TextView Alignment Issue on Android

I am having two TextView in LinearLayout.
<LinearLayout
android:layout_marginTop="-10dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:id="#+id/product_discounted_price"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginStart="#dimen/activity_vertical_margin"
android:layout_marginEnd="#dimen/margin_between_prices"
android:drawablePadding="5dp"
android:gravity="center_vertical"
android:text="AED200000000.00"
android:textColor="#color/black"
android:textSize="#dimen/font_size_sub_normal"
android:visibility="visible" />
<TextView
android:id="#+id/product_unit_price"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginRight="#dimen/activity_vertical_margin"
android:drawablePadding="5dp"
android:gravity="center_vertical"
android:text="AED200000000000.00"
android:textSize="#dimen/font_size_emphasized"
android:visibility="visible" />
</LinearLayout>
I want something like if 2nd TextView doesnt come in single line than it should shift to second line.
Issue is :
With SingeLine=true
With maxLine=1
What I want :

change
android:orientation="horizontal"
to
android:orientation="vertical"
and also add maxline and singleline to textView

It is easy put your text views in a RelativeLayout and all you need to set layout_above or layout_bottom for your TextViews
or you can change orientation:vertical and then the gravity works.
You can also set layout_gravity

Space between textview and drawable icon

I'm facing problems with the position of an icon. I've set that icon as drawableLeft of a TextView, this is working fine but, if I set the TextView's gravity to center_horizontal, then a padding space appears between the icon and the text. The code is as follows:
<TextView
style="#style/BaseText.White.Bold"
android:gravity="center_horizontal"
android:drawableStart="#drawable/ic_text"
android:drawableLeft="#drawable/ic_text"
android:text="#string/text"
android:layout_marginBottom="#dimen/margin_small"
android:layout_marginRight="#dimen/margin_big"
android:layout_marginLeft="#dimen/margin_big"
android:padding="0dp"
android:drawablePadding="0dp"/>
What do I have to do to ensure that the icon is shown at the text's left side but horizontally centered?
I've make two screenshots to show you the difference when adding or removing the icon's gravity.
When the textview's gravity is not set, the result is as follows:
But, when the gravity is added, then a padding appears between the text and the icon:
Thanks in advance

Only add android:drawablePadding="10dp" field in your text view refer the coad
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Add New Address"
android:textAppearance="#style/Title"
android:id="#+id/tvAddNewAddress"
android:drawablePadding="20dp"
android:layout_weight="1"
android:padding="5dp"
android:textColor="#color/colorAccent"
android:drawableStart="#android:drawable/arrow_down_float"
/>

Try to give android:gravity="center" to Text View. Also add android:layout_width="wrap_content" and android:layout_height="wrap_content" properties in Text View.
Refer 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">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_marginBottom="5dp"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
android:drawableLeft="#mipmap/ic_launcher"
android:drawablePadding="0dp"
android:drawableStart="#mipmap/ic_launcher"
android:gravity="center"
android:textSize="22sp"
android:padding="0dp"
android:text="TestingTestingTestingTestingTestingTestingTestingTestingTesting" />
</RelativeLayout>
This is what it showing.

RelativeLayout View to right of TextView

I got following simple Layout. The problem can be reproduced in the android studio designer:
<?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">
<TextView
android:id="#+id/x"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_marginEnd="#dimen/margin_small"
android:layout_marginRight="#dimen/margin_small"
android:text="#string/long_string"
android:textAppearance="?android:attr/textAppearanceSmall"/>
<CheckBox
android:id="#+id/y"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#+id/x"
android:layout_toEndOf="#+id/x"
android:layout_centerVertical="true" />
</RelativeLayout>
This layout works fine if the text length of the textview is short. The checkbox is placed on the right of the textview. But if the text gets long and even wraps maybe, then the checkbox is pushed out of the view. It is not visible anymore. I would like that the checkbox is always visible on the right of the textview even, if it fills the whole width of the screen.
I tried to rewrite the layout with a LinearLayout which doesn't work either.
<?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="horizontal">
<TextView
android:id="#+id/x"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginEnd="#dimen/margin_small"
android:layout_marginRight="#dimen/margin_small"
android:text="#string/long_string"
android:textAppearance="?android:attr/textAppearanceSmall"/>
<CheckBox
android:id="#+id/y"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
</LinearLayout>
Do you know a trick to to achieve this with relative layout? I would somehow expect this behaviour from relative layout by default. Thanks ;)

