Word splitting in TextView

I'm using TextView to show some messages in my app. The messages contains some HTML tags so I'm using textView.setText(Html.fromHtml(message)). But there is an issue with this. Concrete words splitting in to two lines as shown below.
I need the words to not split and behave like it does with textView.setText(message).
TextView definition:
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="#dimen/padding"
android:layout_marginTop="#dimen/marginTop"
android:layout_marginBottom="#dimen/marginBottom"
android:layout_marginLeft="0dp"
android:layout_marginRight="#dimen/marginRight"
android:gravity="left"
android:shadowColor="#color/textShadow"
android:shadowDx="1"
android:shadowDy="1"
android:text="msg"
android:textColor="#android:color/black"
android:textColorLink="#android:color/black"
android:background="#drawable/background"
android:textSize="#dimen/textSize" />

You are intentionally telling Android to not split across words, by using a non-breaking space ( ). Replace those with actual spaces.

android:singleLine="true"
is the property of textview and edittext which will keep the text on single line. if length of string is too big then text will be truncated but will never go on next line.
If possible can you pl add your message value i.e. the html you are passing to Html.fromHtml.

Android - TextView ellipsize doesn't work properly

Android ellipsize doesn't work as expected in some cases.
What I'm expecting is three dots on the last line, but in cases it adds the 3 lines plus a few characters related to the rest of the text afterward. Is it possible to change this behavior?
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="left"
android:singleLine="false"
android:ellipsize="end"
android:maxLines="2"
android:layout_marginBottom="16dp"/>

According to me android:ellipsize="end" depends on the words in the TextView.
If following word is lengthy then it omits the word and shows ...
If the following word is small then it will fit correctly and last fill ...
Hope it helps.

Android TextView doesn't do linebreak in ListView (multiline text)

I have created a 3-level ExpandableListView and have the problem that the TextViews which are used for the 2nd and 3rd level do not support line-breaks if the content is too long. It should be dynamically over more than one line, if needed. The 1st level TextView does it well (automatically) and I actually had the same settings in the xml for all three TextViews. Followed are the layout xmls, the one TextView with the id groupname is for the 2nd level (e.g. the first red X in the picture below) and the one with id childname is for the 3rd level (e.g. the second and third red X in the picture below). It should all be like at the green hook in the picture.
"singleLine=false" seems not to work. Also tried some different options found in other SO posts, but what I've testet haven't worked for me. Like ellipsize, scroll horizontale, different layout_width and so on. The only thing worked is to set a fixed layout_width on x hundred dp, but this is not dynamically, I'm right?
Would be great if anybody could help me with this. Lot of thanks!
Here's a screenshot:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="match_parent" >
<TextView
android:id="#+id/childname"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginRight="60dp"
android:layout_marginLeft="60dp"
android:textColor="#AAAAAA"
android:singleLine="false"
android:text=""
android:gravity="center_vertical"
android:textAppearance="?android:attr/textAppearanceMedium" />
<TextView
android:id="#+id/groupname"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_marginLeft="45dp"
android:layout_marginRight="60dp"
android:textColor="#555555"
android:singleLine="false"
android:gravity="center_vertical"
android:text=""
android:textAppearance="?android:attr/textAppearanceMedium" />

Add this line in your xml
android:inputType="textMultiLine"
or
Add text using coding like this, where you can add line break using '\n'(But here you have to manually add breaks where you want them)
TextView txt1 = (TextView) findViewById(R.id.childname);
txt1.setText("Hi \nHello \nHow are You");
Results will be
Hi
Hello
How are You
Edit
Accepted Answer - removing the line 'android:layout_alignParentLeft="true"

try using LinearLayout instead of RelativeLayout as parent for the TextView

I had add this attribute to my TextView inside ListView, and makes it do line break correct.
android:maxWidth="xxxdp"
F.Y.R.

Android - Is it possible to overlay text on text?

I want to create special characters for math, for an android application. And I wonder if it's is possible to overlay one character on top of another, or if there is some fine control on how text is rendered (and how do you go about doing that).

If you need a general method to display math equations, have a look at jqMath. I think you can render it using a WebView.
Many math symbols have Unicode code points. Specifically, the Unicode code point for the symbol of a '+' inside a circle is U+2295. They can be rendered directly if the font supports it. For a list of some math symbols with corresponding Unicode code points check this Wikipedia article.
Also have a look at this question for resources using MathML in Java.

