wrap_content doesn't wrap content

Question

I am a beginner in Android Programming. I was creating an app and I want to underline a text. Please have a look into my code snippet

<LinearLayout
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:orientation="vertical">
    <TextView
        android:layout_width="wrap_content"
        android:text="hello world"
        android:id="@+id/textview"
        android:layout_height="wrap_content"
         />
    <View
        android:layout_width="wrap_content"
        android:layout_height="1dp"
        android:background="@color/colorPrimary"/>
</LinearLayout>

Actually, I want the same width for both textview content and View. But View width size same as full-screen width.

To create an underline comment out the tag and add this to your code textview.setPaintFlags(textview.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG); — Giddy Naya, Jul 28 '19 at 15:04
Then set a fix size for both the view and the textview. e.g 300dp instead of wrap_content — Giddy Naya, Jul 28 '19 at 15:13
wrap_content won't work on a tag because there is nothing in it to wrap. Unlike the textview having text in it setting wrap_content will adjust the width based on the length of text. — Giddy Naya, Jul 28 '19 at 15:23
Change the View's xml to: `android:layout_width="match_parent"` — forpas, Jul 28 '19 at 15:24

To underline text in view You can edit in string like shown below,

 <resources>
    <string name="string_name">This is an <u>underline</u>.</string>
</resources>

and add this in to your text view like,

<TextView
    android:layout_width="wrap_content"
    android:text="@string/string_name"
    android:id="@+id/textview"
    android:layout_height="wrap_content" />

I hope this may will help you!!

View view will always take fullscreen if you don't specify a width or height. So, you want to use CoordinatorLayout or RelativeLayout in order to make View width the same as TextView.

wrap_content on View Android will take always as match_parent. – Davis Jul 28 '19 at 15:14
