Vertical text spacing changed in Android 4.0 - android

I have an app that allows the user to change the text size. On Android 2.X when you made the text smaller the vertical spacing got smaller too. On 4.X the text gets smaller and the spacing remains the same.
The call that I am using to change the size is (there is a loop to change multiple lines):
tvData[i].setTextSize(TypedValue.COMPLEX_UNIT_PX, fSize);
The text fields are described in main.xml as follows (there is more than one and they are each "below" the previous one.
<TextView android:id="#+id/textOut1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:typeface="monospace"
android:textSize="28dip"
android:textColor="#000000"
android:textStyle="bold"
android:layout_below="#id/textOut0"
/>
What do I have to do so this works in both old and new Android?

The fix was to not put each line of text in a separate TextView. By putting all of the text in one TextView and ending each line in a newline it now adjusts vertical spacing when the font size is changed.
And the change to one has been tested to work on older versions of Android too.
I cannot remember why I used an array of TextViews in the first place, seems like a bad choice looking at it now, but it did work with older versions.

Android Text in different language take different height

We are showing some text in our application (say in a RecyclerView with GridLayoutManager). This text is shown in different languages as highlighted in the image below. Due to this, the height of TextView is different as different language fonts are taking different spacing.
Please refer to the sample image below and the required code to draw the text view.
<com.google.android.material.textview.MaterialTextView
android:id="#+id/tv_title_one"
android:layout_width="0dp"
app:layout_constraintWidth_percent="0.5"
android:layout_height="wrap_content"
android:layout_marginStart="8dp"
android:layout_marginTop="10dp"
android:fontFamily="#font/lato_bold"
android:gravity="start"
android:maxLines="3"
android:minLines="1"
android:singleLine="false"
android:includeFontPadding="false"
android:textColor="#541388"
android:letterSpacing="0"
android:lineSpacingExtra="0dp"
android:textSize="32sp"
android:textStyle="normal"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
tools:text="Class 12th (Biology) 2021 - 2022" />
Dummy layout with two similar text views but with different language
Please let me know if there is anything missing in the problem description. Thanks for your valuable feedback.
Update #1:
Since there is no direct answer to it. We are going with making card height and text height-restricted as mentioned in the accepted answer.
I just think that the reason could come from the font you are trying to use for rending text in this TV. For every language, the character size maybe vary a bit from width to height due to the language specs.
Could you try to use the default system font to check if you still have that spacing issue?
Or another suggestion would be:
Use autoSizeMaxTextSize, autoSizeMinTextSize feature to allow text size being automatically resize to fix the textview when possible.
Apply a fix Height for your text content with extra Vertical Space, and add android:ellipsize as your wish.
Still wonder:
Is your app displaying multiple language at a same time on UI?

Auto-sizing TextView does not size to fit updated text

I'm using an Android auto-sizing TextView via the appcompat library, as below:
<android.support.v7.widget.AppCompatTextView
android:id="#+id/info"
android:layout_width="100dp"
android:layout_height="wrap_content"
android:maxLines="1"
app:autoSizeTextType="uniform"
app:autoSizeMinTextSize="8sp"
app:autoSizeMaxTextSize="14sp"
app:autoSizeStepGranularity="0.5sp"
android:text="#string/something" />
This works nicely the first time the text is set - eg the text size shrinks if it needs to.
But the second time it's set, the text size doesn't grow again if the content is small enough to allow it. It remains at the smaller size appropriate for the previous content.
So, what is the proper procedure for calling setText on an auto-sizing TextView, so that the auto-sizing parameters are respected? Or is there a way to force the TextView to re-evaluate its content and resize the text?
I have tried setting the text size back to the default before calling setText but that seems to have no effect.
By reproducing your code I faced the same problem and the only solution that worked is giving a specific height to the TextView like: android:layout_height="30dp" From: https://developer.android.com/guide/topics/ui/look-and-feel/autosizing-textview#setting-textview-autosize
If you set autosizing in an XML file, it is not recommended to use the
value "wrap_content" for the layout_width or layout_height attributes
of a TextView. It may produce unexpected results.