This is working for me: make checkBox alignParentRight and make TextView toLeftOf it:
<?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">
<TextView
android:id="#+id/x"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_toLeftOf="#+id/y"
android:text="This is very-very-very looooooooooooong stringgggg, very-very, long-long"
android:textAppearance="?android:attr/textAppearanceSmall"/>
<CheckBox
android:id="#+id/y"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_alignParentRight="true"/>
</RelativeLayout>
Edit. You can include this Relative Layout into other (parent) layout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:gravity="left">
<TextView
android:id="#+id/x"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_toLeftOf="#+id/y"
android:text="this is veryyyyy yyyyyyyyyy yyyyyy yyy loooooo oooooooo ooon nnggggg gggg striiii iiiiin gggggg ggggg ggggggg ggg"
android:textAppearance="?android:attr/textAppearanceSmall"/>
<CheckBox
android:id="#+id/y"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
android:layout_centerVertical="true" />
</RelativeLayout>
</RelativeLayout>
It's also working. If you put android:gravity="left" into Relative layout, it will locate its content on the left side.

One way out would be to put the textview and checkbox in a linear layout with orientation horizontal. Set width of checkbox to be whatever you want (a constant) and the width of textbox to be 0dp and layout_weight of 1.

You should put the property layout_weight to make your views (TextView and Checkbox) have a deff space in the screen instead of use a hard value
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<TextView
android:id="#+id/x"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="0.9"
android:layout_marginEnd="#dimen/margin_small"
android:layout_marginRight="#dimen/margin_small"
android:text="#string/long_string"
android:textAppearance="?android:attr/textAppearanceSmall"/>
<CheckBox
android:id="#+id/y"
android:layout_weight="0.1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
</LinearLayout>

I guess the desired layout is not possible by default. I tried to do this using RelativeLayout, LinearLayout and TableLayout. It is technically understandable that the these layout do not support that behaviour. The relative layout would have to explicitly respect the case that an element on the left or right is minimal visible inside the parent even it is placed to left or right. Another solution would be if the table layout would allow a column to consume the rest of the space but respects min width of other columns as well.
For my case i wrote a workaround. I used the initial relative layout of my question but set a max width to the textview using following calculation:
DisplayMetrics displaymetrics = new DisplayMetrics();
context.getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
int displayWidth = displaymetrics.widthPixels;
That guarantees the checkbox to be visible. I know the solution could be hardly possible in scenarios where the given layout is embedded in a more complex layout.

Separate padding values for checkbox and text inside CheckedTextView

Im trying to build my multiple choice layout according to latest material design guidelines with CheckedTextView widget. But I can't find the way to set left padding for checkbox and textview separately (16dp for icon, 72 for text).
The most acceptable solution i could find is to use android:drawablePadding attribute but i think it is not quite right.
Is it possible to set padding values separately inside CheckedTextView?
<?xml version="1.0" encoding="utf-8"?>
<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/text1"
android:layout_width="match_parent"
android:layout_height="48dp"
android:gravity="center_vertical"
android:textSize="16sp"
android:textColor="#000000"
android:paddingLeft="16dp"
android:drawableLeft="?android:attr/listChoiceIndicatorMultiple"
android:drawablePadding="36dp"/>

Try this, it work for me, add a "padding" property:
<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/text1"
android:background="#color/grey"
android:textColor="#color/white"
android:singleLine="true"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="10dp"
android:ellipsize="marquee"/>

Try this one: (This is under RelativeLayout)
<CheckedTextView
android:id="#+id/checkedTextView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:paddingStart="16dp"
android:paddingEnd="16dp"
android:text="#string/text"
android:checkMark="?android:attr/textCheckMark"
android:checked="false" />
It will stay like this:
Layout:
| |
| Text for checkedTextView: V |
| |

I'm late to the party, but just in case someone is looking for a solution, here is how I did it using the CheckBox widget:
<CheckBox
android:id="#+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView"
android:minHeight="30dp"
android:textColor="#ffffff"
android:layout_centerVertical="true"
android:layout_marginStart="16dp"
android:paddingStart="56dp"/>
android:layout_marginStart="16dp" sets margin to both icon and text, while android:paddingStart="56dp" sets padding between text and icon.

How do I center text horizontally and vertically in a TextView?

