I have an activity with two Buttons and a TextView in a LinearLayout. My TextView is offset downwards and the text doesn't fit inside the box. Can you explain what is happening? I think it is related to padding, and I've read several discussions about the perils of TextView padding, but that doesn't explain why the text is cut off at the bottom.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:background="#800080">
<Button
android:text="This"
android:background="#drawable/button_red"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
<Button
android:text="That"
android:background="#drawable/button_green"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
<TextView
android:text="Copious amounts of text that overflows onto several lines on a small screen, causing the TextView to dangle below the buttons. Why it does this I can't imagine. I only hope someone can help me with this."
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#533f93"
/>
</LinearLayout>
This code produces this display:
The purple is the LinearLayout, the blue is the TextView. As you can see, the TextView's top is below those of the buttons and its bottom is below the bottom of the LinearLayout. As I add text to the TextView, the LinearLayout increases its height appropriately, but because the TextView is offset, I always lose the bottom of the last line.
I ran Hierarchy Viewer and it gave me this wireframe:
Which shows the vertical offset at the top, but misses the bottom of the TextView. The same wireframe with the LinearLayout selected looks like this:
According to Hierarchy Viewer, the top of the buttons is at 0, but the top of the TextView is at 7. I've tried various fixes, mostly culled from this site:
android:paddingTop="0dp"
android:background="#null"
android:includeFontPadding="false"
None of these fixed my issue.
Set android:baselineAligned property of your LinearLayout to false.
From documentation:
When set to false, prevents the layout from aligning its children's
baselines. This attribute is particularly useful when the children use
different values for gravity. The default value is true.
give the layout_gravity of the Textview to be center_vertical
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

<Button

android:layout_height="wrap_content"

<Button
android:text="That"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

<TextView
android:text="Copious amounts of text that overflows onto several lines on a small screen, causing the TextView to dangle below the buttons. Why it does this I can't imagine. I only hope someone can help me with this."

Try setting the layout_gravity for the TextView like this:
<TextView
android:text="Copious amounts of text that overflows onto several lines on a small screen, causing the TextView to dangle below the buttons. Why it does this I can't imagine. I only hope someone can help me with this."
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#533f93"
android:layout_gravity="top"
/>
If you have this problem with several TextViews you can add android:gravity="center_vertical" to LinearLayout

