Need clickable TextView in LinearLayout with TextView and Button

I have a Fragment that uses the following XML layout

<EditText android:id="@+id/username" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:hint="@string/emailId"/>
<EditText android:id="@+id/password" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:hint="@string/password" android:inputType="textPassword"/>

<Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/signin" android:onClick="signinMethod" android:focusableInTouchMode="false"/>
<TextView android:id="@+id/signUp" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/signup" android:autoLink="web" android:linksClickable="true"/>

But when I run this app, TextView is not clickable, rather a plain text is coming. Someone please help as I am new to Android. Thanks in advance.
