How to create an EditText of dynamic fixed width - android

I'm working on an app where my xml looks a bit like this:
<TableRow
android:layout_width="match_parent"
android:layout_height="fill_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/receiver_name"
android:layout_weight="1" />
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="3"
android:maxLength="30"
android:maxLines="1" />
</TableRow>
What I want, is that no matter what device you have, the TextView should take up 1/4th of the width, and the EditText should take up 3/4ths of the width.
As it is now, the code works - until you start typing. The EditText gets wider and wider as you type more and more into it. How do I make it so that my EditText stays the same width that is assigned to it by the layout_weight parameters?

you should use LinearLayout like that :
<LinearLayout
android:layout_width="match_parent"
android:layout_height="fill_parent">
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="#string/receiver_name"
android:layout_weight="1" />
<EditText
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="3"
android:maxLength="30"
android:maxLines="1" />
</LinearLayout>
hope that can help you =)

Just like Janoub said you could use the LinearLayout and weights value.
http://developer.android.com/guide/topics/ui/layout/linear.html
But you can also use table layout with 4 columns so your edittext catches 3 columns and the textview 1.

Move View to "next line" if it doesn't fit

So, idea in this: I have two TextViews, first can expand whatever it wants, second always 5 chars (time). Problem is in that first TextView can easily push second out of the screen.
So, what I need is something like adjustable LinearLayout, or maybe some GridLayout that will move second TextView on some sort of second line if it doesn't fit parent.
For example you can watch at message bubbles in Viber and WhatsApp. Thanks for any advise.
Update 1
Here is XML that i have now (Only message part)
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/messageBox"
android:layout_gravity="center_vertical"
android:gravity="center_vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="14sp"
android:layout_gravity="center_vertical"
android:gravity="center_vertical"
android:textAppearance="#style/Base.TextAppearance.AppCompat.Medium"
android:textColor="#color/black"
android:text='#{mess.message}'/>
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center_vertical|end"
android:gravity="center_vertical|end"
android:paddingLeft="8dp"
android:textSize="12sp"
android:textAppearance="#style/Base.TextAppearance.AppCompat.Small"
android:text='#{Utils.parseMillsToHoursAndMins(mess.date)}'/>
</LinearLayout>
Update 2
So I added layout_weight to first TextView, that helped with my first problem, but now I have new one. This two TextViews are in LinearLayout which is in another LinearLayout with another TextView. Parent LinearLayout have width set to wrap_content so if top TextView will be bigger than 2 TextViews it will cause child LinearLayout to be less than it's parent, and 2nd TextView (from that 2) wouldn't be in the end of parent. But when child LinearLayout is bigger, all appears to be OK. I know it's complicated, so this is XML
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:minWidth="0dp"
android:id="#+id/contentPanel"
app:bringToFront="#{true}"
android:orientation="vertical"
android:background="#{(mess.isMine?#drawable/chat_bubble_right:#drawable/chat_bubble_left)}">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text='#{!mess.authorRole.equals("Client")?(mess.authorRole + " - " + mess.author):mess.author}'
android:textColor='#{mess.authorRole.equals("Lawyer")?#color/colorPrimary:mess.authorRole.equals("Admin")?#color/red:#color/green}'
android:textSize="12sp"
android:id="#+id/author"
android:fontFamily="sans-serif-medium"
android:textAppearance="#style/Base.TextAppearance.AppCompat.Small"/>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/messageBox">
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:textSize="14sp"
android:layout_gravity="center_vertical"
android:gravity="center_vertical"
android:layout_weight="0.7"
android:textAppearance="#style/Base.TextAppearance.AppCompat.Medium"
android:textColor="#color/black"
android:text='#{mess.message}'/>
<TextView
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:paddingLeft="8dp"
android:textSize="12sp"
android:gravity="bottom|end"
android:textAppearance="#style/Base.TextAppearance.AppCompat.Small"
app:checkFit="#{false}"
android:text='#{Utils.parseMillsToHoursAndMins(mess.date)}'/>
</LinearLayout>
</LinearLayout>
The new approach for achieving such behaviour is using ConstraintLayout with Flow. Here is an example of usage:
<androidx.constraintlayout.helper.widget.Flow
android:id="#+id/socialsButtonsFlow"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginTop="6dp"
app:flow_horizontalGap="8dp"
app:flow_verticalGap="4dp"
app:flow_wrapMode="aligned"
app:flow_horizontalStyle="spread_inside"
app:constraint_referenced_ids="vkButton,twitterButton,facebookButton,youtubeButton,instagramButton,odnoklassnikiButton,tiktokButton"
app:layout_constraintEnd_toEndOf="#id/socialsLabel"
app:layout_constraintStart_toStartOf="#+id/socialsLabel"
app:layout_constraintTop_toBottomOf="#+id/socialsLabel" />
For small screens it looks like this:
I am not sure this will help you or not but:
Use: https://github.com/ApmeM/android-flowlayout
<org.apmem.tools.layouts.FlowLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
</org.apmem.tools.layouts.FlowLayout>
Inside FlowLayout you can put your view's and it will auto move to next line if not fit.
if your textviews in linearlayout you can add weightSum method

