I'm trying to create a listview item that consists of a textview and a button horizontally.
I want the textview to be on the left and the button to be on the right.
The button always has the same size so I want to let the textview take up the rest of the space.
My problem is that the textview (if it contains a text wider then the screen) pushes the button out of the screen.
I want the textview to not push the button out of the screen - I want the button to always stick to the right side of the screen regardless of how long the text in the textview is.
If the text is too long to be displayed, I just want to display as much as possible (like overflow:hidden in HTML) without pushing the button out to the right.
Is it possible to configure my view to handle this or do I need to do al sorts of measuring of screen width and text length etc. etc.?
Here is my listview item xaml:
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:stretchColumns="0">
<TableRow>
<TextView
android:id="#+id/tv_item_text"
android:text="(123456) Item Name"
android:paddingLeft="10dip"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="fill_vertical"
android:gravity="fill_vertical"
/>
<Button
android:id="#+id/btn_go"
android:layout_width="wrap_content"
android:text="Go"
android:textColor="#android:color/holo_blue_dark"
android:layout_gravity="fill_vertical"
android:gravity="center"
android:visibility="visible" />
</TableRow>
I'm pretty new to Xamarin so if anyone could help me out it would be much appreciated.

I really don't understand why people think using a TableLayout and nest a TableRow inside of it is a good practice for ListView/RecyclerView items...
Why are you not using a RelativeLayout which tells the button to be on the right and make the text view fill the rest of the space?
Should look something like this:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="50dp">
<Button
android:id="#+id/btn_go"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:text="Go"
android:textColor="#android:color/holo_blue_dark"
android:layout_alignParentRight="true" />
<TextView
android:id="#+id/tv_item_left"
android:layout_width="match_match"
android:layout_height="match_parent"
android:layout_toLeftOf="#id/btn_go"
android:layout_alignParentLeft="true" />
</RelativeLayout>

I have a list view with each list item being designed in a RelativeLayout. Within each relative layout I have three buttons and two text views. Everything should be in one row. The first text view is supposed to be left aligned, while the buttons are in one horizontal row aligned to the end of the parent, with the second text view being directly before them. My problem is, that very long text in the primary text view overlaps with the buttons and the second text view. The text does break into a second line if long enough, but I'd like it to break.
For now I have achieved the list to look like this. Sadly the text does not break before the buttons/associated text, but only at the end of the parent.
Previously I had a layout_marginEnd of 160dp, which worked fine on my personal phone, but since then I have received bug reports from users with other phones that own another brand.
My code looks as follows:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:id="#+id/nameTextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_marginStart="10dp"
android:layout_marginTop="12dp"
android:layout_marginBottom="12dp"
android:textIsSelectable="false"
android:textSize="#dimen/listItemTextSize"
tools:ignore="UnusedIds" />
<LinearLayout
android:id="#+id/buttonLayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentEnd="true"
tools:ignore="RelativeOverlap,UnusedIds">
<TextView
android:id="#+id/amountTextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_marginEnd="8dp"
android:textIsSelectable="false"
android:textSize="#dimen/listItemTextSize" />
<ImageButton
android:id="#+id/subtractButton"
style="#style/Theme.ShoppingList.ImageButton"
android:background="#drawable/ic_minus"
android:contentDescription="#string/mainSubtractButtonDescription" />
<ImageButton
android:id="#+id/addButton"
style="#style/Theme.ShoppingList.ImageButton"
android:background="#drawable/ic_plus"
android:contentDescription="#string/mainAddButtonDescription" />
<ImageButton
android:id="#+id/deleteButton"
style="#style/Theme.ShoppingList.ImageButton"
android:background="#drawable/ic_trash"
android:contentDescription="#string/mainDeleteButtonDescription" />
</LinearLayout>
</RelativeLayout>
Thank you in advance for your help!
Add android:layout_alignParentStart="true" and android:layout_toStartOf="#id/buttonLayout" to the nameTextLayout.
This will break nameTextView before LinearLayout and keep nameTextView's text left aligned.
Add android:layout_toStartOf="#id/buttonLayout" to the nameTextLayout. This will make it stop before that linear layout and break there.
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
In my user interface, I have a fragment with a RelativeLayout. At the bottom of this RelativeLayout, I have two buttons: one should be on the left, the other on the right, with empty space between them. The left one has static text (but because the app will be translated, I don't know what width it will be). The text in the right one can change arbitrarily.
Since I already have a RelativeLayout, I started out trying to lay them out inside the RelativeLayout like this:
<Button
android:id="#+id/button_left"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:text="#string/left" />
<Button
android:id="#+id/button_right"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:text="#string/right" />
But this has the problem that if the text in the right-hand button is too long, it will overlap the left-hand button.
I next tried to constrain the left-hand edge of the right-hand button by adding android:layout_toRightOf="#+id/button_left", but with this, the right-hand button would always fill the available width. When the text in the right-hand button is short, I want it to shrink to leave a gap between it and the left-hand button.