I would extend the View class and then use the drawText method of the Canvas object you receive in the onDraw method. It sounds like you need fine control over coordinates of where text is being painted and extending View would give you just that. Take a look at Canvas.drawText and you can use the x and y coordinates to overlay text as you require.

Try this:
This way you can add Superscript text :
TextView out_unit2 = (TextView) findViewById(R.id.out_unit2);
out_unit2.setText((Html.fromHtml("meter<sup><small>2</small></sup>")));
Subscript text :
TextView out_unit2 = (TextView) findViewById(R.id.out_unit2);
out_unit2.setText((Html.fromHtml("meter<sub><small>2</small></sub>")));
You can use this to add as many to your code.
Hope it helps you.
Thanks.

It could get really messy really quickly, but you would be able to accomplish it with a FrameLayout and several TextViews inside. For example, XML for a "0" overlapped with a "+", superscript "+" and subscript "-":
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="0"
android:textSize="#dimen/title_bar_font_size" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="+"
android:textSize="#dimen/title_bar_font_size" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="+"
android:textSize="12sp"
android:layout_marginLeft="12sp" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="-"
android:textSize="12sp"
android:layout_marginLeft="12sp"
android:layout_gravity="bottom" />
</FrameLayout>
Resulting in:

Still have some issue? I can update question more.

Quoting myself from one of my books:
Android's TextView class has the built-in ability to "ellipsize" text,
truncating it and adding an ellipsis if the text is longer than the available
space. You can use this via the android:ellipsize attribute, for example.
This works fairly well, at least for single-line text.
The ellipsis that Android uses is not three periods. Rather it uses an actual
ellipsis character, where the three dots are contained in a single glyph.
Hence, any font that you use that you also use the "ellipsizing" feature will
need the ellipsis glyph.
Beyond that, though, Android pads out the string that gets rendered on-screen, such that the length (in characters) is the same before and after
"ellipsizing". To make this work, Android replaces one character with the
ellipsis, and replaces all other removed characters with the Unicode
character 'ZERO WIDTH NO-BREAK SPACE' (U+FEFF). This means the
"extra" characters after the ellipsis do not take up any visible space on
screen, yet they can be part of the string.
However, this means any custom fonts you use for TextView widgets that
you use with android:ellipsize must also support this special Unicode
character. Not all fonts do, and you will get artifacts in the on-screen
representation of your shortened strings if your font lacks this character
(e.g., rogue X's appear at the end of the line).

I have bumped into the same problem when was trying to use custom "MetaPro-Medium.otf" as font for TextView with a
android:singleLine="true".
The box at the end of the string was really annoying.
I found no way how to solve this problem in Android, but at the same time found following work around.
I have installed "FontLab Studio v5.04"
Opened my font
Selected one of symbols I was not going to use
Menu->Glyph->Rename Glyph
Changed the name and unicode index from it`s original value to "FEFF" (Thank CommonsWare)
Double click on selected symbol and then remove all lines this symbol was created from.
Menu->File->Generate Font->save as type otf
As a result I got updated font and problem gone away.

Arslan, your layout is working fine in my case, I have tested the same with:
<TextView
android:id="#+id/row_title"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:singleLine="true"
android:textSize="18sp"
android:ellipsize="end"
android:maxLines="1"
android:text="This is the demo testing demo testing This is the demo testing demo testing"/>
... and getting the exact output as you want "one line ended with ..." and box should be removed. So I think there may be a something wrong with any character or text you are setting.

I face the same issue (show boxes([])) for some special symbols when I try to show content which is coming from webservice url even, I don't use android:ellipsize. then I replace code from
textview.settext(content);
to
textview.settext(Html.fromHtml(content));
working fine.

Actually I was running into this issue and instead of changing the font or using setText I just added scrollHorizontally as false and it fixed the extra box character
android:singleLine="true"
android:scrollHorizontally="false"
android:ellipsize="end"

There was a similar problem which i was facing in my project where in i was using a font type for the text view. few font types have these problem of making the ... appear as [] at the last. The problem would be solved if u try changing the font.