My Edittext getting extended while typing the text

My Edittext its getting extend automatically while typing the text,Dont know what mistake i have done, please check my screen shot for exactly what my issue is, help me to find a solution. Thanks in advance.
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="50dip"
android:gravity="center"
android:orientation="vertical" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center" >
<EditText
android:id="#+id/oldpass"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/selectdate"
android:ems="10"
android:hint="#string/oldpass"
android:inputType="textPassword"
android:paddingLeft="5dip" >
</EditText>
</LinearLayout>
</LinearLayout>
check my screen shot for how its extend while typing
your height and weight are Wrap_content as it adjust upon the length of the text you given
change that to fixed dp length
android:layout_width="150dp"
android:layout_height="wrap_content"
It is due to this layout definition: android:layout_width="wrap_content"
You're basically telling that your EditText should fit the content. That means it will have a default size, but once you're typing in it and making it wider, it will extend according to the text it has inside.
You probably want to use android:layout_width="match_parent" to fit it to the screen, or play around with android:layout_weight to make it proportional to other layout items.
Set WEIGHT property of your edittext it will not extended.
android:layout_width="0dp"
android:layout_weight="1"
Try this
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:gravity="center" >
<EditText
android:id="#+id/oldpass"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/selectdate"
android:ems="10"
android:hint="#string/oldpass"
android:inputType="textPassword"
android:paddingLeft="5dip" >
</EditText>
</LinearLayout>
I believe your issue is you are setting the layout_width of the EditText as wrap_content

android make left textview to be shorten and right remain fully visible

I need to display two single-line TextViews horizontally. The left TextView (let's name it 1) may have a longer text which may shortened and finished with "...". The right text view (2) has a short text and should never get shortened.
I want the 1 to remain aligned to the left end of the parent. The 2 aligned to the right side of 1.
There are now 2 conditions that I have to meet
a) if the 1 has a short text then the 2 should get aligned to the right of 1 (none of the gets shortened).
b) but if the 1 has a too long text then the text of 1 should be shortened by '...' while the view 2 is moved maximally to the right of the parent but still remains fully visible (no ...)
My current solution is the following below. The scenario b) is fine with mine, but in case of a) the problem is that the view 2 is moved to the right side of the parent and the 1 to the left side - both are short and there's pretty much space in between which looks odd. I want 2 to move to the further left (next to 1) and leave this space on the right side.
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_marginTop="1dp"
android:layout_weight="0.5">

android:layout_width="wrap_content"