How do I center the text horizontally and vertically in a TextView, so that it appears exactly in the middle of the TextView in Android?

I'm assuming you're using XML layout.
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:text="#string/**yourtextstring**"
/>
You can also use gravity center_vertical or center_horizontal according to your need.
As #stealthcopter commented, in java: .setGravity(Gravity.CENTER);.
And for Kotlin users, .gravity = Gravity.CENTER

android:gravity="center"
This will do the trick

You can also set it up dynamically using:
textView.setGravity(Gravity.CENTER_VERTICAL | Gravity.CENTER_HORIZONTAL);

android:layout_centerInParent="true"
This works when used with a RelativeLayout where the layout's height & width are set to wrap_content.

You can also use the combination:
android:gravity="left|center"
Then, if textview width is more than "fill_parent" the text will still be aligned to left (not centered as with gravity set only to "center").

Apply gravity:
TextView txtView = (TextView) findViewById(R.id.txtView);
txtView.setGravity(Gravity.CENTER_HORIZONTAL);
For vertical:
txtView.setGravity(Gravity.CENTER_VERTICAL);
In XML:
<TextView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center"
android:text="#string/Hello_World"
/>

There are two ways of doing this.
The first in the XML code. You need to pay attention at the Gravity Attribute. You also can find this attribute in the Graphic Editor; it may be easier than the XML EDITOR.
<TextView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center_vertical|center_horizontal"
android:text="Your Text"
/>
For your specific scenario, the values of gravity will be:
center_vertical|center_horizontal
In the graphical editor you will find all the possible values, even see their results.

If you are using TableLayout make sure to set the gravity of the TableRows to center, too.
Otherwise it will not work. At least it didn't work with me until I set the gravity of the TableRow to center.
For example, like this:
<TableRow android:id="#+id/tableRow2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center">
<TextView android:text="#string/chf" android:id="#+id/tv_chf" android:layout_weight="2" android:layout_height="wrap_content" android:layout_width="fill_parent" android:gravity="center"></TextView>
</TableRow>

You need to set TextView Gravity (Center Horizontal & Center Vertical) like this:
android:layout_centerHorizontal="true"
and
android:layout_centerVertical="true"
And dynamically using:
textview.setGravity(Gravity.CENTER);
textView.setGravity(Gravity.CENTER_VERTICAL | Gravity.CENTER_HORIZONTAL);

In my opinion,
android:gravity="center"
is better than,
android:layout_centerInParent="true"
which is better than,
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
at least for formatting text.

For Linear Layout:
In XML use something like this
<TextView
android:id="#+id/textView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center_vertical|center_horizontal"
android:text="Your Text goes here"
/>
To do this at run time use something like this in your activity
TextView textView1 =(TextView)findViewById(R.id.texView1);
textView1.setGravity(Gravity.CENTER_VERTICAL | Gravity.CENTER_HORIZONTAL);
For Relative Layout: in XML use some thing like this
<TextView
android:id="#+id/textView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_centerInParent="true"
android:text="Your Text goes here"
/>
To do this at run time use something like this in your activity
TextView textView1 =(TextView)findViewById(R.id.texView1);
RelativeLayout.LayoutParams layoutParams = RelativeLayout.LayoutParams)textView1.getLayoutParams();
layoutParams.addRule(RelativeLayout.CENTER_IN_PARENT, RelativeLayout.TRUE);
textView1.setLayoutParams(layoutParams);

Use in the XML file.
Layout file
<TextView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center"
android:text="#string/stringtext"/>
or:
Use this inside the Java class
TextView textView =(TextView)findViewById(R.id.texviewid);
textView.setGravity(Gravity.CENTER_VERTICAL | Gravity.CENTER_HORIZONTAL);

Use this for relative layout
android:layout_centerInParent="true"
and for other layout
android:gravity="center"

If the TextView's height and width are wrap content then the text within the TextView always be centered. But if the TextView's width is match_parent and height is match_parent or wrap_content then you have to write the below code:
For 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="match_parent">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="Hello World" />
</RelativeLayout>
For LinearLayout:
<?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">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="Hello World" />
</LinearLayout>

While using gravity works for TextView, there's an alternate method implemented in API level 17 -
textView.setTextAlignment(View.TEXT_ALIGNMENT_CENTER);
Don't know the difference, but it works too. However only for API level 17 or higher.