I next tried to use a LinearLayout, so I could set layout_gravity on the buttons, like this:
<LinearLayout
android:id="#+id/buttons"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true" >
<Button
android:id="#+id/button_left"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/left" />
<Button
android:id="#+id/button_right"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right"
android:drawableLeft="#drawable/pass"
android:text="#string/right" />
</LinearLayout>
Still no joy. I expected this to work, but the right-hand button stays just to the right of the left-hand button, instead of sticking to the right edge of the screen. I can see in the layout editor that the LinearLayout correctly fills the width of the screen, but the button stubbornly stays next to its friend.
I tried adding android:layout_weight="1" to the right-hand button too, but again, that made it always expand to fill the available space.
Next, I tried to add an empty View between the buttons, to expand and force the right button to the right, like this:
<LinearLayout
android:id="#+id/buttons"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true" >
<Button
android:id="#+id/button_right"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/left" />
<View
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_weight="1" />
<Button
android:id="#+id/button_left"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right"
android:text="#string/right" />
</LinearLayout>
This works fine when the text is short, just like my original RelativeLayout did, but now when the text on the right-hand button is long, its width is limited by the width of the screen, not the available space, so it extends off the right-hand edge of the screen. Again, I can see in the layout editor that the LinearLayout has the correct width, but the button is extending ourside its parent's bounds. This happens even if the button has android:layout_width="match_parent". Oddly enough, increasing the layout_gravity on the right-hand button makes it smaller until it fits inside the available space, but of course that also makes it fill the space when the text is small.
I can't believe it's this hard to get this right. I've seen half a dozen similar questions on SO, but they all have easy workarounds. If the button text is fixed, you can set the margin to a fixed width by hand. If the expanding widget is a TextView instead of a Button, you can just let it expand and use android:gravity to move the text inside the widget, but you can't do that with a button because the background and borders are visible on the screen.
It turns out that adding the LinearLayout was the wrong approach. Using android:layout_toRightOf="#+id/button_left" android:layout_alignParentRight="true" works fine with a TextView, because that can soak up the available space without changing its appearance. Instead of trying to change the layout, I just need to use something that can expand to fill the available space and contain the Button: a FrameLayout. Here's the working code, which still goes inside my root RelativeLayout:
<Button
android:id="#+id/button_left"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:text="#string/left" />
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:layout_toRightOf="#+id/button_left" >
<Button
android:id="#+id/Turn_button_pass"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right"
android:text="#string/right" />
</FrameLayout>
Now, the FrameLayout always takes up all the space to the right of the left-hand button, and lays out the right-hand button inside that space using android:layout_gravity="right".
This answer only adds one extra layout, but if someone has a way to do it only using the existing RelativeLayout, to minimise the number of ViewGroups in the layout, I'll accept that as a solution.
IF you can live with the constraint, that the right button only can take up to up half of the available space, this could be a solution for you:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true" >
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_weight="1" >
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="A short text" />
</RelativeLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1" >
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="A very long text which is limited to one half of the available space" />
</RelativeLayout>
</LinearLayout>
You could just use a TextView and make it look like a button. Create a dummy button, extract the background and set that background to the textfield programmatically.
(Not tested but should give it the apperance of a button)
Drawable d = button1.getBackground();
textView1.setBackground(d);
then you just set the onClickListener and that should yield what you're looking for. The TextView would take the place of the "button_right" in your first layout.
**Edit
Your xml would look something like this
<Button
android:id="#+id/button_left"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:text="#string/left" />
<TextView
android:id="#+id/button_right"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:maxEms="10"
android:text="TextView" />
I wanted to make two equally-sized radio buttons with a custom background, text, and an image to the right of the text. Because of how different these are from a standard "Button", I made them using a clickable "RelativeLayout".
The text and the image are of different heights, but I want each one to be centered vertically in the button. I also want the combination of the text+image to be centered horizontally in the button. This second part is what I'm having trouble with; it's off-center, close to the left side. In the image below, the left side is what I want, but the right side is what's happening. The image on one of the buttons (the one with the longer text) is resized to be smaller, too... Though there is still plenty of space on the right side of the button.
Here is my code:
<LinearLayout
android:baselineAligned="false"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<RelativeLayout
android:id="#+id/my_button"
android:background="#drawable/radio_button"
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:gravity="center_horizontal">
<TextView
android:id="#+id/button_textview"
android:text="#string/button_label"
android:textAppearance="?android:attr/textAppearanceButton"
android:layout_centerVertical="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"></TextView>
<ImageView
android:contentDescription="#string/image_description"
android:id="#+id/button_imageview"
android:layout_centerVertical="true"
android:src="#drawable/my_icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/button_textview">
</ImageView>
</RelativeLayout>
<RelativeLayout
... same thing for the second button ...
</RelativeLayout>
</LinearLayout>
What am I doing wrong?
Use this as your button:
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_gravity="center_horizontal"
>
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:text="MyButton"/>
<ImageView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:src="#drawable/my_image"/>
</LinearLayout>
Now, you can place it in other parent views. To apply layout attributes to above button, place those attributes in the outer <LinearLayout> tag of above button.
Alternative:
You can set custom images to be drawn on sides(Left,Right,Top,Bottom) of a TextView using attributes like:
android:drawableLeft="#drawable/my_image"
Turns out the solution was adding
android:paddingRight="0dip"
strangely enough, even though I didn't put any padding there in the first place.
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:
