Android TextView new line isn't working

I found the Answer I will accept it in 2 days time

I have been trying to create an activity that can display multiple messages for the user, in order to fit everything in the text view I need to create three lines. My search online hasn't given me any solutions, here is what I have tried

Java

"\n"
"\r\n"
newLineChar = System.getProperty("line.separator")
messageTextView.setText(Html.fromHtml("This\n Is\n A Test"));
messageTextView.setText(Html.fromHtml("This<br> Is<br> A Test"));

xml

android:lines="3"
android:maxLines="3"

Misc.

Code snippet:

// Message passed to next activity via putExtra()
message = "This\n Is\n A Test";
// Next Activity
TextView messageTextView = (TextView) findViewById(R.id.messageToUser);
String message = getIntent().getStringExtra("message");
messageTextView.setText(message);

Current and Updated XML for the TextView:

<TextView
    android:id="@+id/messageToUser"
    android:layout_width="0dp"
    android:layout_height="200dp"
    android:background="#90FFFFFF"
    android:ems="10"
    android:fontFamily="serif"
    android:text=""
    android:textAlignment="center"
    android:textColor="@android:color/black"
    android:textSize="30sp"
    android:textStyle="bold"
    tools:layout_constraintTop_creator="1"
    tools:layout_constraintRight_creator="1"
    android:layout_marginStart="165dp"
    android:layout_marginEnd="165dp"
    app:layout_constraintRight_toRightOf="parent"
    android:layout_marginTop="209dp"
    tools:layout_constraintLeft_creator="1"
    app:layout_constraintLeft_toLeftOf="parent"
    app:layout_constraintTop_toTopOf="parent" />

If this helps, I'm on Windows 7, Android Studio 2.3.2, Java 1.8, designing an App Specifically for SM-T580 (Samsung Tab A 10.1"), the TextView's parent is the base ConstraintLayout of the component tree

Found the issue I had to take android:inputType="textPersonName" out of the XML for the TextView. I had mistakenly left the Html.fromHtml(...) method call when I initially removed android:inputType="textPersonName". After calling message.setText("This\n Is\n A Test"); with NO android:inputType="textPersonName".Everything worked as expected.

For final clarity....

The newline character "\n" will not work if the input type is "textPersonName"

The newline character for Andriod is "\n"

There is no need to set for the android:inputType because this is a TextView. These are the steps that I did to successfully implement the new line:

  1. Make sure that android:maxLine is not set to 1. If you set this to 1, it will not implement new line. [Refer to the screenshot]

set maxLine inside xml file

  1. If you want to manipulate a string that is not constant or not declared inside your string.xml, put System.getProperty("line.separator") between two string. In my case I put

    phoneNumber = memberProfile.getPhoneNumber() + System.getProperty("line.separator") + "09162343636";

  2. If you have a constant string or you have set it to your string.xml file, just put "\n" and that works perfectly. Refer sample below:

    string.xml

I was using a recyclerView to display so here is the output of this:

This works for me:

messageTextView.setText(Html.fromHtml("This<br/>Is<br/>A Test"));

Explanation: The TextView content is HTML content. <br/> is an HTML tag for a line break.

Add this code to res/strings

<string name="myhtml">
<![CDATA[
<p>This is a <b>bold</b> and <i>italic</i> text</p>
<p>This is another paragraph of the same string.</p>
]]>
</string>

Add this your Activity class

TextView tv = (TextView)findViewById(R.id.foo);
tv.setText(Html.fromHtml(getString(R.string.myhtml)));

try this \n corresponds to ASCII char 0xA, which is 'LF' or line feed

        tv.setText("First line " + System.getProperty("line.separator") + "Line 2"+ System.getProperty("line.separator") + "Line 3");


String String1 = "value 1";
String String2 = "value 2";
TextView.setText(String1 + "\n" + String2);

or try this

string = string.replace("\\\n", System.getProperty("line.separator"));

for hardcore string try this 

<string name="value"> This\nis a sample string data</string>

or 

<string name="value> This<br>is a sample<br> String data</string>

\r\n works for me 

messageTextView.setText("First line\r\nNext line");

Or alterantively you can also use string variable

<string name="sample_string"><![CDATA[some test line 1 <br />some test line 2]]></string>

so wrap in CDATA is necessary and breaks added inside as html tags
