design view inside Eclipse, try it on the emulator\device ..
Also if you want to add a scrolling effect in code:
TextView tView = (TextView) findViewById(R.id.myText);
tView.stSelected(true);
To make the marquee scroll non-stopping on the end of marquee:
android:marqueeRepeatLimit=”marquee_forever”
It's found that the gravity Left/Right are deprecated, a developer should use Start/End. For the text to scroll it needs a "wrap_content" set to its width, additionally the textDirection needs to be set to RTL. For unknown reasons, textDirection did not work programmatically, but worked in the xml.
This code works well on all API versions of android.
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="end"
android:textDirection="rtl"
android:scrollHorizontally="true"
android:scrollbars="horizontal"
android:singleLine="true"
android:ellipsize="none"
android:text="#string/txt_start"
android:textAppearance="?android:attr/textAppearanceLarge" />

Multiline TextView with width "wrap_content"

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.

Android TextView Text not getting wrapped

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">
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
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">
<TextView
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:id="#+id/reviewItemDescription"
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"
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:padding="4dip"
android:layout_weight="1">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:padding="4dip">
<TextView
android:id="#+id/reviewItemEntityName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
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" />
</LinearLayout>
<TextView
android:id="#+id/reviewItemDescription"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textSize="12sp"
android:width="0dip" />
</LinearLayout>
<ImageView
android:id="#+id/widget01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/arrow_nxt"
android:layout_gravity="center_vertical"
android:paddingRight="5dip" />
</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.
