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"

I am currently working on an app and my layout is as follows:
I have a recyclerview holding all of my items, each item has a textview above an imageview. So the text view can expand up to 3 lines but only if needed. The recyclerview is using a gridlayout manager to display all of my items.
The problem is that currently when the text view expands to have more than 1 line it presses down the image instead of keeping it aligned with the other images in the row
What I currently have
What I want is to prevent the text view from pressing down on the image but instead build it's way up so that way the images stay normal and the text view will grow upwards like the image below.
What I want
Is there any way to achieve this? I would think it shouldn't be hard but I can't seem to find a way to accomplish this, or more likely, can't google the right terms to find the solution I'm looking for.
So I found an answer, I had to set two properties for my textview:
android:lines="3"
android:gravity="bottom"
so in the end each item had a layout below:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:paddingStart="31dp"
android:paddingEnd="32dp">
<TextView
android:id="#+id/app_name"
android:layout_width="#dimen/product_list_image_dimensions"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:text="#string/app_card_temp_name"
android:textSize="#dimen/product_list_text_size"
android:fontFamily="sans-serif-condensed"
android:lines="3"
android:textAlignment="center"
android:textColor="#color/app_name_product_list_color"
android:typeface="normal"
android:gravity="bottom" />
<ImageView
android:id="#+id/app_thumbnail"
android:layout_width="#dimen/product_list_image_dimensions"
android:layout_height="#dimen/product_list_image_dimensions"
android:layout_below="#id/app_name"
android:paddingTop="#dimen/product_list_text_bottom_padding"
android:scaleType="centerCrop"
android:layout_centerHorizontal="true" />
</RelativeLayout>
I have created a layout XML and called setCustomTabView in the right sequence and verified that it's pretty much as described here.
How can custom tab view be implemented using setCustomTabView method in SlidingTabColor sample?
I don't want an image. I only want to control the text size. I want the default on a small phone, but twice the size on a tablet. The default is very small on a tablet. The app is used outdoors and visibility and large buttons is important. I have two "buckets" so far. The following examples are for the default.
If I use this xml layout, I only see the text for the first tab, and no colorizer.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- Default sized TextView for tab title.
This allows us to specify a larger one for tablets in layout-w720dp. -->
<TextView
android:id="#+id/tab_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textStyle="bold"
android:textSize="18dp"/>
</LinearLayout>
If I add the xml for an image and provide a source, it works. If I leave out the source, the result is the same as for a layout with only a TextView.
<TextView
android:id="#+id/tab_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textStyle="bold"
android:textSize="18dp"/>
<ImageView
android:layout_width="wrap_content"
android:src="#drawable/ic_launcher"
android:layout_height="wrap_content" />
In one of my experiments I increased the text size (very large) and without an image I got all four tab titles.
How can I replicate the default tab titles with only a TextView?
(I had a working solution where I detected the metrics at run time and doubled the text size, but I want to control this through different layout subfolders.)
I see that the default tabView is a simple, instantiated TextView and tabTitleView is equated to it. If I could do a findViewByIdon the TextView within my layout I could do the same. But attempts to do that resulted in a null TextView - probably because a ViewGroup is not yet established. But if I use my layout the child already has a parent and can't be used in the tab strip's addView().
This worked.
<TextView
android:id="#+id/tab_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textStyle="bold"
android:textSize="12sp"
android:gravity="center_vertical|center_horizontal"
android:padding="16dp" />
Using the debugger (and looking at the source where the default tabView is created) I saw that gravity was 0x800033 for my TextView and 0x000011 for theirs. Changing the android:gravity and adding the same padding as the default fixed it. I think center would also work. It's an alias for vertical|horizontal (1<<4|1<<0).
I also called setAllCaps(true) on the tabTitleView for consistency.
I have defined text of a textview as -
<string name="text"><u>this is my text</u></string>
I needed some space between the text and the underline, so I added lineSpacingExtra="2dp" to the textview, but it is not working.
Can anyone tell how to achieve this?
I need to support API 14 till 21. The above test was done on API 21.
I spent a great deal of my time on this question and here are my findings!
Firstly, To increase the spacing between the text and underline in css you need to use styles and unfortunately Android TextView does not support style tag when using Html.fromHtml(). Unfortunately even span tag is not supported (otherwise that could have been used). To see the entire list of tags supported check the HTML Tags Supported By TextView blog.
