Android TextView Text wont wrap on Listview

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>

Android layout objects placement

I have this simple activity in my android app but I don't know how to place my button so it appears at the same position on various screen sizes.
I want the button to always be placed at the bottom of the screen. The screenshot shown is from a phone screen. When displayed on a larger screen the button is higher up.
How can I fix this?
Thanks
See this screenshot

You can use RelativeLayout with this parameter (android:layout_alignParentBottom="true")
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:text="Click Me!"/>
</RelativeLayout>

You should use a RelativeLayout
If you have a RelativeLayout that fills the whole screen you should be able to use android:layout_alignParentBottom to move the button to the bottom of the screen.
If your button at the bottom doesn't show then probably the layout above it takes all the space. In this case you can put the button first in your layout file and position the rest of the layout above the views with android:layout_above.

Have a look a RelativeLayout. Use this ViewGroup and add a Button inside it with alignParentBottom
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
<Button
android:id="#+id/button_id"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:alignParentBottom="true"
android:text="HORAIRE"
android:layout_margins="<your_margin_in_dp>" />
</RelativeLayout>

Make footerButton.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/footer"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:gravity="center" >
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="5dp"
android:text="HORAIRE"
android:textColor="#ffffff"
android:textSize="20sp" />
</RelativeLayout>
And add it in all your layout file like below line:
Android Activity_Layout
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<!-- Footer aligned to bottom -->
<include layout="#layout/footer" />
<!-- Content above footer -->
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="#id/footer"
android:layout_below="#id/header"
android:gravity="center">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Content goes here"
android:textColor="#FFFFFF"
android:textSize="20sp" />
</RelativeLayout>
</RelativeLayout>
Hope it will solve your problem

How to add space between two textviews

I am new to android development and I was just wondering how can I add space between two TextViews? Any help would be appreciated.
The code I have written so far
<?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="fill_parent"
android:orientation="vertical" >
<TextView
android:id="#+id/lbl_group_coworkers"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Coworkers" />
<TextView
android:id="#id/lbl_group_"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Family"/>
</LinearLayout>

You can use android:layout_marginTop="value"
like this
<?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="fill_parent"
android:orientation="vertical" >
<TextView
android:id="#+id/lbl_group_coworkers"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Coworkers" />
<TextView
android:id="#id/lbl_group_"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="20dp"
android:text="Family"/>
</LinearLayout>

you can have margin between two textview.
add top margin to the second textview
like this
<TextView
android:id="#id/lbl_group_"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="20dp"
android:text="Family"/>

Just replace <LinearLayout> </LinearLayout>
with <RelativeLayout> </RelativeLayout>
then go in graphical layout and adjust space as you like.

add margin left right top bottom
android:layout_marginLeft="10dp"

try adding margin
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView
android:id="#+id/lbl_group_coworkers"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Coworkers"
android:layout_margin="10dp"/>
<TextView
android:id="#+id/lbl_group"
android:layout_margin="10dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Family"/>
</LinearLayout>

You can use
android:layout_margin="5dp"
or
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
android:layout_marginTop="5dp"
android:layout_marginBottom="5dp"
But before you ask a lot more such questions, I'd suggest to read through the android dev guides ( http://developer.android.com/guide/components/fundamentals.html )
Good Luck and have fun developing...

You can use either padding or margin depending on what you need, here is a link of a guy who gives a good explanation between the two that will help you decide on which one you'd like to use: android margin vs padding

add android:layout_marginRight="..." to the first textView

set margin property in TextView...
android:layout_marginTop="20dp"
android:layout_marginRight="20dp"
android:layout_marginBottom="20dp"
android:layout_marginLeft="20dp"
and if all side set space then...
android:layout_margin="20dp"

Use GridLayout instead of LinearLayout
<GridLayout
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:text="A"
android:layout_gravity="left" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="B"
android:layout_gravity="right" />
</GridLayout>

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/custom_border"
>
<TextView
android:text="#string/textView_reference_number"
style="#style/CustomTextView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/textView_refernce_number_label"
/>
<TextView
android:text="Reference Number Value"
style="#style/CustomTextView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/textView_refernce_number"
android:layout_marginTop="10dp"/>
</LinearLayout>
android:layout_marginTop XML attribute is used to specify extra space on the top side of this view. Thus android:layout_marginTop="10dp" on 2nd textView is specifying 10 dp of space between it and above view. #UDI Please refer below link for more details over the same https://developer.android.com/reference/android/view/ViewGroup.MarginLayoutParams.html