Try doing this

Apparently, you want two scenarios which require to set a different orientation to the parent layout: first horizontal, second vertical. Maybe I'm wrong (and I hope so but) in static xml, there will be difficult to do this.
Try the code below to test if I'm wrong:
Scenario 1: orientation horizontal = the text 1 is not big enough
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="1dp"
android:orientation="horizontal" >
<TextView
android:id="#+id/textLong"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="left"
android:ellipsize="end"
android:singleLine="true"
android:textColor="#00a2ff"
android:textSize="18sp"
android:text="This is a normal text not big" />
<TextView
android:id="#+id/textShort"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right"
android:singleLine="true"
android:textColor="#00a2ff"
android:textSize="18sp"
android:text="short text" />
</LinearLayout>
Scenario 2: orientation vertical = the text 1 is too big
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="1dp"
android:orientation="vertical" >
<TextView
android:id="#+id/textLong"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="left"
android:ellipsize="end"
android:singleLine="true"
android:textColor="#00a2ff"
android:textSize="18sp"
android:text="This is a biiiggg loooonnng teeeeexxxxxtttt" />
<TextView
android:id="#+id/textShort"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right"
android:singleLine="true"
android:textColor="#00a2ff"
android:textSize="18sp"
android:text="short text" />
</LinearLayout>
To resolved your issue, you can try 2 solutions.
First, try to create a maxLenght limit, which calculate in your Activity and change the parent orientation of the LinearLayout. Get the number of chars that you have and display the orientation as well.
Second, customise your own class extend TextView. And create a getWidth method which return the width of the long TextView in comparison to it parent and change the orientation.
Maybe the following questions/answers could be useful (I think there are not solutions but more as inspiration):
In Android how to get the width of the Textview which is set to Wrap_Content
Get the size of a text in TextView
How to find android TextView number of characters per line?
Auto Scale TextView Text to Fit within Bounds
EDIT:
I found a solution with the last url that I writed above. See this answer where the dev wanted to make the same as you. So he decided to create a autoresizable textview. Take a look here: Move two side by side textviews to be one under another if text is too long
I hope this will help you.
May I suggest to use combination of LinearLayout and a little bit of coding. The idea is to have them side by side regardless of the size. and after the right textview is measured and laid out, set the max width of the left textview to whatever space left.
Here is the layout file, nothing special here:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<TextView
android:id="#+id/ns_in_txt"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:ellipsize="end"
android:gravity="top|left"
android:maxLines="1"
android:singleLine="true"
android:textColor="#00a2ff"
android:textSize="18sp" />
<TextView
android:id="#+id/ns_txt"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:ellipsize="none"
android:gravity="top|left"
android:maxLines="1"
android:singleLine="true"
android:textColor="#00a2ff"
android:textSize="18sp" />
</LinearLayout>
and add some codes to the activity/fragment:
final TextView tvLeft = (TextView) findViewById(R.id.ns_txt);
final TextView tvRight = (TextView) findViewById(R.id.ns_in_txt);
ViewTreeObserver obs = tvRight.getViewTreeObserver();
obs.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
#Override
public void onGlobalLayout() {
tvLeft.setMaxWidth(SCREEN_WIDTH - tvRight.getWidth());
}
});

Indent bullet list in TextView

I have a TextView which I fill with text from a string resources in strings.xml. The string resource contains < li > elements to create a bullet list inside the TextView. My problem is that I want to control the indention of lines in the bullet list that span over more than one line. Default the text isn't indented past the bullet so it looks kind of ugly. Is it possible to do this with style parameters or to create bullets in some other way?
Thanks in advance.
edit:
Is it really answered? I don't have any problems producing the bullet list, as described in those links but I'm having problems getting the layout correct. The indentation is like this:
text that go beyond the width
of the line.
And I want the "of the line" to at least start indented as far as the text after the bullet. That's what I try to achieve.
I'm suprised that there seems to be noone with this problem. I mean, bullet list can't be that uncommon in about-dialogs, FAQ etc and a bullet doesn't have to contain too much text to span more than one row and run into this problem.
Anyway, I got to solve it like this for now:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
android:id="#+id/ScrollViewTipsLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/TipsLayout"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TableLayout
android:layout_height="wrap_content"
android:id="#+id/TableLayout01"
android:layout_width="wrap_content"
>
<TableRow>
<TextView android:id="#+id/tvIngress"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="#+string/tv_picking_content_ingress"
android:layout_span="2"
android:singleLine="false"
android:layout_weight="1"
/>
</TableRow>
<TableRow>
<TextView android:id="#+id/tvCleaningDot1"
android:layout_height="wrap_content"
android:text="•"
android:singleLine="false"
/>
<TextView android:id="#+id/tvCleaningFirst"
android:layout_height="wrap_content"
android:text="#+string/tv_picking_content_first"
android:layout_width="0dp"
android:layout_weight="1"
android:gravity="left"
android:singleLine="false"
/>
</TableRow>
<TextView android:id="#+id/tvCleaningDot2"
android:layout_height="wrap_content"
android:text="•"
android:singleLine="false"
/>
<TextView android:id="#+id/tvCleaningSecond"
android:layout_height="wrap_content"
android:text="#+string/tv_picking_content_second"
android:layout_width="0dp"
android:layout_weight="1"
android:gravity="left"
android:singleLine="false"
/>
</TableRow>
</TableLayout>
</RelativeLayout>
I use it to present static text in a bullet list so I don't bother to create the bullet + text dynamically in code. If anyone have any suggestion how to accomplish the same thing in a better way, please enlight me.
Btw, if going with the solution suggested in second link above:
android:text="<ol><li>item 1\n</li><li>item 2\n</li></ol>
The second, third etc. row in a bullet that span over more than one row won't get same indention as first line, which is quite ugly.
Thank you #Bjorn
You can also do something like bellow.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawableLeft="#drawable/point"
android:textAppearance="?android:attr/textAppearanceSmall"
/>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Your Text Here"
android:textAppearance="?android:attr/textAppearanceSmall"
android:textSize="14sp" />
</LinearLayout>
The way I solved this problem was by using a RelativeLayout and marginLeft. The marginLeft will put a blank margin between it and the previous item.
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scrollbarTrackVertical="#drawable/scrollbar_vertical_track"
android:scrollbarThumbVertical="#drawable/scrollbar_vertical_thumb"
android:scrollbarSize="12dip">
<RelativeLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="10sp">
<TextView
android:id="#+id/body_text3"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:lineSpacingExtra="3sp"
android:text="Main paragraph of text, before the bulleted list"
android:textSize="15sp" />
<TextView
android:id="#+id/type1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:lineSpacingExtra="3sp"
android:text="• First bullet"
android:textSize="15sp"
android:layout_below="#+id/body_text3"
android:layout_marginLeft="25dp" />
<TextView
android:id="#+id/type2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:lineSpacingExtra="3sp"
android:text="• Second bullet"
android:textSize="15sp"
android:layout_below="#+id/type1"
android:layout_marginLeft="25dp" />
</RelativeLayout>
</ScrollView>
Just trying to point out the key answer of the question:
to create an bullet list, use TableLayout with two columns for each row. One column for TextView of a bullet and the other one for the text
to make text TextView fill the rest empty TableRow and indented at new line, set the weight to 1. You can set the bullet weight to zero or just simply not set the bullet weight and let it empty
based on my experience, changing width parameter do not affect the text and the bullet. So you can leave it empty or set it to anything you want.
Example:
<TableLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TableRow
android:id="#+id/tableRow1"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:id="#+id/bullet"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/bullet"/>
<TextView
android:id="#+id/TextView01"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="this is the text of a bullet list"/>
</TableRow>
</TableLayout>