so I'm currently working on an app on Android, and I got stuck on a specific problem regarding the RelativeLayout, which I can't find a way to solve.
I have in the layout three views as follows: TextView, Textview and ImageView (laid horizontally), here is a screenshot of the ios counterpart:
the Textview at the middle should stick to the first one, until he gets to the Imageview, when he does, he keeps his minimum size (wrap content), while the first Textview truncate.
On IOS I setted priorities to the constraint to accomplish this, but I can't figure out how to solve this on Android.
Here what I tried:
<android.support.percent.PercentRelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:background="#drawable/daily_movie_title_box">
<TextView
android:id="#+id/daily_header_textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="15dp"
android:text="New Text aawi oa ioawfwi"
android:textSize="16sp"
android:textStyle="bold"
android:textColor="#color/white"
android:lines="1"
android:singleLine="true"
android:layout_alignParentStart="true"
/>
<TextView
android:id="#+id/duration_text"
android:text="138 mins"
android:layout_width="100dp"
android:layout_height="wrap_content"
android:textSize="13sp"
android:textColor="#color/white"
android:lines="1"
android:layout_alignBaseline="#id/daily_header_textview"
android:layout_toStartOf="#+id/certification_icon"
android:layout_toEndOf="#id/daily_header_textview"
/>
<ImageView
android:id="#id/certification_icon"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_alignParentEnd="true"
android:src="#drawable/uk12a"
android:layout_alignBottom="#id/daily_header_textview"
app:layout_aspectRatio="100%"/>
</android.support.percent.PercentRelativeLayout>
Which resulted in this (which is what I want):
But when I increase the first Textview text it's not behaving as I desire...
Is it possible to achieve the behaviour I want in Android (keep the middle Textview wrap content, and truncate the first one if needed)?
I will post an update if I find a solution eventually, just wanted to see if anyone can find an easy way to achieve this behaviour, as I suspect there is.
Thanks.
From my understanding, you want the first TextView to be as large as possible, without adding space after the text if the text is too small. The second TextView should only wrap_content, but it should fill the rest of the parent layout when the row doesn't. The ImageView is set to wrap_content.
I tested it with this layout:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<TableLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:shrinkColumns="0"
android:stretchColumns="1">
<TableRow>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:singleLine="true"
android:text="Shrinking text dddddddddddddddddddddd"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Midle column"/>
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#mipmap/ic_launcher"/>
</TableRow>
</TableLayout>
</LinearLayout>
The only problem is that if the second column has a incredibly large text, it will push the other views out of the parent. But in your case, I don't think that will be a problem. Otherwise, I think it does the job.
These are some suggested solutions:
You can use LinearLayout with horizontal orientation and weight for each component (TextViews and ImageView).
You can set the minimum and maximum text length for the second TextView.
But i prefer to apply the first solution. You can assign a weight for each component ( amount of space on the screen ) using:
android:layout_height
I have two RadioButtons within a View that is set within an AlertDialog. Although the text for the first one appears horizontal, the text for the second button comes out vertical. Initially, I thought this was due to the View not filling the width of the dialog itself, but that doesn't appear to be the problem (I've tried making the text smaller and the I get the same result). I'm sure I've come across this in the past, but I can't remember how I resolved it. I'm using RadioButtons elsewhere in my app within AlertDialog's with no issue, so I'm pretty stumped. This is what it looks like. At no point do I hard-code the width of any layout or item in dp; I only ever use match_parent or wrap_content:
So, any help in trying to resolve this would be greatly appreciated!
My layout (LayoutInflator is called on it and then values/listeners are applied):
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/template"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="0dp"
android:orientation="horizontal">
<CheckBox
android:id="#+id/check_box"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.45"
android:textSize="16sp"
android:textColor="#color/Black" />
<RadioGroup
android:id="#+id/radio_group"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.55"
android:orientation="horizontal"
android:enabled="False">
<RadioButton
android:id="#+id/radio_button_1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="16sp"
android:textDirection="ltr"
android:enabled="False"
android:textColor="#color/Black"/>
<RadioButton
android:id="#+id/radio_button_2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="16sp"
android:enabled="False"
android:textColor="#color/Black"
android:checked="true"/>
</RadioGroup>
</LinearLayout>
Inflating the layout like this works fine and gives the desired output:
LinearLayout inflatedLayout = (LinearLayout) this.getLayoutInflater().inflate(R.layout.template, null);
currDialog = CreateDialog.getDialog(this, "Title", inflatedLayout );
currDialog.show();
However, when I add this to a TableRow object, which is then added to a TableLayout object, it gives the unexpected result. I'm going to try with a RelativeLayout first.
You're using layout weights, and you are forcing your RadioGroup take up only 55% of the space. Since the space is not enough, the text goes to vertical. To be 100% sure that your radiogroup will fit, you will need to set it's width to wrap_content.
<RadioGroup
android:id="#+id/radio_group"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:enabled="False">
You might also want to consider changing the orientation to vertical, in which case it will probably fit with only 55% of the space, but I still highly recommend wrap_content
android:id="#+id/radio_button_2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
There isn't enough available space for the second RadioButton to fit it's text, so it stretches the height to be able to fit the text.
I am wondering how to have a TextView display its content on several lines without hardcoding the width in the XML.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="right"
android:orientation="horizontal">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:singleLine="false"
android:text="Long multiline text"/>
<TextView
android:textColor="#color/text_color"
android:layout_width="130dp"
android:layout_height="wrap_content"
/>
</LinearLayout>
Any thought welcome.
