Question

How to set underline text on textview?

I have used following code but it is not working.

tvHide.setText(Html.fromHtml("


        

Answer 1

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>"));

Answer 2

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 );

Answer 3

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"

Answer 4

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.

Answer 5

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.

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.
