/**
 * Sets whether the content of this view is selectable by the user. The default is
 * {@code false}, meaning that the content is not selectable.
 * <p>
 * When you use a TextView to display a useful piece of information to the user (such as a
 * contact's address), make it selectable, so that the user can select and copy its
 * content. You can also use set the XML attribute
 * {@link android.R.styleable#TextView_textIsSelectable} to "true".
 * <p>
 * When you call this method to set the value of {@code textIsSelectable}, it sets
 * the flags {@code focusable}, {@code focusableInTouchMode}, {@code clickable},
 * and {@code longClickable} to the same value. These flags correspond to the attributes
 * {@link android.R.styleable#View_focusable android:focusable},
 * {@link android.R.styleable#View_focusableInTouchMode android:focusableInTouchMode},
 * {@link android.R.styleable#View_clickable android:clickable}, and
 * {@link android.R.styleable#View_longClickable android:longClickable}. To restore any of these
 * flags to a state you had set previously, call one or more of the following methods:
 * {@link #setFocusable(boolean) setFocusable()},
 * {@link #setFocusableInTouchMode(boolean) setFocusableInTouchMode()},
 * {@link #setClickable(boolean) setClickable()} or
 * {@link #setLongClickable(boolean) setLongClickable()}.
 *
 * @param selectable Whether the content of this TextView should be selectable.
