You have to use SpannableString for that :
String mystring=new String("Hello.....");
SpannableString content = new SpannableString(mystring);
content.setSpan(new UnderlineSpan(), 0, mystring.length(), 0);
yourtextview.setText(content);
Update : You can refer my answer on Underling TextView's here in all possible ways.

Following are the some approaches for underlined text in android:
1st Approach
You can define your string in strings.xml
<string name="your_string"><u>Underlined text</u></string>
And use that string in your xml
file
<TextView
android:id="@+id/txt_underlined"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:text="@string/your_string"/>
Or you can use that string in your Activity/Fragment
txtView.setText(R.string.your_string);
2nd Approach
To underline the text in TextView, you can use SpannableString
String text="Underlined Text";
SpannableString content = new SpannableString(text);
content.setSpan(new UnderlineSpan(), 0, text.length(), 0);
txtView.setText(content);
3rd Approach
You can make use of setPaintFlags method of TextView to underline the text of TextView.
txtView.setPaintFlags(mTextView.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);
txtView.setText("Underlined Text");
4th Approach
Make use of Html.fromHtml(htmlString)
;
String htmlString="<u>Underlined Text</u>";
txtView.setText(Html.fromHtml(htmlString));
Or
txtView.setText(Html.fromHtml("<u>underlined</u> text"));
Note:
If you have added this line android:textAllCaps="true"
in your layout, then none of the above will work. For that, you have to define your string in Caps and then any of the above approach.
Solution 3 - Android
Use this
tvHide.setPaintFlags(tvHide.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);
Solution 4 - Android
Android supports string formatting using HTML tags in the strings xml. So the following would work:
<string name="label_testinghtmltags"><u>This text has an underscore</u></string>
Then you just use it as you normally would. You can see more in the documentation here
Update:
To further expand on the answer, the documentation says:
> ... the format(String, Object...)
and getString(int, Object...)
methods strip all the style information from the string. . The work-around to this is to write the HTML tags with escaped entities, which are then recovered with fromHtml(String), after the formatting takes place
For example, the resulting string from the following code snippet will not show up as containing underscored elements:
<string name="html_bold_test">This <u>%1$s</u> has an underscore</string>
String result = getString(R.string.html_bold_test, "text")
However the result from the following snippet would contain underscores:
<string name="html_bold_test">This <u> %1$s </u> has an underscore</string>
String result = Html.fromHtml(getString(R.string.html_bold_test, "text"))
Solution 5 - Android
Try this,
tv.setPaintFlags(Paint.UNDERLINE_TEXT_FLAG);

Simple and easy way to display underline in TextView
is:
yourTextView.getPaint().setUnderlineText(true);
And if you want to remove underlining for that view, you can write below code:
yourTextView.getPaint().setUnderlineText(false);
It will work even though you set android:textAllCaps="true"
Solution 7 - Android
you're almost there: just don't call toString()
on Html.fromHtml()
and you get a Spanned Object which will do the job ;)
tvHide.setText(Html.fromHtml("<p><u>Hide post</u></p>"));

Need not to use HTML properties, let's focus on java xD I had the same problem, i found the way to do it in java:
String text="Hide post";
TextView tvHide=(TextView)findViewById(R.id.text);
SpannableString spanString = new SpannableString(text);
spanString.setSpan(new UnderlineSpan(), 0, spanString.length(), 0);
tvHide.setText(spanString );

Kotlin - normal code
val text = getString(R.string.welcome)
val spannableString = SpannableString(text).apply {
setSpan(UnderlineSpan(), 0, text.length, 0)
}
text_view.text = spannableString
Kotlin - extension
fun TextView.underline(resource: Int) {
val text = context.getString(resource)
val spannableString = SpannableString(text).apply {
setSpan(UnderlineSpan(), 0, text.length, 0)
}
setText(spannableString)
}
usage:
text_view.underline(R.string.welcome)
Kotlin - binding code
@BindingAdapter("underline")
fun underline(view: TextView, resource: Int) {
if (resource == 0) return
val text = view.context.getString(resource)
val spannableString = SpannableString(text).apply {
setSpan(UnderlineSpan(), 0, text.length, 0)
}
view.text = spannableString
}
usage:
<TextView
android:id="@+id/tv_report_problem"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:underline="@{@string/common_report_problem}" />

I believe that you need to use CharSequence. You can find an example here.
Solution 11 - Android
You can do it like:
tvHide.setText(Html.fromHtml("<p><span style='text-decoration: underline'>Hide post</span></p>").toString());
Hope this helps

You can easily add a View with the height of 1dp aligning start and the end of TextView, right below it. You can also use marginTop with negative value to make the underline closer to TextView. If you use your TextView and the under inside a relative layout, it would be much easier for alignments. here is the example:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<View
android:id="@+id/viewForgotPasswordUnderline"
android:layout_width="wrap_content"
android:layout_height="1dp"
android:layout_below="@id/txtForgotPassword"
android:layout_alignStart="@id/txtForgotPassword"
android:layout_alignEnd="@id/txtForgotPassword"
android:layout_marginTop="-2dp"
android:background="@color/lightGray" />
<androidx.appcompat.widget.AppCompatTextView
android:id="@+id/txtForgotPassword"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:paddingTop="8dp"
android:text="@string/userLoginForgotPassword"
android:textColor="@color/lightGray"
android:textSize="16dp" />
</RelativeLayout>
Solution 13 - Android
In my sign_in.xml
file I used this:
<Button
android:id="@+id/signuptextlinkbtn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:background="@android:color/transparent"
android:onClick="performSingUpMethod"
android:text="Sign up now!"
android:textColor="#5B55FF"
android:textSize="15dp"
android:textStyle="bold" />
In my SignIn.java
file, I used this:
import android.graphics.Paint;
Button signuptextlinkbutton = (Button) findViewById(R.id.signuptextlinkbtn);
signuptextlinkbutton.setPaintFlags(signuptextlinkbutton.getPaintFlags()| Paint.UNDERLINE_TEXT_FLAG);
Now I can see my link underlined. It was simply text even thought I declared it as a Button
.
