I have a layout/alignment problem with a TextView which I haven't yet been able to find a solution for, that is, I want to align text off-center inside a TextView horizontally.
To give a little more context, I have an ImageView and a TextView side by side, the ImageView touching the left edge of the screen and the TextView filling the rest of the screen horizontally, like this:
[-img-|-----text-----]
The TextView is configured as singleLine="true" and maxLines="1", so that it will be truncated if its too long for its horizontal space. My aim is to align the text in the center of the screen, not the center of the TextView, because there are other elements on the screen that are aligned to the center and I need the text aligment to match that.
So, if I use gravity="center" on the TextView, I get the image above, but what I actually want is
[-img-|--text--------]
I tried putting image and text in a RelativeLayout, so that the TextView actually touches both edges of the screen, which does what I want with respect to the alignment, except that if the text is long enough, the first characters will be hidden by the image, since the TextView lies behind the image view.
I also experimented with margins, padding and a compound drawable to the left, but the text is always centered relative to the available space (which I would consider the expected behavior).
Does anybody have any clues on how to achieve this alignment, i.e. relative to the center of a different component than the TextView, maybe programmatically at runtime? Thanks in advance for any helpful advice.
Edit: user Budius suggested using padding to the right to achieve a centered alignment which works but leads to long texts being truncated before the right edge of the TextView is reached and I'm looking for a solution that avoids that, i.e. that uses the entire avilable space, if possible.
I believe that will center it and the move 20dp to the side.
gravity:centre padding:right=20dp
Try using
android:layout_weight="1"
if it helps you..
I know this is not the correct approach than too give it a try..
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight=".33"
android:src="#drawable/ic_launcher" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_weight=".33"
android:gravity="center"
android:text="text" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight=".33"
android:src="#drawable/ic_launcher"
android:visibility="invisible" />
I'm trying to achieve the following layout: a fixed width TextView aligned to the left of its parent, with the text inside it aligned to the right side of that TextView (that's why fixed width, can it be done other way?) and the rest of the parent is filled with a drawable (simple line). Like this:
It's a ListView containing 2 types of rows and the layout for the rows with lines is quite trivial - LinearLayout with TextView and ImageView (I can post the exact code later if needed). And I'm getting a warning that it could be replaced with a single TextView with compound drawable.
I'm all for optimization so I really tried to follow that advice. Unfortunately I wasn't able to get the same result - the line is either constrained to TextView's width or text is aligned to the right side of the ListItem, now to fixed position.
Am I missing something?
Edit: Apparently it is not actually possible and since there are some other complications (the drawable is now a level-list drawable, which is not always a line and sometimes it has a non-fixed height that I have to set) I will leave it as it is now - linear layout, containing one TextView and one ImageView.
I don't think that you're missing anything. The TextView compound drawable features are not very customizable and in general are not worth the time you spend trying to get them to look right. Some lint warnings are a little overzealous and premature.
The optimization that the lint refers to is something that is better attributed for a fixed size image. In your case, the line has to stretch the rest of the screen length and as such it is not something that can be done with a textview with compound drawable. This kind of lint warning is more of a suggestion rather than something that MUST be done and is detected by just checking for a linear layout with only a textview and an imageview rather than checking what would need to go in the image view. If you already have it working the way you did it I think you should leave it alone.
Your view create from this -
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<TextView
android:id="#+id/time"
android:layout_width="#dimen/today_time_width"
android:layout_height="wrap_content"
android:layout_gravity="left"
android:gravity="right"
android:layout_marginRight="5dp" />
<ImageView
android:layout_gravity="center"
android:id="#+id/border"
android:layout_width="match_parent"
android:layout_height="#dimen/today_current"
android:src="?attr/item_boundary" />
</LinearLayout>
There is no way to achive this using only standart TextView. If you really want to reduce view count you can create your custom TextView class, set layoutWidth to matchParent and draw line from text end to right border. But it's not worth to be doing. Some extra views won't slow your list.
I am not sure if you will be able to achieve what you really want to , but then you could change the linear layout in the link you posted to something like this:
<RelativeLayout
android:id="#+id/relTrial"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/txtTime"
android:layout_width="100dp"
android:layout_height="wrap_content"
android:gravity="right"
android:text="12:45 AM"
android:layout_alignParentLeft="true"/>
<LinearLayout
android:id="#+id/lnrSep"
android:layout_width="fill_parent"
android:layout_height="1dp"
android:gravity="bottom"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
android:layout_centerVertical="true"
android:orientation="horizontal"
android:background="#android:color/darker_gray"
android:layout_toRightOf="#+id/txtTime"
android:layout_alignParentRight="true"></LinearLayout>
</RelativeLayout>
This way the time text will be right aligned although being at the left side, and the line will also be visible.
Hope that helps.
If I got you right, you want to add bottom border to list view item?
What about to try this:
android:drawableBottom="#drawable/line"
I am trying to port my WP7 app to android.
Does anyone know how I can layout the text on a single button so that some text appears aligned left and other text appears aligned right? (See below). I need access to be able to dynamically change the percentage number on the right side using code but the text on the right is just static.
Anyone know the answer to this?

Yes you could make it two buttons.
Remove all padding and margin from between them.
Set the same background drawable.
And just ensure when the left is clicked it invokes the right's onPress method (so it looks as if they depress together).
Or wrap the buttons/imageviews/textviews in a layout and perform the onClick on that.
I would use a RelativeLayout for this.
<RelativeLayout
android:width="fill_parent"
android:height="wrap_content"
android:clickable="true"
android:background="#18a2e7"
android:padding="10dip">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Something" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_align_parentRight="true"
android:text="0%" />
</RelativeLayout>
Hey, I've been trying to fix this problem for a long time, The problem
is that some characters in the text are out of the screen, here is a
screenshot of what I mean:
xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:background="#drawable/list"
android:orientation="vertical"
android:padding="15dip"
android:layout_width="fill_parent"
android:id="#+id/relativeLayout1"
android:layout_height="fill_parent">
<TextView
android:textSize="20sp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#000"
android:id="#+id/Munawwat_Text_TextView_text"
android:layout_alignParentRight="true"
/>
</RelativeLayout>
Can anyone suggest a way/workaround to fix this problem?
A workaround for this is to put it into an EditText. If I put the text
into the EditText, the EditText gets horizontally scrollable
(scrollable for ~3px) which is good so you can see the characters that
are out of the screen but i dont want to let the users mess with the
text.. So:
Is it possible to not allow the users to edit in the EditText and
in the same time let the EditText get scrollable?
Is there any other view that i can put the TextView into it, so it
can get scrollable a bit so I can see the characters? (limit the
scroll of the view)
Is there a way to limit the number of characters in each line in
the TextView?
I know I asked a lot though this is one of the last problem I have so
I would really appreciate any comment/suggestion!
Thanks.
You could wrap your TextView in a ScrollView. Or make the text smaller. Or try adding padding on the left to see if it forces linebreaks.
and try to use weight :D
it limites number of caracteres in textview
android:maxLength
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>
