I have a TextView with a height depending on previous content, but there might be a long Text in it. How can I cut it off at the right point and concatenate three dots or something similar to the new end?
Currently it looks like this:
I found some solutions for Single Line Text, but how does it work with more than one line? I also do not know the number of lines, because this depends on the screen size.
Are there other typical ways on Android to show that the text can be extended? E.g. a colour gradient in the last line?
Edit:
When I do it without a fixed heigth, I have to make the height depend on the element above and my XML will look like this:
<TextView
android:id="#+id/podcastShortDesc"
android:text="Long text"
android:layout_below="#+id/podcastTitle"
android:layout_toRightOf="#+id/podcastLogo"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:maxLines="3"
android:ellipsize="end"
android:layout_above="#+id/podcastMoreAction" />
When I do specify maxLines I can have luck an it will work:
But if the title is too big, it does not work:
You should add following code for "3 dots" at the end.
android:ellipsize="end"
You should remove fixed height property
android:layout_height="50dip"
instead you should add number of lines
android:maxLines="4"
android:layout_height="wrap_content"
Android will take care everything else. In this way, even if text is smaller than 4 lines, android will take care size. If it is more than 4 lines, it will add "3 dots" :) Specify fixed height may cut your text.
Try this. Hope it will work.
<TextView
android:id="#+id/podcastShortDesc"
android:text="LONG LONG LONG TEXT"
android:layout_width="match_parent"
android:layout_height="50dip"
android:maxHeight="50dp"
android:ellipsize="end"/>
I have tested 50dp can show two line in normal font size. So in 50dp height you should add maxLines 2.
Try this fix layout_height and add scroll in your textview
<TextView
android:id="#+id/text1"
android:layout_width="match_parent"
android:layout_height="50dip"
android:text="Hello......"
android:scrollbars="vertical"/>
I am trying to do the right to left text direction, but I am getting unexpected result (not like the one when I do html css). Here is the code I have for that textview:
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="96dp"
android:gravity="right"
android:text="#string/welcomeMsg"
android:textAlignment="center"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="#color/white"
android:textDirection="rtl"
android:textSize="#dimen/welcomeMsgSize" />
I believe I did everything there is to do. Maybe I forgot something or don't know it. I am pretty new to android. The picture shows the output of the above The problem here is the whitespace preceding the text inside the textview and post the text too. Thanks for your help in advance :)
You should change Textview gravity from "Center" to "Right" or "Left" Depending on your need.
Gravity will set gravity to your text so change it. And also change the text alignment from center to right or left.
android:textSize="#dimen/welcomeMsgSize" there lies the culprit.. reduce the size you specified in that file there..!!
I've been spending some hours trying to figure this problem out, and maybe I'm missing something obvious...
I'm trying to get three TextViews placed side by side working. I want all of them to be equally large, no matter what text they contain, and if the text won't fit in one of them, the text should be replaced by "..." at the end in that particular textview (with help of ellipsize).
| <>TextView>> <>TextView>> <>TextView> |
As I said, I need them to be equally large at all times. This can "easily" be done by a LinearLayout using weights, however then ellipsize won't work (or at least I won't get it working), since it seems you need an absolute width size to get it to work.
I've been trying with LinearLayouts, RelativeLayouts, TableLayouts, and finally I went with a combination of an xml layout and a programatically approach (this seems far more advanced than it needs to be, but that was the only way I was able to become close). However, now I use an absolute width (setting it programatically), but although I'm multiplying it with a proper densitymultiplier, it will look different on different screens. On a 4.3" screen there will be some space over which I could have used, on the other hand on a 2.7" screen it looks pretty good.
So any ideas how I can achieve this with a layout? I've been looking around a bit on forums as well, the problem is that most people only want one textview to have the ellipsize function, and not all of them...
Below you'll find my first attempt to get it working, but since I think an absolute width is needed in order for ellipsize to work, it won't work. Setting the width to "1dp" for example won't really do the trick either.
Any suggestions would be highly appreciated!
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:layout_marginTop="10dip"
>
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:editable="true"
android:ellipsize="end"
android:singleLine="true"
>
</TextView>
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:editable="true"
android:singleLine="true"
android:ellipsize="end"
>
</TextView>
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="right"
android:editable="true"
android:ellipsize="end"
android:singleLine="true"
>
</TextView>
</LinearLayout>
It worked for me when I removed the android:editable="true" part.
If you want that to be a user-editable field use EditText instead. That one (afaik) does not support ellipsize though.
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>
I'm trying to create standard button in android with a background and some text in front but some fairly specific alignment. I want the text to be centered vertically and on the left with 20dp of padding. The alignment works but the padding doesn't. I know I could probably get the desired effect by putting a few spaces in the text but that seems like a hack and next I want to do a similar thing but with the text at the top so I would prefer a more elegant solution.
Here's what I have:
<Button
android:layout_width="312dp"
android:layout_height="95dp"
android:id="#+id/gv_music_button"
android:text="Music"
android:textSize="30sp"
android:paddingLeft="20dp"
android:gravity="left|center_vertical"
/>
My mistake, padding was working correctly. Just didn't appear to be.