In RelativeLayout, it will be nice with it.
And another Button and anything else you can add.
The following works nicely for me.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#ff314859"
android:paddingLeft="16dp"
android:paddingRight="16dp">
<TextView
android:id="#+id/txt_logo"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="your text here"
android:textSize="30dp"
android:gravity="center"/>
...other button or anything else...
</RelativeLayout>

Use android:textAlignment="center"
<TextView
android:text="HOW WAS\nYOUR\nDAY?"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAlignment="center"
android:id="#+id/textView5"
/>

Easiest way (which is surprisingly only mentioned in comments, hence why I am posting as an answer) is:
textview.setGravity(Gravity.CENTER)

You can just set the gravity of your textview into CENTER.

TextView gravity works as per your parent layout.
LinearLayout:
If you use LinearLayout then you will find two gravity attribute
android:gravity & android:layout_gravity
android:gravity : represent layout potion of internal text of TextView while
android:layout_gravity : represent TextView position in parent view.
If you want to set text horizontally & vertically center then use below code this
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="300dp"
android:background="#android:color/background_light"
android:layout_height="300dp">
<TextView
android:layout_width="match_parent"
android:text="Hello World!"
android:gravity="center_horizontal"
android:layout_gravity="center_vertical"
android:layout_height="wrap_content"
/>
</LinearLayout>
RelativeLayout:
Using RelativeLayout you can use below property in TextView
android:gravity="center" for text center in TextView.
android:gravity="center_horizontal" inner text if you want horizontally centered.
android:gravity="center_vertical" inner text if you want vertically centered.
android:layout_centerInParent="true" if you want TextView in center position of parent view.
android:layout_centerHorizontal="true" if you want TextView in horizontally center of parent view.
android:layout_centerVertical="true" if you want TextView in vertically center of parent view.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="300dp"
android:background="#android:color/background_light"
android:layout_height="300dp">
<TextView
android:layout_width="match_parent"
android:text="Hello World!"
android:gravity="center"
android:layout_centerInParent="true"
android:layout_height="wrap_content"
/>
</RelativeLayout>

If you are trying to center text on a TableRow in a TableLayout, here is how I achieved this:
<TableRow android:id="#+id/rowName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="5dip" >
<TextView android:id="#+id/lblSomeLabel"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center"
android:layout_width="0dp"
android:layout_weight="100"
android:text="Your Text Here" />
</TableRow>

If you are using Relative Layout:
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/stringname"
android:layout_centerInParent="true"/>
If you are using LinearLayout
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/stringname"
android:layout_gravity="center"/>

Try this way,it will work
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:gravity="center">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAlignment="center"/>
</LinearLayout>

Here is my answer that I had used in my app. It shows text in center of the screen.
<TextView
android:id="#+id/txtSubject"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/subject"
android:layout_margin="10dp"
android:gravity="center"
android:textAppearance="?android:attr/textAppearanceLarge" />

The TextView's height and width are wrap content then the text within the textview always be centered, then make center in its parent layout by using:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="Hello.."/>
</RelativeLayout>
For LinearLayout also the code is same :
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello.."/>
</LinearLayout>
and pro-grammatically parent is RelativeLayout java code this at run time use something like this in your activity
TextView textView1 =(TextView)findViewById(R.id.texView1);
RelativeLayout.LayoutParams layoutParams = RelativeLayout.LayoutParams)textView1.getLayoutParams();
layoutParams.addRule(RelativeLayout.CENTER_IN_PARENT, RelativeLayout.TRUE);
textView1.setLayoutParams(layoutParams);

Actually, we can do better by excluding fontPadding.
<TextView
android layout_height="wrap_content"
android layout_height="wrap_content"
android:includeFontPadding="false"
android:textAlignment="center"
/>

As many answers suggest above works fine.
android:gravity="center"
If you want to center it just vertically:
android:gravity="center_vertical"
or just horizontally:
android:gravity="center_horizontal"

Simply, in your XML file, set the textview gravity to center:
<TextView
android:gravity="center" />

android:gravity="center_horizontal" for align text Center horizontally.
android:gravity="center_vertical" for align text Center vertically.
android:gravity="center" for align text Center both vertically and horizontally.
<TextView
android:layout_width="match_parent"
android:gravity="center_horizontal|center_vertical"
android:layout_height="match_parent" />

You can do like this to get text centered
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center" />