Now since we know the basic simple implementation wouldn't work, the only other way remaining is to fake it (fool the user!). In your xml layout where you have the TextView add a View below it with the following properties.
<TextView
android:id="#+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/text"
android:textSize="20sp"/>
<View
android:id="#+id/underlineView"
android:layout_width="match_parent"
android:layout_height="1dp"
android:layout_alignEnd="#+id/textView"
android:layout_alignLeft="#+id/textView"
android:layout_alignRight="#+id/textView"
android:layout_alignStart="#+id/textView"
android:layout_below="#+id/textView"
android:layout_marginTop="10dp"
android:background="#android:color/holo_red_dark"/>
As you can see the underlineView is emulating the underline. It has its width fixed to the textview above it. You can set its color to whatever you need and importantly you can adjust the spacing using the android:layout_marginTop property. Hope this helps!
My suggestion is to remove the underline from the text string entirely because you can't customize the spacing from there. After that, you have a few options. One option is to use the #drawable feature as discussed in the following link: http://www.quora.com/How-do-I-design-edit-text-view-with-bottom-border-alone-in-Android-and-edit-text-view-with-some-special-symbol-like-below-image
If you want a quick and easy "hack" then go to the layout XML for your activity where your TextView is created. Wrap your TextView in a LinearLayout as follows:
<LinearLayout
android:orientation="vertical"
android:layout_height="wrap_content"
android:layout_width="wrap_content">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/text"
android:layout_marginBottom="2dp" />
<TextView
android:layout_width="fill_parent"
android:layout_height="1dp"
android:background="#color/underline" />
</LinearLayout>
The first TextView is where your text ("this is my text") is displayed so you can adjust the "layout_marginBottom" to whatever spacing you need between your text and the underline. The second TextView acts as your underline so to adjust its thickness you can change the "layout_height" value.
The final step to making this work is to go into your "values" folder in your project and create a new XML file named "colors.xml". The entire contents for this example are below:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="underline">#333333</color>
</resources>
Simply change the hex color value in this XML file to customize the underline color to your choice.
I am working with modified version of sample WeatherListWidget to get a better understanding of App Widgets. Things are fine - except when I try to replace the dark_widget_item and light_widget_item layout files with slightly more complex layout files. Here is original layout:
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/widget_item"
android:layout_width="match_parent"
android:layout_height="46dp"
android:paddingLeft="25dp"
android:gravity="center_vertical"
android:background="#drawable/item_bg_light"
android:textColor="#e5e5e1"
android:textSize="24sp" />
I would like to be able to have multiple text lines. But:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/widget_item"
android:background="#drawable/item_bg"
android:layout_width="match_parent"
android:layout_height="46dp"
android:paddingLeft="25dp">
<TextView android:id="#+id/type_string"
android:textColor="#666666"
android:textSize="20sp" />
<TextView android:id="#+id/title_string"
android:textColor="#666666"
android:textSize="18sp" />
</LinearLayout>
fails.
In fact, it results in "Sorry! The application Launcher (process com.android.launcher) has stopped unexpectedly. Please try again. Force close".
Reinstating TextView widget_item.xml fixes this. I suspect that part of the problem is how I reference RemoteViews in WeatherWidgetService.getViewAt() - but I am getting very little help from DDMS or LogCat or anything else.
Thanks guys, I got the notification. (SO requires a username with length > 2, hence the dot)
Answer as per comment:
I don't see any layout_width and layout_height attributes for both of the TextViews in your LinearLayout - they are mandatory. Also, if you want the two TextViews to be above eachother, add android:orientation="vertical" to the LinearLayout. And just to the record, you can break a CharSequence to multiple lines in a single TextView by adding "\n" inbetween the different elements.
If you're going to include an image as well, then you're probably better off with a LinearLayout than a single TextView indeed, although you could potentially use the intrinsic drawable option of the latter. That could get a little messy though, especially if you're planning on using different styles for the different lines of text... Not impossible, but I'd stick with the LinearLayout. ;)
I'm using a TextView in Android, what I want to show 1 line in TextView ending with ". " but this give [] type box at the end. I don't know why? I just want to remvoe this box and only to show text ending with "... "

Andrew and Stephanie Tidwell candidly share their success story in this business. This story will help everyone listening realize that no one is perfect, even in a second generation business. This is a streaming audio file.
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.