Making EditText and Button same height in Android

I have an EditText and a Button in my LinearLayout and I want to align them closely together so they see seem to belong together (edittext + micButton for speech input).
Now they don't have the same height and they aren't really aligned well (Button seems to be a little lower than the EditText). I know I can apply a negative margin like -5dp to make them come closer together, but is there perhaps a better way to do this?
Set them in a specific container/layout so that they will automatically have the same height and no margin between them?
Using relative layout you can stretch a view depending upon another views size without knowing the exact size of the other view.
Here is the code :
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
>
<Button
android:layout_width="100dp"
android:layout_height="100dp"
android:text="button"
android:id="#+id/but"/>
<EditText
android:layout_width="100dp"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/but"
android:layout_alignBottom="#id/but"
android:layout_alignTop="#id/but"
/>
</RelativeLayout>
Check this link for reducing space between views :
https://groups.google.com/forum/?fromgroups#!topic/android-developers/RNfAxbqbTIk
Hmm, don't know why people bother so much with tables. Since the both Views are within a LinearLayout (presumable orientation=Horizontal), this command should center both within the layout:
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical" />
</LinearLayout>
Note: Since EditTexts and Buttons may orient their text slightly differently, you may have to do some tweaking (by changing margins or padding) to get the text to align properly.
I hope this solution might help for your scenario...Here is the code..
<RelativeLayout
android:id="#+id/rlLayout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="15dp"
android:orientation="horizontal"
android:padding="3dp" >
<EditText
android:id="#+id/etId"
android:layout_width="fill_parent"
android:layout_height="50dip"
android:background="#c8c8c8"
android:hint="Edittext"
android:paddingLeft="20dip"
android:paddingRight="10dip"
android:textColor="#000000" />
<RelativeLayout
android:id="#+id/rlLayoutid"
android:layout_width="50dp"
android:layout_height="50dp"
android:layout_alignRight="#+id/etId" >
<Button
android:layout_width="30dp"
android:layout_height="30dp"
android:layout_alignParentRight="true"
android:layout_marginRight="14dp"
android:layout_marginTop="10dp"
android:background="#drawable/calender" />
</RelativeLayout>
</RelativeLayout>
# Daniel Here You can use layout weight and weight sum
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:gravity="center"
android:weight_sum=2
>
<Button
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight=1
android:text="button"
android:id="#+id/but"/>
<EditText
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight=1
/>
</LinearLayout>
Android tries to automatically level everything off of the text and not the buttons themselves.
Took me forever to finally figure it out. Its really simple. Should fix it.
myButton.setGravity(Gravity.CENTER_VERTICAL);
or if they are in a row.. attach the buttons to a table row, then.
myTableRow.setGravity(Gravity.CENTER_VERTICAL);