TextView text multiple lines for Android v4.1+

I have a TextView in Android with a Text that can vary quite a bit in length. It could be a single word, it could also be more than ten full sentences.
My TextView has android:layout_width="match_parent" and android:layout_height="wrap_content". I've looked around and found a lot of ways to make it wrap over multiple lines (some requiring multiple of these):
android:scrollHorizontally="false"
android:singleLine="false"
android:ellipsize="none"
android:maxLines="10"
etc.
So my question is: Which should I use to wrap my TextView-Text in Android version 4.1+?
PS: I haven't tested any of these yet, but since I've found so many different answers on SO-questions about Text-Wrapping, I was wondering what the "best" method is (for my Android version).
I ended up using:
<TextView
...
android:layout_width="match_parent"
android:layout_height="wrap_content"
...
android:scrollHorizontally="false"
android:ellipsize="end"
android:maxLines="10" />
When I looked at the singleLine in Eclipse it gave the following java-doc:
Constrains the text to a single horizontally scrolling line instead of
letting it wrap onto multiple lines, and advances focus instead of
inserting a newline when you press the enter key. * Deprecated: This
attribute is deprecated. Use "maxLines" instead to change the layout
of a static text, and use the "textMultiLine" flag in the inputType
attribute instead for editable text views (if both singleLine and
inputType are supplied, the inputType flags will override the value
of singleLine). [boolean]
So I now use maxLines="10", since I don't want an entire life-story to be inside the TextView, 10 lines should be a good maximum. I've added the ellipsize="end" to have three dots (...) at the end of the text when it has more than 10 lines. And the scrollHorizontally="false" does the trick of allowing multiple lines without a horizontal scroll-bar.
try setting this attributes:
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:ellipsize="none"
android:singleLine="false"
here
to elipsize, a neologism, means to shorten text using an ellipsis, i.e. three dots ... or more commonly ligature …, to stand in for the omitted bits.
Say original value pf text view is aaabbbccc and its fitting inside the view
start's output will be : ...bccc
end's output will be : aaab...
middle's output will be : aa...cc
marquee's out put will be : aaabbbccc auto sliding from right to left

textview doesn't go multiline

Here's my XML layout example of one of my TextViews which show itself correctly in android 4.2 ... I've downgraded a Nexus S to gingerbread 2.3.6 to test out my application and debug it! Right now, each of my TextViews doesn't take any more space than one line, not even wrapping itself at the end of the first line. (On 4.2, the example below was taking 3 lines and was adding "..." at the end if there was some text missing!)
How can I make my textViews compatible with gingerbread? Thank you!
<TextView
android:id="#+id/TV_guideRow_subtitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="#+id/TV_guideRow_title"
android:layout_below="#+id/TV_guideRow_title"
android:text="blabla text that could go up to 3 lines"
android:textColor="#3BB9FF"
android:layout_alignParentRight="true"
android:layout_above="#+id/TV_guideRow_more"
android:layout_marginRight="8dp"
android:layout_marginBottom="3dp"
android:ellipsize="end"
android:maxLines="3"/>
You want:
android:inputType="text|textMultiLine"
Also, depending on the parent of that TextView, multiline may not render properly. Try manually setting the height to, say, 100dp and see if that works.
After some more investigation, I've found out that all my related textView problems were related to my custom theme, which was made for android 4.0+ (since Holo was used as the base theme)
I've set the APIs which doesn't have holo to use the "Light" theme and everything is showing up correctly without any further modification.

