I want to use wrap_content on TextView where I keep only numbers (and coma), but I have noticed that this takes more space than needed (as if reserved space for letters).
Shown here:

Current situation - blue lines, desired - gray lines.
If it's not possible to do this with numbers and coma, maybe it is possible only with numbers?
This is my layout:
<?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="match_parent"

android:layout_width="wrap_content"
android:layout_height="wrap_content"

android:text="0,00"
android:textSize="50dp" />
</LinearLayout>
</LinearLayout>
</LinearLayout>
</FrameLayout>
</LinearLayout>
For example, MyTextView works as I wrote. The thing is that I want to center vertical my image, but it's not properly centered due to fact MyTextView takes more space than needed.
Set android:includeFontPadding to false, it is true by default. It will reduce the padding significantly although it does not remove it completely. Be sure to test this on a real device, since it had no effect for me in the layout preview. Set a background color to see the difference.
<TextView
...
android:includeFontPadding="false" />
Try it using textView.setTextSize(15dp);
I am using numbers in textView. I didnt feel it as a big issue.
Set height and width of the textview as wrap_content.Like,
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
are you using a custom font? If so, one possibility is that the padding you see is built into the font.
You can add this to your TextView: android:inputType="phone"

hello i am trying to wrap a textview that has a long text. but when i test it, it just goes beyond the screen. What im trying to do is it will go to the next line if the text is long and it automatically adjust the layout. I am using this in a listview.
i am referring to this old question Android TextView Text not getting wrapped, it works on him so i tried to implement it but it wont effect on mine. thanks for answering.
here's my XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:background="#e6e6e6"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="10dp">
<LinearLayout
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:orientation="vertical" android:padding="4dip"
android:layout_weight="1">
<TextView
android:id="#+id/tv_reviewer_name"
android:textSize="16sp"
android:textAppearance="?android:textAppearanceLarge"
android:text="Reviewer Name"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:layout_marginTop="5dp"
android:id="#+id/tv_review_details"
android:textSize="16sp"
android:textAppearance="?android:textAppearanceSmall"
android:text="Review"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:width="0dip"/>
</LinearLayout>
</LinearLayout>
UPDATE
here's my listview:
<ListView
android:divider="#android:color/transparent"
android:dividerHeight="2.0sp"
android:id="#+id/lv_reviews"
android:background="#f2f2f2"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
You can use the inputType to auto manage a multiline text.
<TextView
android:layout_marginTop="5dp"
android:id="#+id/tv_review_details"
android:textSize="16sp"
android:textAppearance="?android:textAppearanceSmall"
android:text="Review"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:width="0dip"
android:inputType="textMultiLine"
/>
if i use listView or recyclerView, i well put the layout width match parent as mentioned below:
<LinearLayout
<!--change to match_parent-->
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" android:padding="4dip"
android:layout_weight="1">
try it once, hope this will help you.
problem solved. it turns out android studio didnt update my changes when i ran my app. i uninstalled the app and then run it again and it works perfectly.
When you are using Gravity in vertical orientation, you have to use layout_height=0dp & when you are using Gravity in Horizontal orientation then you have to use layout_width=0dp for every child of Linear Layout so that it can resize the layout by itself
<LinearLayout
android:background="#e6e6e6"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="10dp">
<LinearLayout
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:orientation="vertical" android:padding="4dip"
android:layout_weight="1">
<TextView
android:id="#+id/tv_reviewer_name"
android:textSize="16sp"
android:textAppearance="?android:textAppearanceLarge"
android:text="Reviewer Name"
android:layout_width="wrap_content"
android:layout_height="0dp" />
<TextView
android:layout_marginTop="5dp"
android:id="#+id/tv_review_details"
android:textSize="16sp"
android:textAppearance="?android:textAppearanceSmall"
android:text="Review"
android:layout_height="0dp"
android:layout_width="match_parent"/>
</LinearLayout>
</LinearLayout>
I'm trying to place two TextViews side by side such that both are always on the screen.
They should always stay next to each other, touching borders. But the text keeps changing dynamically, so even if the text in the first TV becomes too long, it should not push the second TV off the screen.
Here's the basic layout:
<?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:layout_margin="10dp"
android:orientation="horizontal">
<TextView
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:background="#color/colorAccent"
android:padding="10dp"
android:text="Aa" />
<TextView
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:background="#color/colorPrimary"
android:padding="10dp"
android:text="Bb" />
</LinearLayout>
This is what it looks like:
However, if the text becomes long, the second TextView gets pushed off the screen.
I even tried the same thing using RelativeLayout.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="10dp">
<TextView
android:id="#+id/a"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#color/colorAccent"
android:padding="10dp"
android:text="Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/a"
android:background="#color/colorPrimary"
android:padding="10dp"
android:text="Bb" />
</RelativeLayout>
Still the same problem, the second TextView just won't stay on the screen. I want the first textView to get ellipsized, or convert into two lines without pushing the second TextView off the screen. But I also don't want the second TextView to be stuck to the right of the screen (this can be done by giving the first TextView a weight of 1)
PS: For me, the background of the Views is immaterial, so even if I can manage this by latching the view onto the right side of the screen, it's perfectly fine.
For this, I've tried using weights on both views in LinearLayout, and layout_alignParentRight in RelativeLayout - but without any success.
Edit:
If i use weights on both layouts - this is what it looks like:
<?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:layout_margin="10dp"
android:orientation="horizontal">
<TextView
android:id="#+id/a"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:background="#color/colorAccent"
android:padding="10dp"
android:layout_weight="1"
android:text="Aaa" />
<TextView
android:id="#+id/b"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:background="#color/colorPrimary"
android:padding="10dp"
android:text="Bbfbd" />
</LinearLayout>
This is fine if the text is long, but with short text, it defeats the purpose.
With long text it works perfectly.
Solution:
The only solution I could figure out was to define the maxWidth property for the first TextView. This property is defined in dimens.xml, with a different value for different screen sizes.
main.xml
<?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"
android:padding="10dp">
<TextView
android:id="#+id/a"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#color/colorAccent"
android:ellipsize="end"
android:maxLines="1"
android:maxWidth="#dimen/max_text_view_width"
android:padding="10dp"
android:text="Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa" />
<TextView
android:id="#+id/b"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#color/colorPrimary"
android:padding="10dp"
android:maxLines="1"
android:text="Bbbbbbb" />
</LinearLayout>
dimens.xml
<resources>
<dimen name="max_text_view_width">300dp</dimen>
</resources>
The Output for this looks like this:
TextView has a property of maxWidth . you can set that
programmatically
Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int width = size.x; //width of the screen
int height = size.y; // height of the screen
textView1.setMaxWidth(width/2);
textView2.setMaxWidth(width/2); //disable this if you want to have the rest of the screen by second textView
Now, textView will initially have the minimum size and will grow to
the maximum of the half size of the screen. You can customize this
with condition to fullfill your needs.
If it is ok for the textviews to be static you can leave them in LinearLayout and assign weight=1 to each of them. That way they are always going to stay the same.
For a much better and flexible solution use Google's flexbox layout. It is an awesome library where you can do all kinds of stuff.
Enter the below code and the problem will be solved:
<?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:weightSum="2"
android:orientation="horizontal"
android:layout_margin="10dp">
<TextView
android:id="#+id/a"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:background="#color/colorAccent"
android:padding="10dp"
android:scrollbars="vertical"
android:maxLines="2000"
android:text="Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa" />
<TextView
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/a"
android:background="#color/colorPrimary"
android:padding="10dp"
android:scrollbars="vertical"
android:layout_alignParentRight="true"
android:text="Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa" />
</LinearLayout>
This will definately works :
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:orientation="horizontal">
<TextView
android:layout_weight="1"
android:id="#+id/a"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#color/colorAccent"
android:padding="10dp"
android:text="Asssda" />
<TextView
android:layout_weight="1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/a"
android:background="#color/colorPrimary"
android:padding="10dp"
android:text="Bxdadsdc" />
</LinearLayout>
<?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:layout_margin="10dp">
<TextView
android:id="#+id/a"
android:layout_width="0dp"
android:layout_weight=".5"
android:layout_height="wrap_content"
android:background="#color/colorAccent"
android:padding="10dp"
android:text="wqkdnoqwndowqndowqowndowqndodnwqodnqow" />
<TextView
android:layout_width="0dp"
android:layout_weight=".5"
android:layout_height="match_parent"
android:background="#color/colorPrimary"
android:padding="10dp"
android:text="Aaaaaaaaainqwdiwdiwdniwqndiwqiwndiwqndiwqdniqwnnwiqdwoqndqowqndolnqwdlnaa\nkpaaaa" />
</LinearLayout>
Its not exaclty the solution but you should use this approach of using weights in linear layouts.
What could work is setting the maxWidth for the first View. You could set the maxWidth using xml resources for multiple screen sizes.
android:maxWidth="#dimen/max_width"
Then you could set max_width in dimens.xml
Giving each view an equal weight would make them occupy half the screen. That is not what you're looking for, I guess.
I think the best option here is to programmatically calculate the screen width of the device and set the max width of the first textView as a percentage of the screen width.
What finally worked for me was to set the maxWidth for the first View.
I set the maxWidth in the dimens xml and overridded the value for multiple screen sizes. It was difficult testing it out on multiple screens, but that's what finally worked for me.
android:maxWidth="#dimen/max_width"
I want to make the EditText and the OK button same height, but always got the EditText slightly shorter than the Button.
I googled and tried the following way without succeed, nothing changed:
set both the EditText and Button to same height in pixel
wrap EditText and Button into a RelativeLayout. Set the height of the RelativeLayout and set EditText and Button both to fillparent in height
set alignTop and alignBottom on the Button
The theme is: android:theme="#android:style/Theme.NoTitleBar.Fullscreen
Could someone please help me on this? Thanks!
Here is the xml:
<RelativeLayout android:id="#+id/login_layout_ipAddr"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:background="#CEE6F0"
android:visibility="invisible">
<RelativeLayout android:id="#+id/login_layout_inner_ipAddr"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<EditText android:id="#+id/login_text_ipAddr"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:inputType="text"
android:textSize="5pt"
android:hint="#string/login_text_ipAddr" />
<Button android:id="#+id/login_btn_ipAddr"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:background="#00ABDF"
android:textColor="#FFFFFF"
android:text="#string/login_btn_ipAddr"
android:onClick="updateIPaddr"/>
</RelativeLayout>
</RelativeLayout>
I have correct your code so try this one...
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
android:id="#+id/login_layout_ipAddr"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:background="#CEE6F0"
android:visibility="invisible">
<LinearLayout
android:id="#+id/login_layout_inner_ipAddr"
android:layout_width="match_parent"
android:layout_height="100dp"
android:orientation="horizontal"
android:weightSum="2">
<EditText
android:id="#+id/login_text_ipAddr"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_weight="1.8"
android:inputType="text"
android:textSize="5pt"/>
<Button
android:id="#+id/login_btn_ipAddr"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="0.2"
android:background="#00ABDF"
android:textColor="#FFFFFF"/>
</LinearLayout>
you can put both the edit text and the button in a TableRow and control their space with weight, it would make this process easier
Set padding to the button.
<Button android:id="#+id/login_btn_ipAddr"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:background="#00ABDF"
android:textColor="#FFFFFF"
android:text="#string/login_btn_ipAddr"
android:onClick="updateIPaddr"
android:paddingLeft="5dp"
android:paddingRight="5dp"/>
Try to use LinearLayout instead on RelativeLayout
<?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="fill_parent"
android:orientation="vertical"
android:layout_centerInParent="true">
<LinearLayout
android:id="#+id/login_layout_inner_ipAddr"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:background="#CEE6F0"
android:weightSum="6" >
<EditText
android:id="#+id/login_text_ipAddr"
android:layout_width="0dp"
android:layout_height="fill_parent"
android:layout_weight="5"
android:hint="#string/login_text_ipAddr"
android:inputType="text"
android:textSize="5pt" />
<Button
android:id="#+id/login_btn_ipAddr"
android:layout_width="0dp"
android:layout_height="fill_parent"
android:layout_weight="1"
android:background="#00ABDF"
android:onClick="updateIPaddr"
android:text="#string/login_btn_ipAddr"
android:textColor="#FFFFFF" />
</LinearLayout>
</LinearLayout>
Finally, I solved the problem by adding "android:background="#FFFFFF"" to the EditText element. But I've no idea what is the causes of such a behavior. I'd really appreciate if someone could shed some light on this.
No background:
With background:
Use following code :
<RelativeLayout android:id="#+id/login_layout_ipAddr"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:background="#CEE6F0"
android:visibility="invisible">
<RelativeLayout android:id="#+id/login_layout_inner_ipAddr"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<EditText android:id="#+id/login_text_ipAddr"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:inputType="text"
android:textSize="5pt"
android:drawableRight="#drawable/your_Button_image"
android:hint="#string/login_text_ipAddr" />
</RelativeLayout>
</RelativeLayout>
The default background of EditText has short padding. Buttons have these padding too! If you want to have an exact alignment, you can set your custom drawable background to each one. The most simple way is to set a solid color for the background.
To create a button with fixed height and width, you can give values in both px or in dp.
giving values in dp is more convenient , because android automatically scale the height and width in ldpi,mdpi and hdpi devices.
<Button
android:layout_width="100dp"
android:layout_height="50dp"
android:text="Click" />
I've got a TextView (text) overlaying my ImageView (image). My Problem ist that they do not have the same width. In other words - I want the red areas to appear white:
Here is my layout file so far:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#FFFFFF" >
<ImageView
android:id="#+id/image"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<TextView
android:id="#+id/text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Title"
android:padding="10dp"
android:textSize="25sp"
android:gravity="center"
android:background="#9988FF88"
android:textColor="#000000"/>
</RelativeLayout>
I am quite new to android and tried to add different tags to the textview like android:layout_alignLeft="#id/image" which couldn't fix it and also tried to configure the layout_width settings, but this didn't help me either. Also this solution couldn't solve it (I guess that is because of my android:layout_width="match_parent" in my ImageView). The solution was about adding these lines to the TextView:
android:layout_alignLeft="#+id/image"
android:layout_toRightOf="#+id/image"
I was also looking for programmatical solution, which also couldn't fix it:
image = (ImageView) findViewById(R.id.image);
text = (TextView) findViewById(R.id.text);
text.setWidth(image.getWidth());
Any ideas how to get rid of my red areas? Every idea will be appreciated and I would be happy about either an xml solution or a programmatical solution ! Thanks in advance :)
EDIT
I should specify that the image inside the ImageView does get replaced alot so that some images do fill the full horizontal screen in their width. So at some images there shall be a margin on the left and the right, but on others there shall not (in other words - the title shall always be as big as the image). (Btw: Thank you for your fast responses!)
UPDATE
I worked around this issue simply giving the header a white background color.
Try this
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_margin="26dp"
android:background="#FFFFFF" >
<ImageView
android:id="#+id/image"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="fitXY" />
<TextView
android:id="#+id/text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Title"
android:padding="10dp"
android:textSize="25sp"
android:gravity="center"
android:background="#9988FF88"
android:textColor="#000000"/>
</RelativeLayout>
The best solution I can think of is:
Cut the white bourders out of your image (You will then set some Margins in yout ImageView, to simulate the borders)
Then, change your layout so:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffffff"
>
<ImageView
android:id="#+id/image"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginLeft="16dp"
android:layout_marginRight="16dp"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
/>
<TextView
android:id="#+id/text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Title"
android:padding="10dp"
android:textSize="25sp"
android:gravity="center"
android:background="#9988FF88"
android:textColor="#000000"
android:layout_marginLeft="16dp"
android:layout_marginRight="16dp"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
/>
</RelativeLayout>
Your imageview is set to match_parent but there are still white areas around imageview. Are you sure your image doesn't have white areas around it?
Also, try using fill_parent instead of match_parent.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#FFFFFF"
android:orientation="horizontal">
<LinearLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"/>
<RelativeLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="8">
<ImageView
android:id="#+id/image"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<TextView
android:id="#+id/text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Title"
<!--android:padding="10dp" -->
android:textSize="25sp"
android:gravity="center"
android:background="#9988FF88"
android:textColor="#000000"/>
</RelativeLayout>
<LinearLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"/>
</LinearLayout>
A custom Dialog box with a RelativeLayout contains a Button widget that won't change its margins, regardless of direction. Here's the xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="match_parent"
android:orientation="horizontal" android:background="#99000000">
<TextView android:id="#+id/dialogtitle" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:text="Some text" />
<TextView android:id="#+id/dialogtext" android:layout_width="300dp"
android:layout_height="wrap_content" android:textSize="15dp"
android:layout_alignParentLeft="true" android:layout_below="#id/dialogtitle"
android:paddingLeft="8dp" />
<Button android:id="#+id/dialogbuttoninfo" android:layout_width="80dp"
android:layout_height="wrap_content" android:text="Doesn't care about margins"
android:layout_alignParentRight="true" android:layout_marginLeft="128dp" />
</RelativeLayout>
Padding works but only moves the text inside the button. Any suggestions?
This seems crappy but have you tried putting it all in a LinearLayout instead? or perhaps removing android:orientation="horizontal". I dont think RelativeLayout cares about orientation from what I've seen. Also I think, but might be wrong, that if you do a LinearLayout then you won't need to have android:layout_alignParentLeft="true" in there either.
After cleaning it up a bit (sorry but its so hard to read when its compressed as it was in the question) you also didn't state where the last TextView , dialogbuttoninfo was supposed to be relative to everything else, I think you have to do that for Relative layouts to behave properly, I've had some squirrely things happen.

You may need to align the left of the button against something before the margin has real meaning.