EDIT: my problem is that when the text exceeds the width set (because it reaches the end of the screen) a portion of the text is just not displayed. I would expect the text to be split on two lines
Though I cannot reproduce the not wrapping problem, you can fix the positioning problem by using a weight on the first TextView. Using the following XML gives the expected output in the graphical layout view in Eclipse:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="right"
android:orientation="horizontal">
<TextView
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:singleLine="false"
android:text="Long multiline text"/>
<TextView
android:textColor="#color/text_color"
android:layout_width="130dp"
android:layout_height="wrap_content"
/>
</LinearLayout>
Also add
android:minLines="2"
android:scrollHorizontally="false"
You could try
android:inputType="textMultiLine"
in your TextView XML. This worked for me.
I think I had very similar problem. I had a TextView with a text, where I was not sure how much lines will it take. It was encapsulated by a LinearLayout having android:layout_width="match_parent" to ensure my text will fill out all the space horizontally. However, the problem was that my text did not fit into 1 line and when it did break into a new line, the next view component below it did not move downwards to give enough space for the second line to be viewable fully.
I could achieve the solution by changing the LinearLayout that was containing my TextView into a RelativeLayout. By this way, the element below the text (actually below the Layout itself) was moved automatically to give enough space for the multi-line text.
I have a left-aligned TextView and a right-aligned button side-by-side. I want the button to take up as much space as it needs on the right (depending on the text that goes in it) and the left text to fill as much as it can and ellipsize on any overflow.
|Long title that may or may not ellipsi... <Button with text>|
I've read and tried lots of other posts that seem to have similar problems, none of which have worked for me. I've tried both using a LinearLayout with weights as well as a RelativeLayout with layout_toLeftOf assigned, none of which is resulting in what I need.
This is my LinearLayout code (with unnecessary parts taken out) where I give the left TextView a layout_weight of 1 and the button a layout_weight of 0. This should give the right-side button all the space it needs and give the TextView the rest, but instead the left title stops showing up and the right button gets smushed to the side and cut off. I've tried replacing the widths of both the Text and button to 0dip as I've seen suggested, which doesn't change anything.
<LinearLayout
android:layout_height="#dimen/title_bar_height"
android:layout_width="fill_parent"
android:orientation="horizontal">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:ellipsize="end"
android:layout_gravity="left|center_vertical"
android:gravity="left|center_vertical"
android:textSize="22sp"
android:lines="1"/>
<include layout="#layout/action_buttons"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="0"/>
</LinearLayout>
Replacing the layout_weight of the TextView with 0 actually allows the right-side button to properly fit on the screen fully, but the left text still does not show up. If I have both layout_weights set to 0 for the TextView and button and I then change the TextView's width from 0dip to wrap_content, everything shows up but the button instead is squished to fill the remaining space (and the text inside is truncated).
Here is my attempt with a RelativeLayout:
<RelativeLayout
android:layout_height="#dimen/title_bar_height"
android:layout_width="wrap_content">
<include layout="#layout/action_buttons"/>
<TextView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_gravity="center_vertical"
android:layout_alignParentLeft="true"
android:layout_toLeftOf="#layout/action_buttons"
android:gravity="center_vertical"
android:scaleType="center"
android:textSize="22sp"
android:ellipsize="end"
android:lines="1"/>
</RelativeLayout>
Everything aligns fine and shows up, except that the left TextView (when it's too long) overlaps and appears on top of the button rather than truncating and ellipsizing. Shouldn't android:layout_toLeftOf"#layout/action_buttons" specify that the TextView should stay to the left boundary of the button?
I've tried seemingly everything I can find on this site related to this issue, and I still can't get a solution. Any help would be greatly appreciated!
This will do the trick for you:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_gravity="left|center_vertical"
android:layout_weight="1"
android:ellipsize="end"
android:gravity="left|center_vertical"
android:singleLine="true"
android:text="Some really long textttttttttt tooooooooooo make the ellipsize work in the preview"
android:textSize="22sp" />
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button Text" />
</LinearLayout>
Here's what it looks like when run:
And again with a button with more text:
I have a scroll layout with a relative layout in each line. Now is there an image and a text, and I want to limit the height of each line to the text.
So if my image is higher than the text, that the image will be resized to the height of the text (proportional). How can I do this in XML?
At the moment the line definition looks like (copied from the mumble android implementation):
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/RelativeLayout01"
android:layout_height="wrap_content"
android:layout_width="fill_parent">
<ImageView
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:id="#+id/userRowState"
android:src="#drawable/icon" />
<TextView
android:layout_toLeftOf="#+id/userRowStatus"
android:layout_height="wrap_content"
android:text="[Name]"
android:id="#+id/userRowName"
android:ellipsize="end"
android:layout_width="wrap_content"
android:lines="1"
android:singleLine="true"
android:textSize="25sp"
android:layout_centerVertical="true"
android:layout_toRightOf="#+id/userRowState" />
<!--
singleLine is deprecated but it is the only way to get ellipsize work
it seems. 'inputType text, maxLines 1' didn't work. It's a known issue
that Google has been unable to reproduce in 1½ years
http://code.google.com/p/android/issues/detail?id=882 Will see what
happens first, they remove support for singleLine or they manage to
reproduce the error. :p
-->
</RelativeLayout>
Sincerely xZise
You could try aligning the top and bottom of the icon to the top and bottom of the userRowName:
<ImageView
android:id="#+id/userRowState"
android:src="#drawable/icon"
android:layout_width="wrap_content"
android:layout_alignTop="#+id/userRowName"
android:layout_alignBottom="#+id/userRowName"/>
This should make it decrease in size when the text decreases. It will remain centered horizontally on its old position though and it won't grow as it's limited in horizontal direction.