How to wrap text in textview in Android

Does any one know how to wrap text in TextView in Android platform. i.e if the text in textview exceed the screen length it should be displayed in the second line.
I have searched and tried the following:
android:scrollHorizontally="false",
android:inputType="textMultiLine",
android:singleLine="false"
But none work..
Can anyone suggest how can I do it.
Constraint Layout
<TextView
android:id="#+id/some_textview"
android:layout_width="0dp"
android:layout_height="wrap_content"
app:layout_constraintLeft_toLeftOf="#id/textview_above"
app:layout_constraintRight_toLeftOf="#id/button_to_right"/>
Ensure your layout width is zero
left / right constraints are defined
layout height of wrap_content allows expansion up/down.
Set android:maxLines="2" to prevent vertical expansion (2 is just an e.g.)
Ellipses are prob. a good idea with max lines android:ellipsize="end"
0dp width allows left/right constraints to determine how wide your widget is.
Setting left/right constraints sets the actual width of your widget, within which your text will wrap.
Constraint Layout docs
For me this issue only occurred on Android < 4.0
The combination of parameters I used were:
android:layout_weight="1"
android:ellipsize="none"
android:maxLines="100"
android:scrollHorizontally="false"
The maxLines count seemed to be the random final piece that made my TextView wrap.
For the case where the TextView is inside a TableLayout, the solution is to set android:shrinkColumns="1" on the TableLayout. (Replace 1 with the column number the TextView you want to wrap is in. (0-indexed))
AFAICT, no other attributes are needed on the TextView.
For other cases, see the other answers here.
FWIW, I had initially gotten it to sort of work with
<TextView
android:id="#+id/inventory_text"
android:layout_width="fill_parent"
android:layout_weight="1"
android:width="0dp"
but that resulted in some extra empty space at the bottom of the Dialog it was all in.
Use app:breakStrategy="simple" in AppCompatTextView, it will control over paragraph layout.
It has three constant values
balanced
high_quality
simple
Designing in your TextView xml
<android.support.v7.widget.AppCompatTextView
android:id="#+id/textquestion"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:scrollHorizontally="false"
android:text="Your Question Display Hear....Your Question Display Hear....Your Question Display Hear....Your Question Display Hear...."
android:textColor="#android:color/black"
android:textSize="20sp"
android:textStyle="bold"
app:breakStrategy="simple" />
If your current minimum api level is 23 or more then in Coding
yourtextview.setBreakStrategy(Layout.BREAK_STRATEGY_SIMPLE);
For more refrence refer this BreakStrategy
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
This should fix your problem: android:layout_weight="1".
By setting android:maxEms to a given value together with android:layout_weight="1" will cause the TextView to wrap once it reaches the given length of the ems.
OK guys the truth is somewhere in the middle cause you have to see the issue from the parent's view and child's. The solution below works ONLY when spinner mode = dialog regardless of Android version (no problem there.. tested it in VD and DesireS with Android =>2.2) :
.Set you spinner's(the parent) mode like :
android:spinnerMode="dialog"
Set the textview's(child custom view) properties to :
android:layout_weight="1"
android:ellipsize="none"
android:maxLines="100"
android:scrollHorizontally="false"
I hope this works for you also.
In Android Studio 2.2.3 under the inputType property there is a property called textMultiLine. Selecting this option sorted out a similar problem for me. I hope that helps.
Just was working on a TextView inside a layout inside a RecyclerView. I had text getting cut off, ex, for Read this message, I saw: Read this. I tried setting android:maxLines="2" on the TextView, but nothing changed. However, android:lines="2" resulted in Read this on first line and message on the 2nd.
Try #Guykun's approach
android:layout_weight="1"
android:ellipsize="none"
android:maxLines="100"
android:scrollHorizontally="false"
Also, make sure that parents width is not set to wrap content. This is the thing that I was missing.
I had the same problem. Following change made it work -
android:layout_width="wrap_content"
The ellipsis, maxLines, or layout_weight - all didn't make any difference.
Note - The parent width is also set as wrap_content.
All you have to do is to set your textview width.
android:layout_width="60dp"
you can change the width to your choice. Just type long sentence to check if it working like this
android:text="i want to be among world class software engineer"
I am using Android 2.2 and my textview will automatically goto the next line if it exceeds the screen.
If you would like to have the text goto the next line before the end of the screen, just add in (just put in your own dp value). This will be useful if you have a picture on the right of the text.
android:layout_marginRight="52dp"
Strange enough - I created my TextView in Code and it wrapped - despite me not setting anything except standard stuff - but see for yourself:
LinearLayout.LayoutParams childParams = new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT);
childParams.setMargins(5, 5, 5, 5);
Label label = new Label(this);
label.setText("This is a testing label This is a testing label This is a testing label This is a testing labelThis is a testing label This is a testing label");
label.setLayoutParams(childParams);
As you can see from the params definition I am using a LinearLayout. The class Label simply extends TextView - not doing anything there except setting the font size and the font color.
When running it in the emulator (API Level 9) it automatically wraps the text across 3 lines.
Just set layout_with to a definate size, when the text fills the maximum width it will overflow to the next line causing a wrap effect.
<TextView
android:id="#+id/segmentText"
android:layout_marginTop="10dp"
android:layout_below="#+id/segmentHeader"
android:text="You have the option to record in one go or segments(if you swap options
you will loose your current recordings)"
android:layout_width="300dp"
android:layout_height="wrap_content"/>
The trick is with the textView width, try to make it dedicated number like:
<TextView
android:layout_width="300dp"
android:layout_height="wrap_content"/>
I've tried many solutions without any result, I've tried:
android:ellipsize="none"
android:scrollHorizontally="false"
the only one thing triggred the wrap option is the dedicated width
You need to add your TextView in a ScrollView with something like this :
<ScrollView android:id="#+id/SCROLL_VIEW"
android:layout_height="150px"
android:layout_width="fill_parent">
<TextView
android:id="#+id/TEXT_VIEW"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="This text view should act as header This text view should act as header This text view should act as header This text view should act as header This text view should act as header This text view should act as header This text view should act as header" />
</ScrollView>