How to center a textview inside a linearlayout

I have the following layout i'd like to make the textview appear in the center and middle of the view. How can i acheive this?
I've tried adjusting the various gravity attributes when looking at the layout in graphical view, but nothing seems to change it. I'd like the textview in the center which i've done but halfway down the view.
thanks matt.
<?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:orientation="vertical"
android:background="#drawable/carefreebgscaledalphajpg" >
<TextView
android:id="#+id/textviewdatefornocallspage"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="You have no calls for "
android:textSize="25sp" />
</LinearLayout>

set the gravity to center in your linearLayout tag :
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:gravity="center"
android:background="#drawable/carefreebgscaledalphajpg" >
or use a RelativeLayout like this :
<?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:background="#drawable/carefreebgscaledalphajpg" >
<TextView
android:id="#+id/textviewdatefornocallspage"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="You have no calls for "
android:textSize="25sp" />
</RelativeLayout>

Try this
simple i have tried to many answer but all answers are not working ......finally this methods works for me
<LinearLayout
android:layout_below="#+id/iv_divider"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_marginTop="#dimen/_10dp">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/mycredits"
android:textColor="#color/colorGray"
android:gravity="center"
android:textSize="#dimen/_25dp" />
</LinearLayout>

Set android:gravity="center" attribute for TextView inside linear layout and keep the text view's height and width as wrap_content.
This Solution worked for me.

<TextView
...
android:layout_gravity="center"
....
/>

Set width of your textview to wrap_content, and set your LinearLayout to
android:gravity="center_horizontal"

Add android:gravity="center_horizontal" to your LinearLayout and alter your TextView's layout_width as android:layout_width="wrap_content"
<?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:orientation="vertical"
android:gravity="center_horizontal"
android:background="#drawable/carefreebgscaledalphajpg" >
<TextView
android:id="#+id/textviewdatefornocallspage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:text="You have no calls for "
android:textSize="25sp" />
</LinearLayout>

None of the other answers worked for me. I had to use android:textAlignment="center"
My layouts were as follows
<LinearLayout...
<RelativeLayout...
<RelativeLayout....
<TextView
android:layout_centerInParent="true"
android:textAlignment="center"

If in linearlayout your orientation vertical, you can put the textview in the "horizontal center" by android:layout_gravity="center". For centering textview vertically you need to set layout_height of textview to match_parent and set android:gravity to "center". If you want to use more than one view in this layout, you should use RelativeLayout and set
android:layout_centerInParent="true".

<LinearLayout
android:id="#+id/service_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/card_view"
android:layout_marginTop="10dp"
android:background="#color/app_bar_background"
android:orientation="vertical">
<TextView
android:id="#+id/list_title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fontFamily="sans-serif"
android:gravity="center"
android:singleLine="true"
android:text="#string/Services"
android:textColor="#color/app_bar_text"
/>
</LinearLayout>

Sounds like you want android:layout_gravity for the TextView
see docs: developer.android.com

set android:gravity="center" in your Linear Layout

<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".view.fragments.FragmentAncRecords">
<TextView
android:id="#+id/tvNoDataFound"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fontFamily="#font/poppins_regular"
android:visibility="visible"
android:gravity="center"
android:text="#string/no_record_available"
/>
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/rvAncRecords"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:visibility="gone"
app:layoutManager="androidx.recyclerview.widget.LinearLayoutManager" />
</LinearLayout>

center your texteView in RelativeLayout :
<?xml version="1.0" encoding="utf-8"?>
<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="match_parent"
tools:context=".MainActivity">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true"
/>
</RelativeLayout>

Use Relative Layout, it always gives more accurate and flexible layout
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ImageView
android:id="#+id/imageView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:src="#drawable/ic_launcher" />
</RelativeLayout>

Center list item vertically on ListView

I'm developing an Android application.
On one activity I have a List with list items. Those list items will have a TextView (I'm using my own layout because probably I will need to add more widgets to it).
This is ListActivity 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="match_parent"
android:orientation="vertical" >
<ListView
android:id="#android:id/list"
android:layout_width="match_parent"
android:layout_height="469dp"
android:layout_marginLeft="20dp"
android:layout_marginRight="20dp"
android:layout_marginTop="40dp">
</ListView>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<TextView
android:id="#+id/orderErrorMsg"
android:layout_alignParentRight="true"
android:layout_alignParentBottom="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="10dp"
android:textSize="16dp" >
</TextView>
</RelativeLayout>
</LinearLayout>
And this is ListItem 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="100dp"
android:orientation="vertical">
<TextView
android:id="#+id/orderToFillName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:textSize="20dp" />
</LinearLayout>
And, finally, this is the result:
Why TextView is not centered vertically?

You have "wrap_content" on the layout_height of the TextView = there is no space to center vertically on since the TextView is wrapped tightly.
Try changing the layout_height to "match_parent" or place gravity="center_vertical" attribute in the LinearLayout instead.
<TextView
android:id="#+id/orderToFillName"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="center_vertical"
android:textSize="20dp" />

the answer is really simple: you have to add this to your TextView's XML:
android:gravity="center"
Currently you're not setting the text's position in the TextView but just the View's position.
Best wishes,
Tim

Try this way:
<TextView
android:id="#+id/orderToFillName"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:gravity= "center_vertical|center_horizontal"
android:textSize="20dp" />
or
android:gravity="center"
